- <chapter id="spi">
- <title>Serial Peripheral Interface (SPI)</title>
- <para>
- SPI is the "Serial Peripheral Interface", widely used with
- embedded systems because it is a simple and efficient
- interface: basically a multiplexed shift register.
- Its three signal wires hold a clock (SCK, often in the range
- of 1-20 MHz), a "Master Out, Slave In" (MOSI) data line, and
- a "Master In, Slave Out" (MISO) data line.
- SPI is a full duplex protocol; for each bit shifted out the
- MOSI line (one per clock) another is shifted in on the MISO line.
- Those bits are assembled into words of various sizes on the
- way to and from system memory.
- An additional chipselect line is usually active-low (nCS);
- four signals are normally used for each peripheral, plus
- sometimes an interrupt.
- </para>
- <para>
- The SPI bus facilities listed here provide a generalized
- interface to declare SPI busses and devices, manage them
- according to the standard Linux driver model, and perform
- input/output operations.
- At this time, only "master" side interfaces are supported,
- where Linux talks to SPI peripherals and does not implement
- such a peripheral itself.
- (Interfaces to support implementing SPI slaves would
- necessarily look different.)
- </para>
- <para>
- The programming interface is structured around two kinds of driver,
- and two kinds of device.
- A "Controller Driver" abstracts the controller hardware, which may
- be as simple as a set of GPIO pins or as complex as a pair of FIFOs
- connected to dual DMA engines on the other side of the SPI shift
- register (maximizing throughput). Such drivers bridge between
- whatever bus they sit on (often the platform bus) and SPI, and
- expose the SPI side of their device as a
- <structname>struct spi_master</structname>.
- SPI devices are children of that master, represented as a
- <structname>struct spi_device</structname> and manufactured from
- <structname>struct spi_board_info</structname> descriptors which
- are usually provided by board-specific initialization code.
- A <structname>struct spi_driver</structname> is called a
- "Protocol Driver", and is bound to a spi_device using normal
- driver model calls.
- </para>
- <para>
- The I/O model is a set of queued messages. Protocol drivers
- submit one or more <structname>struct spi_message</structname>
- objects, which are processed and completed asynchronously.
- (There are synchronous wrappers, however.) Messages are
- built from one or more <structname>struct spi_transfer</structname>
- objects, each of which wraps a full duplex SPI transfer.
- A variety of protocol tweaking options are needed, because
- different chips adopt very different policies for how they
- use the bits transferred with SPI.

- widely used where low data rate communications suffice.
- Since it's also a licensed trademark, some vendors use another
- name (such as "Two-Wire Interface", TWI) for the same bus.
- I2C only needs two signals (SCL for clock, SDA for data), conserving
- board real estate and minimizing signal quality issues.
- Most I2C devices use seven bit addresses, and bus speeds of up
- to 400 kHz; there's a high speed extension (3.4 MHz) that's not yet
- found wide use.
- I2C is a multi-master bus; open drain signaling is used to
- arbitrate between masters, as well as to handshake and to
- synchronize clocks from slower clients.

- <para>
- The Linux I2C programming interfaces support only the master
- side of bus interactions, not the slave side.
- The programming interface is structured around two kinds of driver,
- and two kinds of device.
- An I2C "Adapter Driver" abstracts the controller hardware; it binds
- to a physical device (perhaps a PCI device or platform_device) and
- exposes a <structname>struct i2c_adapter</structname> representing
- each I2C bus segment it manages.
- On each I2C bus segment will be I2C devices represented by a
- <structname>struct i2c_client</structname>. Those devices will
- be bound to a <structname>struct i2c_driver</structname>,
- which should follow the standard Linux driver model.
- (At this writing, a legacy model is more widely used.)
- There are functions to perform various I2C protocol operations; at
- this writing all such functions are usable only from task context.
- </para>
-
- <para>
- The System Management Bus (SMBus) is a sibling protocol. Most SMBus
- systems are also I2C conformant. The electrical constraints are
- tighter for SMBus, and it standardizes particular protocol messages
- and idioms. Controllers that support I2C can also support most
- SMBus operations, but SMBus controllers don't support all the protocol
- options that an I2C controller will.
- There are functions to perform various SMBus protocol operations,
- either using I2C primitives or by issuing SMBus commands to
- i2c_adapter devices which don't support those I2C operations.

review code if it is in the proper style.

+Special Usage Model of the ACPI Control Method Lid Device
+
+Copyright (C) 2016, Intel Corporation
+Author: Lv Zheng <lv.zheng@intel.com>
+
+
+Abstract:
+
+Platforms containing lids convey lid state (open/close) to OSPMs using a
+control method lid device. To implement this, the AML tables issue
+Notify(lid_device, 0x80) to notify the OSPMs whenever the lid state has
+changed. The _LID control method for the lid device must be implemented to
+report the "current" state of the lid as either "opened" or "closed".
+
+For most platforms, both the _LID method and the lid notifications are
+reliable. However, there are exceptions. In order to work with these
+exceptional buggy platforms, special restrictions and expections should be
+taken into account. This document describes the restrictions and the
+expections of the Linux ACPI lid device driver.
+
+
+1. Restrictions of the returning value of the _LID control method
+
+The _LID control method is described to return the "current" lid state.
+However the word of "current" has ambiguity, some buggy AML tables return
+the lid state upon the last lid notification instead of returning the lid
+state upon the last _LID evaluation. There won't be difference when the
+_LID control method is evaluated during the runtime, the problem is its
+initial returning value. When the AML tables implement this control method
+with cached value, the initial returning value is likely not reliable.
+There are platforms always retun "closed" as initial lid state.
+
+2. Restrictions of the lid state change notifications
+
+There are buggy AML tables never notifying when the lid device state is
+changed to "opened". Thus the "opened" notification is not guaranteed. But
+it is guaranteed that the AML tables always notify "closed" when the lid
+state is changed to "closed". The "closed" notification is normally used to
+trigger some system power saving operations on Windows. Since it is fully
+tested, it is reliable from all AML tables.
+
+3. Expections for the userspace users of the ACPI lid device driver
+
+The ACPI button driver exports the lid state to the userspace via the
+following file:
+ /proc/acpi/button/lid/LID0/state
+This file actually calls the _LID control method described above. And given
+the previous explanation, it is not reliable enough on some platforms. So
+it is advised for the userspace program to not to solely rely on this file
+to determine the actual lid state.
+
+The ACPI button driver emits the following input event to the userspace:
+ SW_LID
+The ACPI lid device driver is implemented to try to deliver the platform
+triggered events to the userspace. However, given the fact that the buggy
+firmware cannot make sure "opened"/"closed" events are paired, the ACPI
+button driver uses the following 3 modes in order not to trigger issues.
+
+If the userspace hasn't been prepared to ignore the unreliable "opened"
+events and the unreliable initial state notification, Linux users can use
+the following kernel parameters to handle the possible issues:
+A. button.lid_init_state=method:
+ When this option is specified, the ACPI button driver reports the
+ initial lid state using the returning value of the _LID control method
+ and whether the "opened"/"closed" events are paired fully relies on the
+ firmware implementation.
+ This option can be used to fix some platforms where the returning value
+ of the _LID control method is reliable but the initial lid state
+ notification is missing.
+ This option is the default behavior during the period the userspace
+ isn't ready to handle the buggy AML tables.
+B. button.lid_init_state=open:
+ When this option is specified, the ACPI button driver always reports the
+ initial lid state as "opened" and whether the "opened"/"closed" events
+ are paired fully relies on the firmware implementation.
+ This may fix some platforms where the returning value of the _LID
+ control method is not reliable and the initial lid state notification is
+ missing.
+
+If the userspace has been prepared to ignore the unreliable "opened" events
+and the unreliable initial state notification, Linux users should always
+use the following kernel parameter:
+C. button.lid_init_state=ignore:
+ When this option is specified, the ACPI button driver never reports the
+ initial lid state and there is a compensation mechanism implemented to
+ ensure that the reliable "closed" notifications can always be delievered
+ to the userspace by always pairing "closed" input events with complement
+ "opened" input events. But there is still no guarantee that the "opened"
+ notifications can be delivered to the userspace when the lid is actually
+ opens given that some AML tables do not send "opened" notifications
+ reliably.
+ In this mode, if everything is correctly implemented by the platform
+ firmware, the old userspace programs should still work. Otherwise, the
+ new userspace programs are required to work with the ACPI button driver.
+ This option will be the default behavior after the userspace is ready to
+ handle the buggy AML tables.

- Getting Coccinelle
-~~~~~~~~~~~~~~~~~~~~
-
-The semantic patches included in the kernel use features and options
-which are provided by Coccinelle version 1.0.0-rc11 and above.
-Using earlier versions will fail as the option names used by
-the Coccinelle files and coccicheck have been updated.
-
-Coccinelle is available through the package manager
-of many distributions, e.g. :
-
- - Debian
- - Fedora
- - Ubuntu
- - OpenSUSE
- - Arch Linux
- - NetBSD
- - FreeBSD
-
-
-You can get the latest version released from the Coccinelle homepage at
-http://coccinelle.lip6.fr/
-
-Information and tips about Coccinelle are also provided on the wiki
-pages at http://cocci.ekstranet.diku.dk/wiki/doku.php
-
-Once you have it, run the following command:
-
- ./configure
- make
-
-as a regular user, and install it with
-
- sudo make install
-
- Supplemental documentation
-~~~~~~~~~~~~~~~~~~~~~~~~~~~~
-
-For supplemental documentation refer to the wiki:
-
-https://bottest.wiki.kernel.org/coccicheck
-
-The wiki documentation always refers to the linux-next version of the script.
-
- Using Coccinelle on the Linux kernel
-~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
-
-A Coccinelle-specific target is defined in the top level
-Makefile. This target is named 'coccicheck' and calls the 'coccicheck'
-front-end in the 'scripts' directory.
-
-Four basic modes are defined: patch, report, context, and org. The mode to
-use is specified by setting the MODE variable with 'MODE=<mode>'.
-
-'patch' proposes a fix, when possible.
-
-'report' generates a list in the following format:
- file:line:column-column: message
-
-'context' highlights lines of interest and their context in a
-diff-like style.Lines of interest are indicated with '-'.
-
-'org' generates a report in the Org mode format of Emacs.
-
-Note that not all semantic patches implement all modes. For easy use
-of Coccinelle, the default mode is "report".
-
-Two other modes provide some common combinations of these modes.
-
-'chain' tries the previous modes in the order above until one succeeds.
-
-'rep+ctxt' runs successively the report mode and the context mode.
- It should be used with the C option (described later)
- which checks the code on a file basis.
-
-Examples:
- To make a report for every semantic patch, run the following command:
-
- make coccicheck MODE=report
-
- To produce patches, run:
-
- make coccicheck MODE=patch
-
-
-The coccicheck target applies every semantic patch available in the
-sub-directories of 'scripts/coccinelle' to the entire Linux kernel.
-
-For each semantic patch, a commit message is proposed. It gives a
-description of the problem being checked by the semantic patch, and
-includes a reference to Coccinelle.
-
-As any static code analyzer, Coccinelle produces false
-positives. Thus, reports must be carefully checked, and patches
-reviewed.
-
-To enable verbose messages set the V= variable, for example:
-
- make coccicheck MODE=report V=1
-
- Coccinelle parallelization
-~~~~~~~~~~~~~~~~~~~~~~~~~~~~
-
-By default, coccicheck tries to run as parallel as possible. To change
-the parallelism, set the J= variable. For example, to run across 4 CPUs:
-
- make coccicheck MODE=report J=4
-
-As of Coccinelle 1.0.2 Coccinelle uses Ocaml parmap for parallelization,
-if support for this is detected you will benefit from parmap parallelization.
-
-When parmap is enabled coccicheck will enable dynamic load balancing by using
-'--chunksize 1' argument, this ensures we keep feeding threads with work
-one by one, so that we avoid the situation where most work gets done by only
-a few threads. With dynamic load balancing, if a thread finishes early we keep
-feeding it more work.
-
-When parmap is enabled, if an error occurs in Coccinelle, this error
-value is propagated back, the return value of the 'make coccicheck'
-captures this return value.
-
- Using Coccinelle with a single semantic patch
-~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
-
-The optional make variable COCCI can be used to check a single
-semantic patch. In that case, the variable must be initialized with
-the name of the semantic patch to apply.
-
-For instance:
-
- make coccicheck COCCI=<my_SP.cocci> MODE=patch
-or
- make coccicheck COCCI=<my_SP.cocci> MODE=report
-
-
- Controlling Which Files are Processed by Coccinelle
-~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
-By default the entire kernel source tree is checked.
-
-To apply Coccinelle to a specific directory, M= can be used.
-For example, to check drivers/net/wireless/ one may write:
-
- make coccicheck M=drivers/net/wireless/
-
-To apply Coccinelle on a file basis, instead of a directory basis, the
-following command may be used:
-
- make C=1 CHECK="scripts/coccicheck"
-
-To check only newly edited code, use the value 2 for the C flag, i.e.
-
- make C=2 CHECK="scripts/coccicheck"
-
-In these modes, which works on a file basis, there is no information
-about semantic patches displayed, and no commit message proposed.
-
-This runs every semantic patch in scripts/coccinelle by default. The
-COCCI variable may additionally be used to only apply a single
-semantic patch as shown in the previous section.
-
-The "report" mode is the default. You can select another one with the
-MODE variable explained above.
-
- Debugging Coccinelle SmPL patches
-~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
-
-Using coccicheck is best as it provides in the spatch command line
-include options matching the options used when we compile the kernel.
-You can learn what these options are by using V=1, you could then
-manually run Coccinelle with debug options added.
-
-Alternatively you can debug running Coccinelle against SmPL patches
-by asking for stderr to be redirected to stderr, by default stderr
-is redirected to /dev/null, if you'd like to capture stderr you
-can specify the DEBUG_FILE="file.txt" option to coccicheck. For
-instance:
-
- rm -f cocci.err
- make coccicheck COCCI=scripts/coccinelle/free/kfree.cocci MODE=report DEBUG_FILE=cocci.err
- cat cocci.err
-
-You can use SPFLAGS to add debugging flags, for instance you may want to
-add both --profile --show-trying to SPFLAGS when debugging. For instance
-you may want to use:
-
- rm -f err.log
- export COCCI=scripts/coccinelle/misc/irqf_oneshot.cocci
- make coccicheck DEBUG_FILE="err.log" MODE=report SPFLAGS="--profile --show-trying" M=./drivers/mfd/arizona-irq.c
-
-err.log will now have the profiling information, while stdout will
-provide some progress information as Coccinelle moves forward with
-work.
-
-DEBUG_FILE support is only supported when using coccinelle >= 1.2.
-
- .cocciconfig support
-~~~~~~~~~~~~~~~~~~~~~~
-
-Coccinelle supports reading .cocciconfig for default Coccinelle options that
-should be used every time spatch is spawned, the order of precedence for
-variables for .cocciconfig is as follows:
-
- o Your current user's home directory is processed first
- o Your directory from which spatch is called is processed next
- o The directory provided with the --dir option is processed last, if used
-
-Since coccicheck runs through make, it naturally runs from the kernel
-proper dir, as such the second rule above would be implied for picking up a
-.cocciconfig when using 'make coccicheck'.
-
-'make coccicheck' also supports using M= targets.If you do not supply
-any M= target, it is assumed you want to target the entire kernel.
-The kernel coccicheck script has:
-
- if [ "$KBUILD_EXTMOD" = "" ] ; then
- OPTIONS="--dir $srctree $COCCIINCLUDE"
- else
- OPTIONS="--dir $KBUILD_EXTMOD $COCCIINCLUDE"
- fi
-
-KBUILD_EXTMOD is set when an explicit target with M= is used. For both cases
-the spatch --dir argument is used, as such third rule applies when whether M=
-is used or not, and when M= is used the target directory can have its own
-.cocciconfig file. When M= is not passed as an argument to coccicheck the
-target directory is the same as the directory from where spatch was called.
-
-If not using the kernel's coccicheck target, keep the above precedence
-order logic of .cocciconfig reading. If using the kernel's coccicheck target,
-override any of the kernel's .coccicheck's settings using SPFLAGS.
-
-We help Coccinelle when used against Linux with a set of sensible defaults
-options for Linux with our own Linux .cocciconfig. This hints to coccinelle
-git can be used for 'git grep' queries over coccigrep. A timeout of 200
-seconds should suffice for now.
-
-The options picked up by coccinelle when reading a .cocciconfig do not appear
-as arguments to spatch processes running on your system, to confirm what
-options will be used by Coccinelle run:
-
- spatch --print-options-only
-
-You can override with your own preferred index option by using SPFLAGS. Take
-note that when there are conflicting options Coccinelle takes precedence for
-the last options passed. Using .cocciconfig is possible to use idutils, however
-given the order of precedence followed by Coccinelle, since the kernel now
-carries its own .cocciconfig, you will need to use SPFLAGS to use idutils if
-desired. See below section "Additional flags" for more details on how to use
-idutils.
-
- Additional flags
-~~~~~~~~~~~~~~~~~~
-
-Additional flags can be passed to spatch through the SPFLAGS
-variable. This works as Coccinelle respects the last flags
-given to it when options are in conflict.
-
- make SPFLAGS=--use-glimpse coccicheck
-
-Coccinelle supports idutils as well but requires coccinelle >= 1.0.6.
-When no ID file is specified coccinelle assumes your ID database file
-is in the file .id-utils.index on the top level of the kernel, coccinelle
-carries a script scripts/idutils_index.sh which creates the database with
-
- mkid -i C --output .id-utils.index
-
-If you have another database filename you can also just symlink with this
-name.
-
- make SPFLAGS=--use-idutils coccicheck
-
-Alternatively you can specify the database filename explicitly, for
-instance:
-
- make SPFLAGS="--use-idutils /full-path/to/ID" coccicheck
-
-See spatch --help to learn more about spatch options.
-
-Note that the '--use-glimpse' and '--use-idutils' options
-require external tools for indexing the code. None of them is
-thus active by default. However, by indexing the code with
-one of these tools, and according to the cocci file used,
-spatch could proceed the entire code base more quickly.
-
- SmPL patch specific options
-~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
-
-SmPL patches can have their own requirements for options passed
-to Coccinelle. SmPL patch specific options can be provided by
-providing them at the top of the SmPL patch, for instance:
-
-// Options: --no-includes --include-headers
-
- SmPL patch Coccinelle requirements
-~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
-
-As Coccinelle features get added some more advanced SmPL patches
-may require newer versions of Coccinelle. If an SmPL patch requires
-at least a version of Coccinelle, this can be specified as follows,
-as an example if requiring at least Coccinelle >= 1.0.5:
-
-// Requires: 1.0.5
-
- Proposing new semantic patches
-~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
-
-New semantic patches can be proposed and submitted by kernel
-developers. For sake of clarity, they should be organized in the
-sub-directories of 'scripts/coccinelle/'.
-

+Coccinelle
+==========
+
+Coccinelle is a tool for pattern matching and text transformation that has
+many uses in kernel development, including the application of complex,
+tree-wide patches and detection of problematic programming patterns.
+
+Getting Coccinelle
+-------------------
+
+The semantic patches included in the kernel use features and options
+which are provided by Coccinelle version 1.0.0-rc11 and above.
+Using earlier versions will fail as the option names used by
+the Coccinelle files and coccicheck have been updated.
+
+Coccinelle is available through the package manager
+of many distributions, e.g. :
+
+ - Debian
+ - Fedora
+ - Ubuntu
+ - OpenSUSE
+ - Arch Linux
+ - NetBSD
+ - FreeBSD
+
+You can get the latest version released from the Coccinelle homepage at
+http://coccinelle.lip6.fr/
+
+Information and tips about Coccinelle are also provided on the wiki
+pages at http://cocci.ekstranet.diku.dk/wiki/doku.php
+
+Once you have it, run the following command::
+
+ ./configure
+ make
+
+as a regular user, and install it with::
+
+ sudo make install
+
+Supplemental documentation
+---------------------------
+
+For supplemental documentation refer to the wiki:
+
+https://bottest.wiki.kernel.org/coccicheck
+
+The wiki documentation always refers to the linux-next version of the script.
+
+Using Coccinelle on the Linux kernel
+------------------------------------
+
+A Coccinelle-specific target is defined in the top level
+Makefile. This target is named ``coccicheck`` and calls the ``coccicheck``
+front-end in the ``scripts`` directory.
+
+Four basic modes are defined: ``patch``, ``report``, ``context``, and
+``org``. The mode to use is specified by setting the MODE variable with
+``MODE=<mode>``.
+
+- ``patch`` proposes a fix, when possible.
+
+- ``report`` generates a list in the following format:
+ file:line:column-column: message
+
+- ``context`` highlights lines of interest and their context in a
+ diff-like style.Lines of interest are indicated with ``-``.
+
+- ``org`` generates a report in the Org mode format of Emacs.
+
+Note that not all semantic patches implement all modes. For easy use
+of Coccinelle, the default mode is "report".
+
+Two other modes provide some common combinations of these modes.
+
+- ``chain`` tries the previous modes in the order above until one succeeds.
+
+- ``rep+ctxt`` runs successively the report mode and the context mode.
+ It should be used with the C option (described later)
+ which checks the code on a file basis.
+
+Examples
+~~~~~~~~
+
+To make a report for every semantic patch, run the following command::
+
+ make coccicheck MODE=report
+
+To produce patches, run::
+
+ make coccicheck MODE=patch
+
+
+The coccicheck target applies every semantic patch available in the
+sub-directories of ``scripts/coccinelle`` to the entire Linux kernel.
+
+For each semantic patch, a commit message is proposed. It gives a
+description of the problem being checked by the semantic patch, and
+includes a reference to Coccinelle.
+
+As any static code analyzer, Coccinelle produces false
+positives. Thus, reports must be carefully checked, and patches
+reviewed.
+
+To enable verbose messages set the V= variable, for example::
+
+ make coccicheck MODE=report V=1
+
+Coccinelle parallelization
+---------------------------
+
+By default, coccicheck tries to run as parallel as possible. To change
+the parallelism, set the J= variable. For example, to run across 4 CPUs::
+
+ make coccicheck MODE=report J=4
+
+As of Coccinelle 1.0.2 Coccinelle uses Ocaml parmap for parallelization,
+if support for this is detected you will benefit from parmap parallelization.
+
+When parmap is enabled coccicheck will enable dynamic load balancing by using
+``--chunksize 1`` argument, this ensures we keep feeding threads with work
+one by one, so that we avoid the situation where most work gets done by only
+a few threads. With dynamic load balancing, if a thread finishes early we keep
+feeding it more work.
+
+When parmap is enabled, if an error occurs in Coccinelle, this error
+value is propagated back, the return value of the ``make coccicheck``
+captures this return value.
+
+Using Coccinelle with a single semantic patch
+---------------------------------------------
+
+The optional make variable COCCI can be used to check a single
+semantic patch. In that case, the variable must be initialized with
+the name of the semantic patch to apply.
+
+For instance::
+
+ make coccicheck COCCI=<my_SP.cocci> MODE=patch
+
+or::
+
+ make coccicheck COCCI=<my_SP.cocci> MODE=report
+
+
+Controlling Which Files are Processed by Coccinelle
+---------------------------------------------------
+
+By default the entire kernel source tree is checked.
+
+To apply Coccinelle to a specific directory, ``M=`` can be used.
+For example, to check drivers/net/wireless/ one may write::
+
+ make coccicheck M=drivers/net/wireless/
+
+To apply Coccinelle on a file basis, instead of a directory basis, the
+following command may be used::
+
+ make C=1 CHECK="scripts/coccicheck"
+
+To check only newly edited code, use the value 2 for the C flag, i.e.::
+
+ make C=2 CHECK="scripts/coccicheck"
+
+In these modes, which works on a file basis, there is no information
+about semantic patches displayed, and no commit message proposed.
+
+This runs every semantic patch in scripts/coccinelle by default. The
+COCCI variable may additionally be used to only apply a single
+semantic patch as shown in the previous section.
+
+The "report" mode is the default. You can select another one with the
+MODE variable explained above.
+
+Debugging Coccinelle SmPL patches
+---------------------------------
+
+Using coccicheck is best as it provides in the spatch command line
+include options matching the options used when we compile the kernel.
+You can learn what these options are by using V=1, you could then
+manually run Coccinelle with debug options added.
+
+Alternatively you can debug running Coccinelle against SmPL patches
+by asking for stderr to be redirected to stderr, by default stderr
+is redirected to /dev/null, if you'd like to capture stderr you
+can specify the ``DEBUG_FILE="file.txt"`` option to coccicheck. For
+instance::
+
+ rm -f cocci.err
+ make coccicheck COCCI=scripts/coccinelle/free/kfree.cocci MODE=report DEBUG_FILE=cocci.err
+ cat cocci.err
+
+You can use SPFLAGS to add debugging flags, for instance you may want to
+add both --profile --show-trying to SPFLAGS when debugging. For instance
+you may want to use::
+
+ rm -f err.log
+ export COCCI=scripts/coccinelle/misc/irqf_oneshot.cocci
+ make coccicheck DEBUG_FILE="err.log" MODE=report SPFLAGS="--profile --show-trying" M=./drivers/mfd/arizona-irq.c
+
+err.log will now have the profiling information, while stdout will
+provide some progress information as Coccinelle moves forward with
+work.
+
+DEBUG_FILE support is only supported when using coccinelle >= 1.2.
+
+.cocciconfig support
+--------------------
+
+Coccinelle supports reading .cocciconfig for default Coccinelle options that
+should be used every time spatch is spawned, the order of precedence for
+variables for .cocciconfig is as follows:
+
+- Your current user's home directory is processed first
+- Your directory from which spatch is called is processed next
+- The directory provided with the --dir option is processed last, if used
+
+Since coccicheck runs through make, it naturally runs from the kernel
+proper dir, as such the second rule above would be implied for picking up a
+.cocciconfig when using ``make coccicheck``.
+
+``make coccicheck`` also supports using M= targets.If you do not supply
+any M= target, it is assumed you want to target the entire kernel.
+The kernel coccicheck script has::
+
+ if [ "$KBUILD_EXTMOD" = "" ] ; then
+ OPTIONS="--dir $srctree $COCCIINCLUDE"
+ else
+ OPTIONS="--dir $KBUILD_EXTMOD $COCCIINCLUDE"
+ fi
+
+KBUILD_EXTMOD is set when an explicit target with M= is used. For both cases
+the spatch --dir argument is used, as such third rule applies when whether M=
+is used or not, and when M= is used the target directory can have its own
+.cocciconfig file. When M= is not passed as an argument to coccicheck the
+target directory is the same as the directory from where spatch was called.
+
+If not using the kernel's coccicheck target, keep the above precedence
+order logic of .cocciconfig reading. If using the kernel's coccicheck target,
+override any of the kernel's .coccicheck's settings using SPFLAGS.
+
+We help Coccinelle when used against Linux with a set of sensible defaults
+options for Linux with our own Linux .cocciconfig. This hints to coccinelle
+git can be used for ``git grep`` queries over coccigrep. A timeout of 200
+seconds should suffice for now.
+
+The options picked up by coccinelle when reading a .cocciconfig do not appear
+as arguments to spatch processes running on your system, to confirm what
+options will be used by Coccinelle run::
+
+ spatch --print-options-only
+
+You can override with your own preferred index option by using SPFLAGS. Take
+note that when there are conflicting options Coccinelle takes precedence for
+the last options passed. Using .cocciconfig is possible to use idutils, however
+given the order of precedence followed by Coccinelle, since the kernel now
+carries its own .cocciconfig, you will need to use SPFLAGS to use idutils if
+desired. See below section "Additional flags" for more details on how to use
+idutils.
+
+Additional flags
+----------------
+
+Additional flags can be passed to spatch through the SPFLAGS
+variable. This works as Coccinelle respects the last flags
+given to it when options are in conflict. ::
+
+ make SPFLAGS=--use-glimpse coccicheck
+
+Coccinelle supports idutils as well but requires coccinelle >= 1.0.6.
+When no ID file is specified coccinelle assumes your ID database file
+is in the file .id-utils.index on the top level of the kernel, coccinelle
+carries a script scripts/idutils_index.sh which creates the database with::
+
+ mkid -i C --output .id-utils.index
+
+If you have another database filename you can also just symlink with this
+name. ::
+
+ make SPFLAGS=--use-idutils coccicheck
+
+Alternatively you can specify the database filename explicitly, for
+instance::
+
+ make SPFLAGS="--use-idutils /full-path/to/ID" coccicheck
+
+See ``spatch --help`` to learn more about spatch options.
+
+Note that the ``--use-glimpse`` and ``--use-idutils`` options
+require external tools for indexing the code. None of them is
+thus active by default. However, by indexing the code with
+one of these tools, and according to the cocci file used,
+spatch could proceed the entire code base more quickly.
+
+SmPL patch specific options
+---------------------------
+
+SmPL patches can have their own requirements for options passed
+to Coccinelle. SmPL patch specific options can be provided by
+providing them at the top of the SmPL patch, for instance::
+
+ // Options: --no-includes --include-headers
+
+SmPL patch Coccinelle requirements
+----------------------------------
+
+As Coccinelle features get added some more advanced SmPL patches
+may require newer versions of Coccinelle. If an SmPL patch requires
+at least a version of Coccinelle, this can be specified as follows,
+as an example if requiring at least Coccinelle >= 1.0.5::
+
+ // Requires: 1.0.5
+
+Proposing new semantic patches
+-------------------------------
+
+New semantic patches can be proposed and submitted by kernel
+developers. For sake of clarity, they should be organized in the
+sub-directories of ``scripts/coccinelle/``.
+
+
+Detailed description of the ``report`` mode

+Using gcov with the Linux kernel
+================================
+
+gcov profiling kernel support enables the use of GCC's coverage testing
+tool gcov_ with the Linux kernel. Coverage data of a running kernel
+is exported in gcov-compatible format via the "gcov" debugfs directory.
+To get coverage data for a specific file, change to the kernel build
+directory and use gcov with the ``-o`` option as follows (requires root)::
+
+ # cd /tmp/linux-out
+ # gcov -o /sys/kernel/debug/gcov/tmp/linux-out/kernel spinlock.c
+
+This will create source code files annotated with execution counts
+in the current directory. In addition, graphical gcov front-ends such
+as lcov_ can be used to automate the process of collecting data
+for the entire kernel and provide coverage overviews in HTML format.
+
+Possible uses:
+
+* debugging (has this line been reached at all?)
+* test improvement (how do I change my test to cover these lines?)
+* minimizing kernel configurations (do I need this option if the
+ associated code is never run?)
+
+.. _gcov: http://gcc.gnu.org/onlinedocs/gcc/Gcov.html
+.. _lcov: http://ltp.sourceforge.net/coverage/lcov.php
+
+
+Preparation
+-----------
+
+Configure the kernel with::
+
+ CONFIG_DEBUG_FS=y
+ CONFIG_GCOV_KERNEL=y
+
+select the gcc's gcov format, default is autodetect based on gcc version::
+
+ CONFIG_GCOV_FORMAT_AUTODETECT=y
+
+and to get coverage data for the entire kernel::
+
+ CONFIG_GCOV_PROFILE_ALL=y
+
+Note that kernels compiled with profiling flags will be significantly
+larger and run slower. Also CONFIG_GCOV_PROFILE_ALL may not be supported
+on all architectures.
+
+Profiling data will only become accessible once debugfs has been
+mounted::
+
+ mount -t debugfs none /sys/kernel/debug
+
+
+Customization
+-------------
+
+To enable profiling for specific files or directories, add a line
+similar to the following to the respective kernel Makefile:
+
+- For a single file (e.g. main.o)::
+
+ GCOV_PROFILE_main.o := y
+
+- For all files in one directory::
+
+ GCOV_PROFILE := y
+
+To exclude files from being profiled even when CONFIG_GCOV_PROFILE_ALL
+is specified, use::
+
+ GCOV_PROFILE_main.o := n
+
+and::
+
+ GCOV_PROFILE := n
+
+Only files which are linked to the main kernel image or are compiled as
+kernel modules are supported by this mechanism.
+
+
+Files
+-----
+
+The gcov kernel support creates the following files in debugfs:
+
+``/sys/kernel/debug/gcov``
+ Parent directory for all gcov-related files.
+
+``/sys/kernel/debug/gcov/reset``
+ Global reset file: resets all coverage data to zero when
+ written to.
+
+``/sys/kernel/debug/gcov/path/to/compile/dir/file.gcda``
+ The actual gcov data file as understood by the gcov
+ tool. Resets file coverage data to zero when written to.
+
+``/sys/kernel/debug/gcov/path/to/compile/dir/file.gcno``
+ Symbolic link to a static data file required by the gcov
+ tool. This file is generated by gcc when compiling with
+ option ``-ftest-coverage``.
+
+
+Modules
+-------
+
+Kernel modules may contain cleanup code which is only run during
+module unload time. The gcov mechanism provides a means to collect
+coverage data for such code by keeping a copy of the data associated
+with the unloaded module. This data remains available through debugfs.
+Once the module is loaded again, the associated coverage counters are
+initialized with the data from its previous instantiation.
+
+This behavior can be deactivated by specifying the gcov_persist kernel
+parameter::
+
+ gcov_persist=0
+
+At run-time, a user can also choose to discard data for an unloaded
+module by writing to its data file or the global reset file.
+
+
+Separated build and test machines
+---------------------------------
+
+The gcov kernel profiling infrastructure is designed to work out-of-the
+box for setups where kernels are built and run on the same machine. In
+cases where the kernel runs on a separate machine, special preparations
+must be made, depending on where the gcov tool is used:
+
+a) gcov is run on the TEST machine
+
+ The gcov tool version on the test machine must be compatible with the
+ gcc version used for kernel build. Also the following files need to be
+ copied from build to test machine:
+
+ from the source tree:
+ - all C source files + headers
+
+ from the build tree:
+ - all C source files + headers
+ - all .gcda and .gcno files
+ - all links to directories
+
+ It is important to note that these files need to be placed into the
+ exact same file system location on the test machine as on the build
+ machine. If any of the path components is symbolic link, the actual
+ directory needs to be used instead (due to make's CURDIR handling).
+
+b) gcov is run on the BUILD machine
+
+ The following files need to be copied after each test case from test
+ to build machine:
+
+ from the gcov directory in sysfs:
+ - all .gcda files
+ - all links to .gcno files
+
+ These files can be copied to any location on the build machine. gcov
+ must then be called with the -o option pointing to that directory.
+
+ Example directory setup on the build machine::
+
+ /tmp/linux: kernel source tree
+ /tmp/out: kernel build directory as specified by make O=
+ /tmp/coverage: location of the files copied from the test machine
+
+ [user@build] cd /tmp/out
+ [user@build] gcov -o /tmp/coverage/tmp/out/init main.c
+
+
+Troubleshooting
+---------------
+
+Problem
+ Compilation aborts during linker step.
+
+Cause
+ Profiling flags are specified for source files which are not
+ linked to the main kernel or which are linked by a custom
+ linker procedure.
+
+Solution
+ Exclude affected source files from profiling by specifying
+ ``GCOV_PROFILE := n`` or ``GCOV_PROFILE_basename.o := n`` in the
+ corresponding Makefile.
+
+Problem
+ Files copied from sysfs appear empty or incomplete.
+
+Cause
+ Due to the way seq_file works, some tools such as cp or tar
+ may not correctly copy files from sysfs.
+
+Solution
+ Use ``cat``' to read ``.gcda`` files and ``cp -d`` to copy links.
+ Alternatively use the mechanism shown in Appendix B.
+
+
+Appendix A: gather_on_build.sh
+------------------------------
+
+Sample script to gather coverage meta files on the build machine
+(see 6a)::
+
+ #!/bin/bash
+
+ KSRC=$1
+ KOBJ=$2
+ DEST=$3
+
+ if [ -z "$KSRC" ] || [ -z "$KOBJ" ] || [ -z "$DEST" ]; then
+ echo "Usage: $0 <ksrc directory> <kobj directory> <output.tar.gz>" >&2
+ exit 1

+
+Debugging kernel and modules via gdb
+====================================
+
+The kernel debugger kgdb, hypervisors like QEMU or JTAG-based hardware
+interfaces allow to debug the Linux kernel and its modules during runtime
+using gdb. Gdb comes with a powerful scripting interface for python. The
+kernel provides a collection of helper scripts that can simplify typical
+kernel debugging steps. This is a short tutorial about how to enable and use
+them. It focuses on QEMU/KVM virtual machines as target, but the examples can
+be transferred to the other gdb stubs as well.
+
+
+Requirements
+------------
+
+- gdb 7.2+ (recommended: 7.4+) with python support enabled (typically true
+ for distributions)
+
+
+Setup
+-----
+
+- Create a virtual Linux machine for QEMU/KVM (see www.linux-kvm.org and
+ www.qemu.org for more details). For cross-development,
+ http://landley.net/aboriginal/bin keeps a pool of machine images and
+ toolchains that can be helpful to start from.
+
+- Build the kernel with CONFIG_GDB_SCRIPTS enabled, but leave
+ CONFIG_DEBUG_INFO_REDUCED off. If your architecture supports
+ CONFIG_FRAME_POINTER, keep it enabled.
+
+- Install that kernel on the guest.
+ Alternatively, QEMU allows to boot the kernel directly using -kernel,
+ -append, -initrd command line switches. This is generally only useful if
+ you do not depend on modules. See QEMU documentation for more details on
+ this mode.
+
+- Enable the gdb stub of QEMU/KVM, either
+
+ - at VM startup time by appending "-s" to the QEMU command line
+
+ or
+
+ - during runtime by issuing "gdbserver" from the QEMU monitor
+ console
+
+- cd /path/to/linux-build
+
+- Start gdb: gdb vmlinux
+
+ Note: Some distros may restrict auto-loading of gdb scripts to known safe
+ directories. In case gdb reports to refuse loading vmlinux-gdb.py, add::
+
+ add-auto-load-safe-path /path/to/linux-build
+
+ to ~/.gdbinit. See gdb help for more details.
+
+- Attach to the booted guest::
+
+ (gdb) target remote :1234
+
+
+Examples of using the Linux-provided gdb helpers
+------------------------------------------------
+
+- Load module (and main kernel) symbols::
+
+ (gdb) lx-symbols
+ loading vmlinux
+ scanning for modules in /home/user/linux/build
+ loading @0xffffffffa0020000: /home/user/linux/build/net/netfilter/xt_tcpudp.ko
+ loading @0xffffffffa0016000: /home/user/linux/build/net/netfilter/xt_pkttype.ko
+ loading @0xffffffffa0002000: /home/user/linux/build/net/netfilter/xt_limit.ko
+ loading @0xffffffffa00ca000: /home/user/linux/build/net/packet/af_packet.ko
+ loading @0xffffffffa003c000: /home/user/linux/build/fs/fuse/fuse.ko
+ ...
+ loading @0xffffffffa0000000: /home/user/linux/build/drivers/ata/ata_generic.ko
+
+- Set a breakpoint on some not yet loaded module function, e.g.::
+
+ (gdb) b btrfs_init_sysfs
+ Function "btrfs_init_sysfs" not defined.
+ Make breakpoint pending on future shared library load? (y or [n]) y
+ Breakpoint 1 (btrfs_init_sysfs) pending.
+
+- Continue the target::
+
+ (gdb) c
+
+- Load the module on the target and watch the symbols being loaded as well as
+ the breakpoint hit::
+
+ loading @0xffffffffa0034000: /home/user/linux/build/lib/libcrc32c.ko
+ loading @0xffffffffa0050000: /home/user/linux/build/lib/lzo/lzo_compress.ko
+ loading @0xffffffffa006e000: /home/user/linux/build/lib/zlib_deflate/zlib_deflate.ko
+ loading @0xffffffffa01b1000: /home/user/linux/build/fs/btrfs/btrfs.ko
+
+ Breakpoint 1, btrfs_init_sysfs () at /home/user/linux/fs/btrfs/sysfs.c:36
+ 36 btrfs_kset = kset_create_and_add("btrfs", NULL, fs_kobj);
+
+- Dump the log buffer of the target kernel::
+
+ (gdb) lx-dmesg
+ [ 0.000000] Initializing cgroup subsys cpuset
+ [ 0.000000] Initializing cgroup subsys cpu

+The Kernel Address Sanitizer (KASAN)
+====================================
+
+Overview
+--------
+
+KernelAddressSANitizer (KASAN) is a dynamic memory error detector. It provides
+a fast and comprehensive solution for finding use-after-free and out-of-bounds
+bugs.
+
+KASAN uses compile-time instrumentation for checking every memory access,
+therefore you will need a GCC version 4.9.2 or later. GCC 5.0 or later is
+required for detection of out-of-bounds accesses to stack or global variables.
+
+Currently KASAN is supported only for the x86_64 and arm64 architectures.
+
+Usage
+-----
+
+To enable KASAN configure kernel with::
+
+ CONFIG_KASAN = y
+
+and choose between CONFIG_KASAN_OUTLINE and CONFIG_KASAN_INLINE. Outline and
+inline are compiler instrumentation types. The former produces smaller binary
+the latter is 1.1 - 2 times faster. Inline instrumentation requires a GCC
+version 5.0 or later.
+
+KASAN works with both SLUB and SLAB memory allocators.
+For better bug detection and nicer reporting, enable CONFIG_STACKTRACE.
+
+To disable instrumentation for specific files or directories, add a line
+similar to the following to the respective kernel Makefile:
+
+- For a single file (e.g. main.o)::
+
+ KASAN_SANITIZE_main.o := n
+
+- For all files in one directory::
+
+ KASAN_SANITIZE := n
+
+Error reports

+
+A typical out of bounds access report looks like this::

+ ==================================================================
+
+The header of the report discribe what kind of bug happened and what kind of
+access caused it. It's followed by the description of the accessed slub object
+(see 'SLUB Debug output' section in Documentation/vm/slub.txt for details) and
+the description of the accessed memory page.
+
+In the last section the report shows memory state around the accessed address.
+Reading this part requires some understanding of how KASAN works.
+
+The state of each 8 aligned bytes of memory is encoded in one shadow byte.
+Those 8 bytes can be accessible, partially accessible, freed or be a redzone.
+We use the following encoding for each shadow byte: 0 means that all 8 bytes
+of the corresponding memory region are accessible; number N (1 <= N <= 7) means
+that the first N bytes are accessible, and other (8 - N) bytes are not;
+any negative value indicates that the entire 8-byte word is inaccessible.
+We use different negative values to distinguish between different kinds of
+inaccessible memory like redzones or freed memory (see mm/kasan/kasan.h).
+
+In the report above the arrows point to the shadow byte 03, which means that
+the accessed address is partially accessible.
+
+
+Implementation details
+----------------------
+
+From a high level, our approach to memory error detection is similar to that
+of kmemcheck: use shadow memory to record whether each byte of memory is safe
+to access, and use compile-time instrumentation to check shadow memory on each
+memory access.
+
+AddressSanitizer dedicates 1/8 of kernel memory to its shadow memory
+(e.g. 16TB to cover 128TB on x86_64) and uses direct mapping with a scale and
+offset to translate a memory address to its corresponding shadow address.
+
+Here is the function which translates an address to its corresponding shadow
+address::
+
+ static inline void *kasan_mem_to_shadow(const void *addr)
+ {
+ return ((unsigned long)addr >> KASAN_SHADOW_SCALE_SHIFT)
+ + KASAN_SHADOW_OFFSET;
+ }
+
+where ``KASAN_SHADOW_SCALE_SHIFT = 3``.
+
+Compile-time instrumentation used for checking memory accesses. Compiler inserts
+function calls (__asan_load*(addr), __asan_store*(addr)) before each memory
+access of size 1, 2, 4, 8 or 16. These functions check whether memory access is
+valid or not by checking corresponding shadow memory.
+
+GCC 5.0 has possibility to perform inline instrumentation. Instead of making
+function calls GCC directly inserts the code to check the shadow memory.
+This option significantly enlarges kernel but it gives x1.1-x2 performance
+boost over outline instrumented kernel.

+kcov: code coverage for fuzzing
+===============================
+
+kcov exposes kernel code coverage information in a form suitable for coverage-
+guided fuzzing (randomized testing). Coverage data of a running kernel is
+exported via the "kcov" debugfs file. Coverage collection is enabled on a task
+basis, and thus it can capture precise coverage of a single system call.
+
+Note that kcov does not aim to collect as much coverage as possible. It aims
+to collect more or less stable coverage that is function of syscall inputs.
+To achieve this goal it does not collect coverage in soft/hard interrupts
+and instrumentation of some inherently non-deterministic parts of kernel is
+disbled (e.g. scheduler, locking).
+
+Usage
+-----
+
+Configure the kernel with::
+
+ CONFIG_KCOV=y
+
+CONFIG_KCOV requires gcc built on revision 231296 or later.
+Profiling data will only become accessible once debugfs has been mounted::
+
+ mount -t debugfs none /sys/kernel/debug
+
+The following program demonstrates kcov usage from within a test program::
+
+ #include <stdio.h>
+ #include <stddef.h>
+ #include <stdint.h>
+ #include <stdlib.h>
+ #include <sys/types.h>
+ #include <sys/stat.h>
+ #include <sys/ioctl.h>

+ #define KCOV_ENABLE _IO('c', 100)
+ #define KCOV_DISABLE _IO('c', 101)
+ #define COVER_SIZE (64<<10)
+
+ int main(int argc, char **argv)
+ {
+ int fd;
+ unsigned long *cover, n, i;
+
+ /* A single fd descriptor allows coverage collection on a single
+ * thread.
+ */
+ fd = open("/sys/kernel/debug/kcov", O_RDWR);
+ if (fd == -1)
+ perror("open"), exit(1);
+ /* Setup trace mode and trace size. */
+ if (ioctl(fd, KCOV_INIT_TRACE, COVER_SIZE))
+ perror("ioctl"), exit(1);
+ /* Mmap buffer shared between kernel- and user-space. */
+ cover = (unsigned long*)mmap(NULL, COVER_SIZE * sizeof(unsigned long),
+ PROT_READ | PROT_WRITE, MAP_SHARED, fd, 0);
+ if ((void*)cover == MAP_FAILED)
+ perror("mmap"), exit(1);
+ /* Enable coverage collection on the current thread. */
+ if (ioctl(fd, KCOV_ENABLE, 0))
+ perror("ioctl"), exit(1);
+ /* Reset coverage from the tail of the ioctl() call. */
+ __atomic_store_n(&cover[0], 0, __ATOMIC_RELAXED);
+ /* That's the target syscal call. */
+ read(-1, NULL, 0);
+ /* Read number of PCs collected. */
+ n = __atomic_load_n(&cover[0], __ATOMIC_RELAXED);
+ for (i = 0; i < n; i++)
+ printf("0x%lx\n", cover[i + 1]);
+ /* Disable coverage collection for the current thread. After this call
+ * coverage can be enabled for a different thread.
+ */
+ if (ioctl(fd, KCOV_DISABLE, 0))
+ perror("ioctl"), exit(1);
+ /* Free resources. */
+ if (munmap(cover, COVER_SIZE * sizeof(unsigned long)))
+ perror("munmap"), exit(1);
+ if (close(fd))
+ perror("close"), exit(1);
+ return 0;
+ }
+
+After piping through addr2line output of the program looks as follows::
+
+ SyS_read
+ fs/read_write.c:562
+ __fdget_pos
+ fs/file.c:774
+ __fget_light
+ fs/file.c:746
+ __fget_light
+ fs/file.c:750
+ __fget_light
+ fs/file.c:760
+ __fdget_pos
+ fs/file.c:784
+ SyS_read
+ fs/read_write.c:562
+
+If a program needs to collect coverage from several threads (independently),
+it needs to open /sys/kernel/debug/kcov in each thread separately.
+
+The interface is fine-grained to allow efficient forking of test processes.
+That is, a parent process opens /sys/kernel/debug/kcov, enables trace mode,
+mmaps coverage buffer and then forks child processes in a loop. Child processes
+only need to enable coverage (disable happens automatically on thread end).

+Getting started with kmemcheck
+==============================
+
+Vegard Nossum <vegardno@ifi.uio.no>
+
+
+Introduction
+------------
+
+kmemcheck is a debugging feature for the Linux Kernel. More specifically, it
+is a dynamic checker that detects and warns about some uses of uninitialized
+memory.
+
+Userspace programmers might be familiar with Valgrind's memcheck. The main
+difference between memcheck and kmemcheck is that memcheck works for userspace
+programs only, and kmemcheck works for the kernel only. The implementations
+are of course vastly different. Because of this, kmemcheck is not as accurate
+as memcheck, but it turns out to be good enough in practice to discover real
+programmer errors that the compiler is not able to find through static
+analysis.
+
+Enabling kmemcheck on a kernel will probably slow it down to the extent that
+the machine will not be usable for normal workloads such as e.g. an
+interactive desktop. kmemcheck will also cause the kernel to use about twice
+as much memory as normal. For this reason, kmemcheck is strictly a debugging
+feature.
+
+
+Downloading
+-----------
+
+As of version 2.6.31-rc1, kmemcheck is included in the mainline kernel.
+
+
+Configuring and compiling
+-------------------------
+
+kmemcheck only works for the x86 (both 32- and 64-bit) platform. A number of
+configuration variables must have specific settings in order for the kmemcheck
+menu to even appear in "menuconfig". These are:
+
+- ``CONFIG_CC_OPTIMIZE_FOR_SIZE=n``
+ This option is located under "General setup" / "Optimize for size".
+
+ Without this, gcc will use certain optimizations that usually lead to
+ false positive warnings from kmemcheck. An example of this is a 16-bit
+ field in a struct, where gcc may load 32 bits, then discard the upper
+ 16 bits. kmemcheck sees only the 32-bit load, and may trigger a
+ warning for the upper 16 bits (if they're uninitialized).
+
+- ``CONFIG_SLAB=y`` or ``CONFIG_SLUB=y``
+ This option is located under "General setup" / "Choose SLAB
+ allocator".
+
+- ``CONFIG_FUNCTION_TRACER=n``
+ This option is located under "Kernel hacking" / "Tracers" / "Kernel
+ Function Tracer"
+
+ When function tracing is compiled in, gcc emits a call to another
+ function at the beginning of every function. This means that when the
+ page fault handler is called, the ftrace framework will be called
+ before kmemcheck has had a chance to handle the fault. If ftrace then
+ modifies memory that was tracked by kmemcheck, the result is an
+ endless recursive page fault.
+
+- ``CONFIG_DEBUG_PAGEALLOC=n``
+ This option is located under "Kernel hacking" / "Memory Debugging"
+ / "Debug page memory allocations".
+
+In addition, I highly recommend turning on ``CONFIG_DEBUG_INFO=y``. This is also
+located under "Kernel hacking". With this, you will be able to get line number
+information from the kmemcheck warnings, which is extremely valuable in
+debugging a problem. This option is not mandatory, however, because it slows
+down the compilation process and produces a much bigger kernel image.
+
+Now the kmemcheck menu should be visible (under "Kernel hacking" / "Memory
+Debugging" / "kmemcheck: trap use of uninitialized memory"). Here follows
+a description of the kmemcheck configuration variables:
+
+- ``CONFIG_KMEMCHECK``
+ This must be enabled in order to use kmemcheck at all...
+
+- ``CONFIG_KMEMCHECK_``[``DISABLED`` | ``ENABLED`` | ``ONESHOT``]``_BY_DEFAULT``
+ This option controls the status of kmemcheck at boot-time. "Enabled"
+ will enable kmemcheck right from the start, "disabled" will boot the
+ kernel as normal (but with the kmemcheck code compiled in, so it can
+ be enabled at run-time after the kernel has booted), and "one-shot" is
+ a special mode which will turn kmemcheck off automatically after
+ detecting the first use of uninitialized memory.
+
+ If you are using kmemcheck to actively debug a problem, then you
+ probably want to choose "enabled" here.
+
+ The one-shot mode is mostly useful in automated test setups because it
+ can prevent floods of warnings and increase the chances of the machine
+ surviving in case something is really wrong. In other cases, the one-
+ shot mode could actually be counter-productive because it would turn
+ itself off at the very first error -- in the case of a false positive
+ too -- and this would come in the way of debugging the specific
+ problem you were interested in.
+
+ If you would like to use your kernel as normal, but with a chance to
+ enable kmemcheck in case of some problem, it might be a good idea to
+ choose "disabled" here. When kmemcheck is disabled, most of the run-
+ time overhead is not incurred, and the kernel will be almost as fast
+ as normal.
+
+- ``CONFIG_KMEMCHECK_QUEUE_SIZE``
+ Select the maximum number of error reports to store in an internal
+ (fixed-size) buffer. Since errors can occur virtually anywhere and in
+ any context, we need a temporary storage area which is guaranteed not
+ to generate any other page faults when accessed. The queue will be
+ emptied as soon as a tasklet may be scheduled. If the queue is full,
+ new error reports will be lost.
+
+ The default value of 64 is probably fine. If some code produces more
+ than 64 errors within an irqs-off section, then the code is likely to
+ produce many, many more, too, and these additional reports seldom give
+ any more information (the first report is usually the most valuable
+ anyway).
+
+ This number might have to be adjusted if you are not using serial
+ console or similar to capture the kernel log. If you are using the
+ "dmesg" command to save the log, then getting a lot of kmemcheck
+ warnings might overflow the kernel log itself, and the earlier reports
+ will get lost in that way instead. Try setting this to 10 or so on
+ such a setup.
+
+- ``CONFIG_KMEMCHECK_SHADOW_COPY_SHIFT``
+ Select the number of shadow bytes to save along with each entry of the
+ error-report queue. These bytes indicate what parts of an allocation
+ are initialized, uninitialized, etc. and will be displayed when an
+ error is detected to help the debugging of a particular problem.
+
+ The number entered here is actually the logarithm of the number of
+ bytes that will be saved. So if you pick for example 5 here, kmemcheck
+ will save 2^5 = 32 bytes.
+
+ The default value should be fine for debugging most problems. It also
+ fits nicely within 80 columns.
+
+- ``CONFIG_KMEMCHECK_PARTIAL_OK``
+ This option (when enabled) works around certain GCC optimizations that
+ produce 32-bit reads from 16-bit variables where the upper 16 bits are
+ thrown away afterwards.
+
+ The default value (enabled) is recommended. This may of course hide
+ some real errors, but disabling it would probably produce a lot of
+ false positives.
+
+- ``CONFIG_KMEMCHECK_BITOPS_OK``
+ This option silences warnings that would be generated for bit-field
+ accesses where not all the bits are initialized at the same time. This
+ may also hide some real bugs.
+
+ This option is probably obsolete, or it should be replaced with
+ the kmemcheck-/bitfield-annotations for the code in question. The
+ default value is therefore fine.
+
+Now compile the kernel as usual.
+
+
+How to use
+----------
+
+Booting
+~~~~~~~
+
+First some information about the command-line options. There is only one
+option specific to kmemcheck, and this is called "kmemcheck". It can be used
+to override the default mode as chosen by the ``CONFIG_KMEMCHECK_*_BY_DEFAULT``
+option. Its possible settings are:
+
+- ``kmemcheck=0`` (disabled)
+- ``kmemcheck=1`` (enabled)
+- ``kmemcheck=2`` (one-shot mode)
+
+If SLUB debugging has been enabled in the kernel, it may take precedence over
+kmemcheck in such a way that the slab caches which are under SLUB debugging
+will not be tracked by kmemcheck. In order to ensure that this doesn't happen
+(even though it shouldn't by default), use SLUB's boot option ``slub_debug``,
+like this: ``slub_debug=-``
+
+In fact, this option may also be used for fine-grained control over SLUB vs.
+kmemcheck. For example, if the command line includes
+``kmemcheck=1 slub_debug=,dentry``, then SLUB debugging will be used only
+for the "dentry" slab cache, and with kmemcheck tracking all the other
+caches. This is advanced usage, however, and is not generally recommended.
+
+
+Run-time enable/disable
+~~~~~~~~~~~~~~~~~~~~~~~
+
+When the kernel has booted, it is possible to enable or disable kmemcheck at
+run-time. WARNING: This feature is still experimental and may cause false
+positive warnings to appear. Therefore, try not to use this. If you find that
+it doesn't work properly (e.g. you see an unreasonable amount of warnings), I
+will be happy to take bug reports.
+
+Use the file ``/proc/sys/kernel/kmemcheck`` for this purpose, e.g.::
+
+ $ echo 0 > /proc/sys/kernel/kmemcheck # disables kmemcheck
+
+The numbers are the same as for the ``kmemcheck=`` command-line option.
+
+
+Debugging

+
+The single most valuable information in this report is the RIP (or EIP on 32-
+bit) value. This will help us pinpoint exactly which instruction that caused
+the warning.
+
+If your kernel was compiled with ``CONFIG_DEBUG_INFO=y``, then all we have to do
+is give this address to the addr2line program, like this::
+
+ $ addr2line -e vmlinux -i ffffffff8104ede8
+ arch/x86/include/asm/string_64.h:12
+ include/asm-generic/siginfo.h:287
+ kernel/signal.c:380
+ kernel/signal.c:410
+
+The "``-e vmlinux``" tells addr2line which file to look in. **IMPORTANT:**
+This must be the vmlinux of the kernel that produced the warning in the
+first place! If not, the line number information will almost certainly be
+wrong.
+
+The "``-i``" tells addr2line to also print the line numbers of inlined
+functions. In this case, the flag was very important, because otherwise,
+it would only have printed the first line, which is just a call to
+``memcpy()``, which could be called from a thousand places in the kernel, and
+is therefore not very useful. These inlined functions would not show up in
+the stack trace above, simply because the kernel doesn't load the extra
+debugging information. This technique can of course be used with ordinary
+kernel oopses as well.
+
+In this case, it's the caller of ``memcpy()`` that is interesting, and it can be
+found in ``include/asm-generic/siginfo.h``, line 287::
+
+ 281 static inline void copy_siginfo(struct siginfo *to, struct siginfo *from)
+ 282 {
+ 283 if (from->si_code < 0)
+ 284 memcpy(to, from, sizeof(*to));
+ 285 else
+ 286 /* _sigchld is currently the largest know union member */
+ 287 memcpy(to, from, __ARCH_SI_PREAMBLE_SIZE + sizeof(from->_sifields._sigchld));
+ 288 }
+
+Since this was a read (kmemcheck usually warns about reads only, though it can
+warn about writes to unallocated or freed memory as well), it was probably the
+"from" argument which contained some uninitialized bytes. Following the chain
+of calls, we move upwards to see where "from" was allocated or initialized,
+``kernel/signal.c``, line 380::
+
+ 359 static void collect_signal(int sig, struct sigpending *list, siginfo_t *info)
+ 360 {
+ ...
+ 367 list_for_each_entry(q, &list->list, list) {
+ 368 if (q->info.si_signo == sig) {
+ 369 if (first)
+ 370 goto still_pending;
+ 371 first = q;
+ ...
+ 377 if (first) {
+ 378 still_pending:
+ 379 list_del_init(&first->list);
+ 380 copy_siginfo(info, &first->info);
+ 381 __sigqueue_free(first);
+ ...
+ 392 }
+ 393 }
+
+Here, it is ``&first->info`` that is being passed on to ``copy_siginfo()``. The
+variable ``first`` was found on a list -- passed in as the second argument to
+``collect_signal()``. We continue our journey through the stack, to figure out
+where the item on "list" was allocated or initialized. We move to line 410::
+
+ 395 static int __dequeue_signal(struct sigpending *pending, sigset_t *mask,
+ 396 siginfo_t *info)
+ 397 {
+ ...
+ 410 collect_signal(sig, pending, info);
+ ...
+ 414 }
+
+Now we need to follow the ``pending`` pointer, since that is being passed on to
+``collect_signal()`` as ``list``. At this point, we've run out of lines from the
+"addr2line" output. Not to worry, we just paste the next addresses from the
+kmemcheck stack dump, i.e.::
+
+ [<ffffffff8104f04e>] dequeue_signal+0x8e/0x170
+ [<ffffffff81050bd8>] get_signal_to_deliver+0x98/0x390
+ [<ffffffff8100b87d>] do_notify_resume+0xad/0x7d0
+ [<ffffffff8100c7b5>] int_signal+0x12/0x17
+
+ $ addr2line -e vmlinux -i ffffffff8104f04e ffffffff81050bd8 \
+ ffffffff8100b87d ffffffff8100c7b5
+ kernel/signal.c:446
+ kernel/signal.c:1806
+ arch/x86/kernel/signal.c:805
+ arch/x86/kernel/signal.c:871
+ arch/x86/kernel/entry_64.S:694
+
+Remember that since these addresses were found on the stack and not as the
+RIP value, they actually point to the _next_ instruction (they are return
+addresses). This becomes obvious when we look at the code for line 446::
+
+ 422 int dequeue_signal(struct task_struct *tsk, sigset_t *mask, siginfo_t *info)
+ 423 {
+ ...
+ 431 signr = __dequeue_signal(&tsk->signal->shared_pending,
+ 432 mask, info);
+ 433 /*
+ 434 * itimer signal ?
+ 435 *
+ 436 * itimers are process shared and we restart periodic
+ 437 * itimers in the signal delivery path to prevent DoS
+ 438 * attacks in the high resolution timer case. This is
+ 439 * compliant with the old way of self restarting
+ 440 * itimers, as the SIGALRM is a legacy signal and only
+ 441 * queued once. Changing the restart behaviour to
+ 442 * restart the timer in the signal dequeue path is
+ 443 * reducing the timer noise on heavy loaded !highres
+ 444 * systems too.
+ 445 */
+ 446 if (unlikely(signr == SIGALRM)) {
+ ...
+ 489 }
+
+So instead of looking at 446, we should be looking at 431, which is the line
+that executes just before 446. Here we see that what we are looking for is
+``&tsk->signal->shared_pending``.
+
+Our next task is now to figure out which function that puts items on this
+``shared_pending`` list. A crude, but efficient tool, is ``git grep``::
+
+ $ git grep -n 'shared_pending' kernel/
+ ...
+ kernel/signal.c:828: pending = group ? &t->signal->shared_pending : &t->pending;
+ kernel/signal.c:1339: pending = group ? &t->signal->shared_pending : &t->pending;
+ ...
+
+There were more results, but none of them were related to list operations,
+and these were the only assignments. We inspect the line numbers more closely
+and find that this is indeed where items are being added to the list::
+
+ 816 static int send_signal(int sig, struct siginfo *info, struct task_struct *t,
+ 817 int group)
+ 818 {
+ ...
+ 828 pending = group ? &t->signal->shared_pending : &t->pending;
+ ...
+ 851 q = __sigqueue_alloc(t, GFP_ATOMIC, (sig < SIGRTMIN &&
+ 852 (is_si_special(info) ||
+ 853 info->si_code >= 0)));
+ 854 if (q) {
+ 855 list_add_tail(&q->list, &pending->list);
+ ...
+ 890 }
+
+and::
+
+ 1309 int send_sigqueue(struct sigqueue *q, struct task_struct *t, int group)
+ 1310 {
+ ....
+ 1339 pending = group ? &t->signal->shared_pending : &t->pending;
+ 1340 list_add_tail(&q->list, &pending->list);
+ ....
+ 1347 }
+
+In the first case, the list element we are looking for, ``q``, is being
+returned from the function ``__sigqueue_alloc()``, which looks like an
+allocation function. Let's take a look at it::
+
+ 187 static struct sigqueue *__sigqueue_alloc(struct task_struct *t, gfp_t flags,
+ 188 int override_rlimit)
+ 189 {
+ 190 struct sigqueue *q = NULL;
+ 191 struct user_struct *user;
+ 192
+ 193 /*
+ 194 * We won't get problems with the target's UID changing under us
+ 195 * because changing it requires RCU be used, and if t != current, the
+ 196 * caller must be holding the RCU readlock (by way of a spinlock) and
+ 197 * we use RCU protection here
+ 198 */
+ 199 user = get_uid(__task_cred(t)->user);
+ 200 atomic_inc(&user->sigpending);
+ 201 if (override_rlimit ||
+ 202 atomic_read(&user->sigpending) <=
+ 203 t->signal->rlim[RLIMIT_SIGPENDING].rlim_cur)
+ 204 q = kmem_cache_alloc(sigqueue_cachep, flags);
+ 205 if (unlikely(q == NULL)) {
+ 206 atomic_dec(&user->sigpending);
+ 207 free_uid(user);
+ 208 } else {
+ 209 INIT_LIST_HEAD(&q->list);
+ 210 q->flags = 0;
+ 211 q->user = user;
+ 212 }
+ 213
+ 214 return q;
+ 215 }
+
+We see that this function initializes ``q->list``, ``q->flags``, and
+``q->user``. It seems that now is the time to look at the definition of
+``struct sigqueue``, e.g.::
+
+ 14 struct sigqueue {
+ 15 struct list_head list;
+ 16 int flags;
+ 17 siginfo_t info;
+ 18 struct user_struct *user;
+ 19 };
+
+And, you might remember, it was a ``memcpy()`` on ``&first->info`` that
+caused the warning, so this makes perfect sense. It also seems reasonable
+to assume that it is the caller of ``__sigqueue_alloc()`` that has the
+responsibility of filling out (initializing) this member.
+
+But just which fields of the struct were uninitialized? Let's look at
+kmemcheck's report again::
+
+ WARNING: kmemcheck: Caught 32-bit read from uninitialized memory (ffff88003e4a2024)
+ 80000000000000000000000000000000000000000088ffff0000000000000000
+ i i i i u u u u i i i i i i i i u u u u u u u u u u u u u u u u
+ ^
+
+These first two lines are the memory dump of the memory object itself, and
+the shadow bytemap, respectively. The memory object itself is in this case
+``&first->info``. Just beware that the start of this dump is NOT the start
+of the object itself! The position of the caret (^) corresponds with the
+address of the read (ffff88003e4a2024).
+
+The shadow bytemap dump legend is as follows:
+
+- i: initialized
+- u: uninitialized
+- a: unallocated (memory has been allocated by the slab layer, but has not
+ yet been handed off to anybody)
+- f: freed (memory has been allocated by the slab layer, but has been freed
+ by the previous owner)
+
+In order to figure out where (relative to the start of the object) the
+uninitialized memory was located, we have to look at the disassembly. For
+that, we'll need the RIP address again::
+
+ RIP: 0010:[<ffffffff8104ede8>] [<ffffffff8104ede8>] __dequeue_signal+0xc8/0x190
+
+ $ objdump -d --no-show-raw-insn vmlinux | grep -C 8 ffffffff8104ede8:
+ ffffffff8104edc8: mov %r8,0x8(%r8)
+ ffffffff8104edcc: test %r10d,%r10d
+ ffffffff8104edcf: js ffffffff8104ee88 <__dequeue_signal+0x168>
+ ffffffff8104edd5: mov %rax,%rdx
+ ffffffff8104edd8: mov $0xc,%ecx
+ ffffffff8104eddd: mov %r13,%rdi
+ ffffffff8104ede0: mov $0x30,%eax
+ ffffffff8104ede5: mov %rdx,%rsi
+ ffffffff8104ede8: rep movsl %ds:(%rsi),%es:(%rdi)
+ ffffffff8104edea: test $0x2,%al
+ ffffffff8104edec: je ffffffff8104edf0 <__dequeue_signal+0xd0>
+ ffffffff8104edee: movsw %ds:(%rsi),%es:(%rdi)
+ ffffffff8104edf0: test $0x1,%al
+ ffffffff8104edf2: je ffffffff8104edf5 <__dequeue_signal+0xd5>
+ ffffffff8104edf4: movsb %ds:(%rsi),%es:(%rdi)
+ ffffffff8104edf5: mov %r8,%rdi
+ ffffffff8104edf8: callq ffffffff8104de60 <__sigqueue_free>
+
+As expected, it's the "``rep movsl``" instruction from the ``memcpy()``
+that causes the warning. We know about ``REP MOVSL`` that it uses the register
+``RCX`` to count the number of remaining iterations. By taking a look at the
+register dump again (from the kmemcheck report), we can figure out how many
+bytes were left to copy::
+
+ RAX: 0000000000000030 RBX: ffff88003d4ea968 RCX: 0000000000000009
+
+By looking at the disassembly, we also see that ``%ecx`` is being loaded
+with the value ``$0xc`` just before (ffffffff8104edd8), so we are very
+lucky. Keep in mind that this is the number of iterations, not bytes. And
+since this is a "long" operation, we need to multiply by 4 to get the
+number of bytes. So this means that the uninitialized value was encountered
+at 4 * (0xc - 0x9) = 12 bytes from the start of the object.
+
+We can now try to figure out which field of the "``struct siginfo``" that
+was not initialized. This is the beginning of the struct::
+
+ 40 typedef struct siginfo {
+ 41 int si_signo;
+ 42 int si_errno;
+ 43 int si_code;
+ 44
+ 45 union {
+ ..
+ 92 } _sifields;
+ 93 } siginfo_t;
+
+On 64-bit, the int is 4 bytes long, so it must the union member that has
+not been initialized. We can verify this using gdb::
+
+ $ gdb vmlinux
+ ...
+ (gdb) p &((struct siginfo *) 0)->_sifields
+ $1 = (union {...} *) 0x10
+
+Actually, it seems that the union member is located at offset 0x10 -- which
+means that gcc has inserted 4 bytes of padding between the members ``si_code``
+and ``_sifields``. We can now get a fuller picture of the memory dump::
+
+ _----------------------------=> si_code
+ / _--------------------=> (padding)
+ | / _------------=> _sifields(._kill._pid)
+ | | / _----=> _sifields(._kill._uid)
+ | | | /
+ -------|-------|-------|-------|
+ 80000000000000000000000000000000000000000088ffff0000000000000000
+ i i i i u u u u i i i i i i i i u u u u u u u u u u u u u u u u
+
+This allows us to realize another important fact: ``si_code`` contains the
+value 0x80. Remember that x86 is little endian, so the first 4 bytes
+"80000000" are really the number 0x00000080. With a bit of research, we
+find that this is actually the constant ``SI_KERNEL`` defined in
+``include/asm-generic/siginfo.h``::
+
+ 144 #define SI_KERNEL 0x80 /* sent by the kernel from somewhere */
+
+This macro is used in exactly one place in the x86 kernel: In ``send_signal()``
+in ``kernel/signal.c``::
+
+ 816 static int send_signal(int sig, struct siginfo *info, struct task_struct *t,
+ 817 int group)
+ 818 {
+ ...
+ 828 pending = group ? &t->signal->shared_pending : &t->pending;
+ ...
+ 851 q = __sigqueue_alloc(t, GFP_ATOMIC, (sig < SIGRTMIN &&
+ 852 (is_si_special(info) ||
+ 853 info->si_code >= 0)));
+ 854 if (q) {
+ 855 list_add_tail(&q->list, &pending->list);
+ 856 switch ((unsigned long) info) {
+ ...
+ 865 case (unsigned long) SEND_SIG_PRIV:
+ 866 q->info.si_signo = sig;
+ 867 q->info.si_errno = 0;
+ 868 q->info.si_code = SI_KERNEL;
+ 869 q->info.si_pid = 0;
+ 870 q->info.si_uid = 0;
+ 871 break;
+ ...
+ 890 }
+
+Not only does this match with the ``.si_code`` member, it also matches the place
+we found earlier when looking for where siginfo_t objects are enqueued on the
+``shared_pending`` list.
+
+So to sum up: It seems that it is the padding introduced by the compiler
+between two struct fields that is uninitialized, and this gets reported when
+we do a ``memcpy()`` on the struct. This means that we have identified a false
+positive warning.
+
+Normally, kmemcheck will not report uninitialized accesses in ``memcpy()`` calls
+when both the source and destination addresses are tracked. (Instead, we copy
+the shadow bytemap as well). In this case, the destination address clearly
+was not tracked. We can dig a little deeper into the stack trace from above::
+
+ arch/x86/kernel/signal.c:805
+ arch/x86/kernel/signal.c:871
+ arch/x86/kernel/entry_64.S:694
+
+And we clearly see that the destination siginfo object is located on the
+stack::
+
+ 782 static void do_signal(struct pt_regs *regs)
+ 783 {
+ 784 struct k_sigaction ka;
+ 785 siginfo_t info;
+ ...
+ 804 signr = get_signal_to_deliver(&info, &ka, regs, NULL);
+ ...
+ 854 }
+
+And this ``&info`` is what eventually gets passed to ``copy_siginfo()`` as the
+destination argument.
+
+Now, even though we didn't find an actual error here, the example is still a
+good one, because it shows how one would go about to find out what the report
+was all about.
+
+
+Annotating false positives
+~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+There are a few different ways to make annotations in the source code that
+will keep kmemcheck from checking and reporting certain allocations. Here
+they are:
+
+- ``__GFP_NOTRACK_FALSE_POSITIVE``
+ This flag can be passed to ``kmalloc()`` or ``kmem_cache_alloc()``
+ (therefore also to other functions that end up calling one of
+ these) to indicate that the allocation should not be tracked
+ because it would lead to a false positive report. This is a "big
+ hammer" way of silencing kmemcheck; after all, even if the false
+ positive pertains to particular field in a struct, for example, we
+ will now lose the ability to find (real) errors in other parts of
+ the same struct.
+
+ Example::
+
+ /* No warnings will ever trigger on accessing any part of x */
+ x = kmalloc(sizeof *x, GFP_KERNEL | __GFP_NOTRACK_FALSE_POSITIVE);
+
+- ``kmemcheck_bitfield_begin(name)``/``kmemcheck_bitfield_end(name)`` and
+ ``kmemcheck_annotate_bitfield(ptr, name)``
+ The first two of these three macros can be used inside struct
+ definitions to signal, respectively, the beginning and end of a
+ bitfield. Additionally, this will assign the bitfield a name, which
+ is given as an argument to the macros.
+
+ Having used these markers, one can later use
+ kmemcheck_annotate_bitfield() at the point of allocation, to indicate
+ which parts of the allocation is part of a bitfield.
+
+ Example::
+
+ struct foo {
+ int x;
+
+ kmemcheck_bitfield_begin(flags);
+ int flag_a:1;
+ int flag_b:1;
+ kmemcheck_bitfield_end(flags);
+
+ int y;
+ };
+
+ struct foo *x = kmalloc(sizeof *x);
+
+ /* No warnings will trigger on accessing the bitfield of x */
+ kmemcheck_annotate_bitfield(x, flags);
+
+ Note that ``kmemcheck_annotate_bitfield()`` can be used even before the
+ return value of ``kmalloc()`` is checked -- in other words, passing NULL
+ as the first argument is legal (and will do nothing).
+
+
+Reporting errors
+----------------
+
+As we have seen, kmemcheck will produce false positive reports. Therefore, it
+is not very wise to blindly post kmemcheck warnings to mailing lists and
+maintainers. Instead, I encourage maintainers and developers to find errors
+in their own code. If you get a warning, you can try to work around it, try
+to figure out if it's a real error or not, or simply ignore it. Most
+developers know their own code and will quickly and efficiently determine the
+root cause of a kmemcheck report. This is therefore also the most efficient
+way to work with kmemcheck.
+
+That said, we (the kmemcheck maintainers) will always be on the lookout for
+false positives that we can annotate and silence. So whatever you find,
+please drop us a note privately! Kernel configs and steps to reproduce (if
+available) are of course a great help too.
+
+Happy hacking!
+
+
+Technical description
+---------------------
+
+kmemcheck works by marking memory pages non-present. This means that whenever
+somebody attempts to access the page, a page fault is generated. The page
+fault handler notices that the page was in fact only hidden, and so it calls
+on the kmemcheck code to make further investigations.
+
+When the investigations are completed, kmemcheck "shows" the page by marking
+it present (as it would be under normal circumstances). This way, the
+interrupted code can continue as usual.
+
+But after the instruction has been executed, we should hide the page again, so
+that we can catch the next access too! Now kmemcheck makes use of a debugging
+feature of the processor, namely single-stepping. When the processor has
+finished the one instruction that generated the memory access, a debug
+exception is raised. From here, we simply hide the page again and continue
+execution, this time with the single-stepping feature turned off.
+
+kmemcheck requires some assistance from the memory allocator in order to work.
+The memory allocator needs to
+
+ 1. Tell kmemcheck about newly allocated pages and pages that are about to
+ be freed. This allows kmemcheck to set up and tear down the shadow memory
+ for the pages in question. The shadow memory stores the status of each
+ byte in the allocation proper, e.g. whether it is initialized or
+ uninitialized.
+
+ 2. Tell kmemcheck which parts of memory should be marked uninitialized.
+ There are actually a few more states, such as "not yet allocated" and
+ "recently freed".
+
+If a slab cache is set up using the SLAB_NOTRACK flag, it will never return
+memory that can take page faults because of kmemcheck.
+
+If a slab cache is NOT set up using the SLAB_NOTRACK flag, callers can still
+request memory with the __GFP_NOTRACK or __GFP_NOTRACK_FALSE_POSITIVE flags.
+This does not prevent the page faults from occurring, however, but marks the
+object in question as being initialized so that no warnings will ever be
+produced for this object.
+
+Currently, the SLAB and SLUB allocators are supported by kmemcheck.

+Kernel Memory Leak Detector
+===========================
+
+Kmemleak provides a way of detecting possible kernel memory leaks in a
+way similar to a tracing garbage collector
+(https://en.wikipedia.org/wiki/Garbage_collection_%28computer_science%29#Tracing_garbage_collectors),
+with the difference that the orphan objects are not freed but only
+reported via /sys/kernel/debug/kmemleak. A similar method is used by the
+Valgrind tool (``memcheck --leak-check``) to detect the memory leaks in
+user-space applications.
+Kmemleak is supported on x86, arm, powerpc, sparc, sh, microblaze, ppc, mips, s390, metag and tile.
+
+Usage
+-----
+
+CONFIG_DEBUG_KMEMLEAK in "Kernel hacking" has to be enabled. A kernel
+thread scans the memory every 10 minutes (by default) and prints the
+number of new unreferenced objects found. To display the details of all
+the possible memory leaks::
+
+ # mount -t debugfs nodev /sys/kernel/debug/
+ # cat /sys/kernel/debug/kmemleak
+
+To trigger an intermediate memory scan::
+
+ # echo scan > /sys/kernel/debug/kmemleak
+
+To clear the list of all current possible memory leaks::
+
+ # echo clear > /sys/kernel/debug/kmemleak
+
+New leaks will then come up upon reading ``/sys/kernel/debug/kmemleak``
+again.
+
+Note that the orphan objects are listed in the order they were allocated
+and one object at the beginning of the list may cause other subsequent
+objects to be reported as orphan.
+
+Memory scanning parameters can be modified at run-time by writing to the
+``/sys/kernel/debug/kmemleak`` file. The following parameters are supported:
+
+- off
+ disable kmemleak (irreversible)
+- stack=on
+ enable the task stacks scanning (default)
+- stack=off
+ disable the tasks stacks scanning
+- scan=on
+ start the automatic memory scanning thread (default)
+- scan=off
+ stop the automatic memory scanning thread
+- scan=<secs>
+ set the automatic memory scanning period in seconds
+ (default 600, 0 to stop the automatic scanning)
+- scan
+ trigger a memory scan
+- clear
+ clear list of current memory leak suspects, done by
+ marking all current reported unreferenced objects grey,
+ or free all kmemleak objects if kmemleak has been disabled.
+- dump=<addr>
+ dump information about the object found at <addr>
+
+Kmemleak can also be disabled at boot-time by passing ``kmemleak=off`` on
+the kernel command line.
+
+Memory may be allocated or freed before kmemleak is initialised and
+these actions are stored in an early log buffer. The size of this buffer
+is configured via the CONFIG_DEBUG_KMEMLEAK_EARLY_LOG_SIZE option.
+
+If CONFIG_DEBUG_KMEMLEAK_DEFAULT_OFF are enabled, the kmemleak is
+disabled by default. Passing ``kmemleak=on`` on the kernel command
+line enables the function.
+
+Basic Algorithm
+---------------
+
+The memory allocations via :c:func:`kmalloc`, :c:func:`vmalloc`,
+:c:func:`kmem_cache_alloc` and
+friends are traced and the pointers, together with additional
+information like size and stack trace, are stored in a rbtree.
+The corresponding freeing function calls are tracked and the pointers
+removed from the kmemleak data structures.
+
+An allocated block of memory is considered orphan if no pointer to its
+start address or to any location inside the block can be found by
+scanning the memory (including saved registers). This means that there
+might be no way for the kernel to pass the address of the allocated
+block to a freeing function and therefore the block is considered a
+memory leak.
+
+The scanning algorithm steps:
+
+ 1. mark all objects as white (remaining white objects will later be
+ considered orphan)
+ 2. scan the memory starting with the data section and stacks, checking
+ the values against the addresses stored in the rbtree. If
+ a pointer to a white object is found, the object is added to the
+ gray list
+ 3. scan the gray objects for matching addresses (some white objects
+ can become gray and added at the end of the gray list) until the
+ gray set is finished
+ 4. the remaining white objects are considered orphan and reported via
+ /sys/kernel/debug/kmemleak
+
+Some allocated memory blocks have pointers stored in the kernel's
+internal data structures and they cannot be detected as orphans. To
+avoid this, kmemleak can also store the number of values pointing to an
+address inside the block address range that need to be found so that the
+block is not considered a leak. One example is __vmalloc().
+
+Testing specific sections with kmemleak
+---------------------------------------
+
+Upon initial bootup your /sys/kernel/debug/kmemleak output page may be
+quite extensive. This can also be the case if you have very buggy code
+when doing development. To work around these situations you can use the
+'clear' command to clear all reported unreferenced objects from the
+/sys/kernel/debug/kmemleak output. By issuing a 'scan' after a 'clear'
+you can find new unreferenced objects; this should help with testing
+specific sections of code.
+
+To test a critical section on demand with a clean kmemleak do::
+
+ # echo clear > /sys/kernel/debug/kmemleak
+ ... test your kernel or modules ...
+ # echo scan > /sys/kernel/debug/kmemleak
+
+Then as usual to get your report with::
+
+ # cat /sys/kernel/debug/kmemleak
+
+Freeing kmemleak internal objects
+---------------------------------
+
+To allow access to previously found memory leaks after kmemleak has been
+disabled by the user or due to an fatal error, internal kmemleak objects
+won't be freed when kmemleak is disabled, and those objects may occupy
+a large part of physical memory.
+
+In this situation, you may reclaim memory with::
+
+ # echo clear > /sys/kernel/debug/kmemleak
+
+Kmemleak API
+------------
+
+See the include/linux/kmemleak.h header for the functions prototype.
+
+- ``kmemleak_init`` - initialize kmemleak
+- ``kmemleak_alloc`` - notify of a memory block allocation
+- ``kmemleak_alloc_percpu`` - notify of a percpu memory block allocation
+- ``kmemleak_free`` - notify of a memory block freeing
+- ``kmemleak_free_part`` - notify of a partial memory block freeing
+- ``kmemleak_free_percpu`` - notify of a percpu memory block freeing
+- ``kmemleak_update_trace`` - update object allocation stack trace
+- ``kmemleak_not_leak`` - mark an object as not a leak
+- ``kmemleak_ignore`` - do not scan or report an object as leak
+- ``kmemleak_scan_area`` - add scan areas inside a memory block
+- ``kmemleak_no_scan`` - do not scan a memory block
+- ``kmemleak_erase`` - erase an old value in a pointer variable
+- ``kmemleak_alloc_recursive`` - as kmemleak_alloc but checks the recursiveness
+- ``kmemleak_free_recursive`` - as kmemleak_free but checks the recursiveness
+
+Dealing with false positives/negatives
+--------------------------------------
+
+The false negatives are real memory leaks (orphan objects) but not
+reported by kmemleak because values found during the memory scanning
+point to such objects. To reduce the number of false negatives, kmemleak
+provides the kmemleak_ignore, kmemleak_scan_area, kmemleak_no_scan and
+kmemleak_erase functions (see above). The task stacks also increase the
+amount of false negatives and their scanning is not enabled by default.
+
+The false positives are objects wrongly reported as being memory leaks
+(orphan). For objects known not to be leaks, kmemleak provides the
+kmemleak_not_leak function. The kmemleak_ignore could also be used if
+the memory block is known not to contain other pointers and it will no
+longer be scanned.
+
+Some of the reported leaks are only transient, especially on SMP
+systems, because of pointers temporarily stored in CPU registers or
+stacks. Kmemleak defines MSECS_MIN_AGE (defaulting to 1000) representing
+the minimum age of an object to be reported as a memory leak.
+
+Limitations and Drawbacks
+-------------------------
+
+The main drawback is the reduced performance of memory allocation and
+freeing. To avoid other penalties, the memory scanning is only performed
+when the /sys/kernel/debug/kmemleak file is read. Anyway, this tool is
+intended for debugging purposes where the performance might not be the
+most important requirement.
+
+To keep the algorithm simple, kmemleak scans for values pointing to any
+address inside a block's address range. This may lead to an increased
+number of false negatives. However, it is likely that a real memory leak
+will eventually become visible.
+
+Another source of false negatives is the data stored in non-pointer
+values. In a future version, kmemleak could only scan the pointer
+members in the allocated structures. This feature would solve many of
+the false negative cases described above.
+
+The tool can report false positives. These are cases where an allocated
+block doesn't need to be freed (some cases in the init_call functions),
+the pointer is calculated by other methods than the usual container_of
+macro or the pointer is stored in a location not scanned by kmemleak.
+
+Page allocations and ioremap are not tracked.

+Sparse
+======
+
+Sparse is a semantic checker for C programs; it can be used to find a
+number of potential problems with kernel code. See
+https://lwn.net/Articles/689907/ for an overview of sparse; this document
+contains some kernel-specific sparse information.
+
+
+Using sparse for typechecking
+-----------------------------
+
+"__bitwise" is a type attribute, so you have to do something like this::
+
+ typedef int __bitwise pm_request_t;
+
+ enum pm_request {
+ PM_SUSPEND = (__force pm_request_t) 1,
+ PM_RESUME = (__force pm_request_t) 2
+ };
+
+which makes PM_SUSPEND and PM_RESUME "bitwise" integers (the "__force" is
+there because sparse will complain about casting to/from a bitwise type,
+but in this case we really _do_ want to force the conversion). And because
+the enum values are all the same type, now "enum pm_request" will be that
+type too.
+
+And with gcc, all the "__bitwise"/"__force stuff" goes away, and it all
+ends up looking just like integers to gcc.
+
+Quite frankly, you don't need the enum there. The above all really just
+boils down to one special "int __bitwise" type.
+
+So the simpler way is to just do::
+
+ typedef int __bitwise pm_request_t;
+
+ #define PM_SUSPEND ((__force pm_request_t) 1)
+ #define PM_RESUME ((__force pm_request_t) 2)
+
+and you now have all the infrastructure needed for strict typechecking.
+
+One small note: the constant integer "0" is special. You can use a
+constant zero as a bitwise integer type without sparse ever complaining.
+This is because "bitwise" (as the name implies) was designed for making
+sure that bitwise types don't get mixed up (little-endian vs big-endian
+vs cpu-endian vs whatever), and there the constant "0" really _is_
+special.
+
+__bitwise__ - to be used for relatively compact stuff (gfp_t, etc.) that
+is mostly warning-free and is supposed to stay that way. Warnings will
+be generated without __CHECK_ENDIAN__.
+
+__bitwise - noisy stuff; in particular, __le*/__be* are that. We really
+don't want to drown in noise unless we'd explicitly asked for it.
+
+Using sparse for lock checking
+------------------------------
+
+The following macros are undefined for gcc and defined during a sparse
+run to use the "context" tracking feature of sparse, applied to
+locking. These annotations tell sparse when a lock is held, with
+regard to the annotated function's entry and exit.
+
+__must_hold - The specified lock is held on function entry and exit.
+
+__acquires - The specified lock is held on function exit, but not entry.
+
+__releases - The specified lock is held on function entry, but not exit.
+
+If the function enters and exits without the lock held, acquiring and
+releasing the lock inside the function in a balanced way, no
+annotation is needed. The tree annotations above are for cases where
+sparse would otherwise report a context imbalance.
+
+Getting sparse
+--------------
+
+You can get latest released versions from the Sparse homepage at
+https://sparse.wiki.kernel.org/index.php/Main_Page
+
+Alternatively, you can get snapshots of the latest development version
+of sparse using git to clone::
+
+ git://git.kernel.org/pub/scm/devel/sparse/sparse.git
+
+DaveJ has hourly generated tarballs of the git tree available at::
+
+ http://www.codemonkey.org.uk/projects/git-snapshots/sparse/
+
+
+Once you have it, just do::
+
+ make
+ make install
+
+as a regular user, and it will install sparse in your ~/bin directory.
+
+Using sparse
+------------
+
+Do a kernel make with "make C=1" to run sparse on all the C files that get
+recompiled, or use "make C=2" to run sparse on the files whether they need to
+be recompiled or not. The latter is a fast way to check the whole tree if you
+have already built it.
+
+The optional make variable CF can be used to pass arguments to sparse. The
+build system passes -Wbitwise to sparse automatically. To perform endianness
+checks, you may define __CHECK_ENDIAN__::
+
+ make C=2 CF="-D__CHECK_ENDIAN__"
+
+These checks are disabled by default as they generate a host of warnings.

+The Undefined Behavior Sanitizer - UBSAN
+========================================
+
+UBSAN is a runtime undefined behaviour checker.
+
+UBSAN uses compile-time instrumentation to catch undefined behavior (UB).
+Compiler inserts code that perform certain kinds of checks before operations
+that may cause UB. If check fails (i.e. UB detected) __ubsan_handle_*
+function called to print error message.
+
+GCC has that feature since 4.9.x [1_] (see ``-fsanitize=undefined`` option and
+its suboptions). GCC 5.x has more checkers implemented [2_].

+Usage
+-----
+
+To enable UBSAN configure kernel with::

+ CONFIG_UBSAN=y
+
+and to check the entire kernel::
+
+ CONFIG_UBSAN_SANITIZE_ALL=y
+
+To enable instrumentation for specific files or directories, add a line
+similar to the following to the respective kernel Makefile:
+
+- For a single file (e.g. main.o)::
+
+ UBSAN_SANITIZE_main.o := y
+
+- For all files in one directory::
+
+ UBSAN_SANITIZE := y
+
+To exclude files from being instrumented even if
+``CONFIG_UBSAN_SANITIZE_ALL=y``, use::
+
+ UBSAN_SANITIZE_main.o := n
+
+and::
+
+ UBSAN_SANITIZE := n
+
+Detection of unaligned accesses controlled through the separate option -
+CONFIG_UBSAN_ALIGNMENT. It's off by default on architectures that support
+unaligned accesses (CONFIG_HAVE_EFFICIENT_UNALIGNED_ACCESS=y). One could
+still enable it in config, just note that it will produce a lot of UBSAN
+reports.

-1: A GUIDE TO THE KERNEL DEVELOPMENT PROCESS
-
-The purpose of this document is to help developers (and their managers)
-work with the development community with a minimum of frustration. It is
-an attempt to document how this community works in a way which is
-accessible to those who are not intimately familiar with Linux kernel
-development (or, indeed, free software development in general). While
-there is some technical material here, this is very much a process-oriented
-discussion which does not require a deep knowledge of kernel programming to
-understand.
-
-
-1.1: EXECUTIVE SUMMARY
-
-The rest of this section covers the scope of the kernel development process
-and the kinds of frustrations that developers and their employers can
-encounter there. There are a great many reasons why kernel code should be
-merged into the official ("mainline") kernel, including automatic
-availability to users, community support in many forms, and the ability to
-influence the direction of kernel development. Code contributed to the
-Linux kernel must be made available under a GPL-compatible license.
-
-Section 2 introduces the development process, the kernel release cycle, and
-the mechanics of the merge window. The various phases in the patch
-development, review, and merging cycle are covered. There is some
-discussion of tools and mailing lists. Developers wanting to get started
-with kernel development are encouraged to track down and fix bugs as an
-initial exercise.
-
-Section 3 covers early-stage project planning, with an emphasis on
-involving the development community as soon as possible.
-
-Section 4 is about the coding process; several pitfalls which have been
-encountered by other developers are discussed. Some requirements for
-patches are covered, and there is an introduction to some of the tools
-which can help to ensure that kernel patches are correct.
-
-Section 5 talks about the process of posting patches for review. To be
-taken seriously by the development community, patches must be properly
-formatted and described, and they must be sent to the right place.
-Following the advice in this section should help to ensure the best
-possible reception for your work.
-
-Section 6 covers what happens after posting patches; the job is far from
-done at that point. Working with reviewers is a crucial part of the
-development process; this section offers a number of tips on how to avoid
-problems at this important stage. Developers are cautioned against
-assuming that the job is done when a patch is merged into the mainline.
-
-Section 7 introduces a couple of "advanced" topics: managing patches with
-git and reviewing patches posted by others.
-
-Section 8 concludes the document with pointers to sources for more
-information on kernel development.
-
-
-1.2: WHAT THIS DOCUMENT IS ABOUT
-
-The Linux kernel, at over 8 million lines of code and well over 1000
-contributors to each release, is one of the largest and most active free
-software projects in existence. Since its humble beginning in 1991, this
-kernel has evolved into a best-of-breed operating system component which
-runs on pocket-sized digital music players, desktop PCs, the largest
-supercomputers in existence, and all types of systems in between. It is a
-robust, efficient, and scalable solution for almost any situation.
-
-With the growth of Linux has come an increase in the number of developers
-(and companies) wishing to participate in its development. Hardware
-vendors want to ensure that Linux supports their products well, making
-those products attractive to Linux users. Embedded systems vendors, who
-use Linux as a component in an integrated product, want Linux to be as
-capable and well-suited to the task at hand as possible. Distributors and
-other software vendors who base their products on Linux have a clear
-interest in the capabilities, performance, and reliability of the Linux
-kernel. And end users, too, will often wish to change Linux to make it
-better suit their needs.
-
-One of the most compelling features of Linux is that it is accessible to
-these developers; anybody with the requisite skills can improve Linux and
-influence the direction of its development. Proprietary products cannot
-offer this kind of openness, which is a characteristic of the free software
-process. But, if anything, the kernel is even more open than most other
-free software projects. A typical three-month kernel development cycle can
-involve over 1000 developers working for more than 100 different companies
-(or for no company at all).
-
-Working with the kernel development community is not especially hard. But,
-that notwithstanding, many potential contributors have experienced
-difficulties when trying to do kernel work. The kernel community has
-evolved its own distinct ways of operating which allow it to function
-smoothly (and produce a high-quality product) in an environment where
-thousands of lines of code are being changed every day. So it is not
-surprising that Linux kernel development process differs greatly from
-proprietary development methods.
-
-The kernel's development process may come across as strange and
-intimidating to new developers, but there are good reasons and solid
-experience behind it. A developer who does not understand the kernel
-community's ways (or, worse, who tries to flout or circumvent them) will
-have a frustrating experience in store. The development community, while
-being helpful to those who are trying to learn, has little time for those
-who will not listen or who do not care about the development process.
-
-It is hoped that those who read this document will be able to avoid that
-frustrating experience. There is a lot of material here, but the effort
-involved in reading it will be repaid in short order. The development
-community is always in need of developers who will help to make the kernel
-better; the following text should help you - or those who work for you -
-join our community.

-
-1.4: THE IMPORTANCE OF GETTING CODE INTO THE MAINLINE
-
-Some companies and developers occasionally wonder why they should bother
-learning how to work with the kernel community and get their code into the
-mainline kernel (the "mainline" being the kernel maintained by Linus
-Torvalds and used as a base by Linux distributors). In the short term,
-contributing code can look like an avoidable expense; it seems easier to
-just keep the code separate and support users directly. The truth of the
-matter is that keeping code separate ("out of tree") is a false economy.
-
-As a way of illustrating the costs of out-of-tree code, here are a few
-relevant aspects of the kernel development process; most of these will be
-discussed in greater detail later in this document. Consider:
-
-- Code which has been merged into the mainline kernel is available to all
- Linux users. It will automatically be present on all distributions which
- enable it. There is no need for driver disks, downloads, or the hassles
- of supporting multiple versions of multiple distributions; it all just
- works, for the developer and for the user. Incorporation into the
- mainline solves a large number of distribution and support problems.
-
-- While kernel developers strive to maintain a stable interface to user
- space, the internal kernel API is in constant flux. The lack of a stable
- internal interface is a deliberate design decision; it allows fundamental
- improvements to be made at any time and results in higher-quality code.
- But one result of that policy is that any out-of-tree code requires
- constant upkeep if it is to work with new kernels. Maintaining
- out-of-tree code requires significant amounts of work just to keep that
- code working.
-
- Code which is in the mainline, instead, does not require this work as the
- result of a simple rule requiring any developer who makes an API change
- to also fix any code that breaks as the result of that change. So code
- which has been merged into the mainline has significantly lower
- maintenance costs.
-
-- Beyond that, code which is in the kernel will often be improved by other
- developers. Surprising results can come from empowering your user
- community and customers to improve your product.
-
-- Kernel code is subjected to review, both before and after merging into
- the mainline. No matter how strong the original developer's skills are,
- this review process invariably finds ways in which the code can be
- improved. Often review finds severe bugs and security problems. This is
- especially true for code which has been developed in a closed
- environment; such code benefits strongly from review by outside
- developers. Out-of-tree code is lower-quality code.
-
-- Participation in the development process is your way to influence the
- direction of kernel development. Users who complain from the sidelines
- are heard, but active developers have a stronger voice - and the ability
- to implement changes which make the kernel work better for their needs.
-
-- When code is maintained separately, the possibility that a third party
- will contribute a different implementation of a similar feature always
- exists. Should that happen, getting your code merged will become much
- harder - to the point of impossibility. Then you will be faced with the
- unpleasant alternatives of either (1) maintaining a nonstandard feature
- out of tree indefinitely, or (2) abandoning your code and migrating your
- users over to the in-tree version.
-
-- Contribution of code is the fundamental action which makes the whole
- process work. By contributing your code you can add new functionality to
- the kernel and provide capabilities and examples which are of use to
- other kernel developers. If you have developed code for Linux (or are
- thinking about doing so), you clearly have an interest in the continued
- success of this platform; contributing code is one of the best ways to
- help ensure that success.
-
-All of the reasoning above applies to any out-of-tree kernel code,
-including code which is distributed in proprietary, binary-only form.
-There are, however, additional factors which should be taken into account
-before considering any sort of binary-only kernel code distribution. These
-include:
-
-- The legal issues around the distribution of proprietary kernel modules
- are cloudy at best; quite a few kernel copyright holders believe that
- most binary-only modules are derived products of the kernel and that, as
- a result, their distribution is a violation of the GNU General Public
- license (about which more will be said below). Your author is not a
- lawyer, and nothing in this document can possibly be considered to be
- legal advice. The true legal status of closed-source modules can only be
- determined by the courts. But the uncertainty which haunts those modules
- is there regardless.
-
-- Binary modules greatly increase the difficulty of debugging kernel
- problems, to the point that most kernel developers will not even try. So
- the distribution of binary-only modules will make it harder for your
- users to get support from the community.
-
-- Support is also harder for distributors of binary-only modules, who must
- provide a version of the module for every distribution and every kernel
- version they wish to support. Dozens of builds of a single module can
- be required to provide reasonably comprehensive coverage, and your users
- will have to upgrade your module separately every time they upgrade their
- kernel.
-
-- Everything that was said above about code review applies doubly to
- closed-source code. Since this code is not available at all, it cannot
- have been reviewed by the community and will, beyond doubt, have serious
- problems.
-
-Makers of embedded systems, in particular, may be tempted to disregard much
-of what has been said in this section in the belief that they are shipping
-a self-contained product which uses a frozen kernel version and requires no
-more development after its release. This argument misses the value of
-widespread code review and the value of allowing your users to add
-capabilities to your product. But these products, too, have a limited
-commercial life, after which a new version must be released. At that
-point, vendors whose code is in the mainline and well maintained will be
-much better positioned to get the new product ready for market quickly.
-
-
-1.5: LICENSING
-
-Code is contributed to the Linux kernel under a number of licenses, but all
-code must be compatible with version 2 of the GNU General Public License
-(GPLv2), which is the license covering the kernel distribution as a whole.
-In practice, that means that all code contributions are covered either by
-GPLv2 (with, optionally, language allowing distribution under later
-versions of the GPL) or the three-clause BSD license. Any contributions
-which are not covered by a compatible license will not be accepted into the
-kernel.
-
-Copyright assignments are not required (or requested) for code contributed
-to the kernel. All code merged into the mainline kernel retains its
-original ownership; as a result, the kernel now has thousands of owners.
-
-One implication of this ownership structure is that any attempt to change
-the licensing of the kernel is doomed to almost certain failure. There are
-few practical scenarios where the agreement of all copyright holders could
-be obtained (or their code removed from the kernel). So, in particular,
-there is no prospect of a migration to version 3 of the GPL in the
-foreseeable future.
-
-It is imperative that all code contributed to the kernel be legitimately
-free software. For that reason, code from anonymous (or pseudonymous)
-contributors will not be accepted. All contributors are required to "sign
-off" on their code, stating that the code can be distributed with the
-kernel under the GPL. Code which has not been licensed as free software by
-its owner, or which risks creating copyright-related problems for the
-kernel (such as code which derives from reverse-engineering efforts lacking
-proper safeguards) cannot be contributed.
-
-Questions about copyright-related issues are common on Linux development
-mailing lists. Such questions will normally receive no shortage of
-answers, but one should bear in mind that the people answering those
-questions are not lawyers and cannot provide legal advice. If you have
-legal questions relating to Linux source code, there is no substitute for
-talking with a lawyer who understands this field. Relying on answers
-obtained on technical mailing lists is a risky affair.

+
+Executive summary
+-----------------
+
+The rest of this section covers the scope of the kernel development process
+and the kinds of frustrations that developers and their employers can
+encounter there. There are a great many reasons why kernel code should be
+merged into the official ("mainline") kernel, including automatic
+availability to users, community support in many forms, and the ability to
+influence the direction of kernel development. Code contributed to the
+Linux kernel must be made available under a GPL-compatible license.
+
+:ref:`development_process` introduces the development process, the kernel
+release cycle, and the mechanics of the merge window. The various phases in
+the patch development, review, and merging cycle are covered. There is some
+discussion of tools and mailing lists. Developers wanting to get started
+with kernel development are encouraged to track down and fix bugs as an
+initial exercise.
+
+:ref:`development_early_stage` covers early-stage project planning, with an
+emphasis on involving the development community as soon as possible.
+
+:ref:`development_coding` is about the coding process; several pitfalls which
+have been encountered by other developers are discussed. Some requirements for
+patches are covered, and there is an introduction to some of the tools
+which can help to ensure that kernel patches are correct.
+
+:ref:`development_posting` talks about the process of posting patches for
+review. To be taken seriously by the development community, patches must be
+properly formatted and described, and they must be sent to the right place.
+Following the advice in this section should help to ensure the best
+possible reception for your work.
+
+:ref:`development_followthrough` covers what happens after posting patches; the
+job is far from done at that point. Working with reviewers is a crucial part
+of the development process; this section offers a number of tips on how to
+avoid problems at this important stage. Developers are cautioned against
+assuming that the job is done when a patch is merged into the mainline.
+
+:ref:`development_advancedtopics` introduces a couple of "advanced" topics:
+managing patches with git and reviewing patches posted by others.
+
+:ref:`development_conclusion` concludes the document with pointers to sources
+for more information on kernel development.
+
+What this document is about
+---------------------------
+
+The Linux kernel, at over 8 million lines of code and well over 1000
+contributors to each release, is one of the largest and most active free
+software projects in existence. Since its humble beginning in 1991, this
+kernel has evolved into a best-of-breed operating system component which
+runs on pocket-sized digital music players, desktop PCs, the largest
+supercomputers in existence, and all types of systems in between. It is a
+robust, efficient, and scalable solution for almost any situation.
+
+With the growth of Linux has come an increase in the number of developers
+(and companies) wishing to participate in its development. Hardware
+vendors want to ensure that Linux supports their products well, making
+those products attractive to Linux users. Embedded systems vendors, who
+use Linux as a component in an integrated product, want Linux to be as
+capable and well-suited to the task at hand as possible. Distributors and
+other software vendors who base their products on Linux have a clear
+interest in the capabilities, performance, and reliability of the Linux
+kernel. And end users, too, will often wish to change Linux to make it
+better suit their needs.
+
+One of the most compelling features of Linux is that it is accessible to
+these developers; anybody with the requisite skills can improve Linux and
+influence the direction of its development. Proprietary products cannot
+offer this kind of openness, which is a characteristic of the free software
+process. But, if anything, the kernel is even more open than most other
+free software projects. A typical three-month kernel development cycle can
+involve over 1000 developers working for more than 100 different companies
+(or for no company at all).
+
+Working with the kernel development community is not especially hard. But,
+that notwithstanding, many potential contributors have experienced
+difficulties when trying to do kernel work. The kernel community has
+evolved its own distinct ways of operating which allow it to function
+smoothly (and produce a high-quality product) in an environment where
+thousands of lines of code are being changed every day. So it is not
+surprising that Linux kernel development process differs greatly from
+proprietary development methods.
+
+The kernel's development process may come across as strange and
+intimidating to new developers, but there are good reasons and solid
+experience behind it. A developer who does not understand the kernel
+community's ways (or, worse, who tries to flout or circumvent them) will
+have a frustrating experience in store. The development community, while
+being helpful to those who are trying to learn, has little time for those
+who will not listen or who do not care about the development process.
+
+It is hoped that those who read this document will be able to avoid that
+frustrating experience. There is a lot of material here, but the effort
+involved in reading it will be repaid in short order. The development
+community is always in need of developers who will help to make the kernel
+better; the following text should help you - or those who work for you -
+join our community.

+
+The importance of getting code into the mainline
+------------------------------------------------
+
+Some companies and developers occasionally wonder why they should bother
+learning how to work with the kernel community and get their code into the
+mainline kernel (the "mainline" being the kernel maintained by Linus
+Torvalds and used as a base by Linux distributors). In the short term,
+contributing code can look like an avoidable expense; it seems easier to
+just keep the code separate and support users directly. The truth of the
+matter is that keeping code separate ("out of tree") is a false economy.
+
+As a way of illustrating the costs of out-of-tree code, here are a few
+relevant aspects of the kernel development process; most of these will be
+discussed in greater detail later in this document. Consider:
+
+- Code which has been merged into the mainline kernel is available to all
+ Linux users. It will automatically be present on all distributions which
+ enable it. There is no need for driver disks, downloads, or the hassles
+ of supporting multiple versions of multiple distributions; it all just
+ works, for the developer and for the user. Incorporation into the
+ mainline solves a large number of distribution and support problems.
+
+- While kernel developers strive to maintain a stable interface to user
+ space, the internal kernel API is in constant flux. The lack of a stable
+ internal interface is a deliberate design decision; it allows fundamental
+ improvements to be made at any time and results in higher-quality code.
+ But one result of that policy is that any out-of-tree code requires
+ constant upkeep if it is to work with new kernels. Maintaining
+ out-of-tree code requires significant amounts of work just to keep that
+ code working.
+
+ Code which is in the mainline, instead, does not require this work as the
+ result of a simple rule requiring any developer who makes an API change
+ to also fix any code that breaks as the result of that change. So code
+ which has been merged into the mainline has significantly lower
+ maintenance costs.
+
+- Beyond that, code which is in the kernel will often be improved by other
+ developers. Surprising results can come from empowering your user
+ community and customers to improve your product.
+
+- Kernel code is subjected to review, both before and after merging into
+ the mainline. No matter how strong the original developer's skills are,
+ this review process invariably finds ways in which the code can be
+ improved. Often review finds severe bugs and security problems. This is
+ especially true for code which has been developed in a closed
+ environment; such code benefits strongly from review by outside
+ developers. Out-of-tree code is lower-quality code.
+
+- Participation in the development process is your way to influence the
+ direction of kernel development. Users who complain from the sidelines
+ are heard, but active developers have a stronger voice - and the ability
+ to implement changes which make the kernel work better for their needs.
+
+- When code is maintained separately, the possibility that a third party
+ will contribute a different implementation of a similar feature always
+ exists. Should that happen, getting your code merged will become much
+ harder - to the point of impossibility. Then you will be faced with the
+ unpleasant alternatives of either (1) maintaining a nonstandard feature
+ out of tree indefinitely, or (2) abandoning your code and migrating your
+ users over to the in-tree version.
+
+- Contribution of code is the fundamental action which makes the whole
+ process work. By contributing your code you can add new functionality to
+ the kernel and provide capabilities and examples which are of use to
+ other kernel developers. If you have developed code for Linux (or are
+ thinking about doing so), you clearly have an interest in the continued
+ success of this platform; contributing code is one of the best ways to
+ help ensure that success.
+
+All of the reasoning above applies to any out-of-tree kernel code,
+including code which is distributed in proprietary, binary-only form.
+There are, however, additional factors which should be taken into account
+before considering any sort of binary-only kernel code distribution. These
+include:
+
+- The legal issues around the distribution of proprietary kernel modules
+ are cloudy at best; quite a few kernel copyright holders believe that
+ most binary-only modules are derived products of the kernel and that, as
+ a result, their distribution is a violation of the GNU General Public
+ license (about which more will be said below). Your author is not a
+ lawyer, and nothing in this document can possibly be considered to be
+ legal advice. The true legal status of closed-source modules can only be
+ determined by the courts. But the uncertainty which haunts those modules
+ is there regardless.
+
+- Binary modules greatly increase the difficulty of debugging kernel
+ problems, to the point that most kernel developers will not even try. So
+ the distribution of binary-only modules will make it harder for your
+ users to get support from the community.
+
+- Support is also harder for distributors of binary-only modules, who must
+ provide a version of the module for every distribution and every kernel
+ version they wish to support. Dozens of builds of a single module can
+ be required to provide reasonably comprehensive coverage, and your users
+ will have to upgrade your module separately every time they upgrade their
+ kernel.
+
+- Everything that was said above about code review applies doubly to
+ closed-source code. Since this code is not available at all, it cannot
+ have been reviewed by the community and will, beyond doubt, have serious
+ problems.
+
+Makers of embedded systems, in particular, may be tempted to disregard much
+of what has been said in this section in the belief that they are shipping
+a self-contained product which uses a frozen kernel version and requires no
+more development after its release. This argument misses the value of
+widespread code review and the value of allowing your users to add
+capabilities to your product. But these products, too, have a limited
+commercial life, after which a new version must be released. At that
+point, vendors whose code is in the mainline and well maintained will be
+much better positioned to get the new product ready for market quickly.

-2: HOW THE DEVELOPMENT PROCESS WORKS
-
-Linux kernel development in the early 1990's was a pretty loose affair,
-with relatively small numbers of users and developers involved. With a
-user base in the millions and with some 2,000 developers involved over the
-course of one year, the kernel has since had to evolve a number of
-processes to keep development happening smoothly. A solid understanding of
-how the process works is required in order to be an effective part of it.
-
-
-2.1: THE BIG PICTURE
-
-The kernel developers use a loosely time-based release process, with a new
-major kernel release happening every two or three months. The recent
-release history looks like this:
-
- 2.6.38 March 14, 2011
- 2.6.37 January 4, 2011
- 2.6.36 October 20, 2010
- 2.6.35 August 1, 2010
- 2.6.34 May 15, 2010
- 2.6.33 February 24, 2010
-
-Every 2.6.x release is a major kernel release with new features, internal
-API changes, and more. A typical 2.6 release can contain nearly 10,000
-changesets with changes to several hundred thousand lines of code. 2.6 is
-thus the leading edge of Linux kernel development; the kernel uses a
-rolling development model which is continually integrating major changes.
-
-A relatively straightforward discipline is followed with regard to the
-merging of patches for each release. At the beginning of each development
-cycle, the "merge window" is said to be open. At that time, code which is
-deemed to be sufficiently stable (and which is accepted by the development
-community) is merged into the mainline kernel. The bulk of changes for a
-new development cycle (and all of the major changes) will be merged during
-this time, at a rate approaching 1,000 changes ("patches," or "changesets")
-per day.
-
-(As an aside, it is worth noting that the changes integrated during the
-merge window do not come out of thin air; they have been collected, tested,
-and staged ahead of time. How that process works will be described in
-detail later on).
-
-The merge window lasts for approximately two weeks. At the end of this
-time, Linus Torvalds will declare that the window is closed and release the
-first of the "rc" kernels. For the kernel which is destined to be 2.6.40,
-for example, the release which happens at the end of the merge window will
-be called 2.6.40-rc1. The -rc1 release is the signal that the time to
-merge new features has passed, and that the time to stabilize the next
-kernel has begun.
-
-Over the next six to ten weeks, only patches which fix problems should be
-submitted to the mainline. On occasion a more significant change will be
-allowed, but such occasions are rare; developers who try to merge new
-features outside of the merge window tend to get an unfriendly reception.
-As a general rule, if you miss the merge window for a given feature, the
-best thing to do is to wait for the next development cycle. (An occasional
-exception is made for drivers for previously-unsupported hardware; if they
-touch no in-tree code, they cannot cause regressions and should be safe to
-add at any time).
-
-As fixes make their way into the mainline, the patch rate will slow over
-time. Linus releases new -rc kernels about once a week; a normal series
-will get up to somewhere between -rc6 and -rc9 before the kernel is
-considered to be sufficiently stable and the final 2.6.x release is made.
-At that point the whole process starts over again.
-
-As an example, here is how the 2.6.38 development cycle went (all dates in
-2011):
-
- January 4 2.6.37 stable release
- January 18 2.6.38-rc1, merge window closes
- January 21 2.6.38-rc2
- February 1 2.6.38-rc3
- February 7 2.6.38-rc4
- February 15 2.6.38-rc5
- February 21 2.6.38-rc6
- March 1 2.6.38-rc7
- March 7 2.6.38-rc8
- March 14 2.6.38 stable release
-
-How do the developers decide when to close the development cycle and create
-the stable release? The most significant metric used is the list of
-regressions from previous releases. No bugs are welcome, but those which
-break systems which worked in the past are considered to be especially
-serious. For this reason, patches which cause regressions are looked upon
-unfavorably and are quite likely to be reverted during the stabilization
-period.
-
-The developers' goal is to fix all known regressions before the stable
-release is made. In the real world, this kind of perfection is hard to
-achieve; there are just too many variables in a project of this size.
-There comes a point where delaying the final release just makes the problem
-worse; the pile of changes waiting for the next merge window will grow
-larger, creating even more regressions the next time around. So most 2.6.x
-kernels go out with a handful of known regressions though, hopefully, none
-of them are serious.
-
-Once a stable release is made, its ongoing maintenance is passed off to the
-"stable team," currently consisting of Greg Kroah-Hartman. The stable team
-will release occasional updates to the stable release using the 2.6.x.y
-numbering scheme. To be considered for an update release, a patch must (1)
-fix a significant bug, and (2) already be merged into the mainline for the
-next development kernel. Kernels will typically receive stable updates for
-a little more than one development cycle past their initial release. So,
-for example, the 2.6.36 kernel's history looked like:
-
- October 10 2.6.36 stable release
- November 22 2.6.36.1
- December 9 2.6.36.2
- January 7 2.6.36.3
- February 17 2.6.36.4
-
-2.6.36.4 was the final stable update for the 2.6.36 release.
-
-Some kernels are designated "long term" kernels; they will receive support
-for a longer period. As of this writing, the current long term kernels
-and their maintainers are:
-
- 2.6.27 Willy Tarreau (Deep-frozen stable kernel)
- 2.6.32 Greg Kroah-Hartman
- 2.6.35 Andi Kleen (Embedded flag kernel)
-
-The selection of a kernel for long-term support is purely a matter of a
-maintainer having the need and the time to maintain that release. There
-are no known plans for long-term support for any specific upcoming
-release.
-
-
-2.2: THE LIFECYCLE OF A PATCH
-
-Patches do not go directly from the developer's keyboard into the mainline
-kernel. There is, instead, a somewhat involved (if somewhat informal)
-process designed to ensure that each patch is reviewed for quality and that
-each patch implements a change which is desirable to have in the mainline.
-This process can happen quickly for minor fixes, or, in the case of large
-and controversial changes, go on for years. Much developer frustration
-comes from a lack of understanding of this process or from attempts to
-circumvent it.
-
-In the hopes of reducing that frustration, this document will describe how
-a patch gets into the kernel. What follows below is an introduction which
-describes the process in a somewhat idealized way. A much more detailed
-treatment will come in later sections.
-
-The stages that a patch goes through are, generally:
-
- - Design. This is where the real requirements for the patch - and the way
- those requirements will be met - are laid out. Design work is often
- done without involving the community, but it is better to do this work
- in the open if at all possible; it can save a lot of time redesigning
- things later.
-
- - Early review. Patches are posted to the relevant mailing list, and
- developers on that list reply with any comments they may have. This
- process should turn up any major problems with a patch if all goes
- well.
-
- - Wider review. When the patch is getting close to ready for mainline
- inclusion, it should be accepted by a relevant subsystem maintainer -
- though this acceptance is not a guarantee that the patch will make it
- all the way to the mainline. The patch will show up in the maintainer's
- subsystem tree and into the -next trees (described below). When the
- process works, this step leads to more extensive review of the patch and
- the discovery of any problems resulting from the integration of this
- patch with work being done by others.
-
-- Please note that most maintainers also have day jobs, so merging
- your patch may not be their highest priority. If your patch is
- getting feedback about changes that are needed, you should either
- make those changes or justify why they should not be made. If your
- patch has no review complaints but is not being merged by its
- appropriate subsystem or driver maintainer, you should be persistent
- in updating the patch to the current kernel so that it applies cleanly
- and keep sending it for review and merging.
-
- - Merging into the mainline. Eventually, a successful patch will be
- merged into the mainline repository managed by Linus Torvalds. More
- comments and/or problems may surface at this time; it is important that
- the developer be responsive to these and fix any issues which arise.
-
- - Stable release. The number of users potentially affected by the patch
- is now large, so, once again, new problems may arise.
-
- - Long-term maintenance. While it is certainly possible for a developer
- to forget about code after merging it, that sort of behavior tends to
- leave a poor impression in the development community. Merging code
- eliminates some of the maintenance burden, in that others will fix
- problems caused by API changes. But the original developer should
- continue to take responsibility for the code if it is to remain useful
- in the longer term.
-
-One of the largest mistakes made by kernel developers (or their employers)
-is to try to cut the process down to a single "merging into the mainline"
-step. This approach invariably leads to frustration for everybody
-involved.
-
-
-2.3: HOW PATCHES GET INTO THE KERNEL
-
-There is exactly one person who can merge patches into the mainline kernel
-repository: Linus Torvalds. But, of the over 9,500 patches which went
-into the 2.6.38 kernel, only 112 (around 1.3%) were directly chosen by Linus
-himself. The kernel project has long since grown to a size where no single
-developer could possibly inspect and select every patch unassisted. The
-way the kernel developers have addressed this growth is through the use of
-a lieutenant system built around a chain of trust.
-
-The kernel code base is logically broken down into a set of subsystems:
-networking, specific architecture support, memory management, video
-devices, etc. Most subsystems have a designated maintainer, a developer
-who has overall responsibility for the code within that subsystem. These
-subsystem maintainers are the gatekeepers (in a loose way) for the portion
-of the kernel they manage; they are the ones who will (usually) accept a
-patch for inclusion into the mainline kernel.
-
-Subsystem maintainers each manage their own version of the kernel source
-tree, usually (but certainly not always) using the git source management
-tool. Tools like git (and related tools like quilt or mercurial) allow
-maintainers to track a list of patches, including authorship information
-and other metadata. At any given time, the maintainer can identify which
-patches in his or her repository are not found in the mainline.
-
-When the merge window opens, top-level maintainers will ask Linus to "pull"
-the patches they have selected for merging from their repositories. If
-Linus agrees, the stream of patches will flow up into his repository,
-becoming part of the mainline kernel. The amount of attention that Linus
-pays to specific patches received in a pull operation varies. It is clear
-that, sometimes, he looks quite closely. But, as a general rule, Linus
-trusts the subsystem maintainers to not send bad patches upstream.
-
-Subsystem maintainers, in turn, can pull patches from other maintainers.
-For example, the networking tree is built from patches which accumulated
-first in trees dedicated to network device drivers, wireless networking,
-etc. This chain of repositories can be arbitrarily long, though it rarely
-exceeds two or three links. Since each maintainer in the chain trusts
-those managing lower-level trees, this process is known as the "chain of
-trust."
-
-Clearly, in a system like this, getting patches into the kernel depends on
-finding the right maintainer. Sending patches directly to Linus is not
-normally the right way to go.
-
-
-2.4: NEXT TREES
-
-The chain of subsystem trees guides the flow of patches into the kernel,
-but it also raises an interesting question: what if somebody wants to look
-at all of the patches which are being prepared for the next merge window?
-Developers will be interested in what other changes are pending to see
-whether there are any conflicts to worry about; a patch which changes a
-core kernel function prototype, for example, will conflict with any other
-patches which use the older form of that function. Reviewers and testers
-want access to the changes in their integrated form before all of those
-changes land in the mainline kernel. One could pull changes from all of
-the interesting subsystem trees, but that would be a big and error-prone
-job.
-
-The answer comes in the form of -next trees, where subsystem trees are
-collected for testing and review. The older of these trees, maintained by
-Andrew Morton, is called "-mm" (for memory management, which is how it got
-started). The -mm tree integrates patches from a long list of subsystem
-trees; it also has some patches aimed at helping with debugging.
-
-Beyond that, -mm contains a significant collection of patches which have
-been selected by Andrew directly. These patches may have been posted on a
-mailing list, or they may apply to a part of the kernel for which there is
-no designated subsystem tree. As a result, -mm operates as a sort of
-subsystem tree of last resort; if there is no other obvious path for a
-patch into the mainline, it is likely to end up in -mm. Miscellaneous
-patches which accumulate in -mm will eventually either be forwarded on to
-an appropriate subsystem tree or be sent directly to Linus. In a typical
-development cycle, approximately 5-10% of the patches going into the
-mainline get there via -mm.
-
-The current -mm patch is available in the "mmotm" (-mm of the moment)
-directory at:
-
- http://www.ozlabs.org/~akpm/mmotm/
-
-Use of the MMOTM tree is likely to be a frustrating experience, though;
-there is a definite chance that it will not even compile.
-
-The primary tree for next-cycle patch merging is linux-next, maintained by
-Stephen Rothwell. The linux-next tree is, by design, a snapshot of what
-the mainline is expected to look like after the next merge window closes.
-Linux-next trees are announced on the linux-kernel and linux-next mailing
-lists when they are assembled; they can be downloaded from:
-
- http://www.kernel.org/pub/linux/kernel/next/
-
-Linux-next has become an integral part of the kernel development process;
-all patches merged during a given merge window should really have found
-their way into linux-next some time before the merge window opens.
-
-
-2.4.1: STAGING TREES
-
-The kernel source tree contains the drivers/staging/ directory, where
-many sub-directories for drivers or filesystems that are on their way to
-being added to the kernel tree live. They remain in drivers/staging while
-they still need more work; once complete, they can be moved into the
-kernel proper. This is a way to keep track of drivers that aren't
-up to Linux kernel coding or quality standards, but people may want to use
-them and track development.
-
-Greg Kroah-Hartman currently maintains the staging tree. Drivers that
-still need work are sent to him, with each driver having its own
-subdirectory in drivers/staging/. Along with the driver source files, a
-TODO file should be present in the directory as well. The TODO file lists
-the pending work that the driver needs for acceptance into the kernel
-proper, as well as a list of people that should be Cc'd for any patches to
-the driver. Current rules require that drivers contributed to staging
-must, at a minimum, compile properly.
-
-Staging can be a relatively easy way to get new drivers into the mainline
-where, with luck, they will come to the attention of other developers and
-improve quickly. Entry into staging is not the end of the story, though;
-code in staging which is not seeing regular progress will eventually be
-removed. Distributors also tend to be relatively reluctant to enable
-staging drivers. So staging is, at best, a stop on the way toward becoming
-a proper mainline driver.
-
-
-2.5: TOOLS
-
-As can be seen from the above text, the kernel development process depends
-heavily on the ability to herd collections of patches in various
-directions. The whole thing would not work anywhere near as well as it
-does without suitably powerful tools. Tutorials on how to use these tools
-are well beyond the scope of this document, but there is space for a few
-pointers.
-
-By far the dominant source code management system used by the kernel
-community is git. Git is one of a number of distributed version control
-systems being developed in the free software community. It is well tuned
-for kernel development, in that it performs quite well when dealing with
-large repositories and large numbers of patches. It also has a reputation
-for being difficult to learn and use, though it has gotten better over
-time. Some sort of familiarity with git is almost a requirement for kernel
-developers; even if they do not use it for their own work, they'll need git
-to keep up with what other developers (and the mainline) are doing.
-
-Git is now packaged by almost all Linux distributions. There is a home
-page at:
-
- http://git-scm.com/
-
-That page has pointers to documentation and tutorials.
-
-Among the kernel developers who do not use git, the most popular choice is
-almost certainly Mercurial:
-
- http://www.selenic.com/mercurial/
-
-Mercurial shares many features with git, but it provides an interface which
-many find easier to use.
-
-The other tool worth knowing about is Quilt:
-
- http://savannah.nongnu.org/projects/quilt/
-
-Quilt is a patch management system, rather than a source code management
-system. It does not track history over time; it is, instead, oriented
-toward tracking a specific set of changes against an evolving code base.
-Some major subsystem maintainers use quilt to manage patches intended to go
-upstream. For the management of certain kinds of trees (-mm, for example),
-quilt is the best tool for the job.
-
-
-2.6: MAILING LISTS
-
-A great deal of Linux kernel development work is done by way of mailing
-lists. It is hard to be a fully-functioning member of the community
-without joining at least one list somewhere. But Linux mailing lists also
-represent a potential hazard to developers, who risk getting buried under a
-load of electronic mail, running afoul of the conventions used on the Linux
-lists, or both.
-
-Most kernel mailing lists are run on vger.kernel.org; the master list can
-be found at:
-
- http://vger.kernel.org/vger-lists.html
-
-There are lists hosted elsewhere, though; a number of them are at
-lists.redhat.com.
-
-The core mailing list for kernel development is, of course, linux-kernel.
-This list is an intimidating place to be; volume can reach 500 messages per
-day, the amount of noise is high, the conversation can be severely
-technical, and participants are not always concerned with showing a high
-degree of politeness. But there is no other place where the kernel
-development community comes together as a whole; developers who avoid this
-list will miss important information.
-
-There are a few hints which can help with linux-kernel survival:
-
-- Have the list delivered to a separate folder, rather than your main
- mailbox. One must be able to ignore the stream for sustained periods of
- time.
-
-- Do not try to follow every conversation - nobody else does. It is
- important to filter on both the topic of interest (though note that
- long-running conversations can drift away from the original subject
- without changing the email subject line) and the people who are
- participating.
-
-- Do not feed the trolls. If somebody is trying to stir up an angry
- response, ignore them.
-
-- When responding to linux-kernel email (or that on other lists) preserve
- the Cc: header for all involved. In the absence of a strong reason (such
- as an explicit request), you should never remove recipients. Always make
- sure that the person you are responding to is in the Cc: list. This
- convention also makes it unnecessary to explicitly ask to be copied on
- replies to your postings.
-
-- Search the list archives (and the net as a whole) before asking
- questions. Some developers can get impatient with people who clearly
- have not done their homework.
-
-- Avoid top-posting (the practice of putting your answer above the quoted
- text you are responding to). It makes your response harder to read and
- makes a poor impression.
-
-- Ask on the correct mailing list. Linux-kernel may be the general meeting
- point, but it is not the best place to find developers from all
- subsystems.
-
-The last point - finding the correct mailing list - is a common place for
-beginning developers to go wrong. Somebody who asks a networking-related
-question on linux-kernel will almost certainly receive a polite suggestion
-to ask on the netdev list instead, as that is the list frequented by most
-networking developers. Other lists exist for the SCSI, video4linux, IDE,
-filesystem, etc. subsystems. The best place to look for mailing lists is
-in the MAINTAINERS file packaged with the kernel source.
-
-
-2.7: GETTING STARTED WITH KERNEL DEVELOPMENT
-
-Questions about how to get started with the kernel development process are
-common - from both individuals and companies. Equally common are missteps
-which make the beginning of the relationship harder than it has to be.
-
-Companies often look to hire well-known developers to get a development
-group started. This can, in fact, be an effective technique. But it also
-tends to be expensive and does not do much to grow the pool of experienced
-kernel developers. It is possible to bring in-house developers up to speed
-on Linux kernel development, given the investment of a bit of time. Taking
-this time can endow an employer with a group of developers who understand
-the kernel and the company both, and who can help to train others as well.
-Over the medium term, this is often the more profitable approach.
-
-Individual developers are often, understandably, at a loss for a place to
-start. Beginning with a large project can be intimidating; one often wants
-to test the waters with something smaller first. This is the point where
-some developers jump into the creation of patches fixing spelling errors or
-minor coding style issues. Unfortunately, such patches create a level of
-noise which is distracting for the development community as a whole, so,
-increasingly, they are looked down upon. New developers wishing to
-introduce themselves to the community will not get the sort of reception
-they wish for by these means.
-
-Andrew Morton gives this advice for aspiring kernel developers
-
- The #1 project for all kernel beginners should surely be "make sure
- that the kernel runs perfectly at all times on all machines which
- you can lay your hands on". Usually the way to do this is to work
- with others on getting things fixed up (this can require
- persistence!) but that's fine - it's a part of kernel development.
-
-(http://lwn.net/Articles/283982/).
-
-In the absence of obvious problems to fix, developers are advised to look
-at the current lists of regressions and open bugs in general. There is
-never any shortage of issues in need of fixing; by addressing these issues,
-developers will gain experience with the process while, at the same time,
-building respect with the rest of the development community.

+
+How the development process works
+=================================
+
+Linux kernel development in the early 1990's was a pretty loose affair,
+with relatively small numbers of users and developers involved. With a
+user base in the millions and with some 2,000 developers involved over the
+course of one year, the kernel has since had to evolve a number of
+processes to keep development happening smoothly. A solid understanding of
+how the process works is required in order to be an effective part of it.
+
+The big picture
+---------------
+
+The kernel developers use a loosely time-based release process, with a new
+major kernel release happening every two or three months. The recent
+release history looks like this:
+
+ ====== =================
+ 2.6.38 March 14, 2011
+ 2.6.37 January 4, 2011
+ 2.6.36 October 20, 2010
+ 2.6.35 August 1, 2010
+ 2.6.34 May 15, 2010
+ 2.6.33 February 24, 2010
+ ====== =================
+
+Every 2.6.x release is a major kernel release with new features, internal
+API changes, and more. A typical 2.6 release can contain nearly 10,000
+changesets with changes to several hundred thousand lines of code. 2.6 is
+thus the leading edge of Linux kernel development; the kernel uses a
+rolling development model which is continually integrating major changes.
+
+A relatively straightforward discipline is followed with regard to the
+merging of patches for each release. At the beginning of each development
+cycle, the "merge window" is said to be open. At that time, code which is
+deemed to be sufficiently stable (and which is accepted by the development
+community) is merged into the mainline kernel. The bulk of changes for a
+new development cycle (and all of the major changes) will be merged during
+this time, at a rate approaching 1,000 changes ("patches," or "changesets")
+per day.
+
+(As an aside, it is worth noting that the changes integrated during the
+merge window do not come out of thin air; they have been collected, tested,
+and staged ahead of time. How that process works will be described in
+detail later on).
+
+The merge window lasts for approximately two weeks. At the end of this
+time, Linus Torvalds will declare that the window is closed and release the
+first of the "rc" kernels. For the kernel which is destined to be 2.6.40,
+for example, the release which happens at the end of the merge window will
+be called 2.6.40-rc1. The -rc1 release is the signal that the time to
+merge new features has passed, and that the time to stabilize the next
+kernel has begun.
+
+Over the next six to ten weeks, only patches which fix problems should be
+submitted to the mainline. On occasion a more significant change will be
+allowed, but such occasions are rare; developers who try to merge new
+features outside of the merge window tend to get an unfriendly reception.
+As a general rule, if you miss the merge window for a given feature, the
+best thing to do is to wait for the next development cycle. (An occasional
+exception is made for drivers for previously-unsupported hardware; if they
+touch no in-tree code, they cannot cause regressions and should be safe to
+add at any time).
+
+As fixes make their way into the mainline, the patch rate will slow over
+time. Linus releases new -rc kernels about once a week; a normal series
+will get up to somewhere between -rc6 and -rc9 before the kernel is
+considered to be sufficiently stable and the final 2.6.x release is made.
+At that point the whole process starts over again.
+
+As an example, here is how the 2.6.38 development cycle went (all dates in
+2011):
+
+ ============== ===============================
+ January 4 2.6.37 stable release
+ January 18 2.6.38-rc1, merge window closes
+ January 21 2.6.38-rc2
+ February 1 2.6.38-rc3
+ February 7 2.6.38-rc4
+ February 15 2.6.38-rc5
+ February 21 2.6.38-rc6
+ March 1 2.6.38-rc7
+ March 7 2.6.38-rc8
+ March 14 2.6.38 stable release
+ ============== ===============================
+
+How do the developers decide when to close the development cycle and create
+the stable release? The most significant metric used is the list of
+regressions from previous releases. No bugs are welcome, but those which
+break systems which worked in the past are considered to be especially
+serious. For this reason, patches which cause regressions are looked upon
+unfavorably and are quite likely to be reverted during the stabilization
+period.
+
+The developers' goal is to fix all known regressions before the stable
+release is made. In the real world, this kind of perfection is hard to
+achieve; there are just too many variables in a project of this size.
+There comes a point where delaying the final release just makes the problem
+worse; the pile of changes waiting for the next merge window will grow
+larger, creating even more regressions the next time around. So most 2.6.x
+kernels go out with a handful of known regressions though, hopefully, none
+of them are serious.
+
+Once a stable release is made, its ongoing maintenance is passed off to the
+"stable team," currently consisting of Greg Kroah-Hartman. The stable team
+will release occasional updates to the stable release using the 2.6.x.y
+numbering scheme. To be considered for an update release, a patch must (1)
+fix a significant bug, and (2) already be merged into the mainline for the
+next development kernel. Kernels will typically receive stable updates for
+a little more than one development cycle past their initial release. So,
+for example, the 2.6.36 kernel's history looked like:
+
+ ============== ===============================
+ October 10 2.6.36 stable release
+ November 22 2.6.36.1
+ December 9 2.6.36.2
+ January 7 2.6.36.3
+ February 17 2.6.36.4
+ ============== ===============================
+
+2.6.36.4 was the final stable update for the 2.6.36 release.
+
+Some kernels are designated "long term" kernels; they will receive support
+for a longer period. As of this writing, the current long term kernels
+and their maintainers are:
+
+ ====== ====================== ===========================
+ 2.6.27 Willy Tarreau (Deep-frozen stable kernel)
+ 2.6.32 Greg Kroah-Hartman
+ 2.6.35 Andi Kleen (Embedded flag kernel)
+ ====== ====================== ===========================
+
+The selection of a kernel for long-term support is purely a matter of a
+maintainer having the need and the time to maintain that release. There
+are no known plans for long-term support for any specific upcoming
+release.
+
+
+The lifecycle of a patch
+------------------------
+
+Patches do not go directly from the developer's keyboard into the mainline
+kernel. There is, instead, a somewhat involved (if somewhat informal)
+process designed to ensure that each patch is reviewed for quality and that
+each patch implements a change which is desirable to have in the mainline.
+This process can happen quickly for minor fixes, or, in the case of large
+and controversial changes, go on for years. Much developer frustration
+comes from a lack of understanding of this process or from attempts to
+circumvent it.
+
+In the hopes of reducing that frustration, this document will describe how
+a patch gets into the kernel. What follows below is an introduction which
+describes the process in a somewhat idealized way. A much more detailed
+treatment will come in later sections.
+
+The stages that a patch goes through are, generally:
+
+ - Design. This is where the real requirements for the patch - and the way
+ those requirements will be met - are laid out. Design work is often
+ done without involving the community, but it is better to do this work
+ in the open if at all possible; it can save a lot of time redesigning
+ things later.
+
+ - Early review. Patches are posted to the relevant mailing list, and
+ developers on that list reply with any comments they may have. This
+ process should turn up any major problems with a patch if all goes
+ well.
+
+ - Wider review. When the patch is getting close to ready for mainline
+ inclusion, it should be accepted by a relevant subsystem maintainer -
+ though this acceptance is not a guarantee that the patch will make it
+ all the way to the mainline. The patch will show up in the maintainer's
+ subsystem tree and into the -next trees (described below). When the
+ process works, this step leads to more extensive review of the patch and
+ the discovery of any problems resulting from the integration of this
+ patch with work being done by others.
+
+- Please note that most maintainers also have day jobs, so merging
+ your patch may not be their highest priority. If your patch is
+ getting feedback about changes that are needed, you should either
+ make those changes or justify why they should not be made. If your
+ patch has no review complaints but is not being merged by its
+ appropriate subsystem or driver maintainer, you should be persistent
+ in updating the patch to the current kernel so that it applies cleanly
+ and keep sending it for review and merging.
+
+ - Merging into the mainline. Eventually, a successful patch will be
+ merged into the mainline repository managed by Linus Torvalds. More
+ comments and/or problems may surface at this time; it is important that
+ the developer be responsive to these and fix any issues which arise.
+
+ - Stable release. The number of users potentially affected by the patch
+ is now large, so, once again, new problems may arise.
+
+ - Long-term maintenance. While it is certainly possible for a developer
+ to forget about code after merging it, that sort of behavior tends to
+ leave a poor impression in the development community. Merging code
+ eliminates some of the maintenance burden, in that others will fix
+ problems caused by API changes. But the original developer should
+ continue to take responsibility for the code if it is to remain useful
+ in the longer term.
+
+One of the largest mistakes made by kernel developers (or their employers)
+is to try to cut the process down to a single "merging into the mainline"
+step. This approach invariably leads to frustration for everybody
+involved.
+
+How patches get into the Kernel
+-------------------------------
+
+There is exactly one person who can merge patches into the mainline kernel
+repository: Linus Torvalds. But, of the over 9,500 patches which went
+into the 2.6.38 kernel, only 112 (around 1.3%) were directly chosen by Linus
+himself. The kernel project has long since grown to a size where no single
+developer could possibly inspect and select every patch unassisted. The
+way the kernel developers have addressed this growth is through the use of
+a lieutenant system built around a chain of trust.
+
+The kernel code base is logically broken down into a set of subsystems:
+networking, specific architecture support, memory management, video
+devices, etc. Most subsystems have a designated maintainer, a developer
+who has overall responsibility for the code within that subsystem. These
+subsystem maintainers are the gatekeepers (in a loose way) for the portion
+of the kernel they manage; they are the ones who will (usually) accept a
+patch for inclusion into the mainline kernel.
+
+Subsystem maintainers each manage their own version of the kernel source
+tree, usually (but certainly not always) using the git source management
+tool. Tools like git (and related tools like quilt or mercurial) allow
+maintainers to track a list of patches, including authorship information
+and other metadata. At any given time, the maintainer can identify which
+patches in his or her repository are not found in the mainline.
+
+When the merge window opens, top-level maintainers will ask Linus to "pull"
+the patches they have selected for merging from their repositories. If
+Linus agrees, the stream of patches will flow up into his repository,
+becoming part of the mainline kernel. The amount of attention that Linus
+pays to specific patches received in a pull operation varies. It is clear
+that, sometimes, he looks quite closely. But, as a general rule, Linus
+trusts the subsystem maintainers to not send bad patches upstream.
+
+Subsystem maintainers, in turn, can pull patches from other maintainers.
+For example, the networking tree is built from patches which accumulated
+first in trees dedicated to network device drivers, wireless networking,
+etc. This chain of repositories can be arbitrarily long, though it rarely
+exceeds two or three links. Since each maintainer in the chain trusts
+those managing lower-level trees, this process is known as the "chain of
+trust."
+
+Clearly, in a system like this, getting patches into the kernel depends on
+finding the right maintainer. Sending patches directly to Linus is not
+normally the right way to go.
+
+
+Next trees
+----------
+
+The chain of subsystem trees guides the flow of patches into the kernel,
+but it also raises an interesting question: what if somebody wants to look
+at all of the patches which are being prepared for the next merge window?
+Developers will be interested in what other changes are pending to see
+whether there are any conflicts to worry about; a patch which changes a
+core kernel function prototype, for example, will conflict with any other
+patches which use the older form of that function. Reviewers and testers
+want access to the changes in their integrated form before all of those
+changes land in the mainline kernel. One could pull changes from all of
+the interesting subsystem trees, but that would be a big and error-prone
+job.
+
+The answer comes in the form of -next trees, where subsystem trees are
+collected for testing and review. The older of these trees, maintained by
+Andrew Morton, is called "-mm" (for memory management, which is how it got
+started). The -mm tree integrates patches from a long list of subsystem
+trees; it also has some patches aimed at helping with debugging.
+
+Beyond that, -mm contains a significant collection of patches which have
+been selected by Andrew directly. These patches may have been posted on a
+mailing list, or they may apply to a part of the kernel for which there is
+no designated subsystem tree. As a result, -mm operates as a sort of
+subsystem tree of last resort; if there is no other obvious path for a
+patch into the mainline, it is likely to end up in -mm. Miscellaneous
+patches which accumulate in -mm will eventually either be forwarded on to
+an appropriate subsystem tree or be sent directly to Linus. In a typical
+development cycle, approximately 5-10% of the patches going into the
+mainline get there via -mm.
+
+The current -mm patch is available in the "mmotm" (-mm of the moment)
+directory at:
+
+ http://www.ozlabs.org/~akpm/mmotm/
+
+Use of the MMOTM tree is likely to be a frustrating experience, though;
+there is a definite chance that it will not even compile.
+
+The primary tree for next-cycle patch merging is linux-next, maintained by
+Stephen Rothwell. The linux-next tree is, by design, a snapshot of what
+the mainline is expected to look like after the next merge window closes.
+Linux-next trees are announced on the linux-kernel and linux-next mailing
+lists when they are assembled; they can be downloaded from:
+
+ http://www.kernel.org/pub/linux/kernel/next/
+
+Linux-next has become an integral part of the kernel development process;
+all patches merged during a given merge window should really have found
+their way into linux-next some time before the merge window opens.
+
+
+Staging trees
+-------------
+
+The kernel source tree contains the drivers/staging/ directory, where
+many sub-directories for drivers or filesystems that are on their way to
+being added to the kernel tree live. They remain in drivers/staging while
+they still need more work; once complete, they can be moved into the
+kernel proper. This is a way to keep track of drivers that aren't
+up to Linux kernel coding or quality standards, but people may want to use
+them and track development.
+
+Greg Kroah-Hartman currently maintains the staging tree. Drivers that
+still need work are sent to him, with each driver having its own
+subdirectory in drivers/staging/. Along with the driver source files, a
+TODO file should be present in the directory as well. The TODO file lists
+the pending work that the driver needs for acceptance into the kernel
+proper, as well as a list of people that should be Cc'd for any patches to
+the driver. Current rules require that drivers contributed to staging
+must, at a minimum, compile properly.
+
+Staging can be a relatively easy way to get new drivers into the mainline
+where, with luck, they will come to the attention of other developers and
+improve quickly. Entry into staging is not the end of the story, though;
+code in staging which is not seeing regular progress will eventually be
+removed. Distributors also tend to be relatively reluctant to enable
+staging drivers. So staging is, at best, a stop on the way toward becoming
+a proper mainline driver.

+- Have the list delivered to a separate folder, rather than your main
+ mailbox. One must be able to ignore the stream for sustained periods of
+ time.
+
+- Do not try to follow every conversation - nobody else does. It is
+ important to filter on both the topic of interest (though note that
+ long-running conversations can drift away from the original subject
+ without changing the email subject line) and the people who are
+ participating.
+
+- Do not feed the trolls. If somebody is trying to stir up an angry
+ response, ignore them.
+
+- When responding to linux-kernel email (or that on other lists) preserve
+ the Cc: header for all involved. In the absence of a strong reason (such
+ as an explicit request), you should never remove recipients. Always make
+ sure that the person you are responding to is in the Cc: list. This
+ convention also makes it unnecessary to explicitly ask to be copied on
+ replies to your postings.
+
+- Search the list archives (and the net as a whole) before asking
+ questions. Some developers can get impatient with people who clearly
+ have not done their homework.
+
+- Avoid top-posting (the practice of putting your answer above the quoted
+ text you are responding to). It makes your response harder to read and
+ makes a poor impression.
+
+- Ask on the correct mailing list. Linux-kernel may be the general meeting
+ point, but it is not the best place to find developers from all
+ subsystems.
+
+The last point - finding the correct mailing list - is a common place for
+beginning developers to go wrong. Somebody who asks a networking-related
+question on linux-kernel will almost certainly receive a polite suggestion
+to ask on the netdev list instead, as that is the list frequented by most
+networking developers. Other lists exist for the SCSI, video4linux, IDE,
+filesystem, etc. subsystems. The best place to look for mailing lists is
+in the MAINTAINERS file packaged with the kernel source.
+
+
+Getting started with Kernel development
+---------------------------------------
+
+Questions about how to get started with the kernel development process are
+common - from both individuals and companies. Equally common are missteps
+which make the beginning of the relationship harder than it has to be.
+
+Companies often look to hire well-known developers to get a development
+group started. This can, in fact, be an effective technique. But it also
+tends to be expensive and does not do much to grow the pool of experienced
+kernel developers. It is possible to bring in-house developers up to speed
+on Linux kernel development, given the investment of a bit of time. Taking
+this time can endow an employer with a group of developers who understand
+the kernel and the company both, and who can help to train others as well.
+Over the medium term, this is often the more profitable approach.
+
+Individual developers are often, understandably, at a loss for a place to
+start. Beginning with a large project can be intimidating; one often wants
+to test the waters with something smaller first. This is the point where
+some developers jump into the creation of patches fixing spelling errors or
+minor coding style issues. Unfortunately, such patches create a level of
+noise which is distracting for the development community as a whole, so,
+increasingly, they are looked down upon. New developers wishing to
+introduce themselves to the community will not get the sort of reception
+they wish for by these means.
+
+Andrew Morton gives this advice for aspiring kernel developers
+
+::
+
+ The #1 project for all kernel beginners should surely be "make sure
+ that the kernel runs perfectly at all times on all machines which
+ you can lay your hands on". Usually the way to do this is to work
+ with others on getting things fixed up (this can require
+ persistence!) but that's fine - it's a part of kernel development.
+
+(http://lwn.net/Articles/283982/).
+
+In the absence of obvious problems to fix, developers are advised to look
+at the current lists of regressions and open bugs in general. There is
+never any shortage of issues in need of fixing; by addressing these issues,
+developers will gain experience with the process while, at the same time,
+building respect with the rest of the development community.

-3: EARLY-STAGE PLANNING
-
-When contemplating a Linux kernel development project, it can be tempting
-to jump right in and start coding. As with any significant project,
-though, much of the groundwork for success is best laid before the first
-line of code is written. Some time spent in early planning and
-communication can save far more time later on.
-
-
-3.1: SPECIFYING THE PROBLEM
-
-Like any engineering project, a successful kernel enhancement starts with a
-clear description of the problem to be solved. In some cases, this step is
-easy: when a driver is needed for a specific piece of hardware, for
-example. In others, though, it is tempting to confuse the real problem
-with the proposed solution, and that can lead to difficulties.
-
-Consider an example: some years ago, developers working with Linux audio
-sought a way to run applications without dropouts or other artifacts caused
-by excessive latency in the system. The solution they arrived at was a
-kernel module intended to hook into the Linux Security Module (LSM)
-framework; this module could be configured to give specific applications
-access to the realtime scheduler. This module was implemented and sent to
-the linux-kernel mailing list, where it immediately ran into problems.
-
-To the audio developers, this security module was sufficient to solve their
-immediate problem. To the wider kernel community, though, it was seen as a
-misuse of the LSM framework (which is not intended to confer privileges
-onto processes which they would not otherwise have) and a risk to system
-stability. Their preferred solutions involved realtime scheduling access
-via the rlimit mechanism for the short term, and ongoing latency reduction
-work in the long term.
-
-The audio community, however, could not see past the particular solution
-they had implemented; they were unwilling to accept alternatives. The
-resulting disagreement left those developers feeling disillusioned with the
-entire kernel development process; one of them went back to an audio list
-and posted this:
-
- There are a number of very good Linux kernel developers, but they
- tend to get outshouted by a large crowd of arrogant fools. Trying
- to communicate user requirements to these people is a waste of
- time. They are much too "intelligent" to listen to lesser mortals.
-
-(http://lwn.net/Articles/131776/).
-
-The reality of the situation was different; the kernel developers were far
-more concerned about system stability, long-term maintenance, and finding
-the right solution to the problem than they were with a specific module.
-The moral of the story is to focus on the problem - not a specific solution
-- and to discuss it with the development community before investing in the
-creation of a body of code.
-
-So, when contemplating a kernel development project, one should obtain
-answers to a short set of questions:
-
- - What, exactly, is the problem which needs to be solved?
-
- - Who are the users affected by this problem? Which use cases should the
- solution address?
-
- - How does the kernel fall short in addressing that problem now?
-
-Only then does it make sense to start considering possible solutions.
-
-
-3.2: EARLY DISCUSSION
-
-When planning a kernel development project, it makes great sense to hold
-discussions with the community before launching into implementation. Early
-communication can save time and trouble in a number of ways:
-
- - It may well be that the problem is addressed by the kernel in ways which
- you have not understood. The Linux kernel is large and has a number of
- features and capabilities which are not immediately obvious. Not all
- kernel capabilities are documented as well as one might like, and it is
- easy to miss things. Your author has seen the posting of a complete
- driver which duplicated an existing driver that the new author had been
- unaware of. Code which reinvents existing wheels is not only wasteful;
- it will also not be accepted into the mainline kernel.
-
- - There may be elements of the proposed solution which will not be
- acceptable for mainline merging. It is better to find out about
- problems like this before writing the code.
-
- - It's entirely possible that other developers have thought about the
- problem; they may have ideas for a better solution, and may be willing
- to help in the creation of that solution.
-
-Years of experience with the kernel development community have taught a
-clear lesson: kernel code which is designed and developed behind closed
-doors invariably has problems which are only revealed when the code is
-released into the community. Sometimes these problems are severe,
-requiring months or years of effort before the code can be brought up to
-the kernel community's standards. Some examples include:
-
- - The Devicescape network stack was designed and implemented for
- single-processor systems. It could not be merged into the mainline
- until it was made suitable for multiprocessor systems. Retrofitting
- locking and such into code is a difficult task; as a result, the merging
- of this code (now called mac80211) was delayed for over a year.
-
- - The Reiser4 filesystem included a number of capabilities which, in the
- core kernel developers' opinion, should have been implemented in the
- virtual filesystem layer instead. It also included features which could
- not easily be implemented without exposing the system to user-caused
- deadlocks. The late revelation of these problems - and refusal to
- address some of them - has caused Reiser4 to stay out of the mainline
- kernel.
-
- - The AppArmor security module made use of internal virtual filesystem
- data structures in ways which were considered to be unsafe and
- unreliable. This concern (among others) kept AppArmor out of the
- mainline for years.
-
-In each of these cases, a great deal of pain and extra work could have been
-avoided with some early discussion with the kernel developers.
-
-
-3.3: WHO DO YOU TALK TO?
-
-When developers decide to take their plans public, the next question will
-be: where do we start? The answer is to find the right mailing list(s) and
-the right maintainer. For mailing lists, the best approach is to look in
-the MAINTAINERS file for a relevant place to post. If there is a suitable
-subsystem list, posting there is often preferable to posting on
-linux-kernel; you are more likely to reach developers with expertise in the
-relevant subsystem and the environment may be more supportive.
-
-Finding maintainers can be a bit harder. Again, the MAINTAINERS file is
-the place to start. That file tends to not always be up to date, though,
-and not all subsystems are represented there. The person listed in the
-MAINTAINERS file may, in fact, not be the person who is actually acting in
-that role currently. So, when there is doubt about who to contact, a
-useful trick is to use git (and "git log" in particular) to see who is
-currently active within the subsystem of interest. Look at who is writing
-patches, and who, if anybody, is attaching Signed-off-by lines to those
-patches. Those are the people who will be best placed to help with a new
-development project.
-
-The task of finding the right maintainer is sometimes challenging enough
-that the kernel developers have added a script to ease the process:
-
- .../scripts/get_maintainer.pl
-
-This script will return the current maintainer(s) for a given file or
-directory when given the "-f" option. If passed a patch on the
-command line, it will list the maintainers who should probably receive
-copies of the patch. There are a number of options regulating how hard
-get_maintainer.pl will search for maintainers; please be careful about
-using the more aggressive options as you may end up including developers
-who have no real interest in the code you are modifying.
-
-If all else fails, talking to Andrew Morton can be an effective way to
-track down a maintainer for a specific piece of code.
-
-
-3.4: WHEN TO POST?
-
-If possible, posting your plans during the early stages can only be
-helpful. Describe the problem being solved and any plans that have been
-made on how the implementation will be done. Any information you can
-provide can help the development community provide useful input on the
-project.
-
-One discouraging thing which can happen at this stage is not a hostile
-reaction, but, instead, little or no reaction at all. The sad truth of the
-matter is (1) kernel developers tend to be busy, (2) there is no shortage
-of people with grand plans and little code (or even prospect of code) to
-back them up, and (3) nobody is obligated to review or comment on ideas
-posted by others. Beyond that, high-level designs often hide problems
-which are only reviewed when somebody actually tries to implement those
-designs; for that reason, kernel developers would rather see the code.
-
-If a request-for-comments posting yields little in the way of comments, do
-not assume that it means there is no interest in the project.
-Unfortunately, you also cannot assume that there are no problems with your
-idea. The best thing to do in this situation is to proceed, keeping the
-community informed as you go.
-
-
-3.5: GETTING OFFICIAL BUY-IN
-
-If your work is being done in a corporate environment - as most Linux
-kernel work is - you must, obviously, have permission from suitably
-empowered managers before you can post your company's plans or code to a
-public mailing list. The posting of code which has not been cleared for
-release under a GPL-compatible license can be especially problematic; the
-sooner that a company's management and legal staff can agree on the posting
-of a kernel development project, the better off everybody involved will be.
-
-Some readers may be thinking at this point that their kernel work is
-intended to support a product which does not yet have an officially
-acknowledged existence. Revealing their employer's plans on a public
-mailing list may not be a viable option. In cases like this, it is worth
-considering whether the secrecy is really necessary; there is often no real
-need to keep development plans behind closed doors.
-
-That said, there are also cases where a company legitimately cannot
-disclose its plans early in the development process. Companies with
-experienced kernel developers may choose to proceed in an open-loop manner
-on the assumption that they will be able to avoid serious integration
-problems later. For companies without that sort of in-house expertise, the
-best option is often to hire an outside developer to review the plans under
-a non-disclosure agreement. The Linux Foundation operates an NDA program
-designed to help with this sort of situation; more information can be found
-at:
-
- http://www.linuxfoundation.org/en/NDA_program
-
-This kind of review is often enough to avoid serious problems later on
-without requiring public disclosure of the project.

-4: GETTING THE CODE RIGHT
-
-While there is much to be said for a solid and community-oriented design
-process, the proof of any kernel development project is in the resulting
-code. It is the code which will be examined by other developers and merged
-(or not) into the mainline tree. So it is the quality of this code which
-will determine the ultimate success of the project.
-
-This section will examine the coding process. We'll start with a look at a
-number of ways in which kernel developers can go wrong. Then the focus
-will shift toward doing things right and the tools which can help in that
-quest.
-
-
-4.1: PITFALLS
-
-* Coding style
-
-The kernel has long had a standard coding style, described in
-Documentation/CodingStyle. For much of that time, the policies described
-in that file were taken as being, at most, advisory. As a result, there is
-a substantial amount of code in the kernel which does not meet the coding
-style guidelines. The presence of that code leads to two independent
-hazards for kernel developers.
-
-The first of these is to believe that the kernel coding standards do not
-matter and are not enforced. The truth of the matter is that adding new
-code to the kernel is very difficult if that code is not coded according to
-the standard; many developers will request that the code be reformatted
-before they will even review it. A code base as large as the kernel
-requires some uniformity of code to make it possible for developers to
-quickly understand any part of it. So there is no longer room for
-strangely-formatted code.
-
-Occasionally, the kernel's coding style will run into conflict with an
-employer's mandated style. In such cases, the kernel's style will have to
-win before the code can be merged. Putting code into the kernel means
-giving up a degree of control in a number of ways - including control over
-how the code is formatted.
-
-The other trap is to assume that code which is already in the kernel is
-urgently in need of coding style fixes. Developers may start to generate
-reformatting patches as a way of gaining familiarity with the process, or
-as a way of getting their name into the kernel changelogs - or both. But
-pure coding style fixes are seen as noise by the development community;
-they tend to get a chilly reception. So this type of patch is best
-avoided. It is natural to fix the style of a piece of code while working
-on it for other reasons, but coding style changes should not be made for
-their own sake.
-
-The coding style document also should not be read as an absolute law which
-can never be transgressed. If there is a good reason to go against the
-style (a line which becomes far less readable if split to fit within the
-80-column limit, for example), just do it.
-
-
-* Abstraction layers
-
-Computer Science professors teach students to make extensive use of
-abstraction layers in the name of flexibility and information hiding.
-Certainly the kernel makes extensive use of abstraction; no project
-involving several million lines of code could do otherwise and survive.
-But experience has shown that excessive or premature abstraction can be
-just as harmful as premature optimization. Abstraction should be used to
-the level required and no further.
-
-At a simple level, consider a function which has an argument which is
-always passed as zero by all callers. One could retain that argument just
-in case somebody eventually needs to use the extra flexibility that it
-provides. By that time, though, chances are good that the code which
-implements this extra argument has been broken in some subtle way which was
-never noticed - because it has never been used. Or, when the need for
-extra flexibility arises, it does not do so in a way which matches the
-programmer's early expectation. Kernel developers will routinely submit
-patches to remove unused arguments; they should, in general, not be added
-in the first place.
-
-Abstraction layers which hide access to hardware - often to allow the bulk
-of a driver to be used with multiple operating systems - are especially
-frowned upon. Such layers obscure the code and may impose a performance
-penalty; they do not belong in the Linux kernel.
-
-On the other hand, if you find yourself copying significant amounts of code
-from another kernel subsystem, it is time to ask whether it would, in fact,
-make sense to pull out some of that code into a separate library or to
-implement that functionality at a higher level. There is no value in
-replicating the same code throughout the kernel.
-
-
-* #ifdef and preprocessor use in general
-
-The C preprocessor seems to present a powerful temptation to some C
-programmers, who see it as a way to efficiently encode a great deal of
-flexibility into a source file. But the preprocessor is not C, and heavy
-use of it results in code which is much harder for others to read and
-harder for the compiler to check for correctness. Heavy preprocessor use
-is almost always a sign of code which needs some cleanup work.
-
-Conditional compilation with #ifdef is, indeed, a powerful feature, and it
-is used within the kernel. But there is little desire to see code which is
-sprinkled liberally with #ifdef blocks. As a general rule, #ifdef use
-should be confined to header files whenever possible.
-Conditionally-compiled code can be confined to functions which, if the code
-is not to be present, simply become empty. The compiler will then quietly
-optimize out the call to the empty function. The result is far cleaner
-code which is easier to follow.
-
-C preprocessor macros present a number of hazards, including possible
-multiple evaluation of expressions with side effects and no type safety.
-If you are tempted to define a macro, consider creating an inline function
-instead. The code which results will be the same, but inline functions are
-easier to read, do not evaluate their arguments multiple times, and allow
-the compiler to perform type checking on the arguments and return value.
-
-
-* Inline functions
-
-Inline functions present a hazard of their own, though. Programmers can
-become enamored of the perceived efficiency inherent in avoiding a function
-call and fill a source file with inline functions. Those functions,
-however, can actually reduce performance. Since their code is replicated
-at each call site, they end up bloating the size of the compiled kernel.
-That, in turn, creates pressure on the processor's memory caches, which can
-slow execution dramatically. Inline functions, as a rule, should be quite
-small and relatively rare. The cost of a function call, after all, is not
-that high; the creation of large numbers of inline functions is a classic
-example of premature optimization.
-
-In general, kernel programmers ignore cache effects at their peril. The
-classic time/space tradeoff taught in beginning data structures classes
-often does not apply to contemporary hardware. Space *is* time, in that a
-larger program will run slower than one which is more compact.
-
-More recent compilers take an increasingly active role in deciding whether
-a given function should actually be inlined or not. So the liberal
-placement of "inline" keywords may not just be excessive; it could also be
-irrelevant.
-
-
-* Locking
-
-In May, 2006, the "Devicescape" networking stack was, with great
-fanfare, released under the GPL and made available for inclusion in the
-mainline kernel. This donation was welcome news; support for wireless
-networking in Linux was considered substandard at best, and the Devicescape
-stack offered the promise of fixing that situation. Yet, this code did not
-actually make it into the mainline until June, 2007 (2.6.22). What
-happened?
-
-This code showed a number of signs of having been developed behind
-corporate doors. But one large problem in particular was that it was not
-designed to work on multiprocessor systems. Before this networking stack
-(now called mac80211) could be merged, a locking scheme needed to be
-retrofitted onto it.
-
-Once upon a time, Linux kernel code could be developed without thinking
-about the concurrency issues presented by multiprocessor systems. Now,
-however, this document is being written on a dual-core laptop. Even on
-single-processor systems, work being done to improve responsiveness will
-raise the level of concurrency within the kernel. The days when kernel
-code could be written without thinking about locking are long past.
-
-Any resource (data structures, hardware registers, etc.) which could be
-accessed concurrently by more than one thread must be protected by a lock.
-New code should be written with this requirement in mind; retrofitting
-locking after the fact is a rather more difficult task. Kernel developers
-should take the time to understand the available locking primitives well
-enough to pick the right tool for the job. Code which shows a lack of
-attention to concurrency will have a difficult path into the mainline.
-
-
-* Regressions
-
-One final hazard worth mentioning is this: it can be tempting to make a
-change (which may bring big improvements) which causes something to break
-for existing users. This kind of change is called a "regression," and
-regressions have become most unwelcome in the mainline kernel. With few
-exceptions, changes which cause regressions will be backed out if the
-regression cannot be fixed in a timely manner. Far better to avoid the
-regression in the first place.
-
-It is often argued that a regression can be justified if it causes things
-to work for more people than it creates problems for. Why not make a
-change if it brings new functionality to ten systems for each one it
-breaks? The best answer to this question was expressed by Linus in July,
-2007:
-
- So we don't fix bugs by introducing new problems. That way lies
- madness, and nobody ever knows if you actually make any real
- progress at all. Is it two steps forwards, one step back, or one
- step forward and two steps back?
-
-(http://lwn.net/Articles/243460/).
-
-An especially unwelcome type of regression is any sort of change to the
-user-space ABI. Once an interface has been exported to user space, it must
-be supported indefinitely. This fact makes the creation of user-space
-interfaces particularly challenging: since they cannot be changed in
-incompatible ways, they must be done right the first time. For this
-reason, a great deal of thought, clear documentation, and wide review for
-user-space interfaces is always required.
-
-
-
-4.2: CODE CHECKING TOOLS
-
-For now, at least, the writing of error-free code remains an ideal that few
-of us can reach. What we can hope to do, though, is to catch and fix as
-many of those errors as possible before our code goes into the mainline
-kernel. To that end, the kernel developers have put together an impressive
-array of tools which can catch a wide variety of obscure problems in an
-automated way. Any problem caught by the computer is a problem which will
-not afflict a user later on, so it stands to reason that the automated
-tools should be used whenever possible.
-
-The first step is simply to heed the warnings produced by the compiler.
-Contemporary versions of gcc can detect (and warn about) a large number of
-potential errors. Quite often, these warnings point to real problems.
-Code submitted for review should, as a rule, not produce any compiler
-warnings. When silencing warnings, take care to understand the real cause
-and try to avoid "fixes" which make the warning go away without addressing
-its cause.
-
-Note that not all compiler warnings are enabled by default. Build the
-kernel with "make EXTRA_CFLAGS=-W" to get the full set.
-
-The kernel provides several configuration options which turn on debugging
-features; most of these are found in the "kernel hacking" submenu. Several
-of these options should be turned on for any kernel used for development or
-testing purposes. In particular, you should turn on:
-
- - ENABLE_WARN_DEPRECATED, ENABLE_MUST_CHECK, and FRAME_WARN to get an
- extra set of warnings for problems like the use of deprecated interfaces
- or ignoring an important return value from a function. The output
- generated by these warnings can be verbose, but one need not worry about
- warnings from other parts of the kernel.
-
- - DEBUG_OBJECTS will add code to track the lifetime of various objects
- created by the kernel and warn when things are done out of order. If
- you are adding a subsystem which creates (and exports) complex objects
- of its own, consider adding support for the object debugging
- infrastructure.
-
- - DEBUG_SLAB can find a variety of memory allocation and use errors; it
- should be used on most development kernels.
-
- - DEBUG_SPINLOCK, DEBUG_ATOMIC_SLEEP, and DEBUG_MUTEXES will find a
- number of common locking errors.
-
-There are quite a few other debugging options, some of which will be
-discussed below. Some of them have a significant performance impact and
-should not be used all of the time. But some time spent learning the
-available options will likely be paid back many times over in short order.
-
-One of the heavier debugging tools is the locking checker, or "lockdep."
-This tool will track the acquisition and release of every lock (spinlock or
-mutex) in the system, the order in which locks are acquired relative to
-each other, the current interrupt environment, and more. It can then
-ensure that locks are always acquired in the same order, that the same
-interrupt assumptions apply in all situations, and so on. In other words,
-lockdep can find a number of scenarios in which the system could, on rare
-occasion, deadlock. This kind of problem can be painful (for both
-developers and users) in a deployed system; lockdep allows them to be found
-in an automated manner ahead of time. Code with any sort of non-trivial
-locking should be run with lockdep enabled before being submitted for
-inclusion.
-
-As a diligent kernel programmer, you will, beyond doubt, check the return
-status of any operation (such as a memory allocation) which can fail. The
-fact of the matter, though, is that the resulting failure recovery paths
-are, probably, completely untested. Untested code tends to be broken code;
-you could be much more confident of your code if all those error-handling
-paths had been exercised a few times.
-
-The kernel provides a fault injection framework which can do exactly that,
-especially where memory allocations are involved. With fault injection
-enabled, a configurable percentage of memory allocations will be made to
-fail; these failures can be restricted to a specific range of code.
-Running with fault injection enabled allows the programmer to see how the
-code responds when things go badly. See
-Documentation/fault-injection/fault-injection.txt for more information on
-how to use this facility.
-
-Other kinds of errors can be found with the "sparse" static analysis tool.
-With sparse, the programmer can be warned about confusion between
-user-space and kernel-space addresses, mixture of big-endian and
-small-endian quantities, the passing of integer values where a set of bit
-flags is expected, and so on. Sparse must be installed separately (it can
-be found at https://sparse.wiki.kernel.org/index.php/Main_Page if your
-distributor does not package it); it can then be run on the code by adding
-"C=1" to your make command.
-
-The "Coccinelle" tool (http://coccinelle.lip6.fr/) is able to find a wide
-variety of potential coding problems; it can also propose fixes for those
-problems. Quite a few "semantic patches" for the kernel have been packaged
-under the scripts/coccinelle directory; running "make coccicheck" will run
-through those semantic patches and report on any problems found. See
-Documentation/coccinelle.txt for more information.
-
-Other kinds of portability errors are best found by compiling your code for
-other architectures. If you do not happen to have an S/390 system or a
-Blackfin development board handy, you can still perform the compilation
-step. A large set of cross compilers for x86 systems can be found at
-
- http://www.kernel.org/pub/tools/crosstool/
-
-Some time spent installing and using these compilers will help avoid
-embarrassment later.
-
-
-4.3: DOCUMENTATION
-
-Documentation has often been more the exception than the rule with kernel
-development. Even so, adequate documentation will help to ease the merging
-of new code into the kernel, make life easier for other developers, and
-will be helpful for your users. In many cases, the addition of
-documentation has become essentially mandatory.
-
-The first piece of documentation for any patch is its associated
-changelog. Log entries should describe the problem being solved, the form
-of the solution, the people who worked on the patch, any relevant
-effects on performance, and anything else that might be needed to
-understand the patch. Be sure that the changelog says *why* the patch is
-worth applying; a surprising number of developers fail to provide that
-information.
-
-Any code which adds a new user-space interface - including new sysfs or
-/proc files - should include documentation of that interface which enables
-user-space developers to know what they are working with. See
-Documentation/ABI/README for a description of how this documentation should
-be formatted and what information needs to be provided.
-
-The file Documentation/kernel-parameters.txt describes all of the kernel's
-boot-time parameters. Any patch which adds new parameters should add the
-appropriate entries to this file.
-
-Any new configuration options must be accompanied by help text which
-clearly explains the options and when the user might want to select them.
-
-Internal API information for many subsystems is documented by way of
-specially-formatted comments; these comments can be extracted and formatted
-in a number of ways by the "kernel-doc" script. If you are working within
-a subsystem which has kerneldoc comments, you should maintain them and add
-them, as appropriate, for externally-available functions. Even in areas
-which have not been so documented, there is no harm in adding kerneldoc
-comments for the future; indeed, this can be a useful activity for
-beginning kernel developers. The format of these comments, along with some
-information on how to create kerneldoc templates can be found in the file
-Documentation/kernel-documentation.rst.
-
-Anybody who reads through a significant amount of existing kernel code will
-note that, often, comments are most notable by their absence. Once again,
-the expectations for new code are higher than they were in the past;
-merging uncommented code will be harder. That said, there is little desire
-for verbosely-commented code. The code should, itself, be readable, with
-comments explaining the more subtle aspects.
-
-Certain things should always be commented. Uses of memory barriers should
-be accompanied by a line explaining why the barrier is necessary. The
-locking rules for data structures generally need to be explained somewhere.
-Major data structures need comprehensive documentation in general.
-Non-obvious dependencies between separate bits of code should be pointed
-out. Anything which might tempt a code janitor to make an incorrect
-"cleanup" needs a comment saying why it is done the way it is. And so on.
-
-
-4.4: INTERNAL API CHANGES
-
-The binary interface provided by the kernel to user space cannot be broken
-except under the most severe circumstances. The kernel's internal
-programming interfaces, instead, are highly fluid and can be changed when
-the need arises. If you find yourself having to work around a kernel API,
-or simply not using a specific functionality because it does not meet your
-needs, that may be a sign that the API needs to change. As a kernel
-developer, you are empowered to make such changes.
-
-There are, of course, some catches. API changes can be made, but they need
-to be well justified. So any patch making an internal API change should be
-accompanied by a description of what the change is and why it is
-necessary. This kind of change should also be broken out into a separate
-patch, rather than buried within a larger patch.
-
-The other catch is that a developer who changes an internal API is
-generally charged with the task of fixing any code within the kernel tree
-which is broken by the change. For a widely-used function, this duty can
-lead to literally hundreds or thousands of changes - many of which are
-likely to conflict with work being done by other developers. Needless to
-say, this can be a large job, so it is best to be sure that the
-justification is solid. Note that the Coccinelle tool can help with
-wide-ranging API changes.
-
-When making an incompatible API change, one should, whenever possible,
-ensure that code which has not been updated is caught by the compiler.
-This will help you to be sure that you have found all in-tree uses of that
-interface. It will also alert developers of out-of-tree code that there is
-a change that they need to respond to. Supporting out-of-tree code is not
-something that kernel developers need to be worried about, but we also do
-not have to make life harder for out-of-tree developers than it needs to
-be.

+
+Getting the code right
+======================
+
+While there is much to be said for a solid and community-oriented design
+process, the proof of any kernel development project is in the resulting
+code. It is the code which will be examined by other developers and merged
+(or not) into the mainline tree. So it is the quality of this code which
+will determine the ultimate success of the project.
+
+This section will examine the coding process. We'll start with a look at a
+number of ways in which kernel developers can go wrong. Then the focus
+will shift toward doing things right and the tools which can help in that
+quest.
+
+
+Pitfalls
+---------
+
+Coding style
+************
+
+The kernel has long had a standard coding style, described in
+Documentation/CodingStyle. For much of that time, the policies described
+in that file were taken as being, at most, advisory. As a result, there is
+a substantial amount of code in the kernel which does not meet the coding
+style guidelines. The presence of that code leads to two independent
+hazards for kernel developers.
+
+The first of these is to believe that the kernel coding standards do not
+matter and are not enforced. The truth of the matter is that adding new
+code to the kernel is very difficult if that code is not coded according to
+the standard; many developers will request that the code be reformatted
+before they will even review it. A code base as large as the kernel
+requires some uniformity of code to make it possible for developers to
+quickly understand any part of it. So there is no longer room for
+strangely-formatted code.
+
+Occasionally, the kernel's coding style will run into conflict with an
+employer's mandated style. In such cases, the kernel's style will have to
+win before the code can be merged. Putting code into the kernel means
+giving up a degree of control in a number of ways - including control over
+how the code is formatted.
+
+The other trap is to assume that code which is already in the kernel is
+urgently in need of coding style fixes. Developers may start to generate
+reformatting patches as a way of gaining familiarity with the process, or
+as a way of getting their name into the kernel changelogs - or both. But
+pure coding style fixes are seen as noise by the development community;
+they tend to get a chilly reception. So this type of patch is best
+avoided. It is natural to fix the style of a piece of code while working
+on it for other reasons, but coding style changes should not be made for
+their own sake.
+
+The coding style document also should not be read as an absolute law which
+can never be transgressed. If there is a good reason to go against the
+style (a line which becomes far less readable if split to fit within the
+80-column limit, for example), just do it.
+
+
+Abstraction layers
+******************
+
+Computer Science professors teach students to make extensive use of
+abstraction layers in the name of flexibility and information hiding.
+Certainly the kernel makes extensive use of abstraction; no project
+involving several million lines of code could do otherwise and survive.
+But experience has shown that excessive or premature abstraction can be
+just as harmful as premature optimization. Abstraction should be used to
+the level required and no further.
+
+At a simple level, consider a function which has an argument which is
+always passed as zero by all callers. One could retain that argument just
+in case somebody eventually needs to use the extra flexibility that it
+provides. By that time, though, chances are good that the code which
+implements this extra argument has been broken in some subtle way which was
+never noticed - because it has never been used. Or, when the need for
+extra flexibility arises, it does not do so in a way which matches the
+programmer's early expectation. Kernel developers will routinely submit
+patches to remove unused arguments; they should, in general, not be added
+in the first place.
+
+Abstraction layers which hide access to hardware - often to allow the bulk
+of a driver to be used with multiple operating systems - are especially
+frowned upon. Such layers obscure the code and may impose a performance
+penalty; they do not belong in the Linux kernel.
+
+On the other hand, if you find yourself copying significant amounts of code
+from another kernel subsystem, it is time to ask whether it would, in fact,
+make sense to pull out some of that code into a separate library or to
+implement that functionality at a higher level. There is no value in
+replicating the same code throughout the kernel.
+
+
+#ifdef and preprocessor use in general
+**************************************
+
+The C preprocessor seems to present a powerful temptation to some C
+programmers, who see it as a way to efficiently encode a great deal of
+flexibility into a source file. But the preprocessor is not C, and heavy
+use of it results in code which is much harder for others to read and
+harder for the compiler to check for correctness. Heavy preprocessor use
+is almost always a sign of code which needs some cleanup work.
+
+Conditional compilation with #ifdef is, indeed, a powerful feature, and it
+is used within the kernel. But there is little desire to see code which is
+sprinkled liberally with #ifdef blocks. As a general rule, #ifdef use
+should be confined to header files whenever possible.
+Conditionally-compiled code can be confined to functions which, if the code
+is not to be present, simply become empty. The compiler will then quietly
+optimize out the call to the empty function. The result is far cleaner
+code which is easier to follow.
+
+C preprocessor macros present a number of hazards, including possible
+multiple evaluation of expressions with side effects and no type safety.
+If you are tempted to define a macro, consider creating an inline function
+instead. The code which results will be the same, but inline functions are
+easier to read, do not evaluate their arguments multiple times, and allow
+the compiler to perform type checking on the arguments and return value.
+
+
+Inline functions
+****************
+
+Inline functions present a hazard of their own, though. Programmers can
+become enamored of the perceived efficiency inherent in avoiding a function
+call and fill a source file with inline functions. Those functions,
+however, can actually reduce performance. Since their code is replicated
+at each call site, they end up bloating the size of the compiled kernel.
+That, in turn, creates pressure on the processor's memory caches, which can
+slow execution dramatically. Inline functions, as a rule, should be quite
+small and relatively rare. The cost of a function call, after all, is not
+that high; the creation of large numbers of inline functions is a classic
+example of premature optimization.
+
+In general, kernel programmers ignore cache effects at their peril. The
+classic time/space tradeoff taught in beginning data structures classes
+often does not apply to contemporary hardware. Space *is* time, in that a
+larger program will run slower than one which is more compact.
+
+More recent compilers take an increasingly active role in deciding whether
+a given function should actually be inlined or not. So the liberal
+placement of "inline" keywords may not just be excessive; it could also be
+irrelevant.
+

+The "Coccinelle" tool (http://coccinelle.lip6.fr/) is able to find a wide
+variety of potential coding problems; it can also propose fixes for those
+problems. Quite a few "semantic patches" for the kernel have been packaged
+under the scripts/coccinelle directory; running "make coccicheck" will run
+through those semantic patches and report on any problems found. See
+Documentation/coccinelle.txt for more information.
+
+Other kinds of portability errors are best found by compiling your code for
+other architectures. If you do not happen to have an S/390 system or a
+Blackfin development board handy, you can still perform the compilation
+step. A large set of cross compilers for x86 systems can be found at
+
+ http://www.kernel.org/pub/tools/crosstool/
+
+Some time spent installing and using these compilers will help avoid
+embarrassment later.
+
+
+Documentation
+-------------
+
+Documentation has often been more the exception than the rule with kernel
+development. Even so, adequate documentation will help to ease the merging
+of new code into the kernel, make life easier for other developers, and
+will be helpful for your users. In many cases, the addition of
+documentation has become essentially mandatory.
+
+The first piece of documentation for any patch is its associated
+changelog. Log entries should describe the problem being solved, the form
+of the solution, the people who worked on the patch, any relevant
+effects on performance, and anything else that might be needed to
+understand the patch. Be sure that the changelog says *why* the patch is
+worth applying; a surprising number of developers fail to provide that
+information.
+
+Any code which adds a new user-space interface - including new sysfs or
+/proc files - should include documentation of that interface which enables
+user-space developers to know what they are working with. See
+Documentation/ABI/README for a description of how this documentation should
+be formatted and what information needs to be provided.
+
+The file Documentation/kernel-parameters.txt describes all of the kernel's
+boot-time parameters. Any patch which adds new parameters should add the
+appropriate entries to this file.
+
+Any new configuration options must be accompanied by help text which
+clearly explains the options and when the user might want to select them.
+
+Internal API information for many subsystems is documented by way of
+specially-formatted comments; these comments can be extracted and formatted
+in a number of ways by the "kernel-doc" script. If you are working within
+a subsystem which has kerneldoc comments, you should maintain them and add
+them, as appropriate, for externally-available functions. Even in areas
+which have not been so documented, there is no harm in adding kerneldoc
+comments for the future; indeed, this can be a useful activity for
+beginning kernel developers. The format of these comments, along with some
+information on how to create kerneldoc templates can be found in the file
+Documentation/kernel-documentation.rst.
+
+Anybody who reads through a significant amount of existing kernel code will
+note that, often, comments are most notable by their absence. Once again,
+the expectations for new code are higher than they were in the past;
+merging uncommented code will be harder. That said, there is little desire
+for verbosely-commented code. The code should, itself, be readable, with
+comments explaining the more subtle aspects.
+
+Certain things should always be commented. Uses of memory barriers should
+be accompanied by a line explaining why the barrier is necessary. The
+locking rules for data structures generally need to be explained somewhere.
+Major data structures need comprehensive documentation in general.
+Non-obvious dependencies between separate bits of code should be pointed
+out. Anything which might tempt a code janitor to make an incorrect
+"cleanup" needs a comment saying why it is done the way it is. And so on.
+
+
+Internal API changes
+--------------------
+
+The binary interface provided by the kernel to user space cannot be broken
+except under the most severe circumstances. The kernel's internal
+programming interfaces, instead, are highly fluid and can be changed when
+the need arises. If you find yourself having to work around a kernel API,
+or simply not using a specific functionality because it does not meet your
+needs, that may be a sign that the API needs to change. As a kernel
+developer, you are empowered to make such changes.
+
+There are, of course, some catches. API changes can be made, but they need
+to be well justified. So any patch making an internal API change should be
+accompanied by a description of what the change is and why it is
+necessary. This kind of change should also be broken out into a separate
+patch, rather than buried within a larger patch.
+
+The other catch is that a developer who changes an internal API is
+generally charged with the task of fixing any code within the kernel tree
+which is broken by the change. For a widely-used function, this duty can
+lead to literally hundreds or thousands of changes - many of which are
+likely to conflict with work being done by other developers. Needless to
+say, this can be a large job, so it is best to be sure that the
+justification is solid. Note that the Coccinelle tool can help with
+wide-ranging API changes.
+
+When making an incompatible API change, one should, whenever possible,
+ensure that code which has not been updated is caught by the compiler.
+This will help you to be sure that you have found all in-tree uses of that
+interface. It will also alert developers of out-of-tree code that there is
+a change that they need to respond to. Supporting out-of-tree code is not
+something that kernel developers need to be worried about, but we also do
+not have to make life harder for out-of-tree developers than it needs to
+be.

-5: POSTING PATCHES
-
-Sooner or later, the time comes when your work is ready to be presented to
-the community for review and, eventually, inclusion into the mainline
-kernel. Unsurprisingly, the kernel development community has evolved a set
-of conventions and procedures which are used in the posting of patches;
-following them will make life much easier for everybody involved. This
-document will attempt to cover these expectations in reasonable detail;
-more information can also be found in the files SubmittingPatches,
-SubmittingDrivers, and SubmitChecklist in the kernel documentation
-directory.
-
-
-5.1: WHEN TO POST
-
-There is a constant temptation to avoid posting patches before they are
-completely "ready." For simple patches, that is not a problem. If the
-work being done is complex, though, there is a lot to be gained by getting
-feedback from the community before the work is complete. So you should
-consider posting in-progress work, or even making a git tree available so
-that interested developers can catch up with your work at any time.
-
-When posting code which is not yet considered ready for inclusion, it is a
-good idea to say so in the posting itself. Also mention any major work
-which remains to be done and any known problems. Fewer people will look at
-patches which are known to be half-baked, but those who do will come in
-with the idea that they can help you drive the work in the right direction.
-
-
-5.2: BEFORE CREATING PATCHES
-
-There are a number of things which should be done before you consider
-sending patches to the development community. These include:
-
- - Test the code to the extent that you can. Make use of the kernel's
- debugging tools, ensure that the kernel will build with all reasonable
- combinations of configuration options, use cross-compilers to build for
- different architectures, etc.
-
- - Make sure your code is compliant with the kernel coding style
- guidelines.
-
- - Does your change have performance implications? If so, you should run
- benchmarks showing what the impact (or benefit) of your change is; a
- summary of the results should be included with the patch.
-
- - Be sure that you have the right to post the code. If this work was done
- for an employer, the employer likely has a right to the work and must be
- agreeable with its release under the GPL.
-
-As a general rule, putting in some extra thought before posting code almost
-always pays back the effort in short order.
-
-
-5.3: PATCH PREPARATION
-
-The preparation of patches for posting can be a surprising amount of work,
-but, once again, attempting to save time here is not generally advisable
-even in the short term.
-
-Patches must be prepared against a specific version of the kernel. As a
-general rule, a patch should be based on the current mainline as found in
-Linus's git tree. When basing on mainline, start with a well-known release
-point - a stable or -rc release - rather than branching off the mainline at
-an arbitrary spot.
-
-It may become necessary to make versions against -mm, linux-next, or a
-subsystem tree, though, to facilitate wider testing and review. Depending
-on the area of your patch and what is going on elsewhere, basing a patch
-against these other trees can require a significant amount of work
-resolving conflicts and dealing with API changes.
-
-Only the most simple changes should be formatted as a single patch;
-everything else should be made as a logical series of changes. Splitting
-up patches is a bit of an art; some developers spend a long time figuring
-out how to do it in the way that the community expects. There are a few
-rules of thumb, however, which can help considerably:
-
- - The patch series you post will almost certainly not be the series of
- changes found in your working revision control system. Instead, the
- changes you have made need to be considered in their final form, then
- split apart in ways which make sense. The developers are interested in
- discrete, self-contained changes, not the path you took to get to those
- changes.
-
- - Each logically independent change should be formatted as a separate
- patch. These changes can be small ("add a field to this structure") or
- large (adding a significant new driver, for example), but they should be
- conceptually small and amenable to a one-line description. Each patch
- should make a specific change which can be reviewed on its own and
- verified to do what it says it does.
-
- - As a way of restating the guideline above: do not mix different types of
- changes in the same patch. If a single patch fixes a critical security
- bug, rearranges a few structures, and reformats the code, there is a
- good chance that it will be passed over and the important fix will be
- lost.
-
- - Each patch should yield a kernel which builds and runs properly; if your
- patch series is interrupted in the middle, the result should still be a
- working kernel. Partial application of a patch series is a common
- scenario when the "git bisect" tool is used to find regressions; if the
- result is a broken kernel, you will make life harder for developers and
- users who are engaging in the noble work of tracking down problems.
-
- - Do not overdo it, though. One developer once posted a set of edits
- to a single file as 500 separate patches - an act which did not make him
- the most popular person on the kernel mailing list. A single patch can
- be reasonably large as long as it still contains a single *logical*
- change.
-
- - It can be tempting to add a whole new infrastructure with a series of
- patches, but to leave that infrastructure unused until the final patch
- in the series enables the whole thing. This temptation should be
- avoided if possible; if that series adds regressions, bisection will
- finger the last patch as the one which caused the problem, even though
- the real bug is elsewhere. Whenever possible, a patch which adds new
- code should make that code active immediately.
-
-Working to create the perfect patch series can be a frustrating process
-which takes quite a bit of time and thought after the "real work" has been
-done. When done properly, though, it is time well spent.
-
-
-5.4: PATCH FORMATTING AND CHANGELOGS
-
-So now you have a perfect series of patches for posting, but the work is
-not done quite yet. Each patch needs to be formatted into a message which
-quickly and clearly communicates its purpose to the rest of the world. To
-that end, each patch will be composed of the following:
-
- - An optional "From" line naming the author of the patch. This line is
- only necessary if you are passing on somebody else's patch via email,
- but it never hurts to add it when in doubt.
-
- - A one-line description of what the patch does. This message should be
- enough for a reader who sees it with no other context to figure out the
- scope of the patch; it is the line that will show up in the "short form"
- changelogs. This message is usually formatted with the relevant
- subsystem name first, followed by the purpose of the patch. For
- example:
-
- gpio: fix build on CONFIG_GPIO_SYSFS=n
-
- - A blank line followed by a detailed description of the contents of the
- patch. This description can be as long as is required; it should say
- what the patch does and why it should be applied to the kernel.
-
- - One or more tag lines, with, at a minimum, one Signed-off-by: line from
- the author of the patch. Tags will be described in more detail below.
-
-The items above, together, form the changelog for the patch. Writing good
-changelogs is a crucial but often-neglected art; it's worth spending
-another moment discussing this issue. When writing a changelog, you should
-bear in mind that a number of different people will be reading your words.
-These include subsystem maintainers and reviewers who need to decide
-whether the patch should be included, distributors and other maintainers
-trying to decide whether a patch should be backported to other kernels, bug
-hunters wondering whether the patch is responsible for a problem they are
-chasing, users who want to know how the kernel has changed, and more. A
-good changelog conveys the needed information to all of these people in the
-most direct and concise way possible.
-
-To that end, the summary line should describe the effects of and motivation
-for the change as well as possible given the one-line constraint. The
-detailed description can then amplify on those topics and provide any
-needed additional information. If the patch fixes a bug, cite the commit
-which introduced the bug if possible (and please provide both the commit ID
-and the title when citing commits). If a problem is associated with
-specific log or compiler output, include that output to help others
-searching for a solution to the same problem. If the change is meant to
-support other changes coming in later patch, say so. If internal APIs are
-changed, detail those changes and how other developers should respond. In
-general, the more you can put yourself into the shoes of everybody who will
-be reading your changelog, the better that changelog (and the kernel as a
-whole) will be.
-
-Needless to say, the changelog should be the text used when committing the
-change to a revision control system. It will be followed by:
-
- - The patch itself, in the unified ("-u") patch format. Using the "-p"
- option to diff will associate function names with changes, making the
- resulting patch easier for others to read.
-
-You should avoid including changes to irrelevant files (those generated by
-the build process, for example, or editor backup files) in the patch. The
-file "dontdiff" in the Documentation directory can help in this regard;
-pass it to diff with the "-X" option.
-
-The tags mentioned above are used to describe how various developers have
-been associated with the development of this patch. They are described in
-detail in the SubmittingPatches document; what follows here is a brief
-summary. Each of these lines has the format:
-
- tag: Full Name <email address> optional-other-stuff
-
-The tags in common use are:
-
- - Signed-off-by: this is a developer's certification that he or she has
- the right to submit the patch for inclusion into the kernel. It is an
- agreement to the Developer's Certificate of Origin, the full text of
- which can be found in Documentation/SubmittingPatches. Code without a
- proper signoff cannot be merged into the mainline.
-
- - Acked-by: indicates an agreement by another developer (often a
- maintainer of the relevant code) that the patch is appropriate for
- inclusion into the kernel.
-
- - Tested-by: states that the named person has tested the patch and found
- it to work.
-
- - Reviewed-by: the named developer has reviewed the patch for correctness;
- see the reviewer's statement in Documentation/SubmittingPatches for more
- detail.
-
- - Reported-by: names a user who reported a problem which is fixed by this
- patch; this tag is used to give credit to the (often underappreciated)
- people who test our code and let us know when things do not work
- correctly.
-
- - Cc: the named person received a copy of the patch and had the
- opportunity to comment on it.
-
-Be careful in the addition of tags to your patches: only Cc: is appropriate
-for addition without the explicit permission of the person named.
-
-
-5.5: SENDING THE PATCH
-
-Before you mail your patches, there are a couple of other things you should
-take care of:
-
- - Are you sure that your mailer will not corrupt the patches? Patches
- which have had gratuitous white-space changes or line wrapping performed
- by the mail client will not apply at the other end, and often will not
- be examined in any detail. If there is any doubt at all, mail the patch
- to yourself and convince yourself that it shows up intact.
-
- Documentation/email-clients.txt has some helpful hints on making
- specific mail clients work for sending patches.
-
- - Are you sure your patch is free of silly mistakes? You should always
- run patches through scripts/checkpatch.pl and address the complaints it
- comes up with. Please bear in mind that checkpatch.pl, while being the
- embodiment of a fair amount of thought about what kernel patches should
- look like, is not smarter than you. If fixing a checkpatch.pl complaint
- would make the code worse, don't do it.
-
-Patches should always be sent as plain text. Please do not send them as
-attachments; that makes it much harder for reviewers to quote sections of
-the patch in their replies. Instead, just put the patch directly into your
-message.
-
-When mailing patches, it is important to send copies to anybody who might
-be interested in it. Unlike some other projects, the kernel encourages
-people to err on the side of sending too many copies; don't assume that the
-relevant people will see your posting on the mailing lists. In particular,
-copies should go to:
-
- - The maintainer(s) of the affected subsystem(s). As described earlier,
- the MAINTAINERS file is the first place to look for these people.
-
- - Other developers who have been working in the same area - especially
- those who might be working there now. Using git to see who else has
- modified the files you are working on can be helpful.
-
- - If you are responding to a bug report or a feature request, copy the
- original poster as well.
-
- - Send a copy to the relevant mailing list, or, if nothing else applies,
- the linux-kernel list.
-
- - If you are fixing a bug, think about whether the fix should go into the
- next stable update. If so, stable@vger.kernel.org should get a copy of
- the patch. Also add a "Cc: stable@vger.kernel.org" to the tags within
- the patch itself; that will cause the stable team to get a notification
- when your fix goes into the mainline.
-
-When selecting recipients for a patch, it is good to have an idea of who
-you think will eventually accept the patch and get it merged. While it
-is possible to send patches directly to Linus Torvalds and have him merge
-them, things are not normally done that way. Linus is busy, and there are
-subsystem maintainers who watch over specific parts of the kernel. Usually
-you will be wanting that maintainer to merge your patches. If there is no
-obvious maintainer, Andrew Morton is often the patch target of last resort.
-
-Patches need good subject lines. The canonical format for a patch line is
-something like:
-
- [PATCH nn/mm] subsys: one-line description of the patch
-
-where "nn" is the ordinal number of the patch, "mm" is the total number of
-patches in the series, and "subsys" is the name of the affected subsystem.
-Clearly, nn/mm can be omitted for a single, standalone patch.
-
-If you have a significant series of patches, it is customary to send an
-introductory description as part zero. This convention is not universally
-followed though; if you use it, remember that information in the
-introduction does not make it into the kernel changelogs. So please ensure
-that the patches, themselves, have complete changelog information.
-
-In general, the second and following parts of a multi-part patch should be
-sent as a reply to the first part so that they all thread together at the
-receiving end. Tools like git and quilt have commands to mail out a set of
-patches with the proper threading. If you have a long series, though, and
-are using git, please stay away from the --chain-reply-to option to avoid
-creating exceptionally deep nesting.

+You should avoid including changes to irrelevant files (those generated by
+the build process, for example, or editor backup files) in the patch. The
+file "dontdiff" in the Documentation directory can help in this regard;
+pass it to diff with the "-X" option.
+
+The tags mentioned above are used to describe how various developers have
+been associated with the development of this patch. They are described in
+detail in the SubmittingPatches document; what follows here is a brief
+summary. Each of these lines has the format:
+
+::
+
+ tag: Full Name <email address> optional-other-stuff
+
+The tags in common use are:
+
+ - Signed-off-by: this is a developer's certification that he or she has
+ the right to submit the patch for inclusion into the kernel. It is an
+ agreement to the Developer's Certificate of Origin, the full text of
+ which can be found in Documentation/SubmittingPatches. Code without a
+ proper signoff cannot be merged into the mainline.
+
+ - Acked-by: indicates an agreement by another developer (often a
+ maintainer of the relevant code) that the patch is appropriate for
+ inclusion into the kernel.
+
+ - Tested-by: states that the named person has tested the patch and found
+ it to work.
+
+ - Reviewed-by: the named developer has reviewed the patch for correctness;
+ see the reviewer's statement in Documentation/SubmittingPatches for more
+ detail.
+
+ - Reported-by: names a user who reported a problem which is fixed by this
+ patch; this tag is used to give credit to the (often underappreciated)
+ people who test our code and let us know when things do not work
+ correctly.
+
+ - Cc: the named person received a copy of the patch and had the
+ opportunity to comment on it.
+
+Be careful in the addition of tags to your patches: only Cc: is appropriate
+for addition without the explicit permission of the person named.
+
+
+Sending the patch
+-----------------
+
+Before you mail your patches, there are a couple of other things you should
+take care of:
+
+ - Are you sure that your mailer will not corrupt the patches? Patches
+ which have had gratuitous white-space changes or line wrapping performed
+ by the mail client will not apply at the other end, and often will not
+ be examined in any detail. If there is any doubt at all, mail the patch
+ to yourself and convince yourself that it shows up intact.
+
+ Documentation/email-clients.txt has some helpful hints on making
+ specific mail clients work for sending patches.
+
+ - Are you sure your patch is free of silly mistakes? You should always
+ run patches through scripts/checkpatch.pl and address the complaints it
+ comes up with. Please bear in mind that checkpatch.pl, while being the
+ embodiment of a fair amount of thought about what kernel patches should
+ look like, is not smarter than you. If fixing a checkpatch.pl complaint
+ would make the code worse, don't do it.
+
+Patches should always be sent as plain text. Please do not send them as
+attachments; that makes it much harder for reviewers to quote sections of
+the patch in their replies. Instead, just put the patch directly into your
+message.
+
+When mailing patches, it is important to send copies to anybody who might
+be interested in it. Unlike some other projects, the kernel encourages
+people to err on the side of sending too many copies; don't assume that the
+relevant people will see your posting on the mailing lists. In particular,
+copies should go to:
+
+ - The maintainer(s) of the affected subsystem(s). As described earlier,
+ the MAINTAINERS file is the first place to look for these people.
+
+ - Other developers who have been working in the same area - especially
+ those who might be working there now. Using git to see who else has
+ modified the files you are working on can be helpful.
+
+ - If you are responding to a bug report or a feature request, copy the
+ original poster as well.
+
+ - Send a copy to the relevant mailing list, or, if nothing else applies,
+ the linux-kernel list.
+
+ - If you are fixing a bug, think about whether the fix should go into the
+ next stable update. If so, stable@vger.kernel.org should get a copy of
+ the patch. Also add a "Cc: stable@vger.kernel.org" to the tags within
+ the patch itself; that will cause the stable team to get a notification
+ when your fix goes into the mainline.
+
+When selecting recipients for a patch, it is good to have an idea of who
+you think will eventually accept the patch and get it merged. While it
+is possible to send patches directly to Linus Torvalds and have him merge
+them, things are not normally done that way. Linus is busy, and there are
+subsystem maintainers who watch over specific parts of the kernel. Usually
+you will be wanting that maintainer to merge your patches. If there is no
+obvious maintainer, Andrew Morton is often the patch target of last resort.
+
+Patches need good subject lines. The canonical format for a patch line is
+something like:
+
+::
+
+ [PATCH nn/mm] subsys: one-line description of the patch
+
+where "nn" is the ordinal number of the patch, "mm" is the total number of
+patches in the series, and "subsys" is the name of the affected subsystem.
+Clearly, nn/mm can be omitted for a single, standalone patch.
+
+If you have a significant series of patches, it is customary to send an
+introductory description as part zero. This convention is not universally
+followed though; if you use it, remember that information in the
+introduction does not make it into the kernel changelogs. So please ensure
+that the patches, themselves, have complete changelog information.
+
+In general, the second and following parts of a multi-part patch should be
+sent as a reply to the first part so that they all thread together at the
+receiving end. Tools like git and quilt have commands to mail out a set of
+patches with the proper threading. If you have a long series, though, and
+are using git, please stay away from the --chain-reply-to option to avoid
+creating exceptionally deep nesting.

-6: FOLLOWTHROUGH
-
-At this point, you have followed the guidelines given so far and, with the
-addition of your own engineering skills, have posted a perfect series of
-patches. One of the biggest mistakes that even experienced kernel
-developers can make is to conclude that their work is now done. In truth,
-posting patches indicates a transition into the next stage of the process,
-with, possibly, quite a bit of work yet to be done.
-
-It is a rare patch which is so good at its first posting that there is no
-room for improvement. The kernel development process recognizes this fact,
-and, as a result, is heavily oriented toward the improvement of posted
-code. You, as the author of that code, will be expected to work with the
-kernel community to ensure that your code is up to the kernel's quality
-standards. A failure to participate in this process is quite likely to
-prevent the inclusion of your patches into the mainline.
-
-
-6.1: WORKING WITH REVIEWERS
-
-A patch of any significance will result in a number of comments from other
-developers as they review the code. Working with reviewers can be, for
-many developers, the most intimidating part of the kernel development
-process. Life can be made much easier, though, if you keep a few things in
-mind:
-
- - If you have explained your patch well, reviewers will understand its
- value and why you went to the trouble of writing it. But that value
- will not keep them from asking a fundamental question: what will it be
- like to maintain a kernel with this code in it five or ten years later?
- Many of the changes you may be asked to make - from coding style tweaks
- to substantial rewrites - come from the understanding that Linux will
- still be around and under development a decade from now.
-
- - Code review is hard work, and it is a relatively thankless occupation;
- people remember who wrote kernel code, but there is little lasting fame
- for those who reviewed it. So reviewers can get grumpy, especially when
- they see the same mistakes being made over and over again. If you get a
- review which seems angry, insulting, or outright offensive, resist the
- impulse to respond in kind. Code review is about the code, not about
- the people, and code reviewers are not attacking you personally.
-
- - Similarly, code reviewers are not trying to promote their employers'
- agendas at the expense of your own. Kernel developers often expect to
- be working on the kernel years from now, but they understand that their
- employer could change. They truly are, almost without exception,
- working toward the creation of the best kernel they can; they are not
- trying to create discomfort for their employers' competitors.
-
-What all of this comes down to is that, when reviewers send you comments,
-you need to pay attention to the technical observations that they are
-making. Do not let their form of expression or your own pride keep that
-from happening. When you get review comments on a patch, take the time to
-understand what the reviewer is trying to say. If possible, fix the things
-that the reviewer is asking you to fix. And respond back to the reviewer:
-thank them, and describe how you will answer their questions.
-
-Note that you do not have to agree with every change suggested by
-reviewers. If you believe that the reviewer has misunderstood your code,
-explain what is really going on. If you have a technical objection to a
-suggested change, describe it and justify your solution to the problem. If
-your explanations make sense, the reviewer will accept them. Should your
-explanation not prove persuasive, though, especially if others start to
-agree with the reviewer, take some time to think things over again. It can
-be easy to become blinded by your own solution to a problem to the point
-that you don't realize that something is fundamentally wrong or, perhaps,
-you're not even solving the right problem.
-
-Andrew Morton has suggested that every review comment which does not result
-in a code change should result in an additional code comment instead; that
-can help future reviewers avoid the questions which came up the first time
-around.
-
-One fatal mistake is to ignore review comments in the hope that they will
-go away. They will not go away. If you repost code without having
-responded to the comments you got the time before, you're likely to find
-that your patches go nowhere.
-
-Speaking of reposting code: please bear in mind that reviewers are not
-going to remember all the details of the code you posted the last time
-around. So it is always a good idea to remind reviewers of previously
-raised issues and how you dealt with them; the patch changelog is a good
-place for this kind of information. Reviewers should not have to search
-through list archives to familiarize themselves with what was said last
-time; if you help them get a running start, they will be in a better mood
-when they revisit your code.
-
-What if you've tried to do everything right and things still aren't going
-anywhere? Most technical disagreements can be resolved through discussion,
-but there are times when somebody simply has to make a decision. If you
-honestly believe that this decision is going against you wrongly, you can
-always try appealing to a higher power. As of this writing, that higher
-power tends to be Andrew Morton. Andrew has a great deal of respect in the
-kernel development community; he can often unjam a situation which seems to
-be hopelessly blocked. Appealing to Andrew should not be done lightly,
-though, and not before all other alternatives have been explored. And bear
-in mind, of course, that he may not agree with you either.
-
-
-6.2: WHAT HAPPENS NEXT
-
-If a patch is considered to be a good thing to add to the kernel, and once
-most of the review issues have been resolved, the next step is usually
-entry into a subsystem maintainer's tree. How that works varies from one
-subsystem to the next; each maintainer has his or her own way of doing
-things. In particular, there may be more than one tree - one, perhaps,
-dedicated to patches planned for the next merge window, and another for
-longer-term work.
-
-For patches applying to areas for which there is no obvious subsystem tree
-(memory management patches, for example), the default tree often ends up
-being -mm. Patches which affect multiple subsystems can also end up going
-through the -mm tree.
-
-Inclusion into a subsystem tree can bring a higher level of visibility to a
-patch. Now other developers working with that tree will get the patch by
-default. Subsystem trees typically feed linux-next as well, making their
-contents visible to the development community as a whole. At this point,
-there's a good chance that you will get more comments from a new set of
-reviewers; these comments need to be answered as in the previous round.
-
-What may also happen at this point, depending on the nature of your patch,
-is that conflicts with work being done by others turn up. In the worst
-case, heavy patch conflicts can result in some work being put on the back
-burner so that the remaining patches can be worked into shape and merged.
-Other times, conflict resolution will involve working with the other
-developers and, possibly, moving some patches between trees to ensure that
-everything applies cleanly. This work can be a pain, but count your
-blessings: before the advent of the linux-next tree, these conflicts often
-only turned up during the merge window and had to be addressed in a hurry.
-Now they can be resolved at leisure, before the merge window opens.
-
-Some day, if all goes well, you'll log on and see that your patch has been
-merged into the mainline kernel. Congratulations! Once the celebration is
-complete (and you have added yourself to the MAINTAINERS file), though, it
-is worth remembering an important little fact: the job still is not done.
-Merging into the mainline brings its own challenges.
-
-To begin with, the visibility of your patch has increased yet again. There
-may be a new round of comments from developers who had not been aware of
-the patch before. It may be tempting to ignore them, since there is no
-longer any question of your code being merged. Resist that temptation,
-though; you still need to be responsive to developers who have questions or
-suggestions.
-
-More importantly, though: inclusion into the mainline puts your code into
-the hands of a much larger group of testers. Even if you have contributed
-a driver for hardware which is not yet available, you will be surprised by
-how many people will build your code into their kernels. And, of course,
-where there are testers, there will be bug reports.
-
-The worst sort of bug reports are regressions. If your patch causes a
-regression, you'll find an uncomfortable number of eyes upon you;
-regressions need to be fixed as soon as possible. If you are unwilling or
-unable to fix the regression (and nobody else does it for you), your patch
-will almost certainly be removed during the stabilization period. Beyond
-negating all of the work you have done to get your patch into the mainline,
-having a patch pulled as the result of a failure to fix a regression could
-well make it harder for you to get work merged in the future.
-
-After any regressions have been dealt with, there may be other, ordinary
-bugs to deal with. The stabilization period is your best opportunity to
-fix these bugs and ensure that your code's debut in a mainline kernel
-release is as solid as possible. So, please, answer bug reports, and fix
-the problems if at all possible. That's what the stabilization period is
-for; you can start creating cool new patches once any problems with the old
-ones have been taken care of.
-
-And don't forget that there are other milestones which may also create bug
-reports: the next mainline stable release, when prominent distributors pick
-up a version of the kernel containing your patch, etc. Continuing to
-respond to these reports is a matter of basic pride in your work. If that
-is insufficient motivation, though, it's also worth considering that the
-development community remembers developers who lose interest in their code
-after it's merged. The next time you post a patch, they will be evaluating
-it with the assumption that you will not be around to maintain it
-afterward.
-
-
-6.3: OTHER THINGS THAT CAN HAPPEN
-
-One day, you may open your mail client and see that somebody has mailed you
-a patch to your code. That is one of the advantages of having your code
-out there in the open, after all. If you agree with the patch, you can
-either forward it on to the subsystem maintainer (be sure to include a
-proper From: line so that the attribution is correct, and add a signoff of
-your own), or send an Acked-by: response back and let the original poster
-send it upward.
-
-If you disagree with the patch, send a polite response explaining why. If
-possible, tell the author what changes need to be made to make the patch
-acceptable to you. There is a certain resistance to merging patches which
-are opposed by the author and maintainer of the code, but it only goes so
-far. If you are seen as needlessly blocking good work, those patches will
-eventually flow around you and get into the mainline anyway. In the Linux
-kernel, nobody has absolute veto power over any code. Except maybe Linus.
-
-On very rare occasion, you may see something completely different: another
-developer posts a different solution to your problem. At that point,
-chances are that one of the two patches will not be merged, and "mine was
-here first" is not considered to be a compelling technical argument. If
-somebody else's patch displaces yours and gets into the mainline, there is
-really only one way to respond: be pleased that your problem got solved and
-get on with your work. Having one's work shoved aside in this manner can
-be hurtful and discouraging, but the community will remember your reaction
-long after they have forgotten whose patch actually got merged.

-7: ADVANCED TOPICS
-
-At this point, hopefully, you have a handle on how the development process
-works. There is still more to learn, however! This section will cover a
-number of topics which can be helpful for developers wanting to become a
-regular part of the Linux kernel development process.
-
-7.1: MANAGING PATCHES WITH GIT
-
-The use of distributed version control for the kernel began in early 2002,
-when Linus first started playing with the proprietary BitKeeper
-application. While BitKeeper was controversial, the approach to software
-version management it embodied most certainly was not. Distributed version
-control enabled an immediate acceleration of the kernel development
-project. In current times, there are several free alternatives to
-BitKeeper. For better or for worse, the kernel project has settled on git
-as its tool of choice.
-
-Managing patches with git can make life much easier for the developer,
-especially as the volume of those patches grows. Git also has its rough
-edges and poses certain hazards; it is a young and powerful tool which is
-still being civilized by its developers. This document will not attempt to
-teach the reader how to use git; that would be sufficient material for a
-long document in its own right. Instead, the focus here will be on how git
-fits into the kernel development process in particular. Developers who
-wish to come up to speed with git will find more information at:
-
- http://git-scm.com/
-
- http://www.kernel.org/pub/software/scm/git/docs/user-manual.html
-
-and on various tutorials found on the web.
-
-The first order of business is to read the above sites and get a solid
-understanding of how git works before trying to use it to make patches
-available to others. A git-using developer should be able to obtain a copy
-of the mainline repository, explore the revision history, commit changes to
-the tree, use branches, etc. An understanding of git's tools for the
-rewriting of history (such as rebase) is also useful. Git comes with its
-own terminology and concepts; a new user of git should know about refs,
-remote branches, the index, fast-forward merges, pushes and pulls, detached
-heads, etc. It can all be a little intimidating at the outset, but the
-concepts are not that hard to grasp with a bit of study.
-
-Using git to generate patches for submission by email can be a good
-exercise while coming up to speed.
-
-When you are ready to start putting up git trees for others to look at, you
-will, of course, need a server that can be pulled from. Setting up such a
-server with git-daemon is relatively straightforward if you have a system
-which is accessible to the Internet. Otherwise, free, public hosting sites
-(Github, for example) are starting to appear on the net. Established
-developers can get an account on kernel.org, but those are not easy to come
-by; see http://kernel.org/faq/ for more information.
-
-The normal git workflow involves the use of a lot of branches. Each line
-of development can be separated into a separate "topic branch" and
-maintained independently. Branches in git are cheap, there is no reason to
-not make free use of them. And, in any case, you should not do your
-development in any branch which you intend to ask others to pull from.
-Publicly-available branches should be created with care; merge in patches
-from development branches when they are in complete form and ready to go -
-not before.
-
-Git provides some powerful tools which can allow you to rewrite your
-development history. An inconvenient patch (one which breaks bisection,
-say, or which has some other sort of obvious bug) can be fixed in place or
-made to disappear from the history entirely. A patch series can be
-rewritten as if it had been written on top of today's mainline, even though
-you have been working on it for months. Changes can be transparently
-shifted from one branch to another. And so on. Judicious use of git's
-ability to revise history can help in the creation of clean patch sets with
-fewer problems.
-
-Excessive use of this capability can lead to other problems, though, beyond
-a simple obsession for the creation of the perfect project history.
-Rewriting history will rewrite the changes contained in that history,
-turning a tested (hopefully) kernel tree into an untested one. But, beyond
-that, developers cannot easily collaborate if they do not have a shared
-view of the project history; if you rewrite history which other developers
-have pulled into their repositories, you will make life much more difficult
-for those developers. So a simple rule of thumb applies here: history
-which has been exported to others should generally be seen as immutable
-thereafter.
-
-So, once you push a set of changes to your publicly-available server, those
-changes should not be rewritten. Git will attempt to enforce this rule if
-you try to push changes which do not result in a fast-forward merge
-(i.e. changes which do not share the same history). It is possible to
-override this check, and there may be times when it is necessary to rewrite
-an exported tree. Moving changesets between trees to avoid conflicts in
-linux-next is one example. But such actions should be rare. This is one
-of the reasons why development should be done in private branches (which
-can be rewritten if necessary) and only moved into public branches when
-it's in a reasonably advanced state.
-
-As the mainline (or other tree upon which a set of changes is based)
-advances, it is tempting to merge with that tree to stay on the leading
-edge. For a private branch, rebasing can be an easy way to keep up with
-another tree, but rebasing is not an option once a tree is exported to the
-world. Once that happens, a full merge must be done. Merging occasionally
-makes good sense, but overly frequent merges can clutter the history
-needlessly. Suggested technique in this case is to merge infrequently, and
-generally only at specific release points (such as a mainline -rc
-release). If you are nervous about specific changes, you can always
-perform test merges in a private branch. The git "rerere" tool can be
-useful in such situations; it remembers how merge conflicts were resolved
-so that you don't have to do the same work twice.
-
-One of the biggest recurring complaints about tools like git is this: the
-mass movement of patches from one repository to another makes it easy to
-slip in ill-advised changes which go into the mainline below the review
-radar. Kernel developers tend to get unhappy when they see that kind of
-thing happening; putting up a git tree with unreviewed or off-topic patches
-can affect your ability to get trees pulled in the future. Quoting Linus:
-
- You can send me patches, but for me to pull a git patch from you, I
- need to know that you know what you're doing, and I need to be able
- to trust things *without* then having to go and check every
- individual change by hand.
-
-(http://lwn.net/Articles/224135/).
-
-To avoid this kind of situation, ensure that all patches within a given
-branch stick closely to the associated topic; a "driver fixes" branch
-should not be making changes to the core memory management code. And, most
-importantly, do not use a git tree to bypass the review process. Post an
-occasional summary of the tree to the relevant list, and, when the time is
-right, request that the tree be included in linux-next.
-
-If and when others start to send patches for inclusion into your tree,
-don't forget to review them. Also ensure that you maintain the correct
-authorship information; the git "am" tool does its best in this regard, but
-you may have to add a "From:" line to the patch if it has been relayed to
-you via a third party.
-
-When requesting a pull, be sure to give all the relevant information: where
-your tree is, what branch to pull, and what changes will result from the
-pull. The git request-pull command can be helpful in this regard; it will
-format the request as other developers expect, and will also check to be
-sure that you have remembered to push those changes to the public server.
-
-
-7.2: REVIEWING PATCHES
-
-Some readers will certainly object to putting this section with "advanced
-topics" on the grounds that even beginning kernel developers should be
-reviewing patches. It is certainly true that there is no better way to
-learn how to program in the kernel environment than by looking at code
-posted by others. In addition, reviewers are forever in short supply; by
-looking at code you can make a significant contribution to the process as a
-whole.
-
-Reviewing code can be an intimidating prospect, especially for a new kernel
-developer who may well feel nervous about questioning code - in public -
-which has been posted by those with more experience. Even code written by
-the most experienced developers can be improved, though. Perhaps the best
-piece of advice for reviewers (all reviewers) is this: phrase review
-comments as questions rather than criticisms. Asking "how does the lock
-get released in this path?" will always work better than stating "the
-locking here is wrong."
-
-Different developers will review code from different points of view. Some
-are mostly concerned with coding style and whether code lines have trailing
-white space. Others will focus primarily on whether the change implemented
-by the patch as a whole is a good thing for the kernel or not. Yet others
-will check for problematic locking, excessive stack usage, possible
-security issues, duplication of code found elsewhere, adequate
-documentation, adverse effects on performance, user-space ABI changes, etc.
-All types of review, if they lead to better code going into the kernel, are
-welcome and worthwhile.

+
+Advanced topics
+===============
+
+At this point, hopefully, you have a handle on how the development process
+works. There is still more to learn, however! This section will cover a
+number of topics which can be helpful for developers wanting to become a
+regular part of the Linux kernel development process.
+
+Managing patches with git
+-------------------------
+
+The use of distributed version control for the kernel began in early 2002,
+when Linus first started playing with the proprietary BitKeeper
+application. While BitKeeper was controversial, the approach to software
+version management it embodied most certainly was not. Distributed version
+control enabled an immediate acceleration of the kernel development
+project. In current times, there are several free alternatives to
+BitKeeper. For better or for worse, the kernel project has settled on git
+as its tool of choice.
+
+Managing patches with git can make life much easier for the developer,
+especially as the volume of those patches grows. Git also has its rough
+edges and poses certain hazards; it is a young and powerful tool which is
+still being civilized by its developers. This document will not attempt to
+teach the reader how to use git; that would be sufficient material for a
+long document in its own right. Instead, the focus here will be on how git

+Bindings for the Broadcom's brcm,bcm6345-gpio memory-mapped GPIO controllers.
+
+These bindings can be used on any BCM63xx SoC. However, BCM6338 and BCM6345
+are the only ones which don't need a pinctrl driver.
+BCM6338 have 8-bit data and dirout registers, where GPIO state can be read
+and/or written, and the direction changed from input to output.
+BCM6345 have 16-bit data and dirout registers, where GPIO state can be read
+and/or written, and the direction changed from input to output.
+
+Required properties:
+ - compatible: should be "brcm,bcm6345-gpio"
+ - reg-names: must contain
+ "dat" - data register
+ "dirout" - direction (output) register
+ - reg: address + size pairs describing the GPIO register sets;
+ order must correspond with the order of entries in reg-names
+ - #gpio-cells: must be set to 2. The first cell is the pin number and
+ the second cell is used to specify the gpio polarity:
+ 0 = active high
+ 1 = active low
+ - gpio-controller: Marks the device node as a gpio controller.
+
+Optional properties:
+ - native-endian: use native endian memory.
+
+Examples:
+ - BCM6338:

+===============
+
+The Auxiliary Analog/Digital Converter (AUXADC) is an ADC found
+in some Mediatek SoCs which among other things measures the temperatures
+in the SoC. It can be used directly with register accesses, but it is also
+used by thermal controller which reads the temperatures from the AUXADC
+directly via its own bus interface. See
+Documentation/devicetree/bindings/thermal/mediatek-thermal.txt
+for the Thermal Controller which holds a phandle to the AUXADC.
+
+Required properties:
+ - compatible: Should be one of:
+ - "mediatek,mt2701-auxadc": For MT2701 family of SoCs
+ - "mediatek,mt8173-auxadc": For MT8173 family of SoCs
+ - reg: Address range of the AUXADC unit.
+ - clocks: Should contain a clock specifier for each entry in clock-names
+ - clock-names: Should contain "main".
+ - #io-channel-cells: Should be 1, see ../iio-bindings.txt

+Qualcomm PM8058 LED driver
+
+The Qualcomm PM8058 is a multi-functional device which contains
+an LED driver block for up to six LEDs: three normal LEDs, two
+"flash" LEDs and one "keypad backlight" LED. The names are
+quoted because sometimes these LED drivers are used for wildly
+different things than flash or keypad backlight: their names
+are more of a suggestion than a hard-wired usecase.
+
+Hardware-wise the different LEDs support slightly different
+output currents. The "flash" LEDs do not need to charge nor
+do they support external triggers. They are just powerful LED
+drivers.
+
+The LEDs appear as children to the PM8058 device, with the
+proper compatible string. For the PM8058 bindings see:
+mfd/qcom-pm8xxx.txt.
+
+Each LED is represented as a sub-node of the syscon device. Each
+node's name represents the name of the corresponding LED.

* Synopsys DWC Ethernet QoS IP version 4.10 driver (GMAC)
+This binding supports the Synopsys Designware Ethernet QoS (Quality Of Service)
+IP block. The IP supports multiple options for bus type, clocking and reset
+structure, and feature list. Consequently, a number of properties and list
+entries in properties are marked as optional, or only required in specific HW
+configurations.
Required properties:
-- compatible: Should be "snps,dwc-qos-ethernet-4.10"
+- compatible: One of:
+ - "axis,artpec6-eqos", "snps,dwc-qos-ethernet-4.10"
+ Represents the IP core when integrated into the Axis ARTPEC-6 SoC.
+ - "nvidia,tegra186-eqos", "snps,dwc-qos-ethernet-4.10"
+ Represents the IP core when integrated into the NVIDIA Tegra186 SoC.
+ - "snps,dwc-qos-ethernet-4.10"
+ This combination is deprecated. It should be treated as equivalent to
+ "axis,artpec6-eqos", "snps,dwc-qos-ethernet-4.10". It is supported to be
+ compatible with earlier revisions of this binding.
- reg: Address and length of the register set for the device
-- clocks: Phandles to the reference clock and the bus clock
-- clock-names: Should be "phy_ref_clk" for the reference clock and "apb_pclk"
- for the bus clock.
+- clocks: Phandle and clock specifiers for each entry in clock-names, in the
+ same order. See ../clock/clock-bindings.txt.
+- clock-names: May contain any/all of the following depending on the IP
+ configuration, in any order:
+ - "tx"
+ The EQOS transmit path clock. The HW signal name is clk_tx_i.
+ In some configurations (e.g. GMII/RGMII), this clock also drives the PHY TX
+ path. In other configurations, other clocks (such as tx_125, rmii) may
+ drive the PHY TX path.
+ - "rx"
+ The EQOS receive path clock. The HW signal name is clk_rx_i.
+ In some configurations (e.g. GMII/RGMII), this clock is derived from the
+ PHY's RX clock output. In other configurations, other clocks (such as
+ rx_125, rmii) may drive the EQOS RX path.
+ In cases where the PHY clock is directly fed into the EQOS receive path
+ without intervening logic, the DT need not represent this clock, since it
+ is assumed to be fully under the control of the PHY device/driver. In
+ cases where SoC integration adds additional logic to this path, such as a
+ SW-controlled clock gate, this clock should be represented in DT.
+ - "slave_bus"
+ The CPU/slave-bus (CSR) interface clock. This applies to any bus type;
+ APB, AHB, AXI, etc. The HW signal name is hclk_i (AHB) or clk_csr_i (other
+ buses).
+ - "master_bus"
+ The master bus interface clock. Only required in configurations that use a
+ separate clock for the master and slave bus interfaces. The HW signal name
+ is hclk_i (AHB) or aclk_i (AXI).
+ - "ptp_ref"
+ The PTP reference clock. The HW signal name is clk_ptp_ref_i.
+ - "phy_ref_clk"
+ This clock is deprecated and should not be used by new compatible values.
+ It is equivalent to "tx".
+ - "apb_pclk"
+ This clock is deprecated and should not be used by new compatible values.
+ It is equivalent to "slave_bus".
+
+ Note: Support for additional IP configurations may require adding the
+ following clocks to this list in the future: clk_rx_125_i, clk_tx_125_i,
+ clk_pmarx_0_i, clk_pmarx1_i, clk_rmii_i, clk_revmii_rx_i, clk_revmii_tx_i.
+ Configurations exist where multiple similar clocks are used at once, e.g. all
+ of clk_rx_125_i, clk_pmarx_0_i, clk_pmarx1_i. For this reason it is best to
+ extend the binding with a separate clock-names entry for each of those RX
+ clocks, rather than repurposing the existing "rx" clock-names entry as a
+ generic/logical clock in a similar fashion to "master_bus" and "slave_bus".
+ This will allow easy support for configurations that support multiple PHY
+ interfaces using a mux, and hence need to have explicit control over
+ specific RX clocks.
+
+ The following compatible values require the following set of clocks:
+ - "nvidia,tegra186-eqos", "snps,dwc-qos-ethernet-4.10":
+ - "slave_bus"
+ - "master_bus"
+ - "rx"
+ - "tx"
+ - "ptp_ref"
+ - "axis,artpec6-eqos", "snps,dwc-qos-ethernet-4.10":
+ - "slave_bus"
+ - "master_bus"
+ - "tx"
+ - "ptp_ref"
+ - "snps,dwc-qos-ethernet-4.10" (deprecated):
+ - "phy_ref_clk"
+ - "apb_clk"
- interrupt-parent: Should be the phandle for the interrupt controller
that services interrupts for this device
- interrupts: Should contain the core's combined interrupt signal
- phy-mode: See ethernet.txt file in the same directory
+- resets: Phandle and reset specifiers for each entry in reset-names, in the
+ same order. See ../reset/reset.txt.
+- reset-names: May contain any/all of the following depending on the IP
+ configuration, in any order:
+ - "eqos". The reset to the entire module. The HW signal name is hreset_n
+ (AHB) or aresetn_i (AXI).
+
+ The following compatible values require the following set of resets:
+ (the reset properties may be omitted if empty)
+ - "nvidia,tegra186-eqos", "snps,dwc-qos-ethernet-4.10":
+ - "eqos".
+ - "axis,artpec6-eqos", "snps,dwc-qos-ethernet-4.10":
+ - None.
+ - "snps,dwc-qos-ethernet-4.10" (deprecated):
+ - None.
Optional properties:
- dma-coherent: Present if dma operations are coherent
- mac-address: See ethernet.txt in the same directory
- local-mac-address: See ethernet.txt in the same directory
+- phy-reset-gpios: Phandle and specifier for any GPIO used to reset the PHY.
+ See ../gpio/gpio.txt.
- snps,en-lpi: If present it enables use of the AXI low-power interface
- snps,write-requests: Number of write requests that the AXI port can issue.
It depends on the SoC configuration.

+Linear Technology LTC3676 8-output regulators
+
+Required properties:
+- compatible: "lltc,ltc3676"
+- reg: I2C slave address
+
+Required child node:
+- regulators: Contains eight regulator child nodes sw1, sw2, sw3, sw4,
+ ldo1, ldo2, ldo3, and ldo4, specifying the initialization data as
+ documented in Documentation/devicetree/bindings/regulator/regulator.txt.
+
+Each regulator is defined using the standard binding for regulators. The
+nodes for sw1, sw2, sw3, sw4, ldo1, ldo2 and ldo4 additionally need to specify
+the resistor values of their external feedback voltage dividers:
+
+Required properties (not on ldo3):
+- lltc,fb-voltage-divider: An array of two integers containing the resistor
+ values R1 and R2 of the feedback voltage divider in ohms.
+
+Regulators sw1, sw2, sw3, sw4 can regulate the feedback reference from:
+412.5mV to 800mV in 12.5 mV steps. The output voltage thus ranges between
+0.4125 * (1 + R1/R2) V and 0.8 * (1 + R1/R2) V.
+
+Regulators ldo1, ldo2, and ldo4 have a fixed 0.725 V reference and thus output
+0.725 * (1 + R1/R2) V. The ldo3 regulator is fixed to 1.8 V. The ldo1 standby
+regulator can not be disabled and thus should have the regulator-always-on
+property set.

+Broadcom SPI controller
+
+The Broadcom SPI controller is a SPI master found on various SOCs, including
+BRCMSTB (BCM7XXX), Cygnus, NSP and NS2. The Broadcom Master SPI hw IP consits
+of :
+ MSPI : SPI master controller can read and write to a SPI slave device
+ BSPI : Broadcom SPI in combination with the MSPI hw IP provides acceleration
+ for flash reads and be configured to do single, double, quad lane
+ io with 3-byte and 4-byte addressing support.
+
+ Supported Broadcom SoCs have one instance of MSPI+BSPI controller IP.
+ MSPI master can be used wihout BSPI. BRCMSTB SoCs have an additional instance
+ of a MSPI master without the BSPI to use with non flash slave devices that
+ use SPI protocol.
+
+Required properties:
+
+- #address-cells:
+ Must be <1>, as required by generic SPI binding.
+
+- #size-cells:
+ Must be <0>, also as required by generic SPI binding.
+

+ "brcm,spi-bcm-qspi", "brcm,spi-ns2-qspi" : NS2 SoCs
+
+- reg:
+ Define the bases and ranges of the associated I/O address spaces.
+ The required range is MSPI controller registers.
+
+- reg-names:
+ First name does not matter, but must be reserved for the MSPI controller
+ register range as mentioned in 'reg' above, and will typically contain
+ - "bspi_regs": BSPI register range, not required with compatible
+ "spi-brcmstb-mspi"
+ - "mspi_regs": MSPI register range is required for compatible strings
+ - "intr_regs", "intr_status_reg" : Interrupt and status register for
+ NSP, NS2, Cygnus SoC
+
+- interrupts
+ The interrupts used by the MSPI and/or BSPI controller.
+

+Frame Buffer Library
+====================
+
+The frame buffer drivers depend heavily on four data structures. These
+structures are declared in include/linux/fb.h. They are fb_info,
+fb_var_screeninfo, fb_fix_screeninfo and fb_monospecs. The last
+three can be made available to and from userland.
+
+fb_info defines the current state of a particular video card. Inside
+fb_info, there exists a fb_ops structure which is a collection of
+needed functions to make fbdev and fbcon work. fb_info is only visible
+to the kernel.
+
+fb_var_screeninfo is used to describe the features of a video card
+that are user defined. With fb_var_screeninfo, things such as depth
+and the resolution may be defined.
+
+The next structure is fb_fix_screeninfo. This defines the properties
+of a card that are created when a mode is set and can't be changed
+otherwise. A good example of this is the start of the frame buffer
+memory. This "locks" the address of the frame buffer memory, so that it
+cannot be changed or moved.
+
+The last structure is fb_monospecs. In the old API, there was little
+importance for fb_monospecs. This allowed for forbidden things such as
+setting a mode of 800x600 on a fix frequency monitor. With the new API,
+fb_monospecs prevents such things, and if used correctly, can prevent a
+monitor from being cooked. fb_monospecs will not be useful until
+kernels 2.5.x.

+High Speed Synchronous Serial Interface (HSI)
+=============================================
+
+Introduction
+---------------
+
+High Speed Syncronous Interface (HSI) is a fullduplex, low latency protocol,
+that is optimized for die-level interconnect between an Application Processor
+and a Baseband chipset. It has been specified by the MIPI alliance in 2003 and
+implemented by multiple vendors since then.
+
+The HSI interface supports full duplex communication over multiple channels
+(typically 8) and is capable of reaching speeds up to 200 Mbit/s.
+
+The serial protocol uses two signals, DATA and FLAG as combined data and clock
+signals and an additional READY signal for flow control. An additional WAKE
+signal can be used to wakeup the chips from standby modes. The signals are
+commonly prefixed by AC for signals going from the application die to the
+cellular die and CA for signals going the other way around.
+

+
+HSI Subsystem in Linux
+-------------------------
+
+In the Linux kernel the hsi subsystem is supposed to be used for HSI devices.
+The hsi subsystem contains drivers for hsi controllers including support for
+multi-port controllers and provides a generic API for using the HSI ports.
+
+It also contains HSI client drivers, which make use of the generic API to
+implement a protocol used on the HSI interface. These client drivers can
+use an arbitrary number of channels.
+
+hsi-char Device
+------------------
+
+Each port automatically registers a generic client driver called hsi_char,
+which provides a charecter device for userspace representing the HSI port.
+It can be used to communicate via HSI from userspace. Userspace may
+configure the hsi_char device using the following ioctl commands:
+
+HSC_RESET
+ flush the HSI port
+
+HSC_SET_PM
+ enable or disable the client.
+
+HSC_SEND_BREAK
+ send break
+
+HSC_SET_RX

+I\ :sup:`2`\ C and SMBus Subsystem
+==================================
+
+I\ :sup:`2`\ C (or without fancy typography, "I2C") is an acronym for
+the "Inter-IC" bus, a simple bus protocol which is widely used where low
+data rate communications suffice. Since it's also a licensed trademark,
+some vendors use another name (such as "Two-Wire Interface", TWI) for
+the same bus. I2C only needs two signals (SCL for clock, SDA for data),
+conserving board real estate and minimizing signal quality issues. Most
+I2C devices use seven bit addresses, and bus speeds of up to 400 kHz;
+there's a high speed extension (3.4 MHz) that's not yet found wide use.
+I2C is a multi-master bus; open drain signaling is used to arbitrate
+between masters, as well as to handshake and to synchronize clocks from
+slower clients.
+
+The Linux I2C programming interfaces support only the master side of bus
+interactions, not the slave side. The programming interface is
+structured around two kinds of driver, and two kinds of device. An I2C
+"Adapter Driver" abstracts the controller hardware; it binds to a
+physical device (perhaps a PCI device or platform_device) and exposes a
+:c:type:`struct i2c_adapter <i2c_adapter>` representing each
+I2C bus segment it manages. On each I2C bus segment will be I2C devices
+represented by a :c:type:`struct i2c_client <i2c_client>`.
+Those devices will be bound to a :c:type:`struct i2c_driver
+<i2c_driver>`, which should follow the standard Linux driver
+model. (At this writing, a legacy model is more widely used.) There are
+functions to perform various I2C protocol operations; at this writing
+all such functions are usable only from task context.
+
+The System Management Bus (SMBus) is a sibling protocol. Most SMBus
+systems are also I2C conformant. The electrical constraints are tighter
+for SMBus, and it standardizes particular protocol messages and idioms.
+Controllers that support I2C can also support most SMBus operations, but
+SMBus controllers don't support all the protocol options that an I2C
+controller will. There are functions to perform various SMBus protocol
+operations, either using I2C primitives or by issuing SMBus commands to
+i2c_adapter devices which don't support those I2C operations.

+Buffer Sharing and Synchronization
+----------------------------------
+
+The dma-buf subsystem provides the framework for sharing buffers for
+hardware (DMA) access across multiple device drivers and subsystems, and
+for synchronizing asynchronous hardware access.
+
+This is used, for example, by drm "prime" multi-GPU support, but is of
+course not limited to GPU use cases.
+
+The three main components of this are: (1) dma-buf, representing a
+sg_table and exposed to userspace as a file descriptor to allow passing
+between devices, (2) fence, which provides a mechanism to signal when
+one device as finished access, and (3) reservation, which manages the
+shared or exclusive fence(s) associated with the buffer.

+This structure contains fields that describe a particular chip.
+
+A chip exposes one or more PWM signal sources, each of which exposed as
+a :c:type:`struct pwm_device <pwm_device>`. Operations can be
+performed on PWM devices to control the period, duty cycle, polarity and

+
+Note that PWM devices are exclusive resources: they can always only be
+used by one consumer at a time.

+Serial Peripheral Interface (SPI)
+=================================
+
+SPI is the "Serial Peripheral Interface", widely used with embedded
+systems because it is a simple and efficient interface: basically a
+multiplexed shift register. Its three signal wires hold a clock (SCK,
+often in the range of 1-20 MHz), a "Master Out, Slave In" (MOSI) data
+line, and a "Master In, Slave Out" (MISO) data line. SPI is a full
+duplex protocol; for each bit shifted out the MOSI line (one per clock)
+another is shifted in on the MISO line. Those bits are assembled into
+words of various sizes on the way to and from system memory. An
+additional chipselect line is usually active-low (nCS); four signals are
+normally used for each peripheral, plus sometimes an interrupt.
+
+The SPI bus facilities listed here provide a generalized interface to
+declare SPI busses and devices, manage them according to the standard
+Linux driver model, and perform input/output operations. At this time,
+only "master" side interfaces are supported, where Linux talks to SPI
+peripherals and does not implement such a peripheral itself. (Interfaces
+to support implementing SPI slaves would necessarily look different.)
+
+The programming interface is structured around two kinds of driver, and
+two kinds of device. A "Controller Driver" abstracts the controller
+hardware, which may be as simple as a set of GPIO pins or as complex as
+a pair of FIFOs connected to dual DMA engines on the other side of the
+SPI shift register (maximizing throughput). Such drivers bridge between
+whatever bus they sit on (often the platform bus) and SPI, and expose
+the SPI side of their device as a :c:type:`struct spi_master
+<spi_master>`. SPI devices are children of that master,
+represented as a :c:type:`struct spi_device <spi_device>` and
+manufactured from :c:type:`struct spi_board_info
+<spi_board_info>` descriptors which are usually provided by
+board-specific initialization code. A :c:type:`struct spi_driver
+<spi_driver>` is called a "Protocol Driver", and is bound to a
+spi_device using normal driver model calls.
+
+The I/O model is a set of queued messages. Protocol drivers submit one
+or more :c:type:`struct spi_message <spi_message>` objects,
+which are processed and completed asynchronously. (There are synchronous
+wrappers, however.) Messages are built from one or more
+:c:type:`struct spi_transfer <spi_transfer>` objects, each of
+which wraps a full duplex SPI transfer. A variety of protocol tweaking
+options are needed, because different chips adopt very different
+policies for how they use the bits transferred with SPI.

+
+Error handling
+==============
+
+XFS can act differently according to the type of error found during its
+operation. The implementation introduces the following concepts to the error
+handler:
+
+ -failure speed:
+ Defines how fast XFS should propagate an error upwards when a specific
+ error is found during the filesystem operation. It can propagate
+ immediately, after a defined number of retries, after a set time period,
+ or simply retry forever.
+
+ -error classes:
+ Specifies the subsystem the error configuration will apply to, such as
+ metadata IO or memory allocation. Different subsystems will have
+ different error handlers for which behaviour can be configured.
+
+ -error handlers:
+ Defines the behavior for a specific error.
+
+The filesystem behavior during an error can be set via sysfs files. Each
+error handler works independently - the first condition met by an error handler
+for a specific class will cause the error to be propagated rather than reset and
+retried.
+
+The action taken by the filesystem when the error is propagated is context
+dependent - it may cause a shut down in the case of an unrecoverable error,
+it may be reported back to userspace, or it may even be ignored because
+there's nothing useful we can with the error or anyone we can report it to (e.g.
+during unmount).
+
+The configuration files are organized into the following hierarchy for each
+mounted filesystem:
+
+ /sys/fs/xfs/<dev>/error/<class>/<error>/
+
+Where:
+ <dev>
+ The short device name of the mounted filesystem. This is the same device
+ name that shows up in XFS kernel error messages as "XFS(<dev>): ..."
+
+ <class>
+ The subsystem the error configuration belongs to. As of 4.9, the defined
+ classes are:
+
+ - "metadata": applies metadata buffer write IO
+
+ <error>
+ The individual error handler configurations.
+
+
+Each filesystem has "global" error configuration options defined in their top
+level directory:
+
+ /sys/fs/xfs/<dev>/error/
+
+ fail_at_unmount (Min: 0 Default: 1 Max: 1)
+ Defines the filesystem error behavior at unmount time.
+
+ If set to a value of 1, XFS will override all other error configurations
+ during unmount and replace them with "immediate fail" characteristics.
+ i.e. no retries, no retry timeout. This will always allow unmount to
+ succeed when there are persistent errors present.
+
+ If set to 0, the configured retry behaviour will continue until all
+ retries and/or timeouts have been exhausted. This will delay unmount
+ completion when there are persistent errors, and it may prevent the
+ filesystem from ever unmounting fully in the case of "retry forever"
+ handler configurations.
+
+ Note: there is no guarantee that fail_at_unmount can be set whilst an
+ unmount is in progress. It is possible that the sysfs entries are
+ removed by the unmounting filesystem before a "retry forever" error
+ handler configuration causes unmount to hang, and hence the filesystem
+ must be configured appropriately before unmount begins to prevent
+ unmount hangs.
+
+Each filesystem has specific error class handlers that define the error
+propagation behaviour for specific errors. There is also a "default" error
+handler defined, which defines the behaviour for all errors that don't have
+specific handlers defined. Where multiple retry constraints are configuredi for
+a single error, the first retry configuration that expires will cause the error
+to be propagated. The handler configurations are found in the directory:
+
+ /sys/fs/xfs/<dev>/error/<class>/<error>/
+
+ max_retries (Min: -1 Default: Varies Max: INTMAX)
+ Defines the allowed number of retries of a specific error before
+ the filesystem will propagate the error. The retry count for a given
+ error context (e.g. a specific metadata buffer) is reset every time
+ there is a successful completion of the operation.
+
+ Setting the value to "-1" will cause XFS to retry forever for this
+ specific error.
+
+ Setting the value to "0" will cause XFS to fail immediately when the
+ specific error is reported.
+
+ Setting the value to "N" (where 0 < N < Max) will make XFS retry the
+ operation "N" times before propagating the error.
+
+ retry_timeout_seconds (Min: -1 Default: Varies Max: 1 day)
+ Define the amount of time (in seconds) that the filesystem is
+ allowed to retry its operations when the specific error is
+ found.
+
+ Setting the value to "-1" will allow XFS to retry forever for this
+ specific error.
+
+ Setting the value to "0" will cause XFS to fail immediately when the
+ specific error is reported.
+
+ Setting the value to "N" (where 0 < N < Max) will allow XFS to retry the
+ operation for up to "N" seconds before propagating the error.
+
+Note: The default behaviour for a specific error handler is dependent on both
+the class and error context. For example, the default values for
+"metadata/ENODEV" are "0" rather than "-1" so that this error handler defaults
+to "fail immediately" behaviour. This is done because ENODEV is a fatal,
+unrecoverable error no matter how many times the metadata IO is retried.

-1. Introduction
-===============
-
-gcov profiling kernel support enables the use of GCC's coverage testing
-tool gcov [1] with the Linux kernel. Coverage data of a running kernel
-is exported in gcov-compatible format via the "gcov" debugfs directory.
-To get coverage data for a specific file, change to the kernel build
-directory and use gcov with the -o option as follows (requires root):
-
-# cd /tmp/linux-out
-# gcov -o /sys/kernel/debug/gcov/tmp/linux-out/kernel spinlock.c
-
-This will create source code files annotated with execution counts
-in the current directory. In addition, graphical gcov front-ends such
-as lcov [2] can be used to automate the process of collecting data
-for the entire kernel and provide coverage overviews in HTML format.
-
-Possible uses:
-
-* debugging (has this line been reached at all?)
-* test improvement (how do I change my test to cover these lines?)
-* minimizing kernel configurations (do I need this option if the
- associated code is never run?)
-
---
-
-[1] http://gcc.gnu.org/onlinedocs/gcc/Gcov.html
-[2] http://ltp.sourceforge.net/coverage/lcov.php
-
-
-2. Preparation
-==============
-
-Configure the kernel with:
-
- CONFIG_DEBUG_FS=y
- CONFIG_GCOV_KERNEL=y
-
-select the gcc's gcov format, default is autodetect based on gcc version:
-
- CONFIG_GCOV_FORMAT_AUTODETECT=y
-
-and to get coverage data for the entire kernel:
-
- CONFIG_GCOV_PROFILE_ALL=y
-
-Note that kernels compiled with profiling flags will be significantly
-larger and run slower. Also CONFIG_GCOV_PROFILE_ALL may not be supported
-on all architectures.
-
-Profiling data will only become accessible once debugfs has been
-mounted:
-
- mount -t debugfs none /sys/kernel/debug
-
-
-3. Customization
-================
-
-To enable profiling for specific files or directories, add a line
-similar to the following to the respective kernel Makefile:
-
- For a single file (e.g. main.o):
- GCOV_PROFILE_main.o := y
-
- For all files in one directory:
- GCOV_PROFILE := y
-
-To exclude files from being profiled even when CONFIG_GCOV_PROFILE_ALL
-is specified, use:
-
- GCOV_PROFILE_main.o := n
- and:
- GCOV_PROFILE := n
-
-Only files which are linked to the main kernel image or are compiled as
-kernel modules are supported by this mechanism.
-
-
-4. Files
-========
-
-The gcov kernel support creates the following files in debugfs:
-
- /sys/kernel/debug/gcov
- Parent directory for all gcov-related files.
-
- /sys/kernel/debug/gcov/reset
- Global reset file: resets all coverage data to zero when
- written to.
-
- /sys/kernel/debug/gcov/path/to/compile/dir/file.gcda
- The actual gcov data file as understood by the gcov
- tool. Resets file coverage data to zero when written to.
-
- /sys/kernel/debug/gcov/path/to/compile/dir/file.gcno
- Symbolic link to a static data file required by the gcov
- tool. This file is generated by gcc when compiling with
- option -ftest-coverage.
-
-
-5. Modules
-==========
-
-Kernel modules may contain cleanup code which is only run during
-module unload time. The gcov mechanism provides a means to collect
-coverage data for such code by keeping a copy of the data associated
-with the unloaded module. This data remains available through debugfs.
-Once the module is loaded again, the associated coverage counters are
-initialized with the data from its previous instantiation.
-
-This behavior can be deactivated by specifying the gcov_persist kernel
-parameter:
-
- gcov_persist=0
-
-At run-time, a user can also choose to discard data for an unloaded
-module by writing to its data file or the global reset file.
-
-
-6. Separated build and test machines
-====================================
-
-The gcov kernel profiling infrastructure is designed to work out-of-the
-box for setups where kernels are built and run on the same machine. In
-cases where the kernel runs on a separate machine, special preparations
-must be made, depending on where the gcov tool is used:
-
-a) gcov is run on the TEST machine
-
-The gcov tool version on the test machine must be compatible with the
-gcc version used for kernel build. Also the following files need to be
-copied from build to test machine:
-
-from the source tree:
- - all C source files + headers
-
-from the build tree:
- - all C source files + headers
- - all .gcda and .gcno files
- - all links to directories
-
-It is important to note that these files need to be placed into the
-exact same file system location on the test machine as on the build
-machine. If any of the path components is symbolic link, the actual
-directory needs to be used instead (due to make's CURDIR handling).
-
-b) gcov is run on the BUILD machine
-
-The following files need to be copied after each test case from test
-to build machine:
-
-from the gcov directory in sysfs:
- - all .gcda files
- - all links to .gcno files
-
-These files can be copied to any location on the build machine. gcov
-must then be called with the -o option pointing to that directory.
-
-Example directory setup on the build machine:
-
- /tmp/linux: kernel source tree
- /tmp/out: kernel build directory as specified by make O=
- /tmp/coverage: location of the files copied from the test machine
-
- [user@build] cd /tmp/out
- [user@build] gcov -o /tmp/coverage/tmp/out/init main.c
-
-
-7. Troubleshooting
-==================
-
-Problem: Compilation aborts during linker step.
-Cause: Profiling flags are specified for source files which are not
- linked to the main kernel or which are linked by a custom
- linker procedure.
-Solution: Exclude affected source files from profiling by specifying
- GCOV_PROFILE := n or GCOV_PROFILE_basename.o := n in the
- corresponding Makefile.
-
-Problem: Files copied from sysfs appear empty or incomplete.
-Cause: Due to the way seq_file works, some tools such as cp or tar
- may not correctly copy files from sysfs.
-Solution: Use 'cat' to read .gcda files and 'cp -d' to copy links.
- Alternatively use the mechanism shown in Appendix B.

-Debugging kernel and modules via gdb
-====================================
-
-The kernel debugger kgdb, hypervisors like QEMU or JTAG-based hardware
-interfaces allow to debug the Linux kernel and its modules during runtime
-using gdb. Gdb comes with a powerful scripting interface for python. The
-kernel provides a collection of helper scripts that can simplify typical
-kernel debugging steps. This is a short tutorial about how to enable and use
-them. It focuses on QEMU/KVM virtual machines as target, but the examples can
-be transferred to the other gdb stubs as well.
-
-
-Requirements
-------------
-
- o gdb 7.2+ (recommended: 7.4+) with python support enabled (typically true
- for distributions)
-
-
-Setup
------
-
- o Create a virtual Linux machine for QEMU/KVM (see www.linux-kvm.org and
- www.qemu.org for more details). For cross-development,
- http://landley.net/aboriginal/bin keeps a pool of machine images and
- toolchains that can be helpful to start from.
-
- o Build the kernel with CONFIG_GDB_SCRIPTS enabled, but leave
- CONFIG_DEBUG_INFO_REDUCED off. If your architecture supports
- CONFIG_FRAME_POINTER, keep it enabled.
-
- o Install that kernel on the guest.
-
- Alternatively, QEMU allows to boot the kernel directly using -kernel,
- -append, -initrd command line switches. This is generally only useful if
- you do not depend on modules. See QEMU documentation for more details on
- this mode.
-
- o Enable the gdb stub of QEMU/KVM, either
- - at VM startup time by appending "-s" to the QEMU command line
- or
- - during runtime by issuing "gdbserver" from the QEMU monitor
- console
-
- o cd /path/to/linux-build
-
- o Start gdb: gdb vmlinux
-
- Note: Some distros may restrict auto-loading of gdb scripts to known safe
- directories. In case gdb reports to refuse loading vmlinux-gdb.py, add
-
- add-auto-load-safe-path /path/to/linux-build
-
- to ~/.gdbinit. See gdb help for more details.
-
- o Attach to the booted guest:
- (gdb) target remote :1234
-
-
-Examples of using the Linux-provided gdb helpers
-------------------------------------------------
-
- o Load module (and main kernel) symbols:
- (gdb) lx-symbols
- loading vmlinux
- scanning for modules in /home/user/linux/build
- loading @0xffffffffa0020000: /home/user/linux/build/net/netfilter/xt_tcpudp.ko
- loading @0xffffffffa0016000: /home/user/linux/build/net/netfilter/xt_pkttype.ko
- loading @0xffffffffa0002000: /home/user/linux/build/net/netfilter/xt_limit.ko

- loading @0xffffffffa003c000: /home/user/linux/build/fs/fuse/fuse.ko
- ...
- loading @0xffffffffa0000000: /home/user/linux/build/drivers/ata/ata_generic.ko
-
- o Set a breakpoint on some not yet loaded module function, e.g.:
- (gdb) b btrfs_init_sysfs
- Function "btrfs_init_sysfs" not defined.
- Make breakpoint pending on future shared library load? (y or [n]) y
- Breakpoint 1 (btrfs_init_sysfs) pending.
-
- o Continue the target
- (gdb) c
-
- o Load the module on the target and watch the symbols being loaded as well as
- the breakpoint hit:
- loading @0xffffffffa0034000: /home/user/linux/build/lib/libcrc32c.ko
- loading @0xffffffffa0050000: /home/user/linux/build/lib/lzo/lzo_compress.ko
- loading @0xffffffffa006e000: /home/user/linux/build/lib/zlib_deflate/zlib_deflate.ko
- loading @0xffffffffa01b1000: /home/user/linux/build/fs/btrfs/btrfs.ko
-
- Breakpoint 1, btrfs_init_sysfs () at /home/user/linux/fs/btrfs/sysfs.c:36
- 36 btrfs_kset = kset_create_and_add("btrfs", NULL, fs_kobj);
-
- o Dump the log buffer of the target kernel:
- (gdb) lx-dmesg
- [ 0.000000] Initializing cgroup subsys cpuset
- [ 0.000000] Initializing cgroup subsys cpu
- [ 0.000000] Linux version 3.8.0-rc4-dbg+ (...

- ....
-
- o Examine fields of the current task struct:
- (gdb) p $lx_current().pid
- $1 = 4998
- (gdb) p $lx_current().comm
- $2 = "modprobe\000\000\000\000\000\000\000"
-
- o Make use of the per-cpu function for the current or a specified CPU:
- (gdb) p $lx_per_cpu("runqueues").nr_running
- $3 = 1
- (gdb) p $lx_per_cpu("runqueues", 2).nr_running
- $4 = 0
-
- o Dig into hrtimers using the container_of helper:
- (gdb) set $next = $lx_per_cpu("hrtimer_bases").clock_base[0].active.next
- (gdb) p *$container_of($next, "struct hrtimer", "node")

-HSI - High-speed Synchronous Serial Interface
-
-1. Introduction
-~~~~~~~~~~~~~~~
-
-High Speed Syncronous Interface (HSI) is a fullduplex, low latency protocol,
-that is optimized for die-level interconnect between an Application Processor
-and a Baseband chipset. It has been specified by the MIPI alliance in 2003 and
-implemented by multiple vendors since then.
-
-The HSI interface supports full duplex communication over multiple channels
-(typically 8) and is capable of reaching speeds up to 200 Mbit/s.
-
-The serial protocol uses two signals, DATA and FLAG as combined data and clock
-signals and an additional READY signal for flow control. An additional WAKE
-signal can be used to wakeup the chips from standby modes. The signals are
-commonly prefixed by AC for signals going from the application die to the
-cellular die and CA for signals going the other way around.

-2. HSI Subsystem in Linux
-~~~~~~~~~~~~~~~~~~~~~~~~~
-
-In the Linux kernel the hsi subsystem is supposed to be used for HSI devices.
-The hsi subsystem contains drivers for hsi controllers including support for
-multi-port controllers and provides a generic API for using the HSI ports.
-
-It also contains HSI client drivers, which make use of the generic API to
-implement a protocol used on the HSI interface. These client drivers can
-use an arbitrary number of channels.
-
-3. hsi-char Device
-~~~~~~~~~~~~~~~~~~
-
-Each port automatically registers a generic client driver called hsi_char,
-which provides a charecter device for userspace representing the HSI port.
-It can be used to communicate via HSI from userspace. Userspace may
-configure the hsi_char device using the following ioctl commands:
-
-* HSC_RESET:
- - flush the HSI port
-
-* HSC_SET_PM
- - enable or disable the client.
-
-* HSC_SEND_BREAK
- - send break
-
-* HSC_SET_RX
- - set RX configuration
-
-* HSC_GET_RX
- - get RX configuration
-
-* HSC_SET_TX

+
+The hwmon_chip_info structure looks as follows.
+
+struct hwmon_chip_info {
+ const struct hwmon_ops *ops;
+ const struct hwmon_channel_info **info;
+};
+
+It contains the following fields:
+
+* ops: Pointer to device operations.
+* info: NULL-terminated list of device channel descriptors.
+

+
+struct hwmon_ops {
+ umode_t (*is_visible)(const void *, enum hwmon_sensor_types type,
+ u32 attr, int);
+ int (*read)(struct device *, enum hwmon_sensor_types type,

+
+It defines the following operations.
+
+* is_visible: Pointer to a function to return the file mode for each supported
+ attribute. This function is mandatory.
+

+ is optional, but must be provided if any readable attributes exist.
+
+* write: Pointer to a function for writing a value to the chip. This function is
+ optional, but must be provided if any writeable attributes exist.

+ u32 *config;
+};
+
+It contains following fields:
+
+* type: The hardware monitoring sensor type.
+ Supported sensor types are

+ * hwmon_fan Fan speed sensor
+ * hwmon_pwm PWM control
+
+* config: Pointer to a 0-terminated list of configuration values for each
+ sensor of the given type. Each value is a combination of bit values
+ describing the attributes supposed by a single sensor.
+
+As an example, here is the complete description file for a LM75 compatible
+sensor chip. The chip has a single temperature sensor. The driver wants to
+register with the thermal subsystem (HWMON_C_REGISTER_TZ), and it supports
+the update_interval attribute (HWMON_C_UPDATE_INTERVAL). The chip supports
+reading the temperature (HWMON_T_INPUT), it has a maximum temperature
+register (HWMON_T_MAX) as well as a maximum temperature hysteresis register
+(HWMON_T_MAX_HYST).

+ attr: Attribute identifier associated with a specific attribute.
+ For example, the attribute value for HWMON_T_INPUT would be
+ hwmon_temp_input. For complete mappings of bit fields to
+ attribute values please see include/linux/hwmon.h.
+ channel:The sensor channel number.
+
+Return value:
+ The file mode for this attribute. Typically, this will be 0 (the
+ attribute will not be created), S_IRUGO, or 'S_IRUGO | S_IWUSR'.
+
+int read_func(struct device *dev, enum hwmon_sensor_types type,
+ u32 attr, int channel, long *val)
+
+Parameters:
+ dev: Pointer to the hardware monitoring device.
+ type: The sensor type.
+ attr: Attribute identifier associated with a specific attribute.
+ For example, the attribute value for HWMON_T_INPUT would be
+ hwmon_temp_input. For complete mappings please see
+ include/linux/hwmon.h.
+ channel:The sensor channel number.
+ val: Pointer to attribute value.
+
+Return value:
+ 0 on success, a negative error number otherwise.
+
+int write_func(struct device *dev, enum hwmon_sensor_types type,
+ u32 attr, int channel, long val)
+
+Parameters:
+ dev: Pointer to the hardware monitoring device.
+ type: The sensor type.
+ attr: Attribute identifier associated with a specific attribute.
+ For example, the attribute value for HWMON_T_INPUT would be
+ hwmon_temp_input. For complete mappings please see
+ include/linux/hwmon.h.
+ channel:The sensor channel number.
+ val: The value to write to the chip.
+
+Return value:
+ 0 on success, a negative error number otherwise.
+
+
+Driver-provided sysfs attributes
+--------------------------------
+
+If the hardware monitoring device is registered with
+hwmon_device_register_with_info or devm_hwmon_device_register_with_info,
+it is most likely not necessary to provide sysfs attributes. Only non-standard
+sysfs attributes need to be provided when one of those registration functions
+is used.
The header file linux/hwmon-sysfs.h provides a number of useful macros to
declare and use hardware monitoring sysfs attributes.

-KernelAddressSanitizer (KASAN)
-==============================
-
-0. Overview
-===========
-
-KernelAddressSANitizer (KASAN) is a dynamic memory error detector. It provides
-a fast and comprehensive solution for finding use-after-free and out-of-bounds
-bugs.
-
-KASAN uses compile-time instrumentation for checking every memory access,
-therefore you will need a GCC version 4.9.2 or later. GCC 5.0 or later is
-required for detection of out-of-bounds accesses to stack or global variables.
-
-Currently KASAN is supported only for x86_64 architecture.
-
-1. Usage
-========
-
-To enable KASAN configure kernel with:
-
- CONFIG_KASAN = y
-
-and choose between CONFIG_KASAN_OUTLINE and CONFIG_KASAN_INLINE. Outline and
-inline are compiler instrumentation types. The former produces smaller binary
-the latter is 1.1 - 2 times faster. Inline instrumentation requires a GCC
-version 5.0 or later.
-
-KASAN works with both SLUB and SLAB memory allocators.
-For better bug detection and nicer reporting, enable CONFIG_STACKTRACE.
-
-To disable instrumentation for specific files or directories, add a line
-similar to the following to the respective kernel Makefile:
-
- For a single file (e.g. main.o):
- KASAN_SANITIZE_main.o := n
-
- For all files in one directory:
- KASAN_SANITIZE := n
-

-
-The header of the report discribe what kind of bug happened and what kind of
-access caused it. It's followed by the description of the accessed slub object
-(see 'SLUB Debug output' section in Documentation/vm/slub.txt for details) and
-the description of the accessed memory page.
-
-In the last section the report shows memory state around the accessed address.
-Reading this part requires some understanding of how KASAN works.
-
-The state of each 8 aligned bytes of memory is encoded in one shadow byte.
-Those 8 bytes can be accessible, partially accessible, freed or be a redzone.
-We use the following encoding for each shadow byte: 0 means that all 8 bytes
-of the corresponding memory region are accessible; number N (1 <= N <= 7) means
-that the first N bytes are accessible, and other (8 - N) bytes are not;
-any negative value indicates that the entire 8-byte word is inaccessible.
-We use different negative values to distinguish between different kinds of
-inaccessible memory like redzones or freed memory (see mm/kasan/kasan.h).
-
-In the report above the arrows point to the shadow byte 03, which means that
-the accessed address is partially accessible.
-
-
-2. Implementation details
-=========================
-
-From a high level, our approach to memory error detection is similar to that
-of kmemcheck: use shadow memory to record whether each byte of memory is safe
-to access, and use compile-time instrumentation to check shadow memory on each
-memory access.
-
-AddressSanitizer dedicates 1/8 of kernel memory to its shadow memory
-(e.g. 16TB to cover 128TB on x86_64) and uses direct mapping with a scale and
-offset to translate a memory address to its corresponding shadow address.
-
-Here is the function which translates an address to its corresponding shadow
-address:
-
-static inline void *kasan_mem_to_shadow(const void *addr)
-{
- return ((unsigned long)addr >> KASAN_SHADOW_SCALE_SHIFT)
- + KASAN_SHADOW_OFFSET;
-}
-
-where KASAN_SHADOW_SCALE_SHIFT = 3.
-
-Compile-time instrumentation used for checking memory accesses. Compiler inserts
-function calls (__asan_load*(addr), __asan_store*(addr)) before each memory
-access of size 1, 2, 4, 8 or 16. These functions check whether memory access is
-valid or not by checking corresponding shadow memory.
-
-GCC 5.0 has possibility to perform inline instrumentation. Instead of making
-function calls GCC directly inserts the code to check the shadow memory.
-This option significantly enlarges kernel but it gives x1.1-x2 performance
-boost over outline instrumented kernel.

-kcov: code coverage for fuzzing
-===============================
-
-kcov exposes kernel code coverage information in a form suitable for coverage-
-guided fuzzing (randomized testing). Coverage data of a running kernel is
-exported via the "kcov" debugfs file. Coverage collection is enabled on a task
-basis, and thus it can capture precise coverage of a single system call.
-
-Note that kcov does not aim to collect as much coverage as possible. It aims
-to collect more or less stable coverage that is function of syscall inputs.
-To achieve this goal it does not collect coverage in soft/hard interrupts
-and instrumentation of some inherently non-deterministic parts of kernel is
-disbled (e.g. scheduler, locking).
-
-Usage:
-======
-
-Configure kernel with:
-
- CONFIG_KCOV=y
-
-CONFIG_KCOV requires gcc built on revision 231296 or later.
-Profiling data will only become accessible once debugfs has been mounted:
-
- mount -t debugfs none /sys/kernel/debug
-
-The following program demonstrates kcov usage from within a test program:
-
-#include <stdio.h>
-#include <stddef.h>
-#include <stdint.h>
-#include <stdlib.h>
-#include <sys/types.h>

- perror("munmap"), exit(1);
- if (close(fd))
- perror("close"), exit(1);
- return 0;
-}
-
-After piping through addr2line output of the program looks as follows:
-
-SyS_read
-fs/read_write.c:562
-__fdget_pos
-fs/file.c:774
-__fget_light
-fs/file.c:746
-__fget_light

-__fget_light
-fs/file.c:760
-__fdget_pos
-fs/file.c:784
-SyS_read
-fs/read_write.c:562
-
-If a program needs to collect coverage from several threads (independently),
-it needs to open /sys/kernel/debug/kcov in each thread separately.
-
-The interface is fine-grained to allow efficient forking of test processes.
-That is, a parent process opens /sys/kernel/debug/kcov, enables trace mode,
-mmaps coverage buffer and then forks child processes in a loop. Child processes
-only need to enable coverage (disable happens automatically on thread end).

+ :Description: From the Introduction: "I/O Event handling is about
+ how your Operating System allows you to manage a large number of
+ open files (file descriptors in UNIX/POSIX, or FDs) in your
+ application. You want the OS to notify you when FDs become active
+ (have data ready to be read or are ready for writing). Ideally you
+ want a mechanism that is scalable. This means a large number of
+ inactive FDs cost very little in memory and CPU time to manage".

-0. Introduction
-===============
-
-kmemcheck is a debugging feature for the Linux Kernel. More specifically, it
-is a dynamic checker that detects and warns about some uses of uninitialized
-memory.
-
-Userspace programmers might be familiar with Valgrind's memcheck. The main
-difference between memcheck and kmemcheck is that memcheck works for userspace
-programs only, and kmemcheck works for the kernel only. The implementations
-are of course vastly different. Because of this, kmemcheck is not as accurate
-as memcheck, but it turns out to be good enough in practice to discover real
-programmer errors that the compiler is not able to find through static
-analysis.
-
-Enabling kmemcheck on a kernel will probably slow it down to the extent that
-the machine will not be usable for normal workloads such as e.g. an
-interactive desktop. kmemcheck will also cause the kernel to use about twice
-as much memory as normal. For this reason, kmemcheck is strictly a debugging
-feature.
-
-
-1. Downloading
-==============
-
-As of version 2.6.31-rc1, kmemcheck is included in the mainline kernel.
-
-
-2. Configuring and compiling
-============================
-
-kmemcheck only works for the x86 (both 32- and 64-bit) platform. A number of
-configuration variables must have specific settings in order for the kmemcheck
-menu to even appear in "menuconfig". These are:
-
- o CONFIG_CC_OPTIMIZE_FOR_SIZE=n
-
- This option is located under "General setup" / "Optimize for size".
-
- Without this, gcc will use certain optimizations that usually lead to
- false positive warnings from kmemcheck. An example of this is a 16-bit
- field in a struct, where gcc may load 32 bits, then discard the upper
- 16 bits. kmemcheck sees only the 32-bit load, and may trigger a
- warning for the upper 16 bits (if they're uninitialized).
-
- o CONFIG_SLAB=y or CONFIG_SLUB=y
-
- This option is located under "General setup" / "Choose SLAB
- allocator".
-
- o CONFIG_FUNCTION_TRACER=n
-
- This option is located under "Kernel hacking" / "Tracers" / "Kernel
- Function Tracer"
-
- When function tracing is compiled in, gcc emits a call to another
- function at the beginning of every function. This means that when the
- page fault handler is called, the ftrace framework will be called
- before kmemcheck has had a chance to handle the fault. If ftrace then
- modifies memory that was tracked by kmemcheck, the result is an
- endless recursive page fault.
-
- o CONFIG_DEBUG_PAGEALLOC=n
-
- This option is located under "Kernel hacking" / "Memory Debugging"
- / "Debug page memory allocations".
-
-In addition, I highly recommend turning on CONFIG_DEBUG_INFO=y. This is also
-located under "Kernel hacking". With this, you will be able to get line number
-information from the kmemcheck warnings, which is extremely valuable in
-debugging a problem. This option is not mandatory, however, because it slows
-down the compilation process and produces a much bigger kernel image.
-
-Now the kmemcheck menu should be visible (under "Kernel hacking" / "Memory
-Debugging" / "kmemcheck: trap use of uninitialized memory"). Here follows
-a description of the kmemcheck configuration variables:
-
- o CONFIG_KMEMCHECK
-
- This must be enabled in order to use kmemcheck at all...
-
- o CONFIG_KMEMCHECK_[DISABLED | ENABLED | ONESHOT]_BY_DEFAULT
-
- This option controls the status of kmemcheck at boot-time. "Enabled"
- will enable kmemcheck right from the start, "disabled" will boot the
- kernel as normal (but with the kmemcheck code compiled in, so it can
- be enabled at run-time after the kernel has booted), and "one-shot" is
- a special mode which will turn kmemcheck off automatically after
- detecting the first use of uninitialized memory.
-
- If you are using kmemcheck to actively debug a problem, then you
- probably want to choose "enabled" here.
-
- The one-shot mode is mostly useful in automated test setups because it
- can prevent floods of warnings and increase the chances of the machine
- surviving in case something is really wrong. In other cases, the one-
- shot mode could actually be counter-productive because it would turn
- itself off at the very first error -- in the case of a false positive
- too -- and this would come in the way of debugging the specific
- problem you were interested in.
-
- If you would like to use your kernel as normal, but with a chance to
- enable kmemcheck in case of some problem, it might be a good idea to
- choose "disabled" here. When kmemcheck is disabled, most of the run-
- time overhead is not incurred, and the kernel will be almost as fast
- as normal.
-
- o CONFIG_KMEMCHECK_QUEUE_SIZE
-
- Select the maximum number of error reports to store in an internal
- (fixed-size) buffer. Since errors can occur virtually anywhere and in
- any context, we need a temporary storage area which is guaranteed not
- to generate any other page faults when accessed. The queue will be
- emptied as soon as a tasklet may be scheduled. If the queue is full,
- new error reports will be lost.
-
- The default value of 64 is probably fine. If some code produces more
- than 64 errors within an irqs-off section, then the code is likely to
- produce many, many more, too, and these additional reports seldom give
- any more information (the first report is usually the most valuable
- anyway).
-
- This number might have to be adjusted if you are not using serial
- console or similar to capture the kernel log. If you are using the
- "dmesg" command to save the log, then getting a lot of kmemcheck
- warnings might overflow the kernel log itself, and the earlier reports
- will get lost in that way instead. Try setting this to 10 or so on
- such a setup.
-
- o CONFIG_KMEMCHECK_SHADOW_COPY_SHIFT
-
- Select the number of shadow bytes to save along with each entry of the
- error-report queue. These bytes indicate what parts of an allocation
- are initialized, uninitialized, etc. and will be displayed when an
- error is detected to help the debugging of a particular problem.
-
- The number entered here is actually the logarithm of the number of
- bytes that will be saved. So if you pick for example 5 here, kmemcheck
- will save 2^5 = 32 bytes.
-
- The default value should be fine for debugging most problems. It also
- fits nicely within 80 columns.
-
- o CONFIG_KMEMCHECK_PARTIAL_OK
-
- This option (when enabled) works around certain GCC optimizations that
- produce 32-bit reads from 16-bit variables where the upper 16 bits are
- thrown away afterwards.
-
- The default value (enabled) is recommended. This may of course hide
- some real errors, but disabling it would probably produce a lot of
- false positives.
-
- o CONFIG_KMEMCHECK_BITOPS_OK
-
- This option silences warnings that would be generated for bit-field
- accesses where not all the bits are initialized at the same time. This
- may also hide some real bugs.
-
- This option is probably obsolete, or it should be replaced with
- the kmemcheck-/bitfield-annotations for the code in question. The
- default value is therefore fine.
-
-Now compile the kernel as usual.
-
-
-3. How to use
-=============
-
-3.1. Booting
-============
-
-First some information about the command-line options. There is only one
-option specific to kmemcheck, and this is called "kmemcheck". It can be used
-to override the default mode as chosen by the CONFIG_KMEMCHECK_*_BY_DEFAULT
-option. Its possible settings are:
-
- o kmemcheck=0 (disabled)
- o kmemcheck=1 (enabled)
- o kmemcheck=2 (one-shot mode)
-
-If SLUB debugging has been enabled in the kernel, it may take precedence over
-kmemcheck in such a way that the slab caches which are under SLUB debugging
-will not be tracked by kmemcheck. In order to ensure that this doesn't happen
-(even though it shouldn't by default), use SLUB's boot option "slub_debug",
-like this: slub_debug=-
-
-In fact, this option may also be used for fine-grained control over SLUB vs.
-kmemcheck. For example, if the command line includes "kmemcheck=1
-slub_debug=,dentry", then SLUB debugging will be used only for the "dentry"
-slab cache, and with kmemcheck tracking all the other caches. This is advanced
-usage, however, and is not generally recommended.
-
-
-3.2. Run-time enable/disable
-============================
-
-When the kernel has booted, it is possible to enable or disable kmemcheck at
-run-time. WARNING: This feature is still experimental and may cause false
-positive warnings to appear. Therefore, try not to use this. If you find that
-it doesn't work properly (e.g. you see an unreasonable amount of warnings), I
-will be happy to take bug reports.
-
-Use the file /proc/sys/kernel/kmemcheck for this purpose, e.g.:
-
- $ echo 0 > /proc/sys/kernel/kmemcheck # disables kmemcheck
-
-The numbers are the same as for the kmemcheck= command-line option.
-
-
-3.3. Debugging
-==============
-
-A typical report will look something like this:
-
-WARNING: kmemcheck: Caught 32-bit read from uninitialized memory (ffff88003e4a2024)

-
-The single most valuable information in this report is the RIP (or EIP on 32-
-bit) value. This will help us pinpoint exactly which instruction that caused
-the warning.
-
-If your kernel was compiled with CONFIG_DEBUG_INFO=y, then all we have to do
-is give this address to the addr2line program, like this:
-
- $ addr2line -e vmlinux -i ffffffff8104ede8
- arch/x86/include/asm/string_64.h:12
- include/asm-generic/siginfo.h:287
- kernel/signal.c:380
- kernel/signal.c:410
-
-The "-e vmlinux" tells addr2line which file to look in. IMPORTANT: This must
-be the vmlinux of the kernel that produced the warning in the first place! If
-not, the line number information will almost certainly be wrong.
-
-The "-i" tells addr2line to also print the line numbers of inlined functions.
-In this case, the flag was very important, because otherwise, it would only
-have printed the first line, which is just a call to memcpy(), which could be
-called from a thousand places in the kernel, and is therefore not very useful.
-These inlined functions would not show up in the stack trace above, simply
-because the kernel doesn't load the extra debugging information. This
-technique can of course be used with ordinary kernel oopses as well.
-
-In this case, it's the caller of memcpy() that is interesting, and it can be
-found in include/asm-generic/siginfo.h, line 287:
-
-281 static inline void copy_siginfo(struct siginfo *to, struct siginfo *from)
-282 {
-283 if (from->si_code < 0)
-284 memcpy(to, from, sizeof(*to));
-285 else
-286 /* _sigchld is currently the largest know union member */
-287 memcpy(to, from, __ARCH_SI_PREAMBLE_SIZE + sizeof(from->_sifields._sigchld));
-288 }
-
-Since this was a read (kmemcheck usually warns about reads only, though it can
-warn about writes to unallocated or freed memory as well), it was probably the
-"from" argument which contained some uninitialized bytes. Following the chain
-of calls, we move upwards to see where "from" was allocated or initialized,
-kernel/signal.c, line 380:
-
-359 static void collect_signal(int sig, struct sigpending *list, siginfo_t *info)
-360 {
-...
-367 list_for_each_entry(q, &list->list, list) {
-368 if (q->info.si_signo == sig) {
-369 if (first)
-370 goto still_pending;
-371 first = q;
-...
-377 if (first) {
-378 still_pending:
-379 list_del_init(&first->list);
-380 copy_siginfo(info, &first->info);
-381 __sigqueue_free(first);
-...
-392 }
-393 }
-
-Here, it is &first->info that is being passed on to copy_siginfo(). The
-variable "first" was found on a list -- passed in as the second argument to
-collect_signal(). We continue our journey through the stack, to figure out
-where the item on "list" was allocated or initialized. We move to line 410:
-
-395 static int __dequeue_signal(struct sigpending *pending, sigset_t *mask,
-396 siginfo_t *info)
-397 {
-...
-410 collect_signal(sig, pending, info);
-...
-414 }
-
-Now we need to follow the "pending" pointer, since that is being passed on to
-collect_signal() as "list". At this point, we've run out of lines from the
-"addr2line" output. Not to worry, we just paste the next addresses from the
-kmemcheck stack dump, i.e.:
-
- [<ffffffff8104f04e>] dequeue_signal+0x8e/0x170
- [<ffffffff81050bd8>] get_signal_to_deliver+0x98/0x390
- [<ffffffff8100b87d>] do_notify_resume+0xad/0x7d0
- [<ffffffff8100c7b5>] int_signal+0x12/0x17
-
- $ addr2line -e vmlinux -i ffffffff8104f04e ffffffff81050bd8 \
- ffffffff8100b87d ffffffff8100c7b5
- kernel/signal.c:446
- kernel/signal.c:1806
- arch/x86/kernel/signal.c:805
- arch/x86/kernel/signal.c:871
- arch/x86/kernel/entry_64.S:694
-
-Remember that since these addresses were found on the stack and not as the
-RIP value, they actually point to the _next_ instruction (they are return
-addresses). This becomes obvious when we look at the code for line 446:
-
-422 int dequeue_signal(struct task_struct *tsk, sigset_t *mask, siginfo_t *info)
-423 {
-...
-431 signr = __dequeue_signal(&tsk->signal->shared_pending,
-432 mask, info);
-433 /*
-434 * itimer signal ?
-435 *
-436 * itimers are process shared and we restart periodic
-437 * itimers in the signal delivery path to prevent DoS
-438 * attacks in the high resolution timer case. This is
-439 * compliant with the old way of self restarting
-440 * itimers, as the SIGALRM is a legacy signal and only
-441 * queued once. Changing the restart behaviour to
-442 * restart the timer in the signal dequeue path is
-443 * reducing the timer noise on heavy loaded !highres
-444 * systems too.
-445 */
-446 if (unlikely(signr == SIGALRM)) {
-...
-489 }
-
-So instead of looking at 446, we should be looking at 431, which is the line
-that executes just before 446. Here we see that what we are looking for is
-&tsk->signal->shared_pending.
-
-Our next task is now to figure out which function that puts items on this
-"shared_pending" list. A crude, but efficient tool, is git grep:
-
- $ git grep -n 'shared_pending' kernel/
- ...
- kernel/signal.c:828: pending = group ? &t->signal->shared_pending : &t->pending;
- kernel/signal.c:1339: pending = group ? &t->signal->shared_pending : &t->pending;
- ...
-
-There were more results, but none of them were related to list operations,
-and these were the only assignments. We inspect the line numbers more closely
-and find that this is indeed where items are being added to the list:
-
-816 static int send_signal(int sig, struct siginfo *info, struct task_struct *t,
-817 int group)
-818 {
-...
-828 pending = group ? &t->signal->shared_pending : &t->pending;
-...
-851 q = __sigqueue_alloc(t, GFP_ATOMIC, (sig < SIGRTMIN &&
-852 (is_si_special(info) ||
-853 info->si_code >= 0)));
-854 if (q) {
-855 list_add_tail(&q->list, &pending->list);
-...
-890 }
-
-and:
-
-1309 int send_sigqueue(struct sigqueue *q, struct task_struct *t, int group)
-1310 {
-....
-1339 pending = group ? &t->signal->shared_pending : &t->pending;
-1340 list_add_tail(&q->list, &pending->list);
-....
-1347 }
-
-In the first case, the list element we are looking for, "q", is being returned
-from the function __sigqueue_alloc(), which looks like an allocation function.
-Let's take a look at it:
-
-187 static struct sigqueue *__sigqueue_alloc(struct task_struct *t, gfp_t flags,
-188 int override_rlimit)
-189 {
-190 struct sigqueue *q = NULL;
-191 struct user_struct *user;
-192
-193 /*
-194 * We won't get problems with the target's UID changing under us
-195 * because changing it requires RCU be used, and if t != current, the
-196 * caller must be holding the RCU readlock (by way of a spinlock) and
-197 * we use RCU protection here
-198 */
-199 user = get_uid(__task_cred(t)->user);
-200 atomic_inc(&user->sigpending);
-201 if (override_rlimit ||
-202 atomic_read(&user->sigpending) <=
-203 t->signal->rlim[RLIMIT_SIGPENDING].rlim_cur)
-204 q = kmem_cache_alloc(sigqueue_cachep, flags);
-205 if (unlikely(q == NULL)) {
-206 atomic_dec(&user->sigpending);
-207 free_uid(user);
-208 } else {
-209 INIT_LIST_HEAD(&q->list);
-210 q->flags = 0;
-211 q->user = user;
-212 }
-213
-214 return q;
-215 }
-
-We see that this function initializes q->list, q->flags, and q->user. It seems
-that now is the time to look at the definition of "struct sigqueue", e.g.:
-
-14 struct sigqueue {
-15 struct list_head list;
-16 int flags;
-17 siginfo_t info;
-18 struct user_struct *user;
-19 };
-
-And, you might remember, it was a memcpy() on &first->info that caused the
-warning, so this makes perfect sense. It also seems reasonable to assume that
-it is the caller of __sigqueue_alloc() that has the responsibility of filling
-out (initializing) this member.
-
-But just which fields of the struct were uninitialized? Let's look at
-kmemcheck's report again:
-
-WARNING: kmemcheck: Caught 32-bit read from uninitialized memory (ffff88003e4a2024)
-80000000000000000000000000000000000000000088ffff0000000000000000
- i i i i u u u u i i i i i i i i u u u u u u u u u u u u u u u u
- ^
-
-These first two lines are the memory dump of the memory object itself, and the
-shadow bytemap, respectively. The memory object itself is in this case
-&first->info. Just beware that the start of this dump is NOT the start of the
-object itself! The position of the caret (^) corresponds with the address of
-the read (ffff88003e4a2024).
-
-The shadow bytemap dump legend is as follows:
-
- i - initialized
- u - uninitialized
- a - unallocated (memory has been allocated by the slab layer, but has not
- yet been handed off to anybody)
- f - freed (memory has been allocated by the slab layer, but has been freed
- by the previous owner)
-
-In order to figure out where (relative to the start of the object) the
-uninitialized memory was located, we have to look at the disassembly. For
-that, we'll need the RIP address again:
-
-RIP: 0010:[<ffffffff8104ede8>] [<ffffffff8104ede8>] __dequeue_signal+0xc8/0x190
-
- $ objdump -d --no-show-raw-insn vmlinux | grep -C 8 ffffffff8104ede8:
- ffffffff8104edc8: mov %r8,0x8(%r8)
- ffffffff8104edcc: test %r10d,%r10d
- ffffffff8104edcf: js ffffffff8104ee88 <__dequeue_signal+0x168>
- ffffffff8104edd5: mov %rax,%rdx
- ffffffff8104edd8: mov $0xc,%ecx
- ffffffff8104eddd: mov %r13,%rdi
- ffffffff8104ede0: mov $0x30,%eax
- ffffffff8104ede5: mov %rdx,%rsi
- ffffffff8104ede8: rep movsl %ds:(%rsi),%es:(%rdi)
- ffffffff8104edea: test $0x2,%al
- ffffffff8104edec: je ffffffff8104edf0 <__dequeue_signal+0xd0>
- ffffffff8104edee: movsw %ds:(%rsi),%es:(%rdi)
- ffffffff8104edf0: test $0x1,%al
- ffffffff8104edf2: je ffffffff8104edf5 <__dequeue_signal+0xd5>
- ffffffff8104edf4: movsb %ds:(%rsi),%es:(%rdi)
- ffffffff8104edf5: mov %r8,%rdi
- ffffffff8104edf8: callq ffffffff8104de60 <__sigqueue_free>
-
-As expected, it's the "rep movsl" instruction from the memcpy() that causes
-the warning. We know about REP MOVSL that it uses the register RCX to count
-the number of remaining iterations. By taking a look at the register dump
-again (from the kmemcheck report), we can figure out how many bytes were left
-to copy:
-
-RAX: 0000000000000030 RBX: ffff88003d4ea968 RCX: 0000000000000009
-
-By looking at the disassembly, we also see that %ecx is being loaded with the
-value $0xc just before (ffffffff8104edd8), so we are very lucky. Keep in mind
-that this is the number of iterations, not bytes. And since this is a "long"
-operation, we need to multiply by 4 to get the number of bytes. So this means
-that the uninitialized value was encountered at 4 * (0xc - 0x9) = 12 bytes
-from the start of the object.
-
-We can now try to figure out which field of the "struct siginfo" that was not
-initialized. This is the beginning of the struct:
-
-40 typedef struct siginfo {
-41 int si_signo;
-42 int si_errno;
-43 int si_code;
-44
-45 union {
-..
-92 } _sifields;
-93 } siginfo_t;
-
-On 64-bit, the int is 4 bytes long, so it must the union member that has
-not been initialized. We can verify this using gdb:
-
- $ gdb vmlinux
- ...
- (gdb) p &((struct siginfo *) 0)->_sifields
- $1 = (union {...} *) 0x10
-
-Actually, it seems that the union member is located at offset 0x10 -- which
-means that gcc has inserted 4 bytes of padding between the members si_code
-and _sifields. We can now get a fuller picture of the memory dump:
-
- _----------------------------=> si_code
- / _--------------------=> (padding)
- | / _------------=> _sifields(._kill._pid)
- | | / _----=> _sifields(._kill._uid)
- | | | /
--------|-------|-------|-------|
-80000000000000000000000000000000000000000088ffff0000000000000000
- i i i i u u u u i i i i i i i i u u u u u u u u u u u u u u u u
-
-This allows us to realize another important fact: si_code contains the value
-0x80. Remember that x86 is little endian, so the first 4 bytes "80000000" are
-really the number 0x00000080. With a bit of research, we find that this is
-actually the constant SI_KERNEL defined in include/asm-generic/siginfo.h:
-
-144 #define SI_KERNEL 0x80 /* sent by the kernel from somewhere */
-
-This macro is used in exactly one place in the x86 kernel: In send_signal()
-in kernel/signal.c:
-
-816 static int send_signal(int sig, struct siginfo *info, struct task_struct *t,
-817 int group)
-818 {
-...
-828 pending = group ? &t->signal->shared_pending : &t->pending;
-...
-851 q = __sigqueue_alloc(t, GFP_ATOMIC, (sig < SIGRTMIN &&
-852 (is_si_special(info) ||
-853 info->si_code >= 0)));
-854 if (q) {
-855 list_add_tail(&q->list, &pending->list);
-856 switch ((unsigned long) info) {
-...
-865 case (unsigned long) SEND_SIG_PRIV:
-866 q->info.si_signo = sig;
-867 q->info.si_errno = 0;
-868 q->info.si_code = SI_KERNEL;
-869 q->info.si_pid = 0;
-870 q->info.si_uid = 0;
-871 break;
-...
-890 }
-
-Not only does this match with the .si_code member, it also matches the place
-we found earlier when looking for where siginfo_t objects are enqueued on the
-"shared_pending" list.
-
-So to sum up: It seems that it is the padding introduced by the compiler
-between two struct fields that is uninitialized, and this gets reported when
-we do a memcpy() on the struct. This means that we have identified a false
-positive warning.
-
-Normally, kmemcheck will not report uninitialized accesses in memcpy() calls
-when both the source and destination addresses are tracked. (Instead, we copy
-the shadow bytemap as well). In this case, the destination address clearly
-was not tracked. We can dig a little deeper into the stack trace from above:
-
- arch/x86/kernel/signal.c:805
- arch/x86/kernel/signal.c:871
- arch/x86/kernel/entry_64.S:694
-
-And we clearly see that the destination siginfo object is located on the
-stack:
-
-782 static void do_signal(struct pt_regs *regs)
-783 {
-784 struct k_sigaction ka;
-785 siginfo_t info;
-...
-804 signr = get_signal_to_deliver(&info, &ka, regs, NULL);
-...
-854 }
-
-And this &info is what eventually gets passed to copy_siginfo() as the
-destination argument.
-
-Now, even though we didn't find an actual error here, the example is still a
-good one, because it shows how one would go about to find out what the report
-was all about.
-
-
-3.4. Annotating false positives
-===============================
-
-There are a few different ways to make annotations in the source code that
-will keep kmemcheck from checking and reporting certain allocations. Here
-they are:
-
- o __GFP_NOTRACK_FALSE_POSITIVE
-
- This flag can be passed to kmalloc() or kmem_cache_alloc() (therefore
- also to other functions that end up calling one of these) to indicate
- that the allocation should not be tracked because it would lead to
- a false positive report. This is a "big hammer" way of silencing
- kmemcheck; after all, even if the false positive pertains to
- particular field in a struct, for example, we will now lose the
- ability to find (real) errors in other parts of the same struct.
-
- Example:
-
- /* No warnings will ever trigger on accessing any part of x */
- x = kmalloc(sizeof *x, GFP_KERNEL | __GFP_NOTRACK_FALSE_POSITIVE);
-
- o kmemcheck_bitfield_begin(name)/kmemcheck_bitfield_end(name) and
- kmemcheck_annotate_bitfield(ptr, name)
-
- The first two of these three macros can be used inside struct
- definitions to signal, respectively, the beginning and end of a
- bitfield. Additionally, this will assign the bitfield a name, which
- is given as an argument to the macros.
-
- Having used these markers, one can later use
- kmemcheck_annotate_bitfield() at the point of allocation, to indicate
- which parts of the allocation is part of a bitfield.
-
- Example:
-
- struct foo {
- int x;
-
- kmemcheck_bitfield_begin(flags);
- int flag_a:1;
- int flag_b:1;
- kmemcheck_bitfield_end(flags);
-
- int y;
- };
-
- struct foo *x = kmalloc(sizeof *x);
-
- /* No warnings will trigger on accessing the bitfield of x */
- kmemcheck_annotate_bitfield(x, flags);
-
- Note that kmemcheck_annotate_bitfield() can be used even before the
- return value of kmalloc() is checked -- in other words, passing NULL
- as the first argument is legal (and will do nothing).
-
-
-4. Reporting errors
-===================
-
-As we have seen, kmemcheck will produce false positive reports. Therefore, it
-is not very wise to blindly post kmemcheck warnings to mailing lists and
-maintainers. Instead, I encourage maintainers and developers to find errors
-in their own code. If you get a warning, you can try to work around it, try
-to figure out if it's a real error or not, or simply ignore it. Most
-developers know their own code and will quickly and efficiently determine the
-root cause of a kmemcheck report. This is therefore also the most efficient
-way to work with kmemcheck.
-
-That said, we (the kmemcheck maintainers) will always be on the lookout for
-false positives that we can annotate and silence. So whatever you find,
-please drop us a note privately! Kernel configs and steps to reproduce (if
-available) are of course a great help too.
-
-Happy hacking!
-
-
-5. Technical description
-========================
-
-kmemcheck works by marking memory pages non-present. This means that whenever
-somebody attempts to access the page, a page fault is generated. The page
-fault handler notices that the page was in fact only hidden, and so it calls
-on the kmemcheck code to make further investigations.
-
-When the investigations are completed, kmemcheck "shows" the page by marking
-it present (as it would be under normal circumstances). This way, the
-interrupted code can continue as usual.
-
-But after the instruction has been executed, we should hide the page again, so
-that we can catch the next access too! Now kmemcheck makes use of a debugging
-feature of the processor, namely single-stepping. When the processor has
-finished the one instruction that generated the memory access, a debug
-exception is raised. From here, we simply hide the page again and continue
-execution, this time with the single-stepping feature turned off.
-
-kmemcheck requires some assistance from the memory allocator in order to work.
-The memory allocator needs to
-
- 1. Tell kmemcheck about newly allocated pages and pages that are about to
- be freed. This allows kmemcheck to set up and tear down the shadow memory
- for the pages in question. The shadow memory stores the status of each
- byte in the allocation proper, e.g. whether it is initialized or
- uninitialized.
-
- 2. Tell kmemcheck which parts of memory should be marked uninitialized.
- There are actually a few more states, such as "not yet allocated" and
- "recently freed".
-
-If a slab cache is set up using the SLAB_NOTRACK flag, it will never return
-memory that can take page faults because of kmemcheck.
-
-If a slab cache is NOT set up using the SLAB_NOTRACK flag, callers can still
-request memory with the __GFP_NOTRACK or __GFP_NOTRACK_FALSE_POSITIVE flags.
-This does not prevent the page faults from occurring, however, but marks the
-object in question as being initialized so that no warnings will ever be
-produced for this object.
-
-Currently, the SLAB and SLUB allocators are supported by kmemcheck.

-Kernel Memory Leak Detector
-===========================
-
-Introduction
-------------
-
-Kmemleak provides a way of detecting possible kernel memory leaks in a
-way similar to a tracing garbage collector
-(https://en.wikipedia.org/wiki/Garbage_collection_%28computer_science%29#Tracing_garbage_collectors),
-with the difference that the orphan objects are not freed but only
-reported via /sys/kernel/debug/kmemleak. A similar method is used by the
-Valgrind tool (memcheck --leak-check) to detect the memory leaks in
-user-space applications.
-Kmemleak is supported on x86, arm, powerpc, sparc, sh, microblaze, ppc, mips, s390, metag and tile.
-
-Usage
------
-
-CONFIG_DEBUG_KMEMLEAK in "Kernel hacking" has to be enabled. A kernel
-thread scans the memory every 10 minutes (by default) and prints the
-number of new unreferenced objects found. To display the details of all
-the possible memory leaks:
-
- # mount -t debugfs nodev /sys/kernel/debug/
- # cat /sys/kernel/debug/kmemleak
-
-To trigger an intermediate memory scan:
-
- # echo scan > /sys/kernel/debug/kmemleak
-
-To clear the list of all current possible memory leaks:
-
- # echo clear > /sys/kernel/debug/kmemleak
-
-New leaks will then come up upon reading /sys/kernel/debug/kmemleak
-again.
-
-Note that the orphan objects are listed in the order they were allocated
-and one object at the beginning of the list may cause other subsequent
-objects to be reported as orphan.
-
-Memory scanning parameters can be modified at run-time by writing to the
-/sys/kernel/debug/kmemleak file. The following parameters are supported:
-
- off - disable kmemleak (irreversible)
- stack=on - enable the task stacks scanning (default)
- stack=off - disable the tasks stacks scanning
- scan=on - start the automatic memory scanning thread (default)
- scan=off - stop the automatic memory scanning thread
- scan=<secs> - set the automatic memory scanning period in seconds
- (default 600, 0 to stop the automatic scanning)
- scan - trigger a memory scan
- clear - clear list of current memory leak suspects, done by
- marking all current reported unreferenced objects grey,
- or free all kmemleak objects if kmemleak has been disabled.
- dump=<addr> - dump information about the object found at <addr>
-
-Kmemleak can also be disabled at boot-time by passing "kmemleak=off" on
-the kernel command line.
-
-Memory may be allocated or freed before kmemleak is initialised and
-these actions are stored in an early log buffer. The size of this buffer
-is configured via the CONFIG_DEBUG_KMEMLEAK_EARLY_LOG_SIZE option.
-
-If CONFIG_DEBUG_KMEMLEAK_DEFAULT_OFF are enabled, the kmemleak is
-disabled by default. Passing "kmemleak=on" on the kernel command
-line enables the function.
-
-Basic Algorithm
----------------
-
-The memory allocations via kmalloc, vmalloc, kmem_cache_alloc and
-friends are traced and the pointers, together with additional
-information like size and stack trace, are stored in a rbtree.
-The corresponding freeing function calls are tracked and the pointers
-removed from the kmemleak data structures.
-
-An allocated block of memory is considered orphan if no pointer to its
-start address or to any location inside the block can be found by
-scanning the memory (including saved registers). This means that there
-might be no way for the kernel to pass the address of the allocated
-block to a freeing function and therefore the block is considered a
-memory leak.
-
-The scanning algorithm steps:
-
- 1. mark all objects as white (remaining white objects will later be
- considered orphan)
- 2. scan the memory starting with the data section and stacks, checking
- the values against the addresses stored in the rbtree. If
- a pointer to a white object is found, the object is added to the
- gray list
- 3. scan the gray objects for matching addresses (some white objects
- can become gray and added at the end of the gray list) until the
- gray set is finished
- 4. the remaining white objects are considered orphan and reported via
- /sys/kernel/debug/kmemleak
-
-Some allocated memory blocks have pointers stored in the kernel's
-internal data structures and they cannot be detected as orphans. To
-avoid this, kmemleak can also store the number of values pointing to an
-address inside the block address range that need to be found so that the
-block is not considered a leak. One example is __vmalloc().
-
-Testing specific sections with kmemleak
----------------------------------------
-
-Upon initial bootup your /sys/kernel/debug/kmemleak output page may be
-quite extensive. This can also be the case if you have very buggy code
-when doing development. To work around these situations you can use the
-'clear' command to clear all reported unreferenced objects from the
-/sys/kernel/debug/kmemleak output. By issuing a 'scan' after a 'clear'
-you can find new unreferenced objects; this should help with testing
-specific sections of code.
-
-To test a critical section on demand with a clean kmemleak do:
-
- # echo clear > /sys/kernel/debug/kmemleak
- ... test your kernel or modules ...
- # echo scan > /sys/kernel/debug/kmemleak
-
-Then as usual to get your report with:
-
- # cat /sys/kernel/debug/kmemleak
-
-Freeing kmemleak internal objects
----------------------------------
-
-To allow access to previously found memory leaks after kmemleak has been
-disabled by the user or due to an fatal error, internal kmemleak objects
-won't be freed when kmemleak is disabled, and those objects may occupy
-a large part of physical memory.
-
-In this situation, you may reclaim memory with:
-
- # echo clear > /sys/kernel/debug/kmemleak
-
-Kmemleak API
-------------
-
-See the include/linux/kmemleak.h header for the functions prototype.
-
-kmemleak_init - initialize kmemleak
-kmemleak_alloc - notify of a memory block allocation
-kmemleak_alloc_percpu - notify of a percpu memory block allocation
-kmemleak_free - notify of a memory block freeing
-kmemleak_free_part - notify of a partial memory block freeing
-kmemleak_free_percpu - notify of a percpu memory block freeing
-kmemleak_update_trace - update object allocation stack trace
-kmemleak_not_leak - mark an object as not a leak
-kmemleak_ignore - do not scan or report an object as leak
-kmemleak_scan_area - add scan areas inside a memory block
-kmemleak_no_scan - do not scan a memory block
-kmemleak_erase - erase an old value in a pointer variable
-kmemleak_alloc_recursive - as kmemleak_alloc but checks the recursiveness
-kmemleak_free_recursive - as kmemleak_free but checks the recursiveness
-
-Dealing with false positives/negatives
---------------------------------------
-
-The false negatives are real memory leaks (orphan objects) but not
-reported by kmemleak because values found during the memory scanning
-point to such objects. To reduce the number of false negatives, kmemleak
-provides the kmemleak_ignore, kmemleak_scan_area, kmemleak_no_scan and
-kmemleak_erase functions (see above). The task stacks also increase the
-amount of false negatives and their scanning is not enabled by default.
-
-The false positives are objects wrongly reported as being memory leaks
-(orphan). For objects known not to be leaks, kmemleak provides the
-kmemleak_not_leak function. The kmemleak_ignore could also be used if
-the memory block is known not to contain other pointers and it will no
-longer be scanned.
-
-Some of the reported leaks are only transient, especially on SMP
-systems, because of pointers temporarily stored in CPU registers or
-stacks. Kmemleak defines MSECS_MIN_AGE (defaulting to 1000) representing
-the minimum age of an object to be reported as a memory leak.
-
-Limitations and Drawbacks
--------------------------
-
-The main drawback is the reduced performance of memory allocation and
-freeing. To avoid other penalties, the memory scanning is only performed
-when the /sys/kernel/debug/kmemleak file is read. Anyway, this tool is
-intended for debugging purposes where the performance might not be the
-most important requirement.
-
-To keep the algorithm simple, kmemleak scans for values pointing to any
-address inside a block's address range. This may lead to an increased
-number of false negatives. However, it is likely that a real memory leak
-will eventually become visible.
-
-Another source of false negatives is the data stored in non-pointer
-values. In a future version, kmemleak could only scan the pointer
-members in the allocated structures. This feature would solve many of
-the false negative cases described above.
-
-The tool can report false positives. These are cases where an allocated
-block doesn't need to be freed (some cases in the init_call functions),
-the pointer is calculated by other methods than the usual container_of
-macro or the pointer is stored in a location not scanned by kmemleak.
-
-Page allocations and ioremap are not tracked.

+=======================
+추상 메모리 액세스 모델
+=======================
+
+다음과 같이 추상화된 시스템 모델을 생각해 봅시다:
+
+ : :
+ : :
+ : :
+ +-------+ : +--------+ : +-------+
+ | | : | | : | |
+ | | : | | : | |
+ | CPU 1 |<----->| Memory |<----->| CPU 2 |

+
+프로그램은 여러 메모리 액세스 오퍼레이션을 발생시키고, 각각의 CPU 는 그런
+프로그램들을 실행합니다. 추상화된 CPU 모델에서 메모리 오퍼레이션들의 순서는
+매우 완화되어 있고, CPU 는 프로그램이 인과관계를 어기지 않는 상태로 관리된다고
+보일 수만 있다면 메모리 오퍼레이션을 자신이 원하는 어떤 순서대로든 재배치해
+동작시킬 수 있습니다. 비슷하게, 컴파일러 또한 프로그램의 정상적 동작을 해치지
+않는 한도 내에서는 어떤 순서로든 자신이 원하는 대로 인스트럭션을 재배치 할 수
+있습니다.
+
+따라서 위의 다이어그램에서 한 CPU가 동작시키는 메모리 오퍼레이션이 만들어내는
+변화는 해당 오퍼레이션이 CPU 와 시스템의 다른 부분들 사이의 인터페이스(점선)를
+지나가면서 시스템의 나머지 부분들에 인지됩니다.
+
+
+예를 들어, 다음의 일련의 이벤트들을 생각해 봅시다:
+
+ CPU 1 CPU 2
+ =============== ===============
+ { A == 1; B == 2 }
+ A = 3; x = B;
+ B = 4; y = A;
+
+다이어그램의 가운데에 위치한 메모리 시스템에 보여지게 되는 액세스들은 다음의 총
+24개의 조합으로 재구성될 수 있습니다:
+
+ STORE A=3, STORE B=4, y=LOAD A->3, x=LOAD B->4
+ STORE A=3, STORE B=4, x=LOAD B->4, y=LOAD A->3
+ STORE A=3, y=LOAD A->3, STORE B=4, x=LOAD B->4
+ STORE A=3, y=LOAD A->3, x=LOAD B->2, STORE B=4
+ STORE A=3, x=LOAD B->2, STORE B=4, y=LOAD A->3
+ STORE A=3, x=LOAD B->2, y=LOAD A->3, STORE B=4
+ STORE B=4, STORE A=3, y=LOAD A->3, x=LOAD B->4
+ STORE B=4, ...
+ ...
+
+따라서 다음의 네가지 조합의 값들이 나올 수 있습니다:
+
+ x == 2, y == 1
+ x == 2, y == 3
+ x == 4, y == 1
+ x == 4, y == 3
+
+
+한발 더 나아가서, 한 CPU 가 메모리 시스템에 반영한 스토어 오퍼레이션들의 결과는
+다른 CPU 에서의 로드 오퍼레이션을 통해 인지되는데, 이 때 스토어가 반영된 순서와
+다른 순서로 인지될 수도 있습니다.
+
+
+예로, 아래의 일련의 이벤트들을 생각해 봅시다:
+
+ CPU 1 CPU 2
+ =============== ===============
+ { A == 1, B == 2, C == 3, P == &A, Q == &C }
+ B = 4; Q = P;
+ P = &B D = *Q;
+
+D 로 읽혀지는 값은 CPU 2 에서 P 로부터 읽혀진 주소값에 의존적이기 때문에 여기엔
+분명한 데이터 의존성이 있습니다. 하지만 이 이벤트들의 실행 결과로는 아래의
+결과들이 모두 나타날 수 있습니다:
+
+ (Q == &A) and (D == 1)
+ (Q == &B) and (D == 2)
+ (Q == &B) and (D == 4)
+
+CPU 2 는 *Q 의 로드를 요청하기 전에 P 를 Q 에 넣기 때문에 D 에 C 를 집어넣는
+일은 없음을 알아두세요.
+
+
+디바이스 오퍼레이션
+-------------------
+
+일부 디바이스는 자신의 컨트롤 인터페이스를 메모리의 특정 영역으로 매핑해서
+제공하는데(Memory mapped I/O), 해당 컨트롤 레지스터에 접근하는 순서는 매우
+중요합니다. 예를 들어, 어드레스 포트 레지스터 (A) 와 데이터 포트 레지스터 (D)
+를 통해 접근되는 내부 레지스터 집합을 갖는 이더넷 카드를 생각해 봅시다. 내부의
+5번 레지스터를 읽기 위해 다음의 코드가 사용될 수 있습니다:
+
+ *A = 5;
+ x = *D;
+
+하지만, 이건 다음의 두 조합 중 하나로 만들어질 수 있습니다:
+
+ STORE *A = 5, x = LOAD *D
+ x = LOAD *D, STORE *A = 5
+
+두번째 조합은 데이터를 읽어온 _후에_ 주소를 설정하므로, 오동작을 일으킬 겁니다.
+
+
+보장사항
+--------
+
+CPU 에게 기대할 수 있는 최소한의 보장사항 몇가지가 있습니다:
+
+ (*) 어떤 CPU 든, 의존성이 존재하는 메모리 액세스들은 해당 CPU 자신에게
+ 있어서는 순서대로 메모리 시스템에 수행 요청됩니다. 즉, 다음에 대해서:
+
+ Q = READ_ONCE(P); smp_read_barrier_depends(); D = READ_ONCE(*Q);
+
+ CPU 는 다음과 같은 메모리 오퍼레이션 시퀀스를 수행 요청합니다:
+
+ Q = LOAD P, D = LOAD *Q
+
+ 그리고 그 시퀀스 내에서의 순서는 항상 지켜집니다. 대부분의 시스템에서
+ smp_read_barrier_depends() 는 아무일도 안하지만 DEC Alpha 에서는
+ 명시적으로 사용되어야 합니다. 보통의 경우에는 smp_read_barrier_depends()
+ 를 직접 사용하는 대신 rcu_dereference() 같은 것들을 사용해야 함을
+ 알아두세요.
+
+ (*) 특정 CPU 내에서 겹치는 영역의 메모리에 행해지는 로드와 스토어 들은 해당
+ CPU 안에서는 순서가 바뀌지 않은 것으로 보여집니다. 즉, 다음에 대해서:
+
+ a = READ_ONCE(*X); WRITE_ONCE(*X, b);
+
+ CPU 는 다음의 메모리 오퍼레이션 시퀀스만을 메모리에 요청할 겁니다:
+
+ a = LOAD *X, STORE *X = b
+
+ 그리고 다음에 대해서는:
+
+ WRITE_ONCE(*X, c); d = READ_ONCE(*X);
+
+ CPU 는 다음의 수행 요청만을 만들어 냅니다:
+
+ STORE *X = c, d = LOAD *X
+
+ (로드 오퍼레이션과 스토어 오퍼레이션이 겹치는 메모리 영역에 대해
+ 수행된다면 해당 오퍼레이션들은 겹친다고 표현됩니다).
+
+그리고 _반드시_ 또는 _절대로_ 가정하거나 가정하지 말아야 하는 것들이 있습니다:
+
+ (*) 컴파일러가 READ_ONCE() 나 WRITE_ONCE() 로 보호되지 않은 메모리 액세스를
+ 당신이 원하는 대로 할 것이라는 가정은 _절대로_ 해선 안됩니다. 그것들이
+ 없다면, 컴파일러는 컴파일러 배리어 섹션에서 다루게 될, 모든 "창의적인"
+ 변경들을 만들어낼 권한을 갖게 됩니다.
+
+ (*) 개별적인 로드와 스토어들이 주어진 순서대로 요청될 것이라는 가정은 _절대로_
+ 하지 말아야 합니다. 이 말은 곧:
+
+ X = *A; Y = *B; *D = Z;
+
+ 는 다음의 것들 중 어느 것으로든 만들어질 수 있다는 의미입니다:
+
+ X = LOAD *A, Y = LOAD *B, STORE *D = Z
+ X = LOAD *A, STORE *D = Z, Y = LOAD *B
+ Y = LOAD *B, X = LOAD *A, STORE *D = Z
+ Y = LOAD *B, STORE *D = Z, X = LOAD *A
+ STORE *D = Z, X = LOAD *A, Y = LOAD *B
+ STORE *D = Z, Y = LOAD *B, X = LOAD *A
+
+ (*) 겹치는 메모리 액세스들은 합쳐지거나 버려질 수 있음을 _반드시_ 가정해야
+ 합니다. 다음의 코드는:
+
+ X = *A; Y = *(A + 4);
+
+ 다음의 것들 중 뭐든 될 수 있습니다:
+
+ X = LOAD *A; Y = LOAD *(A + 4);
+ Y = LOAD *(A + 4); X = LOAD *A;
+ {X, Y} = LOAD {*A, *(A + 4) };
+
+ 그리고:
+
+ *A = X; *(A + 4) = Y;
+
+ 는 다음 중 뭐든 될 수 있습니다:
+
+ STORE *A = X; STORE *(A + 4) = Y;
+ STORE *(A + 4) = Y; STORE *A = X;
+ STORE {*A, *(A + 4) } = {X, Y};
+
+그리고 보장사항에 반대되는 것들(anti-guarantees)이 있습니다:
+
+ (*) 이 보장사항들은 bitfield 에는 적용되지 않는데, 컴파일러들은 bitfield 를
+ 수정하는 코드를 생성할 때 원자성 없는(non-atomic) 읽고-수정하고-쓰는
+ 인스트럭션들의 조합을 만드는 경우가 많기 때문입니다. 병렬 알고리즘의
+ 동기화에 bitfield 를 사용하려 하지 마십시오.
+
+ (*) bitfield 들이 여러 락으로 보호되는 경우라 하더라도, 하나의 bitfield 의
+ 모든 필드들은 하나의 락으로 보호되어야 합니다. 만약 한 bitfield 의 두
+ 필드가 서로 다른 락으로 보호된다면, 컴파일러의 원자성 없는
+ 읽고-수정하고-쓰는 인스트럭션 조합은 한 필드에의 업데이트가 근처의
+ 필드에도 영향을 끼치게 할 수 있습니다.
+
+ (*) 이 보장사항들은 적절하게 정렬되고 크기가 잡힌 스칼라 변수들에 대해서만
+ 적용됩니다. "적절하게 크기가 잡힌" 이라함은 현재로써는 "char", "short",
+ "int" 그리고 "long" 과 같은 크기의 변수들을 의미합니다. "적절하게 정렬된"
+ 은 자연스런 정렬을 의미하는데, 따라서 "char" 에 대해서는 아무 제약이 없고,
+ "short" 에 대해서는 2바이트 정렬을, "int" 에는 4바이트 정렬을, 그리고
+ "long" 에 대해서는 32-bit 시스템인지 64-bit 시스템인지에 따라 4바이트 또는
+ 8바이트 정렬을 의미합니다. 이 보장사항들은 C11 표준에서 소개되었으므로,
+ C11 전의 오래된 컴파일러(예를 들어, gcc 4.6) 를 사용할 때엔 주의하시기
+ 바랍니다. 표준에 이 보장사항들은 "memory location" 을 정의하는 3.14
+ 섹션에 다음과 같이 설명되어 있습니다:
+ (역자: 인용문이므로 번역하지 않습니다)
+
+ memory location
+ either an object of scalar type, or a maximal sequence
+ of adjacent bit-fields all having nonzero width
+
+ NOTE 1: Two threads of execution can update and access
+ separate memory locations without interfering with
+ each other.
+
+ NOTE 2: A bit-field and an adjacent non-bit-field member
+ are in separate memory locations. The same applies
+ to two bit-fields, if one is declared inside a nested
+ structure declaration and the other is not, or if the two
+ are separated by a zero-length bit-field declaration,
+ or if they are separated by a non-bit-field member
+ declaration. It is not safe to concurrently update two
+ bit-fields in the same structure if all members declared
+ between them are also bit-fields, no matter what the
+ sizes of those intervening bit-fields happen to be.
+
+
+=========================
+메모리 배리어란 무엇인가?
+=========================
+
+앞에서 봤듯이, 상호간 의존성이 없는 메모리 오퍼레이션들은 실제로는 무작위적
+순서로 수행될 수 있으며, 이는 CPU 와 CPU 간의 상호작용이나 I/O 에 문제가 될 수
+있습니다. 따라서 컴파일러와 CPU 가 순서를 바꾸는데 제약을 걸 수 있도록 개입할
+수 있는 어떤 방법이 필요합니다.
+
+메모리 배리어는 그런 개입 수단입니다. 메모리 배리어는 배리어를 사이에 둔 앞과
+뒤 양측의 메모리 오퍼레이션들 간에 부분적 순서가 존재하도록 하는 효과를 줍니다.
+
+시스템의 CPU 들과 여러 디바이스들은 성능을 올리기 위해 명령어 재배치, 실행
+유예, 메모리 오퍼레이션들의 조합, 예측적 로드(speculative load), 브랜치
+예측(speculative branch prediction), 다양한 종류의 캐싱(caching) 등의 다양한
+트릭을 사용할 수 있기 때문에 이런 강제력은 중요합니다. 메모리 배리어들은 이런
+트릭들을 무효로 하거나 억제하는 목적으로 사용되어져서 코드가 여러 CPU 와
+디바이스들 간의 상호작용을 정상적으로 제어할 수 있게 해줍니다.
+
+
+메모리 배리어의 종류
+--------------------
+
+메모리 배리어는 네개의 기본 타입으로 분류됩니다:
+
+ (1) 쓰기 (또는 스토어) 메모리 배리어.
+
+ 쓰기 메모리 배리어는 시스템의 다른 컴포넌트들에 해당 배리어보다 앞서
+ 명시된 모든 STORE 오퍼레이션들이 해당 배리어 뒤에 명시된 모든 STORE
+ 오퍼레이션들보다 먼저 수행된 것으로 보일 것을 보장합니다.
+
+ 쓰기 배리어는 스토어 오퍼레이션들에 대한 부분적 순서 세우기입니다; 로드
+ 오퍼레이션들에 대해서는 어떤 영향도 끼치지 않습니다.
+
+ CPU 는 시간의 흐름에 따라 메모리 시스템에 일련의 스토어 오퍼레이션들을
+ 하나씩 요청해 집어넣습니다. 쓰기 배리어 앞의 모든 스토어 오퍼레이션들은
+ 쓰기 배리어 뒤의 모든 스토어 오퍼레이션들보다 _앞서_ 수행될 겁니다.
+
+ [!] 쓰기 배리어들은 읽기 또는 데이터 의존성 배리어와 함께 짝을 맞춰
+ 사용되어야만 함을 알아두세요; "SMP 배리어 짝맞추기" 서브섹션을 참고하세요.
+
+
+ (2) 데이터 의존성 배리어.
+
+ 데이터 의존성 배리어는 읽기 배리어의 보다 완화된 형태입니다. 두개의 로드
+ 오퍼레이션이 있고 두번째 것이 첫번째 것의 결과에 의존하고 있을 때(예:
+ 두번째 로드가 참조할 주소를 첫번째 로드가 읽는 경우), 두번째 로드가 읽어올
+ 데이터는 첫번째 로드에 의해 그 주소가 얻어지기 전에 업데이트 되어 있음을
+ 보장하기 위해서 데이터 의존성 배리어가 필요할 수 있습니다.
+
+ 데이터 의존성 배리어는 상호 의존적인 로드 오퍼레이션들 사이의 부분적 순서
+ 세우기입니다; 스토어 오퍼레이션들이나 독립적인 로드들, 또는 중복되는
+ 로드들에 대해서는 어떤 영향도 끼치지 않습니다.
+
+ (1) 에서 언급했듯이, 시스템의 CPU 들은 메모리 시스템에 일련의 스토어
+ 오퍼레이션들을 던져 넣고 있으며, 거기에 관심이 있는 다른 CPU 는 그
+ 오퍼레이션들을 메모리 시스템이 실행한 결과를 인지할 수 있습니다. 이처럼
+ 다른 CPU 의 스토어 오퍼레이션의 결과에 관심을 두고 있는 CPU 가 수행 요청한
+ 데이터 의존성 배리어는, 배리어 앞의 어떤 로드 오퍼레이션이 다른 CPU 에서
+ 던져 넣은 스토어 오퍼레이션과 같은 영역을 향했다면, 그런 스토어
+ 오퍼레이션들이 만들어내는 결과가 데이터 의존성 배리어 뒤의 로드
+ 오퍼레이션들에게는 보일 것을 보장합니다.
+
+ 이 순서 세우기 제약에 대한 그림을 보기 위해선 "메모리 배리어 시퀀스의 예"
+ 서브섹션을 참고하시기 바랍니다.
+
+ [!] 첫번째 로드는 반드시 _데이터_ 의존성을 가져야지 컨트롤 의존성을 가져야
+ 하는게 아님을 알아두십시오. 만약 두번째 로드를 위한 주소가 첫번째 로드에
+ 의존적이지만 그 의존성은 조건적이지 그 주소 자체를 가져오는게 아니라면,
+ 그것은 _컨트롤_ 의존성이고, 이 경우에는 읽기 배리어나 그보다 강력한
+ 무언가가 필요합니다. 더 자세한 내용을 위해서는 "컨트롤 의존성" 서브섹션을
+ 참고하시기 바랍니다.
+
+ [!] 데이터 의존성 배리어는 보통 쓰기 배리어들과 함께 짝을 맞춰 사용되어야
+ 합니다; "SMP 배리어 짝맞추기" 서브섹션을 참고하세요.
+
+
+ (3) 읽기 (또는 로드) 메모리 배리어.
+
+ 읽기 배리어는 데이터 의존성 배리어 기능의 보장사항에 더해서 배리어보다
+ 앞서 명시된 모든 LOAD 오퍼레이션들이 배리어 뒤에 명시되는 모든 LOAD
+ 오퍼레이션들보다 먼저 행해진 것으로 시스템의 다른 컴포넌트들에 보여질 것을
+ 보장합니다.
+
+ 읽기 배리어는 로드 오퍼레이션에 행해지는 부분적 순서 세우기입니다; 스토어
+ 오퍼레이션에 대해서는 어떤 영향도 끼치지 않습니다.
+
+ 읽기 메모리 배리어는 데이터 의존성 배리어를 내장하므로 데이터 의존성
+ 배리어를 대신할 수 있습니다.
+
+ [!] 읽기 배리어는 일반적으로 쓰기 배리어들과 함께 짝을 맞춰 사용되어야
+ 합니다; "SMP 배리어 짝맞추기" 서브섹션을 참고하세요.
+
+
+ (4) 범용 메모리 배리어.
+
+ 범용(general) 메모리 배리어는 배리어보다 앞서 명시된 모든 LOAD 와 STORE
+ 오퍼레이션들이 배리어 뒤에 명시된 모든 LOAD 와 STORE 오퍼레이션들보다
+ 먼저 수행된 것으로 시스템의 나머지 컴포넌트들에 보이게 됨을 보장합니다.
+
+ 범용 메모리 배리어는 로드와 스토어 모두에 대한 부분적 순서 세우기입니다.
+
+ 범용 메모리 배리어는 읽기 메모리 배리어, 쓰기 메모리 배리어 모두를
+ 내장하므로, 두 배리어를 모두 대신할 수 있습니다.
+
+
+그리고 두개의 명시적이지 않은 타입이 있습니다:
+
+ (5) ACQUIRE 오퍼레이션.
+
+ 이 타입의 오퍼레이션은 단방향의 투과성 배리어처럼 동작합니다. ACQUIRE
+ 오퍼레이션 뒤의 모든 메모리 오퍼레이션들이 ACQUIRE 오퍼레이션 후에
+ 일어난 것으로 시스템의 나머지 컴포넌트들에 보이게 될 것이 보장됩니다.
+ LOCK 오퍼레이션과 smp_load_acquire(), smp_cond_acquire() 오퍼레이션도
+ ACQUIRE 오퍼레이션에 포함됩니다. smp_cond_acquire() 오퍼레이션은 컨트롤
+ 의존성과 smp_rmb() 를 사용해서 ACQUIRE 의 의미적 요구사항(semantic)을
+ 충족시킵니다.
+
+ ACQUIRE 오퍼레이션 앞의 메모리 오퍼레이션들은 ACQUIRE 오퍼레이션 완료 후에
+ 수행된 것처럼 보일 수 있습니다.
+
+ ACQUIRE 오퍼레이션은 거의 항상 RELEASE 오퍼레이션과 짝을 지어 사용되어야
+ 합니다.
+
+
+ (6) RELEASE 오퍼레이션.
+
+ 이 타입의 오퍼레이션들도 단방향 투과성 배리어처럼 동작합니다. RELEASE
+ 오퍼레이션 앞의 모든 메모리 오퍼레이션들은 RELEASE 오퍼레이션 전에 완료된
+ 것으로 시스템의 다른 컴포넌트들에 보여질 것이 보장됩니다. UNLOCK 류의
+ 오퍼레이션들과 smp_store_release() 오퍼레이션도 RELEASE 오퍼레이션의
+ 일종입니다.
+
+ RELEASE 오퍼레이션 뒤의 메모리 오퍼레이션들은 RELEASE 오퍼레이션이
+ 완료되기 전에 행해진 것처럼 보일 수 있습니다.
+
+ ACQUIRE 와 RELEASE 오퍼레이션의 사용은 일반적으로 다른 메모리 배리어의
+ 필요성을 없앱니다 (하지만 "MMIO 쓰기 배리어" 서브섹션에서 설명되는 예외를
+ 알아두세요). 또한, RELEASE+ACQUIRE 조합은 범용 메모리 배리어처럼 동작할
+ 것을 보장하지 -않습니다-. 하지만, 어떤 변수에 대한 RELEASE 오퍼레이션을
+ 앞서는 메모리 액세스들의 수행 결과는 이 RELEASE 오퍼레이션을 뒤이어 같은
+ 변수에 대해 수행된 ACQUIRE 오퍼레이션을 뒤따르는 메모리 액세스에는 보여질
+ 것이 보장됩니다. 다르게 말하자면, 주어진 변수의 크리티컬 섹션에서는, 해당
+ 변수에 대한 앞의 크리티컬 섹션에서의 모든 액세스들이 완료되었을 것을
+ 보장합니다.
+
+ 즉, ACQUIRE 는 최소한의 "취득" 동작처럼, 그리고 RELEASE 는 최소한의 "공개"
+ 처럼 동작한다는 의미입니다.
+
+atomic_ops.txt 에서 설명되는 어토믹 오퍼레이션들 중에는 완전히 순서잡힌 것들과
+(배리어를 사용하지 않는) 완화된 순서의 것들 외에 ACQUIRE 와 RELEASE 부류의
+것들도 존재합니다. 로드와 스토어를 모두 수행하는 조합된 어토믹 오퍼레이션에서,
+ACQUIRE 는 해당 오퍼레이션의 로드 부분에만 적용되고 RELEASE 는 해당
+오퍼레이션의 스토어 부분에만 적용됩니다.
+
+메모리 배리어들은 두 CPU 간, 또는 CPU 와 디바이스 간에 상호작용의 가능성이 있을
+때에만 필요합니다. 만약 어떤 코드에 그런 상호작용이 없을 것이 보장된다면, 해당
+코드에서는 메모리 배리어를 사용할 필요가 없습니다.
+
+
+이것들은 _최소한의_ 보장사항들임을 알아두세요. 다른 아키텍쳐에서는 더 강력한
+보장사항을 제공할 수도 있습니다만, 그런 보장사항은 아키텍쳐 종속적 코드 이외의
+부분에서는 신뢰되지 _않을_ 겁니다.
+
+
+메모리 배리어에 대해 가정해선 안될 것
+-------------------------------------
+
+리눅스 커널 메모리 배리어들이 보장하지 않는 것들이 있습니다:
+
+ (*) 메모리 배리어 앞에서 명시된 어떤 메모리 액세스도 메모리 배리어 명령의 수행
+ 완료 시점까지 _완료_ 될 것이란 보장은 없습니다; 배리어가 하는 일은 CPU 의
+ 액세스 큐에 특정 타입의 액세스들은 넘을 수 없는 선을 긋는 것으로 생각될 수
+ 있습니다.
+
+ (*) 한 CPU 에서 메모리 배리어를 수행하는게 시스템의 다른 CPU 나 하드웨어에
+ 어떤 직접적인 영향을 끼친다는 보장은 존재하지 않습니다. 배리어 수행이
+ 만드는 간접적 영향은 두번째 CPU 가 첫번째 CPU 의 액세스들의 결과를
+ 바라보는 순서가 됩니다만, 다음 항목을 보세요:
+
+ (*) 첫번째 CPU 가 두번째 CPU 의 메모리 액세스들의 결과를 바라볼 때, _설령_
+ 두번째 CPU 가 메모리 배리어를 사용한다 해도, 첫번째 CPU _또한_ 그에 맞는
+ 메모리 배리어를 사용하지 않는다면 ("SMP 배리어 짝맞추기" 서브섹션을
+ 참고하세요) 그 결과가 올바른 순서로 보여진다는 보장은 없습니다.
+
+ (*) CPU 바깥의 하드웨어[*] 가 메모리 액세스들의 순서를 바꾸지 않는다는 보장은
+ 존재하지 않습니다. CPU 캐시 일관성 메커니즘은 메모리 배리어의 간접적
+ 영향을 CPU 사이에 전파하긴 하지만, 순서대로 전파하지는 않을 수 있습니다.
+
+ [*] 버스 마스터링 DMA 와 일관성에 대해서는 다음을 참고하시기 바랍니다:
+
+ Documentation/PCI/pci.txt
+ Documentation/DMA-API-HOWTO.txt
+ Documentation/DMA-API.txt
+
+
+데이터 의존성 배리어
+--------------------
+
+데이터 의존성 배리어의 사용에 있어 지켜야 하는 사항들은 약간 미묘하고, 데이터
+의존성 배리어가 사용되어야 하는 상황도 항상 명백하지는 않습니다. 설명을 위해
+다음의 이벤트 시퀀스를 생각해 봅시다:
+
+ CPU 1 CPU 2
+ =============== ===============
+ { A == 1, B == 2, C == 3, P == &A, Q == &C }
+ B = 4;
+ <쓰기 배리어>
+ WRITE_ONCE(P, &B)
+ Q = READ_ONCE(P);
+ D = *Q;
+
+여기엔 분명한 데이터 의존성이 존재하므로, 이 시퀀스가 끝났을 때 Q 는 &A 또는 &B
+일 것이고, 따라서:
+
+ (Q == &A) 는 (D == 1) 를,
+ (Q == &B) 는 (D == 4) 를 의미합니다.
+
+하지만! CPU 2 는 B 의 업데이트를 인식하기 전에 P 의 업데이트를 인식할 수 있고,
+따라서 다음의 결과가 가능합니다:
+
+ (Q == &B) and (D == 2) ????
+
+이런 결과는 일관성이나 인과 관계 유지가 실패한 것처럼 보일 수도 있겠지만,
+그렇지 않습니다, 그리고 이 현상은 (DEC Alpha 와 같은) 여러 CPU 에서 실제로
+발견될 수 있습니다.
+
+이 문제 상황을 제대로 해결하기 위해, 데이터 의존성 배리어나 그보다 강화된
+무언가가 주소를 읽어올 때와 데이터를 읽어올 때 사이에 추가되어야만 합니다:
+
+ CPU 1 CPU 2
+ =============== ===============
+ { A == 1, B == 2, C == 3, P == &A, Q == &C }
+ B = 4;
+ <쓰기 배리어>
+ WRITE_ONCE(P, &B);
+ Q = READ_ONCE(P);
+ <데이터 의존성 배리어>
+ D = *Q;
+
+이 변경은 앞의 처음 두가지 결과 중 하나만이 발생할 수 있고, 세번째의 결과는
+발생할 수 없도록 합니다.
+
+데이터 의존성 배리어는 의존적 쓰기에 대해서도 순서를 잡아줍니다:
+
+ CPU 1 CPU 2
+ =============== ===============
+ { A == 1, B == 2, C = 3, P == &A, Q == &C }
+ B = 4;
+ <쓰기 배리어>
+ WRITE_ONCE(P, &B);
+ Q = READ_ONCE(P);
+ <데이터 의존성 배리어>
+ *Q = 5;
+
+이 데이터 의존성 배리어는 Q 로의 읽기가 *Q 로의 스토어와 순서를 맞추게
+해줍니다. 이는 다음과 같은 결과를 막습니다:
+
+ (Q == &B) && (B == 4)
+
+이런 패턴은 드물게 사용되어야 함을 알아 두시기 바랍니다. 무엇보다도, 의존성
+순서 규칙의 의도는 쓰기 작업을 -예방- 해서 그로 인해 발생하는 비싼 캐시 미스도
+없애려는 것입니다. 이 패턴은 드물게 발생하는 에러 조건 같은것들을 기록하는데
+사용될 수 있고, 이렇게 배리어를 사용해 순서를 지키게 함으로써 그런 기록이
+사라지는 것을 막습니다.
+
+
+[!] 상당히 비직관적인 이 상황은 분리된 캐시를 가진 기계, 예를 들어 한 캐시
+뱅크가 짝수번 캐시 라인을 처리하고 다른 뱅크는 홀수번 캐시 라인을 처리하는 기계
+등에서 가장 잘 발생합니다. 포인터 P 는 홀수 번호의 캐시 라인에 있고, 변수 B 는
+짝수 번호 캐시 라인에 있다고 생각해 봅시다. 그런 상태에서 읽기 작업을 하는 CPU
+의 짝수번 뱅크는 할 일이 쌓여 매우 바쁘지만 홀수번 뱅크는 할 일이 없어 아무
+일도 하지 않고 있었다면, 포인터 P 는 새 값 (&B) 을, 그리고 변수 B 는 옛날 값
+(2) 을 가지고 있는 상태가 보여질 수도 있습니다.
+
+
+데이터 의존성 배리어는 매우 중요한데, 예를 들어 RCU 시스템에서 그렇습니다.
+include/linux/rcupdate.h 의 rcu_assign_pointer() 와 rcu_dereference() 를
+참고하세요. 여기서 데이터 의존성 배리어는 RCU 로 관리되는 포인터의 타겟을 현재
+타겟에서 수정된 새로운 타겟으로 바꾸는 작업에서 새로 수정된 타겟이 초기화가
+완료되지 않은 채로 보여지는 일이 일어나지 않게 해줍니다.
+
+더 많은 예를 위해선 "캐시 일관성" 서브섹션을 참고하세요.
+
+
+컨트롤 의존성
+-------------
+
+로드-로드 컨트롤 의존성은 데이터 의존성 배리어만으로는 정확히 동작할 수가
+없어서 읽기 메모리 배리어를 필요로 합니다. 아래의 코드를 봅시다:
+
+ q = READ_ONCE(a);
+ if (q) {
+ <데이터 의존성 배리어> /* BUG: No data dependency!!! */
+ p = READ_ONCE(b);
+ }
+
+이 코드는 원하는 대로의 효과를 내지 못할 수 있는데, 이 코드에는 데이터 의존성이
+아니라 컨트롤 의존성이 존재하기 때문으로, 이런 상황에서 CPU 는 실행 속도를 더
+빠르게 하기 위해 분기 조건의 결과를 예측하고 코드를 재배치 할 수 있어서 다른
+CPU 는 b 로부터의 로드 오퍼레이션이 a 로부터의 로드 오퍼레이션보다 먼저 발생한
+걸로 인식할 수 있습니다. 여기에 정말로 필요했던 건 다음과 같습니다:
+
+ q = READ_ONCE(a);
+ if (q) {
+ <읽기 배리어>
+ p = READ_ONCE(b);
+ }
+
+하지만, 스토어 오퍼레이션은 예측적으로 수행되지 않습니다. 즉, 다음 예에서와
+같이 로드-스토어 컨트롤 의존성이 존재하는 경우에는 순서가 -지켜진다-는
+의미입니다.
+
+ q = READ_ONCE(a);
+ if (q) {
+ WRITE_ONCE(b, p);
+ }
+
+컨트롤 의존성은 보통 다른 타입의 배리어들과 짝을 맞춰 사용됩니다. 그렇다곤
+하나, READ_ONCE() 는 반드시 사용해야 함을 부디 명심하세요! READ_ONCE() 가
+없다면, 컴파일러가 'a' 로부터의 로드를 'a' 로부터의 또다른 로드와, 'b' 로의
+스토어를 'b' 로의 또다른 스토어와 조합해 버려 매우 비직관적인 결과를 초래할 수
+있습니다.
+
+이걸로 끝이 아닌게, 컴파일러가 변수 'a' 의 값이 항상 0이 아니라고 증명할 수
+있다면, 앞의 예에서 "if" 문을 없애서 다음과 같이 최적화 할 수도 있습니다:
+
+ q = a;
+ b = p; /* BUG: Compiler and CPU can both reorder!!! */
+
+그러니 READ_ONCE() 를 반드시 사용하세요.
+
+다음과 같이 "if" 문의 양갈래 브랜치에 모두 존재하는 동일한 스토어에 대해 순서를
+강제하고 싶은 경우가 있을 수 있습니다:
+
+ q = READ_ONCE(a);
+ if (q) {
+ barrier();
+ WRITE_ONCE(b, p);
+ do_something();
+ } else {
+ barrier();
+ WRITE_ONCE(b, p);
+ do_something_else();
+ }
+
+안타깝게도, 현재의 컴파일러들은 높은 최적화 레벨에서는 이걸 다음과 같이
+바꿔버립니다:
+
+ q = READ_ONCE(a);
+ barrier();
+ WRITE_ONCE(b, p); /* BUG: No ordering vs. load from a!!! */
+ if (q) {
+ /* WRITE_ONCE(b, p); -- moved up, BUG!!! */
+ do_something();
+ } else {
+ /* WRITE_ONCE(b, p); -- moved up, BUG!!! */
+ do_something_else();
+ }
+
+이제 'a' 에서의 로드와 'b' 로의 스토어 사이에는 조건적 관계가 없기 때문에 CPU
+는 이들의 순서를 바꿀 수 있게 됩니다: 이런 경우에 조건적 관계는 반드시
+필요한데, 모든 컴파일러 최적화가 이루어지고 난 후의 어셈블리 코드에서도
+마찬가지입니다. 따라서, 이 예에서 순서를 지키기 위해서는 smp_store_release()
+와 같은 명시적 메모리 배리어가 필요합니다:
+
+ q = READ_ONCE(a);
+ if (q) {
+ smp_store_release(&b, p);
+ do_something();
+ } else {
+ smp_store_release(&b, p);
+ do_something_else();
+ }
+
+반면에 명시적 메모리 배리어가 없다면, 이런 경우의 순서는 스토어 오퍼레이션들이
+서로 다를 때에만 보장되는데, 예를 들면 다음과 같은 경우입니다:
+
+ q = READ_ONCE(a);
+ if (q) {
+ WRITE_ONCE(b, p);
+ do_something();
+ } else {
+ WRITE_ONCE(b, r);
+ do_something_else();
+ }
+
+처음의 READ_ONCE() 는 컴파일러가 'a' 의 값을 증명해내는 것을 막기 위해 여전히
+필요합니다.
+
+또한, 로컬 변수 'q' 를 가지고 하는 일에 대해 주의해야 하는데, 그러지 않으면
+컴파일러는 그 값을 추측하고 또다시 필요한 조건관계를 없애버릴 수 있습니다.
+예를 들면:
+
+ q = READ_ONCE(a);
+ if (q % MAX) {
+ WRITE_ONCE(b, p);
+ do_something();
+ } else {
+ WRITE_ONCE(b, r);
+ do_something_else();
+ }
+
+만약 MAX 가 1 로 정의된 상수라면, 컴파일러는 (q % MAX) 는 0이란 것을 알아채고,
+위의 코드를 아래와 같이 바꿔버릴 수 있습니다:
+
+ q = READ_ONCE(a);
+ WRITE_ONCE(b, p);
+ do_something_else();
+
+이렇게 되면, CPU 는 변수 'a' 로부터의 로드와 변수 'b' 로의 스토어 사이의 순서를
+지켜줄 필요가 없어집니다. barrier() 를 추가해 해결해 보고 싶겠지만, 그건
+도움이 안됩니다. 조건 관계는 사라졌고, barrier() 는 이를 되돌리지 못합니다.
+따라서, 이 순서를 지켜야 한다면, MAX 가 1 보다 크다는 것을, 다음과 같은 방법을
+사용해 분명히 해야 합니다:
+
+ q = READ_ONCE(a);
+ BUILD_BUG_ON(MAX <= 1); /* Order load from a with store to b. */
+ if (q % MAX) {
+ WRITE_ONCE(b, p);
+ do_something();
+ } else {
+ WRITE_ONCE(b, r);
+ do_something_else();
+ }
+
+'b' 로의 스토어들은 여전히 서로 다름을 알아두세요. 만약 그것들이 동일하면,
+앞에서 이야기했듯, 컴파일러가 그 스토어 오퍼레이션들을 'if' 문 바깥으로
+끄집어낼 수 있습니다.
+
+또한 이진 조건문 평가에 너무 의존하지 않도록 조심해야 합니다. 다음의 예를
+봅시다:
+
+ q = READ_ONCE(a);
+ if (q || 1 > 0)
+ WRITE_ONCE(b, 1);
+
+첫번째 조건만으로는 브랜치 조건 전체를 거짓으로 만들 수 없고 두번째 조건은 항상
+참이기 때문에, 컴파일러는 이 예를 다음과 같이 바꿔서 컨트롤 의존성을 없애버릴
+수 있습니다:
+
+ q = READ_ONCE(a);
+ WRITE_ONCE(b, 1);
+
+이 예는 컴파일러가 코드를 추측으로 수정할 수 없도록 분명히 해야 한다는 점을
+강조합니다. 조금 더 일반적으로 말해서, READ_ONCE() 는 컴파일러에게 주어진 로드
+오퍼레이션을 위한 코드를 정말로 만들도록 하지만, 컴파일러가 그렇게 만들어진
+코드의 수행 결과를 사용하도록 강제하지는 않습니다.
+
+마지막으로, 컨트롤 의존성은 이행성 (transitivity) 을 제공하지 -않습니다-. 이건
+x 와 y 가 둘 다 0 이라는 초기값을 가졌다는 가정 하의 두개의 예제로
+보이겠습니다:
+
+ CPU 0 CPU 1
+ ======================= =======================
+ r1 = READ_ONCE(x); r2 = READ_ONCE(y);
+ if (r1 > 0) if (r2 > 0)
+ WRITE_ONCE(y, 1); WRITE_ONCE(x, 1);
+
+ assert(!(r1 == 1 && r2 == 1));
+
+이 두 CPU 예제에서 assert() 의 조건은 항상 참일 것입니다. 그리고, 만약 컨트롤
+의존성이 이행성을 (실제로는 그러지 않지만) 보장한다면, 다음의 CPU 가 추가되어도
+아래의 assert() 조건은 참이 될것입니다:
+
+ CPU 2
+ =====================
+ WRITE_ONCE(x, 2);
+
+ assert(!(r1 == 2 && r2 == 1 && x == 2)); /* FAILS!!! */
+
+하지만 컨트롤 의존성은 이행성을 제공하지 -않기- 때문에, 세개의 CPU 예제가 실행
+완료된 후에 위의 assert() 의 조건은 거짓으로 평가될 수 있습니다. 세개의 CPU
+예제가 순서를 지키길 원한다면, CPU 0 와 CPU 1 코드의 로드와 스토어 사이, "if"
+문 바로 다음에 smp_mb()를 넣어야 합니다. 더 나아가서, 최초의 두 CPU 예제는
+매우 위험하므로 사용되지 않아야 합니다.
+
+이 두개의 예제는 다음 논문:
+http://www.cl.cam.ac.uk/users/pes20/ppc-supplemental/test6.pdf 와
+이 사이트: https://www.cl.cam.ac.uk/~pes20/ppcmem/index.html 에 나온 LB 와 WWC
+리트머스 테스트입니다.
+
+요약하자면:
+
+ (*) 컨트롤 의존성은 앞의 로드들을 뒤의 스토어들에 대해 순서를 맞춰줍니다.
+ 하지만, 그 외의 어떤 순서도 보장하지 -않습니다-: 앞의 로드와 뒤의 로드들
+ 사이에도, 앞의 스토어와 뒤의 스토어들 사이에도요. 이런 다른 형태의
+ 순서가 필요하다면 smp_rmb() 나 smp_wmb()를, 또는, 앞의 스토어들과 뒤의
+ 로드들 사이의 순서를 위해서는 smp_mb() 를 사용하세요.
+
+ (*) "if" 문의 양갈래 브랜치가 같은 변수에의 동일한 스토어로 시작한다면, 그
+ 스토어들은 각 스토어 앞에 smp_mb() 를 넣거나 smp_store_release() 를
+ 사용해서 스토어를 하는 식으로 순서를 맞춰줘야 합니다. 이 문제를 해결하기
+ 위해 "if" 문의 양갈래 브랜치의 시작 지점에 barrier() 를 넣는 것만으로는
+ 충분한 해결이 되지 않는데, 이는 앞의 예에서 본것과 같이, 컴파일러의
+ 최적화는 barrier() 가 의미하는 바를 지키면서도 컨트롤 의존성을 손상시킬
+ 수 있기 때문이라는 점을 부디 알아두시기 바랍니다.
+
+ (*) 컨트롤 의존성은 앞의 로드와 뒤의 스토어 사이에 최소 하나의, 실행
+ 시점에서의 조건관계를 필요로 하며, 이 조건관계는 앞의 로드와 관계되어야
+ 합니다. 만약 컴파일러가 조건 관계를 최적화로 없앨수 있다면, 순서도
+ 최적화로 없애버렸을 겁니다. READ_ONCE() 와 WRITE_ONCE() 의 주의 깊은
+ 사용은 주어진 조건 관계를 유지하는데 도움이 될 수 있습니다.
+
+ (*) 컨트롤 의존성을 위해선 컴파일러가 조건관계를 없애버리는 것을 막아야
+ 합니다. 주의 깊은 READ_ONCE() 나 atomic{,64}_read() 의 사용이 컨트롤
+ 의존성이 사라지지 않게 하는데 도움을 줄 수 있습니다. 더 많은 정보를
+ 위해선 "컴파일러 배리어" 섹션을 참고하시기 바랍니다.
+
+ (*) 컨트롤 의존성은 보통 다른 타입의 배리어들과 짝을 맞춰 사용됩니다.
+
+ (*) 컨트롤 의존성은 이행성을 제공하지 -않습니다-. 이행성이 필요하다면,
+ smp_mb() 를 사용하세요.

+
+SMP 배리어 짝맞추기
+--------------------
+
+CPU 간 상호작용을 다룰 때에 일부 타입의 메모리 배리어는 항상 짝을 맞춰
+사용되어야 합니다. 적절하게 짝을 맞추지 않은 코드는 사실상 에러에 가깝습니다.
+
+범용 배리어들은 범용 배리어끼리도 짝을 맞추지만 이행성이 없는 대부분의 다른
+타입의 배리어들과도 짝을 맞춥니다. ACQUIRE 배리어는 RELEASE 배리어와 짝을
+맞춥니다만, 둘 다 범용 배리어를 포함해 다른 배리어들과도 짝을 맞출 수 있습니다.
+쓰기 배리어는 데이터 의존성 배리어나 컨트롤 의존성, ACQUIRE 배리어, RELEASE
+배리어, 읽기 배리어, 또는 범용 배리어와 짝을 맞춥니다. 비슷하게 읽기 배리어나
+컨트롤 의존성, 또는 데이터 의존성 배리어는 쓰기 배리어나 ACQUIRE 배리어,
+RELEASE 배리어, 또는 범용 배리어와 짝을 맞추는데, 다음과 같습니다:
+
+ CPU 1 CPU 2
+ =============== ===============
+ WRITE_ONCE(a, 1);
+ <쓰기 배리어>
+ WRITE_ONCE(b, 2); x = READ_ONCE(b);
+ <읽기 배리어>
+ y = READ_ONCE(a);
+
+또는:
+
+ CPU 1 CPU 2
+ =============== ===============================
+ a = 1;
+ <쓰기 배리어>
+ WRITE_ONCE(b, &a); x = READ_ONCE(b);
+ <데이터 의존성 배리어>
+ y = *x;
+
+또는:
+
+ CPU 1 CPU 2
+ =============== ===============================
+ r1 = READ_ONCE(y);
+ <범용 배리어>
+ WRITE_ONCE(y, 1); if (r2 = READ_ONCE(x)) {
+ <묵시적 컨트롤 의존성>
+ WRITE_ONCE(y, 1);
+ }
+
+ assert(r1 == 0 || r2 == 0);
+
+기본적으로, 여기서의 읽기 배리어는 "더 완화된" 타입일 순 있어도 항상 존재해야
+합니다.
+
+[!] 쓰기 배리어 앞의 스토어 오퍼레이션은 일반적으로 읽기 배리어나 데이터
+의존성 배리어 뒤의 로드 오퍼레이션과 매치될 것이고, 반대도 마찬가지입니다:
+
+ CPU 1 CPU 2
+ =================== ===================
+ WRITE_ONCE(a, 1); }---- --->{ v = READ_ONCE(c);
+ WRITE_ONCE(b, 2); } \ / { w = READ_ONCE(d);
+ <쓰기 배리어> \ <읽기 배리어>
+ WRITE_ONCE(c, 3); } / \ { x = READ_ONCE(a);
+ WRITE_ONCE(d, 4); }---- --->{ y = READ_ONCE(b);
+
+
+메모리 배리어 시퀀스의 예
+-------------------------
+
+첫째, 쓰기 배리어는 스토어 오퍼레이션들의 부분적 순서 세우기로 동작합니다.
+아래의 이벤트 시퀀스를 보세요:
+
+ CPU 1
+ =======================
+ STORE A = 1
+ STORE B = 2
+ STORE C = 3
+ <쓰기 배리어>
+ STORE D = 4
+ STORE E = 5
+
+이 이벤트 시퀀스는 메모리 일관성 시스템에 원소끼리의 순서가 존재하지 않는 집합
+{ STORE A, STORE B, STORE C } 가 역시 원소끼리의 순서가 존재하지 않는 집합
+{ STORE D, STORE E } 보다 먼저 일어난 것으로 시스템의 나머지 요소들에 보이도록
+전달됩니다:

+ | | +------+
+ +-------+ : :
+ |
+ | CPU 1 에 의해 메모리 시스템에 전달되는

+ V
+
+
+둘째, 데이터 의존성 배리어는 데이터 의존적 로드 오퍼레이션들의 부분적 순서
+세우기로 동작합니다. 다음 일련의 이벤트들을 보세요:
+
+ CPU 1 CPU 2
+ ======================= =======================
+ { B = 7; X = 9; Y = 8; C = &Y }
+ STORE A = 1
+ STORE B = 2
+ <쓰기 배리어>
+ STORE C = &B LOAD X
+ STORE D = 4 LOAD C (gets &B)
+ LOAD *C (reads B)
+
+여기에 별다른 개입이 없다면, CPU 1 의 쓰기 배리어에도 불구하고 CPU 2 는 CPU 1
+의 이벤트들을 완전히 무작위적 순서로 인지하게 됩니다:
+

+
+
+앞의 예에서, CPU 2 는 (B 의 값이 될) *C 의 값 읽기가 C 의 LOAD 뒤에 이어짐에도
+B 가 7 이라는 결과를 얻습니다.
+
+하지만, 만약 데이터 의존성 배리어가 C 의 로드와 *C (즉, B) 의 로드 사이에
+있었다면:
+
+ CPU 1 CPU 2
+ ======================= =======================
+ { B = 7; X = 9; Y = 8; C = &Y }

+ <쓰기 배리어>
+ STORE C = &B LOAD X
+ STORE D = 4 LOAD C (gets &B)
+ <데이터 의존성 배리어>

+
+다음과 같이 됩니다:

+
+셋째, 읽기 배리어는 로드 오퍼레이션들에의 부분적 순서 세우기로 동작합니다.
+아래의 일련의 이벤트를 봅시다:
+
+ CPU 1 CPU 2
+ ======================= =======================
+ { A = 0, B = 9 }
+ STORE A=1
+ <쓰기 배리어>
+ STORE B=2
+ LOAD B

+
+CPU 1 은 쓰기 배리어를 쳤지만, 별다른 개입이 없다면 CPU 2 는 CPU 1 에서 행해진
+이벤트의 결과를 무작위적 순서로 인지하게 됩니다.

+
+하지만, 만약 읽기 배리어가 B 의 로드와 A 의 로드 사이에 존재한다면:
+
+ CPU 1 CPU 2
+ ======================= =======================
+ { A = 0, B = 9 }
+ STORE A=1
+ <쓰기 배리어>
+ STORE B=2
+ LOAD B

+
+
+더 완벽한 설명을 위해, A 의 로드가 읽기 배리어 앞과 뒤에 있으면 어떻게 될지
+생각해 봅시다:

+ ======================= =======================
+ { A = 0, B = 9 }
+ STORE A=1
+ <쓰기 배리어>
+ STORE B=2
+ LOAD B
+ LOAD A [first load of A]
+ <읽기 배리어>
+ LOAD A [second load of A]
+
+A 의 로드 두개가 모두 B 의 로드 뒤에 있지만, 서로 다른 값을 얻어올 수
+있습니다:

+
+여기서 보장되는 건, 만약 B 의 로드가 B == 2 라는 결과를 봤다면, A 에의 두번째
+로드는 항상 A == 1 을 보게 될 것이라는 겁니다. A 에의 첫번째 로드에는 그런
+보장이 없습니다; A == 0 이거나 A == 1 이거나 둘 중 하나의 결과를 보게 될겁니다.
+
+
+읽기 메모리 배리어 VS 로드 예측
+-------------------------------
+
+많은 CPU들이 로드를 예측적으로 (speculatively) 합니다: 어떤 데이터를 메모리에서
+로드해야 하게 될지 예측을 했다면, 해당 데이터를 로드하는 인스트럭션을 실제로는
+아직 만나지 않았더라도 다른 로드 작업이 없어 버스 (bus) 가 아무 일도 하고 있지
+않다면, 그 데이터를 로드합니다. 이후에 실제 로드 인스트럭션이 실행되면 CPU 가
+이미 그 값을 가지고 있기 때문에 그 로드 인스트럭션은 즉시 완료됩니다.
+
+해당 CPU 는 실제로는 그 값이 필요치 않았다는 사실이 나중에 드러날 수도 있는데 -
+해당 로드 인스트럭션이 브랜치로 우회되거나 했을 수 있겠죠 - , 그렇게 되면 앞서
+읽어둔 값을 버리거나 나중의 사용을 위해 캐시에 넣어둘 수 있습니다.
+
+다음을 생각해 봅시다:
+
+ CPU 1 CPU 2
+ ======================= =======================
+ LOAD B
+ DIVIDE } 나누기 명령은 일반적으로

+ CPU 는 해당 LOAD 를 : : | |
+ 즉각 완료한다 : : +-------+
+
+
+읽기 배리어나 데이터 의존성 배리어를 두번째 로드 직전에 놓는다면:
+
+ CPU 1 CPU 2
+ ======================= =======================
+ LOAD B
+ DIVIDE
+ DIVIDE
+ <읽기 배리어>
+ LOAD A
+
+예측으로 얻어진 값은 사용된 배리어의 타입에 따라서 해당 값이 옳은지 검토되게
+됩니다. 만약 해당 메모리 영역에 변화가 없었다면, 예측으로 얻어두었던 값이
+사용됩니다:
+
+ : : +-------+
+ +-------+ | |
+ --->| B->2 |------>| |

+
+
+하지만 다른 CPU 에서 업데이트나 무효화가 있었다면, 그 예측은 무효화되고 그 값은
+다시 읽혀집니다:
+
+ : : +-------+

+ 업데이트된 값이 다시 읽혀진다 +-------+ | |

+
+
+이행성
+------
+
+이행성(transitivity)은 실제의 컴퓨터 시스템에서 항상 제공되지는 않는, 순서
+맞추기에 대한 상당히 직관적인 개념입니다. 다음의 예가 이행성을 보여줍니다:
+
+ CPU 1 CPU 2 CPU 3
+ ======================= ======================= =======================
+ { X = 0, Y = 0 }
+ STORE X=1 LOAD X STORE Y=1
+ <범용 배리어> <범용 배리어>
+ LOAD Y LOAD X
+
+CPU 2 의 X 로드가 1을 리턴했고 Y 로드가 0을 리턴했다고 해봅시다. 이는 CPU 2 의
+X 로드가 CPU 1 의 X 스토어 뒤에 이루어졌고 CPU 2 의 Y 로드는 CPU 3 의 Y 스토어
+전에 이루어졌음을 의미합니다. 그럼 "CPU 3 의 X 로드는 0을 리턴할 수 있나요?"
+
+CPU 2 의 X 로드는 CPU 1 의 스토어 후에 이루어졌으니, CPU 3 의 X 로드는 1을
+리턴하는게 자연스럽습니다. 이런 생각이 이행성의 한 예입니다: CPU A 에서 실행된
+로드가 CPU B 에서의 같은 변수에 대한 로드를 뒤따른다면, CPU A 의 로드는 CPU B
+의 로드가 내놓은 값과 같거나 그 후의 값을 내놓아야 합니다.
+
+리눅스 커널에서 범용 배리어의 사용은 이행성을 보장합니다. 따라서, 앞의 예에서
+CPU 2 의 X 로드가 1을, Y 로드는 0을 리턴했다면, CPU 3 의 X 로드는 반드시 1을
+리턴합니다.
+
+하지만, 읽기나 쓰기 배리어에 대해서는 이행성이 보장되지 -않습니다-. 예를 들어,
+앞의 예에서 CPU 2 의 범용 배리어가 아래처럼 읽기 배리어로 바뀐 경우를 생각해
+봅시다:
+
+ CPU 1 CPU 2 CPU 3
+ ======================= ======================= =======================
+ { X = 0, Y = 0 }
+ STORE X=1 LOAD X STORE Y=1
+ <읽기 배리어> <범용 배리어>
+ LOAD Y LOAD X
+
+이 코드는 이행성을 갖지 않습니다: 이 예에서는, CPU 2 의 X 로드가 1을
+리턴하고, Y 로드는 0을 리턴하지만 CPU 3 의 X 로드가 0을 리턴하는 것도 완전히
+합법적입니다.
+
+CPU 2 의 읽기 배리어가 자신의 읽기는 순서를 맞춰줘도, CPU 1 의 스토어와의
+순서를 맞춰준다고는 보장할 수 없다는게 핵심입니다. 따라서, CPU 1 과 CPU 2 가
+버퍼나 캐시를 공유하는 시스템에서 이 예제 코드가 실행된다면, CPU 2 는 CPU 1 이
+쓴 값에 좀 빨리 접근할 수 있을 것입니다. 따라서 CPU 1 과 CPU 2 의 접근으로
+조합된 순서를 모든 CPU 가 동의할 수 있도록 하기 위해 범용 배리어가 필요합니다.
+
+범용 배리어는 "글로벌 이행성"을 제공해서, 모든 CPU 들이 오퍼레이션들의 순서에
+동의하게 할 것입니다. 반면, release-acquire 조합은 "로컬 이행성" 만을
+제공해서, 해당 조합이 사용된 CPU 들만이 해당 액세스들의 조합된 순서에 동의함이
+보장됩니다. 예를 들어, 존경스런 Herman Hollerith 의 C 코드로 보면:
+
+ int u, v, x, y, z;
+
+ void cpu0(void)
+ {
+ r0 = smp_load_acquire(&x);
+ WRITE_ONCE(u, 1);
+ smp_store_release(&y, 1);
+ }
+
+ void cpu1(void)
+ {
+ r1 = smp_load_acquire(&y);
+ r4 = READ_ONCE(v);
+ r5 = READ_ONCE(u);
+ smp_store_release(&z, 1);
+ }
+
+ void cpu2(void)
+ {
+ r2 = smp_load_acquire(&z);
+ smp_store_release(&x, 1);
+ }
+
+ void cpu3(void)
+ {
+ WRITE_ONCE(v, 1);
+ smp_mb();
+ r3 = READ_ONCE(u);
+ }
+
+cpu0(), cpu1(), 그리고 cpu2() 는 smp_store_release()/smp_load_acquire() 쌍의
+연결을 통한 로컬 이행성에 동참하고 있으므로, 다음과 같은 결과는 나오지 않을
+겁니다:
+
+ r0 == 1 && r1 == 1 && r2 == 1
+
+더 나아가서, cpu0() 와 cpu1() 사이의 release-acquire 관계로 인해, cpu1() 은
+cpu0() 의 쓰기를 봐야만 하므로, 다음과 같은 결과도 없을 겁니다:
+
+ r1 == 1 && r5 == 0
+
+하지만, release-acquire 타동성은 동참한 CPU 들에만 적용되므로 cpu3() 에는
+적용되지 않습니다. 따라서, 다음과 같은 결과가 가능합니다:
+
+ r0 == 0 && r1 == 1 && r2 == 1 && r3 == 0 && r4 == 0
+
+비슷하게, 다음과 같은 결과도 가능합니다:
+
+ r0 == 0 && r1 == 1 && r2 == 1 && r3 == 0 && r4 == 0 && r5 == 1
+
+cpu0(), cpu1(), 그리고 cpu2() 는 그들의 읽기와 쓰기를 순서대로 보게 되지만,
+release-acquire 체인에 관여되지 않은 CPU 들은 그 순서에 이견을 가질 수
+있습니다. 이런 이견은 smp_load_acquire() 와 smp_store_release() 의 구현에
+사용되는 완화된 메모리 배리어 인스트럭션들은 항상 배리어 앞의 스토어들을 뒤의
+로드들에 앞세울 필요는 없다는 사실에서 기인합니다. 이 말은 cpu3() 는 cpu0() 의
+u 로의 스토어를 cpu1() 의 v 로부터의 로드 뒤에 일어난 것으로 볼 수 있다는
+뜻입니다, cpu0() 와 cpu1() 은 이 두 오퍼레이션이 의도된 순서대로 일어났음에
+모두 동의하는데도 말입니다.
+
+하지만, smp_load_acquire() 는 마술이 아님을 명심하시기 바랍니다. 구체적으로,
+이 함수는 단순히 순서 규칙을 지키며 인자로부터의 읽기를 수행합니다. 이것은
+어떤 특정한 값이 읽힐 것인지는 보장하지 -않습니다-. 따라서, 다음과 같은 결과도
+가능합니다:
+
+ r0 == 0 && r1 == 0 && r2 == 0 && r5 == 0
+
+이런 결과는 어떤 것도 재배치 되지 않는, 순차적 일관성을 가진 가상의
+시스템에서도 일어날 수 있음을 기억해 두시기 바랍니다.
+
+다시 말하지만, 당신의 코드가 글로벌 이행성을 필요로 한다면, 범용 배리어를
+사용하십시오.
+
+
+==================
+명시적 커널 배리어
+==================
+
+리눅스 커널은 서로 다른 단계에서 동작하는 다양한 배리어들을 가지고 있습니다:
+
+ (*) 컴파일러 배리어.
+
+ (*) CPU 메모리 배리어.
+
+ (*) MMIO 쓰기 배리어.
+
+
+컴파일러 배리어
+---------------
+
+리눅스 커널은 컴파일러가 메모리 액세스를 재배치 하는 것을 막아주는 명시적인
+컴파일러 배리어를 가지고 있습니다:
+
+ barrier();
+
+이건 범용 배리어입니다 -- barrier() 의 읽기-읽기 나 쓰기-쓰기 변종은 없습니다.
+하지만, READ_ONCE() 와 WRITE_ONCE() 는 특정 액세스들에 대해서만 동작하는
+barrier() 의 완화된 형태로 볼 수 있습니다.
+
+barrier() 함수는 다음과 같은 효과를 갖습니다:
+
+ (*) 컴파일러가 barrier() 뒤의 액세스들이 barrier() 앞의 액세스보다 앞으로
+ 재배치되지 못하게 합니다. 예를 들어, 인터럽트 핸들러 코드와 인터럽트 당한
+ 코드 사이의 통신을 신중히 하기 위해 사용될 수 있습니다.
+
+ (*) 루프에서, 컴파일러가 루프 조건에 사용된 변수를 매 이터레이션마다
+ 메모리에서 로드하지 않아도 되도록 최적화 하는걸 방지합니다.
+
+READ_ONCE() 와 WRITE_ONCE() 함수는 싱글 쓰레드 코드에서는 문제 없지만 동시성이
+있는 코드에서는 문제가 될 수 있는 모든 최적화를 막습니다. 이런 류의 최적화에
+대한 예를 몇가지 들어보면 다음과 같습니다:
+
+ (*) 컴파일러는 같은 변수에 대한 로드와 스토어를 재배치 할 수 있고, 어떤
+ 경우에는 CPU가 같은 변수로부터의 로드들을 재배치할 수도 있습니다. 이는
+ 다음의 코드가:
+
+ a[0] = x;
+ a[1] = x;
+
+ x 의 예전 값이 a[1] 에, 새 값이 a[0] 에 있게 할 수 있다는 뜻입니다.
+ 컴파일러와 CPU가 이런 일을 못하게 하려면 다음과 같이 해야 합니다:
+
+ a[0] = READ_ONCE(x);
+ a[1] = READ_ONCE(x);
+
+ 즉, READ_ONCE() 와 WRITE_ONCE() 는 여러 CPU 에서 하나의 변수에 가해지는
+ 액세스들에 캐시 일관성을 제공합니다.
+
+ (*) 컴파일러는 같은 변수에 대한 연속적인 로드들을 병합할 수 있습니다. 그런
+ 병합 작업으로 컴파일러는 다음의 코드를:
+
+ while (tmp = a)
+ do_something_with(tmp);
+
+ 다음과 같이, 싱글 쓰레드 코드에서는 말이 되지만 개발자의 의도와 전혀 맞지
+ 않는 방향으로 "최적화" 할 수 있습니다:
+
+ if (tmp = a)
+ for (;;)
+ do_something_with(tmp);
+
+ 컴파일러가 이런 짓을 하지 못하게 하려면 READ_ONCE() 를 사용하세요:
+
+ while (tmp = READ_ONCE(a))
+ do_something_with(tmp);
+
+ (*) 예컨대 레지스터 사용량이 많아 컴파일러가 모든 데이터를 레지스터에 담을 수
+ 없는 경우, 컴파일러는 변수를 다시 로드할 수 있습니다. 따라서 컴파일러는
+ 앞의 예에서 변수 'tmp' 사용을 최적화로 없애버릴 수 있습니다:
+
+ while (tmp = a)
+ do_something_with(tmp);
+
+ 이 코드는 다음과 같이 싱글 쓰레드에서는 완벽하지만 동시성이 존재하는
+ 경우엔 치명적인 코드로 바뀔 수 있습니다:
+
+ while (a)
+ do_something_with(a);
+
+ 예를 들어, 최적화된 이 코드는 변수 a 가 다른 CPU 에 의해 "while" 문과
+ do_something_with() 호출 사이에 바뀌어 do_something_with() 에 0을 넘길
+ 수도 있습니다.
+
+ 이번에도, 컴파일러가 그런 짓을 하는걸 막기 위해 READ_ONCE() 를 사용하세요:
+
+ while (tmp = READ_ONCE(a))
+ do_something_with(tmp);
+
+ 레지스터가 부족한 상황을 겪는 경우, 컴파일러는 tmp 를 스택에 저장해둘 수도
+ 있습니다. 컴파일러가 변수를 다시 읽어들이는건 이렇게 저장해두고 후에 다시
+ 읽어들이는데 드는 오버헤드 때문입니다. 그렇게 하는게 싱글 쓰레드
+ 코드에서는 안전하므로, 안전하지 않은 경우에는 컴파일러에게 직접 알려줘야
+ 합니다.
+
+ (*) 컴파일러는 그 값이 무엇일지 알고 있다면 로드를 아예 안할 수도 있습니다.
+ 예를 들어, 다음의 코드는 변수 'a' 의 값이 항상 0임을 증명할 수 있다면:
+
+ while (tmp = a)
+ do_something_with(tmp);
+
+ 이렇게 최적화 되어버릴 수 있습니다:
+
+ do { } while (0);
+
+ 이 변환은 싱글 쓰레드 코드에서는 도움이 되는데 로드와 브랜치를 제거했기
+ 때문입니다. 문제는 컴파일러가 'a' 의 값을 업데이트 하는건 현재의 CPU 하나
+ 뿐이라는 가정 위에서 증명을 했다는데 있습니다. 만약 변수 'a' 가 공유되어
+ 있다면, 컴파일러의 증명은 틀린 것이 될겁니다. 컴파일러는 그 자신이
+ 생각하는 것만큼 많은 것을 알고 있지 못함을 컴파일러에게 알리기 위해
+ READ_ONCE() 를 사용하세요:
+
+ while (tmp = READ_ONCE(a))
+ do_something_with(tmp);
+
+ 하지만 컴파일러는 READ_ONCE() 뒤에 나오는 값에 대해서도 눈길을 두고 있음을
+ 기억하세요. 예를 들어, 다음의 코드에서 MAX 는 전처리기 매크로로, 1의 값을
+ 갖는다고 해봅시다:
+
+ while ((tmp = READ_ONCE(a)) % MAX)
+ do_something_with(tmp);
+
+ 이렇게 되면 컴파일러는 MAX 를 가지고 수행되는 "%" 오퍼레이터의 결과가 항상
+ 0이라는 것을 알게 되고, 컴파일러가 코드를 실질적으로는 존재하지 않는
+ 것처럼 최적화 하는 것이 허용되어 버립니다. ('a' 변수의 로드는 여전히
+ 행해질 겁니다.)
+
+ (*) 비슷하게, 컴파일러는 변수가 저장하려 하는 값을 이미 가지고 있다는 것을
+ 알면 스토어 자체를 제거할 수 있습니다. 이번에도, 컴파일러는 현재의 CPU
+ 만이 그 변수에 값을 쓰는 오로지 하나의 존재라고 생각하여 공유된 변수에
+ 대해서는 잘못된 일을 하게 됩니다. 예를 들어, 다음과 같은 경우가 있을 수
+ 있습니다:
+
+ a = 0;
+ ... 변수 a 에 스토어를 하지 않는 코드 ...
+ a = 0;
+
+ 컴파일러는 변수 'a' 의 값은 이미 0이라는 것을 알고, 따라서 두번째 스토어를
+ 삭제할 겁니다. 만약 다른 CPU 가 그 사이 변수 'a' 에 다른 값을 썼다면
+ 황당한 결과가 나올 겁니다.
+
+ 컴파일러가 그런 잘못된 추측을 하지 않도록 WRITE_ONCE() 를 사용하세요:
+
+ WRITE_ONCE(a, 0);
+ ... 변수 a 에 스토어를 하지 않는 코드 ...
+ WRITE_ONCE(a, 0);
+
+ (*) 컴파일러는 하지 말라고 하지 않으면 메모리 액세스들을 재배치 할 수
+ 있습니다. 예를 들어, 다음의 프로세스 레벨 코드와 인터럽트 핸들러 사이의
+ 상호작용을 생각해 봅시다:
+
+ void process_level(void)
+ {
+ msg = get_message();
+ flag = true;
+ }
+
+ void interrupt_handler(void)
+ {
+ if (flag)
+ process_message(msg);
+ }
+
+ 이 코드에는 컴파일러가 process_level() 을 다음과 같이 변환하는 것을 막을
+ 수단이 없고, 이런 변환은 싱글쓰레드에서라면 실제로 훌륭한 선택일 수
+ 있습니다:
+
+ void process_level(void)
+ {
+ flag = true;
+ msg = get_message();
+ }
+
+ 이 두개의 문장 사이에 인터럽트가 발생한다면, interrupt_handler() 는 의미를
+ 알 수 없는 메세지를 받을 수도 있습니다. 이걸 막기 위해 다음과 같이
+ WRITE_ONCE() 를 사용하세요:
+
+ void process_level(void)
+ {
+ WRITE_ONCE(msg, get_message());
+ WRITE_ONCE(flag, true);
+ }
+
+ void interrupt_handler(void)
+ {
+ if (READ_ONCE(flag))
+ process_message(READ_ONCE(msg));
+ }
+
+ interrupt_handler() 안에서도 중첩된 인터럽트나 NMI 와 같이 인터럽트 핸들러
+ 역시 'flag' 와 'msg' 에 접근하는 또다른 무언가에 인터럽트 될 수 있다면
+ READ_ONCE() 와 WRITE_ONCE() 를 사용해야 함을 기억해 두세요. 만약 그런
+ 가능성이 없다면, interrupt_handler() 안에서는 문서화 목적이 아니라면
+ READ_ONCE() 와 WRITE_ONCE() 는 필요치 않습니다. (근래의 리눅스 커널에서
+ 중첩된 인터럽트는 보통 잘 일어나지 않음도 기억해 두세요, 실제로, 어떤
+ 인터럽트 핸들러가 인터럽트가 활성화된 채로 리턴하면 WARN_ONCE() 가
+ 실행됩니다.)
+
+ 컴파일러는 READ_ONCE() 와 WRITE_ONCE() 뒤의 READ_ONCE() 나 WRITE_ONCE(),
+ barrier(), 또는 비슷한 것들을 담고 있지 않은 코드를 움직일 수 있을 것으로
+ 가정되어야 합니다.
+
+ 이 효과는 barrier() 를 통해서도 만들 수 있지만, READ_ONCE() 와
+ WRITE_ONCE() 가 좀 더 안목 높은 선택입니다: READ_ONCE() 와 WRITE_ONCE()는
+ 컴파일러에 주어진 메모리 영역에 대해서만 최적화 가능성을 포기하도록
+ 하지만, barrier() 는 컴파일러가 지금까지 기계의 레지스터에 캐시해 놓은
+ 모든 메모리 영역의 값을 버려야 하게 하기 때문입니다. 물론, 컴파일러는
+ READ_ONCE() 와 WRITE_ONCE() 가 일어난 순서도 지켜줍니다, CPU 는 당연히
+ 그 순서를 지킬 의무가 없지만요.
+
+ (*) 컴파일러는 다음의 예에서와 같이 변수에의 스토어를 날조해낼 수도 있습니다:
+
+ if (a)
+ b = a;
+ else
+ b = 42;
+
+ 컴파일러는 아래와 같은 최적화로 브랜치를 줄일 겁니다:
+
+ b = 42;
+ if (a)
+ b = a;
+
+ 싱글 쓰레드 코드에서 이 최적화는 안전할 뿐 아니라 브랜치 갯수를
+ 줄여줍니다. 하지만 안타깝게도, 동시성이 있는 코드에서는 이 최적화는 다른
+ CPU 가 'b' 를 로드할 때, -- 'a' 가 0이 아닌데도 -- 가짜인 값, 42를 보게
+ 되는 경우를 가능하게 합니다. 이걸 방지하기 위해 WRITE_ONCE() 를
+ 사용하세요:
+
+ if (a)
+ WRITE_ONCE(b, a);
+ else
+ WRITE_ONCE(b, 42);
+
+ 컴파일러는 로드를 만들어낼 수도 있습니다. 일반적으로는 문제를 일으키지
+ 않지만, 캐시 라인 바운싱을 일으켜 성능과 확장성을 떨어뜨릴 수 있습니다.
+ 날조된 로드를 막기 위해선 READ_ONCE() 를 사용하세요.
+
+ (*) 정렬된 메모리 주소에 위치한, 한번의 메모리 참조 인스트럭션으로 액세스
+ 가능한 크기의 데이터는 하나의 큰 액세스가 여러개의 작은 액세스들로
+ 대체되는 "로드 티어링(load tearing)" 과 "스토어 티어링(store tearing)" 을
+ 방지합니다. 예를 들어, 주어진 아키텍쳐가 7-bit imeediate field 를 갖는
+ 16-bit 스토어 인스트럭션을 제공한다면, 컴파일러는 다음의 32-bit 스토어를
+ 구현하는데에 두개의 16-bit store-immediate 명령을 사용하려 할겁니다:
+
+ p = 0x00010002;
+
+ 스토어 할 상수를 만들고 그 값을 스토어 하기 위해 두개가 넘는 인스트럭션을
+ 사용하게 되는, 이런 종류의 최적화를 GCC 는 실제로 함을 부디 알아 두십시오.
+ 이 최적화는 싱글 쓰레드 코드에서는 성공적인 최적화 입니다. 실제로, 근래에
+ 발생한 (그리고 고쳐진) 버그는 GCC 가 volatile 스토어에 비정상적으로 이
+ 최적화를 사용하게 했습니다. 그런 버그가 없다면, 다음의 예에서
+ WRITE_ONCE() 의 사용은 스토어 티어링을 방지합니다:
+
+ WRITE_ONCE(p, 0x00010002);
+
+ Packed 구조체의 사용 역시 다음의 예처럼 로드 / 스토어 티어링을 유발할 수
+ 있습니다:
+
+ struct __attribute__((__packed__)) foo {
+ short a;
+ int b;
+ short c;
+ };
+ struct foo foo1, foo2;
+ ...
+
+ foo2.a = foo1.a;
+ foo2.b = foo1.b;
+ foo2.c = foo1.c;
+
+ READ_ONCE() 나 WRITE_ONCE() 도 없고 volatile 마킹도 없기 때문에,
+ 컴파일러는 이 세개의 대입문을 두개의 32-bit 로드와 두개의 32-bit 스토어로
+ 변환할 수 있습니다. 이는 'foo1.b' 의 값의 로드 티어링과 'foo2.b' 의
+ 스토어 티어링을 초래할 겁니다. 이 예에서도 READ_ONCE() 와 WRITE_ONCE()
+ 가 티어링을 막을 수 있습니다:
+
+ foo2.a = foo1.a;
+ WRITE_ONCE(foo2.b, READ_ONCE(foo1.b));
+ foo2.c = foo1.c;
+
+그렇지만, volatile 로 마크된 변수에 대해서는 READ_ONCE() 와 WRITE_ONCE() 가
+필요치 않습니다. 예를 들어, 'jiffies' 는 volatile 로 마크되어 있기 때문에,
+READ_ONCE(jiffies) 라고 할 필요가 없습니다. READ_ONCE() 와 WRITE_ONCE() 가
+실은 volatile 캐스팅으로 구현되어 있어서 인자가 이미 volatile 로 마크되어
+있다면 또다른 효과를 내지는 않기 때문입니다.
+
+이 컴파일러 배리어들은 CPU 에는 직접적 효과를 전혀 만들지 않기 때문에, 결국은
+재배치가 일어날 수도 있음을 부디 기억해 두십시오.
+
+
+CPU 메모리 배리어
+-----------------
+
+리눅스 커널은 다음의 여덟개 기본 CPU 메모리 배리어를 가지고 있습니다:
+
+ TYPE MANDATORY SMP CONDITIONAL
+ =============== ======================= ===========================
+ 범용 mb() smp_mb()
+ 쓰기 wmb() smp_wmb()
+ 읽기 rmb() smp_rmb()
+ 데이터 의존성 read_barrier_depends() smp_read_barrier_depends()
+
+
+데이터 의존성 배리어를 제외한 모든 메모리 배리어는 컴파일러 배리어를
+포함합니다. 데이터 의존성은 컴파일러에의 추가적인 순서 보장을 포함하지
+않습니다.
+
+방백: 데이터 의존성이 있는 경우, 컴파일러는 해당 로드를 올바른 순서로 일으킬
+것으로 (예: `a[b]` 는 a[b] 를 로드 하기 전에 b 의 값을 먼저 로드한다)
+기대되지만, C 언어 사양에는 컴파일러가 b 의 값을 추측 (예: 1 과 같음) 해서
+b 로드 전에 a 로드를 하는 코드 (예: tmp = a[1]; if (b != 1) tmp = a[b]; ) 를
+만들지 않아야 한다는 내용 같은 건 없습니다. 또한 컴파일러는 a[b] 를 로드한
+후에 b 를 또다시 로드할 수도 있어서, a[b] 보다 최신 버전의 b 값을 가질 수도
+있습니다. 이런 문제들의 해결책에 대한 의견 일치는 아직 없습니다만, 일단
+READ_ONCE() 매크로부터 보기 시작하는게 좋은 시작이 될겁니다.
+
+SMP 메모리 배리어들은 유니프로세서로 컴파일된 시스템에서는 컴파일러 배리어로
+바뀌는데, 하나의 CPU 는 스스로 일관성을 유지하고, 겹치는 액세스들 역시 올바른
+순서로 행해질 것으로 생각되기 때문입니다. 하지만, 아래의 "Virtual Machine
+Guests" 서브섹션을 참고하십시오.
+
+[!] SMP 시스템에서 공유메모리로의 접근들을 순서 세워야 할 때, SMP 메모리
+배리어는 _반드시_ 사용되어야 함을 기억하세요, 그대신 락을 사용하는 것으로도
+충분하긴 하지만 말이죠.
+
+Mandatory 배리어들은 SMP 시스템에서도 UP 시스템에서도 SMP 효과만 통제하기에는
+불필요한 오버헤드를 갖기 때문에 SMP 효과만 통제하면 되는 곳에는 사용되지 않아야
+합니다. 하지만, 느슨한 순서 규칙의 메모리 I/O 윈도우를 통한 MMIO 의 효과를
+통제할 때에는 mandatory 배리어들이 사용될 수 있습니다. 이 배리어들은
+컴파일러와 CPU 모두 재배치를 못하도록 함으로써 메모리 오퍼레이션들이 디바이스에
+보여지는 순서에도 영향을 주기 때문에, SMP 가 아닌 시스템이라 할지라도 필요할 수
+있습니다.
+
+
+일부 고급 배리어 함수들도 있습니다:
+
+ (*) smp_store_mb(var, value)
+
+ 이 함수는 특정 변수에 특정 값을 대입하고 범용 메모리 배리어를 칩니다.
+ UP 컴파일에서는 컴파일러 배리어보다 더한 것을 친다고는 보장되지 않습니다.
+
+
+ (*) smp_mb__before_atomic();
+ (*) smp_mb__after_atomic();
+
+ 이것들은 값을 리턴하지 않는 (더하기, 빼기, 증가, 감소와 같은) 어토믹
+ 함수들을 위한, 특히 그것들이 레퍼런스 카운팅에 사용될 때를 위한
+ 함수들입니다. 이 함수들은 메모리 배리어를 내포하고 있지는 않습니다.
+
+ 이것들은 값을 리턴하지 않으며 어토믹한 (set_bit 과 clear_bit 같은) 비트
+ 연산에도 사용될 수 있습니다.
+
+ 한 예로, 객체 하나를 무효한 것으로 표시하고 그 객체의 레퍼런스 카운트를
+ 감소시키는 다음 코드를 보세요:
+
+ obj->dead = 1;
+ smp_mb__before_atomic();
+ atomic_dec(&obj->ref_count);
+
+ 이 코드는 객체의 업데이트된 death 마크가 레퍼런스 카운터 감소 동작
+ *전에* 보일 것을 보장합니다.
+
+ 더 많은 정보를 위해선 Documentation/atomic_ops.txt 문서를 참고하세요.
+ 어디서 이것들을 사용해야 할지 궁금하다면 "어토믹 오퍼레이션" 서브섹션을
+ 참고하세요.
+
+
+ (*) lockless_dereference();
+
+ 이 함수는 smp_read_barrier_depends() 데이터 의존성 배리어를 사용하는
+ 포인터 읽어오기 래퍼(wrapper) 함수로 생각될 수 있습니다.
+
+ 객체의 라이프타임이 RCU 외의 메커니즘으로 관리된다는 점을 제외하면
+ rcu_dereference() 와도 유사한데, 예를 들면 객체가 시스템이 꺼질 때에만
+ 제거되는 경우 등입니다. 또한, lockless_dereference() 은 RCU 와 함께
+ 사용될수도, RCU 없이 사용될 수도 있는 일부 데이터 구조에 사용되고
+ 있습니다.
+
+
+ (*) dma_wmb();
+ (*) dma_rmb();
+
+ 이것들은 CPU 와 DMA 가능한 디바이스에서 모두 액세스 가능한 공유 메모리의
+ 읽기, 쓰기 작업들의 순서를 보장하기 위해 consistent memory 에서 사용하기
+ 위한 것들입니다.
+
+ 예를 들어, 디바이스와 메모리를 공유하며, 디스크립터 상태 값을 사용해
+ 디스크립터가 디바이스에 속해 있는지 아니면 CPU 에 속해 있는지 표시하고,
+ 공지용 초인종(doorbell) 을 사용해 업데이트된 디스크립터가 디바이스에 사용
+ 가능해졌음을 공지하는 디바이스 드라이버를 생각해 봅시다:
+
+ if (desc->status != DEVICE_OWN) {
+ /* 디스크립터를 소유하기 전에는 데이터를 읽지 않음 */
+ dma_rmb();
+
+ /* 데이터를 읽고 씀 */
+ read_data = desc->data;
+ desc->data = write_data;
+
+ /* 상태 업데이트 전 수정사항을 반영 */
+ dma_wmb();
+
+ /* 소유권을 수정 */
+ desc->status = DEVICE_OWN;
+
+ /* MMIO 를 통해 디바이스에 공지를 하기 전에 메모리를 동기화 */
+ wmb();
+
+ /* 업데이트된 디스크립터의 디바이스에 공지 */
+ writel(DESC_NOTIFY, doorbell);
+ }
+
+ dma_rmb() 는 디스크립터로부터 데이터를 읽어오기 전에 디바이스가 소유권을
+ 내놓았음을 보장하게 하고, dma_wmb() 는 디바이스가 자신이 소유권을 다시
+ 가졌음을 보기 전에 디스크립터에 데이터가 쓰였음을 보장합니다. wmb() 는
+ 캐시 일관성이 없는 (cache incoherent) MMIO 영역에 쓰기를 시도하기 전에
+ 캐시 일관성이 있는 메모리 (cache coherent memory) 쓰기가 완료되었음을
+ 보장해주기 위해 필요합니다.
+
+ consistent memory 에 대한 자세한 내용을 위해선 Documentation/DMA-API.txt
+ 문서를 참고하세요.
+
+
+MMIO 쓰기 배리어
+----------------
+
+리눅스 커널은 또한 memory-mapped I/O 쓰기를 위한 특별한 배리어도 가지고
+있습니다:
+
+ mmiowb();
+
+이것은 mandatory 쓰기 배리어의 변종으로, 완화된 순서 규칙의 I/O 영역에으로의
+쓰기가 부분적으로 순서를 맞추도록 해줍니다. 이 함수는 CPU->하드웨어 사이를
+넘어서 실제 하드웨어에까지 일부 수준의 영향을 끼칩니다.
+
+더 많은 정보를 위해선 "Acquire vs I/O 액세스" 서브섹션을 참고하세요.
+
+
+=========================
+암묵적 커널 메모리 배리어
+=========================
+
+리눅스 커널의 일부 함수들은 메모리 배리어를 내장하고 있는데, 락(lock)과
+스케쥴링 관련 함수들이 대부분입니다.
+
+여기선 _최소한의_ 보장을 설명합니다; 특정 아키텍쳐에서는 이 설명보다 더 많은
+보장을 제공할 수도 있습니다만 해당 아키텍쳐에 종속적인 코드 외의 부분에서는
+그런 보장을 기대해선 안될겁니다.
+
+
+락 ACQUISITION 함수
+-------------------
+
+리눅스 커널은 다양한 락 구성체를 가지고 있습니다:
+
+ (*) 스핀 락
+ (*) R/W 스핀 락
+ (*) 뮤텍스
+ (*) 세마포어
+ (*) R/W 세마포어
+
+각 구성체마다 모든 경우에 "ACQUIRE" 오퍼레이션과 "RELEASE" 오퍼레이션의 변종이
+존재합니다. 이 오퍼레이션들은 모두 적절한 배리어를 내포하고 있습니다:
+
+ (1) ACQUIRE 오퍼레이션의 영향:
+
+ ACQUIRE 뒤에서 요청된 메모리 오퍼레이션은 ACQUIRE 오퍼레이션이 완료된
+ 뒤에 완료됩니다.
+
+ ACQUIRE 앞에서 요청된 메모리 오퍼레이션은 ACQUIRE 오퍼레이션이 완료된 후에
+ 완료될 수 있습니다. smp_mb__before_spinlock() 뒤에 ACQUIRE 가 실행되는
+ 코드 블록은 블록 앞의 스토어를 블록 뒤의 로드와 스토어에 대해 순서
+ 맞춥니다. 이건 smp_mb() 보다 완화된 것임을 기억하세요! 많은 아키텍쳐에서
+ smp_mb__before_spinlock() 은 사실 아무일도 하지 않습니다.
+
+ (2) RELEASE 오퍼레이션의 영향:
+
+ RELEASE 앞에서 요청된 메모리 오퍼레이션은 RELEASE 오퍼레이션이 완료되기
+ 전에 완료됩니다.
+
+ RELEASE 뒤에서 요청된 메모리 오퍼레이션은 RELEASE 오퍼레이션 완료 전에
+ 완료될 수 있습니다.
+
+ (3) ACQUIRE vs ACQUIRE 영향:
+
+ 어떤 ACQUIRE 오퍼레이션보다 앞에서 요청된 모든 ACQUIRE 오퍼레이션은 그
+ ACQUIRE 오퍼레이션 전에 완료됩니다.
+
+ (4) ACQUIRE vs RELEASE implication:
+
+ 어떤 RELEASE 오퍼레이션보다 앞서 요청된 ACQUIRE 오퍼레이션은 그 RELEASE
+ 오퍼레이션보다 먼저 완료됩니다.
+
+ (5) 실패한 조건적 ACQUIRE 영향:
+
+ ACQUIRE 오퍼레이션의 일부 락(lock) 변종은 락이 곧바로 획득하기에는
+ 불가능한 상태이거나 락이 획득 가능해지도록 기다리는 도중 시그널을 받거나
+ 해서 실패할 수 있습니다. 실패한 락은 어떤 배리어도 내포하지 않습니다.
+
+[!] 참고: 락 ACQUIRE 와 RELEASE 가 단방향 배리어여서 나타나는 현상 중 하나는
+크리티컬 섹션 바깥의 인스트럭션의 영향이 크리티컬 섹션 내부로도 들어올 수
+있다는 것입니다.
+
+RELEASE 후에 요청되는 ACQUIRE 는 전체 메모리 배리어라 여겨지면 안되는데,
+ACQUIRE 앞의 액세스가 ACQUIRE 후에 수행될 수 있고, RELEASE 후의 액세스가
+RELEASE 전에 수행될 수도 있으며, 그 두개의 액세스가 서로를 지나칠 수도 있기
+때문입니다:
+
+ *A = a;
+ ACQUIRE M
+ RELEASE M
+ *B = b;
+
+는 다음과 같이 될 수도 있습니다:
+
+ ACQUIRE M, STORE *B, STORE *A, RELEASE M
+
+ACQUIRE 와 RELEASE 가 락 획득과 해제라면, 그리고 락의 ACQUIRE 와 RELEASE 가
+같은 락 변수에 대한 것이라면, 해당 락을 쥐고 있지 않은 다른 CPU 의 시야에는
+이와 같은 재배치가 일어나는 것으로 보일 수 있습니다. 요약하자면, ACQUIRE 에
+이어 RELEASE 오퍼레이션을 순차적으로 실행하는 행위가 전체 메모리 배리어로
+생각되어선 -안됩니다-.
+
+비슷하게, 앞의 반대 케이스인 RELEASE 와 ACQUIRE 두개 오퍼레이션의 순차적 실행
+역시 전체 메모리 배리어를 내포하지 않습니다. 따라서, RELEASE, ACQUIRE 로
+규정되는 크리티컬 섹션의 CPU 수행은 RELEASE 와 ACQUIRE 를 가로지를 수 있으므로,
+다음과 같은 코드는:
+
+ *A = a;
+ RELEASE M
+ ACQUIRE N
+ *B = b;
+
+다음과 같이 수행될 수 있습니다:
+
+ ACQUIRE N, STORE *B, STORE *A, RELEASE M
+
+이런 재배치는 데드락을 일으킬 수도 있을 것처럼 보일 수 있습니다. 하지만, 그런
+데드락의 조짐이 있다면 RELEASE 는 단순히 완료될 것이므로 데드락은 존재할 수
+없습니다.
+
+ 이게 어떻게 올바른 동작을 할 수 있을까요?
+
+ 우리가 이야기 하고 있는건 재배치를 하는 CPU 에 대한 이야기이지,
+ 컴파일러에 대한 것이 아니란 점이 핵심입니다. 컴파일러 (또는, 개발자)
+ 가 오퍼레이션들을 이렇게 재배치하면, 데드락이 일어날 수 -있습-니다.
+
+ 하지만 CPU 가 오퍼레이션들을 재배치 했다는걸 생각해 보세요. 이 예에서,
+ 어셈블리 코드 상으로는 언락이 락을 앞서게 되어 있습니다. CPU 가 이를
+ 재배치해서 뒤의 락 오퍼레이션을 먼저 실행하게 됩니다. 만약 데드락이
+ 존재한다면, 이 락 오퍼레이션은 그저 스핀을 하며 계속해서 락을
+ 시도합니다 (또는, 한참 후에겠지만, 잠듭니다). CPU 는 언젠가는
+ (어셈블리 코드에서는 락을 앞서는) 언락 오퍼레이션을 실행하는데, 이 언락
+ 오퍼레이션이 잠재적 데드락을 해결하고, 락 오퍼레이션도 뒤이어 성공하게
+ 됩니다.
+
+ 하지만 만약 락이 잠을 자는 타입이었다면요? 그런 경우에 코드는
+ 스케쥴러로 들어가려 할 거고, 여기서 결국은 메모리 배리어를 만나게
+ 되는데, 이 메모리 배리어는 앞의 언락 오퍼레이션이 완료되도록 만들고,
+ 데드락은 이번에도 해결됩니다. 잠을 자는 행위와 언락 사이의 경주 상황
+ (race) 도 있을 수 있겠습니다만, 락 관련 기능들은 그런 경주 상황을 모든
+ 경우에 제대로 해결할 수 있어야 합니다.
+
+락과 세마포어는 UP 컴파일된 시스템에서의 순서에 대해 보장을 하지 않기 때문에,
+그런 상황에서 인터럽트 비활성화 오퍼레이션과 함께가 아니라면 어떤 일에도 - 특히
+I/O 액세스와 관련해서는 - 제대로 사용될 수 없을 겁니다.
+
+"CPU 간 ACQUIRING 배리어 효과" 섹션도 참고하시기 바랍니다.
+
+
+예를 들어, 다음과 같은 코드를 생각해 봅시다:
+
+ *A = a;
+ *B = b;
+ ACQUIRE
+ *C = c;
+ *D = d;
+ RELEASE
+ *E = e;
+ *F = f;
+
+여기선 다음의 이벤트 시퀀스가 생길 수 있습니다:
+
+ ACQUIRE, {*F,*A}, *E, {*C,*D}, *B, RELEASE
+
+ [+] {*F,*A} 는 조합된 액세스를 의미합니다.
+
+하지만 다음과 같은 건 불가능하죠:
+
+ {*F,*A}, *B, ACQUIRE, *C, *D, RELEASE, *E
+ *A, *B, *C, ACQUIRE, *D, RELEASE, *E, *F
+ *A, *B, ACQUIRE, *C, RELEASE, *D, *E, *F
+ *B, ACQUIRE, *C, *D, RELEASE, {*F,*A}, *E
+
+
+
+인터럽트 비활성화 함수
+----------------------
+
+인터럽트를 비활성화 하는 함수 (ACQUIRE 와 동일) 와 인터럽트를 활성화 하는 함수
+(RELEASE 와 동일) 는 컴파일러 배리어처럼만 동작합니다. 따라서, 별도의 메모리
+배리어나 I/O 배리어가 필요한 상황이라면 그 배리어들은 인터럽트 비활성화 함수
+외의 방법으로 제공되어야만 합니다.
+
+
+슬립과 웨이크업 함수
+--------------------
+
+글로벌 데이터에 표시된 이벤트에 의해 프로세스를 잠에 빠트리는 것과 깨우는 것은
+해당 이벤트를 기다리는 태스크의 태스크 상태와 그 이벤트를 알리기 위해 사용되는
+글로벌 데이터, 두 데이터간의 상호작용으로 볼 수 있습니다. 이것이 옳은 순서대로
+일어남을 분명히 하기 위해, 프로세스를 잠에 들게 하는 기능과 깨우는 기능은
+몇가지 배리어를 내포합니다.
+
+먼저, 잠을 재우는 쪽은 일반적으로 다음과 같은 이벤트 시퀀스를 따릅니다:
+
+ for (;;) {
+ set_current_state(TASK_UNINTERRUPTIBLE);
+ if (event_indicated)
+ break;
+ schedule();
+ }
+
+set_current_state() 에 의해, 태스크 상태가 바뀐 후 범용 메모리 배리어가
+자동으로 삽입됩니다:
+
+ CPU 1
+ ===============================
+ set_current_state();
+ smp_store_mb();
+ STORE current->state
+ <범용 배리어>
+ LOAD event_indicated
+
+set_current_state() 는 다음의 것들로 감싸질 수도 있습니다:
+
+ prepare_to_wait();
+ prepare_to_wait_exclusive();
+
+이것들 역시 상태를 설정한 후 범용 메모리 배리어를 삽입합니다.
+앞의 전체 시퀀스는 다음과 같은 함수들로 한번에 수행 가능한데, 이것들은 모두
+올바른 장소에 메모리 배리어를 삽입합니다:
+
+ wait_event();
+ wait_event_interruptible();
+ wait_event_interruptible_exclusive();
+ wait_event_interruptible_timeout();
+ wait_event_killable();
+ wait_event_timeout();
+ wait_on_bit();
+ wait_on_bit_lock();
+
+
+두번째로, 깨우기를 수행하는 코드는 일반적으로 다음과 같을 겁니다:
+
+ event_indicated = 1;
+ wake_up(&event_wait_queue);
+
+또는:
+
+ event_indicated = 1;
+ wake_up_process(event_daemon);
+
+wake_up() 류에 의해 쓰기 메모리 배리어가 내포됩니다. 만약 그것들이 뭔가를
+깨운다면요. 이 배리어는 태스크 상태가 지워지기 전에 수행되므로, 이벤트를
+알리기 위한 STORE 와 태스크 상태를 TASK_RUNNING 으로 설정하는 STORE 사이에
+위치하게 됩니다.
+
+ CPU 1 CPU 2
+ =============================== ===============================
+ set_current_state(); STORE event_indicated
+ smp_store_mb(); wake_up();
+ STORE current->state <쓰기 배리어>
+ <범용 배리어> STORE current->state
+ LOAD event_indicated
+
+한번더 말합니다만, 이 쓰기 메모리 배리어는 이 코드가 정말로 뭔가를 깨울 때에만
+실행됩니다. 이걸 설명하기 위해, X 와 Y 는 모두 0 으로 초기화 되어 있다는 가정
+하에 아래의 이벤트 시퀀스를 생각해 봅시다:
+
+ CPU 1 CPU 2
+ =============================== ===============================
+ X = 1; STORE event_indicated
+ smp_mb(); wake_up();
+ Y = 1; wait_event(wq, Y == 1);
+ wake_up(); load from Y sees 1, no memory barrier
+ load from X might see 0
+
+위 예제에서의 경우와 달리 깨우기가 정말로 행해졌다면, CPU 2 의 X 로드는 1 을
+본다고 보장될 수 있을 겁니다.
+
+사용 가능한 깨우기류 함수들로 다음과 같은 것들이 있습니다:
+
+ complete();
+ wake_up();
+ wake_up_all();
+ wake_up_bit();
+ wake_up_interruptible();
+ wake_up_interruptible_all();
+ wake_up_interruptible_nr();
+ wake_up_interruptible_poll();
+ wake_up_interruptible_sync();
+ wake_up_interruptible_sync_poll();
+ wake_up_locked();
+ wake_up_locked_poll();
+ wake_up_nr();
+ wake_up_poll();
+ wake_up_process();
+
+
+[!] 잠재우는 코드와 깨우는 코드에 내포되는 메모리 배리어들은 깨우기 전에
+이루어진 스토어를 잠재우는 코드가 set_current_state() 를 호출한 후에 행하는
+로드에 대해 순서를 맞추지 _않는다는_ 점을 기억하세요. 예를 들어, 잠재우는
+코드가 다음과 같고:
+
+ set_current_state(TASK_INTERRUPTIBLE);
+ if (event_indicated)
+ break;
+ __set_current_state(TASK_RUNNING);
+ do_something(my_data);
+
+깨우는 코드는 다음과 같다면:
+
+ my_data = value;
+ event_indicated = 1;
+ wake_up(&event_wait_queue);
+
+event_indecated 에의 변경이 잠재우는 코드에게 my_data 에의 변경 후에 이루어진
+것으로 인지될 것이라는 보장이 없습니다. 이런 경우에는 양쪽 코드 모두 각각의
+데이터 액세스 사이에 메모리 배리어를 직접 쳐야 합니다. 따라서 앞의 재우는
+코드는 다음과 같이:
+
+ set_current_state(TASK_INTERRUPTIBLE);
+ if (event_indicated) {
+ smp_rmb();
+ do_something(my_data);
+ }
+
+그리고 깨우는 코드는 다음과 같이 되어야 합니다:
+
+ my_data = value;
+ smp_wmb();
+ event_indicated = 1;
+ wake_up(&event_wait_queue);
+
+
+그외의 함수들
+-------------
+
+그외의 배리어를 내포하는 함수들은 다음과 같습니다:
+
+ (*) schedule() 과 그 유사한 것들이 완전한 메모리 배리어를 내포합니다.
+
+
+==============================
+CPU 간 ACQUIRING 배리어의 효과
+==============================
+
+SMP 시스템에서의 락 기능들은 더욱 강력한 형태의 배리어를 제공합니다: 이
+배리어는 동일한 락을 사용하는 다른 CPU 들의 메모리 액세스 순서에도 영향을
+끼칩니다.
+
+
+ACQUIRE VS 메모리 액세스
+------------------------
+
+다음의 예를 생각해 봅시다: 시스템은 두개의 스핀락 (M) 과 (Q), 그리고 세개의 CPU
+를 가지고 있습니다; 여기에 다음의 이벤트 시퀀스가 발생합니다:
+
+ CPU 1 CPU 2
+ =============================== ===============================
+ WRITE_ONCE(*A, a); WRITE_ONCE(*E, e);
+ ACQUIRE M ACQUIRE Q
+ WRITE_ONCE(*B, b); WRITE_ONCE(*F, f);
+ WRITE_ONCE(*C, c); WRITE_ONCE(*G, g);
+ RELEASE M RELEASE Q
+ WRITE_ONCE(*D, d); WRITE_ONCE(*H, h);
+
+*A 로의 액세스부터 *H 로의 액세스까지가 어떤 순서로 CPU 3 에게 보여질지에
+대해서는 각 CPU 에서의 락 사용에 의해 내포되어 있는 제약을 제외하고는 어떤
+보장도 존재하지 않습니다. 예를 들어, CPU 3 에게 다음과 같은 순서로 보여지는
+것이 가능합니다:
+
+ *E, ACQUIRE M, ACQUIRE Q, *G, *C, *F, *A, *B, RELEASE Q, *D, *H, RELEASE M
+
+하지만 다음과 같이 보이지는 않을 겁니다:
+
+ *B, *C or *D preceding ACQUIRE M
+ *A, *B or *C following RELEASE M
+ *F, *G or *H preceding ACQUIRE Q
+ *E, *F or *G following RELEASE Q
+
+
+
+ACQUIRE VS I/O 액세스
+----------------------
+
+특정한 (특히 NUMA 가 관련된) 환경 하에서 두개의 CPU 에서 동일한 스핀락으로
+보호되는 두개의 크리티컬 섹션 안의 I/O 액세스는 PCI 브릿지에 겹쳐진 I/O
+액세스로 보일 수 있는데, PCI 브릿지는 캐시 일관성 프로토콜과 합을 맞춰야 할
+의무가 없으므로, 필요한 읽기 메모리 배리어가 요청되지 않기 때문입니다.
+
+예를 들어서:
+
+ CPU 1 CPU 2
+ =============================== ===============================
+ spin_lock(Q)
+ writel(0, ADDR)
+ writel(1, DATA);
+ spin_unlock(Q);
+ spin_lock(Q);
+ writel(4, ADDR);
+ writel(5, DATA);
+ spin_unlock(Q);
+
+는 PCI 브릿지에 다음과 같이 보일 수 있습니다:
+
+ STORE *ADDR = 0, STORE *ADDR = 4, STORE *DATA = 1, STORE *DATA = 5
+
+이렇게 되면 하드웨어의 오동작을 일으킬 수 있습니다.
+
+
+이런 경우엔 잡아둔 스핀락을 내려놓기 전에 mmiowb() 를 수행해야 하는데, 예를
+들면 다음과 같습니다:
+
+ CPU 1 CPU 2
+ =============================== ===============================
+ spin_lock(Q)
+ writel(0, ADDR)
+ writel(1, DATA);
+ mmiowb();
+ spin_unlock(Q);
+ spin_lock(Q);
+ writel(4, ADDR);
+ writel(5, DATA);
+ mmiowb();
+ spin_unlock(Q);
+
+이 코드는 CPU 1 에서 요청된 두개의 스토어가 PCI 브릿지에 CPU 2 에서 요청된
+스토어들보다 먼저 보여짐을 보장합니다.
+
+
+또한, 같은 디바이스에서 스토어를 이어 로드가 수행되면 이 로드는 로드가 수행되기
+전에 스토어가 완료되기를 강제하므로 mmiowb() 의 필요가 없어집니다:
+
+ CPU 1 CPU 2
+ =============================== ===============================
+ spin_lock(Q)
+ writel(0, ADDR)
+ a = readl(DATA);
+ spin_unlock(Q);
+ spin_lock(Q);
+ writel(4, ADDR);
+ b = readl(DATA);
+ spin_unlock(Q);

+
+
+=========================
+메모리 배리어가 필요한 곳
+=========================
+
+설령 SMP 커널을 사용하더라도 싱글 쓰레드로 동작하는 코드는 올바르게 동작하는
+것으로 보여질 것이기 때문에, 평범한 시스템 운영중에 메모리 오퍼레이션 재배치는
+일반적으로 문제가 되지 않습니다. 하지만, 재배치가 문제가 _될 수 있는_ 네가지
+환경이 있습니다:
+
+ (*) 프로세서간 상호 작용.
+
+ (*) 어토믹 오퍼레이션.
+
+ (*) 디바이스 액세스.
+
+ (*) 인터럽트.
+
+
+프로세서간 상호 작용
+--------------------
+
+두개 이상의 프로세서를 가진 시스템이 있다면, 시스템의 두개 이상의 CPU 는 동시에
+같은 데이터에 대한 작업을 할 수 있습니다. 이는 동기화 문제를 일으킬 수 있고,
+이 문제를 해결하는 일반적 방법은 락을 사용하는 것입니다. 하지만, 락은 상당히
+비용이 비싸서 가능하면 락을 사용하지 않고 일을 처리하는 것이 낫습니다. 이런
+경우, 두 CPU 모두에 영향을 끼치는 오퍼레이션들은 오동작을 막기 위해 신중하게
+순서가 맞춰져야 합니다.
+
+예를 들어, R/W 세마포어의 느린 수행경로 (slow path) 를 생각해 봅시다.
+세마포어를 위해 대기를 하는 하나의 프로세스가 자신의 스택 중 일부를 이
+세마포어의 대기 프로세스 리스트에 링크한 채로 있습니다:
+
+ struct rw_semaphore {
+ ...
+ spinlock_t lock;
+ struct list_head waiters;
+ };
+
+ struct rwsem_waiter {
+ struct list_head list;
+ struct task_struct *task;
+ };
+
+특정 대기 상태 프로세스를 깨우기 위해, up_read() 나 up_write() 함수는 다음과
+같은 일을 합니다:
+
+ (1) 다음 대기 상태 프로세스 레코드는 어디있는지 알기 위해 이 대기 상태
+ 프로세스 레코드의 next 포인터를 읽습니다;
+
+ (2) 이 대기 상태 프로세스의 task 구조체로의 포인터를 읽습니다;
+
+ (3) 이 대기 상태 프로세스가 세마포어를 획득했음을 알리기 위해 task
+ 포인터를 초기화 합니다;
+
+ (4) 해당 태스크에 대해 wake_up_process() 를 호출합니다; 그리고
+
+ (5) 해당 대기 상태 프로세스의 task 구조체를 잡고 있던 레퍼런스를 해제합니다.
+
+달리 말하자면, 다음 이벤트 시퀀스를 수행해야 합니다:
+
+ LOAD waiter->list.next;
+ LOAD waiter->task;
+ STORE waiter->task;
+ CALL wakeup
+ RELEASE task
+
+그리고 이 이벤트들이 다른 순서로 수행된다면, 오동작이 일어날 수 있습니다.
+
+한번 세마포어의 대기줄에 들어갔고 세마포어 락을 놓았다면, 해당 대기 프로세스는
+락을 다시는 잡지 않습니다; 대신 자신의 task 포인터가 초기화 되길 기다립니다.
+그 레코드는 대기 프로세스의 스택에 있기 때문에, 리스트의 next 포인터가 읽혀지기
+_전에_ task 포인터가 지워진다면, 다른 CPU 는 해당 대기 프로세스를 시작해 버리고
+up*() 함수가 next 포인터를 읽기 전에 대기 프로세스의 스택을 마구 건드릴 수
+있습니다.
+
+그렇게 되면 위의 이벤트 시퀀스에 어떤 일이 일어나는지 생각해 보죠:
+
+ CPU 1 CPU 2
+ =============================== ===============================
+ down_xxx()
+ Queue waiter
+ Sleep
+ up_yyy()
+ LOAD waiter->task;
+ STORE waiter->task;
+ Woken up by other event
+ <preempt>
+ Resume processing
+ down_xxx() returns
+ call foo()
+ foo() clobbers *waiter
+ </preempt>
+ LOAD waiter->list.next;
+ --- OOPS ---
+
+이 문제는 세마포어 락의 사용으로 해결될 수도 있겠지만, 그렇게 되면 깨어난 후에
+down_xxx() 함수가 불필요하게 스핀락을 또다시 얻어야만 합니다.
+
+이 문제를 해결하는 방법은 범용 SMP 메모리 배리어를 추가하는 겁니다:
+
+ LOAD waiter->list.next;
+ LOAD waiter->task;
+ smp_mb();
+ STORE waiter->task;
+ CALL wakeup
+ RELEASE task
+
+이 경우에, 배리어는 시스템의 나머지 CPU 들에게 모든 배리어 앞의 메모리 액세스가
+배리어 뒤의 메모리 액세스보다 앞서 일어난 것으로 보이게 만듭니다. 배리어 앞의
+메모리 액세스들이 배리어 명령 자체가 완료되는 시점까지 완료된다고는 보장하지
+_않습니다_.
+
+(이게 문제가 되지 않을) 단일 프로세서 시스템에서 smp_mb() 는 실제로는 그저
+컴파일러가 CPU 안에서의 순서를 바꾸거나 하지 않고 주어진 순서대로 명령을
+내리도록 하는 컴파일러 배리어일 뿐입니다. 오직 하나의 CPU 만 있으니, CPU 의
+의존성 순서 로직이 그 외의 모든것을 알아서 처리할 겁니다.
+
+
+어토믹 오퍼레이션
+-----------------
+
+어토믹 오퍼레이션은 기술적으로 프로세서간 상호작용으로 분류되며 그 중 일부는
+전체 메모리 배리어를 내포하고 또 일부는 내포하지 않지만, 커널에서 상당히
+의존적으로 사용하는 기능 중 하나입니다.
+
+메모리의 어떤 상태를 수정하고 해당 상태에 대한 (예전의 또는 최신의) 정보를
+리턴하는 어토믹 오퍼레이션은 모두 SMP-조건적 범용 메모리 배리어(smp_mb())를
+실제 오퍼레이션의 앞과 뒤에 내포합니다. 이런 오퍼레이션은 다음의 것들을
+포함합니다:
+
+ xchg();
+ atomic_xchg(); atomic_long_xchg();
+ atomic_inc_return(); atomic_long_inc_return();
+ atomic_dec_return(); atomic_long_dec_return();
+ atomic_add_return(); atomic_long_add_return();
+ atomic_sub_return(); atomic_long_sub_return();
+ atomic_inc_and_test(); atomic_long_inc_and_test();
+ atomic_dec_and_test(); atomic_long_dec_and_test();
+ atomic_sub_and_test(); atomic_long_sub_and_test();
+ atomic_add_negative(); atomic_long_add_negative();
+ test_and_set_bit();
+ test_and_clear_bit();
+ test_and_change_bit();
+
+ /* exchange 조건이 성공할 때 */
+ cmpxchg();
+ atomic_cmpxchg(); atomic_long_cmpxchg();
+ atomic_add_unless(); atomic_long_add_unless();
+
+이것들은 메모리 배리어 효과가 필요한 ACQUIRE 부류와 RELEASE 부류 오퍼레이션들을
+구현할 때, 그리고 객체 해제를 위해 레퍼런스 카운터를 조정할 때, 암묵적 메모리
+배리어 효과가 필요한 곳 등에 사용됩니다.
+
+
+다음의 오퍼레이션들은 메모리 배리어를 내포하지 _않기_ 때문에 문제가 될 수
+있지만, RELEASE 부류의 오퍼레이션들과 같은 것들을 구현할 때 사용될 수도
+있습니다:
+
+ atomic_set();
+ set_bit();
+ clear_bit();
+ change_bit();
+
+이것들을 사용할 때에는 필요하다면 적절한 (예를 들면 smp_mb__before_atomic()
+같은) 메모리 배리어가 명시적으로 함께 사용되어야 합니다.
+
+
+아래의 것들도 메모리 배리어를 내포하지 _않기_ 때문에, 일부 환경에서는 (예를
+들면 smp_mb__before_atomic() 과 같은) 명시적인 메모리 배리어 사용이 필요합니다.
+
+ atomic_add();
+ atomic_sub();
+ atomic_inc();
+ atomic_dec();
+
+이것들이 통계 생성을 위해 사용된다면, 그리고 통계 데이터 사이에 관계가 존재하지
+않는다면 메모리 배리어는 필요치 않을 겁니다.
+
+객체의 수명을 관리하기 위해 레퍼런스 카운팅 목적으로 사용된다면, 레퍼런스
+카운터는 락으로 보호되는 섹션에서만 조정되거나 호출하는 쪽이 이미 충분한
+레퍼런스를 잡고 있을 것이기 때문에 메모리 배리어는 아마 필요 없을 겁니다.
+
+만약 어떤 락을 구성하기 위해 사용된다면, 락 관련 동작은 일반적으로 작업을 특정
+순서대로 진행해야 하므로 메모리 배리어가 필요할 수 있습니다.
+
+기본적으로, 각 사용처에서는 메모리 배리어가 필요한지 아닌지 충분히 고려해야
+합니다.
+
+아래의 오퍼레이션들은 특별한 락 관련 동작들입니다:
+
+ test_and_set_bit_lock();
+ clear_bit_unlock();
+ __clear_bit_unlock();
+
+이것들은 ACQUIRE 류와 RELEASE 류의 오퍼레이션들을 구현합니다. 락 관련 도구를
+구현할 때에는 이것들을 좀 더 선호하는 편이 나은데, 이것들의 구현은 많은
+아키텍쳐에서 최적화 될 수 있기 때문입니다.
+
+[!] 이런 상황에 사용할 수 있는 특수한 메모리 배리어 도구들이 있습니다만, 일부
+CPU 에서는 사용되는 어토믹 인스트럭션 자체에 메모리 배리어가 내포되어 있어서
+어토믹 오퍼레이션과 메모리 배리어를 함께 사용하는 게 불필요한 일이 될 수
+있는데, 그런 경우에 이 특수 메모리 배리어 도구들은 no-op 이 되어 실질적으로
+아무일도 하지 않습니다.
+
+더 많은 내용을 위해선 Documentation/atomic_ops.txt 를 참고하세요.
+
+
+디바이스 액세스
+---------------
+
+많은 디바이스가 메모리 매핑 기법으로 제어될 수 있는데, 그렇게 제어되는
+디바이스는 CPU 에는 단지 특정 메모리 영역의 집합처럼 보이게 됩니다. 드라이버는
+그런 디바이스를 제어하기 위해 정확히 올바른 순서로 올바른 메모리 액세스를
+만들어야 합니다.
+
+하지만, 액세스들을 재배치 하거나 조합하거나 병합하는게 더 효율적이라 판단하는
+영리한 CPU 나 컴파일러들을 사용하면 드라이버 코드의 조심스럽게 순서 맞춰진
+액세스들이 디바이스에는 요청된 순서대로 도착하지 못하게 할 수 있는 - 디바이스가
+오동작을 하게 할 - 잠재적 문제가 생길 수 있습니다.
+
+리눅스 커널 내부에서, I/O 는 어떻게 액세스들을 적절히 순차적이게 만들 수 있는지
+알고 있는, - inb() 나 writel() 과 같은 - 적절한 액세스 루틴을 통해 이루어져야만
+합니다. 이것들은 대부분의 경우에는 명시적 메모리 배리어 와 함께 사용될 필요가
+없습니다만, 다음의 두가지 상황에서는 명시적 메모리 배리어가 필요할 수 있습니다:
+
+ (1) 일부 시스템에서 I/O 스토어는 모든 CPU 에 일관되게 순서 맞춰지지 않는데,
+ 따라서 _모든_ 일반적인 드라이버들에 락이 사용되어야만 하고 이 크리티컬
+ 섹션을 빠져나오기 전에 mmiowb() 가 꼭 호출되어야 합니다.
+
+ (2) 만약 액세스 함수들이 완화된 메모리 액세스 속성을 갖는 I/O 메모리 윈도우를
+ 사용한다면, 순서를 강제하기 위해선 _mandatory_ 메모리 배리어가 필요합니다.
+
+더 많은 정보를 위해선 Documentation/DocBook/deviceiobook.tmpl 을 참고하십시오.
+
+
+인터럽트
+--------
+
+드라이버는 자신의 인터럽트 서비스 루틴에 의해 인터럽트 당할 수 있기 때문에
+드라이버의 이 두 부분은 서로의 디바이스 제어 또는 액세스 부분과 상호 간섭할 수
+있습니다.
+
+스스로에게 인터럽트 당하는 걸 불가능하게 하고, 드라이버의 크리티컬한
+오퍼레이션들을 모두 인터럽트가 불가능하게 된 영역에 집어넣거나 하는 방법 (락의
+한 형태) 으로 이런 상호 간섭을 - 최소한 부분적으로라도 - 줄일 수 있습니다.
+드라이버의 인터럽트 루틴이 실행 중인 동안, 해당 드라이버의 코어는 같은 CPU 에서
+수행되지 않을 것이며, 현재의 인터럽트가 처리되는 중에는 또다시 인터럽트가
+일어나지 못하도록 되어 있으니 인터럽트 핸들러는 그에 대해서는 락을 잡지 않아도
+됩니다.
+
+하지만, 어드레스 레지스터와 데이터 레지스터를 갖는 이더넷 카드를 다루는
+드라이버를 생각해 봅시다. 만약 이 드라이버의 코어가 인터럽트를 비활성화시킨
+채로 이더넷 카드와 대화하고 드라이버의 인터럽트 핸들러가 호출되었다면:
+
+ LOCAL IRQ DISABLE
+ writew(ADDR, 3);
+ writew(DATA, y);
+ LOCAL IRQ ENABLE
+ <interrupt>
+ writew(ADDR, 4);
+ q = readw(DATA);
+ </interrupt>
+
+만약 순서 규칙이 충분히 완화되어 있다면 데이터 레지스터에의 스토어는 어드레스
+레지스터에 두번째로 행해지는 스토어 뒤에 일어날 수도 있습니다:
+
+ STORE *ADDR = 3, STORE *ADDR = 4, STORE *DATA = y, q = LOAD *DATA
+
+
+만약 순서 규칙이 충분히 완화되어 있고 묵시적으로든 명시적으로든 배리어가
+사용되지 않았다면 인터럽트 비활성화 섹션에서 일어난 액세스가 바깥으로 새어서
+인터럽트 내에서 일어난 액세스와 섞일 수 있다고 - 그리고 그 반대도 - 가정해야만
+합니다.
+
+그런 영역 안에서 일어나는 I/O 액세스들은 엄격한 순서 규칙의 I/O 레지스터에
+묵시적 I/O 배리어를 형성하는 동기적 (synchronous) 로드 오퍼레이션을 포함하기
+때문에 일반적으로는 이런게 문제가 되지 않습니다. 만약 이걸로는 충분치 않다면
+mmiowb() 가 명시적으로 사용될 필요가 있습니다.
+
+
+하나의 인터럽트 루틴과 별도의 CPU 에서 수행중이며 서로 통신을 하는 두 루틴
+사이에도 비슷한 상황이 일어날 수 있습니다. 만약 그런 경우가 발생할 가능성이
+있다면, 순서를 보장하기 위해 인터럽트 비활성화 락이 사용되어져야만 합니다.
+
+
+======================
+커널 I/O 배리어의 효과
+======================
+
+I/O 메모리에 액세스할 때, 드라이버는 적절한 액세스 함수를 사용해야 합니다:
+
+ (*) inX(), outX():
+
+ 이것들은 메모리 공간보다는 I/O 공간에 이야기를 하려는 의도로
+ 만들어졌습니다만, 그건 기본적으로 CPU 마다 다른 컨셉입니다. i386 과
+ x86_64 프로세서들은 특별한 I/O 공간 액세스 사이클과 명령어를 실제로 가지고
+ 있지만, 다른 많은 CPU 들에는 그런 컨셉이 존재하지 않습니다.
+
+ 다른 것들 중에서도 PCI 버스가 I/O 공간 컨셉을 정의하는데, 이는 - i386 과
+ x86_64 같은 CPU 에서 - CPU 의 I/O 공간 컨셉으로 쉽게 매치됩니다. 하지만,
+ 대체할 I/O 공간이 없는 CPU 에서는 CPU 의 메모리 맵의 가상 I/O 공간으로
+ 매핑될 수도 있습니다.
+
+ 이 공간으로의 액세스는 (i386 등에서는) 완전하게 동기화 됩니다만, 중간의
+ (PCI 호스트 브리지와 같은) 브리지들은 이를 완전히 보장하진 않을수도
+ 있습니다.
+
+ 이것들의 상호간의 순서는 완전하게 보장됩니다.
+
+ 다른 타입의 메모리 오퍼레이션, I/O 오퍼레이션에 대한 순서는 완전하게
+ 보장되지는 않습니다.
+
+ (*) readX(), writeX():
+
+ 이것들이 수행 요청되는 CPU 에서 서로에게 완전히 순서가 맞춰지고 독립적으로
+ 수행되는지에 대한 보장 여부는 이들이 액세스 하는 메모리 윈도우에 정의된
+ 특성에 의해 결정됩니다. 예를 들어, 최신의 i386 아키텍쳐 머신에서는 MTRR
+ 레지스터로 이 특성이 조정됩니다.
+
+ 일반적으로는, 프리페치 (prefetch) 가능한 디바이스를 액세스 하는게
+ 아니라면, 이것들은 완전히 순서가 맞춰지고 결합되지 않게 보장될 겁니다.
+
+ 하지만, (PCI 브리지와 같은) 중간의 하드웨어는 자신이 원한다면 집행을
+ 연기시킬 수 있습니다; 스토어 명령을 실제로 하드웨어로 내려보내기(flush)
+ 위해서는 같은 위치로부터 로드를 하는 방법이 있습니다만[*], PCI 의 경우는
+ 같은 디바이스나 환경 구성 영역에서의 로드만으로도 충분할 겁니다.
+
+ [*] 주의! 쓰여진 것과 같은 위치로부터의 로드를 시도하는 것은 오동작을
+ 일으킬 수도 있습니다 - 예로 16650 Rx/Tx 시리얼 레지스터를 생각해
+ 보세요.
+
+ 프리페치 가능한 I/O 메모리가 사용되면, 스토어 명령들이 순서를 지키도록
+ 하기 위해 mmiowb() 배리어가 필요할 수 있습니다.
+
+ PCI 트랜잭션 사이의 상호작용에 대해 더 많은 정보를 위해선 PCI 명세서를
+ 참고하시기 바랍니다.
+
+ (*) readX_relaxed(), writeX_relaxed()
+
+ 이것들은 readX() 와 writeX() 랑 비슷하지만, 더 완화된 메모리 순서 보장을
+ 제공합니다. 구체적으로, 이것들은 일반적 메모리 액세스 (예: DMA 버퍼) 에도
+ LOCK 이나 UNLOCK 오퍼레이션들에도 순서를 보장하지 않습니다. LOCK 이나
+ UNLOCK 오퍼레이션들에 맞춰지는 순서가 필요하다면, mmiowb() 배리어가 사용될
+ 수 있습니다. 같은 주변 장치에의 완화된 액세스끼리는 순서가 지켜짐을 알아
+ 두시기 바랍니다.
+
+ (*) ioreadX(), iowriteX()
+
+ 이것들은 inX()/outX() 나 readX()/writeX() 처럼 실제로 수행하는 액세스의
+ 종류에 따라 적절하게 수행될 것입니다.
+
+
+===================================
+가정되는 가장 완화된 실행 순서 모델
+===================================
+
+컨셉적으로 CPU 는 주어진 프로그램에 대해 프로그램 그 자체에는 인과성 (program
+causality) 을 지키는 것처럼 보이게 하지만 일반적으로는 순서를 거의 지켜주지
+않는다고 가정되어야만 합니다. (i386 이나 x86_64 같은) 일부 CPU 들은 코드
+재배치에 (powerpc 나 frv 와 같은) 다른 것들에 비해 강한 제약을 갖지만, 아키텍쳐
+종속적 코드 이외의 코드에서는 순서에 대한 제약이 가장 완화된 경우 (DEC Alpha)
+를 가정해야 합니다.
+
+이 말은, CPU 에게 주어지는 인스트럭션 스트림 내의 한 인스트럭션이 앞의
+인스트럭션에 종속적이라면 앞의 인스트럭션은 뒤의 종속적 인스트럭션이 실행되기
+전에 완료[*]될 수 있어야 한다는 제약 (달리 말해서, 인과성이 지켜지는 것으로
+보이게 함) 외에는 자신이 원하는 순서대로 - 심지어 병렬적으로도 - 그 스트림을
+실행할 수 있음을 의미합니다
+
+ [*] 일부 인스트럭션은 하나 이상의 영향 - 조건 코드를 바꾼다던지, 레지스터나
+ 메모리를 바꾼다던지 - 을 만들어내며, 다른 인스트럭션은 다른 효과에
+ 종속적일 수 있습니다.
+
+CPU 는 최종적으로 아무 효과도 만들지 않는 인스트럭션 시퀀스는 없애버릴 수도
+있습니다. 예를 들어, 만약 두개의 연속되는 인스트럭션이 둘 다 같은 레지스터에
+직접적인 값 (immediate value) 을 집어넣는다면, 첫번째 인스트럭션은 버려질 수도
+있습니다.
+
+
+비슷하게, 컴파일러 역시 프로그램의 인과성만 지켜준다면 인스트럭션 스트림을
+자신이 보기에 올바르다 생각되는대로 재배치 할 수 있습니다.
+
+
+===============
+CPU 캐시의 영향
+===============
+
+캐시된 메모리 오퍼레이션들이 시스템 전체에 어떻게 인지되는지는 CPU 와 메모리
+사이에 존재하는 캐시들, 그리고 시스템 상태의 일관성을 관리하는 메모리 일관성
+시스템에 상당 부분 영향을 받습니다.
+
+한 CPU 가 시스템의 다른 부분들과 캐시를 통해 상호작용한다면, 메모리 시스템은
+CPU 의 캐시들을 포함해야 하며, CPU 와 CPU 자신의 캐시 사이에서의 동작을 위한
+메모리 배리어를 가져야 합니다. (메모리 배리어는 논리적으로는 다음 그림의
+점선에서 동작합니다):
+
+ <--- CPU ---> : <----------- Memory ----------->
+ :
+ +--------+ +--------+ : +--------+ +-----------+
+ | | | | : | | | | +--------+
+ | CPU | | Memory | : | CPU | | | | |
+ | Core |--->| Access |----->| Cache |<-->| | | |
+ | | | Queue | : | | | |--->| Memory |
+ | | | | : | | | | | |
+ +--------+ +--------+ : +--------+ | | | |
+ : | Cache | +--------+
+ : | Coherency |
+ : | Mechanism | +--------+
+ +--------+ +--------+ : +--------+ | | | |
+ | | | | : | | | | | |
+ | CPU | | Memory | : | CPU | | |--->| Device |
+ | Core |--->| Access |----->| Cache |<-->| | | |
+ | | | Queue | : | | | | | |
+ | | | | : | | | | +--------+
+ +--------+ +--------+ : +--------+ +-----------+
+ :
+ :
+
+특정 로드나 스토어는 해당 오퍼레이션을 요청한 CPU 의 캐시 내에서 동작을 완료할
+수도 있기 때문에 해당 CPU 의 바깥에는 보이지 않을 수 있지만, 다른 CPU 가 관심을
+갖는다면 캐시 일관성 메커니즘이 해당 캐시라인을 해당 CPU 에게 전달하고, 해당
+메모리 영역에 대한 오퍼레이션이 발생할 때마다 그 영향을 전파시키기 때문에, 해당
+오퍼레이션은 메모리에 실제로 액세스를 한것처럼 나타날 것입니다.
+
+CPU 코어는 프로그램의 인과성이 유지된다고만 여겨진다면 인스트럭션들을 어떤
+순서로든 재배치해서 수행할 수 있습니다. 일부 인스트럭션들은 로드나 스토어
+오퍼레이션을 만드는데 이 오퍼레이션들은 이후 수행될 메모리 액세스 큐에 들어가게
+됩니다. 코어는 이 오퍼레이션들을 해당 큐에 어떤 순서로든 원하는대로 넣을 수
+있고, 다른 인스트럭션의 완료를 기다리도록 강제되기 전까지는 수행을 계속합니다.
+
+메모리 배리어가 하는 일은 CPU 쪽에서 메모리 쪽으로 넘어가는 액세스들의 순서,
+그리고 그 액세스의 결과가 시스템의 다른 관찰자들에게 인지되는 순서를 제어하는
+것입니다.
+
+[!] CPU 들은 항상 그들 자신의 로드와 스토어는 프로그램 순서대로 일어난 것으로
+보기 때문에, 주어진 CPU 내에서는 메모리 배리어를 사용할 필요가 _없습니다_.
+
+[!] MMIO 나 다른 디바이스 액세스들은 캐시 시스템을 우회할 수도 있습니다. 우회
+여부는 디바이스가 액세스 되는 메모리 윈도우의 특성에 의해 결정될 수도 있고, CPU
+가 가지고 있을 수 있는 특수한 디바이스 통신 인스트럭션의 사용에 의해서 결정될
+수도 있습니다.
+
+
+캐시 일관성
+-----------
+
+하지만 삶은 앞에서 이야기한 것처럼 단순하지 않습니다: 캐시들은 일관적일 것으로
+기대되지만, 그 일관성이 순서에도 적용될 거라는 보장은 없습니다. 한 CPU 에서
+만들어진 변경 사항은 최종적으로는 시스템의 모든 CPU 에게 보여지게 되지만, 다른
+CPU 들에게도 같은 순서로 보이게 될 거라는 보장은 없다는 뜻입니다.
+
+
+두개의 CPU (1 & 2) 가 달려 있고, 각 CPU 에 두개의 데이터 캐시(CPU 1 은 A/B 를,
+CPU 2 는 C/D 를 갖습니다)가 병렬로 연결되어 있는 시스템을 다룬다고 생각해
+봅시다:
+
+ :
+ : +--------+
+ : +---------+ | |
+ +--------+ : +--->| Cache A |<------->| |
+ | | : | +---------+ | |
+ | CPU 1 |<---+ | |
+ | | : | +---------+ | |
+ +--------+ : +--->| Cache B |<------->| |
+ : +---------+ | |
+ : | Memory |
+ : +---------+ | System |
+ +--------+ : +--->| Cache C |<------->| |
+ | | : | +---------+ | |
+ | CPU 2 |<---+ | |
+ | | : | +---------+ | |
+ +--------+ : +--->| Cache D |<------->| |
+ : +---------+ | |
+ : +--------+
+ :
+
+이 시스템이 다음과 같은 특성을 갖는다 생각해 봅시다:
+
+ (*) 홀수번 캐시라인은 캐시 A, 캐시 C 또는 메모리에 위치할 수 있음;
+
+ (*) 짝수번 캐시라인은 캐시 B, 캐시 D 또는 메모리에 위치할 수 있음;
+
+ (*) CPU 코어가 한개의 캐시에 접근하는 동안, 다른 캐시는 - 더티 캐시라인을
+ 메모리에 내리거나 추측성 로드를 하거나 하기 위해 - 시스템의 다른 부분에
+ 액세스 하기 위해 버스를 사용할 수 있음;
+
+ (*) 각 캐시는 시스템의 나머지 부분들과 일관성을 맞추기 위해 해당 캐시에
+ 적용되어야 할 오퍼레이션들의 큐를 가짐;
+
+ (*) 이 일관성 큐는 캐시에 이미 존재하는 라인에 가해지는 평범한 로드에 의해서는
+ 비워지지 않는데, 큐의 오퍼레이션들이 이 로드의 결과에 영향을 끼칠 수 있다
+ 할지라도 그러함.
+
+이제, 첫번째 CPU 에서 두개의 쓰기 오퍼레이션을 만드는데, 해당 CPU 의 캐시에
+요청된 순서로 오퍼레이션이 도달됨을 보장하기 위해 두 오퍼레이션 사이에 쓰기
+배리어를 사용하는 상황을 상상해 봅시다:
+
+ CPU 1 CPU 2 COMMENT
+ =============== =============== =======================================
+ u == 0, v == 1 and p == &u, q == &u
+ v = 2;
+ smp_wmb(); v 의 변경이 p 의 변경 전에 보일 것을
+ 분명히 함
+ <A:modify v=2> v 는 이제 캐시 A 에 독점적으로 존재함
+ p = &v;
+ <B:modify p=&v> p 는 이제 캐시 B 에 독점적으로 존재함
+
+여기서의 쓰기 메모리 배리어는 CPU 1 의 캐시가 올바른 순서로 업데이트 된 것으로
+시스템의 다른 CPU 들이 인지하게 만듭니다. 하지만, 이제 두번째 CPU 가 그 값들을
+읽으려 하는 상황을 생각해 봅시다:
+
+ CPU 1 CPU 2 COMMENT
+ =============== =============== =======================================
+ ...
+ q = p;
+ x = *q;
+
+위의 두개의 읽기 오퍼레이션은 예상된 순서로 일어나지 못할 수 있는데, 두번째 CPU
+의 한 캐시에 다른 캐시 이벤트가 발생해 v 를 담고 있는 캐시라인의 해당 캐시에의
+업데이트가 지연되는 사이, p 를 담고 있는 캐시라인은 두번째 CPU 의 다른 캐시에
+업데이트 되어버렸을 수 있기 때문입니다.
+
+ CPU 1 CPU 2 COMMENT
+ =============== =============== =======================================
+ u == 0, v == 1 and p == &u, q == &u
+ v = 2;
+ smp_wmb();
+ <A:modify v=2> <C:busy>
+ <C:queue v=2>
+ p = &v; q = p;
+ <D:request p>
+ <B:modify p=&v> <D:commit p=&v>
+ <D:read p>
+ x = *q;
+ <C:read *q> 캐시에 업데이트 되기 전의 v 를 읽음
+ <C:unbusy>
+ <C:commit v=2>
+
+기본적으로, 두개의 캐시라인 모두 CPU 2 에 최종적으로는 업데이트 될 것이지만,
+별도의 개입 없이는, 업데이트의 순서가 CPU 1 에서 만들어진 순서와 동일할
+것이라는 보장이 없습니다.
+
+
+여기에 개입하기 위해선, 데이터 의존성 배리어나 읽기 배리어를 로드 오퍼레이션들
+사이에 넣어야 합니다. 이렇게 함으로써 캐시가 다음 요청을 처리하기 전에 일관성
+큐를 처리하도록 강제하게 됩니다.

+
+이런 부류의 문제는 DEC Alpha 계열 프로세서들에서 발견될 수 있는데, 이들은
+데이터 버스를 좀 더 잘 사용해 성능을 개선할 수 있는, 분할된 캐시를 가지고 있기
+때문입니다. 대부분의 CPU 는 하나의 읽기 오퍼레이션의 메모리 액세스가 다른 읽기
+오퍼레이션에 의존적이라면 데이터 의존성 배리어를 내포시킵니다만, 모두가 그런건
+아니기 때문에 이점에 의존해선 안됩니다.
+
+다른 CPU 들도 분할된 캐시를 가지고 있을 수 있지만, 그런 CPU 들은 평범한 메모리
+액세스를 위해서도 이 분할된 캐시들 사이의 조정을 해야만 합니다. Alpha 는 가장
+약한 메모리 순서 시맨틱 (semantic) 을 선택함으로써 메모리 배리어가 명시적으로
+사용되지 않았을 때에는 그런 조정이 필요하지 않게 했습니다.
+
+
+캐시 일관성 VS DMA
+------------------
+
+모든 시스템이 DMA 를 하는 디바이스에 대해서까지 캐시 일관성을 유지하지는
+않습니다. 그런 경우, DMA 를 시도하는 디바이스는 RAM 으로부터 잘못된 데이터를
+읽을 수 있는데, 더티 캐시 라인이 CPU 의 캐시에 머무르고 있고, 바뀐 값이 아직
+RAM 에 써지지 않았을 수 있기 때문입니다. 이 문제를 해결하기 위해선, 커널의
+적절한 부분에서 각 CPU 캐시의 문제되는 비트들을 플러시 (flush) 시켜야만 합니다
+(그리고 그것들을 무효화 - invalidation - 시킬 수도 있겠죠).
+
+또한, 디바이스에 의해 RAM 에 DMA 로 쓰여진 값은 디바이스가 쓰기를 완료한 후에
+CPU 의 캐시에서 RAM 으로 쓰여지는 더티 캐시 라인에 의해 덮어써질 수도 있고, CPU
+의 캐시에 존재하는 캐시 라인이 해당 캐시에서 삭제되고 다시 값을 읽어들이기
+전까지는 RAM 이 업데이트 되었다는 사실 자체가 숨겨져 버릴 수도 있습니다. 이
+문제를 해결하기 위해선, 커널의 적절한 부분에서 각 CPU 의 캐시 안의 문제가 되는
+비트들을 무효화 시켜야 합니다.
+
+캐시 관리에 대한 더 많은 정보를 위해선 Documentation/cachetlb.txt 를
+참고하세요.
+
+
+캐시 일관성 VS MMIO
+-------------------
+
+Memory mapped I/O 는 일반적으로 CPU 의 메모리 공간 내의 한 윈도우의 특정 부분
+내의 메모리 지역에 이루어지는데, 이 윈도우는 일반적인, RAM 으로 향하는
+윈도우와는 다른 특성을 갖습니다.
+
+그런 특성 가운데 하나는, 일반적으로 그런 액세스는 캐시를 완전히 우회하고
+디바이스 버스로 곧바로 향한다는 것입니다. 이 말은 MMIO 액세스는 먼저
+시작되어서 캐시에서 완료된 메모리 액세스를 추월할 수 있다는 뜻입니다. 이런
+경우엔 메모리 배리어만으로는 충분치 않고, 만약 캐시된 메모리 쓰기 오퍼레이션과
+MMIO 액세스가 어떤 방식으로든 의존적이라면 해당 캐시는 두 오퍼레이션 사이에
+비워져(flush)야만 합니다.
+
+
+======================
+CPU 들이 저지르는 일들
+======================
+
+프로그래머는 CPU 가 메모리 오퍼레이션들을 정확히 요청한대로 수행해 줄 것이라고
+생각하는데, 예를 들어 다음과 같은 코드를 CPU 에게 넘긴다면:
+
+ a = READ_ONCE(*A);
+ WRITE_ONCE(*B, b);
+ c = READ_ONCE(*C);
+ d = READ_ONCE(*D);
+ WRITE_ONCE(*E, e);
+
+CPU 는 다음 인스트럭션을 처리하기 전에 현재의 인스트럭션을 위한 메모리
+오퍼레이션을 완료할 것이라 생각하고, 따라서 시스템 외부에서 관찰하기에도 정해진
+순서대로 오퍼레이션이 수행될 것으로 예상합니다:
+
+ LOAD *A, STORE *B, LOAD *C, LOAD *D, STORE *E.
+
+
+당연하지만, 실제로는 훨씬 엉망입니다. 많은 CPU 와 컴파일러에서 앞의 가정은
+성립하지 못하는데 그 이유는 다음과 같습니다:
+
+ (*) 로드 오퍼레이션들은 실행을 계속 해나가기 위해 곧바로 완료될 필요가 있는
+ 경우가 많은 반면, 스토어 오퍼레이션들은 종종 별다른 문제 없이 유예될 수
+ 있습니다;
+
+ (*) 로드 오퍼레이션들은 예측적으로 수행될 수 있으며, 필요없는 로드였다고
+ 증명된 예측적 로드의 결과는 버려집니다;
+
+ (*) 로드 오퍼레이션들은 예측적으로 수행될 수 있으므로, 예상된 이벤트의
+ 시퀀스와 다른 시간에 로드가 이뤄질 수 있습니다;
+
+ (*) 메모리 액세스 순서는 CPU 버스와 캐시를 좀 더 잘 사용할 수 있도록 재배치
+ 될 수 있습니다;
+
+ (*) 로드와 스토어는 인접한 위치에의 액세스들을 일괄적으로 처리할 수 있는
+ 메모리나 I/O 하드웨어 (메모리와 PCI 디바이스 둘 다 이게 가능할 수
+ 있습니다) 에 대해 요청되는 경우, 개별 오퍼레이션을 위한 트랜잭션 설정
+ 비용을 아끼기 위해 조합되어 실행될 수 있습니다; 그리고
+
+ (*) 해당 CPU 의 데이터 캐시가 순서에 영향을 끼칠 수도 있고, 캐시 일관성
+ 메커니즘이 - 스토어가 실제로 캐시에 도달한다면 - 이 문제를 완화시킬 수는
+ 있지만 이 일관성 관리가 다른 CPU 들에도 같은 순서로 전달된다는 보장은
+ 없습니다.
+
+따라서, 앞의 코드에 대해 다른 CPU 가 보는 결과는 다음과 같을 수 있습니다:
+
+ LOAD *A, ..., LOAD {*C,*D}, STORE *E, STORE *B
+
+ ("LOAD {*C,*D}" 는 조합된 로드입니다)
+
+
+하지만, CPU 는 스스로는 일관적일 것을 보장합니다: CPU _자신_ 의 액세스들은
+자신에게는 메모리 배리어가 없음에도 불구하고 정확히 순서 세워진 것으로 보여질
+것입니다. 예를 들어 다음의 코드가 주어졌다면:
+
+ U = READ_ONCE(*A);
+ WRITE_ONCE(*A, V);
+ WRITE_ONCE(*A, W);
+ X = READ_ONCE(*A);
+ WRITE_ONCE(*A, Y);
+ Z = READ_ONCE(*A);
+
+그리고 외부의 영향에 의한 간섭이 없다고 가정하면, 최종 결과는 다음과 같이
+나타날 것이라고 예상될 수 있습니다:
+
+ U == *A 의 최초 값
+ X == W
+ Z == Y
+ *A == Y
+
+앞의 코드는 CPU 가 다음의 메모리 액세스 시퀀스를 만들도록 할겁니다:
+
+ U=LOAD *A, STORE *A=V, STORE *A=W, X=LOAD *A, STORE *A=Y, Z=LOAD *A
+
+하지만, 별다른 개입이 없고 프로그램의 시야에 이 세상이 여전히 일관적이라고
+보인다는 보장만 지켜진다면 이 시퀀스는 어떤 조합으로든 재구성될 수 있으며, 각
+액세스들은 합쳐지거나 버려질 수 있습니다. 일부 아키텍쳐에서 CPU 는 같은 위치에
+대한 연속적인 로드 오퍼레이션들을 재배치 할 수 있기 때문에 앞의 예에서의
+READ_ONCE() 와 WRITE_ONCE() 는 반드시 존재해야 함을 알아두세요. 그런 종류의
+아키텍쳐에서 READ_ONCE() 와 WRITE_ONCE() 는 이 문제를 막기 위해 필요한 일을
+뭐가 됐든지 하게 되는데, 예를 들어 Itanium 에서는 READ_ONCE() 와 WRITE_ONCE()
+가 사용하는 volatile 캐스팅은 GCC 가 그런 재배치를 방지하는 특수 인스트럭션인
+ld.acq 와 stl.rel 인스트럭션을 각각 만들어 내도록 합니다.
+
+컴파일러 역시 이 시퀀스의 액세스들을 CPU 가 보기도 전에 합치거나 버리거나 뒤로
+미뤄버릴 수 있습니다.
+
+예를 들어:
+
+ *A = V;
+ *A = W;
+
+는 다음과 같이 변형될 수 있습니다:
+
+ *A = W;
+
+따라서, 쓰기 배리어나 WRITE_ONCE() 가 없다면 *A 로의 V 값의 저장의 효과는
+사라진다고 가정될 수 있습니다. 비슷하게:
+
+ *A = Y;
+ Z = *A;
+
+는, 메모리 배리어나 READ_ONCE() 와 WRITE_ONCE() 없이는 다음과 같이 변형될 수
+있습니다:
+
+ *A = Y;
+ Z = Y;
+
+그리고 이 LOAD 오퍼레이션은 CPU 바깥에는 아예 보이지 않습니다.
+
+
+그리고, ALPHA 가 있다
+---------------------
+
+DEC Alpha CPU 는 가장 완화된 메모리 순서의 CPU 중 하나입니다. 뿐만 아니라,
+Alpha CPU 의 일부 버전은 분할된 데이터 캐시를 가지고 있어서, 의미적으로
+관계되어 있는 두개의 캐시 라인이 서로 다른 시간에 업데이트 되는게 가능합니다.
+이게 데이터 의존성 배리어가 정말 필요해지는 부분인데, 데이터 의존성 배리어는
+메모리 일관성 시스템과 함께 두개의 캐시를 동기화 시켜서, 포인터 변경과 새로운
+데이터의 발견을 올바른 순서로 일어나게 하기 때문입니다.
+
+리눅스 커널의 메모리 배리어 모델은 Alpha 에 기초해서 정의되었습니다.
+
+위의 "캐시 일관성" 서브섹션을 참고하세요.
+
+
+가상 머신 게스트
+----------------
+
+가상 머신에서 동작하는 게스트들은 게스트 자체는 SMP 지원 없이 컴파일 되었다
+해도 SMP 영향을 받을 수 있습니다. 이건 UP 커널을 사용하면서 SMP 호스트와
+결부되어 발생하는 부작용입니다. 이 경우에는 mandatory 배리어를 사용해서 문제를
+해결할 수 있겠지만 그런 해결은 대부분의 경우 최적의 해결책이 아닙니다.
+
+이 문제를 완벽하게 해결하기 위해, 로우 레벨의 virt_mb() 등의 매크로를 사용할 수
+있습니다. 이것들은 SMP 가 활성화 되어 있다면 smp_mb() 등과 동일한 효과를
+갖습니다만, SMP 와 SMP 아닌 시스템 모두에 대해 동일한 코드를 만들어냅니다.
+예를 들어, 가상 머신 게스트들은 (SMP 일 수 있는) 호스트와 동기화를 할 때에는
+smp_mb() 가 아니라 virt_mb() 를 사용해야 합니다.
+
+이것들은 smp_mb() 류의 것들과 모든 부분에서 동일하며, 특히, MMIO 의 영향에
+대해서는 간여하지 않습니다: MMIO 의 영향을 제어하려면, mandatory 배리어를
+사용하시기 바랍니다.
+
+

+사용 예

+
+순환식 버퍼
+-----------
+
+메모리 배리어는 순환식 버퍼를 생성자(producer)와 소비자(consumer) 사이의
+동기화에 락을 사용하지 않고 구현하는데에 사용될 수 있습니다. 더 자세한 내용을

+USB port LED trigger
+====================
+
+This LED trigger can be used for signalling to the user a presence of USB device
+in a given port. It simply turns on LED when device appears and turns it off
+when it disappears.
+
+It requires selecting USB ports that should be observed. All available ones are
+listed as separated entries in a "ports" subdirectory. Selecting is handled by
+echoing "1" to a chosen port.
+
+Please note that this trigger allows selecting multiple USB ports for a single
+LED. This can be useful in two cases:
+
+1) Device with single USB LED and few physical ports
+
+In such a case LED will be turned on as long as there is at least one connected
+USB device.
+
+2) Device with a physical port handled by few controllers
+
+Some devices may have one controller per PHY standard. E.g. USB 3.0 physical
+port may be handled by ohci-platform, ehci-platform and xhci-hcd. If there is
+only one LED user will most likely want to assign ports from all 3 hubs.
+
+
+This trigger can be activated from user space on led class devices as shown

-lglock - local/global locks for mostly local access patterns
-------------------------------------------------------------
-
-Origin: Nick Piggin's VFS scalability series introduced during
- 2.6.35++ [1] [2]
-Location: kernel/locking/lglock.c
- include/linux/lglock.h
-Users: currently only the VFS and stop_machine related code
-
-Design Goal:
-------------
-
-Improve scalability of globally used large data sets that are
-distributed over all CPUs as per_cpu elements.
-
-To manage global data structures that are partitioned over all CPUs
-as per_cpu elements but can be mostly handled by CPU local actions
-lglock will be used where the majority of accesses are cpu local
-reading and occasional cpu local writing with very infrequent
-global write access.
-
-
-* deal with things locally whenever possible
- - very fast access to the local per_cpu data
- - reasonably fast access to specific per_cpu data on a different
- CPU
-* while making global action possible when needed
- - by expensive access to all CPUs locks - effectively
- resulting in a globally visible critical section.
-
-Design:
--------
-
-Basically it is an array of per_cpu spinlocks with the
-lg_local_lock/unlock accessing the local CPUs lock object and the
-lg_local_lock_cpu/unlock_cpu accessing a remote CPUs lock object
-the lg_local_lock has to disable preemption as migration protection so
-that the reference to the local CPUs lock does not go out of scope.
-Due to the lg_local_lock/unlock only touching cpu-local resources it
-is fast. Taking the local lock on a different CPU will be more
-expensive but still relatively cheap.
-
-One can relax the migration constraints by acquiring the current
-CPUs lock with lg_local_lock_cpu, remember the cpu, and release that
-lock at the end of the critical section even if migrated. This should
-give most of the performance benefits without inhibiting migration
-though needs careful considerations for nesting of lglocks and
-consideration of deadlocks with lg_global_lock.
-
-The lg_global_lock/unlock locks all underlying spinlocks of all
-possible CPUs (including those off-line). The preemption disable/enable
-are needed in the non-RT kernels to prevent deadlocks like:
-
- on cpu 1
-
- task A task B
- lg_global_lock
- got cpu 0 lock
- <<<< preempt <<<<
- lg_local_lock_cpu for cpu 0
- spin on cpu 0 lock
-
-On -RT this deadlock scenario is resolved by the arch_spin_locks in the
-lglocks being replaced by rt_mutexes which resolve the above deadlock
-by boosting the lock-holder.
-
-
-Implementation:
----------------
-
-The initial lglock implementation from Nick Piggin used some complex
-macros to generate the lglock/brlock in lglock.h - they were later
-turned into a set of functions by Andi Kleen [7]. The change to functions
-was motivated by the presence of multiple lock users and also by them
-being easier to maintain than the generating macros. This change to
-functions is also the basis to eliminated the restriction of not
-being initializeable in kernel modules (the remaining problem is that
-locks are not explicitly initialized - see lockdep-design.txt)
-
-Declaration and initialization:
--------------------------------
-
- #include <linux/lglock.h>
-
- DEFINE_LGLOCK(name)
- or:
- DEFINE_STATIC_LGLOCK(name);
-
- lg_lock_init(&name, "lockdep_name_string");
-
- on UP this is mapped to DEFINE_SPINLOCK(name) in both cases, note
- also that as of 3.18-rc6 all declaration in use are of the _STATIC_
- variant (and it seems that the non-static was never in use).
- lg_lock_init is initializing the lockdep map only.
-
-Usage:
-------
-
-From the locking semantics it is a spinlock. It could be called a
-locality aware spinlock. lg_local_* behaves like a per_cpu
-spinlock and lg_global_* like a global spinlock.
-No surprises in the API.
-
- lg_local_lock(*lglock);
- access to protected per_cpu object on this CPU
- lg_local_unlock(*lglock);
-
- lg_local_lock_cpu(*lglock, cpu);
- access to protected per_cpu object on other CPU cpu
- lg_local_unlock_cpu(*lglock, cpu);
-
- lg_global_lock(*lglock);
- access all protected per_cpu objects on all CPUs
- lg_global_unlock(*lglock);
-
- There are no _trylock variants of the lglocks.
-
-Note that the lg_global_lock/unlock has to iterate over all possible
-CPUs rather than the actually present CPUs or a CPU could go off-line
-with a held lock [4] and that makes it very expensive. A discussion on
-these issues can be found at [5]
-
-Constraints:
-------------
-
- * currently the declaration of lglocks in kernel modules is not
- possible, though this should be doable with little change.
- * lglocks are not recursive.
- * suitable for code that can do most operations on the CPU local
- data and will very rarely need the global lock
- * lg_global_lock/unlock is *very* expensive and does not scale
- * on UP systems all lg_* primitives are simply spinlocks
- * in PREEMPT_RT the spinlock becomes an rt-mutex and can sleep but
- does not change the tasks state while sleeping [6].
- * in PREEMPT_RT the preempt_disable/enable in lg_local_lock/unlock
- is downgraded to a migrate_disable/enable, the other
- preempt_disable/enable are downgraded to barriers [6].
- The deadlock noted for non-RT above is resolved due to rt_mutexes
- boosting the lock-holder in this case which arch_spin_locks do
- not do.
-
-lglocks were designed for very specific problems in the VFS and probably
-only are the right answer in these corner cases. Any new user that looks
-at lglocks probably wants to look at the seqlock and RCU alternatives as
-her first choice. There are also efforts to resolve the RCU issues that
-currently prevent using RCU in place of view remaining lglocks.
-
-Note on brlock history:
------------------------
-
-The 'Big Reader' read-write spinlocks were originally introduced by
-Ingo Molnar in 2000 (2.4/2.5 kernel series) and removed in 2003. They
-later were introduced by the VFS scalability patch set in 2.6 series
-again as the "big reader lock" brlock [2] variant of lglock which has
-been replaced by seqlock primitives or by RCU based primitives in the
-3.13 kernel series as was suggested in [3] in 2003. The brlock was
-entirely removed in the 3.13 kernel series.

+ When a SCHED_DEADLINE task calls sched_yield(), it gives up its

-Using sparse for typechecking
-~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
-
-"__bitwise" is a type attribute, so you have to do something like this:
-
- typedef int __bitwise pm_request_t;
-
- enum pm_request {
- PM_SUSPEND = (__force pm_request_t) 1,
- PM_RESUME = (__force pm_request_t) 2
- };
-
-which makes PM_SUSPEND and PM_RESUME "bitwise" integers (the "__force" is
-there because sparse will complain about casting to/from a bitwise type,
-but in this case we really _do_ want to force the conversion). And because
-the enum values are all the same type, now "enum pm_request" will be that
-type too.
-
-And with gcc, all the __bitwise/__force stuff goes away, and it all ends
-up looking just like integers to gcc.
-
-Quite frankly, you don't need the enum there. The above all really just
-boils down to one special "int __bitwise" type.
-
-So the simpler way is to just do
-
- typedef int __bitwise pm_request_t;
-
- #define PM_SUSPEND ((__force pm_request_t) 1)
- #define PM_RESUME ((__force pm_request_t) 2)
-
-and you now have all the infrastructure needed for strict typechecking.
-
-One small note: the constant integer "0" is special. You can use a
-constant zero as a bitwise integer type without sparse ever complaining.
-This is because "bitwise" (as the name implies) was designed for making
-sure that bitwise types don't get mixed up (little-endian vs big-endian
-vs cpu-endian vs whatever), and there the constant "0" really _is_
-special.
-
-__bitwise__ - to be used for relatively compact stuff (gfp_t, etc.) that
-is mostly warning-free and is supposed to stay that way. Warnings will
-be generated without __CHECK_ENDIAN__.
-
-__bitwise - noisy stuff; in particular, __le*/__be* are that. We really
-don't want to drown in noise unless we'd explicitly asked for it.
-
-Using sparse for lock checking
-~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
-
-The following macros are undefined for gcc and defined during a sparse
-run to use the "context" tracking feature of sparse, applied to
-locking. These annotations tell sparse when a lock is held, with
-regard to the annotated function's entry and exit.
-
-__must_hold - The specified lock is held on function entry and exit.
-
-__acquires - The specified lock is held on function exit, but not entry.
-
-__releases - The specified lock is held on function entry, but not exit.
-
-If the function enters and exits without the lock held, acquiring and
-releasing the lock inside the function in a balanced way, no
-annotation is needed. The tree annotations above are for cases where
-sparse would otherwise report a context imbalance.
-
-Getting sparse
-~~~~~~~~~~~~~~
-
-You can get latest released versions from the Sparse homepage at
-https://sparse.wiki.kernel.org/index.php/Main_Page
-
-Alternatively, you can get snapshots of the latest development version
-of sparse using git to clone..
-
- git://git.kernel.org/pub/scm/devel/sparse/sparse.git
-
-DaveJ has hourly generated tarballs of the git tree available at..
-
- http://www.codemonkey.org.uk/projects/git-snapshots/sparse/
-
-
-Once you have it, just do
-
- make
- make install
-
-as a regular user, and it will install sparse in your ~/bin directory.
-
-Using sparse
-~~~~~~~~~~~~
-
-Do a kernel make with "make C=1" to run sparse on all the C files that get
-recompiled, or use "make C=2" to run sparse on the files whether they need to
-be recompiled or not. The latter is a fast way to check the whole tree if you
-have already built it.
-
-The optional make variable CF can be used to pass arguments to sparse. The
-build system passes -Wbitwise to sparse automatically. To perform endianness
-checks, you may define __CHECK_ENDIAN__:
-
- make C=2 CF="-D__CHECK_ENDIAN__"
-
-These checks are disabled by default as they generate a host of warnings.

+ List of customizations:
+
+ * Moved the *duplicate C object description* warnings for function

+ the config values for ``nitpick`` and ``nitpick_ignore``.
+
+ * Add option 'name' to the "c:function:" directive. With option 'name' the

+ .. c:function:: int ioctl( int fd, int request )
+ :name: VIDIOC_LOG_STATUS
+
+ The func-name (e.g. ioctl) remains in the output but the ref-name changed

+
+ * :c:func:`VIDIOC_LOG_STATUS` or

+
+The primary purpose of these limits is to stop programs that

+before the malfunction becomes a system wide problem. It is the
+intention that the defaults of these limits are set high enough that
+no program in normal operation should run into these limits.
+
+The creation of per user per user namespace objects are charged to
+the user in the user namespace who created the object and
+verified to be below the per user limit in that user namespace.
+
+The creation of objects is also charged to all of the users
+who created user namespaces the creation of the object happens
+in (user namespaces can be nested) and verified to be below the per user
+limits in the user namespaces of those users.
+
+This recursive counting of created objects ensures that creating a
+user namespace does not allow a user to escape their current limits.

+Introduction:
+-------------
+
+The tracer hwlat_detector is a special purpose tracer that is used to
+detect large system latencies induced by the behavior of certain underlying
+hardware or firmware, independent of Linux itself. The code was developed
+originally to detect SMIs (System Management Interrupts) on x86 systems,
+however there is nothing x86 specific about this patchset. It was
+originally written for use by the "RT" patch since the Real Time
+kernel is highly latency sensitive.
+
+SMIs are not serviced by the Linux kernel, which means that it does not
+even know that they are occuring. SMIs are instead set up by BIOS code
+and are serviced by BIOS code, usually for "critical" events such as
+management of thermal sensors and fans. Sometimes though, SMIs are used for
+other tasks and those tasks can spend an inordinate amount of time in the
+handler (sometimes measured in milliseconds). Obviously this is a problem if
+you are trying to keep event service latencies down in the microsecond range.
+
+The hardware latency detector works by hogging one of the cpus for configurable
+amounts of time (with interrupts disabled), polling the CPU Time Stamp Counter
+for some period, then looking for gaps in the TSC data. Any gap indicates a
+time when the polling was interrupted and since the interrupts are disabled,
+the only thing that could do that would be an SMI or other hardware hiccup
+(or an NMI, but those can be tracked).
+
+Note that the hwlat detector should *NEVER* be used in a production environment.
+It is intended to be run manually to determine if the hardware platform has a
+problem with long system firmware service routines.
+
+Usage:
+------
+
+Write the ASCII text "hwlat" into the current_tracer file of the tracing system
+(mounted at /sys/kernel/tracing or /sys/kernel/tracing). It is possible to
+redefine the threshold in microseconds (us) above which latency spikes will
+be taken into account.
+
+Example:
+
+ # echo hwlat > /sys/kernel/tracing/current_tracer
+ # echo 100 > /sys/kernel/tracing/tracing_thresh
+
+The /sys/kernel/tracing/hwlat_detector interface contains the following files:
+
+width - time period to sample with CPUs held (usecs)
+ must be less than the total window size (enforced)
+window - total period of sampling, width being inside (usecs)
+
+By default the width is set to 500,000 and window to 1,000,000, meaning that
+for every 1,000,000 usecs (1s) the hwlat detector will spin for 500,000 usecs
+(0.5s). If tracing_thresh contains zero when hwlat tracer is enabled, it will
+change to a default of 10 usecs. If any latencies that exceed the threshold is
+observed then the data will be written to the tracing ring buffer.
+
+The minimum sleep time between periods is 1 millisecond. Even if width
+is less than 1 millisecond apart from window, to allow the system to not
+be totally starved.
+
+If tracing_thresh was zero when hwlat detector was started, it will be set
+back to zero if another tracer is loaded. Note, the last value in
+tracing_thresh that hwlat detector had will be saved and this value will
+be restored in tracing_thresh if it is still zero when hwlat detector is
+started again.
+
+The following tracing directory files are used by the hwlat_detector:
+
+in /sys/kernel/tracing:
+
+ tracing_threshold - minimum latency value to be considered (usecs)
+ tracing_max_latency - maximum hardware latency actually observed (usecs)
+ tracing_cpumask - the CPUs to move the hwlat thread across
+ hwlat_detector/width - specified amount of time to spin within window (usecs)
+ hwlat_detector/window - amount of time between (width) runs (usecs)
+
+The hwlat detector's kernel thread will migrate across each CPU specified in
+tracing_cpumask between each window. To limit the migration, either modify
+tracing_cpumask, or modify the hwlat kernel thread (named [hwlatd]) CPU
+affinity directly, and the migration will stop.

-that may cause UB. If check fails (i.e. UB detected) __ubsan_handle_*
-function called to print error message.
-
-GCC has that feature since 4.9.x [1] (see -fsanitize=undefined option and
-its suboptions). GCC 5.x has more checkers implemented [2].

-Usage
------
-
-To enable UBSAN configure kernel with:
-
- CONFIG_UBSAN=y
-
-and to check the entire kernel:
-
- CONFIG_UBSAN_SANITIZE_ALL=y
-
-To enable instrumentation for specific files or directories, add a line
-similar to the following to the respective kernel Makefile:
-
- For a single file (e.g. main.o):
- UBSAN_SANITIZE_main.o := y
-
- For all files in one directory:
- UBSAN_SANITIZE := y
-
-To exclude files from being instrumented even if
-CONFIG_UBSAN_SANITIZE_ALL=y, use:
-
- UBSAN_SANITIZE_main.o := n
- and:
- UBSAN_SANITIZE := n
-
-Detection of unaligned accesses controlled through the separate option -
-CONFIG_UBSAN_ALIGNMENT. It's off by default on architectures that support
-unaligned accesses (CONFIG_HAVE_EFFICIENT_UNALIGNED_ACCESS=y). One could
-still enable it in config, just note that it will produce a lot of UBSAN
-reports.

+ARM Virtual Generic Interrupt Controller v3 and later (VGICv3)
+==============================================================

+Device types supported:

+
+Only one VGIC instance may be instantiated through this API. The created VGIC

+ KVM_DEV_ARM_VGIC_GRP_DIST_REGS
+ KVM_DEV_ARM_VGIC_GRP_REDIST_REGS
+ Attributes:
+ The attr field of kvm_device_attr encodes two values:
+ bits: | 63 .... 32 | 31 .... 0 |
+ values: | mpidr | offset |
+
+ All distributor regs are (rw, 32-bit) and kvm_device_attr.addr points to a
+ __u32 value. 64-bit registers must be accessed by separately accessing the
+ lower and higher word.
+
+ Writes to read-only registers are ignored by the kernel.
+
+ KVM_DEV_ARM_VGIC_GRP_DIST_REGS accesses the main distributor registers.
+ KVM_DEV_ARM_VGIC_GRP_REDIST_REGS accesses the redistributor of the CPU
+ specified by the mpidr.
+
+ The offset is relative to the "[Re]Distributor base address" as defined
+ in the GICv3/4 specs. Getting or setting such a register has the same
+ effect as reading or writing the register on real hardware, except for the
+ following registers: GICD_STATUSR, GICR_STATUSR, GICD_ISPENDR,
+ GICR_ISPENDR0, GICD_ICPENDR, and GICR_ICPENDR0. These registers behave
+ differently when accessed via this interface compared to their
+ architecturally defined behavior to allow software a full view of the
+ VGIC's internal state.
+
+ The mpidr field is used to specify which
+ redistributor is accessed. The mpidr is ignored for the distributor.
+
+ The mpidr encoding is based on the affinity information in the
+ architecture defined MPIDR, and the field is encoded as follows:
+ | 63 .... 56 | 55 .... 48 | 47 .... 40 | 39 .... 32 |
+ | Aff3 | Aff2 | Aff1 | Aff0 |
+
+ Note that distributor fields are not banked, but return the same value
+ regardless of the mpidr used to access the register.
+
+ The GICD_STATUSR and GICR_STATUSR registers are architecturally defined such
+ that a write of a clear bit has no effect, whereas a write with a set bit
+ clears that value. To allow userspace to freely set the values of these two
+ registers, setting the attributes with the register offsets for these two
+ registers simply sets the non-reserved bits to the value written.
+
+
+ Accesses (reads and writes) to the GICD_ISPENDR register region and
+ GICR_ISPENDR0 registers get/set the value of the latched pending state for
+ the interrupts.
+
+ This is identical to the value returned by a guest read from ISPENDR for an
+ edge triggered interrupt, but may differ for level triggered interrupts.
+ For edge triggered interrupts, once an interrupt becomes pending (whether
+ because of an edge detected on the input line or because of a guest write
+ to ISPENDR) this state is "latched", and only cleared when either the
+ interrupt is activated or when the guest writes to ICPENDR. A level
+ triggered interrupt may be pending either because the level input is held
+ high by a device, or because of a guest write to the ISPENDR register. Only
+ ISPENDR writes are latched; if the device lowers the line level then the
+ interrupt is no longer pending unless the guest also wrote to ISPENDR, and
+ conversely writes to ICPENDR or activations of the interrupt do not clear
+ the pending status if the line level is still being held high. (These
+ rules are documented in the GICv3 specification descriptions of the ICPENDR
+ and ISPENDR registers.) For a level triggered interrupt the value accessed
+ here is that of the latch which is set by ISPENDR and cleared by ICPENDR or
+ interrupt activation, whereas the value returned by a guest read from
+ ISPENDR is the logical OR of the latch value and the input line level.
+
+ Raw access to the latch state is provided to userspace so that it can save
+ and restore the entire GIC internal state (which is defined by the
+ combination of the current input line level and the latch state, and cannot
+ be deduced from purely the line level and the value of the ISPENDR
+ registers).
+
+ Accesses to GICD_ICPENDR register region and GICR_ICPENDR0 registers have
+ RAZ/WI semantics, meaning that reads always return 0 and writes are always
+ ignored.

+ -ENXIO: Getting or setting this register is not yet supported

+ | Aff3 | Aff2 | Aff1 | Aff0 |
+
+ The instr field encodes the system register to access based on the fields
+ defined in the A64 instruction set encoding for system register access
+ (RES means the bits are reserved for future use and should be zero):

+ The attr field of kvm_device_attr encodes the following values:
+ bits: | 63 .... 32 | 31 .... 10 | 9 .... 0 |
+ values: | mpidr | info | vINTID |
+
+ The vINTID specifies which set of IRQs is reported on.
+
+ The info field specifies which information userspace wants to get or set
+ using this interface. Currently we support the following info values:
+
+ VGIC_LEVEL_INFO_LINE_LEVEL:
+ Get/Set the input level of the IRQ line for a set of 32 contiguously
+ numbered interrupts.
+ vINTID must be a multiple of 32.
+
+ kvm_device_attr.addr points to a __u32 value which will contain a
+ bitmap where a set bit means the interrupt level is asserted.
+
+ Bit[n] indicates the status for interrupt vINTID + n.
+
+ SGIs and any interrupt with a higher ID than the number of interrupts
+ supported, will be RAZ/WI. LPIs are always edge-triggered and are
+ therefore not supported by this interface.
+
+ PPIs are reported per VCPU as specified in the mpidr field, and SPIs are
+ reported with the same value regardless of the mpidr specified.
+
+ The mpidr field encodes the CPU ID based on the affinity information in the
+ architecture defined MPIDR, and the field is encoded as follows:
+ | 63 .... 56 | 55 .... 48 | 47 .... 40 | 39 .... 32 |
+ | Aff3 | Aff2 | Aff1 | Aff0 |

+ An arch should select this symbol if it can support kernel stacks

+
+ - vmalloc space must be large enough to hold many kernel stacks.
+ This may rule out many 32-bit architectures.
+
+ - Stacks in vmalloc space need to work reliably. For example, if
+ vmap page tables are created on demand, either this mechanism
+ needs to work while the stack points to a virtual address with
+ unpopulated page tables or arch code (switch_to() and switch_mm(),
+ most likely) needs to ensure that the stack's page table entries
+ are populated before running on a possibly unpopulated stack.
+

+ * --------------------------------------------------
+ *
+ * Base is always 16. This is the ACPI_STRTOUL_BASE16 case.
+ *
+ * Example:
+ * Add ("BA98", Arg0, Local0)
+ *
+ * The integer is initialized to the value zero.
+ * The ASCII string is interpreted as a hexadecimal constant.
+ *
+ * 1) A "0x" prefix is not allowed. However, ACPICA allows this for
+ * compatibility with previous ACPICA. (NO ERROR)
+ *
+ * 2) Terminates when the size of an integer is reached (32 or 64 bits).
+ * (NO ERROR)
+ *
+ * 3) The first non-hex character terminates the conversion without error.
+ * (NO ERROR)
+ *
+ * 4) Conversion of a null (zero-length) string to an integer is not
+ * allowed. However, ACPICA allows this for compatibility with previous
+ * ACPICA. This conversion returns the value 0. (NO ERROR)
+ *
+ *
+ * Explicit data type conversion: to_integer() with string operand
+ * ---------------------------------------------------------------
+ *
+ * Base is either 10 (default) or 16 (with 0x prefix)
+ *
+ * Examples:
+ * to_integer ("1000")
+ * to_integer ("0xABCD")
+ *
+ * 1) Can be (must be) either a decimal or hexadecimal numeric string.
+ * A hex value must be prefixed by "0x" or it is interpreted as a decimal.
+ *
+ * 2) The value must not exceed the maximum of an integer value. ACPI spec
+ * states the behavior is "unpredictable", so ACPICA matches the behavior
+ * of the implicit conversion case.(NO ERROR)
+ *
+ * 3) Behavior on the first non-hex character is not specified by the ACPI
+ * spec, so ACPICA matches the behavior of the implicit conversion case
+ * and terminates. (NO ERROR)
+ *
+ * 4) A null (zero-length) string is illegal.

+ *
+ * DESCRIPTION: Convert a string into an unsigned value. Performs either a

+ * size in Flags (often the current mode of the interpreter).
+ *
+ * Values for Flags:
+ * ACPI_STRTOUL_32BIT - Max integer value is 32 bits
+ * ACPI_STRTOUL_64BIT - Max integer value is 64 bits
+ * ACPI_STRTOUL_BASE16 - Input string is hexadecimal. Default
+ * is 10/16 based on string prefix (0x).
+ *
+ * NOTES:
+ * Negative numbers are not supported, as they are not supported by ACPI.
+ *
+ * Supports only base 16 or base 10 strings/values. Does not
+ * support Octal strings, as these are not supported by ACPI.
+ *
+ * Current users of this support:
+ *
+ * interpreter - Implicit and explicit conversions, GPE method names
+ * debugger - Command line input string conversion
+ * iASL - Main parser, conversion of constants to integers
+ * iASL - Data Table Compiler parser (constant math expressions)
+ * iASL - Preprocessor (constant math expressions)
+ * acpi_dump - Input table addresses
+ * acpi_exec - Testing of the acpi_ut_strtoul64 function
+ *
+ * Note concerning callers:
+ * acpi_gbl_integer_byte_width can be used to set the 32/64 limit. If used,
+ * this global should be set to the proper width. For the core ACPICA code,
+ * this width depends on the DSDT version. For iASL, the default byte
+ * width is always 8 for the parser, but error checking is performed later
+ * to flag cases where a 64-bit constant is defined in a 32-bit DSDT/SSDT.

+ * currently executing in Phase-I
+ * 2. Once we start Phase-II we want to avoid all other CPUs from
+ * entering Phase-I.
+ * 3. We want only one CPU among all those who went through Phase-I
+ * to run phase-II
+ *
+ * If write_trylock fails to get the lock and doesn't transfer the
+ * PCC ownership to the platform, then one of the following will be TRUE
+ * 1. There is at-least one CPU in Phase-I which will later execute
+ * write_trylock, so the CPUs in Phase-I will be responsible for
+ * executing the Phase-II.
+ * 2. Some other CPU has beaten this CPU to successfully execute the
+ * write_trylock and has already acquired the write_lock. We know for a
+ * fact it(other CPU acquiring the write_lock) couldn't have happened
+ * before this CPU's Phase-I as we held the read_lock.
+ * 3. Some other CPU executing pcc CMD_READ has stolen the
+ * down_write, in which case, send_pcc_cmd will check for pending
+ * CMD_WRITE commands by checking the pending_pcc_write_cmd.
+ * So this CPU can be certain that its request will be delivered
+ * So in all cases, this CPU knows that its request will be delivered
+ * by another CPU and can return
+ *
+ * After getting the down_write we still need to check for
+ * pending_pcc_write_cmd to take care of the following scenario
+ * The thread running this code could be scheduled out between
+ * Phase-I and Phase-II. Before it is scheduled back on, another CPU
+ * could have delivered the request to Platform by triggering the
+ * doorbell and transferred the ownership of PCC to platform. So this
+ * avoids triggering an unnecessary doorbell and more importantly before
+ * triggering the doorbell it makes sure that the PCC channel ownership
+ * is still with OSPM.
+ * pending_pcc_write_cmd can also be cleared by a different CPU, if
+ * there was a pcc CMD_READ waiting on down_write and it steals the lock

+/**
+ * DOC: ZPA2326 theory of operations
+ *
+ * This driver supports %INDIO_DIRECT_MODE and %INDIO_BUFFER_TRIGGERED IIO
+ * modes.
+ * A internal hardware trigger is also implemented to dispatch registered IIO
+ * trigger consumers upon "sample ready" interrupts.
+ *
+ * ZPA2326 hardware supports 2 sampling mode: one shot and continuous.
+ *
+ * A complete one shot sampling cycle gets device out of low power mode,
+ * performs pressure and temperature measurements, then automatically switches
+ * back to low power mode. It is meant for on demand sampling with optimal power
+ * saving at the cost of lower sampling rate and higher software overhead.
+ * This is a natural candidate for IIO read_raw hook implementation
+ * (%INDIO_DIRECT_MODE). It is also used for triggered buffering support to
+ * ensure explicit synchronization with external trigger events
+ * (%INDIO_BUFFER_TRIGGERED).
+ *
+ * The continuous mode works according to a periodic hardware measurement
+ * process continuously pushing samples into an internal hardware FIFO (for
+ * pressure samples only). Measurement cycle completion may be signaled by a
+ * "sample ready" interrupt.
+ * Typical software sequence of operations :
+ * - get device out of low power mode,
+ * - setup hardware sampling period,
+ * - at end of period, upon data ready interrupt: pop pressure samples out of
+ * hardware FIFO and fetch temperature sample
+ * - when no longer needed, stop sampling process by putting device into
+ * low power mode.
+ * This mode is used to implement %INDIO_BUFFER_TRIGGERED mode if device tree
+ * declares a valid interrupt line. In this case, the internal hardware trigger
+ * drives acquisition.
+ *
+ * Note that hardware sampling frequency is taken into account only when
+ * internal hardware trigger is attached as the highest sampling rate seems to
+ * be the most energy efficient.
+ *
+ * TODO:
+ * preset pressure threshold crossing / IIO events ;
+ * differential pressure sampling ;
+ * hardware samples averaging.

- * This driver supports the bmp085 and bmp18x digital barometric pressure
- * and temperature sensors from Bosch Sensortec. The datasheets
- * are available from their website:
- * http://www.bosch-sensortec.com/content/language1/downloads/BST-BMP085-DS000-05.pdf
- * http://www.bosch-sensortec.com/content/language1/downloads/BST-BMP180-DS000-07.pdf
- *
- * A pressure measurement is issued by reading from pressure0_input.
- * The return value ranges from 30000 to 110000 pascal with a resulution
- * of 1 pascal (0.01 millibar) which enables measurements from 9000m above
- * to 500m below sea level.
- *
- * The temperature can be read from temp0_input. Values range from
- * -400 to 850 representing the ambient temperature in degree celsius
- * multiplied by 10.The resolution is 0.1 celsius.
- *
- * Because ambient pressure is temperature dependent, a temperature
- * measurement will be executed automatically even if the user is reading
- * from pressure0_input. This happens if the last temperature measurement
- * has been executed more then one second ago.
- *
- * To decrease RMS noise from pressure measurements, the bmp085 can
- * autonomously calculate the average of up to eight samples. This is
- * set up by writing to the oversampling sysfs file. Accepted values
- * are 0, 1, 2 and 3. 2^x when x is the value written to this file
- * specifies the number of samples used to calculate the ambient pressure.
- * RMS noise is specified with six pascal (without averaging) and decreases
- * down to 3 pascal when using an oversampling setting of 3.

+ *
+ * The ROCKCHIP Type-C PHY has two PLL clocks. The first PLL clock
+ * is used for USB3, the second PLL clock is used for DP. This Type-C PHY has
+ * 3 working modes: USB3 only mode, DP only mode, and USB3+DP mode.
+ * At USB3 only mode, both PLL clocks need to be initialized, this allows the
+ * PHY to switch mode between USB3 and USB3+DP, without disconnecting the USB
+ * device.
+ * In The DP only mode, only the DP PLL needs to be powered on, and the 4 lanes
+ * are all used for DP.
+ *
+ * This driver gets extcon cable state and property, then decides which mode to
+ * select:
+ *
+ * 1. USB3 only mode:
+ * EXTCON_USB or EXTCON_USB_HOST state is true, and
+ * EXTCON_PROP_USB_SS property is true.
+ * EXTCON_DISP_DP state is false.
+ *
+ * 2. DP only mode:
+ * EXTCON_DISP_DP state is true, and
+ * EXTCON_PROP_USB_SS property is false.
+ * If EXTCON_USB_HOST state is true, it is DP + USB2 mode, since the USB2 phy
+ * is a separate phy, so this case is still DP only mode.
+ *
+ * 3. USB3+DP mode:
+ * EXTCON_USB_HOST and EXTCON_DISP_DP are both true, and
+ * EXTCON_PROP_USB_SS property is true.
+ *
+ * This Type-C PHY driver supports normal and flip orientation. The orientation
+ * is reported by the EXTCON_PROP_USB_TYPEC_POLARITY property: true is flip
+ * orientation, false is normal orientation.

+ * The ASPEED SoCs provide typically more than 200 pins for GPIO and other
+ * functions. The SoC function enabled on a pin is determined on a priority
+ * basis where a given pin can provide a number of different signal types.
+ *
+ * The signal active on a pin is described by both a priority level and
+ * compound logical expressions involving multiple operators, registers and
+ * bits. Some difficulty arises as the pin's function bit masks for each
+ * priority level are frequently not the same (i.e. cannot just flip a bit to
+ * change from a high to low priority signal), or even in the same register.
+ * Further, not all signals can be unmuxed, as some expressions depend on
+ * values in the hardware strapping register (which is treated as read-only).
+ *
+ * SoC Multi-function Pin Expression Examples
+ * ------------------------------------------
+ *
+ * Here are some sample mux configurations from the AST2400 and AST2500
+ * datasheets to illustrate the corner cases, roughly in order of least to most
+ * corner. The signal priorities are in decending order from P0 (highest).
+ *
+ * D6 is a pin with a single function (beside GPIO); a high priority signal
+ * that participates in one function:
+ *
+ * Ball | Default | P0 Signal | P0 Expression | P1 Signal | P1 Expression | Other
+ * -----+---------+-----------+-----------------------------+-----------+---------------+----------
+ * D6 GPIOA0 MAC1LINK SCU80[0]=1 GPIOA0
+ * -----+---------+-----------+-----------------------------+-----------+---------------+----------
+ *
+ * C5 is a multi-signal pin (high and low priority signals). Here we touch
+ * different registers for the different functions that enable each signal:
+ *
+ * -----+---------+-----------+-----------------------------+-----------+---------------+----------
+ * C5 GPIOA4 SCL9 SCU90[22]=1 TIMER5 SCU80[4]=1 GPIOA4
+ * -----+---------+-----------+-----------------------------+-----------+---------------+----------
+ *
+ * E19 is a single-signal pin with two functions that influence the active
+ * signal. In this case both bits have the same meaning - enable a dedicated
+ * LPC reset pin. However it's not always the case that the bits in the
+ * OR-relationship have the same meaning.
+ *
+ * -----+---------+-----------+-----------------------------+-----------+---------------+----------
+ * E19 GPIOB4 LPCRST# SCU80[12]=1 | Strap[14]=1 GPIOB4
+ * -----+---------+-----------+-----------------------------+-----------+---------------+----------
+ *
+ * For example, pin B19 has a low-priority signal that's enabled by two
+ * distinct SoC functions: A specific SIOPBI bit in register SCUA4, and an ACPI
+ * bit in the STRAP register. The ACPI bit configures signals on pins in
+ * addition to B19. Both of the low priority functions as well as the high
+ * priority function must be disabled for GPIOF1 to be used.
+ *
+ * Ball | Default | P0 Signal | P0 Expression | P1 Signal | P1 Expression | Other
+ * -----+---------+-----------+-----------------------------------------+-----------+----------------------------------------+----------
+ * B19 GPIOF1 NDCD4 SCU80[25]=1 SIOPBI# SCUA4[12]=1 | Strap[19]=0 GPIOF1
+ * -----+---------+-----------+-----------------------------------------+-----------+----------------------------------------+----------
+ *
+ * For pin E18, the SoC ANDs the expected state of three bits to determine the
+ * pin's active signal:
+ *
+ * * SCU3C[3]: Enable external SOC reset function
+ * * SCU80[15]: Enable SPICS1# or EXTRST# function pin
+ * * SCU90[31]: Select SPI interface CS# output
+ *
+ * -----+---------+-----------+-----------------------------------------+-----------+----------------------------------------+----------
+ * E18 GPIOB7 EXTRST# SCU3C[3]=1 & SCU80[15]=1 & SCU90[31]=0 SPICS1# SCU3C[3]=1 & SCU80[15]=1 & SCU90[31]=1 GPIOB7
+ * -----+---------+-----------+-----------------------------------------+-----------+----------------------------------------+----------
+ *
+ * (Bits SCU3C[3] and SCU80[15] appear to only be used in the expressions for
+ * selecting the signals on pin E18)
+ *
+ * Pin T5 is a multi-signal pin with a more complex configuration:
+ *
+ * Ball | Default | P0 Signal | P0 Expression | P1 Signal | P1 Expression | Other
+ * -----+---------+-----------+------------------------------+-----------+---------------+----------
+ * T5 GPIOL1 VPIDE SCU90[5:4]!=0 & SCU84[17]=1 NDCD1 SCU84[17]=1 GPIOL1
+ * -----+---------+-----------+------------------------------+-----------+---------------+----------
+ *
+ * The high priority signal configuration is best thought of in terms of its
+ * exploded form, with reference to the SCU90[5:4] bits:
+ *
+ * * SCU90[5:4]=00: disable
+ * * SCU90[5:4]=01: 18 bits (R6/G6/B6) video mode.
+ * * SCU90[5:4]=10: 24 bits (R8/G8/B8) video mode.
+ * * SCU90[5:4]=11: 30 bits (R10/G10/B10) video mode.
+ *
+ * Re-writing:
+ *
+ * -----+---------+-----------+------------------------------+-----------+---------------+----------
+ * T5 GPIOL1 VPIDE (SCU90[5:4]=1 & SCU84[17]=1) NDCD1 SCU84[17]=1 GPIOL1
+ * | (SCU90[5:4]=2 & SCU84[17]=1)
+ * | (SCU90[5:4]=3 & SCU84[17]=1)
+ * -----+---------+-----------+------------------------------+-----------+---------------+----------
+ *
+ * For reference the SCU84[17] bit configure the "UART1 NDCD1 or Video VPIDE
+ * function pin", where the signal itself is determined by whether SCU94[5:4]
+ * is disabled or in one of the 18, 24 or 30bit video modes.
+ *
+ * Other video-input-related pins require an explicit state in SCU90[5:4], e.g.
+ * W1 and U5:
+ *
+ * -----+---------+-----------+------------------------------+-----------+---------------+----------
+ * W1 GPIOL6 VPIB0 SCU90[5:4]=3 & SCU84[22]=1 TXD1 SCU84[22]=1 GPIOL6
+ * U5 GPIOL7 VPIB1 SCU90[5:4]=3 & SCU84[23]=1 RXD1 SCU84[23]=1 GPIOL7
+ * -----+---------+-----------+------------------------------+-----------+---------------+----------
+ *
+ * The examples of T5 and W1 are particularly fertile, as they also demonstrate
+ * that despite operating as part of the video input bus each signal needs to
+ * be enabled individually via it's own SCU84 (in the cases of T5 and W1)
+ * register bit. This is a little crazy if the bus doesn't have optional
+ * signals, but is used to decent effect with some of the UARTs where not all
+ * signals are required. However, this isn't done consistently - UART1 is
+ * enabled on a per-pin basis, and by contrast, all signals for UART6 are
+ * enabled by a single bit.
+ *
+ * Further, the high and low priority signals listed in the table above share
+ * a configuration bit. The VPI signals should operate in concert in a single
+ * function, but the UART signals should retain the ability to be configured
+ * independently. This pushes the implementation down the path of tagging a
+ * signal's expressions with the function they participate in, rather than
+ * defining masks affecting multiple signals per function. The latter approach
+ * fails in this instance where applying the configuration for the UART pin of
+ * interest will stomp on the state of other UART signals when disabling the
+ * VPI functions on the current pin.
+ *
+ * Ball | Default | P0 Signal | P0 Expression | P1 Signal | P1 Expression | Other
+ * -----+------------+-----------+---------------------------+-----------+---------------+------------
+ * A12 RGMII1TXCK GPIOT0 SCUA0[0]=1 RMII1TXEN Strap[6]=0 RGMII1TXCK
+ * B12 RGMII1TXCTL GPIOT1 SCUA0[1]=1 – Strap[6]=0 RGMII1TXCTL
+ * -----+------------+-----------+---------------------------+-----------+---------------+------------
+ *
+ * A12 demonstrates that the "Other" signal isn't always GPIO - in this case
+ * GPIOT0 is a high-priority signal and RGMII1TXCK is Other. Thus, GPIO
+ * should be treated like any other signal type with full function expression
+ * requirements, and not assumed to be the default case. Separately, GPIOT0 and
+ * GPIOT1's signal descriptor bits are distinct, therefore we must iterate all
+ * pins in the function's group to disable the higher-priority signals such
+ * that the signal for the function of interest is correctly enabled.
+ *
+ * Finally, three priority levels aren't always enough; the AST2500 brings with
+ * it 18 pins of five priority levels, however the 18 pins only use three of
+ * the five priority levels.
+ *
+ * Ultimately the requirement to control pins in the examples above drive the
+ * design:
+ *
+ * * Pins provide signals according to functions activated in the mux
+ * configuration
+ *
+ * * Pins provide up to five signal types in a priority order
+ *
+ * * For priorities levels defined on a pin, each priority provides one signal
+ *
+ * * Enabling lower priority signals requires higher priority signals be
+ * disabled
+ *
+ * * A function represents a set of signals; functions are distinct if their
+ * sets of signals are not equal
+ *
+ * * Signals participate in one or more functions
+ *
+ * * A function is described by an expression of one or more signal
+ * descriptors, which compare bit values in a register
+ *
+ * * A signal expression is the smallest set of signal descriptors whose
+ * comparisons must evaluate 'true' for a signal to be enabled on a pin.
+ *
+ * * A function's signal is active on a pin if evaluating all signal
+ * descriptors in the pin's signal expression for the function yields a 'true'
+ * result
+ *
+ * * A signal at a given priority on a given pin is active if any of the
+ * functions in which the signal participates are active, and no higher
+ * priority signal on the pin is active
+ *
+ * * GPIO is configured per-pin
+ *
+ * And so:
+ *
+ * * To disable a signal, any function(s) activating the signal must be
+ * disabled
+ *
+ * * Each pin must know the signal expressions of functions in which it
+ * participates, for the purpose of enabling the Other function. This is done
+ * by deactivating all functions that activate higher priority signals on the
+ * pin.
+ *
+ * As a concrete example:
+ *
+ * * T5 provides three signals types: VPIDE, NDCD1 and GPIO
+ *
+ * * The VPIDE signal participates in 3 functions: VPI18, VPI24 and VPI30
+ *
+ * * The NDCD1 signal participates in just its own NDCD1 function
+ *
+ * * VPIDE is high priority, NDCD1 is low priority, and GPIOL1 is the least
+ * prioritised
+ *
+ * * The prerequisit for activating the NDCD1 signal is that the VPI18, VPI24
+ * and VPI30 functions all be disabled
+ *
+ * * Similarly, all of VPI18, VPI24, VPI30 and NDCD1 functions must be disabled
+ * to provide GPIOL6
+ *
+ * Considerations
+ * --------------
+ *
+ * If pinctrl allows us to allocate a pin we can configure a function without
+ * concern for the function of already allocated pins, if pin groups are
+ * created with respect to the SoC functions in which they participate. This is
+ * intuitive, but it did not feel obvious from the bit/pin relationships.
+ *
+ * Conversely, failing to allocate all pins in a group indicates some bits (as
+ * well as pins) required for the group's configuration will already be in use,
+ * likely in a way that's inconsistent with the requirements of the failed
+ * group.

+Ion Memory Manager
+
+Ion is a memory manager that allows for sharing of buffers via dma-buf.
+Ion allows for different types of allocation via an abstraction called
+a 'heap'. A heap represents a specific type of memory. Each heap has
+a different type. There can be multiple instances of the same heap
+type.
+
+Specific heap instances are tied to heap IDs. Heap IDs are not to be specified
+in the devicetree.
+
+Required properties for Ion
+
+- compatible: "linux,ion" PLUS a compatible property for the device
+
+All child nodes of a linux,ion node are interpreted as heaps
+
+required properties for heaps
+
+- compatible: compatible string for a heap type PLUS a compatible property
+for the specific instance of the heap. Current heap types
+-- linux,ion-heap-system
+-- linux,ion-heap-system-contig
+-- linux,ion-heap-carveout
+-- linux,ion-heap-chunk
+-- linux,ion-heap-dma
+-- linux,ion-heap-custom
+
+Optional properties
+- memory-region: A phandle to a memory region. Required for DMA heap type
+(see reserved-memory.txt for details on the reservation)
+
+Example:
+
+ ion {
+ compatbile = "hisilicon,ion", "linux,ion";
+
+ ion-system-heap {
+ compatbile = "hisilicon,system-heap", "linux,ion-heap-system"
+ };
+
+ ion-camera-region {
+ compatible = "hisilicon,camera-heap", "linux,ion-heap-dma"
+ memory-region = <&camera_region>;
+ };
+
+ ion-fb-region {
+ compatbile = "hisilicon,fb-heap", "linux,ion-heap-dma"

+ * - 1 12-bit watchdog/timer
+ *
+ * There are 2 versions of the APCI-3501:

+Firmware Management
+-------------------
+ Copyright 2016 Google Inc.
+ Copyright 2016 Linaro Ltd.
+
+Interface-Manifest
+------------------
+
+All firmware packages on the Modules or Interfaces are managed by a special
+Firmware Management Protocol. To support Firmware Management by the AP, the
+Interface Manifest shall at least contain the Firmware Management Bundle and a
+Firmware Management Protocol CPort within it.
+
+The bundle may contain additional CPorts based on the extra functionality
+required to manage firmware packages.
+
+For example, this is how the Firmware Management part of the Interface Manifest
+may look like:
+
+ ; Firmware Management Bundle (Bundle 1):
+ [bundle-descriptor 1]
+ class = 0x16
+
+ ; (Mandatory) Firmware Management Protocol on CPort 1
+ [cport-descriptor 2]
+ bundle = 1
+ protocol = 0x18
+
+ ; (Optional) Firmware Download Protocol on CPort 2
+ [cport-descriptor 1]
+ bundle = 1
+ protocol = 0x17
+
+ ; (Optional) SPI protocol on CPort 3
+ [cport-descriptor 3]
+ bundle = 1
+ protocol = 0x0b
+
+ ; (Optional) Component Authentication Protocol (CAP) on CPort 4
+ [cport-descriptor 4]
+ bundle = 1
+ protocol = 0x19
+
+
+Sysfs Interfaces - Firmware Management
+--------------------------------------
+
+The Firmware Management Protocol interacts with Userspace using the character
+device interface. The character device will be present in /dev/ directory
+and will be named gb-fw-mgmt-<N>. The number <N> is assigned at runtime.
+
+Identifying the Character Device
+================================
+
+There can be multiple devices present in /dev/ directory with name gb-fw-mgmt-N
+and user first needs to identify the character device used for
+firmware-management for a particular interface.
+
+The Firmware Management core creates a device of class 'gb_fw_mgmt', which shall
+be used by the user to identify the right character device for it. The class
+device is created within the Bundle directory for a particular Interface.
+
+For example this is how the class-device can be present:
+
+/sys/bus/greybus/devices/1-1/1-1.1/1-1.1.1/gb_fw_mgmt/gb-fw-mgmt-0
+
+The last name in this path: gb-fw-mgmt-0 is precisely the name of the char
+device and so the device in this case will be:
+
+/dev/gb-fw-mgmt-0.
+
+Operations on the Char device
+=============================
+
+The Character device (gb-fw-mgmt-0 in example) can be opened by the userspace
+application and it can perform various 'ioctl' operations on the device. The
+device doesn't support any read/write operations.
+
+Following are the IOCTLs and their data structures available to the user:

+
+1. FW_MGMT_IOC_GET_INTF_FW:
+
+ This ioctl shall be used by the user to get the version and firmware-tag of

+
+2. FW_MGMT_IOC_GET_BACKEND_FW:
+
+ This ioctl shall be used by the user to get the version of a currently
+ running Backend Interface Firmware identified by a firmware-tag. The user is
+ required to fill the 'firmware_tag' field of the 'struct fw_mgmt_ioc_get_fw'
+ in this case. The 'major' and 'minor' fields are set by the kernel in
+ response.
+
+3. FW_MGMT_IOC_INTF_LOAD_AND_VALIDATE:
+
+ This ioctl shall be used by the user to load an Interface Firmware package on
+ an Interface. The user needs to fill the 'firmware_tag' and 'load_method'
+ fields of the 'struct fw_mgmt_ioc_intf_load_and_validate'. The 'status',
+ 'major' and 'minor' fields are set by the kernel in response.
+
+4. FW_MGMT_IOC_INTF_BACKEND_FW_UPDATE:
+
+ This ioctl shall be used by the user to request an Interface to update a
+ Backend Interface Firmware. The user is required to fill the 'firmware_tag'
+ field of the 'struct fw_mgmt_ioc_get_fw' in this case. The 'status' field is
+ set by the kernel in response.
+
+5. FW_MGMT_IOC_SET_TIMEOUT_MS:
+
+ This ioctl shall be used by the user to increase the timeout interval within
+ which the firmware must get loaded by the Module. The default timeout is 1
+ second. The user needs to pass the timeout in milliseconds.
+
+6. FW_MGMT_IOC_MODE_SWITCH:
+
+ This ioctl shall be used by the user to mode-switch the module to the
+ previously loaded interface firmware. If the interface firmware isn't loaded
+ previously, or if another unsuccessful FW_MGMT_IOC_INTF_LOAD_AND_VALIDATE
+ operation is started after loading interface firmware, then the firmware core
+ wouldn't allow mode-switch.
+
+
+Sysfs Interfaces - Authentication
+---------------------------------
+
+The Component Authentication Protocol interacts with Userspace using the
+character device interface. The character device will be present in /dev/
+directory and will be named gb-authenticate-<N>. The number <N> is assigned at
+runtime.
+
+Identifying the Character Device
+================================
+
+There can be multiple devices present in /dev/ directory with name
+gb-authenticate-N and user first needs to identify the character device used for
+authentication a of particular interface.
+
+The Authentication core creates a device of class 'gb_authenticate', which shall
+be used by the user to identify the right character device for it. The class
+device is created within the Bundle directory for a particular Interface.
+
+For example this is how the class-device can be present:
+
+/sys/bus/greybus/devices/1-1/1-1.1/1-1.1.1/gb_authenticate/gb-authenticate-0
+
+The last name in this path: gb-authenticate-0 is precisely the name of the char
+device and so the device in this case will be:
+
+/dev/gb-authenticate-0.
+
+Operations on the Char device
+=============================
+
+The Character device (/dev/gb-authenticate-0 in above example) can be opened by
+the userspace application and it can perform various 'ioctl' operations on the
+device. The device doesn't support any read/write operations.
+
+Following are the IOCTLs and their data structures available to the user:

+
+
+1. CAP_IOC_GET_ENDPOINT_UID:
+
+ This ioctl shall be used by the user to get the endpoint UID associated with
+ the Interface. All the fields of the 'struct cap_ioc_get_endpoint_uid' are
+ filled by the kernel.
+
+2. CAP_IOC_GET_IMS_CERTIFICATE:
+
+ This ioctl shall be used by the user to retrieve one of the available
+ cryptographic certificates held by the Interface for use in Component
+ Authentication. The user is required to fill the 'certificate_class' and
+ 'certificate_id' field of the 'struct cap_ioc_get_ims_certificate' in this
+ case. The other fields will be set by the kernel in response. The first
+ 'cert_size' bytes of the 'certificate' shall be read by the user and others
+ must be discarded.
+
+3. CAP_IOC_AUTHENTICATE:
+
+ This ioctl shall be used by the user to authenticate the Module attached to
+ an Interface. The user needs to fill the 'auth_type', 'uid', and 'challenge'
+ fields of the 'struct cap_ioc_authenticate'. The other fields will be set by
+ the kernel in response. The first 'signature_size' bytes of the 'signature'
+ shall be read by the user and others must be discarded.
+
+
+Sysfs Interfaces - Firmware Download
+------------------------------------
+
+The Firmware Download Protocol uses the existing Linux Kernel's Firmware class
+and the interface provided to userspace are described in:
+Documentation/firmware_class/.
+
+
+Sysfs Interfaces - SPI Flash
+----------------------------
+
+The SPI flash is exposed in userspace as a MTD device and is created
+within the Bundle directory. For example, this is how the path may look like:
+
+$ ls /sys/bus/greybus/devices/1-1/1-1.1/1-1.1.1/spi_master/spi32766/spi32766.0/mtd
+mtd0 mtd0ro
+
+
+Sample Applications
+-------------------
+
+The current directory also provides a firmware.c test application, which can be
+referenced while developing userspace application to talk to firmware-management
+protocol.
+
+The current directory also provides a authenticate.c test application, which can
+be referenced while developing userspace application to talk to
+component authentication protocol.

+ * - there are two channels (i.e., stereo)
+ * - the low-level protocol is I2S as defined by Philips/NXP
+ * - the DSP on the MSM8994 is the clock master for MCLK, BCLK, and WCLK
+ * - WCLK changes on the falling edge of BCLK
+ * - WCLK low for left channel; high for right channel
+ * - TX data is sent on the falling edge of BCLK
+ * - RX data is received/latched on the rising edge of BCLK

+ 1 - LOOPBACK DRIVER
+
+The driver implements the main logic of the loopback test and provides
+sysfs files to configure the test and retrieve the results.
+A user could run a test without the need of the test application given
+that he understands the sysfs interface of the loopback driver.
+
+The loopback kernel driver needs to be loaded and at least one module
+with the loopback feature enabled must be present for the sysfs files to be
+created and for the loopback test application to be able to run.
+
+To load the module:
+# modprobe gb-loopback
+
+
+When the module is probed, New files are available on the sysfs
+directory of the detected loopback device.
+(typically under "/sys/bus/graybus/devices").
+
+Here is a short summary of the sysfs interface files that should be visible:
+
+* Loopback Configuration Files:
+ async - Use asynchronous operations.
+ iteration_max - Number of tests iterations to perform.
+ size - payload size of the transfer.
+ timeout - The number of microseconds to give an individual
+ asynchronous request before timing out.
+ us_wait - Time to wait between 2 messages
+ type - By writing the test type to this file, the test starts.
+ Valid tests are:
+ 0 stop the test
+ 2 - ping
+ 3 - transfer
+ 4 - sink
+
+* Loopback feedback files:
+ error - number of errors that have occurred.
+ iteration_count - Number of iterations performed.
+ requests_completed - Number of requests successfully completed.
+ requests_timedout - Number of requests that have timed out.
+ timeout_max - Max allowed timeout
+ timeout_min - Min allowed timeout.
+
+* Loopback result files:
+ apbridge_unipro_latency_avg
+ apbridge_unipro_latency_max
+ apbridge_unipro_latency_min
+ gpbridge_firmware_latency_avg
+ gpbridge_firmware_latency_max
+ gpbridge_firmware_latency_min
+ requests_per_second_avg
+ requests_per_second_max
+ requests_per_second_min
+ latency_avg
+ latency_max
+ latency_min
+ throughput_avg
+ throughput_max
+ throughput_min
+
+
+
+ 2 - LOOPBACK TEST APPLICATION
+
+The loopback test application manages and formats the results provided by
+the loopback kernel module. The purpose of this application
+is to:
+ - Start and manage multiple loopback device tests concurrently.
+ - Calculate the aggregate results for multiple devices.
+ - Gather and format test results (csv or human readable).
+
+The best way to get up to date usage information for the application is
+usually to pass the "-h" parameter.
+Here is the summary of the available options:
+
+ Mandatory arguments
+ -t must be one of the test names - sink, transfer or ping
+ -i iteration count - the number of iterations to run the test over
+ Optional arguments
+ -S sysfs location - location for greybus 'endo' entires default /sys/bus/greybus/devices/
+ -D debugfs location - location for loopback debugfs entries default /sys/kernel/debug/gb_loopback/
+ -s size of data packet to send during test - defaults to zero
+ -m mask - a bit mask of connections to include example: -m 8 = 4th connection -m 9 = 1st and 4th connection etc
+ default is zero which means broadcast to all connections
+ -v verbose output
+ -d debug output
+ -r raw data output - when specified the full list of latency values are included in the output CSV
+ -p porcelain - when specified printout is in a user-friendly non-CSV format. This option suppresses writing to CSV file
+ -a aggregate - show aggregation of all enabled devies
+ -l list found loopback devices and exit.
+ -x Async - Enable async transfers.
+ -o Timeout - Timeout in microseconds for async operations.
+
+
+
+ 3 - REAL WORLD EXAMPLE USAGES
+
+ 3.1 - Using the driver sysfs files to run a test on a single device:
+
+* Run a 1000 transfers of a 100 byte packet. Each transfer is started only
+after the previous one finished successfully:
+ echo 0 > /sys/bus/greybus/devices/1-2.17/type
+ echo 0 > /sys/bus/greybus/devices/1-2.17/async
+ echo 2000 > /sys/bus/greybus/devices/1-2.17/us_wait
+ echo 100 > /sys/bus/greybus/devices/1-2.17/size
+ echo 1000 > /sys/bus/greybus/devices/1-2.17/iteration_max
+ echo 0 > /sys/bus/greybus/devices/1-2.17/mask
+ echo 200000 > /sys/bus/greybus/devices/1-2.17/timeout
+ echo 3 > /sys/bus/greybus/devices/1-2.17/type
+
+* Run a 1000 transfers of a 100 byte packet. Transfers are started without
+waiting for the previous one to finish:
+ echo 0 > /sys/bus/greybus/devices/1-2.17/type
+ echo 3 > /sys/bus/greybus/devices/1-2.17/async
+ echo 0 > /sys/bus/greybus/devices/1-2.17/us_wait
+ echo 100 > /sys/bus/greybus/devices/1-2.17/size
+ echo 1000 > /sys/bus/greybus/devices/1-2.17/iteration_max
+ echo 0 > /sys/bus/greybus/devices/1-2.17/mask
+ echo 200000 > /sys/bus/greybus/devices/1-2.17/timeout
+ echo 3 > /sys/bus/greybus/devices/1-2.17/type
+
+* Read the results from sysfs:
+ cat /sys/bus/greybus/devices/1-2.17/requests_per_second_min
+ cat /sys/bus/greybus/devices/1-2.17/requests_per_second_max
+ cat /sys/bus/greybus/devices/1-2.17/requests_per_second_avg
+
+ cat /sys/bus/greybus/devices/1-2.17/latency_min
+ cat /sys/bus/greybus/devices/1-2.17/latency_max
+ cat /sys/bus/greybus/devices/1-2.17/latency_avg
+
+ cat /sys/bus/greybus/devices/1-2.17/apbridge_unipro_latency_min
+ cat /sys/bus/greybus/devices/1-2.17/apbridge_unipro_latency_max
+ cat /sys/bus/greybus/devices/1-2.17/apbridge_unipro_latency_avg
+
+ cat /sys/bus/greybus/devices/1-2.17/gpbridge_firmware_latency_min
+ cat /sys/bus/greybus/devices/1-2.17/gpbridge_firmware_latency_max
+ cat /sys/bus/greybus/devices/1-2.17/gpbridge_firmware_latency_avg
+
+ cat /sys/bus/greybus/devices/1-2.17/error
+ cat /sys/bus/greybus/devices/1-2.17/requests_completed
+ cat /sys/bus/greybus/devices/1-2.17/requests_timedout
+
+
+3.2 - using the test application:
+
+* Run a transfer test 10 iterations of size 100 bytes on all available devices

*

*
+ * Subsystem Description:
+ * FLD is FID Location Database, which stores where (IE, on which MDT)
+ * FIDs are located.
+ * The database is basically a record file, each record consists of a FID
+ * sequence range, MDT/OST index, and flags. The FLD for the whole FS
+ * is only stored on the sequence controller(MDT0) right now, but each target
+ * also has its local FLD, which only stores the local sequence.
+ *
+ * The FLD subsystem usually has two tasks:
+ * 1. maintain the database, i.e. when the sequence controller allocates
+ * new sequence ranges to some nodes, it will call the FLD API to insert the
+ * location information <sequence_range, node_index> in FLDB.
+ *
+ * 2. Handle requests from other nodes, i.e. if client needs to know where
+ * the FID is located, if it can not find the information in the local cache,
+ * it will send a FLD lookup RPC to the FLD service, and the FLD service will
+ * look up the FLDB entry and return the location information to client.

-TODO:
-- find and remove code valid only for 5 HGz. Many of the obvious
- ones have been removed, but things like channel > 14 still exist.
-- find and remove any code for other chips that is left over
-- convert any remaining unusual variable types
-- find codes that can use %pM and %Nph formatting
-- checkpatch.pl fixes - most of the remaining ones are lines too long. Many
- of them will require refactoring
-- merge Realtek's bugfixes and new features into the driver
-- switch to use MAC80211
-
-A mac80211 driver for this hardware already was integrated at
-drivers/net/wireless/realtek/rtl8xxxu/
-
-Please send any patches to Greg Kroah-Hartman <gregkh@linuxfoundation.org>,
-Jes Sorensen <Jes.Sorensen@redhat.com>, and Larry Finger <Larry.Finger@lwfinger.net>.

- * Usage:
- * When one iface acted as AP mode and the other iface is STA mode and scanning,

- * Parameters info:
- * When the driver scanned RTW_SCAN_NUM_OF_CH channels, it would switch back to AP's operating channel for
- * RTW_STAY_AP_CH_MILLISECOND * SURVEY_TO milliseconds.
- * Example:
- * For chip supports 2.4G + 5GHz and AP mode is operating in channel 1,
- * RTW_SCAN_NUM_OF_CH is 8, RTW_STAY_AP_CH_MILLISECOND is 3 and SURVEY_TO is 100.
- * When it's STA mode gets set_scan command,
- * it would
- * 1. Doing the scan on channel 1.2.3.4.5.6.7.8
- * 2. Back to channel 1 for 300 milliseconds
- * 3. Go through doing site survey on channel 9.10.11.36.40.44.48.52
- * 4. Back to channel 1 for 300 milliseconds
- * 5. ... and so on, till survey done.

*
- * Here's how the whole Linux bus / driver / device model works.
- *
- * At system start-up, the visorbus kernel module is loaded, which registers
- * visorbus_type as a bus type, using bus_register().
- *
- * All kernel modules that support particular device types on a
- * visorbus bus are loaded. Each of these kernel modules calls
- * visorbus_register_visor_driver() in their init functions, passing a
- * visor_driver struct. visorbus_register_visor_driver() in turn calls
- * register_driver(&visor_driver.driver). This .driver member is
- * initialized with generic methods (like probe), whose sole responsibility
- * is to act as a broker for the real methods, which are within the
- * visor_driver struct. (This is the way the subclass behavior is
- * implemented, since visor_driver is essentially a subclass of the
- * generic driver.) Whenever a driver_register() happens, core bus code in
- * the kernel does (see device_attach() in drivers/base/dd.c):
- *
- * for each dev associated with the bus (the bus that driver is on) that
- * does not yet have a driver
- * if bus.match(dev,newdriver) == yes_matched ** .match specified
- * ** during bus_register().
- * newdriver.probe(dev) ** for visor drivers, this will call
- * ** the generic driver.probe implemented in visorbus.c,
- * ** which in turn calls the probe specified within the
- * ** struct visor_driver (which was specified by the
- * ** actual device driver as part of
- * ** visorbus_register_visor_driver()).
- *
- * The above dance also happens when a new device appears.
- * So the question is, how are devices created within the system?
- * Basically, just call device_add(dev). See pci_bus_add_devices().
- * pci_scan_device() shows an example of how to build a device struct. It
- * returns the newly-created struct to pci_scan_single_device(), who adds it
- * to the list of devices at PCIBUS.devices. That list of devices is what
- * is traversed by pci_bus_add_devices().

+ * the driver. The caller MUST fill in the following fields within the
+ * #drv structure:
+ * name, version, owner, channel_types, probe, remove
+ *
+ * Here's how the whole Linux bus / driver / device model works.
+ *
+ * At system start-up, the visorbus kernel module is loaded, which registers
+ * visorbus_type as a bus type, using bus_register().
+ *
+ * All kernel modules that support particular device types on a
+ * visorbus bus are loaded. Each of these kernel modules calls
+ * visorbus_register_visor_driver() in their init functions, passing a
+ * visor_driver struct. visorbus_register_visor_driver() in turn calls
+ * register_driver(&visor_driver.driver). This .driver member is
+ * initialized with generic methods (like probe), whose sole responsibility
+ * is to act as a broker for the real methods, which are within the
+ * visor_driver struct. (This is the way the subclass behavior is
+ * implemented, since visor_driver is essentially a subclass of the
+ * generic driver.) Whenever a driver_register() happens, core bus code in
+ * the kernel does (see device_attach() in drivers/base/dd.c):
+ *
+ * for each dev associated with the bus (the bus that driver is on) that
+ * does not yet have a driver
+ * if bus.match(dev,newdriver) == yes_matched ** .match specified
+ * ** during bus_register().
+ * newdriver.probe(dev) ** for visor drivers, this will call
+ * ** the generic driver.probe implemented in visorbus.c,
+ * ** which in turn calls the probe specified within the
+ * ** struct visor_driver (which was specified by the
+ * ** actual device driver as part of
+ * ** visorbus_register_visor_driver()).
+ *
+ * The above dance also happens when a new device appears.
+ * So the question is, how are devices created within the system?
+ * Basically, just call device_add(dev). See pci_bus_add_devices().
+ * pci_scan_device() shows an example of how to build a device struct. It
+ * returns the newly-created struct to pci_scan_single_device(), who adds it
+ * to the list of devices at PCIBUS.devices. That list of devices is what
+ * is traversed by pci_bus_add_devices().

+** Functions to modify the state variables;
+** set_suspend_state
+** set_resume_state
+**
+** There are more state variables than we might like, so ensure they remain in
+** step. Suspend and resume state are maintained separately, since most of
+** these state machines can operate independently. However, there are a few
+** states where state transitions in one state machine cause a reset to the
+** other state machine. In addition, there are some completion events which
+** need to occur on state machine reset and end-state(s), so these are also
+** dealt with in these functions.
+**
+** In all states we set the state variable according to the input, but in some
+** cases we perform additional steps outlined below;
+**
+** VC_SUSPEND_IDLE - Initialise the suspend completion at the same time.
+** The suspend completion is completed after any suspend
+** attempt. When we reset the state machine we also reset
+** the completion. This reset occurs when videocore is
+** resumed, and also if we initiate suspend after a suspend
+** failure.
+**
+** VC_SUSPEND_IN_PROGRESS - This state is considered the point of no return for
+** suspend - ie from this point on we must try to suspend
+** before resuming can occur. We therefore also reset the
+** resume state machine to VC_RESUME_IDLE in this state.
+**
+** VC_SUSPEND_SUSPENDED - Suspend has completed successfully. Also call
+** complete_all on the suspend completion to notify
+** anything waiting for suspend to happen.
+**
+** VC_SUSPEND_REJECTED - Videocore rejected suspend. Videocore will also
+** initiate resume, so no need to alter resume state.
+** We call complete_all on the suspend completion to notify
+** of suspend rejection.
+**
+** VC_SUSPEND_FAILED - We failed to initiate videocore suspend. We notify the
+** suspend completion and reset the resume state machine.
+**
+** VC_RESUME_IDLE - Initialise the resume completion at the same time. The
+** resume completion is in it's 'done' state whenever
+** videcore is running. Therfore, the VC_RESUME_IDLE state
+** implies that videocore is suspended.
+** Hence, any thread which needs to wait until videocore is
+** running can wait on this completion - it will only block
+** if videocore is suspended.
+**
+** VC_RESUME_RESUMED - Resume has completed successfully. Videocore is running.
+** Call complete_all on the resume completion to unblock
+** any threads waiting for resume. Also reset the suspend
+** state machine to it's idle state.
+**
+** VC_RESUME_FAILED - Currently unused - no mechanism to fail resume exists.

+ UTMI+ Low Pin Interface (ULPI) is specification for a commonly used
+ USB 2.0 PHY interface. The ULPI specification defines a standard set
+ of registers that can be used to detect the vendor and product which
+ allows ULPI to be handled as a bus. This module is the driver for that
+ bus.
+
+ The ULPI interfaces (the buses) are registered by the drivers for USB
+ controllers which support ULPI register access and have ULPI PHY
+ attached to them. The ULPI PHY drivers themselves are normal PHY
+ drivers.
+
+ ULPI PHYs provide often functions such as ADP sensing/probing (OTG
+ protocol) and USB charger detection.
+
+ To compile this driver as a module, choose M here: the module will
+ be called ulpi.

+ *
+ * Quoting section 7 of the CDC-WMC r1.1 specification:
+ *
+ * "The firmware shall interpret GetEncapsulatedResponse as a
+ * request to read response bytes. The firmware shall send
+ * the next wLength bytes from the response. The firmware
+ * shall allow the host to retrieve data using any number of
+ * GetEncapsulatedResponse requests. The firmware shall
+ * return a zero- length reply if there are no data bytes
+ * available.
+ *
+ * The firmware shall send ResponseAvailable notifications
+ * periodically, using any appropriate algorithm, to inform
+ * the host that there is data available in the reply
+ * buffer. The firmware is allowed to send ResponseAvailable
+ * notifications even if there is no data available, but
+ * this will obviously reduce overall performance."
+ *
+ * These requirements, although they make equally sense, are
+ * often not implemented by network functions. Some firmwares
+ * will queue data indefinitely, without ever resending a
+ * notification. The result is that the driver and firmware
+ * loses "syncronization" if the driver ever fails to respond
+ * to a single notification, something which easily can happen
+ * on release(). When this happens, the driver will appear to
+ * never receive notifications for the most current data. Each
+ * notification will only cause a single read, which returns
+ * the oldest data in the firmware's queue.
+ *
+ * The "drain_on_open" hack resolves the situation by draining
+ * data from the firmware until none is returned, without a
+ * prior notification.
+ *
+ * This will inevitably race with the firmware, risking that
+ * we read data from the device before handling the associated
+ * notification. To make things worse, some of the devices
+ * needing the hack do not implement the "return zero if no
+ * data is available" requirement either. Instead they return
+ * an error on the subsequent read in this case. This means
+ * that "winning" the race can cause an unexpected EIO to
+ * userspace.
+ *
+ * "winning" the race is more likely on resume() than on
+ * open(), and the unexpected error is more harmful in the
+ * middle of an open session. The hack is therefore only
+ * applied on open(), and not on resume() where it logically
+ * would be equally necessary. So we define open() as the only
+ * driver <-> device "syncronization point". Should we happen
+ * to lose a notification after open(), then syncronization
+ * will be lost until release()
+ *
+ * The hack should not be enabled for CDC WDM devices
+ * conforming to the CDC-WMC r1.1 specification. This is
+ * ensured by setting drain_on_open to false in wdm_probe().

- UTMI+ Low Pin Interface (ULPI) is specification for a commonly used
- USB 2.0 PHY interface. The ULPI specification defines a standard set
- of registers that can be used to detect the vendor and product which
- allows ULPI to be handled as a bus. This module is the driver for that
- bus.
-
- The ULPI interfaces (the buses) are registered by the drivers for USB
- controllers which support ULPI register access and have ULPI PHY
- attached to them. The ULPI PHY drivers themselves are normal PHY
- drivers.
-
- ULPI PHYs provide often functions such as ADP sensing/probing (OTG
- protocol) and USB charger detection.
-
- To compile this driver as a module, choose M here: the module will
- be called ulpi.
+ This driver allows LEDs to be controlled by USB events. Enabling this
+ trigger allows specifying list of USB ports that should turn on LED
+ when some USB device gets connected.

+ * Per-AG Block Reservations
+ *
+ * For some kinds of allocation group metadata structures, it is advantageous
+ * to reserve a small number of blocks in each AG so that future expansions of
+ * that data structure do not encounter ENOSPC because errors during a btree
+ * split cause the filesystem to go offline.
+ *
+ * Prior to the introduction of reflink, this wasn't an issue because the free
+ * space btrees maintain a reserve of space (the AGFL) to handle any expansion
+ * that may be necessary; and allocations of other metadata (inodes, BMBT,
+ * dir/attr) aren't restricted to a single AG. However, with reflink it is
+ * possible to allocate all the space in an AG, have subsequent reflink/CoW
+ * activity expand the refcount btree, and discover that there's no space left
+ * to handle that expansion. Since we can calculate the maximum size of the
+ * refcount btree, we can reserve space for it and avoid ENOSPC.
+ *
+ * Handling per-AG reservations consists of three changes to the allocator's
+ * behavior: First, because these reservations are always needed, we decrease
+ * the ag_max_usable counter to reflect the size of the AG after the reserved
+ * blocks are taken. Second, the reservations must be reflected in the
+ * fdblocks count to maintain proper accounting. Third, each AG must maintain
+ * its own reserved block counter so that we can calculate the amount of space
+ * that must remain free to maintain the reservations. Fourth, the "remaining
+ * reserved blocks" count must be used when calculating the length of the
+ * longest free extent in an AG and to clamp maxlen in the per-AG allocation
+ * functions. In other words, we maintain a virtual allocation via in-core
+ * accounting tricks so that we don't have to clean up after a crash. :)
+ *
+ * Reserved blocks can be managed by passing one of the enum xfs_ag_resv_type
+ * values via struct xfs_alloc_arg or directly to the xfs_free_extent
+ * function. It might seem a little funny to maintain a reservoir of blocks
+ * to feed another reservoir, but the AGFL only holds enough blocks to get
+ * through the next transaction. The per-AG reservation is to ensure (we
+ * hope) that each AG never runs out of blocks. Each data structure wanting
+ * to use the reservation system should update ask/used in xfs_ag_resv_init.

+ * Requesting a Fresh Transaction while Finishing Deferred Work
+ *
+ * If ->finish_item decides that it needs a fresh transaction to
+ * finish the work, it must ask its caller (xfs_defer_finish) for a
+ * continuation. The most likely cause of this circumstance are the
+ * refcount adjust functions deciding that they've logged enough items
+ * to be at risk of exceeding the transaction reservation.
+ *
+ * To get a fresh transaction, we want to log the existing log done
+ * item to prevent the log intent item from replaying, immediately log
+ * a new log intent item with the unfinished work items, roll the
+ * transaction, and re-call ->finish_item wherever it left off. The
+ * log done item and the new log intent item must be in the same
+ * transaction or atomicity cannot be guaranteed; defer_finish ensures
+ * that this happens.
+ *
+ * This requires some coordination between ->finish_item and
+ * defer_finish. Upon deciding to request a new transaction,
+ * ->finish_item should update the current work item to reflect the
+ * unfinished work. Next, it should reset the log done item's list
+ * count to the number of items finished, and return -EAGAIN.
+ * defer_finish sees the -EAGAIN, logs the new log intent item
+ * with the remaining work items, and leaves the xfs_defer_pending
+ * item at the head of the dop_work queue. Then it rolls the
+ * transaction and picks up processing where it left off. It is
+ * required that ->finish_item must be careful to leave enough
+ * transaction reservation to fit the new log intent item.

+ This tracer, when enabled will create one or more kernel threads,

+ hwlat_detector/width - time in usecs for how long to spin for
+ hwlat_detector/window - time in usecs between the start of each
+ iteration
+
+ A kernel thread is created that will spin with interrupts disabled
+ for "width" microseconds in every "widow" cycle. It will not spin
+ for "window - width" microseconds, where the system can
+ continue to operate.
+
+ The output will appear in the trace and trace_pipe files.
+
+ When the tracer is not running, it has no affect on the system,
+ but when it is running, it can cause the system to be

+ production system.
+
+ To enable this tracer, echo in "hwlat" into the current_tracer
+ file. Every time a latency is greater than tracing_thresh, it will

+ * trace_hwlatdetect.c - A simple Hardware Latency detector.
+ *
+ * Use this tracer to detect large system latencies induced by the behavior of
+ * certain underlying system hardware or firmware, independent of Linux itself.
+ * The code was developed originally to detect the presence of SMIs on Intel
+ * and AMD systems, although there is no dependency upon x86 herein.
+ *
+ * The classical example usage of this tracer is in detecting the presence of
+ * SMIs or System Management Interrupts on Intel and AMD systems. An SMI is a
+ * somewhat special form of hardware interrupt spawned from earlier CPU debug
+ * modes in which the (BIOS/EFI/etc.) firmware arranges for the South Bridge
+ * LPC (or other device) to generate a special interrupt under certain
+ * circumstances, for example, upon expiration of a special SMI timer device,
+ * due to certain external thermal readings, on certain I/O address accesses,
+ * and other situations. An SMI hits a special CPU pin, triggers a special
+ * SMI mode (complete with special memory map), and the OS is unaware.
+ *
+ * Although certain hardware-inducing latencies are necessary (for example,
+ * a modern system often requires an SMI handler for correct thermal control
+ * and remote management) they can wreak havoc upon any OS-level performance
+ * guarantees toward low-latency, especially when the OS is not even made
+ * aware of the presence of these interrupts. For this reason, we need a
+ * somewhat brute force mechanism to detect these interrupts. In this case,
+ * we do it by hogging all of the CPU(s) for configurable timer intervals,
+ * sampling the built-in CPU timer, looking for discontiguous readings.
+ *
+ * WARNING: This implementation necessarily introduces latencies. Therefore,
+ * you should NEVER use this tracer while running in a production
+ * environment requiring any kind of low-latency performance
+ * guarantee(s).

+# Here's how to use this:
+#
+# This script is used to help find functions that are being traced by function
+# tracer or function graph tracing that causes the machine to reboot, hang, or
+# crash. Here's the steps to take.
+#
+# First, determine if function tracing is working with a single function:
+#
+# (note, if this is a problem with function_graph tracing, then simply
+# replace "function" with "function_graph" in the following steps).
+#
+# # cd /sys/kernel/debug/tracing
+# # echo schedule > set_ftrace_filter
+# # echo function > current_tracer
+#
+# If this works, then we know that something is being traced that shouldn't be.
+#
+# # echo nop > current_tracer
+#
+# # cat available_filter_functions > ~/full-file
+# # ftrace-bisect ~/full-file ~/test-file ~/non-test-file
+# # cat ~/test-file > set_ftrace_filter
+#
+# *** Note *** this will take several minutes. Setting multiple functions is
+# an O(n^2) operation, and we are dealing with thousands of functions. So go
+# have coffee, talk with your coworkers, read facebook. And eventually, this
+# operation will end.
+#
+# # echo function > current_tracer
+#
+# If it crashes, we know that ~/test-file has a bad function.
+#
+# Reboot back to test kernel.
+#
+# # cd /sys/kernel/debug/tracing
+# # mv ~/test-file ~/full-file
+#
+# If it didn't crash.
+#
+# # echo nop > current_tracer
+# # mv ~/non-test-file ~/full-file
+#
+# Get rid of the other test file from previous run (or save them off somewhere).
+# # rm -f ~/test-file ~/non-test-file
+#
+# And start again:
+#
+# # ftrace-bisect ~/full-file ~/test-file ~/non-test-file
+#
+# The good thing is, because this cuts the number of functions in ~/test-file
+# by half, the cat of it into set_ftrace_filter takes half as long each
+# iteration, so don't talk so much at the water cooler the second time.
+#
+# Eventually, if you did this correctly, you will get down to the problem
+# function, and all we need to do is to notrace it.
+#
+# The way to figure out if the problem function is bad, just do:
+#
+# # echo <problem-function> > set_ftrace_notrace
+# # echo > set_ftrace_filter
+# # echo function > current_tracer
+#
+# And if it doesn't crash, we are done.
+#
+# If it does crash, do this again (there's more than one problem function)
+# but you need to echo the problem function(s) into set_ftrace_notrace before
+# enabling function tracing in the above steps. Or if you can compile the
+# kernel, annotate the problem functions with "notrace" and start again.

-config SECURITY_SELINUX_POLICYDB_VERSION_MAX
- bool "NSA SELinux maximum supported policy format version"
- depends on SECURITY_SELINUX
- default n
- help
- This option enables the maximum policy format version supported
- by SELinux to be set to a particular value. This value is reported
- to userspace via /selinux/policyvers and used at policy load time.
- It can be adjusted downward to support legacy userland (init) that
- does not correctly handle kernels that support newer policy versions.
-
- Examples:
- For the Fedora Core 3 or 4 Linux distributions, enable this option
- and set the value via the next option. For Fedora Core 5 and later,
- do not enable this option.
-
- If you are unsure how to answer this question, answer N.

- help
- This option sets the value for the maximum policy format version
- supported by SELinux.
-
- Examples:
- For Fedora Core 3, use 18.
- For Fedora Core 4, use 19.
-
- If you are unsure how to answer this question, look for the
- policy format version supported by your policy toolchain, by
- running 'checkpolicy -V'. Or look at what policy you have
- installed under /etc/selinux/$SELINUXTYPE/policy, where
- SELINUXTYPE is defined in your /etc/selinux/config.

+Basic types (u8/u16/u32/u64/s8/s16/s32/s64) and hexadecimal integers (x8/x16/x32/x64) are integer types. Prefix 's' and 'u' means those types are signed and unsigned respectively, and 'x' means that is shown in hexadecimal format. Traced arguments are shown in decimal (sNN/uNN) or hex (xNN). You can also use 's' or 'u' to specify only signedness and leave its size auto-detected by perf probe. Moreover, you can use 'x' to explicitly specify to be shown in hexadecimal (the size is also auto-detected).
String type is a special type, which fetches a "null-terminated" string from kernel space. This means it will fail and store NULL if the string container has been paged out. You can specify 'string' type only for the local variable or structure member which is an array of or a pointer to 'char' or 'unsigned char' type.
Bitfield is another special type, which takes 3 parameters, bit-width, bit-offset, and container-size (usually 32). The syntax is;

+ (e.g. Intel PT or CoreSight).
+
+ - tracepoint filters
+
+ In the case of tracepoints, multiple '--filter' options are combined
using '&&'.
+ - address filters
+
+ A hardware trace PMU advertises its ability to accept a number of
+ address filters by specifying a non-zero value in
+ /sys/bus/event_source/devices/<pmu>/nr_addr_filters.
+
+ Address filters have the format:
+
+ filter|start|stop|tracestop <start> [/ <size>] [@<file name>]
+
+ Where:
+ - 'filter': defines a region that will be traced.
+ - 'start': defines an address at which tracing will begin.
+ - 'stop': defines an address at which tracing will stop.
+ - 'tracestop': defines a region in which tracing will stop.
+
+ <file name> is the name of the object file, <start> is the offset to the
+ code to trace in that file, and <size> is the size of the region to
+ trace. 'start' and 'stop' filters need not specify a <size>.
+
+ If no object file is specified then the kernel is assumed, in which case
+ the start address must be a current kernel memory address.
+
+ <start> can also be specified by providing the name of a symbol. If the
+ symbol name is not unique, it can be disambiguated by inserting #n where
+ 'n' selects the n'th symbol in address order. Alternately #0, #g or #G
+ select only a global symbol. <size> can also be specified by providing
+ the name of a symbol, in which case the size is calculated to the end
+ of that symbol. For 'filter' and 'tracestop' filters, if <size> is
+ omitted and <start> is a symbol, then the size is calculated to the end
+ of that symbol.
+
+ If <size> is omitted and <start> is '*', then the start and size will
+ be calculated from the first and last symbols, i.e. to trace the whole
+ file.
+
+ If symbol names (or '*') are provided, they must be surrounded by white
+ space.
+
+ The filter passed to the kernel is not necessarily the same as entered.
+ To see the filter that is passed, use the -v option.
+
+ The kernel may not be able to configure a trace region if it is not
+ within a single mapping. MMAP events (or /proc/<pid>/maps) can be
+ examined to determine if that is a possibility.
+
+ Multiple filters can be separated with space or comma.
