Merge branch 'kerneldoc2' into docs-next
So once upon a time I set out to fix the problem reported by Tobin wherein
a literal block within a kerneldoc comment would be corrupted in
processing. On the way, though, I got annoyed at the way I have to learn
how kernel-doc works from the beginning every time I tear into it.
As a result, seven of the following eight patches just get rid of some dead
code and reorganize the rest - mostly turning the 500-line process_file()
function into something a bit more rational. Sphinx output is unchanged
after these are applied. Then, at the end, there's a tweak to stop messing
with literal blocks.
If anybody was unaware that I've not done any serious Perl since the
1990's, they will certainly understand that fact now.

+A: Although LLVM IR generation and optimization try to stay architecture
+ independent, "-target <arch>" still has some impact on generated code:
+
+ - BPF program may recursively include header file(s) with file scope
+ inline assembly codes. The default target can handle this well,

+ - When compiled without -g, additional elf sections, e.g.,
+ .eh_frame and .rela.eh_frame, may be present in the object file
+ with default target, but not with bpf target.
+
+ - The default target may turn a C switch statement into a switch table
+ lookup and jump operation. Since the switch table is placed
+ in the global readonly section, the bpf program will fail to load.
+ The bpf target does not support switch table optimization.
+ The clang option "-fno-jump-tables" can be used to disable
+ switch table generation.
+
+ You should use default target when:
+
+ - Your program includes a header file, e.g., ptrace.h, which eventually
+ pulls in some header files containing file scope host assembly codes.
+ - You can add "-fno-jump-tables" to work around the switch table issue.
+
+ Otherwise, you can use bpf target.

+=============
+ID Allocation
+=============
+
+:Author: Matthew Wilcox
+
+Overview
+========
+
+A common problem to solve is allocating identifiers (IDs); generally
+small numbers which identify a thing. Examples include file descriptors,
+process IDs, packet identifiers in networking protocols, SCSI tags
+and device instance numbers. The IDR and the IDA provide a reasonable
+solution to the problem to avoid everybody inventing their own. The IDR
+provides the ability to map an ID to a pointer, while the IDA provides
+only ID allocation, and as a result is much more memory-efficient.
+
+IDR usage
+=========
+
+Start by initialising an IDR, either with :c:func:`DEFINE_IDR`
+for statically allocated IDRs or :c:func:`idr_init` for dynamically
+allocated IDRs.
+
+You can call :c:func:`idr_alloc` to allocate an unused ID. Look up
+the pointer you associated with the ID by calling :c:func:`idr_find`
+and free the ID by calling :c:func:`idr_remove`.
+
+If you need to change the pointer associated with an ID, you can call
+:c:func:`idr_replace`. One common reason to do this is to reserve an
+ID by passing a ``NULL`` pointer to the allocation function; initialise the
+object with the reserved ID and finally insert the initialised object
+into the IDR.
+
+Some users need to allocate IDs larger than ``INT_MAX``. So far all of
+these users have been content with a ``UINT_MAX`` limit, and they use
+:c:func:`idr_alloc_u32`. If you need IDs that will not fit in a u32,
+we will work with you to address your needs.
+
+If you need to allocate IDs sequentially, you can use
+:c:func:`idr_alloc_cyclic`. The IDR becomes less efficient when dealing
+with larger IDs, so using this function comes at a slight cost.
+
+To perform an action on all pointers used by the IDR, you can
+either use the callback-based :c:func:`idr_for_each` or the
+iterator-style :c:func:`idr_for_each_entry`. You may need to use
+:c:func:`idr_for_each_entry_continue` to continue an iteration. You can
+also use :c:func:`idr_get_next` if the iterator doesn't fit your needs.
+
+When you have finished using an IDR, you can call :c:func:`idr_destroy`
+to release the memory used by the IDR. This will not free the objects
+pointed to from the IDR; if you want to do that, use one of the iterators
+to do it.
+
+You can use :c:func:`idr_is_empty` to find out whether there are any
+IDs currently allocated.
+
+If you need to take a lock while allocating a new ID from the IDR,
+you may need to pass a restrictive set of GFP flags, which can lead
+to the IDR being unable to allocate memory. To work around this,
+you can call :c:func:`idr_preload` before taking the lock, and then
+:c:func:`idr_preload_end` after the allocation.

+* Omnivision OV7740 CMOS image sensor
+
+The Omnivision OV7740 image sensor supports multiple output image
+size, such as VGA, and QVGA, CIF and any size smaller. It also
+supports the RAW RGB and YUV output formats.
+
+The common video interfaces bindings (see video-interfaces.txt) should
+be used to specify link to the image data receiver. The OV7740 device
+node should contain one 'port' child node with an 'endpoint' subnode.
+
+Required Properties:
+- compatible: "ovti,ov7740".
+- reg: I2C slave address of the sensor.
+- clocks: Reference to the xvclk input clock.
+- clock-names: "xvclk".
+
+Optional Properties:
+- reset-gpios: Rreference to the GPIO connected to the reset_b pin,
+ if any. Active low with pull-ip resistor.
+- powerdown-gpios: Reference to the GPIO connected to the pwdn pin,
+ if any. Active high with pull-down resistor.
+
+Endpoint node mandatory properties:
+- remote-endpoint: A phandle to the bus receiver's endpoint node.
+
+Example:
+
+ i2c1: i2c@fc028000 {
+ ov7740: camera@21 {
+ compatible = "ovti,ov7740";
+ reg = <0x21>;

-Including kernel-doc comments
-=============================
-
-The Linux kernel source files may contain structured documentation comments, or
-kernel-doc comments to describe the functions and types and design of the
-code. The documentation comments may be included to any of the reStructuredText
-documents using a dedicated kernel-doc Sphinx directive extension.
-
-The kernel-doc directive is of the format::
-
- .. kernel-doc:: source
- :option:
-
-The *source* is the path to a source file, relative to the kernel source
-tree. The following directive options are supported:
-
-export: *[source-pattern ...]*
- Include documentation for all functions in *source* that have been exported
- using ``EXPORT_SYMBOL`` or ``EXPORT_SYMBOL_GPL`` either in *source* or in any
- of the files specified by *source-pattern*.
-
- The *source-pattern* is useful when the kernel-doc comments have been placed
- in header files, while ``EXPORT_SYMBOL`` and ``EXPORT_SYMBOL_GPL`` are next to
- the function definitions.
-
- Examples::
-
- .. kernel-doc:: lib/bitmap.c
- :export:
-
- .. kernel-doc:: include/net/mac80211.h
- :export: net/mac80211/*.c
-
-internal: *[source-pattern ...]*
- Include documentation for all functions and types in *source* that have
- **not** been exported using ``EXPORT_SYMBOL`` or ``EXPORT_SYMBOL_GPL`` either
- in *source* or in any of the files specified by *source-pattern*.
-
- Example::
-
- .. kernel-doc:: drivers/gpu/drm/i915/intel_audio.c
- :internal:
-
-doc: *title*
- Include documentation for the ``DOC:`` paragraph identified by *title* in
- *source*. Spaces are allowed in *title*; do not quote the *title*. The *title*
- is only used as an identifier for the paragraph, and is not included in the
- output. Please make sure to have an appropriate heading in the enclosing
- reStructuredText document.
-
- Example::
-
- .. kernel-doc:: drivers/gpu/drm/i915/intel_audio.c
- :doc: High Definition Audio over HDMI and Display Port
-
-functions: *function* *[...]*
- Include documentation for each *function* in *source*.
-
- Example::
-
- .. kernel-doc:: lib/bitmap.c
- :functions: bitmap_parselist bitmap_parselist_user
-
-Without options, the kernel-doc directive includes all documentation comments
-from the source file.
-
-The kernel-doc extension is included in the kernel source tree, at
-``Documentation/sphinx/kerneldoc.py``. Internally, it uses the
-``scripts/kernel-doc`` script to extract the documentation comments from the
-source.

Writing kernel-doc comments
===========================
-In order to provide embedded, "C" friendly, easy to maintain, but consistent and
-extractable overview, function and type documentation, the Linux kernel has
-adopted a consistent style for documentation comments. The format for this
-documentation is called the kernel-doc format, described below. This style
-embeds the documentation within the source files, using a few simple conventions
-for adding documentation paragraphs and documenting functions and their
-parameters, structures and unions and their members, enumerations, and typedefs.
+The Linux kernel source files may contain structured documentation
+comments in the kernel-doc format to describe the functions, types
+and design of the code. It is easier to keep documentation up-to-date
+when it is embedded in source files.
-.. note:: The kernel-doc format is deceptively similar to gtk-doc or Doxygen,
- yet distinctively different, for historical reasons. The kernel source
- contains tens of thousands of kernel-doc comments. Please stick to the style
- described here.
+.. note:: The kernel-doc format is deceptively similar to javadoc,
+ gtk-doc or Doxygen, yet distinctively different, for historical
+ reasons. The kernel source contains tens of thousands of kernel-doc
+ comments. Please stick to the style described here.
-The ``scripts/kernel-doc`` script is used by the Sphinx kernel-doc extension in
-the documentation build to extract this embedded documentation into the various
-HTML, PDF, and other format documents.
+The kernel-doc structure is extracted from the comments, and proper
+`Sphinx C Domain`_ function and type descriptions with anchors are
+generated from them. The descriptions are filtered for special kernel-doc
+highlights and cross-references. See below for details.
-In order to provide good documentation of kernel functions and data structures,
-please use the following conventions to format your kernel-doc comments in the
-Linux kernel source.
+.. _Sphinx C Domain: http://www.sphinx-doc.org/en/stable/domains.html
+
+Every function that is exported to loadable modules using
+``EXPORT_SYMBOL`` or ``EXPORT_SYMBOL_GPL`` should have a kernel-doc
+comment. Functions and data structures in header files which are intended
+to be used by modules should also have kernel-doc comments.
+
+It is good practice to also provide kernel-doc formatted documentation
+for functions externally visible to other kernel files (not marked
+``static``). We also recommend providing kernel-doc formatted
+documentation for private (file ``static``) routines, for consistency of
+kernel source code layout. This is lower priority and at the discretion
+of the maintainer of that kernel source file.
How to format kernel-doc comments
---------------------------------
-The opening comment mark ``/**`` is reserved for kernel-doc comments. Only
-comments so marked will be considered by the ``kernel-doc`` tool. Use it only
-for comment blocks that contain kernel-doc formatted comments. The usual ``*/``
-should be used as the closing comment marker. The lines in between should be
-prefixed by `` * `` (space star space).
+The opening comment mark ``/**`` is used for kernel-doc comments. The
+``kernel-doc`` tool will extract comments marked this way. The rest of
+the comment is formatted like a normal multi-line comment with a column
+of asterisks on the left side, closing with ``*/`` on a line by itself.
-The function and type kernel-doc comments should be placed just before the
-function or type being described. The overview kernel-doc comments may be freely
-placed at the top indentation level.
-
-Example kernel-doc function comment::
-
- /**
- * foobar() - Brief description of foobar.
- * @argument1: Description of parameter argument1 of foobar.
- * @argument2: Description of parameter argument2 of foobar.
- *
- * Longer description of foobar.
- *
- * Return: Description of return value of foobar.
- */
- int foobar(int argument1, char *argument2)
-
-The format is similar for documentation for structures, enums, paragraphs,
-etc. See the sections below for specific details of each type.
-
-The kernel-doc structure is extracted from the comments, and proper `Sphinx C
-Domain`_ function and type descriptions with anchors are generated for them. The
-descriptions are filtered for special kernel-doc highlights and
-cross-references. See below for details.
-
-.. _Sphinx C Domain: http://www.sphinx-doc.org/en/stable/domains.html
-
-
-Parameters and member arguments
--------------------------------
-
-The kernel-doc function comments describe each parameter to the function and
-function typedefs or each member of struct/union, in order, with the
-``@argument:`` descriptions. For each non-private member argument, one
-``@argument`` definition is needed.
-
-The ``@argument:`` descriptions begin on the very next line following
-the opening brief function description line, with no intervening blank
-comment lines.
-
-The ``@argument:`` descriptions may span multiple lines.
-
-.. note::
-
- If the ``@argument`` description has multiple lines, the continuation
- of the description should be starting exactly at the same column as
- the previous line, e. g.::
-
- * @argument: some long description
- * that continues on next lines
-
- or::
-
- * @argument:
- * some long description
- * that continues on next lines
-
-If a function or typedef parameter argument is ``...`` (e. g. a variable
-number of arguments), its description should be listed in kernel-doc
-notation as::
-
- * @...: description
-
-Private members
-~~~~~~~~~~~~~~~
-
-Inside a struct or union description, you can use the ``private:`` and
-``public:`` comment tags. Structure fields that are inside a ``private:``
-area are not listed in the generated output documentation.
-
-The ``private:`` and ``public:`` tags must begin immediately following a
-``/*`` comment marker. They may optionally include comments between the
-``:`` and the ending ``*/`` marker.
-
-Example::
-
- /**
- * struct my_struct - short description
- * @a: first member
- * @b: second member
- * @d: fourth member
- *
- * Longer description
- */
- struct my_struct {
- int a;
- int b;
- /* private: internal use only */
- int c;
- /* public: the next one is public */
- int d;
- };
+The function and type kernel-doc comments should be placed just before
+the function or type being described in order to maximise the chance
+that somebody changing the code will also change the documentation. The
+overview kernel-doc comments may be placed anywhere at the top indentation
+level.

+match the origin file handle that was stored at copy_up time. If a
+found lower directory does not match the stored origin, that directory
+will not be merged with the upper directory.
+
+
+
+NFS export
+----------
+
+When the underlying filesystems supports NFS export and the "nfs_export"
+feature is enabled, an overlay filesystem may be exported to NFS.
+
+With the "nfs_export" feature, on copy_up of any lower object, an index
+entry is created under the index directory. The index entry name is the
+hexadecimal representation of the copy up origin file handle. For a
+non-directory object, the index entry is a hard link to the upper inode.
+For a directory object, the index entry has an extended attribute
+"trusted.overlay.upper" with an encoded file handle of the upper
+directory inode.
+
+When encoding a file handle from an overlay filesystem object, the
+following rules apply:
+
+1. For a non-upper object, encode a lower file handle from lower inode
+2. For an indexed object, encode a lower file handle from copy_up origin
+3. For a pure-upper object and for an existing non-indexed upper object,
+ encode an upper file handle from upper inode
+
+The encoded overlay file handle includes:
+ - Header including path type information (e.g. lower/upper)
+ - UUID of the underlying filesystem
+ - Underlying filesystem encoding of underlying inode
+
+This encoding format is identical to the encoding format file handles that
+are stored in extended attribute "trusted.overlay.origin".
+
+When decoding an overlay file handle, the following steps are followed:
+
+1. Find underlying layer by UUID and path type information.
+2. Decode the underlying filesystem file handle to underlying dentry.
+3. For a lower file handle, lookup the handle in index directory by name.
+4. If a whiteout is found in index, return ESTALE. This represents an
+ overlay object that was deleted after its file handle was encoded.
+5. For a non-directory, instantiate a disconnected overlay dentry from the
+ decoded underlying dentry, the path type and index inode, if found.
+6. For a directory, use the connected underlying decoded dentry, path type
+ and index, to lookup a connected overlay dentry.
+
+Decoding a non-directory file handle may return a disconnected dentry.
+copy_up of that disconnected dentry will create an upper index entry with
+no upper alias.
+
+When overlay filesystem has multiple lower layers, a middle layer
+directory may have a "redirect" to lower directory. Because middle layer
+"redirects" are not indexed, a lower file handle that was encoded from the
+"redirect" origin directory, cannot be used to find the middle or upper
+layer directory. Similarly, a lower file handle that was encoded from a
+descendant of the "redirect" origin directory, cannot be used to
+reconstruct a connected overlay path. To mitigate the cases of
+directories that cannot be decoded from a lower file handle, these
+directories are copied up on encode and encoded as an upper file handle.
+On an overlay filesystem with no upper layer this mitigation cannot be
+used NFS export in this setup requires turning off redirect follow (e.g.
+"redirect_dir=nofollow").
+
+The overlay filesystem does not support non-directory connectable file
+handles, so exporting with the 'subtree_check' exportfs configuration will
+cause failures to lookup files over NFS.
+
+When the NFS export feature is enabled, all directory index entries are
+verified on mount time to check that upper file handles are not stale.
+This verification may cause significant overhead in some cases.

Remote Controller core
~~~~~~~~~~~~~~~~~~~~~~
+The remote controller core implements infrastructure to receive and send
+remote controller keyboard keystrokes and mouse events.
+
+Every time a key is pressed on a remote controller, a scan code is produced.
+Also, on most hardware, keeping a key pressed for more than a few dozens of
+milliseconds produce a repeat key event. That's somewhat similar to what
+a normal keyboard or mouse is handled internally on Linux\ [#f1]_. So, the
+remote controller core is implemented on the top of the linux input/evdev
+interface.
+
+.. [#f1]
+
+ The main difference is that, on keyboard events, the keyboard controller
+ produces one event for a key press and another one for key release. On
+ infrared-based remote controllers, there's no key release event. Instead,
+ an extra code is produced to indicate key repeats.
+
+However, most of the remote controllers use infrared (IR) to transmit signals.
+As there are several protocols used to modulate infrared signals, one
+important part of the core is dedicated to adjust the driver and the core
+system to support the infrared protocol used by the emitter.
+
+The infrared transmission is done by blinking a infrared emitter using a
+carrier. The carrier can be switched on or off by the IR transmitter
+hardware. When the carrier is switched on, it is called *PULSE*.
+When the carrier is switched off, it is called *SPACE*.
+
+In other words, a typical IR transmission can be viewed as a sequence of
+*PULSE* and *SPACE* events, each with a given duration.
+
+The carrier parameters (frequency, duty cycle) and the intervals for
+*PULSE* and *SPACE* events depend on the protocol.
+For example, the NEC protocol uses a carrier of 38kHz, and transmissions
+start with a 9ms *PULSE* and a 4.5ms SPACE. It then transmits 16 bits of
+scan code, being 8 bits for address (usually it is a fixed number for a
+given remote controller), followed by 8 bits of code. A bit "1" is modulated
+with 560µs *PULSE* followed by 1690µs *SPACE* and a bit "0" is modulated
+with 560µs *PULSE* followed by 560µs *SPACE*.
+
+At receiver, a simple low-pass filter can be used to convert the received
+signal in a sequence of *PULSE/SPACE* events, filtering out the carrier
+frequency. Due to that, the receiver doesn't care about the carrier's
+actual frequency parameters: all it has to do is to measure the amount
+of time it receives *PULSE/SPACE* events.
+So, a simple IR receiver hardware will just provide a sequence of timings
+for those events to the Kernel. The drivers for hardware with such kind of
+receivers are identified by ``RC_DRIVER_IR_RAW``, as defined by
+:c:type:`rc_driver_type`\ [#f2]_. Other hardware come with a
+microcontroller that decode the *PULSE/SPACE* sequence and return scan
+codes to the Kernel. Such kind of receivers are identified
+by ``RC_DRIVER_SCANCODE``.
+
+.. [#f2]
+
+ The RC core also supports devices that have just IR emitters,
+ without any receivers. Right now, all such devices work only in
+ raw TX mode. Such kind of hardware is identified as
+ ``RC_DRIVER_IR_RAW_TX``.
+
+When the RC core receives events produced by ``RC_DRIVER_IR_RAW`` IR
+receivers, it needs to decode the IR protocol, in order to obtain the
+corresponding scan code. The protocols supported by the RC core are
+defined at enum :c:type:`rc_proto`.
+
+When the RC code receives a scan code (either directly, by a driver
+of the type ``RC_DRIVER_SCANCODE``, or via its IR decoders), it needs
+to convert into a Linux input event code. This is done via a mapping
+table.
+
+The Kernel has support for mapping tables available on most media
+devices. It also supports loading a table in runtime, via some
+sysfs nodes. See the :ref:`RC userspace API <Remote_controllers_Intro>`
+for more details.

The V4L2 events provide a generic way to pass events to user space.
The driver must use :c:type:`v4l2_fh` to be able to support V4L2 events.
-Events are defined by a type and an optional ID. The ID may refer to a V4L2
-object such as a control ID. If unused, then the ID is 0.
+Events are subscribed per-filehandle. An event specification consists of a
+``type`` and is optionally associated with an object identified through the
+``id`` field. If unused, then the ``id`` is 0. So an event is uniquely
+identified by the ``(type, id)`` tuple.
-When the user subscribes to an event the driver will allocate a number of
-kevent structs for that event. So every (type, ID) event tuple will have
-its own set of kevent structs. This guarantees that if a driver is generating
-lots of events of one type in a short time, then that will not overwrite
-events of another type.
+The :c:type:`v4l2_fh` struct has a list of subscribed events on its
+``subscribed`` field.
-But if you get more events of one type than the number of kevents that were
-reserved, then the oldest event will be dropped and the new one added.
+When the user subscribes to an event, a :c:type:`v4l2_subscribed_event`
+struct is added to :c:type:`v4l2_fh`\ ``.subscribed``, one for every
+subscribed event.
+
+Each :c:type:`v4l2_subscribed_event` struct ends with a
+:c:type:`v4l2_kevent` ringbuffer, with the size given by the caller
+of :c:func:`v4l2_event_subscribe`. This ringbuffer is used to store any events
+raised by the driver.
+
+So every ``(type, ID)`` event tuple will have its own
+:c:type:`v4l2_kevent` ringbuffer. This guarantees that if a driver is
+generating lots of events of one type in a short time, then that will
+not overwrite events of another type.
+
+But if you get more events of one type than the size of the
+:c:type:`v4l2_kevent` ringbuffer, then the oldest event will be dropped
+and the new one added.
+
+The :c:type:`v4l2_kevent` struct links into the ``available``
+list of the :c:type:`v4l2_fh` struct so :ref:`VIDIOC_DQEVENT` will
+know which event to dequeue first.
+
+Finally, if the event subscription is associated with a particular object
+such as a V4L2 control, then that object needs to know about that as well
+so that an event can be raised by that object. So the ``node`` field can
+be used to link the :c:type:`v4l2_subscribed_event` struct into a list of
+such objects.
+
+So to summarize:
+
+- struct :c:type:`v4l2_fh` has two lists: one of the ``subscribed`` events,
+ and one of the ``available`` events.
+
+- struct :c:type:`v4l2_subscribed_event` has a ringbuffer of raised
+ (pending) events of that particular type.
+
+- If struct :c:type:`v4l2_subscribed_event` is associated with a specific
+ object, then that object will have an internal list of
+ struct :c:type:`v4l2_subscribed_event` so it knows who subscribed an
+ event to that object.
Furthermore, the internal struct :c:type:`v4l2_subscribed_event` has
``merge()`` and ``replace()`` callbacks which drivers can set. These
callbacks are called when a new event is raised and there is no more room.
+
The ``replace()`` callback allows you to replace the payload of the old event
with that of the new event, merging any relevant data from the old payload
into the new payload that replaces it. It is called when this event type has
-only one kevent struct allocated. The ``merge()`` callback allows you to merge
-the oldest event payload into that of the second-oldest event payload. It is
-called when there are two or more kevent structs allocated.
+a ringbuffer with size is one, i.e. only one event can be stored in the
+ringbuffer.
+
+The ``merge()`` callback allows you to merge the oldest event payload into
+that of the second-oldest event payload. It is called when
+the ringbuffer has size is greater than one.
This way no status information is lost, just the intermediate steps leading
up to that state.

+
+``argp``
+ Pointer to struct :c:type:`dmx_exportbuffer`.
+
+
+Description
+===========
+
+This ioctl is an extension to the memory mapping I/O method.
+It can be used to export a buffer as a DMABUF file at any time after
+buffers have been allocated with the :ref:`DMX_REQBUFS` ioctl.
+
+To export a buffer, applications fill struct :c:type:`dmx_exportbuffer`.
+Applications must set the ``index`` field. Valid index numbers
+range from zero to the number of buffers allocated with :ref:`DMX_REQBUFS`
+(struct :c:type:`dmx_requestbuffers` ``count``) minus one.
+Additional flags may be posted in the ``flags`` field. Refer to a manual
+for open() for details. Currently only O_CLOEXEC, O_RDONLY, O_WRONLY,
+and O_RDWR are supported.
+All other fields must be set to zero. In the
+case of multi-planar API, every plane is exported separately using
+multiple :ref:`DMX_EXPBUF` calls.
+
+After calling :ref:`DMX_EXPBUF` the ``fd`` field will be set by a
+driver, on success. This is a DMABUF file descriptor. The application may
+pass it to other DMABUF-aware devices. It is recommended to close a DMABUF
+file when it is no longer used to allow the associated memory to be reclaimed.
+
+
+Examples
+========
+
+
+.. code-block:: c
+
+ int buffer_export(int v4lfd, enum dmx_buf_type bt, int index, int *dmafd)
+ {
+ struct dmx_exportbuffer expbuf;
+
+ memset(&expbuf, 0, sizeof(expbuf));
+ expbuf.type = bt;
+ expbuf.index = index;
+ if (ioctl(v4lfd, DMX_EXPBUF, &expbuf) == -1) {
+ perror("DMX_EXPBUF");
+ return -1;
+ }
+
+ *dmafd = expbuf.fd;
+
+ return 0;
+ }
+
+Return Value
+============
+
+On success 0 is returned, on error -1 and the ``errno`` variable is set
+appropriately. The generic error codes are described at the
+:ref:`Generic Error Codes <gen-errors>` chapter.
+
+EINVAL
+ A queue is not in MMAP mode or DMABUF exporting is not supported or
+ ``flags`` or ``index`` fields are invalid.

+
+
+.. c:function:: void *mmap( void *start, size_t length, int prot, int flags, int fd, off_t offset )
+ :name: dmx-mmap
+
+Arguments
+=========
+
+``start``
+ Map the buffer to this address in the application's address space.
+ When the ``MAP_FIXED`` flag is specified, ``start`` must be a
+ multiple of the pagesize and mmap will fail when the specified
+ address cannot be used. Use of this option is discouraged;
+ applications should just specify a ``NULL`` pointer here.
+
+``length``
+ Length of the memory area to map. This must be a multiple of the
+ DVB packet length (188, on most drivers).
+
+``prot``
+ The ``prot`` argument describes the desired memory protection.
+ Regardless of the device type and the direction of data exchange it
+ should be set to ``PROT_READ`` | ``PROT_WRITE``, permitting read
+ and write access to image buffers. Drivers should support at least
+ this combination of flags.
+
+``flags``
+ The ``flags`` parameter specifies the type of the mapped object,
+ mapping options and whether modifications made to the mapped copy of
+ the page are private to the process or are to be shared with other
+ references.
+
+ ``MAP_FIXED`` requests that the driver selects no other address than
+ the one specified. If the specified address cannot be used,
+ :ref:`mmap() <dmx-mmap>` will fail. If ``MAP_FIXED`` is specified,
+ ``start`` must be a multiple of the pagesize. Use of this option is
+ discouraged.
+
+ One of the ``MAP_SHARED`` or ``MAP_PRIVATE`` flags must be set.
+ ``MAP_SHARED`` allows applications to share the mapped memory with
+ other (e. g. child-) processes.
+
+ .. note::
+
+ The Linux Digital TV applications should not set the
+ ``MAP_PRIVATE``, ``MAP_DENYWRITE``, ``MAP_EXECUTABLE`` or ``MAP_ANON``
+ flags.
+
+``fd``
+ File descriptor returned by :ref:`open() <dmx_fopen>`.
+
+``offset``
+ Offset of the buffer in device memory, as returned by
+ :ref:`DMX_QUERYBUF` ioctl.
+
+
+Description
+===========
+
+The :ref:`mmap() <dmx-mmap>` function asks to map ``length`` bytes starting at
+``offset`` in the memory of the device specified by ``fd`` into the
+application address space, preferably at address ``start``. This latter
+address is a hint only, and is usually specified as 0.
+
+Suitable length and offset parameters are queried with the
+:ref:`DMX_QUERYBUF` ioctl. Buffers must be allocated with the
+:ref:`DMX_REQBUFS` ioctl before they can be queried.
+
+To unmap buffers the :ref:`munmap() <dmx-munmap>` function is used.
+
+
+Return Value
+============
+
+On success :ref:`mmap() <dmx-mmap>` returns a pointer to the mapped buffer. On
+error ``MAP_FAILED`` (-1) is returned, and the ``errno`` variable is set
+appropriately. Possible error codes are:
+
+EBADF
+ ``fd`` is not a valid file descriptor.
+
+EACCES
+ ``fd`` is not open for reading and writing.
+
+EINVAL
+ The ``start`` or ``length`` or ``offset`` are not suitable. (E. g.
+ they are too large, or not aligned on a ``PAGESIZE`` boundary.)
+
+ The ``flags`` or ``prot`` value is not supported.
+
+ No buffers have been allocated with the
+ :ref:`DMX_REQBUFS` ioctl.
+
+ENOMEM
+ Not enough physical or virtual memory was available to complete the
+ request.

+
+
+Description
+===========
+
+Applications call the ``DMX_QBUF`` ioctl to enqueue an empty
+(capturing) or filled (output) buffer in the driver's incoming queue.
+The semantics depend on the selected I/O method.
+
+To enqueue a buffer applications set the ``index`` field. Valid index
+numbers range from zero to the number of buffers allocated with
+:ref:`DMX_REQBUFS` (struct :c:type:`dmx_requestbuffers` ``count``) minus
+one. The contents of the struct :c:type:`dmx_buffer` returned
+by a :ref:`DMX_QUERYBUF` ioctl will do as well.
+
+When ``DMX_QBUF`` is called with a pointer to this structure, it locks the
+memory pages of the buffer in physical memory, so they cannot be swapped
+out to disk. Buffers remain locked until dequeued, until the
+the device is closed.
+
+Applications call the ``DMX_DQBUF`` ioctl to dequeue a filled
+(capturing) buffer from the driver's outgoing queue. They just set the ``reserved`` field array to zero. When ``DMX_DQBUF`` is called with a
+pointer to this structure, the driver fills the remaining fields or
+returns an error code.
+
+By default ``DMX_DQBUF`` blocks when no buffer is in the outgoing
+queue. When the ``O_NONBLOCK`` flag was given to the
+:ref:`open() <dmx_fopen>` function, ``DMX_DQBUF`` returns
+immediately with an ``EAGAIN`` error code when no buffer is available.
+
+The struct :c:type:`dmx_buffer` structure is specified in

+
+
+Return Value
+============
+
+On success 0 is returned, on error -1 and the ``errno`` variable is set

+
+EAGAIN
+ Non-blocking I/O has been selected using ``O_NONBLOCK`` and no
+ buffer was in the outgoing queue.
+
+EINVAL
+ The ``index`` is out of bounds, or no buffers have been allocated yet.
+
+EIO
+ ``DMX_DQBUF`` failed due to an internal error. Can also indicate
+ temporary problems like signal loss or CRC errors.

+
+Description
+===========
+
+This ioctl is used to initiate a memory mapped or DMABUF based demux I/O.
+
+Memory mapped buffers are located in device memory and must be allocated
+with this ioctl before they can be mapped into the application's address
+space. User buffers are allocated by applications themselves, and this
+ioctl is merely used to switch the driver into user pointer I/O mode and
+to setup some internal structures. Similarly, DMABUF buffers are
+allocated by applications through a device driver, and this ioctl only
+configures the driver into DMABUF I/O mode without performing any direct
+allocation.
+
+To allocate device buffers applications initialize all fields of the
+struct :c:type:`dmx_requestbuffers` structure. They set the ``count`` field
+to the desired number of buffers, and ``size`` to the size of each
+buffer.
+
+When the ioctl is called with a pointer to this structure, the driver will
+attempt to allocate the requested number of buffers and it stores the actual
+number allocated in the ``count`` field. The ``count`` can be smaller than the number requested, even zero, when the driver runs out of free memory. A larger
+number is also possible when the driver requires more buffers to
+function correctly. The actual allocated buffer size can is returned
+at ``size``, and can be smaller than what's requested.
+
+When this I/O method is not supported, the ioctl returns an ``EOPNOTSUPP``
+error code.
+
+Applications can call :ref:`DMX_REQBUFS` again to change the number of
+buffers, however this cannot succeed when any buffers are still mapped.
+A ``count`` value of zero frees all buffers, after aborting or finishing
+any DMA in progress.
+
+
+Return Value
+============
+
+On success 0 is returned, on error -1 and the ``errno`` variable is set
+appropriately. The generic error codes are described at the
+:ref:`Generic Error Codes <gen-errors>` chapter.

+EOPNOTSUPP

+
+ In the Sanyo and NEC protocol, if you hold a button on remote, rather than

+UVC Payload Header Data
+
+
+Description
+===========
+
+This format describes standard UVC metadata, extracted from UVC packet headers
+and provided by the UVC driver through metadata video nodes. That data includes
+exact copies of the standard part of UVC Payload Header contents and auxiliary
+timing information, required for precise interpretation of timestamps, contained
+in those headers. See section "2.4.3.3 Video and Still Image Payload Headers" of
+the "UVC 1.5 Class specification" for details.
+
+Each UVC payload header can be between 2 and 12 bytes large. Buffers can
+contain multiple headers, if multiple such headers have been transmitted by the
+camera for the respective frame. However, the driver may drop headers when the
+buffer is full, when they contain no useful information (e.g. those without the
+SCR field or with that field identical to the previous header), or generally to
+perform rate limiting when the device sends a large number of headers.
+
+Each individual block contains the following fields:
+
+.. flat-table:: UVC Metadata Block
+ :widths: 1 4
+ :header-rows: 1
+ :stub-columns: 0
+
+ * - Field

+ them
+ * - :cspan:`1` *The rest is an exact copy of the UVC payload header:*

+ - length of the rest of the block, including this field
+ * - __u8 flags;
+ - Flags, indicating presence of other standard UVC fields

+These four pixel formats are used by Intel IPU3 driver, they are raw
+sRGB / Bayer formats with 10 bits per sample with every 25 pixels packed
+to 32 bytes leaving 6 most significant bits padding in the last byte.
+The format is little endian.
+
+In other respects this format is similar to :ref:`V4L2-PIX-FMT-SRGGB10`.
+Below is an example of a small image in V4L2_PIX_FMT_IPU3_SBGGR10 format.

+
+===========================
+Kernel Maintainer PGP guide
+===========================
+
+:Author: Konstantin Ryabitsev <konstantin@linuxfoundation.org>
+
+This document is aimed at Linux kernel developers, and especially at
+subsystem maintainers. It contains a subset of information discussed in
+the more general "`Protecting Code Integrity`_" guide published by the
+Linux Foundation. Please read that document for more in-depth discussion
+on some of the topics mentioned in this guide.
+
+.. _`Protecting Code Integrity`: https://github.com/lfit/itpol/blob/master/protecting-code-integrity.md
+
+The role of PGP in Linux Kernel development
+===========================================
+
+PGP helps ensure the integrity of the code that is produced by the Linux
+kernel development community and, to a lesser degree, establish trusted
+communication channels between developers via PGP-signed email exchange.
+
+The Linux kernel source code is available in two main formats:
+
+- Distributed source repositories (git)
+- Periodic release snapshots (tarballs)
+
+Both git repositories and tarballs carry PGP signatures of the kernel
+developers who create official kernel releases. These signatures offer a
+cryptographic guarantee that downloadable versions made available via
+kernel.org or any other mirrors are identical to what these developers
+have on their workstations. To this end:
+
+- git repositories provide PGP signatures on all tags
+- tarballs provide detached PGP signatures with all downloads
+
+.. _devs_not_infra:
+
+Trusting the developers, not infrastructure
+-------------------------------------------
+
+Ever since the 2011 compromise of core kernel.org systems, the main
+operating principle of the Kernel Archives project has been to assume
+that any part of the infrastructure can be compromised at any time. For
+this reason, the administrators have taken deliberate steps to emphasize
+that trust must always be placed with developers and never with the code
+hosting infrastructure, regardless of how good the security practices
+for the latter may be.
+
+The above guiding principle is the reason why this guide is needed. We
+want to make sure that by placing trust into developers we do not simply
+shift the blame for potential future security incidents to someone else.
+The goal is to provide a set of guidelines developers can use to create
+a secure working environment and safeguard the PGP keys used to
+establish the integrity of the Linux kernel itself.
+
+.. _pgp_tools:
+
+PGP tools
+=========
+
+Use GnuPG v2
+------------
+
+Your distro should already have GnuPG installed by default, you just
+need to verify that you are using version 2.x and not the legacy 1.4
+release -- many distributions still package both, with the default
+``gpg`` command invoking GnuPG v.1. To check, run::
+
+ $ gpg --version | head -n1
+
+If you see ``gpg (GnuPG) 1.4.x``, then you are using GnuPG v.1. Try the
+``gpg2`` command (if you don't have it, you may need to install the
+gnupg2 package)::
+
+ $ gpg2 --version | head -n1
+
+If you see ``gpg (GnuPG) 2.x.x``, then you are good to go. This guide
+will assume you have the version 2.2 of GnuPG (or later). If you are
+using version 2.0 of GnuPG, then some of the commands in this guide will
+not work, and you should consider installing the latest 2.2 version of
+GnuPG. Versions of gnupg-2.1.11 and later should be compatible for the
+purposes of this guide as well.
+
+If you have both ``gpg`` and ``gpg2`` commands, you should make sure you
+are always using GnuPG v2, not the legacy version. You can enforce this
+by setting the appropriate alias::
+
+ $ alias gpg=gpg2
+
+You can put that in your ``.bashrc`` to make sure it's always the case.
+
+Configure gpg-agent options
+~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+The GnuPG agent is a helper tool that will start automatically whenever
+you use the ``gpg`` command and run in the background with the purpose
+of caching the private key passphrase. There are two options you should
+know in order to tweak when the passphrase should be expired from cache:
+
+- ``default-cache-ttl`` (seconds): If you use the same key again before
+ the time-to-live expires, the countdown will reset for another period.
+ The default is 600 (10 minutes).
+- ``max-cache-ttl`` (seconds): Regardless of how recently you've used
+ the key since initial passphrase entry, if the maximum time-to-live
+ countdown expires, you'll have to enter the passphrase again. The
+ default is 30 minutes.
+
+If you find either of these defaults too short (or too long), you can
+edit your ``~/.gnupg/gpg-agent.conf`` file to set your own values::
+
+ # set to 30 minutes for regular ttl, and 2 hours for max ttl
+ default-cache-ttl 1800
+ max-cache-ttl 7200
+
+.. note::
+
+ It is no longer necessary to start gpg-agent manually at the
+ beginning of your shell session. You may want to check your rc files
+ to remove anything you had in place for older versions of GnuPG, as
+ it may not be doing the right thing any more.
+
+Set up a refresh cronjob
+~~~~~~~~~~~~~~~~~~~~~~~~
+
+You will need to regularly refresh your keyring in order to get the
+latest changes on other people's public keys, which is best done with a
+daily cronjob::
+
+ @daily /usr/bin/gpg2 --refresh >/dev/null 2>&1
+
+Check the full path to your ``gpg`` or ``gpg2`` command and use the
+``gpg2`` command if regular ``gpg`` for you is the legacy GnuPG v.1.
+
+.. _master_key:
+
+Protect your master PGP key
+===========================
+
+This guide assumes that you already have a PGP key that you use for Linux
+kernel development purposes. If you do not yet have one, please see the
+"`Protecting Code Integrity`_" document mentioned earlier for guidance
+on how to create a new one.
+
+You should also make a new key if your current one is weaker than 2048 bits
+(RSA).
+
+Master key vs. Subkeys
+----------------------
+
+Subkeys are fully independent PGP keypairs that are tied to the "master"
+key using certifying key signatures (certificates). It is important to
+understand the following:
+
+1. There are no technical differences between the "master key" and "subkeys."
+2. At creation time, we assign functional limitations to each key by
+ giving it specific capabilities.
+3. A PGP key can have 4 capabilities:
+
+ - **[S]** key can be used for signing
+ - **[E]** key can be used for encryption
+ - **[A]** key can be used for authentication
+ - **[C]** key can be used for certifying other keys
+
+4. A single key may have multiple capabilities.
+5. A subkey is fully independent from the master key. A message
+ encrypted to a subkey cannot be decrypted with the master key. If you
+ lose your private subkey, it cannot be recreated from the master key
+ in any way.
+
+The key carrying the **[C]** (certify) capability is considered the
+"master" key because it is the only key that can be used to indicate
+relationship with other keys. Only the **[C]** key can be used to:
+
+- add or revoke other keys (subkeys) with S/E/A capabilities
+- add, change or revoke identities (uids) associated with the key
+- add or change the expiration date on itself or any subkey
+- sign other people's keys for web of trust purposes
+
+By default, GnuPG creates the following when generating new keys:
+
+- A master key carrying both Certify and Sign capabilities (**[SC]**)
+- A separate subkey with the Encryption capability (**[E]**)
+
+If you used the default parameters when generating your key, then that
+is what you will have. You can verify by running ``gpg --list-secret-keys``,
+for example::
+
+ sec rsa2048 2018-01-23 [SC] [expires: 2020-01-23]
+ 000000000000000000000000AAAABBBBCCCCDDDD
+ uid [ultimate] Alice Dev <adev@kernel.org>
+ ssb rsa2048 2018-01-23 [E] [expires: 2020-01-23]
+
+Any key carrying the **[C]** capability is your master key, regardless
+of any other capabilities it may have assigned to it.
+
+The long line under the ``sec`` entry is your key fingerprint --
+whenever you see ``[fpr]`` in the examples below, that 40-character
+string is what it refers to.
+
+Ensure your passphrase is strong
+--------------------------------
+
+GnuPG uses passphrases to encrypt your private keys before storing them on
+disk. This way, even if your ``.gnupg`` directory is leaked or stolen in
+its entirety, the attackers cannot use your private keys without first
+obtaining the passphrase to decrypt them.
+
+It is absolutely essential that your private keys are protected by a
+strong passphrase. To set it or change it, use::
+
+ $ gpg --change-passphrase [fpr]
+
+Create a separate Signing subkey
+--------------------------------
+
+Our goal is to protect your master key by moving it to offline media, so
+if you only have a combined **[SC]** key, then you should create a separate
+signing subkey::
+
+ $ gpg --quick-add-key [fpr] ed25519 sign
+
+Remember to tell the keyservers about this change, so others can pull down
+your new subkey::
+
+ $ gpg --send-key [fpr]
+
+.. note:: ECC support in GnuPG
+
+ GnuPG 2.1 and later has full support for Elliptic Curve
+ Cryptography, with ability to combine ECC subkeys with traditional
+ RSA master keys. The main upside of ECC cryptography is that it is
+ much faster computationally and creates much smaller signatures when
+ compared byte for byte with 2048+ bit RSA keys. Unless you plan on
+ using a smartcard device that does not support ECC operations, we
+ recommend that you create an ECC signing subkey for your kernel
+ work.
+
+ If for some reason you prefer to stay with RSA subkeys, just replace
+ "ed25519" with "rsa2048" in the above command.
+
+
+Back up your master key for disaster recovery
+---------------------------------------------
+
+The more signatures you have on your PGP key from other developers, the
+more reasons you have to create a backup version that lives on something
+other than digital media, for disaster recovery reasons.
+
+The best way to create a printable hardcopy of your private key is by
+using the ``paperkey`` software written for this very purpose. See ``man
+paperkey`` for more details on the output format and its benefits over
+other solutions. Paperkey should already be packaged for most
+distributions.
+
+Run the following command to create a hardcopy backup of your private
+key::
+
+ $ gpg --export-secret-key [fpr] | paperkey -o /tmp/key-backup.txt
+
+Print out that file (or pipe the output straight to lpr), then take a
+pen and write your passphrase on the margin of the paper. **This is
+strongly recommended** because the key printout is still encrypted with
+that passphrase, and if you ever change it you will not remember what it
+used to be when you had created the backup -- *guaranteed*.
+
+Put the resulting printout and the hand-written passphrase into an envelope
+and store in a secure and well-protected place, preferably away from your
+home, such as your bank vault.
+
+.. note::
+
+ Your printer is probably no longer a simple dumb device connected to
+ your parallel port, but since the output is still encrypted with
+ your passphrase, printing out even to "cloud-integrated" modern
+ printers should remain a relatively safe operation. One option is to
+ change the passphrase on your master key immediately after you are
+ done with paperkey.
+
+Back up your whole GnuPG directory
+----------------------------------
+
+.. warning::
+
+ **!!!Do not skip this step!!!**
+
+It is important to have a readily available backup of your PGP keys
+should you need to recover them. This is different from the
+disaster-level preparedness we did with ``paperkey``. You will also rely
+on these external copies whenever you need to use your Certify key --
+such as when making changes to your own key or signing other people's
+keys after conferences and summits.
+
+Start by getting a small USB "thumb" drive (preferably two!) that you
+will use for backup purposes. You will need to encrypt them using LUKS
+-- refer to your distro's documentation on how to accomplish this.
+
+For the encryption passphrase, you can use the same one as on your
+master key.
+
+Once the encryption process is over, re-insert the USB drive and make
+sure it gets properly mounted. Copy your entire ``.gnupg`` directory
+over to the encrypted storage::
+
+ $ cp -a ~/.gnupg /media/disk/foo/gnupg-backup
+
+You should now test to make sure everything still works::
+
+ $ gpg --homedir=/media/disk/foo/gnupg-backup --list-key [fpr]
+
+If you don't get any errors, then you should be good to go. Unmount the
+USB drive, distinctly label it so you don't blow it away next time you
+need to use a random USB drive, and put in a safe place -- but not too
+far away, because you'll need to use it every now and again for things
+like editing identities, adding or revoking subkeys, or signing other
+people's keys.
+
+Remove the master key from your homedir
+----------------------------------------
+
+The files in our home directory are not as well protected as we like to
+think. They can be leaked or stolen via many different means:
+
+- by accident when making quick homedir copies to set up a new workstation
+- by systems administrator negligence or malice
+- via poorly secured backups
+- via malware in desktop apps (browsers, pdf viewers, etc)
+- via coercion when crossing international borders
+
+Protecting your key with a good passphrase greatly helps reduce the risk
+of any of the above, but passphrases can be discovered via keyloggers,
+shoulder-surfing, or any number of other means. For this reason, the
+recommended setup is to remove your master key from your home directory
+and store it on offline storage.
+
+.. warning::
+
+ Please see the previous section and make sure you have backed up
+ your GnuPG directory in its entirety. What we are about to do will
+ render your key useless if you do not have a usable backup!
+
+First, identify the keygrip of your master key::
+
+ $ gpg --with-keygrip --list-key [fpr]
+
+The output will be something like this::
+
+ pub rsa2048 2018-01-24 [SC] [expires: 2020-01-24]
+ 000000000000000000000000AAAABBBBCCCCDDDD
+ Keygrip = 1111000000000000000000000000000000000000
+ uid [ultimate] Alice Dev <adev@kernel.org>
+ sub rsa2048 2018-01-24 [E] [expires: 2020-01-24]
+ Keygrip = 2222000000000000000000000000000000000000
+ sub ed25519 2018-01-24 [S]
+ Keygrip = 3333000000000000000000000000000000000000
+
+Find the keygrip entry that is beneath the ``pub`` line (right under the
+master key fingerprint). This will correspond directly to a file in your
+``~/.gnupg`` directory::
+
+ $ cd ~/.gnupg/private-keys-v1.d
+ $ ls
+ 1111000000000000000000000000000000000000.key
+ 2222000000000000000000000000000000000000.key
+ 3333000000000000000000000000000000000000.key
+
+All you have to do is simply remove the .key file that corresponds to
+the master keygrip::
+
+ $ cd ~/.gnupg/private-keys-v1.d
+ $ rm 1111000000000000000000000000000000000000.key
+
+Now, if you issue the ``--list-secret-keys`` command, it will show that
+the master key is missing (the ``#`` indicates it is not available)::
+
+ $ gpg --list-secret-keys
+ sec# rsa2048 2018-01-24 [SC] [expires: 2020-01-24]
+ 000000000000000000000000AAAABBBBCCCCDDDD
+ uid [ultimate] Alice Dev <adev@kernel.org>
+ ssb rsa2048 2018-01-24 [E] [expires: 2020-01-24]
+ ssb ed25519 2018-01-24 [S]
+
+You should also remove any ``secring.gpg`` files in the ``~/.gnupg``
+directory, which are left over from earlier versions of GnuPG.
+
+If you don't have the "private-keys-v1.d" directory
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+If you do not have a ``~/.gnupg/private-keys-v1.d`` directory, then your
+secret keys are still stored in the legacy ``secring.gpg`` file used by
+GnuPG v1. Making any changes to your key, such as changing the
+passphrase or adding a subkey, should automatically convert the old
+``secring.gpg`` format to use ``private-keys-v1.d`` instead.
+
+Once you get that done, make sure to delete the obsolete ``secring.gpg``
+file, which still contains your private keys.
+
+.. _smartcards:
+
+Move the subkeys to a dedicated crypto device
+=============================================
+
+Even though the master key is now safe from being leaked or stolen, the
+subkeys are still in your home directory. Anyone who manages to get
+their hands on those will be able to decrypt your communication or fake
+your signatures (if they know the passphrase). Furthermore, each time a
+GnuPG operation is performed, the keys are loaded into system memory and
+can be stolen from there by sufficiently advanced malware (think
+Meltdown and Spectre).
+
+The best way to completely protect your keys is to move them to a
+specialized hardware device that is capable of smartcard operations.
+
+The benefits of smartcards
+--------------------------
+
+A smartcard contains a cryptographic chip that is capable of storing
+private keys and performing crypto operations directly on the card
+itself. Because the key contents never leave the smartcard, the
+operating system of the computer into which you plug in the hardware
+device is not able to retrieve the private keys themselves. This is very
+different from the encrypted USB storage device we used earlier for
+backup purposes -- while that USB device is plugged in and mounted, the
+operating system is able to access the private key contents.
+
+Using external encrypted USB media is not a substitute to having a
+smartcard-capable device.
+
+Available smartcard devices
+---------------------------
+
+Unless all your laptops and workstations have smartcard readers, the
+easiest is to get a specialized USB device that implements smartcard
+functionality. There are several options available:
+
+- `Nitrokey Start`_: Open hardware and Free Software, based on FSI
+ Japan's `Gnuk`_. Offers support for ECC keys, but fewest security
+ features (such as resistance to tampering or some side-channel
+ attacks).
+- `Nitrokey Pro`_: Similar to the Nitrokey Start, but more
+ tamper-resistant and offers more security features, but no ECC
+ support.
+- `Yubikey 4`_: proprietary hardware and software, but cheaper than
+ Nitrokey Pro and comes available in the USB-C form that is more useful
+ with newer laptops. Offers additional security features such as FIDO
+ U2F, but no ECC.
+
+`LWN has a good review`_ of some of the above models, as well as several
+others. If you want to use ECC keys, your best bet among commercially
+available devices is the Nitrokey Start.

+
+Configure your smartcard device
+-------------------------------
+
+Your smartcard device should Just Work (TM) the moment you plug it into
+any modern Linux workstation. You can verify it by running::
+
+ $ gpg --card-status
+
+If you see full smartcard details, then you are good to go.
+Unfortunately, troubleshooting all possible reasons why things may not
+be working for you is way beyond the scope of this guide. If you are
+having trouble getting the card to work with GnuPG, please seek help via
+usual support channels.
+
+To configure your smartcard, you will need to use the GnuPG menu system, as
+there are no convenient command-line switches::
+
+ $ gpg --card-edit
+ [...omitted...]
+ gpg/card> admin
+ Admin commands are allowed
+ gpg/card> passwd
+
+You should set the user PIN (1), Admin PIN (3), and the Reset Code (4).
+Please make sure to record and store these in a safe place -- especially
+the Admin PIN and the Reset Code (which allows you to completely wipe
+the smartcard). You so rarely need to use the Admin PIN, that you will
+inevitably forget what it is if you do not record it.
+
+Getting back to the main card menu, you can also set other values (such
+as name, sex, login data, etc), but it's not necessary and will
+additionally leak information about your smartcard should you lose it.
+
+.. note::
+
+ Despite having the name "PIN", neither the user PIN nor the admin
+ PIN on the card need to be numbers.
+
+Move the subkeys to your smartcard
+----------------------------------
+
+Exit the card menu (using "q") and save all changes. Next, let's move
+your subkeys onto the smartcard. You will need both your PGP key
+passphrase and the admin PIN of the card for most operations::
+
+ $ gpg --edit-key [fpr]
+
+ Secret subkeys are available.
+
+ pub rsa2048/AAAABBBBCCCCDDDD

+
+ gpg>
+
+Using ``--edit-key`` puts us into the menu mode again, and you will
+notice that the key listing is a little different. From here on, all
+commands are done from inside this menu mode, as indicated by ``gpg>``.
+
+First, let's select the key we'll be putting onto the card -- you do
+this by typing ``key 1`` (it's the first one in the listing, the **[E]**
+subkey)::
+
+ gpg> key 1
+
+In the output, you should now see ``ssb*`` on the **[E]** key. The ``*``
+indicates which key is currently "selected." It works as a *toggle*,
+meaning that if you type ``key 1`` again, the ``*`` will disappear and
+the key will not be selected any more.
+
+Now, let's move that key onto the smartcard::
+
+ gpg> keytocard
+ Please select where to store the key:
+ (2) Encryption key
+ Your selection? 2
+
+Since it's our **[E]** key, it makes sense to put it into the Encryption
+slot. When you submit your selection, you will be prompted first for
+your PGP key passphrase, and then for the admin PIN. If the command
+returns without an error, your key has been moved.
+
+**Important**: Now type ``key 1`` again to unselect the first key, and
+``key 2`` to select the **[S]** key::
+
+ gpg> key 1
+ gpg> key 2
+ gpg> keytocard
+ Please select where to store the key:
+ (1) Signature key
+ (3) Authentication key
+ Your selection? 1
+
+You can use the **[S]** key both for Signature and Authentication, but
+we want to make sure it's in the Signature slot, so choose (1). Once
+again, if your command returns without an error, then the operation was
+successful::
+
+ gpg> q
+ Save changes? (y/N) y
+
+Saving the changes will delete the keys you moved to the card from your
+home directory (but it's okay, because we have them in our backups
+should we need to do this again for a replacement smartcard).
+
+Verifying that the keys were moved
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+If you perform ``--list-secret-keys`` now, you will see a subtle
+difference in the output::
+
+ $ gpg --list-secret-keys
+ sec# rsa2048 2018-01-24 [SC] [expires: 2020-01-24]
+ 000000000000000000000000AAAABBBBCCCCDDDD
+ uid [ultimate] Alice Dev <adev@kernel.org>
+ ssb> rsa2048 2018-01-24 [E] [expires: 2020-01-24]
+ ssb> ed25519 2018-01-24 [S]
+
+The ``>`` in the ``ssb>`` output indicates that the subkey is only
+available on the smartcard. If you go back into your secret keys
+directory and look at the contents there, you will notice that the
+``.key`` files there have been replaced with stubs::
+
+ $ cd ~/.gnupg/private-keys-v1.d
+ $ strings *.key | grep 'private-key'
+
+The output should contain ``shadowed-private-key`` to indicate that
+these files are only stubs and the actual content is on the smartcard.
+
+Verifying that the smartcard is functioning
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+To verify that the smartcard is working as intended, you can create a
+signature::
+
+ $ echo "Hello world" | gpg --clearsign > /tmp/test.asc
+ $ gpg --verify /tmp/test.asc
+
+This should ask for your smartcard PIN on your first command, and then
+show "Good signature" after you run ``gpg --verify``.
+
+Congratulations, you have successfully made it extremely difficult to
+steal your digital developer identity!
+
+Other common GnuPG operations
+-----------------------------
+
+Here is a quick reference for some common operations you'll need to do
+with your PGP key.
+
+Mounting your master key offline storage
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+You will need your master key for any of the operations below, so you
+will first need to mount your backup offline storage and tell GnuPG to
+use it::
+
+ $ export GNUPGHOME=/media/disk/foo/gnupg-backup
+ $ gpg --list-secret-keys
+
+You want to make sure that you see ``sec`` and not ``sec#`` in the
+output (the ``#`` means the key is not available and you're still using
+your regular home directory location).
+
+Extending key expiration date
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+The master key has the default expiration date of 2 years from the date
+of creation. This is done both for security reasons and to make obsolete
+keys eventually disappear from keyservers.
+
+To extend the expiration on your key by a year from current date, just
+run::
+
+ $ gpg --quick-set-expire [fpr] 1y
+
+You can also use a specific date if that is easier to remember (e.g.
+your birthday, January 1st, or Canada Day)::
+
+ $ gpg --quick-set-expire [fpr] 2020-07-01
+
+Remember to send the updated key back to keyservers::
+
+ $ gpg --send-key [fpr]
+
+Updating your work directory after any changes
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+After you make any changes to your key using the offline storage, you will
+want to import these changes back into your regular working directory::
+
+ $ gpg --export | gpg --homedir ~/.gnupg --import
+ $ unset GNUPGHOME
+
+
+Using PGP with Git
+==================
+
+One of the core features of Git is its decentralized nature -- once a
+repository is cloned to your system, you have full history of the
+project, including all of its tags, commits and branches. However, with
+hundreds of cloned repositories floating around, how does anyone verify
+that their copy of linux.git has not been tampered with by a malicious
+third party?
+
+Or what happens if a backdoor is discovered in the code and the "Author"
+line in the commit says it was done by you, while you're pretty sure you
+had `nothing to do with it`_?
+
+To address both of these issues, Git introduced PGP integration. Signed
+tags prove the repository integrity by assuring that its contents are
+exactly the same as on the workstation of the developer who created the
+tag, while signed commits make it nearly impossible for someone to
+impersonate you without having access to your PGP keys.
+
+.. _`nothing to do with it`: https://github.com/jayphelps/git-blame-someone-else
+
+Configure git to use your PGP key
+---------------------------------
+
+If you only have one secret key in your keyring, then you don't really
+need to do anything extra, as it becomes your default key. However, if
+you happen to have multiple secret keys, you can tell git which key
+should be used (``[fpr]`` is the fingerprint of your key)::
+
+ $ git config --global user.signingKey [fpr]
+
+**IMPORTANT**: If you have a distinct ``gpg2`` command, then you should
+tell git to always use it instead of the legacy ``gpg`` from version 1::
+
+ $ git config --global gpg.program gpg2
+
+How to work with signed tags
+----------------------------
+
+To create a signed tag, simply pass the ``-s`` switch to the tag
+command::
+
+ $ git tag -s [tagname]
+
+Our recommendation is to always sign git tags, as this allows other
+developers to ensure that the git repository they are pulling from has
+not been maliciously altered.
+
+How to verify signed tags
+~~~~~~~~~~~~~~~~~~~~~~~~~
+
+To verify a signed tag, simply use the ``verify-tag`` command::
+
+ $ git verify-tag [tagname]
+
+If you are pulling a tag from another fork of the project repository,
+git should automatically verify the signature at the tip you're pulling
+and show you the results during the merge operation::
+
+ $ git pull [url] tags/sometag
+
+The merge message will contain something like this::
+
+ Merge tag 'sometag' of [url]
+
+ [Tag message]
+
+ # gpg: Signature made [...]
+ # gpg: Good signature from [...]
+
+If you are verifying someone else's git tag, then you will need to
+import their PGP key. Please refer to the
+":ref:`verify_identities`" section below.
+
+Configure git to always sign annotated tags
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+Chances are, if you're creating an annotated tag, you'll want to sign
+it. To force git to always sign annotated tags, you can set a global
+configuration option::
+
+ $ git config --global tag.forceSignAnnotated true
+
+How to work with signed commits
+-------------------------------
+
+It is easy to create signed commits, but it is much more difficult to
+use them in Linux kernel development, since it relies on patches sent to
+the mailing list, and this workflow does not preserve PGP commit
+signatures. Furthermore, when rebasing your repository to match
+upstream, even your own PGP commit signatures will end up discarded. For
+this reason, most kernel developers don't bother signing their commits
+and will ignore signed commits in any external repositories that they
+rely upon in their work.
+
+However, if you have your working git tree publicly available at some
+git hosting service (kernel.org, infradead.org, ozlabs.org, or others),
+then the recommendation is that you sign all your git commits even if
+upstream developers do not directly benefit from this practice.
+
+We recommend this for the following reasons:
+
+1. Should there ever be a need to perform code forensics or track code
+ provenance, even externally maintained trees carrying PGP commit
+ signatures will be valuable for such purposes.
+2. If you ever need to re-clone your local repository (for example,
+ after a disk failure), this lets you easily verify the repository
+ integrity before resuming your work.
+3. If someone needs to cherry-pick your commits, this allows them to
+ quickly verify their integrity before applying them.
+
+Creating signed commits
+~~~~~~~~~~~~~~~~~~~~~~~
+
+To create a signed commit, you just need to pass the ``-S`` flag to the
+``git commit`` command (it's capital ``-S`` due to collision with
+another flag)::
+
+ $ git commit -S
+
+Configure git to always sign commits
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+You can tell git to always sign commits::
+
+ git config --global commit.gpgSign true
+
+.. note::
+
+ Make sure you configure ``gpg-agent`` before you turn this on.
+
+.. _verify_identities:
+
+How to verify kernel developer identities
+=========================================
+
+Signing tags and commits is easy, but how does one go about verifying
+that the key used to sign something belongs to the actual kernel
+developer and not to a malicious imposter?
+
+Configure auto-key-retrieval using WKD and DANE
+-----------------------------------------------
+
+If you are not already someone with an extensive collection of other
+developers' public keys, then you can jumpstart your keyring by relying
+on key auto-discovery and auto-retrieval. GnuPG can piggyback on other
+delegated trust technologies, namely DNSSEC and TLS, to get you going if
+the prospect of starting your own Web of Trust from scratch is too
+daunting.
+
+Add the following to your ``~/.gnupg/gpg.conf``::
+
+ auto-key-locate wkd,dane,local
+ auto-key-retrieve
+
+DNS-Based Authentication of Named Entities ("DANE") is a method for
+publishing public keys in DNS and securing them using DNSSEC signed
+zones. Web Key Directory ("WKD") is the alternative method that uses
+https lookups for the same purpose. When using either DANE or WKD for
+looking up public keys, GnuPG will validate DNSSEC or TLS certificates,
+respectively, before adding auto-retrieved public keys to your local
+keyring.
+
+Kernel.org publishes the WKD for all developers who have kernel.org
+accounts. Once you have the above changes in your ``gpg.conf``, you can
+auto-retrieve the keys for Linus Torvalds and Greg Kroah-Hartman (if you
+don't already have them)::
+
+ $ gpg --locate-keys torvalds@kernel.org gregkh@kernel.org
+
+If you have a kernel.org account, then you should `add the kernel.org
+UID to your key`_ to make WKD more useful to other kernel developers.
+
+.. _`add the kernel.org UID to your key`: https://korg.wiki.kernel.org/userdoc/mail#adding_a_kernelorg_uid_to_your_pgp_key
+
+Web of Trust (WOT) vs. Trust on First Use (TOFU)
+------------------------------------------------
+
+PGP incorporates a trust delegation mechanism known as the "Web of
+Trust." At its core, this is an attempt to replace the need for
+centralized Certification Authorities of the HTTPS/TLS world. Instead of
+various software makers dictating who should be your trusted certifying
+entity, PGP leaves this responsibility to each user.
+
+Unfortunately, very few people understand how the Web of Trust works.
+While it remains an important aspect of the OpenPGP specification,
+recent versions of GnuPG (2.2 and above) have implemented an alternative
+mechanism called "Trust on First Use" (TOFU). You can think of TOFU as
+"the SSH-like approach to trust." With SSH, the first time you connect
+to a remote system, its key fingerprint is recorded and remembered. If
+the key changes in the future, the SSH client will alert you and refuse
+to connect, forcing you to make a decision on whether you choose to
+trust the changed key or not. Similarly, the first time you import
+someone's PGP key, it is assumed to be valid. If at any point in the
+future GnuPG comes across another key with the same identity, both the
+previously imported key and the new key will be marked as invalid and
+you will need to manually figure out which one to keep.
+
+We recommend that you use the combined TOFU+PGP trust model (which is
+the new default in GnuPG v2). To set it, add (or modify) the
+``trust-model`` setting in ``~/.gnupg/gpg.conf``::
+
+ trust-model tofu+pgp
+
+How to use keyservers (more) safely
+-----------------------------------
+
+If you get a "No public key" error when trying to validate someone's
+tag, then you should attempt to lookup that key using a keyserver. It is
+important to keep in mind that there is absolutely no guarantee that the
+key you retrieve from PGP keyservers belongs to the actual person --
+that much is by design. You are supposed to use the Web of Trust to
+establish key validity.
+
+How to properly maintain the Web of Trust is beyond the scope of this
+document, simply because doing it properly requires both effort and
+dedication that tends to be beyond the caring threshold of most human
+beings. Here are some shortcuts that will help you reduce the risk of
+importing a malicious key.
+
+First, let's say you've tried to run ``git verify-tag`` but it returned
+an error saying the key is not found::
+
+ $ git verify-tag sunxi-fixes-for-4.15-2
+ gpg: Signature made Sun 07 Jan 2018 10:51:55 PM EST
+ gpg: using RSA key DA73759BF8619E484E5A3B47389A54219C0F2430
+ gpg: issuer "wens@...org"
+ gpg: Can't check signature: No public key
+
+Let's query the keyserver for more info about that key fingerprint (the
+fingerprint probably belongs to a subkey, so we can't use it directly
+without finding out the ID of the master key it is associated with)::
+
+ $ gpg --search DA73759BF8619E484E5A3B47389A54219C0F2430
+ gpg: data source: hkp://keys.gnupg.net
+ (1) Chen-Yu Tsai <wens@...org>
+ 4096 bit RSA key C94035C21B4F2AEB, created: 2017-03-14, expires: 2019-03-15
+ Keys 1-1 of 1 for "DA73759BF8619E484E5A3B47389A54219C0F2430". Enter number(s), N)ext, or Q)uit > q
+
+Locate the ID of the master key in the output, in our example
+``C94035C21B4F2AEB``. Now display the key of Linus Torvalds that you
+have on your keyring::
+
+ $ gpg --list-key torvalds@kernel.org
+ pub rsa2048 2011-09-20 [SC]
+ ABAF11C65A2970B130ABE3C479BE3E4300411886
+ uid [ unknown] Linus Torvalds <torvalds@kernel.org>
+ sub rsa2048 2011-09-20 [E]
+
+Next, open the `PGP pathfinder`_. In the "From" field, paste the key
+fingerprint of Linus Torvalds from the output above. In the "To" field,
+paste they key-id you found via ``gpg --search`` of the unknown key, and
+check the results:
+
+- `Finding paths to Linus`_
+
+If you get a few decent trust paths, then it's a pretty good indication
+that it is a valid key. You can add it to your keyring from the
+keyserver now::
+
+ $ gpg --recv-key C94035C21B4F2AEB
+
+This process is not perfect, and you are obviously trusting the
+administrators of the PGP Pathfinder service to not be malicious (in
+fact, this goes against :ref:`devs_not_infra`). However, if you
+do not carefully maintain your own web of trust, then it is a marked
+improvement over blindly trusting keyservers.

+======================================
+Secure Encrypted Virtualization (SEV)
+======================================
+
+Overview
+========
+
+Secure Encrypted Virtualization (SEV) is a feature found on AMD processors.
+
+SEV is an extension to the AMD-V architecture which supports running
+virtual machines (VMs) under the control of a hypervisor. When enabled,
+the memory contents of a VM will be transparently encrypted with a key
+unique to that VM.
+
+The hypervisor can determine the SEV support through the CPUID
+instruction. The CPUID function 0x8000001f reports information related
+to SEV::
+
+ 0x8000001f[eax]:
+ Bit[1] indicates support for SEV
+ ...
+ [ecx]:
+ Bits[31:0] Number of encrypted guests supported simultaneously
+
+If support for SEV is present, MSR 0xc001_0010 (MSR_K8_SYSCFG) and MSR 0xc001_0015
+(MSR_K7_HWCR) can be used to determine if it can be enabled::
+
+ 0xc001_0010:
+ Bit[23] 1 = memory encryption can be enabled
+ 0 = memory encryption can not be enabled
+
+ 0xc001_0015:
+ Bit[0] 1 = memory encryption can be enabled
+ 0 = memory encryption can not be enabled
+
+When SEV support is available, it can be enabled in a specific VM by
+setting the SEV bit before executing VMRUN.::
+
+ VMCB[0x90]:
+ Bit[1] 1 = SEV is enabled
+ 0 = SEV is disabled
+
+SEV hardware uses ASIDs to associate a memory encryption key with a VM.
+Hence, the ASID for the SEV-enabled guests must be from 1 to a maximum value
+defined in the CPUID 0x8000001f[ecx] field.
+
+SEV Key Management
+==================
+
+The SEV guest key management is handled by a separate processor called the AMD
+Secure Processor (AMD-SP). Firmware running inside the AMD-SP provides a secure
+key management interface to perform common hypervisor activities such as
+encrypting bootstrap code, snapshot, migrating and debugging the guest. For more
+information, see the SEV Key Management spec [api-spec]_
+
+KVM implements the following commands to support common lifecycle events of SEV
+guests, such as launching, running, snapshotting, migrating and decommissioning.
+
+1. KVM_SEV_INIT
+---------------
+
+The KVM_SEV_INIT command is used by the hypervisor to initialize the SEV platform
+context. In a typical workflow, this command should be the first command issued.
+
+Returns: 0 on success, -negative on error
+
+2. KVM_SEV_LAUNCH_START
+-----------------------
+
+The KVM_SEV_LAUNCH_START command is used for creating the memory encryption
+context. To create the encryption context, user must provide a guest policy,
+the owner's public Diffie-Hellman (PDH) key and session information.
+
+Parameters: struct kvm_sev_launch_start (in/out)
+
+Returns: 0 on success, -negative on error
+
+::
+
+ struct kvm_sev_launch_start {
+ __u32 handle; /* if zero then firmware creates a new handle */
+ __u32 policy; /* guest's policy */
+
+ __u64 dh_uaddr; /* userspace address pointing to the guest owner's PDH key */
+ __u32 dh_len;
+
+ __u64 session_addr; /* userspace address which points to the guest session information */
+ __u32 session_len;
+ };
+
+On success, the 'handle' field contains a new handle and on error, a negative value.
+
+For more details, see SEV spec Section 6.2.
+
+3. KVM_SEV_LAUNCH_UPDATE_DATA
+-----------------------------
+
+The KVM_SEV_LAUNCH_UPDATE_DATA is used for encrypting a memory region. It also
+calculates a measurement of the memory contents. The measurement is a signature
+of the memory contents that can be sent to the guest owner as an attestation
+that the memory was encrypted correctly by the firmware.
+
+Parameters (in): struct kvm_sev_launch_update_data
+
+Returns: 0 on success, -negative on error
+
+::
+
+ struct kvm_sev_launch_update {
+ __u64 uaddr; /* userspace address to be encrypted (must be 16-byte aligned) */
+ __u32 len; /* length of the data to be encrypted (must be 16-byte aligned) */
+ };
+
+For more details, see SEV spec Section 6.3.
+
+4. KVM_SEV_LAUNCH_MEASURE
+-------------------------
+
+The KVM_SEV_LAUNCH_MEASURE command is used to retrieve the measurement of the
+data encrypted by the KVM_SEV_LAUNCH_UPDATE_DATA command. The guest owner may
+wait to provide the guest with confidential information until it can verify the
+measurement. Since the guest owner knows the initial contents of the guest at
+boot, the measurement can be verified by comparing it to what the guest owner
+expects.
+
+Parameters (in): struct kvm_sev_launch_measure
+
+Returns: 0 on success, -negative on error
+
+::
+
+ struct kvm_sev_launch_measure {
+ __u64 uaddr; /* where to copy the measurement */
+ __u32 len; /* length of measurement blob */
+ };
+
+For more details on the measurement verification flow, see SEV spec Section 6.4.
+
+5. KVM_SEV_LAUNCH_FINISH
+------------------------
+
+After completion of the launch flow, the KVM_SEV_LAUNCH_FINISH command can be
+issued to make the guest ready for the execution.
+
+Returns: 0 on success, -negative on error
+
+6. KVM_SEV_GUEST_STATUS
+-----------------------
+
+The KVM_SEV_GUEST_STATUS command is used to retrieve status information about a
+SEV-enabled guest.
+
+Parameters (out): struct kvm_sev_guest_status
+
+Returns: 0 on success, -negative on error
+
+::
+
+ struct kvm_sev_guest_status {
+ __u32 handle; /* guest handle */
+ __u32 policy; /* guest policy */
+ __u8 state; /* guest state (see enum below) */
+ };
+
+SEV guest state:
+
+::
+
+ enum {
+ SEV_STATE_INVALID = 0;
+ SEV_STATE_LAUNCHING, /* guest is currently being launched */
+ SEV_STATE_SECRET, /* guest is being launched and ready to accept the ciphertext data */
+ SEV_STATE_RUNNING, /* guest is fully launched and running */
+ SEV_STATE_RECEIVING, /* guest is being migrated in from another SEV machine */
+ SEV_STATE_SENDING /* guest is getting migrated out to another SEV machine */
+ };
+
+7. KVM_SEV_DBG_DECRYPT
+----------------------
+
+The KVM_SEV_DEBUG_DECRYPT command can be used by the hypervisor to request the
+firmware to decrypt the data at the given memory region.
+
+Parameters (in): struct kvm_sev_dbg
+
+Returns: 0 on success, -negative on error
+
+::
+
+ struct kvm_sev_dbg {
+ __u64 src_uaddr; /* userspace address of data to decrypt */
+ __u64 dst_uaddr; /* userspace address of destination */
+ __u32 len; /* length of memory region to decrypt */
+ };
+
+The command returns an error if the guest policy does not allow debugging.
+
+8. KVM_SEV_DBG_ENCRYPT
+----------------------
+
+The KVM_SEV_DEBUG_ENCRYPT command can be used by the hypervisor to request the
+firmware to encrypt the data at the given memory region.
+
+Parameters (in): struct kvm_sev_dbg
+
+Returns: 0 on success, -negative on error
+
+::
+
+ struct kvm_sev_dbg {
+ __u64 src_uaddr; /* userspace address of data to encrypt */
+ __u64 dst_uaddr; /* userspace address of destination */
+ __u32 len; /* length of memory region to encrypt */
+ };
+
+The command returns an error if the guest policy does not allow debugging.
+
+9. KVM_SEV_LAUNCH_SECRET
+------------------------
+
+The KVM_SEV_LAUNCH_SECRET command can be used by the hypervisor to inject secret
+data after the measurement has been validated by the guest owner.
+
+Parameters (in): struct kvm_sev_launch_secret
+
+Returns: 0 on success, -negative on error
+
+::
+
+ struct kvm_sev_launch_secret {
+ __u64 hdr_uaddr; /* userspace address containing the packet header */
+ __u32 hdr_len;
+
+ __u64 guest_uaddr; /* the guest memory region where the secret should be injected */
+ __u32 guest_len;
+
+ __u64 trans_uaddr; /* the hypervisor memory region which contains the secret */
+ __u32 trans_len;
+ };

+It is used in the SEV-enabled guest. When encryption is enabled, a guest

-KVM/ARM VGIC Forwarded Physical Interrupts
-==========================================
-
-The KVM/ARM code implements software support for the ARM Generic
-Interrupt Controller's (GIC's) hardware support for virtualization by
-allowing software to inject virtual interrupts to a VM, which the guest
-OS sees as regular interrupts. The code is famously known as the VGIC.
-
-Some of these virtual interrupts, however, correspond to physical
-interrupts from real physical devices. One example could be the
-architected timer, which itself supports virtualization, and therefore
-lets a guest OS program the hardware device directly to raise an
-interrupt at some point in time. When such an interrupt is raised, the
-host OS initially handles the interrupt and must somehow signal this
-event as a virtual interrupt to the guest. Another example could be a
-passthrough device, where the physical interrupts are initially handled
-by the host, but the device driver for the device lives in the guest OS
-and KVM must therefore somehow inject a virtual interrupt on behalf of
-the physical one to the guest OS.
-
-These virtual interrupts corresponding to a physical interrupt on the
-host are called forwarded physical interrupts, but are also sometimes
-referred to as 'virtualized physical interrupts' and 'mapped interrupts'.
-
-Forwarded physical interrupts are handled slightly differently compared
-to virtual interrupts generated purely by a software emulated device.
-
-
-The HW bit
-----------
-Virtual interrupts are signalled to the guest by programming the List
-Registers (LRs) on the GIC before running a VCPU. The LR is programmed
-with the virtual IRQ number and the state of the interrupt (Pending,
-Active, or Pending+Active). When the guest ACKs and EOIs a virtual
-interrupt, the LR state moves from Pending to Active, and finally to
-inactive.
-
-The LRs include an extra bit, called the HW bit. When this bit is set,
-KVM must also program an additional field in the LR, the physical IRQ
-number, to link the virtual with the physical IRQ.
-
-When the HW bit is set, KVM must EITHER set the Pending OR the Active
-bit, never both at the same time.
-
-Setting the HW bit causes the hardware to deactivate the physical
-interrupt on the physical distributor when the guest deactivates the
-corresponding virtual interrupt.
-
-
-Forwarded Physical Interrupts Life Cycle
-----------------------------------------
-
-The state of forwarded physical interrupts is managed in the following way:
-
- - The physical interrupt is acked by the host, and becomes active on
- the physical distributor (*).
- - KVM sets the LR.Pending bit, because this is the only way the GICV
- interface is going to present it to the guest.
- - LR.Pending will stay set as long as the guest has not acked the interrupt.
- - LR.Pending transitions to LR.Active on the guest read of the IAR, as
- expected.
- - On guest EOI, the *physical distributor* active bit gets cleared,
- but the LR.Active is left untouched (set).
- - KVM clears the LR on VM exits when the physical distributor
- active state has been cleared.
-
-(*): The host handling is slightly more complicated. For some forwarded
-interrupts (shared), KVM directly sets the active state on the physical
-distributor before entering the guest, because the interrupt is never actually
-handled on the host (see details on the timer as an example below). For other
-forwarded interrupts (non-shared) the host does not deactivate the interrupt
-when the host ISR completes, but leaves the interrupt active until the guest
-deactivates it. Leaving the interrupt active is allowed, because Linux
-configures the physical GIC with EOIMode=1, which causes EOI operations to
-perform a priority drop allowing the GIC to receive other interrupts of the
-default priority.
-
-
-Forwarded Edge and Level Triggered PPIs and SPIs
-------------------------------------------------
-Forwarded physical interrupts injected should always be active on the
-physical distributor when injected to a guest.
-
-Level-triggered interrupts will keep the interrupt line to the GIC
-asserted, typically until the guest programs the device to deassert the
-line. This means that the interrupt will remain pending on the physical
-distributor until the guest has reprogrammed the device. Since we
-always run the VM with interrupts enabled on the CPU, a pending
-interrupt will exit the guest as soon as we switch into the guest,
-preventing the guest from ever making progress as the process repeats
-over and over. Therefore, the active state on the physical distributor
-must be set when entering the guest, preventing the GIC from forwarding
-the pending interrupt to the CPU. As soon as the guest deactivates the
-interrupt, the physical line is sampled by the hardware again and the host
-takes a new interrupt if and only if the physical line is still asserted.
-
-Edge-triggered interrupts do not exhibit the same problem with
-preventing guest execution that level-triggered interrupts do. One
-option is to not use HW bit at all, and inject edge-triggered interrupts
-from a physical device as pure virtual interrupts. But that would
-potentially slow down handling of the interrupt in the guest, because a
-physical interrupt occurring in the middle of the guest ISR would
-preempt the guest for the host to handle the interrupt. Additionally,
-if you configure the system to handle interrupts on a separate physical
-core from that running your VCPU, you still have to interrupt the VCPU
-to queue the pending state onto the LR, even though the guest won't use
-this information until the guest ISR completes. Therefore, the HW
-bit should always be set for forwarded edge-triggered interrupts. With
-the HW bit set, the virtual interrupt is injected and additional
-physical interrupts occurring before the guest deactivates the interrupt
-simply mark the state on the physical distributor as Pending+Active. As
-soon as the guest deactivates the interrupt, the host takes another
-interrupt if and only if there was a physical interrupt between injecting
-the forwarded interrupt to the guest and the guest deactivating the
-interrupt.
-
-Consequently, whenever we schedule a VCPU with one or more LRs with the
-HW bit set, the interrupt must also be active on the physical
-distributor.
-
-
-Forwarded LPIs
---------------
-LPIs, introduced in GICv3, are always edge-triggered and do not have an
-active state. They become pending when a device signal them, and as
-soon as they are acked by the CPU, they are inactive again.
-
-It therefore doesn't make sense, and is not supported, to set the HW bit
-for physical LPIs that are forwarded to a VM as virtual interrupts,
-typically virtual SPIs.
-
-For LPIs, there is no other choice than to preempt the VCPU thread if
-necessary, and queue the pending state onto the LR.
-
-
-Putting It Together: The Architected Timer
-------------------------------------------
-The architected timer is a device that signals interrupts with level
-triggered semantics. The timer hardware is directly accessed by VCPUs
-which program the timer to fire at some point in time. Each VCPU on a
-system programs the timer to fire at different times, and therefore the
-hardware is multiplexed between multiple VCPUs. This is implemented by
-context-switching the timer state along with each VCPU thread.
-
-However, this means that a scenario like the following is entirely
-possible, and in fact, typical:
-
-1. KVM runs the VCPU
-2. The guest programs the time to fire in T+100
-3. The guest is idle and calls WFI (wait-for-interrupts)
-4. The hardware traps to the host
-5. KVM stores the timer state to memory and disables the hardware timer
-6. KVM schedules a soft timer to fire in T+(100 - time since step 2)
-7. KVM puts the VCPU thread to sleep (on a waitqueue)
-8. The soft timer fires, waking up the VCPU thread
-9. KVM reprograms the timer hardware with the VCPU's values
-10. KVM marks the timer interrupt as active on the physical distributor
-11. KVM injects a forwarded physical interrupt to the guest
-12. KVM runs the VCPU
-
-Notice that KVM injects a forwarded physical interrupt in step 11 without
-the corresponding interrupt having actually fired on the host. That is
-exactly why we mark the timer interrupt as active in step 10, because
-the active state on the physical distributor is part of the state
-belonging to the timer hardware, which is context-switched along with
-the VCPU thread.
-
-If the guest does not idle because it is busy, the flow looks like this
-instead:
-
-1. KVM runs the VCPU
-2. The guest programs the time to fire in T+100
-4. At T+100 the timer fires and a physical IRQ causes the VM to exit
- (note that this initially only traps to EL2 and does not run the host ISR
- until KVM has returned to the host).
-5. With interrupts still disabled on the CPU coming back from the guest, KVM
- stores the virtual timer state to memory and disables the virtual hw timer.
-6. KVM looks at the timer state (in memory) and injects a forwarded physical
- interrupt because it concludes the timer has expired.
-7. KVM marks the timer interrupt as active on the physical distributor
-7. KVM enables the timer, enables interrupts, and runs the VCPU
-
-Notice that again the forwarded physical interrupt is injected to the
-guest without having actually been handled on the host. In this case it
-is because the physical interrupt is never actually seen by the host because the
-timer is disabled upon guest return, and the virtual forwarded interrupt is
-injected on the KVM guest entry path.

* Mapping the whole extended configuration space would require 256 MiB of

link_notify callback when the pipeline is modified. It should be
decided whether this feature is useful enough to make it generally
available by exporting to v4l2-core.
+
+- The OF graph is walked at probe time to form the list of fwnodes to
+ be passed to v4l2_async_notifier_register(), starting from the IPU
+ CSI ports. And after all async subdevices have been bound,
+ v4l2_fwnode_parse_link() is used to form the media links between
+ the entities discovered by walking the OF graph.
+
+ While this approach allows support for arbitrary OF graphs, there
+ are some assumptions for this to work:
+
+ 1. All port parent nodes reachable in the graph from the IPU CSI
+ ports bind to V4L2 async subdevice drivers.
+
+ If a device has mixed-use ports such as video plus audio, the
+ endpoints from the audio ports are followed to devices that must
+ bind to V4L2 subdevice drivers, and not for example, to an ALSA
+ driver or a non-V4L2 media driver. If the device were bound to
+ such a driver, imx-media would never get an async completion
+ notification because the device fwnode was added to the async
+ list, but the driver does not interface with the V4L2 async
+ framework.
+
+ 2. Every port reachable in the graph is treated as a media pad,
+ owned by the V4L2 subdevice that is bound to the port's parent.
+
+ This presents problems for devices that don't make this port = pad
+ assumption. Examples are SMIAPP compatible cameras which define only
+ a single output port node, but which define multiple pads owned
+ by multiple subdevices (pixel-array, binner, scaler). Or video
+ decoders (entity function MEDIA_ENT_F_ATV_DECODER), which also define
+ only a single output port node, but define multiple pads for video,
+ VBI, and audio out.
+
+ A workaround at present is to set the port reg properties to
+ correspond to the media pad index that the port represents. A
+ possible long-term solution is to implement a subdev API that
+ maps a port id to a media pad index.
+
+ 3. Every endpoint of a port reachable in the graph is treated as
+ a media link, between V4L2 subdevices that are bound to the
+ port parents of the local and remote endpoints.
+
+ Which means a port must not contain mixed-use endpoints, they
+ must all refer to media links between V4L2 subdevices.

-1. Both ir-kbd-i2c and lirc_zilog provide support for RX events for
-the chips supported by lirc_zilog. Before moving lirc_zilog out of staging:
-
-a. ir-kbd-i2c needs a module parameter added to allow the user to tell
- ir-kbd-i2c to ignore Z8 IR units.
-
-b. lirc_zilog should provide Rx key presses to the rc core like ir-kbd-i2c
- does.
-
-
-2. lirc_zilog module ref-counting need examination. It has not been
-verified that cdev and lirc_dev will take the proper module references on
-lirc_zilog to prevent removal of lirc_zilog when the /dev/lircN device node
-is open.
-
-(The good news is ref-counting of lirc_zilog internal structures appears to be
-complete. Testing has shown the cx18 module can be unloaded out from under
-irw + lircd + lirc_dev, with the /dev/lirc0 device node open, with no adverse
-effects. The cx18 module could then be reloaded and irw properly began
-receiving button presses again and ir_send worked without error.)
-
-
-3. Bridge drivers, if able, should provide a chip reset() callback
-to lirc_zilog via struct IR_i2c_init_data. cx18 and ivtv already have routines
-to perform Z8 chip resets via GPIO manipulations. This would allow lirc_zilog
-to bring the chip back to normal when it hangs, in the same places the
-original lirc_pvr150 driver code does. This is not strictly needed, so it
-is not required to move lirc_zilog out of staging.
-
-Note: Both lirc_zilog and ir-kbd-i2c support the Zilog Z8 for IR, as programmed
-and installed on Hauppauge products. When working on either module, developers
-must consider at least the following bridge drivers which mention an IR Rx unit
-at address 0x71 (indicative of a Z8):
-
- ivtv cx18 hdpvr pvrusb2 bt8xx cx88 saa7134

- * A watchdog timer event will, after reset, block writes to the WDT_CLEAR

- *
- * If you still want to use the WDT after a WDT reset a small code can be
- * insterted at the startup checking the AVR32_PM.rcause register for WDT reset
- * and use a GPIO pin to reset the system. This method requires that one of the
- * GPIO pins are available and connected externally to the RESET_N pin. After
- * the GPIO pin has pulled down the reset line the GPIO will be reset and leave
- * the pin tristated with pullup.

- * Overview:
- *
- * Events are subscribed per-filehandle. An event specification consists of a
- * type and is optionally associated with an object identified through the
- * 'id' field. So an event is uniquely identified by the (type, id) tuple.
- *
- * The v4l2-fh struct has a list of subscribed events. The v4l2_subscribed_event
- * struct is added to that list, one for every subscribed event.
- *
- * Each v4l2_subscribed_event struct ends with an array of v4l2_kevent structs.
- * This array (ringbuffer, really) is used to store any events raised by the
- * driver. The v4l2_kevent struct links into the 'available' list of the
- * v4l2_fh struct so VIDIOC_DQEVENT will know which event to dequeue first.
- *
- * Finally, if the event subscription is associated with a particular object
- * such as a V4L2 control, then that object needs to know about that as well
- * so that an event can be raised by that object. So the 'node' field can
- * be used to link the v4l2_subscribed_event struct into a list of that
- * object.
- *
- * So to summarize:
- *
- * struct v4l2_fh has two lists: one of the subscribed events, and one of the
- * pending events.
- *
- * struct v4l2_subscribed_event has a ringbuffer of raised (pending) events of
- * that particular type.
- *
- * If struct v4l2_subscribed_event is associated with a specific object, then
- * that object will have an internal list of struct v4l2_subscribed_event so
- * it knows who subscribed an event to that object.
