====================
Netfilter fixes for net
The following patchset contains three Netfilter fixes for your net tree,
they are:
* Fix missing generation sequence initialization which results in a splat
if lockdep is enabled, it was introduced in the recent works to improve
nf_conntrack scalability, from Andrey Vagin.
* Don't flush the GRE keymap list in nf_conntrack when the pptp helper is
disabled otherwise this crashes due to a double release, from Andrey
Vagin.
* Fix nf_tables cmp fast in big endian, from Patrick McHardy.

- <para>As a remedy the present version of the V4L2 API relaxed the
-concept of device types with specific names and minor numbers. For
-compatibility with old applications drivers must still register different
-minor numbers to assign a default function to the device. But if related
-functions are supported by the driver they must be available under all
-registered minor numbers. The desired function can be selected after

-with <application>dd</application> or <application>cat</application>)
-<filename>/dev/video</filename> captures video images, while
-<filename>/dev/vbi</filename> captures raw VBI data.
-<filename>/dev/radio</filename> (81, 64) is invariable a radio device,
-unrelated to the video functions. Being unrelated does not imply the
-devices can be used at the same time, however. The &func-open;
-function may very well return an &EBUSY;.</para>
+ <para>The V4L2 API was designed with the idea that one device node could support

+makes no provisions to find these related devices. Some really
+complex devices use the Media Controller (see <xref linkend="media_controller" />)

+and while some code exists that uses sysfs to discover related devices
+(see libmedia_dev in the <ulink url="http://git.linuxtv.org/v4l-utils/">v4l-utils</ulink>

<para>Currently, most analog and digital devices have a Infrared input for remote controllers. Each
manufacturer has their own type of control. It is not rare for the same manufacturer to ship different
types of controls, depending on the device.</para>
+<para>A Remote Controller interface is mapped as a normal evdev/input interface, just like a keyboard or a mouse.
+So, it uses all ioctls already defined for any other input devices.</para>
+<para>However, remove controllers are more flexible than a normal input device, as the IR
+receiver (and/or transmitter) can be used in conjunction with a wide variety of different IR remotes.</para>

+ <para>These ioctls can be used to get or set an EDID associated with an input
+ from a receiver or an output of a transmitter device. They can be
+ used with subdevice nodes (/dev/v4l-subdevX) or with video nodes (/dev/videoX).</para>
+
+ <para>When used with video nodes the <structfield>pad</structfield> field represents the
+ input (for video capture devices) or output (for video output devices) index as
+ is returned by &VIDIOC-ENUMINPUT; and &VIDIOC-ENUMOUTPUT; respectively. When used
+ with subdevice nodes the <structfield>pad</structfield> field represents the
+ input or output pad of the subdevice. If there is no EDID support for the given
+ <structfield>pad</structfield> value, then the &EINVAL; will be returned.</para>
+
+ <para>To get the EDID data the application has to fill in the <structfield>pad</structfield>,
+ <structfield>start_block</structfield>, <structfield>blocks</structfield> and <structfield>edid</structfield>
+ fields and call <constant>VIDIOC_G_EDID</constant>. The current EDID from block
+ <structfield>start_block</structfield> and of size <structfield>blocks</structfield>
+ will be placed in the memory <structfield>edid</structfield> points to. The <structfield>edid</structfield>
+ pointer must point to memory at least <structfield>blocks</structfield> * 128 bytes
+ large (the size of one block is 128 bytes).</para>
+
+ <para>If there are fewer blocks than specified, then the driver will set <structfield>blocks</structfield>
+ to the actual number of blocks. If there are no EDID blocks available at all, then the error code
+ ENODATA is set.</para>
+
+ <para>If blocks have to be retrieved from the sink, then this call will block until they
+ have been read.</para>
+
+ <para>To set the EDID blocks of a receiver the application has to fill in the <structfield>pad</structfield>,
+ <structfield>blocks</structfield> and <structfield>edid</structfield> fields and set
+ <structfield>start_block</structfield> to 0. It is not possible to set part of an EDID,
+ it is always all or nothing. Setting the EDID data is only valid for receivers as it makes
+ no sense for a transmitter.</para>
+
+ <para>The driver assumes that the full EDID is passed in. If there are more EDID blocks than
+ the hardware can handle then the EDID is not written, but instead the error code E2BIG is set
+ and <structfield>blocks</structfield> is set to the maximum that the hardware supports.
+ If <structfield>start_block</structfield> is any
+ value other than 0 then the error code EINVAL is set.</para>
+
+ <para>To disable an EDID you set <structfield>blocks</structfield> to 0. Depending on the
+ hardware this will drive the hotplug pin low and/or block the source from reading the EDID
+ data in some way. In any case, the end result is the same: the EDID is no longer available.

+ Part 7 - Locking
+
+The common clock framework uses two global locks, the prepare lock and the
+enable lock.
+
+The enable lock is a spinlock and is held across calls to the .enable,
+.disable and .is_enabled operations. Those operations are thus not allowed to
+sleep, and calls to the clk_enable(), clk_disable() and clk_is_enabled() API
+functions are allowed in atomic context.
+
+The prepare lock is a mutex and is held across calls to all other operations.
+All those operations are allowed to sleep, and calls to the corresponding API
+functions are not allowed in atomic context.
+
+This effectively divides operations in two groups from a locking perspective.
+
+Drivers don't need to manually protect resources shared between the operations
+of one group, regardless of whether those resources are shared by multiple
+clocks or not. However, access to resources that are shared between operations
+of the two groups needs to be protected by the drivers. An example of such a
+resource would be a register that controls both the clock rate and the clock
+enable/disable state.
+
+The clock framework is reentrant, in that a driver is allowed to call clock
+framework functions from within its implementation of clock operations. This
+can for instance cause a .set_rate operation of one clock being called from
+within the .set_rate operation of another clock. This case must be considered
+in the driver implementations, but the code flow is usually controlled by the
+driver in that case.
+
+Note that locking must also be considered when code outside of the common
+clock framework needs to access resources used by the clock operations. This
+is considered out of scope of this document.

Q: I don't see my action being called for all CPUs already up and running?
A: Yes, CPU notifiers are called only when new CPUs are on-lined or offlined.
If you need to perform some action for each cpu already in the system, then
+ do this:
for_each_online_cpu(i) {
foobar_cpu_callback(&foobar_cpu_notifier, CPU_UP_PREPARE, i);

+Introduction
+============
+
+dm-era is a target that behaves similar to the linear target. In
+addition it keeps track of which blocks were written within a user
+defined period of time called an 'era'. Each era target instance
+maintains the current era as a monotonically increasing 32-bit
+counter.
+
+Use cases include tracking changed blocks for backup software, and
+partially invalidating the contents of a cache to restore cache
+coherency after rolling back a vendor snapshot.
+
+Constructor
+===========
+
+ era <metadata dev> <origin dev> <block size>
+
+ metadata dev : fast device holding the persistent metadata
+ origin dev : device holding data blocks that may change
+ block size : block size of origin data device, granularity that is
+ tracked by the target
+
+Messages
+========
+
+None of the dm messages take any arguments.
+
+checkpoint
+----------
+
+Possibly move to a new era. You shouldn't assume the era has
+incremented. After sending this message, you should check the
+current era via the status line.
+
+take_metadata_snap
+------------------
+
+Create a clone of the metadata, to allow a userland process to read it.
+
+drop_metadata_snap
+------------------
+
+Drop the metadata snapshot.
+
+Status
+======
+
+<metadata block size> <#used metadata blocks>/<#total metadata blocks>
+<current era> <held metadata root | '-'>
+
+metadata block size : Fixed block size for each metadata block in
+ sectors
+#used metadata blocks : Number of metadata blocks used
+#total metadata blocks : Total number of metadata blocks
+current era : The current era
+held metadata root : The location, in blocks, of the metadata root
+ that has been 'held' for userspace read
+ access. '-' indicates there is no held root
+
+Detailed use case
+=================
+
+The scenario of invalidating a cache when rolling back a vendor
+snapshot was the primary use case when developing this target:
+
+Taking a vendor snapshot
+------------------------
+
+- Send a checkpoint message to the era target
+- Make a note of the current era in its status line
+- Take vendor snapshot (the era and snapshot should be forever
+ associated now).
+
+Rolling back to an vendor snapshot
+----------------------------------
+
+- Cache enters passthrough mode (see: dm-cache's docs in cache.txt)
+- Rollback vendor storage
+- Take metadata snapshot
+- Ascertain which blocks have been written since the snapshot was taken
+ by checking each block's era
+- Invalidate those blocks in the caching software
+- Cache returns to writeback/writethrough mode
+
+Memory usage
+============
+
+The target uses a bitset to record writes in the current era. It also
+has a spare bitset ready for switching over to a new era. Other than
+that it uses a few 4k blocks for updating metadata.
+
+ (4 * nr_blocks) bytes + buffers
+
+Resilience
+==========
+
+Metadata is updated on disk before a write to a previously unwritten
+block is performed. As such dm-era should not be effected by a hard
+crash such as power failure.
+
+Userland tools
+==============
+
+Userland tools are found in the increasingly poorly named
+thin-provisioning-tools project:

+clock-indices: If the identifyng number for the clocks in the node
+ is not linear from zero, then the this mapping allows
+ the mapping of identifiers into the clock-output-names
+ array.
+
+For example, if we have two clocks <&oscillator 1> and <&oscillator 3>:
+
+ oscillator {
+ compatible = "myclocktype";
+ #clock-cells = <1>;
+ clock-indices = <1>, <3>;
+ clock-output-names = "clka", "clkb";
+ }
+
+ This ensures we do not have any empty nodes in clock-output-names

+* Freescale enhanced Direct Memory Access(eDMA) Controller
+
+ The eDMA channels have multiplex capability by programmble memory-mapped
+registers. channels are split into two groups, called DMAMUX0 and DMAMUX1,
+specific DMA request source can only be multiplexed by any channel of certain
+group, DMAMUX0 or DMAMUX1, but not both.
+
+* eDMA Controller
+Required properties:
+- compatible :
+ - "fsl,vf610-edma" for eDMA used similar to that on Vybrid vf610 SoC
+- reg : Specifies base physical address(s) and size of the eDMA registers.
+ The 1st region is eDMA control register's address and size.
+ The 2nd and the 3rd regions are programmable channel multiplexing
+ control register's address and size.
+- interrupts : A list of interrupt-specifiers, one for each entry in
+ interrupt-names.
+- interrupt-names : Should contain:
+ "edma-tx" - the transmission interrupt
+ "edma-err" - the error interrupt
+- #dma-cells : Must be <2>.
+ The 1st cell specifies the DMAMUX(0 for DMAMUX0 and 1 for DMAMUX1).
+ Specific request source can only be multiplexed by specific channels
+ group called DMAMUX.
+ The 2nd cell specifies the request source(slot) ID.
+ See the SoC's reference manual for all the supported request sources.
+- dma-channels : Number of channels supported by the controller
+- clock-names : A list of channel group clock names. Should contain:
+ "dmamux0" - clock name of mux0 group
+ "dmamux1" - clock name of mux1 group
+- clocks : A list of phandle and clock-specifier pairs, one for each entry in
+ clock-names.
+
+Optional properties:

+and GPIO flags as accepted by the "qe_pio_e" gpio-controller.
+
+1.1) GPIO specifier best practices
+----------------------------------
+
+A gpio-specifier should contain a flag indicating the GPIO polarity; active-
+high or active-low. If it does, the follow best practices should be followed:
+
+The gpio-specifier's polarity flag should represent the physical level at the
+GPIO controller that achieves (or represents, for inputs) a logically asserted
+value at the device. The exact definition of logically asserted should be
+defined by the binding for the device. If the board inverts the signal between
+the GPIO controller and the device, then the gpio-specifier will represent the
+opposite physical level than the signal at the device's pin.
+
+When the device's signal polarity is configurable, the binding for the
+device must either:
+
+a) Define a single static polarity for the signal, with the expectation that
+any software using that binding would statically program the device to use
+that signal polarity.
+
+The static choice of polarity may be either:
+
+a1) (Preferred) Dictated by a binding-specific DT property.
+
+or:
+
+a2) Defined statically by the DT binding itself.
+
+In particular, the polarity cannot be derived from the gpio-specifier, since
+that would prevent the DT from separately representing the two orthogonal
+concepts of configurable signal polarity in the device, and possible board-
+level signal inversion.
+
+or:
+
+b) Pick a single option for device signal polarity, and document this choice
+in the binding. The gpio-specifier should represent the polarity of the signal
+(at the GPIO controller) assuming that the device is configured for this
+particular signal polarity choice. If software chooses to program the device
+to generate or receive a signal of the opposite polarity, software will be
+responsible for correctly interpreting (inverting) the GPIO signal at the GPIO
+controller.
2) gpio-controller nodes
------------------------
-Every GPIO controller node must both an empty "gpio-controller"
-property, and have #gpio-cells contain the size of the gpio-specifier.
+Every GPIO controller node must contain both an empty "gpio-controller"
+property, and a #gpio-cells integer property, which indicates the number of
+cells in a gpio-specifier.
Example of two SOC GPIO banks defined as gpio-controller nodes:
qe_pio_a: gpio-controller@1400 {
- #gpio-cells = <2>;
compatible = "fsl,qe-pario-bank-a", "fsl,qe-pario-bank";
reg = <0x1400 0x18>;
gpio-controller;
+ #gpio-cells = <2>;
};
qe_pio_e: gpio-controller@1460 {
- #gpio-cells = <2>;
compatible = "fsl,qe-pario-bank-e", "fsl,qe-pario-bank";
reg = <0x1460 0x18>;

+FocalTech EDT-FT5x06 Polytouch driver
+=====================================
+
+There are 3 variants of the chip for various touch panel sizes
+FT5206GE1 2.8" .. 3.8"
+FT5306DE4 4.3" .. 7"
+FT5406EE8 7" .. 8.9"
+
+The software interface is identical for all those chips, so that
+currently there is no need for the driver to distinguish between the
+different chips. Nevertheless distinct compatible strings are used so
+that a distinction can be added if necessary without changing the DT
+bindings.
+
+
+Required properties:
+ - compatible: "edt,edt-ft5206"
+ or: "edt,edt-ft5306"
+ or: "edt,edt-ft5406"
+
+ - reg: I2C slave address of the chip (0x38)
+ - interrupt-parent: a phandle pointing to the interrupt controller
+ serving the interrupt for this chip
+ - interrupts: interrupt specification for the touchdetect
+ interrupt
+
+Optional properties:
+ - reset-gpios: GPIO specification for the RESET input
+ - wake-gpios: GPIO specification for the WAKE input
+
+ - pinctrl-names: should be "default"
+ - pinctrl-0: a phandle pointing to the pin settings for the
+ control gpios
+
+ - threshold: allows setting the "click"-threshold in the range
+ from 20 to 80.
+
+ - gain: allows setting the sensitivity in the range from 0 to
+ 31. Note that lower values indicate higher
+ sensitivity.
+
+ - offset: allows setting the edge compensation in the range from
+ 0 to 31.
+
+Example:
+ polytouch: edt-ft5x06@38 {
+ compatible = "edt,edt-ft5406", "edt,edt-ft5x06";

+Samsung S5C73M3 8Mp camera ISP
+------------------------------
+
+The S5C73M3 camera ISP supports MIPI CSI-2 and parallel (ITU-R BT.656) video
+data busses. The I2C bus is the main control bus and additionally the SPI bus
+is used, mostly for transferring the firmware to and from the device. Two
+slave device nodes corresponding to these control bus interfaces are required
+and should be placed under respective bus controller nodes.
+
+I2C slave device node
+---------------------
+
+Required properties:
+
+- compatible : "samsung,s5c73m3";
+- reg : I2C slave address of the sensor;
+- vdd-int-supply : digital power supply (1.2V);
+- vdda-supply : analog power supply (1.2V);
+- vdd-reg-supply : regulator input power supply (2.8V);
+- vddio-host-supply : host I/O power supply (1.8V to 2.8V);
+- vddio-cis-supply : CIS I/O power supply (1.2V to 1.8V);
+- vdd-af-supply : lens power supply (2.8V);
+- xshutdown-gpios : specifier of GPIO connected to the XSHUTDOWN pin;
+- standby-gpios : specifier of GPIO connected to the STANDBY pin;
+- clocks : should contain list of phandle and clock specifier pairs
+ according to common clock bindings for the clocks described
+ in the clock-names property;
+- clock-names : should contain "cis_extclk" entry for the CIS_EXTCLK clock;
+
+Optional properties:
+
+- clock-frequency : the frequency at which the "cis_extclk" clock should be
+ configured to operate, in Hz; if this property is not
+ specified default 24 MHz value will be used.
+
+The common video interfaces bindings (see video-interfaces.txt) should be used
+to specify link from the S5C73M3 to an external image data receiver. The S5C73M3
+device node should contain one 'port' child node with an 'endpoint' subnode for
+this purpose. The data link from a raw image sensor to the S5C73M3 can be
+similarly specified, but it is optional since the S5C73M3 ISP and a raw image
+sensor are usually inseparable and form a hybrid module.
+
+Following properties are valid for the endpoint node(s):
+
+endpoint subnode
+----------------
+
+- data-lanes : (optional) specifies MIPI CSI-2 data lanes as covered in
+ video-interfaces.txt. This sensor doesn't support data lane remapping
+ and physical lane indexes in subsequent elements of the array should
+ be only consecutive ascending values.

+
+The reset controller(rstc) manages various reset sources. This module provides

+
+For SiRFSoC, RESET_INDEX is just reset_bit defined in SW_RST0 and SW_RST1 registers.

+STMicroelectronics STi family Sysconfig Peripheral Powerdown Reset Controller
+=============================================================================
+
+This binding describes a reset controller device that is used to enable and
+disable on-chip peripheral controllers such as USB and SATA, using
+"powerdown" control bits found in the STi family SoC system configuration
+registers. These have been grouped together into a single reset controller
+device for convenience.
+
+The actual action taken when powerdown is asserted is hardware dependent.
+However, when asserted it may not be possible to access the hardware's
+registers and after an assert/deassert sequence the hardware's previous state
+may no longer be valid.
+
+Please refer to reset.txt in this directory for common reset
+controller binding usage.
+
+Required properties:
+- compatible: Should be "st,<chip>-powerdown"
+ ex: "st,stih415-powerdown", "st,stih416-powerdown"
+- #reset-cells: 1, see below
+
+example:
+
+ powerdown: powerdown-controller {
+ #reset-cells = <1>;
+ compatible = "st,stih415-powerdown";
+ };
+
+
+Specifying powerdown control of devices
+=======================================
+
+Device nodes should specify the reset channel required in their "resets"
+property, containing a phandle to the powerdown device node and an
+index specifying which channel to use, as described in reset.txt
+
+example:
+
+ usb1: usb@fe200000 {
+ resets = <&powerdown STIH41X_USB1_POWERDOWN>;

+STMicroelectronics STi family Sysconfig Peripheral SoftReset Controller
+=============================================================================
+
+This binding describes a reset controller device that is used to enable and
+disable on-chip peripheral controllers such as USB and SATA, using
+"softreset" control bits found in the STi family SoC system configuration
+registers.
+
+The actual action taken when softreset is asserted is hardware dependent.
+However, when asserted it may not be possible to access the hardware's
+registers and after an assert/deassert sequence the hardware's previous state
+may no longer be valid.
+
+Please refer to reset.txt in this directory for common reset
+controller binding usage.
+
+Required properties:
+- compatible: Should be "st,<chip>-softreset" example:
+ "st,stih415-softreset" or "st,stih416-softreset";
+- #reset-cells: 1, see below
+
+example:
+
+ softreset: softreset-controller {
+ #reset-cells = <1>;
+ compatible = "st,stih415-softreset";
+ };
+
+
+Specifying softreset control of devices
+=======================================
+
+Device nodes should specify the reset channel required in their "resets"
+property, containing a phandle to the softreset device node and an
+index specifying which channel to use, as described in reset.txt
+
+example:
+
+ ethernet0{
+ resets = <&softreset STIH415_ETH0_SOFTRESET>;
+ };
+
+Macro definitions for the supported reset channels can be found in:
+
+include/dt-bindings/reset-controller/stih415-resets.h

+The OMAP Display Subsystem (DSS) hardware consists of DSS Core, DISPC module and
+a number of encoder modules. All DSS versions contain DSS Core and DISPC, but
+the encoder modules vary.
+
+The DSS Core is the parent of the other DSS modules, and manages clock routing,
+integration to the SoC, etc.
+
+DISPC is the display controller, which reads pixels from the memory and outputs
+a RGB pixel stream to encoders.
+
+The encoder modules encode the received RGB pixel stream to a video output like
+HDMI, MIPI DPI, etc.
+
+Video Ports
+-----------
+
+The DSS Core and the encoders have video port outputs. The structure of the
+video ports is described in Documentation/devicetree/bindings/video/video-
+ports.txt, and the properties for the ports and endpoints for each encoder are
+described in the SoC's DSS binding documentation.
+
+The video ports are used to describe the connections to external hardware, like
+panels or external encoders.
+
+Aliases
+-------
+
+The board dts file may define aliases for displays to assign "displayX" style
+name for each display. If no aliases are defined, a semi-random number is used
+for the display.
+
+Example
+-------
+
+A shortened example of the DSS description for OMAP4, with non-relevant parts
+removed, defined in omap4.dtsi:
+

+ reg = <0x58000000 0x80>;

+ clock-names = "fck";
+ #address-cells = <1>;
+ #size-cells = <1>;
+ ranges;
+
+ dispc@58001000 {
+ compatible = "ti,omap4-dispc";
+ reg = <0x58001000 0x1000>;
+ interrupts = <GIC_SPI 25 IRQ_TYPE_LEVEL_HIGH>;

+};
+
+A shortened example of the board description for OMAP4 Panda board, defined in
+omap4-panda.dts.
+
+The Panda board has a DVI and a HDMI connector, and the board contains a TFP410
+chip (MIPI DPI to DVI encoder) and a TPD12S015 chip (HDMI ESD protection & level
+shifter). The video pipelines for the connectors are formed as follows:
+
+DSS Core --(MIPI DPI)--> TFP410 --(DVI)--> DVI Connector
+OMAP HDMI --(HDMI)--> TPD12S015 --(HDMI)--> HDMI Connector

+GPIO drivers providing IRQs
+---------------------------
+It is custom that GPIO drivers (GPIO chips) are also providing interrupts,
+most often cascaded off a parent interrupt controller, and in some special
+cases the GPIO logic is melded with a SoC's primary interrupt controller.
+
+The IRQ portions of the GPIO block are implemented using an irqchip, using
+the header <linux/irq.h>. So basically such a driver is utilizing two sub-
+systems simultaneously: gpio and irq.
+
+It is legal for any IRQ consumer to request an IRQ from any irqchip no matter
+if that is a combined GPIO+IRQ driver. The basic premise is that gpio_chip and
+irq_chip are orthogonal, and offering their services independent of each
+other.
+
+gpiod_to_irq() is just a convenience function to figure out the IRQ for a
+certain GPIO line and should not be relied upon to have been called before
+the IRQ is used.
+
+So always prepare the hardware and make it ready for action in respective
+callbacks from the GPIO and irqchip APIs. Do not rely on gpiod_to_irq() having
+been called first.
+
+This orthogonality leads to ambiguities that we need to solve: if there is
+competition inside the subsystem which side is using the resource (a certain
+GPIO line and register for example) it needs to deny certain operations and
+keep track of usage inside of the gpiolib subsystem. This is why the API
+below exists.

+disabled by the user or due to an fatal error, internal kmemleak objects
+won't be freed when kmemleak is disabled, and those objects may occupy

+
+6. RapidIO Bus Controllers/Ports
+--------------------------------
+
+On-chip RapidIO controllers and PCIe-to-RapidIO bridges (referenced as
+"Master Port" or "mport") are presented in sysfs as the special class of
+devices: "rapidio_port".
+
+The /sys/class/rapidio_port subdirectory contains individual subdirectories
+named as "rapidioN" where N = mport ID registered with RapidIO subsystem.
+
+NOTE: An mport ID is not a RapidIO destination ID assigned to a given local
+mport device.
+
+Each mport device subdirectory in addition to standard entries contains the
+following device-specific attributes:
+
+ port_destid - reports RapidIO destination ID assigned to the given RapidIO
+ mport device. If value 0xFFFFFFFF is returned this means that
+ no valid destination ID have been assigned to the mport (yet).
+ Normally, before enumeration/discovery have been executed only
+ fabric enumerating mports have a valid destination ID assigned
+ to them using "hdid=..." rapidio module parameter.
+ sys_size - reports RapidIO common transport system size:
+ 0 = small (8-bit destination ID, max. 256 devices),
+ 1 = large (16-bit destination ID, max. 65536 devices).
+
+After enumeration or discovery was performed for a given mport device,
+the corresponding subdirectory will also contain subdirectories for each
+child RapidIO device connected to the mport. Naming conventions for RapidIO
+devices are described in Section 1 above.
+
+The example below shows mport device subdirectory with several child RapidIO
+devices attached to it.

- * C code. "Emulation" is where the original instruction is rewritten
- * and executed, often by altering its registers.
- *
- * By having all behavior of the kprobe'd instruction completed before
- * returning from the kprobe_handler(), all locks (scheduler and
- * interrupt) can safely be released. There is no need for secondary
- * breakpoints, no race with MP or preemptable kernels, nor having to
- * clean up resources counts at a later time impacting overall system
- * performance. By rewriting the instruction, only the minimum registers
- * need to be loaded and saved back optimizing performance.
- *
- * Calling the insnslot_*_rwflags version of a function doesn't hurt
- * anything even when the CPSR flags aren't updated by the
- * instruction. It's just a little slower in return for saving
- * a little space by not having a duplicate function that doesn't
- * update the flags. (The same optimization can be said for
- * instructions that do or don't perform register writeback)
- * Also, instructions can either read the flags, only write the
- * flags, or read and write the flags. To save combinations
- * rather than for sheer performance, flag functions just assume
- * read and write of flags.

-/*
- * The following definitions and macros are used to build instruction
- * decoding tables for use by kprobe_decode_insn.
- *
- * These tables are a concatenation of entries each of which consist of one of
- * the decode_* structs. All of the fields in every type of decode structure
- * are of the union type decode_item, therefore the entire decode table can be
- * viewed as an array of these and declared like:
- *
- * static const union decode_item table_name[] = {};
- *
- * In order to construct each entry in the table, macros are used to
- * initialise a number of sequential decode_item values in a layout which
- * matches the relevant struct. E.g. DECODE_SIMULATE initialise a struct
- * decode_simulate by initialising four decode_item objects like this...
- *
- * {.bits = _type},
- * {.bits = _mask},
- * {.bits = _value},
- * {.handler = _handler},
- *
- * Initialising a specified member of the union means that the compiler
- * will produce a warning if the argument is of an incorrect type.
- *
- * Below is a list of each of the macros used to initialise entries and a
- * description of the action performed when that entry is matched to an
- * instruction. A match is found when (instruction & mask) == value.
- *
- * DECODE_TABLE(mask, value, table)
- * Instruction decoding jumps to parsing the new sub-table 'table'.
- *
- * DECODE_CUSTOM(mask, value, decoder)
- * The custom function 'decoder' is called to the complete decoding
- * of an instruction.
- *
- * DECODE_SIMULATE(mask, value, handler)
- * Set the probes instruction handler to 'handler', this will be used
- * to simulate the instruction when the probe is hit. Decoding returns
- * with INSN_GOOD_NO_SLOT.
- *
- * DECODE_EMULATE(mask, value, handler)
- * Set the probes instruction handler to 'handler', this will be used
- * to emulate the instruction when the probe is hit. The modified
- * instruction (see below) is placed in the probes instruction slot so it
- * may be called by the emulation code. Decoding returns with INSN_GOOD.
- *
- * DECODE_REJECT(mask, value)
- * Instruction decoding fails with INSN_REJECTED
- *
- * DECODE_OR(mask, value)
- * This allows the mask/value test of multiple table entries to be
- * logically ORed. Once an 'or' entry is matched the decoding action to
- * be performed is that of the next entry which isn't an 'or'. E.g.
- *
- * DECODE_OR (mask1, value1)
- * DECODE_OR (mask2, value2)
- * DECODE_SIMULATE (mask3, value3, simulation_handler)
- *
- * This means that if any of the three mask/value pairs match the
- * instruction being decoded, then 'simulation_handler' will be used
- * for it.
- *
- * Both the SIMULATE and EMULATE macros have a second form which take an
- * additional 'regs' argument.
- *
- * DECODE_SIMULATEX(mask, value, handler, regs)
- * DECODE_EMULATEX (mask, value, handler, regs)
- *
- * These are used to specify what kind of CPU register is encoded in each of the
- * least significant 5 nibbles of the instruction being decoded. The regs value
- * is specified using the REGS macro, this takes any of the REG_TYPE_* values
- * from enum decode_reg_type as arguments; only the '*' part of the name is
- * given. E.g.
- *
- * REGS(0, ANY, NOPC, 0, ANY)
- *
- * This indicates an instruction is encoded like:
- *
- * bits 19..16 ignore
- * bits 15..12 any register allowed here
- * bits 11.. 8 any register except PC allowed here
- * bits 7.. 4 ignore
- * bits 3.. 0 any register allowed here
- *
- * This register specification is checked after a decode table entry is found to
- * match an instruction (through the mask/value test). Any invalid register then
- * found in the instruction will cause decoding to fail with INSN_REJECTED. In
- * the above example this would happen if bits 11..8 of the instruction were
- * 1111, indicating R15 or PC.
- *
- * As well as checking for legal combinations of registers, this data is also
- * used to modify the registers encoded in the instructions so that an
- * emulation routines can use it. (See decode_regs() and INSN_NEW_BITS.)
- *
- * Here is a real example which matches ARM instructions of the form
- * "AND <Rd>,<Rn>,<Rm>,<shift> <Rs>"
- *
- * DECODE_EMULATEX (0x0e000090, 0x00000010, emulate_rd12rn16rm0rs8_rwflags,
- * REGS(ANY, ANY, NOPC, 0, ANY)),
- * ^ ^ ^ ^
- * Rn Rd Rs Rm
- *
- * Decoding the instruction "AND R4, R5, R6, ASL R15" will be rejected because
- * Rs == R15
- *
- * Decoding the instruction "AND R4, R5, R6, ASL R7" will be accepted and the
- * instruction will be modified to "AND R0, R2, R3, ASL R1" and then placed into
- * the kprobes instruction slot. This can then be called later by the handler
- * function emulate_rd12rn16rm0rs8_rwflags in order to simulate the instruction.

+ * To avoid the complications of mimicing single-stepping on a
+ * processor without a Next-PC or a single-step mode, and to
+ * avoid having to deal with the side-effects of boosting, we
+ * simulate or emulate (almost) all ARM instructions.
+ *
+ * "Simulation" is where the instruction's behavior is duplicated in
+ * C code. "Emulation" is where the original instruction is rewritten
+ * and executed, often by altering its registers.
+ *
+ * By having all behavior of the kprobe'd instruction completed before
+ * returning from the kprobe_handler(), all locks (scheduler and
+ * interrupt) can safely be released. There is no need for secondary
+ * breakpoints, no race with MP or preemptable kernels, nor having to
+ * clean up resources counts at a later time impacting overall system
+ * performance. By rewriting the instruction, only the minimum registers
+ * need to be loaded and saved back optimizing performance.
+ *
+ * Calling the insnslot_*_rwflags version of a function doesn't hurt
+ * anything even when the CPSR flags aren't updated by the
+ * instruction. It's just a little slower in return for saving
+ * a little space by not having a duplicate function that doesn't
+ * update the flags. (The same optimization can be said for
+ * instructions that do or don't perform register writeback)
+ * Also, instructions can either read the flags, only write the
+ * flags, or read and write the flags. To save combinations
+ * rather than for sheer performance, flag functions just assume
+ * read and write of flags.

+ * The following definitions and macros are used to build instruction
+ * decoding tables for use by probes_decode_insn.
+ *
+ * These tables are a concatenation of entries each of which consist of one of
+ * the decode_* structs. All of the fields in every type of decode structure
+ * are of the union type decode_item, therefore the entire decode table can be
+ * viewed as an array of these and declared like:
+ *
+ * static const union decode_item table_name[] = {};
+ *
+ * In order to construct each entry in the table, macros are used to
+ * initialise a number of sequential decode_item values in a layout which
+ * matches the relevant struct. E.g. DECODE_SIMULATE initialise a struct
+ * decode_simulate by initialising four decode_item objects like this...
+ *
+ * {.bits = _type},
+ * {.bits = _mask},
+ * {.bits = _value},
+ * {.action = _handler},
+ *
+ * Initialising a specified member of the union means that the compiler
+ * will produce a warning if the argument is of an incorrect type.
+ *
+ * Below is a list of each of the macros used to initialise entries and a
+ * description of the action performed when that entry is matched to an
+ * instruction. A match is found when (instruction & mask) == value.
+ *
+ * DECODE_TABLE(mask, value, table)
+ * Instruction decoding jumps to parsing the new sub-table 'table'.
+ *
+ * DECODE_CUSTOM(mask, value, decoder)
+ * The value of 'decoder' is used as an index into the array of
+ * action functions, and the retrieved decoder function is invoked
+ * to complete decoding of the instruction.
+ *
+ * DECODE_SIMULATE(mask, value, handler)
+ * The probes instruction handler is set to the value found by
+ * indexing into the action array using the value of 'handler'. This
+ * will be used to simulate the instruction when the probe is hit.
+ * Decoding returns with INSN_GOOD_NO_SLOT.
+ *
+ * DECODE_EMULATE(mask, value, handler)
+ * The probes instruction handler is set to the value found by
+ * indexing into the action array using the value of 'handler'. This
+ * will be used to emulate the instruction when the probe is hit. The
+ * modified instruction (see below) is placed in the probes instruction
+ * slot so it may be called by the emulation code. Decoding returns
+ * with INSN_GOOD.
+ *
+ * DECODE_REJECT(mask, value)
+ * Instruction decoding fails with INSN_REJECTED
+ *
+ * DECODE_OR(mask, value)
+ * This allows the mask/value test of multiple table entries to be
+ * logically ORed. Once an 'or' entry is matched the decoding action to
+ * be performed is that of the next entry which isn't an 'or'. E.g.
+ *
+ * DECODE_OR (mask1, value1)
+ * DECODE_OR (mask2, value2)
+ * DECODE_SIMULATE (mask3, value3, simulation_handler)
+ *
+ * This means that if any of the three mask/value pairs match the
+ * instruction being decoded, then 'simulation_handler' will be used
+ * for it.
+ *
+ * Both the SIMULATE and EMULATE macros have a second form which take an
+ * additional 'regs' argument.
+ *
+ * DECODE_SIMULATEX(mask, value, handler, regs)
+ * DECODE_EMULATEX (mask, value, handler, regs)
+ *
+ * These are used to specify what kind of CPU register is encoded in each of the
+ * least significant 5 nibbles of the instruction being decoded. The regs value
+ * is specified using the REGS macro, this takes any of the REG_TYPE_* values
+ * from enum decode_reg_type as arguments; only the '*' part of the name is
+ * given. E.g.
+ *
+ * REGS(0, ANY, NOPC, 0, ANY)
+ *
+ * This indicates an instruction is encoded like:
+ *
+ * bits 19..16 ignore
+ * bits 15..12 any register allowed here
+ * bits 11.. 8 any register except PC allowed here
+ * bits 7.. 4 ignore
+ * bits 3.. 0 any register allowed here
+ *
+ * This register specification is checked after a decode table entry is found to
+ * match an instruction (through the mask/value test). Any invalid register then
+ * found in the instruction will cause decoding to fail with INSN_REJECTED. In
+ * the above example this would happen if bits 11..8 of the instruction were
+ * 1111, indicating R15 or PC.
+ *
+ * As well as checking for legal combinations of registers, this data is also
+ * used to modify the registers encoded in the instructions so that an
+ * emulation routines can use it. (See decode_regs() and INSN_NEW_BITS.)
+ *
+ * Here is a real example which matches ARM instructions of the form
+ * "AND <Rd>,<Rn>,<Rm>,<shift> <Rs>"
+ *
+ * DECODE_EMULATEX (0x0e000090, 0x00000010, PROBES_DATA_PROCESSING_REG,
+ * REGS(ANY, ANY, NOPC, 0, ANY)),
+ * ^ ^ ^ ^
+ * Rn Rd Rs Rm
+ *
+ * Decoding the instruction "AND R4, R5, R6, ASL R15" will be rejected because
+ * Rs == R15
+ *
+ * Decoding the instruction "AND R4, R5, R6, ASL R7" will be accepted and the
+ * instruction will be modified to "AND R0, R2, R3, ASL R1" and then placed into
+ * the kprobes instruction slot. This can then be called later by the handler
+ * function emulate_rd12rn16rm0rs8_rwflags (a pointer to which is retrieved from
+ * the indicated slot in the action array), in order to simulate the instruction.

+ * Each clock can have zero, one, or two dividers which change the

+ * variable. If there are two dividers, they are the "pre-divider"
+ * and the "regular" or "downstream" divider. If there is only one,
+ * there is no pre-divider.
+ *
+ * A fixed divider is any non-zero (positive) value, and it
+ * indicates how the input rate is affected by the divider.
+ *
+ * The value of a variable divider is maintained in a sub-field of a
+ * 32-bit divider register. The position of the field in the
+ * register is defined by its offset and width. The value recorded
+ * in this field is always 1 less than the value it represents.
+ *
+ * In addition, a variable divider can indicate that some subset
+ * of its bits represent a "fractional" part of the divider. Such
+ * bits comprise the low-order portion of the divider field, and can
+ * be viewed as representing the portion of the divider that lies to
+ * the right of the decimal point. Most variable dividers have zero
+ * fractional bits. Variable dividers with non-zero fraction width
+ * still record a value 1 less than the value they represent; the
+ * added 1 does *not* affect the low-order bit in this case, it
+ * affects the bits above the fractional part only. (Often in this
+ * code a divider field value is distinguished from the value it
+ * represents by referring to the latter as a "divisor".)
+ *
+ * In order to avoid dealing with fractions, divider arithmetic is
+ * performed using "scaled" values. A scaled value is one that's
+ * been left-shifted by the fractional width of a divider. Dividing
+ * a scaled value by a scaled divisor produces the desired quotient
+ * without loss of precision and without any other special handling
+ * for fractions.
+ *
+ * The recorded value of a variable divider can be modified. To
+ * modify either divider (or both), a clock must be enabled (i.e.,
+ * using its gate). In addition, a trigger register (described
+ * below) must be used to commit the change, and polled to verify

+ * QCOM BAM DMA engine driver
+ *
+ * QCOM BAM DMA blocks are distributed amongst a number of the on-chip
+ * peripherals on the MSM 8x74. The configuration of the channels are dependent
+ * on the way they are hard wired to that specific peripheral. The peripheral
+ * device tree entries specify the configuration of each channel.
+ *
+ * The DMA controller requires the use of external memory for storage of the
+ * hardware descriptors for each channel. The descriptor FIFO is accessed as a
+ * circular buffer and operations are managed according to the offset within the
+ * FIFO. After pipe/channel reset, all of the pipe registers and internal state
+ * are back to defaults.
+ *
+ * During DMA operations, we write descriptors to the FIFO, being careful to
+ * handle wrapping and then write the last FIFO offset to that channel's
+ * P_EVNT_REG register to kick off the transaction. The P_SW_OFSTS register
+ * indicates the current FIFO offset that is being processed, so there is some
+ * indication of where the hardware is currently working.

+/**
+ * DOC: Overview
+ *
+ * drm_mm provides a simple range allocator. The drivers are free to use the
+ * resource allocator from the linux core if it suits them, the upside of drm_mm
+ * is that it's in the DRM core. Which means that it's easier to extend for
+ * some of the crazier special purpose needs of gpus.
+ *
+ * The main data struct is &drm_mm, allocations are tracked in &drm_mm_node.
+ * Drivers are free to embed either of them into their own suitable
+ * datastructures. drm_mm itself will not do any allocations of its own, so if
+ * drivers choose not to embed nodes they need to still allocate them
+ * themselves.
+ *
+ * The range allocator also supports reservation of preallocated blocks. This is
+ * useful for taking over initial mode setting configurations from the firmware,
+ * where an object needs to be created which exactly matches the firmware's
+ * scanout target. As long as the range is still free it can be inserted anytime
+ * after the allocator is initialized, which helps with avoiding looped
+ * depencies in the driver load sequence.
+ *
+ * drm_mm maintains a stack of most recently freed holes, which of all
+ * simplistic datastructures seems to be a fairly decent approach to clustering
+ * allocations and avoiding too much fragmentation. This means free space
+ * searches are O(num_holes). Given that all the fancy features drm_mm supports
+ * something better would be fairly complex and since gfx thrashing is a fairly
+ * steep cliff not a real concern. Removing a node again is O(1).
+ *
+ * drm_mm supports a few features: Alignment and range restrictions can be
+ * supplied. Further more every &drm_mm_node has a color value (which is just an
+ * opaqua unsigned long) which in conjunction with a driver callback can be used
+ * to implement sophisticated placement restrictions. The i915 DRM driver uses
+ * this to implement guard pages between incompatible caching domains in the
+ * graphics TT.
+ *
+ * Two behaviors are supported for searching and allocating: bottom-up and top-down.
+ * The default is bottom-up. Top-down allocation can be used if the memory area
+ * has different restrictions, or just to reduce fragmentation.
+ *
+ * Finally iteration helpers to walk all nodes and all holes are provided as are
+ * some basic allocator dumpers for debugging.

+/**
+ * DOC: i915 batch buffer command parser
+ *
+ * Motivation:
+ * Certain OpenGL features (e.g. transform feedback, performance monitoring)
+ * require userspace code to submit batches containing commands such as
+ * MI_LOAD_REGISTER_IMM to access various registers. Unfortunately, some
+ * generations of the hardware will noop these commands in "unsecure" batches
+ * (which includes all userspace batches submitted via i915) even though the
+ * commands may be safe and represent the intended programming model of the
+ * device.
+ *
+ * The software command parser is similar in operation to the command parsing
+ * done in hardware for unsecure batches. However, the software parser allows
+ * some operations that would be noop'd by hardware, if the parser determines
+ * the operation is safe, and submits the batch as "secure" to prevent hardware
+ * parsing.
+ *
+ * Threats:
+ * At a high level, the hardware (and software) checks attempt to prevent
+ * granting userspace undue privileges. There are three categories of privilege.
+ *
+ * First, commands which are explicitly defined as privileged or which should
+ * only be used by the kernel driver. The parser generally rejects such
+ * commands, though it may allow some from the drm master process.
+ *
+ * Second, commands which access registers. To support correct/enhanced
+ * userspace functionality, particularly certain OpenGL extensions, the parser
+ * provides a whitelist of registers which userspace may safely access (for both
+ * normal and drm master processes).
+ *
+ * Third, commands which access privileged memory (i.e. GGTT, HWS page, etc).
+ * The parser always rejects such commands.
+ *
+ * The majority of the problematic commands fall in the MI_* range, with only a
+ * few specific commands on each ring (e.g. PIPE_CONTROL and MI_FLUSH_DW).
+ *
+ * Implementation:
+ * Each ring maintains tables of commands and registers which the parser uses in
+ * scanning batch buffers submitted to that ring.
+ *
+ * Since the set of commands that the parser must check for is significantly
+ * smaller than the number of commands supported, the parser tables contain only
+ * those commands required by the parser. This generally works because command
+ * opcode ranges have standard command length encodings. So for commands that
+ * the parser does not need to check, it can easily skip them. This is
+ * implementated via a per-ring length decoding vfunc.
+ *
+ * Unfortunately, there are a number of commands that do not follow the standard
+ * length encoding for their opcode range, primarily amongst the MI_* commands.
+ * To handle this, the parser provides a way to define explicit "skip" entries
+ * in the per-ring command tables.
+ *
+ * Other command table entries map fairly directly to high level categories
+ * mentioned above: rejected, master-only, register whitelist. The parser
+ * implements a number of checks, including the privileged memory checks, via a
+ * general bitmasking mechanism.

- * This struct tracks the state needed for the Package C8+ feature.
+ * This struct helps tracking the state needed for runtime PM, which puts the
+ * device in PCI D3 state. Notice that when this happens, nothing on the
+ * graphics device works, even register access, so we don't get interrupts nor
+ * anything else.
*
- * Package states C8 and deeper are really deep PC states that can only be
- * reached when all the devices on the system allow it, so even if the graphics
- * device allows PC8+, it doesn't mean the system will actually get to these
- * states.
+ * Every piece of our code that needs to actually touch the hardware needs to
+ * either call intel_runtime_pm_get or call intel_display_power_get with the
+ * appropriate power domain.
*
- * Our driver only allows PC8+ when all the outputs are disabled, the power well
- * is disabled and the GPU is idle. When these conditions are met, we manually
- * do the other conditions: disable the interrupts, clocks and switch LCPLL
- * refclk to Fclk.
- *
- * When we really reach PC8 or deeper states (not just when we allow it) we lose
- * the state of some registers, so when we come back from PC8+ we need to
- * restore this state. We don't get into PC8+ if we're not in RC6, so we don't
- * need to take care of the registers kept by RC6.
- *
- * The interrupt disabling is part of the requirements. We can only leave the
- * PCH HPD interrupts enabled. If we're in PC8+ and we get another interrupt we
- * can lock the machine.
- *
- * Ideally every piece of our code that needs PC8+ disabled would call
- * hsw_disable_package_c8, which would increment disable_count and prevent the
- * system from reaching PC8+. But we don't have a symmetric way to do this for
- * everything, so we have the requirements_met and gpu_idle variables. When we
- * switch requirements_met or gpu_idle to true we decrease disable_count, and
- * increase it in the opposite case. The requirements_met variable is true when
- * all the CRTCs, encoders and the power well are disabled. The gpu_idle
- * variable is true when the GPU is idle.
- *
- * In addition to everything, we only actually enable PC8+ if disable_count
- * stays at zero for at least some seconds. This is implemented with the
- * enable_work variable. We do this so we don't enable/disable PC8 dozens of
- * consecutive times when all screens are disabled and some background app
- * queries the state of our connectors, or we have some application constantly
- * waking up to use the GPU. Only after the enable_work function actually
- * enables PC8+ the "enable" variable will become true, which means that it can
- * be false even if disable_count is 0.
+ * Our driver uses the autosuspend delay feature, which means we'll only really
+ * suspend if we stay with zero refcount for a certain amount of time. The
+ * default value is currently very conservative (see intel_init_runtime_pm), but
+ * it can be changed with the standard runtime PM files from sysfs.

+* (3) both long and short but short preferred and long only when necesarry
+*
+* These modes must be selected compile time via compile switches.
+* Compile switch settings for the diffrent modes:

+* (2) DRXDAPFASI_LONG_ADDR_ALLOWED=1, DRXDAPFASI_SHORT_ADDR_ALLOWED=0
+* (3) DRXDAPFASI_LONG_ADDR_ALLOWED=1, DRXDAPFASI_SHORT_ADDR_ALLOWED=1
+*
+* The default setting will be (3) both long and short.
+* The default setting will need no compile switches.
+* The default setting must be overridden if compile switches are already
+* defined.

+/*
+* Comments about DRXDAP_MAX_WCHUNKSIZE in single or multi master mode and
+* in combination with short and long addressing format. All text below
+* assumes long addressing format. The table also includes information
+* for short ADDRessing format.
+*
+* In single master mode, data can be written by sending the register address
+* first, then two or four bytes of data in the next packet.
+* Because the device address plus a register address equals five bytes,
+* the mimimum chunk size must be five.
+* If ten-bit I2C device addresses are used, the minimum chunk size must be six,
+* because the I2C device address will then occupy two bytes when writing.
+*
+* Data in single master mode is transferred as follows:
+* <S> <devW> a0 a1 a2 a3 <P>
+* <S> <devW> d0 d1 [d2 d3] <P>
+* ..
+* or
+* ..
+* <S> <devW> a0 a1 a2 a3 <P>
+* <S> <devR> --- <P>
+*
+* In multi-master mode, the data must immediately follow the address (an I2C
+* stop resets the internal address), and hence the minimum chunk size is
+* 1 <I2C address> + 4 (register address) + 2 (data to send) = 7 bytes (8 if
+* 10-bit I2C device addresses are used).
+*
+* The 7-bit or 10-bit i2c address parameters is a runtime parameter.
+* The other parameters can be limited via compile time switches.

+ NTSC/FM AGCs
+
+ Four AGCs are used for NTSC:
+ (1) RF (used to attenuate the input signal in case of to much power)
+ (2) IF (used to attenuate the input signal in case of to much power)
+ (3) Video AGC (used to amplify the output signal in case input to low)
+ (4) SIF AGC (used to amplify the output signal in case input to low)
+
+ Video AGC is coupled to RF and IF. SIF AGC is not coupled. It is assumed
+ that the coupling between Video AGC and the RF and IF AGCs also works in
+ favor of the SIF AGC.
+
+ Three AGCs are used for FM:
+ (1) RF (used to attenuate the input signal in case of to much power)
+ (2) IF (used to attenuate the input signal in case of to much power)
+ (3) SIF AGC (used to amplify the output signal in case input to low)
+
+ The SIF AGC is now coupled to the RF/IF AGCs.
+ The SIF AGC is needed for both SIF ouput and the internal SIF signal to
+ the AUD block.
+
+ RF and IF AGCs DACs are part of AFE, Video and SIF AGC DACs are part of
+ the ATV block. The AGC control algorithms are all implemented in
+ microcode.
+
+ ATV SETTINGS
+
+ (Shadow settings will not be used for now, they will be implemented
+ later on because of the schedule)
+
+ Several HW/SCU "settings" can be used for ATV. The standard selection
+ will reset most of these settings. To avoid that the end user apllication
+ has to perform these settings each time the ATV or FM standards is
+ selected the driver will shadow these settings. This enables the end user
+ to perform the settings only once after a drx_open(). The driver must
+ write the shadow settings to HW/SCU incase:
+ ( setstandard FM/ATV) ||
+ ( settings have changed && FM/ATV standard is active)
+ The shadow settings will be stored in the device specific data container.
+ A set of flags will be defined to flag changes in shadow settings.
+ A routine will be implemented to write all changed shadow settings to
+ HW/SCU.
+
+ The "settings" will consist of: AGC settings, filter settings etc.
+
+ Disadvantage of use of shadow settings:
+ Direct changes in HW/SCU registers will not be reflected in the
+ shadow settings and these changes will be overwritten during a next
+ update. This can happen during evaluation. This will not be a problem
+ for normal customer usage.

- bool "Assume MMC/SD cards are non-removable (DANGEROUS)"
- help
- If you say Y here, the MMC layer will assume that all cards
- stayed in their respective slots during the suspend. The
- normal behaviour is to remove them at suspend and
- redetecting them at resume. Breaking this assumption will
- in most cases result in data corruption.
-
- This option is usually just for embedded systems which use
- a MMC/SD card for rootfs. Most people should say N here.
-
- This option sets a default which can be overridden by the
- module parameter "removable=0" or "removable=1".

+ This option enables read-only UBI block devices support. UBI block
+ devices will be layered on top of UBI volumes, which means that the
+ UBI driver will transparently handle things like bad eraseblocks and
+ bit-flips. You can put any block-oriented file system on top of UBI
+ volumes in read-only mode (e.g., ext4), but it is probably most
+ practical for read-only file systems, like squashfs.
+
+ When selected, this feature will be built in the UBI driver.
+
+ If in doubt, say "N".

+- find and remove any code for other chips that is left over

+- find codes that can use %pM and %Nph formatting

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

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

+ * or may not have worked. We only guaranteed unmap granularity
+ * matching the original mapping; even though it was untracked here,
+ * the original mappings are reflected in IOMMU mappings. This
+ * resulted in a couple unusual behaviors. First, if a range is not
+ * able to be unmapped, ex. a set of 4k pages that was mapped as a

+ * This also returns success and the returned unmap size reflects the
+ * actual size unmapped.
+ *
+ * We attempt to maintain compatibility with this "v1" interface, but
+ * we take control out of the hands of the IOMMU. Therefore, an unmap
+ * request offset from the beginning of the original mapping will
+ * return success with zero sized unmap. And an unmap request covering
+ * the first iova of mapping will unmap the entire range.
+ *
+ * The v2 version of this interface intends to be more deterministic.
+ * Unmap requests must fully cover previous mappings. Multiple
+ * mappings may still be unmaped by specifying large ranges, but there
+ * must not be any previous mappings bisected by the range. An error

+/*
+ * Lock descriptions and usage:
+ *
+ * Each hash chain of both the block and index hash tables now contains
+ * a built-in lock used to serialize accesses to the hash chain.
+ *
+ * Accesses to global data structures mb_cache_list and mb_cache_lru_list
+ * are serialized via the global spinlock mb_cache_spinlock.
+ *
+ * Each mb_cache_entry contains a spinlock, e_entry_lock, to serialize
+ * accesses to its local data, such as e_used and e_queued.
+ *
+ * Lock ordering:
+ *
+ * Each block hash chain's lock has the highest lock order, followed by an
+ * index hash chain's lock, mb_cache_bg_lock (used to implement mb_cache_entry's
+ * lock), and mb_cach_spinlock, with the lowest order. While holding
+ * either a block or index hash chain lock, a thread can acquire an
+ * mc_cache_bg_lock, which in turn can also acquire mb_cache_spinlock.
+ *
+ * Synchronization:
+ *
+ * Since both mb_cache_entry_get and mb_cache_entry_find scan the block and
+ * index hash chian, it needs to lock the corresponding hash chain. For each
+ * mb_cache_entry within the chain, it needs to lock the mb_cache_entry to
+ * prevent either any simultaneous release or free on the entry and also
+ * to serialize accesses to either the e_used or e_queued member of the entry.
+ *
+ * To avoid having a dangling reference to an already freed
+ * mb_cache_entry, an mb_cache_entry is only freed when it is not on a
+ * block hash chain and also no longer being referenced, both e_used,
+ * and e_queued are 0's. When an mb_cache_entry is explicitly freed it is
+ * first removed from a block hash chain.

+ * Double CLOCK lists
+ *
+ * Per zone, two clock lists are maintained for file pages: the
+ * inactive and the active list. Freshly faulted pages start out at
+ * the head of the inactive list and page reclaim scans pages from the
+ * tail. Pages that are accessed multiple times on the inactive list
+ * are promoted to the active list, to protect them from reclaim,
+ * whereas active pages are demoted to the inactive list when the
+ * active list grows too big.

+ *
+ *
+ * Access frequency and refault distance
+ *
+ * A workload is thrashing when its pages are frequently used but they
+ * are evicted from the inactive list every time before another access
+ * would have promoted them to the active list.
+ *
+ * In cases where the average access distance between thrashing pages
+ * is bigger than the size of memory there is nothing that can be
+ * done - the thrashing set could never fit into memory under any
+ * circumstance.
+ *
+ * However, the average access distance could be bigger than the
+ * inactive list, yet smaller than the size of memory. In this case,
+ * the set could fit into memory if it weren't for the currently
+ * active pages - which may be used more, hopefully less frequently:
+ *
+ * +-memory available to cache-+
+ * | |
+ * +-inactive------+-active----+
+ * a b | c d e f g h i | J K L M N |
+ * +---------------+-----------+
+ *
+ * It is prohibitively expensive to accurately track access frequency
+ * of pages. But a reasonable approximation can be made to measure
+ * thrashing on the inactive list, after which refaulting pages can be
+ * activated optimistically to compete with the existing active pages.
+ *
+ * Approximating inactive page access frequency - Observations:
+ *
+ * 1. When a page is accessed for the first time, it is added to the
+ * head of the inactive list, slides every existing inactive page
+ * towards the tail by one slot, and pushes the current tail page
+ * out of memory.
+ *
+ * 2. When a page is accessed for the second time, it is promoted to
+ * the active list, shrinking the inactive list by one slot. This
+ * also slides all inactive pages that were faulted into the cache
+ * more recently than the activated page towards the tail of the
+ * inactive list.
+ *
+ * Thus:
+ *
+ * 1. The sum of evictions and activations between any two points in
+ * time indicate the minimum number of inactive pages accessed in
+ * between.
+ *
+ * 2. Moving one inactive page N page slots towards the tail of the
+ * list requires at least N inactive page accesses.
+ *
+ * Combining these:
+ *
+ * 1. When a page is finally evicted from memory, the number of
+ * inactive pages accessed while the page was in cache is at least
+ * the number of page slots on the inactive list.
+ *
+ * 2. In addition, measuring the sum of evictions and activations (E)
+ * at the time of a page's eviction, and comparing it to another
+ * reading (R) at the time the page faults back into memory tells
+ * the minimum number of accesses while the page was not cached.
+ * This is called the refault distance.
+ *
+ * Because the first access of the page was the fault and the second
+ * access the refault, we combine the in-cache distance with the
+ * out-of-cache distance to get the complete minimum access distance
+ * of this page:
+ *
+ * NR_inactive + (R - E)
+ *
+ * And knowing the minimum access distance of a page, we can easily
+ * tell if the page would be able to stay in cache assuming all page
+ * slots in the cache were available:
+ *
+ * NR_inactive + (R - E) <= NR_inactive + NR_active
+ *
+ * which can be further simplified to
+ *
+ * (R - E) <= NR_active
+ *
+ * Put into words, the refault distance (out-of-cache) can be seen as
+ * a deficit in inactive list space (in-cache). If the inactive list
+ * had (R - E) more page slots, the page would not have been evicted
+ * in between accesses, but activated instead. And on a full system,
+ * the only thing eating into inactive list space is active pages.
+ *
+ *
+ * Activating refaulting pages
+ *
+ * All that is known about the active list is that the pages have been
+ * accessed more than once in the past. This means that at any given
+ * time there is actually a good chance that pages on the active list
+ * are no longer in active use.
+ *
+ * So when a refault distance of (R - E) is observed and there are at
+ * least (R - E) active pages, the refaulting page is activated
+ * optimistically in the hope that (R - E) active pages are actually
+ * used less frequently than the refaulting page - or even not used at
+ * all anymore.
+ *
+ * If this is wrong and demotion kicks in, the pages which are truly
+ * used more frequently will be reactivated while the less frequently
+ * used once will be evicted from memory.
+ *
+ * But if this is right, the stale pages will be pushed out of memory
+ * and the used pages get to stay in cache.
+ *
+ *
+ * Implementation
+ *
+ * For each zone's file LRU lists, a counter for inactive evictions
+ * and activations is maintained (zone->inactive_age).
+ *
+ * On eviction, a snapshot of this counter (along with some bits to
+ * identify the zone) is stored in the now empty page cache radix tree
+ * slot of the evicted page. This is called a shadow entry.
+ *
+ * On cache misses for which there are shadow entries, an eligible
+ * refault distance will immediately activate the refaulting page.
