-You need some entries in /dev for the cciss device. The MAKEDEV script
-can make device nodes for you automatically. Currently the device setup
-is as follows:
-
-Major numbers:
- 104 cciss0
- 105 cciss1
- 106 cciss2
- 105 cciss3
- 108 cciss4
- 109 cciss5
- 110 cciss6
- 111 cciss7
-
-Minor numbers:
- b7 b6 b5 b4 b3 b2 b1 b0
- |----+----| |----+----|
- | |
- | +-------- Partition ID (0=wholedev, 1-15 partition)
- |
- +-------------------- Logical Volume number
-
-The device naming scheme is:
-/dev/cciss/c0d0 Controller 0, disk 0, whole device
-/dev/cciss/c0d0p1 Controller 0, disk 0, partition 1
-/dev/cciss/c0d0p2 Controller 0, disk 0, partition 2
-/dev/cciss/c0d0p3 Controller 0, disk 0, partition 3
-
-/dev/cciss/c1d1 Controller 1, disk 1, whole device
-/dev/cciss/c1d1p1 Controller 1, disk 1, partition 1
-/dev/cciss/c1d1p2 Controller 1, disk 1, partition 2
-/dev/cciss/c1d1p3 Controller 1, disk 1, partition 3
-
-CCISS simple mode support
--------------------------
-
-The "cciss_simple_mode=1" boot parameter may be used to prevent the driver
-from putting the controller into "performant" mode. The difference is that
-with simple mode, each command completion requires an interrupt, while with
-"performant mode" (the default, and ordinarily better performing) it is
-possible to have multiple command completions indicated by a single
-interrupt.
-
-SCSI tape drive and medium changer support
-------------------------------------------
-
-SCSI sequential access devices and medium changer devices are supported and
-appropriate device nodes are automatically created. (e.g.
-/dev/st0, /dev/st1, etc. See the "st" man page for more details.)
-You must enable "SCSI tape drive support for Smart Array 5xxx" and
-"SCSI support" in your kernel configuration to be able to use SCSI
-tape drives with your Smart Array 5xxx controller.
-
-Additionally, note that the driver will engage the SCSI core at init
-time if any tape drives or medium changers are detected. The driver may
-also be directed to dynamically engage the SCSI core via the /proc filesystem
-entry which the "block" side of the driver creates as
-/proc/driver/cciss/cciss* at runtime. This is best done via a script.
-
-For example:
-
- for x in /proc/driver/cciss/cciss[0-9]*
- do
- echo "engage scsi" > $x
- done
-
-Once the SCSI core is engaged by the driver, it cannot be disengaged
-(except by unloading the driver, if it happens to be linked as a module.)
-
-Note also that if no sequential access devices or medium changers are
-detected, the SCSI core will not be engaged by the action of the above
-script.
-
-Hot plug support for SCSI tape drives
--------------------------------------
-
-Hot plugging of SCSI tape drives is supported, with some caveats.
-The cciss driver must be informed that changes to the SCSI bus
-have been made. This may be done via the /proc filesystem.
-For example:
-
- echo "rescan" > /proc/scsi/cciss0/1
-
-This causes the driver to query the adapter about changes to the
-physical SCSI buses and/or fibre channel arbitrated loop and the
-driver to make note of any new or removed sequential access devices
-or medium changers. The driver will output messages indicating what
-devices have been added or removed and the controller, bus, target and
-lun used to address the device. It then notifies the SCSI mid layer
-of these changes.
-
-Note that the naming convention of the /proc filesystem entries
-contains a number in addition to the driver name. (E.g. "cciss0"
-instead of just "cciss" which you might expect.)
-
-Note: ONLY sequential access devices and medium changers are presented
-as SCSI devices to the SCSI mid layer by the cciss driver. Specifically,
-physical SCSI disk drives are NOT presented to the SCSI mid layer. The
-physical SCSI disk drives are controlled directly by the array controller
-hardware and it is important to prevent the kernel from attempting to directly
-access these devices too, as if the array controller were merely a SCSI
-controller in the same way that we are allowing it to access SCSI tape drives.
-
-SCSI error handling for tape drives and medium changers
--------------------------------------------------------
-
-The linux SCSI mid layer provides an error handling protocol which
-kicks into gear whenever a SCSI command fails to complete within a
-certain amount of time (which can vary depending on the command).
-The cciss driver participates in this protocol to some extent. The
-normal protocol is a four step process. First the device is told
-to abort the command. If that doesn't work, the device is reset.
-If that doesn't work, the SCSI bus is reset. If that doesn't work
-the host bus adapter is reset. Because the cciss driver is a block
-driver as well as a SCSI driver and only the tape drives and medium
-changers are presented to the SCSI mid layer, and unlike more
-straightforward SCSI drivers, disk i/o continues through the block
-side during the SCSI error recovery process, the cciss driver only
-implements the first two of these actions, aborting the command, and
-resetting the device. Additionally, most tape drives will not oblige
-in aborting commands, and sometimes it appears they will not even
-obey a reset command, though in most circumstances they will. In
-the case that the command cannot be aborted and the device cannot be
-reset, the device will be set offline.
-
-In the event the error handling code is triggered and a tape drive is
-successfully reset or the tardy command is successfully aborted, the
-tape drive may still not allow i/o to continue until some command
-is issued which positions the tape to a known position. Typically you
-must rewind the tape (by issuing "mt -f /dev/st0 rewind" for example)
-before i/o can proceed again to a tape drive which was reset.
-
-There is a cciss_tape_cmds module parameter which can be used to make cciss
-allocate more commands for use by tape drives. Ordinarily only a few commands
-(6) are allocated for tape drives because tape drives are slow and
-infrequently used and the primary purpose of Smart Array controllers is to
-act as a RAID controller for disk drives, so the vast majority of commands
-are allocated for disk devices. However, if you have more than a few tape
-drives attached to a smart array, the default number of commands may not be
-enough (for example, if you have 8 tape drives, you could only rewind 6
-at one time with the default number of commands.) The cciss_tape_cmds module
-parameter allows more commands (up to 16 more) to be allocated for use by
-tape drives. For example:
-
- insmod cciss.ko cciss_tape_cmds=16
-
-Or, as a kernel boot parameter passed in via grub: cciss.cciss_tape_cmds=8

-stdout-path property
---------------------
+
+kaslr-seed
+-----------
+
+This property is used when booting with CONFIG_RANDOMIZE_BASE as the
+entropy used to randomize the kernel image base address location. Since
+it is used directly, this value is intended only for KASLR, and should
+not be used for other purposes (as it may leak information about KASLR

+/ {
+ chosen {
+ kaslr-seed = <0xfeedbeef 0xc0def00d>;
+ };
+};
+
+Note that if this property is set from UEFI (or a bootloader in EFI
+mode) when EFI_RNG_PROTOCOL is supported, it will be overwritten by
+the Linux EFI stub (which will populate the property itself, using
+EFI_RNG_PROTOCOL).
+
+stdout-path
+-----------
Device trees may specify the device to be used for boot console output
with a stdout-path property under /chosen, as described in the Devicetree

+If you connect an oscillator to both the USB_XTAL and USB_EXTAL, this module
+is not needed because this is default setting. (Of course, you can set the
+clock rates to both "usb_extal" and "usb_xtal" nodes.
+
+Case 1: An external clock connects to R-Car SoC
+ +----------+ +--- R-Car ---------------------+
+ |External |---|USB_EXTAL ---> all usb channels|
+ |clock | |USB_XTAL |
+ +----------+ +-------------------------------+
+In this case, we need this driver with "usb_extal" clock.
+
+Case 2: An oscillator connects to R-Car SoC
+ +----------+ +--- R-Car ---------------------+
+ |Oscillator|---|USB_EXTAL -+-> all usb channels|
+ | |---|USB_XTAL --+ |
+ +----------+ +-------------------------------+
+In this case, we don't need this selector.

+STMicroelectronics STM32H7 Reset and Clock Controller
+=====================================================
+
+The RCC IP is both a reset and a clock controller.
+
+Please refer to clock-bindings.txt for common clock controller binding usage.
+Please also refer to reset.txt for common reset controller binding usage.
+
+Required properties:
+- compatible: Should be:
+ "st,stm32h743-rcc"
+
+- reg: should be register base and length as documented in the
+ datasheet
+
+- #reset-cells: 1, see below
+
+- #clock-cells : from common clock binding; shall be set to 1
+
+- clocks: External oscillator clock phandle
+ - high speed external clock signal (HSE)
+ - low speed external clock signal (LSE)
+ - external I2S clock (I2S_CKIN)
+
+Optional properties:
+- st,syscfg: phandle for pwrcfg, mandatory to disable/enable backup domain
+ write protection (RTC clock).
+
+Example:
+
+ rcc: reset-clock-controller@58024400 {
+ compatible = "st,stm32h743-rcc", "st,stm32-rcc";
+ reg = <0x58024400 0x400>;
+ #reset-cells = <1>;
+ #clock-cells = <2>;
+ clocks = <&clk_hse>, <&clk_lse>, <&clk_i2s_ckin>;
+
+ st,syscfg = <&pwrcfg>;
+};
+
+The peripheral clock consumer should specify the desired clock by
+having the clock ID in its "clocks" phandle cell.
+
+Example:
+
+ timer5: timer@40000c00 {
+ compatible = "st,stm32-timer";
+ reg = <0x40000c00 0x400>;
+ interrupts = <50>;
+ clocks = <&rcc TIM5_CK>;
+ };
+
+Specifying softreset control of devices
+=======================================
+
+Device nodes should specify the reset channel required in their "resets"
+property, containing a phandle to the reset device node and an index specifying
+which channel to use.
+The index is the bit number within the RCC registers bank, starting from RCC
+base address.
+It is calculated as: index = register_offset / 4 * 32 + bit_offset.
+Where bit_offset is the bit offset within the register.
+
+For example, for CRC reset:
+ crc = AHB4RSTR_offset / 4 * 32 + CRCRST_bit_offset = 0x88 / 4 * 32 + 19 = 1107
+
+Example:
+
+ timer2 {
+ resets = <&rcc STM32H7_APB1L_RESET(TIM2)>;
+ };

+* QCOM IOMMU v1 Implementation
+
+Qualcomm "B" family devices which are not compatible with arm-smmu have
+a similar looking IOMMU but without access to the global register space,
+and optionally requiring additional configuration to route context irqs
+to non-secure vs secure interrupt line.
+
+** Required properties:
+
+- compatible : Should be one of:
+
+ "qcom,msm8916-iommu"
+
+ Followed by "qcom,msm-iommu-v1".
+
+- clock-names : Should be a pair of "iface" (required for IOMMUs
+ register group access) and "bus" (required for
+ the IOMMUs underlying bus access).
+
+- clocks : Phandles for respective clocks described by
+ clock-names.
+
+- #address-cells : must be 1.
+
+- #size-cells : must be 1.
+
+- #iommu-cells : Must be 1. Index identifies the context-bank #.
+
+- ranges : Base address and size of the iommu context banks.
+
+- qcom,iommu-secure-id : secure-id.
+
+- List of sub-nodes, one per translation context bank. Each sub-node
+ has the following required properties:
+
+ - compatible : Should be one of:
+ - "qcom,msm-iommu-v1-ns" : non-secure context bank
+ - "qcom,msm-iommu-v1-sec" : secure context bank
+ - reg : Base address and size of context bank within the iommu
+ - interrupts : The context fault irq.
+
+** Optional properties:
+
+- reg : Base address and size of the SMMU local base, should
+ be only specified if the iommu requires configuration
+ for routing of context bank irq's to secure vs non-
+ secure lines. (Ie. if the iommu contains secure
+ context banks)

+Pincontrol driver for RK805 Power management IC.
+
+RK805 has 2 pins which can be configured as GPIO output only.
+
+Please refer file <devicetree/bindings/pinctrl/pinctrl-bindings.txt>
+for details of the common pinctrl bindings used by client devices,
+including the meaning of the phrase "pin configuration node".
+
+Optional Pinmux properties:
+--------------------------
+Following properties are required if default setting of pins are required
+at boot.
+- pinctrl-names: A pinctrl state named per <pinctrl-binding.txt>.
+- pinctrl[0...n]: Properties to contain the phandle for pinctrl states per
+ <pinctrl-binding.txt>.
+
+The pin configurations are defined as child of the pinctrl states node. Each
+sub-node have following properties:
+
+Required properties:
+------------------
+- #gpio-cells: Should be two. The first cell is the pin number and the
+ second is the GPIO flags.
+
+- gpio-controller: Marks the device node as a GPIO controller.
+
+- pins: List of pins. Valid values of pins properties are: gpio0, gpio1.
+
+First 2 properties must be added in the RK805 PMIC node, documented in
+Documentation/devicetree/bindings/mfd/rk808.txt
+
+Optional properties:
+-------------------
+Following are optional properties defined as pinmux DT binding document
+<pinctrl-bindings.txt>. Absence of properties will leave the configuration
+on default.
+ function,
+ output-low,
+ output-high.
+
+Valid values for function properties are: gpio.
+
+Theres is also not customised properties for any GPIO.
+
+Example:
+--------

+ compatible = "rockchip,rk805";
+ ...
+ gpio-controller;
+ #gpio-cells = <2>;

+TI Davinci DSP devices
+=======================
+
+Binding status: Unstable - Subject to changes for DT representation of clocks
+ and resets
+
+The TI Davinci family of SoCs usually contains a TI DSP Core sub-system that
+is used to offload some of the processor-intensive tasks or algorithms, for
+achieving various system level goals.
+
+The processor cores in the sub-system usually contain additional sub-modules
+like L1 and/or L2 caches/SRAMs, an Interrupt Controller, an external memory
+controller, a dedicated local power/sleep controller etc. The DSP processor
+core used in Davinci SoCs is usually a C674x DSP CPU.
+
+DSP Device Node:
+================
+Each DSP Core sub-system is represented as a single DT node.
+
+Required properties:
+--------------------
+The following are the mandatory properties:
+
+- compatible: Should be one of the following,
+ "ti,da850-dsp" for DSPs on OMAP-L138 SoCs
+
+- reg: Should contain an entry for each value in 'reg-names'.
+ Each entry should have the memory region's start address
+ and the size of the region, the representation matching
+ the parent node's '#address-cells' and '#size-cells' values.
+
+- reg-names: Should contain strings with the following names, each
+ representing a specific internal memory region or a
+ specific register space,
+ "l2sram", "l1pram", "l1dram", "host1cfg", "chipsig_base"
+
+- interrupts: Should contain the interrupt number used to receive the
+ interrupts from the DSP. The value should follow the
+ interrupt-specifier format as dictated by the
+ 'interrupt-parent' node.
+
+- memory-region: phandle to the reserved memory node to be associated
+ with the remoteproc device. The reserved memory node
+ can be a CMA memory node, and should be defined as
+ per the bindings in
+ Documentation/devicetree/bindings/reserved-memory/reserved-memory.txt
+
+Optional properties:
+--------------------
+- interrupt-parent: phandle to the interrupt controller node. This property
+ is needed if the device node hierarchy doesn't have an
+ interrupt controller.
+
+
+Example:
+--------
+
+ /* DSP Reserved Memory node */
+ reserved-memory {
+ #address-cells = <1>;
+ #size-cells = <1>;
+ ranges;
+
+ dsp_memory_region: dsp-memory@c3000000 {

- reg: physical base address of the controller and length of memory mapped
region
+Optional properties:
+
+ - aspeed,reset-type = "cpu|soc|system|none"
+
+ Reset behavior - Whenever a timeout occurs the watchdog can be programmed
+ to generate one of three different, mutually exclusive, types of resets.
+
+ Type "none" can be specified to indicate that no resets are to be done.
+ This is useful in situations where another watchdog engine on chip is
+ to perform the reset.
+
+ If 'aspeed,reset-type=' is not specfied the default is to enable system
+ reset.
+
+ Reset types:
+
+ - cpu: Reset CPU on watchdog timeout
+
+ - soc: Reset 'System on Chip' on watchdog timeout
+
+ - system: Reset system on watchdog timeout
+
+ - none: No reset is performed on timeout. Assumes another watchdog
+ engine is responsible for this.
+
+ - aspeed,alt-boot: If property is present then boot from alternate block.
+ - aspeed,external-signal: If property is present then signal is sent to
+ external reset counter (only WDT1 and WDT2). If not
+ specified no external signal is sent.
+ - aspeed,ext-pulse-duration: External signal pulse duration in microseconds
+
+Optional properties for AST2500-compatible watchdogs:
+ - aspeed,ext-push-pull: If aspeed,external-signal is present, set the pin's
+ drive type to push-pull. The default is open-drain.
+ - aspeed,ext-active-high: If aspeed,external-signal is present and and the pin
+ is configured as push-pull, then set the pulse
+ polarity to active-high. The default is active-low.
+
Example:

+CEC Pin framework
+-----------------
+
+Most CEC hardware operates on full CEC messages where the software provides
+the message and the hardware handles the low-level CEC protocol. But some
+hardware only drives the CEC pin and software has to handle the low-level
+CEC protocol. The CEC pin framework was created to handle such devices.

+Note that due to the close-to-realtime requirements it can never be guaranteed

+CEC Notifier framework
+----------------------
+
+Most drm HDMI implementations have an integrated CEC implementation and no
+notifier support is needed. But some have independent CEC implementations
+that have their own driver. This could be an IP block for an SoC or a
+completely separate chip that deals with the CEC pin. For those cases a
+drm driver can install a notifier and use the notifier to inform the
+CEC driver about changes in the physical address.

+Stopping the transmitter
+^^^^^^^^^^^^^^^^^^^^^^^^

+A transmitter stops sending the stream of images as a result of
+calling the ``.s_stream()`` callback. Some transmitters may stop the
+stream at a frame boundary whereas others stop immediately,
+effectively leaving the current frame unfinished. The receiver driver
+should not make assumptions either way, but function properly in both

-=======================

+Property types

Tuning into a Digital TV physical channel and starting decoding it
requires changing a set of parameters, in order to control the tuner,
the demodulator, the Linear Low-noise Amplifier (LNA) and to set the
-antenna subsystem via Satellite Equipment Control (SEC), on satellite
-systems. The actual parameters are specific to each particular digital
+antenna subsystem via Satellite Equipment Control - SEC (on satellite
+systems). The actual parameters are specific to each particular digital
TV standards, and may change as the digital TV specs evolves.
-In the past, the strategy used was to have a union with the parameters
-needed to tune for DVB-S, DVB-C, DVB-T and ATSC delivery systems grouped
-there. The problem is that, as the second generation standards appeared,
-those structs were not big enough to contain the additional parameters.
-Also, the union didn't have any space left to be expanded without
-breaking userspace. So, the decision was to deprecate the legacy
-union/struct based approach, in favor of a properties set approach.
+In the past (up to DVB API version 3 - DVBv3), the strategy used was to have a
+union with the parameters needed to tune for DVB-S, DVB-C, DVB-T and
+ATSC delivery systems grouped there. The problem is that, as the second
+generation standards appeared, the size of such union was not big
+enough to group the structs that would be required for those new
+standards. Also, extending it would break userspace.
+
+So, the legacy union/struct based approach was deprecated, in favor
+of a properties set approach. On such approach,
+:ref:`FE_GET_PROPERTY and FE_SET_PROPERTY <FE_GET_PROPERTY>` are used
+to setup the frontend and read its status.
+
+The actual action is determined by a set of dtv_property cmd/data pairs.
+With one single ioctl, is possible to get/set up to 64 properties.
+
+This section describes the new and recommended way to set the frontend,
+with supports all digital TV delivery systems.
.. note::
- On Linux DVB API version 3, setting a frontend were done via
- struct :c:type:`dvb_frontend_parameters`.
- This got replaced on version 5 (also called "S2API", as this API were
- added originally_enabled to provide support for DVB-S2), because the
- old API has a very limited support to new standards and new hardware.
- This section describes the new and recommended way to set the frontend,
- with suppports all digital TV delivery systems.
+ 1. On Linux DVB API version 3, setting a frontend was done via
+ struct :c:type:`dvb_frontend_parameters`.
-Example: with the properties based approach, in order to set the tuner
-to a DVB-C channel at 651 kHz, modulated with 256-QAM, FEC 3/4 and
-symbol rate of 5.217 Mbauds, those properties should be sent to
+ 2. Don't use DVB API version 3 calls on hardware with supports
+ newer standards. Such API provides no suport or a very limited
+ support to new standards and/or new hardware.
+
+ 3. Nowadays, most frontends support multiple delivery systems.
+ Only with DVB API version 5 calls it is possible to switch between
+ the multiple delivery systems supported by a frontend.
+
+ 4. DVB API version 5 is also called *S2API*, as the first
+ new standard added to it was DVB-S2.
+
+**Example**: in order to set the hardware to tune into a DVB-C channel
+at 651 kHz, modulated with 256-QAM, FEC 3/4 and symbol rate of 5.217
+Mbauds, those properties should be sent to

+ c2 = (2413 / 4096) * 32
+
+ c3 = (2392 / 4096) * 32
+
+Transfer function:
+ L' = ((c1 + c2 * L\ :sup:`m1`) / (1 + c3 * L\ :sup:`m1`))\ :sup:`m2`
+
+Inverse Transfer function:
+ L = (max(L':sup:`1/m2` - c1, 0) / (c2 - c3 *
+ L'\ :sup:`1/m2`))\ :sup:`1/m1`
+
+Take care when converting between this transfer function and non-HDR transfer
+functions: the linear RGB values [0…1] of HDR content map to a luminance range
+of 0 to 10000 cd/m\ :sup:`2` whereas the linear RGB values of non-HDR (aka
+Standard Dynamic Range or SDR) map to a luminance range of 0 to 100 cd/m\ :sup:`2`.
+
+To go from SDR to HDR you will have to divide L by 100 first. To go in the other
+direction you will have to multiply L by 100. Of course, this clamps all
+luminance values over 100 cd/m\ :sup:`2` to 100 cd/m\ :sup:`2`.
+
+There are better methods, see e.g. :ref:`colimg` for more in-depth information
+about this.

+12-bit packed Bayer formats
+
+
+Description
+===========
+
+These four pixel formats are packed raw sRGB / Bayer formats with 12
+bits per colour. Every two consecutive samples are packed into three
+bytes. Each of the first two bytes contain the 8 high order bits of
+the pixels, and the third byte contains the four least significants
+bits of each pixel, in the same order.
+
+Each n-pixel row contains n/2 green samples and n/2 blue or red
+samples, with alternating green-red and green-blue rows. They are
+conventionally described as GRGR... BGBG..., RGRG... GBGB..., etc.
+Below is an example of a small V4L2_PIX_FMT_SBGGR12P image:
+
+**Byte Order.**
+Each cell is one byte.

+Qualcomm Camera Subsystem driver
+================================
+
+Introduction
+------------
+
+This file documents the Qualcomm Camera Subsystem driver located under
+drivers/media/platform/qcom/camss-8x16.
+
+The current version of the driver supports the Camera Subsystem found on
+Qualcomm MSM8916 and APQ8016 processors.
+
+The driver implements V4L2, Media controller and V4L2 subdev interfaces.
+Camera sensor using V4L2 subdev interface in the kernel is supported.
+
+The driver is implemented using as a reference the Qualcomm Camera Subsystem
+driver for Android as found in Code Aurora [#f1]_.
+
+
+Qualcomm Camera Subsystem hardware
+----------------------------------
+
+The Camera Subsystem hardware found on 8x16 processors and supported by the
+driver consists of:
+
+- 2 CSIPHY modules. They handle the Physical layer of the CSI2 receivers.
+ A separate camera sensor can be connected to each of the CSIPHY module;
+- 2 CSID (CSI Decoder) modules. They handle the Protocol and Application layer
+ of the CSI2 receivers. A CSID can decode data stream from any of the CSIPHY.
+ Each CSID also contains a TG (Test Generator) block which can generate
+ artificial input data for test purposes;
+- ISPIF (ISP Interface) module. Handles the routing of the data streams from
+ the CSIDs to the inputs of the VFE;
+- VFE (Video Front End) module. Contains a pipeline of image processing hardware
+ blocks. The VFE has different input interfaces. The PIX (Pixel) input
+ interface feeds the input data to the image processing pipeline. The image
+ processing pipeline contains also a scale and crop module at the end. Three
+ RDI (Raw Dump Interface) input interfaces bypass the image processing
+ pipeline. The VFE also contains the AXI bus interface which writes the output
+ data to memory.
+
+
+Supported functionality
+-----------------------
+
+The current version of the driver supports:
+
+- Input from camera sensor via CSIPHY;
+- Generation of test input data by the TG in CSID;
+- RDI interface of VFE - raw dump of the input data to memory.
+
+ Supported formats:
+
+ - YUYV/UYVY/YVYU/VYUY (packed YUV 4:2:2 - V4L2_PIX_FMT_YUYV /
+ V4L2_PIX_FMT_UYVY / V4L2_PIX_FMT_YVYU / V4L2_PIX_FMT_VYUY);
+ - MIPI RAW8 (8bit Bayer RAW - V4L2_PIX_FMT_SRGGB8 /
+ V4L2_PIX_FMT_SGRBG8 / V4L2_PIX_FMT_SGBRG8 / V4L2_PIX_FMT_SBGGR8);
+ - MIPI RAW10 (10bit packed Bayer RAW - V4L2_PIX_FMT_SBGGR10P /
+ V4L2_PIX_FMT_SGBRG10P / V4L2_PIX_FMT_SGRBG10P / V4L2_PIX_FMT_SRGGB10P);
+ - MIPI RAW12 (12bit packed Bayer RAW - V4L2_PIX_FMT_SRGGB12P /
+ V4L2_PIX_FMT_SGBRG12P / V4L2_PIX_FMT_SGRBG12P / V4L2_PIX_FMT_SRGGB12P).
+
+- PIX interface of VFE
+
+ - Format conversion of the input data.
+
+ Supported input formats:
+
+ - YUYV/UYVY/YVYU/VYUY (packed YUV 4:2:2 - V4L2_PIX_FMT_YUYV /
+ V4L2_PIX_FMT_UYVY / V4L2_PIX_FMT_YVYU / V4L2_PIX_FMT_VYUY).
+
+ Supported output formats:
+
+ - NV12/NV21 (two plane YUV 4:2:0 - V4L2_PIX_FMT_NV12 / V4L2_PIX_FMT_NV21);
+ - NV16/NV61 (two plane YUV 4:2:2 - V4L2_PIX_FMT_NV16 / V4L2_PIX_FMT_NV61).
+
+ - Scaling support. Configuration of the VFE Encoder Scale module
+ for downscalling with ratio up to 16x.
+
+ - Cropping support. Configuration of the VFE Encoder Crop module.
+
+- Concurrent and independent usage of two data inputs - could be camera sensors
+ and/or TG.
+
+
+Driver Architecture and Design
+------------------------------
+
+The driver implements the V4L2 subdev interface. With the goal to model the
+hardware links between the modules and to expose a clean, logical and usable
+interface, the driver is split into V4L2 sub-devices as follows:
+
+- 2 CSIPHY sub-devices - each CSIPHY is represented by a single sub-device;
+- 2 CSID sub-devices - each CSID is represented by a single sub-device;
+- 2 ISPIF sub-devices - ISPIF is represented by a number of sub-devices equal
+ to the number of CSID sub-devices;
+- 4 VFE sub-devices - VFE is represented by a number of sub-devices equal to
+ the number of the input interfaces (3 RDI and 1 PIX).
+
+The considerations to split the driver in this particular way are as follows:
+
+- representing CSIPHY and CSID modules by a separate sub-device for each module
+ allows to model the hardware links between these modules;
+- representing VFE by a separate sub-devices for each input interface allows
+ to use the input interfaces concurently and independently as this is
+ supported by the hardware;
+- representing ISPIF by a number of sub-devices equal to the number of CSID
+ sub-devices allows to create linear media controller pipelines when using two
+ cameras simultaneously. This avoids branches in the pipelines which otherwise
+ will require a) userspace and b) media framework (e.g. power on/off
+ operations) to make assumptions about the data flow from a sink pad to a
+ source pad on a single media entity.
+
+Each VFE sub-device is linked to a separate video device node.
+
+The media controller pipeline graph is as follows (with connected two OV5645
+camera sensors):

+
+.. kernel-figure:: qcom_camss_graph.dot
+ :alt: qcom_camss_graph.dot
+ :align: center
+
+ Media pipeline graph
+
+
+Implementation
+--------------
+
+Runtime configuration of the hardware (updating settings while streaming) is
+not required to implement the currently supported functionality. The complete
+configuration on each hardware module is applied on STREAMON ioctl based on
+the current active media links, formats and controls set.
+
+The output size of the scaler module in the VFE is configured with the actual
+compose selection rectangle on the sink pad of the 'msm_vfe0_pix' entity.
+
+The crop output area of the crop module in the VFE is configured with the actual
+crop selection rectangle on the source pad of the 'msm_vfe0_pix' entity.

+Cached rbtrees
+--------------
+
+Computing the leftmost (smallest) node is quite a common task for binary
+search trees, such as for traversals or users relying on a the particular
+order for their own logic. To this end, users can use 'struct rb_root_cached'
+to optimize O(logN) rb_first() calls to a simple pointer fetch avoiding
+potentially expensive tree iterations. This is done at negligible runtime
+overhead for maintanence; albeit larger memory footprint.
+
+Similar to the rb_root structure, cached rbtrees are initialized to be
+empty via:
+
+ struct rb_root_cached mytree = RB_ROOT_CACHED;
+
+Cached rbtree is simply a regular rb_root with an extra pointer to cache the
+leftmost node. This allows rb_root_cached to exist wherever rb_root does,
+which permits augmented trees to be supported as well as only a few extra
+interfaces:
+
+ struct rb_node *rb_first_cached(struct rb_root_cached *tree);
+ void rb_insert_color_cached(struct rb_node *, struct rb_root_cached *, bool);
+ void rb_erase_cached(struct rb_node *node, struct rb_root_cached *);
+
+Both insert and erase calls have their respective counterpart of augmented
+trees:
+
+ void rb_insert_augmented_cached(struct rb_node *node, struct rb_root_cached *,
+ bool, struct rb_augment_callbacks *);
+ void rb_erase_augmented_cached(struct rb_node *, struct rb_root_cached *,
+ struct rb_augment_callbacks *);

+Heterogeneous Memory Management (HMM)
+
+Transparently allow any component of a program to use any memory region of said
+program with a device without using device specific memory allocator. This is
+becoming a requirement to simplify the use of advance heterogeneous computing
+where GPU, DSP or FPGA are use to perform various computations.
+
+This document is divided as follow, in the first section i expose the problems
+related to the use of a device specific allocator. The second section i expose
+the hardware limitations that are inherent to many platforms. The third section
+gives an overview of HMM designs. The fourth section explains how CPU page-
+table mirroring works and what is HMM purpose in this context. Fifth section
+deals with how device memory is represented inside the kernel. Finaly the last
+section present the new migration helper that allow to leverage the device DMA
+engine.
+
+
+1) Problems of using device specific memory allocator:
+2) System bus, device memory characteristics
+3) Share address space and migration
+4) Address space mirroring implementation and API
+5) Represent and manage device memory from core kernel point of view
+6) Migrate to and from device memory
+7) Memory cgroup (memcg) and rss accounting
+
+
+-------------------------------------------------------------------------------
+
+1) Problems of using device specific memory allocator:
+
+Device with large amount of on board memory (several giga bytes) like GPU have
+historically manage their memory through dedicated driver specific API. This
+creates a disconnect between memory allocated and managed by device driver and
+regular application memory (private anonymous, share memory or regular file
+back memory). From here on i will refer to this aspect as split address space.
+I use share address space to refer to the opposite situation ie one in which
+any memory region can be use by device transparently.
+
+Split address space because device can only access memory allocated through the
+device specific API. This imply that all memory object in a program are not
+equal from device point of view which complicate large program that rely on a
+wide set of libraries.
+
+Concretly this means that code that wants to leverage device like GPU need to
+copy object between genericly allocated memory (malloc, mmap private/share/)
+and memory allocated through the device driver API (this still end up with an
+mmap but of the device file).
+
+For flat dataset (array, grid, image, ...) this isn't too hard to achieve but
+complex data-set (list, tree, ...) are hard to get right. Duplicating a complex
+data-set need to re-map all the pointer relations between each of its elements.
+This is error prone and program gets harder to debug because of the duplicate
+data-set.
+
+Split address space also means that library can not transparently use data they
+are getting from core program or other library and thus each library might have
+to duplicate its input data-set using specific memory allocator. Large project
+suffer from this and waste resources because of the various memory copy.
+
+Duplicating each library API to accept as input or output memory allocted by
+each device specific allocator is not a viable option. It would lead to a
+combinatorial explosions in the library entry points.
+
+Finaly with the advance of high level language constructs (in C++ but in other
+language too) it is now possible for compiler to leverage GPU or other devices
+without even the programmer knowledge. Some of compiler identified patterns are
+only do-able with a share address. It is as well more reasonable to use a share
+address space for all the other patterns.
+
+
+-------------------------------------------------------------------------------
+
+2) System bus, device memory characteristics
+
+System bus cripple share address due to few limitations. Most system bus only
+allow basic memory access from device to main memory, even cache coherency is
+often optional. Access to device memory from CPU is even more limited, most
+often than not it is not cache coherent.
+
+If we only consider the PCIE bus than device can access main memory (often
+through an IOMMU) and be cache coherent with the CPUs. However it only allows
+a limited set of atomic operation from device on main memory. This is worse
+in the other direction the CPUs can only access a limited range of the device
+memory and can not perform atomic operations on it. Thus device memory can not
+be consider like regular memory from kernel point of view.
+
+Another crippling factor is the limited bandwidth (~32GBytes/s with PCIE 4.0
+and 16 lanes). This is 33 times less that fastest GPU memory (1 TBytes/s).
+The final limitation is latency, access to main memory from the device has an
+order of magnitude higher latency than when the device access its own memory.
+
+Some platform are developing new system bus or additions/modifications to PCIE
+to address some of those limitations (OpenCAPI, CCIX). They mainly allow two
+way cache coherency between CPU and device and allow all atomic operations the
+architecture supports. Saddly not all platform are following this trends and
+some major architecture are left without hardware solutions to those problems.
+
+So for share address space to make sense not only we must allow device to
+access any memory memory but we must also permit any memory to be migrated to
+device memory while device is using it (blocking CPU access while it happens).
+
+
+-------------------------------------------------------------------------------
+
+3) Share address space and migration
+
+HMM intends to provide two main features. First one is to share the address
+space by duplication the CPU page table into the device page table so same
+address point to same memory and this for any valid main memory address in
+the process address space.
+
+To achieve this, HMM offer a set of helpers to populate the device page table
+while keeping track of CPU page table updates. Device page table updates are
+not as easy as CPU page table updates. To update the device page table you must
+allow a buffer (or use a pool of pre-allocated buffer) and write GPU specifics
+commands in it to perform the update (unmap, cache invalidations and flush,
+...). This can not be done through common code for all device. Hence why HMM
+provides helpers to factor out everything that can be while leaving the gory
+details to the device driver.
+
+The second mechanism HMM provide is a new kind of ZONE_DEVICE memory that does
+allow to allocate a struct page for each page of the device memory. Those page
+are special because the CPU can not map them. They however allow to migrate
+main memory to device memory using exhisting migration mechanism and everything
+looks like if page was swap out to disk from CPU point of view. Using a struct
+page gives the easiest and cleanest integration with existing mm mechanisms.
+Again here HMM only provide helpers, first to hotplug new ZONE_DEVICE memory
+for the device memory and second to perform migration. Policy decision of what
+and when to migrate things is left to the device driver.
+
+Note that any CPU access to a device page trigger a page fault and a migration
+back to main memory ie when a page backing an given address A is migrated from
+a main memory page to a device page then any CPU access to address A trigger a
+page fault and initiate a migration back to main memory.
+
+
+With this two features, HMM not only allow a device to mirror a process address
+space and keeps both CPU and device page table synchronize, but also allow to
+leverage device memory by migrating part of data-set that is actively use by a
+device.
+
+
+-------------------------------------------------------------------------------
+
+4) Address space mirroring implementation and API
+
+Address space mirroring main objective is to allow to duplicate range of CPU
+page table into a device page table and HMM helps keeping both synchronize. A
+device driver that want to mirror a process address space must start with the
+registration of an hmm_mirror struct:
+
+ int hmm_mirror_register(struct hmm_mirror *mirror,
+ struct mm_struct *mm);
+ int hmm_mirror_register_locked(struct hmm_mirror *mirror,
+ struct mm_struct *mm);
+
+The locked variant is to be use when the driver is already holding the mmap_sem
+of the mm in write mode. The mirror struct has a set of callback that are use
+to propagate CPU page table:
+
+ struct hmm_mirror_ops {
+ /* sync_cpu_device_pagetables() - synchronize page tables
+ *
+ * @mirror: pointer to struct hmm_mirror
+ * @update_type: type of update that occurred to the CPU page table
+ * @start: virtual start address of the range to update
+ * @end: virtual end address of the range to update
+ *
+ * This callback ultimately originates from mmu_notifiers when the CPU
+ * page table is updated. The device driver must update its page table
+ * in response to this callback. The update argument tells what action
+ * to perform.
+ *
+ * The device driver must not return from this callback until the device
+ * page tables are completely updated (TLBs flushed, etc); this is a
+ * synchronous call.
+ */
+ void (*update)(struct hmm_mirror *mirror,
+ enum hmm_update action,
+ unsigned long start,
+ unsigned long end);
+ };
+
+Device driver must perform update to the range following action (turn range
+read only, or fully unmap, ...). Once driver callback returns the device must
+be done with the update.
+
+
+When device driver wants to populate a range of virtual address it can use
+either:
+ int hmm_vma_get_pfns(struct vm_area_struct *vma,
+ struct hmm_range *range,
+ unsigned long start,
+ unsigned long end,
+ hmm_pfn_t *pfns);
+ int hmm_vma_fault(struct vm_area_struct *vma,
+ struct hmm_range *range,
+ unsigned long start,
+ unsigned long end,
+ hmm_pfn_t *pfns,
+ bool write,
+ bool block);
+
+First one (hmm_vma_get_pfns()) will only fetch present CPU page table entry and
+will not trigger a page fault on missing or non present entry. The second one
+do trigger page fault on missing or read only entry if write parameter is true.
+Page fault use the generic mm page fault code path just like a CPU page fault.
+
+Both function copy CPU page table into their pfns array argument. Each entry in
+that array correspond to an address in the virtual range. HMM provide a set of
+flags to help driver identify special CPU page table entries.
+
+Locking with the update() callback is the most important aspect the driver must
+respect in order to keep things properly synchronize. The usage pattern is :
+
+ int driver_populate_range(...)
+ {
+ struct hmm_range range;
+ ...
+ again:
+ ret = hmm_vma_get_pfns(vma, &range, start, end, pfns);
+ if (ret)
+ return ret;
+ take_lock(driver->update);
+ if (!hmm_vma_range_done(vma, &range)) {
+ release_lock(driver->update);
+ goto again;
+ }
+
+ // Use pfns array content to update device page table
+
+ release_lock(driver->update);
+ return 0;
+ }
+
+The driver->update lock is the same lock that driver takes inside its update()
+callback. That lock must be call before hmm_vma_range_done() to avoid any race
+with a concurrent CPU page table update.
+
+HMM implements all this on top of the mmu_notifier API because we wanted to a
+simpler API and also to be able to perform optimization latter own like doing
+concurrent device update in multi-devices scenario.
+
+HMM also serve as an impedence missmatch between how CPU page table update are
+done (by CPU write to the page table and TLB flushes) from how device update
+their own page table. Device update is a multi-step process, first appropriate
+commands are write to a buffer, then this buffer is schedule for execution on
+the device. It is only once the device has executed commands in the buffer that
+the update is done. Creating and scheduling update command buffer can happen
+concurrently for multiple devices. Waiting for each device to report commands
+as executed is serialize (there is no point in doing this concurrently).
+
+
+-------------------------------------------------------------------------------
+
+5) Represent and manage device memory from core kernel point of view
+
+Several differents design were try to support device memory. First one use
+device specific data structure to keep information about migrated memory and
+HMM hooked itself in various place of mm code to handle any access to address
+that were back by device memory. It turns out that this ended up replicating
+most of the fields of struct page and also needed many kernel code path to be
+updated to understand this new kind of memory.
+
+Thing is most kernel code path never try to access the memory behind a page
+but only care about struct page contents. Because of this HMM switchted to
+directly using struct page for device memory which left most kernel code path
+un-aware of the difference. We only need to make sure that no one ever try to
+map those page from the CPU side.
+
+HMM provide a set of helpers to register and hotplug device memory as a new
+region needing struct page. This is offer through a very simple API:
+
+ struct hmm_devmem *hmm_devmem_add(const struct hmm_devmem_ops *ops,
+ struct device *device,
+ unsigned long size);
+ void hmm_devmem_remove(struct hmm_devmem *devmem);
+
+The hmm_devmem_ops is where most of the important things are:
+
+ struct hmm_devmem_ops {
+ void (*free)(struct hmm_devmem *devmem, struct page *page);
+ int (*fault)(struct hmm_devmem *devmem,
+ struct vm_area_struct *vma,
+ unsigned long addr,
+ struct page *page,
+ unsigned flags,
+ pmd_t *pmdp);
+ };
+
+The first callback (free()) happens when the last reference on a device page is
+drop. This means the device page is now free and no longer use by anyone. The
+second callback happens whenever CPU try to access a device page which it can
+not do. This second callback must trigger a migration back to system memory.
+
+
+-------------------------------------------------------------------------------
+
+6) Migrate to and from device memory
+
+Because CPU can not access device memory, migration must use device DMA engine
+to perform copy from and to device memory. For this we need a new migration
+helper:
+
+ int migrate_vma(const struct migrate_vma_ops *ops,
+ struct vm_area_struct *vma,
+ unsigned long mentries,
+ unsigned long start,
+ unsigned long end,
+ unsigned long *src,
+ unsigned long *dst,
+ void *private);
+
+Unlike other migration function it works on a range of virtual address, there
+is two reasons for that. First device DMA copy has a high setup overhead cost
+and thus batching multiple pages is needed as otherwise the migration overhead
+make the whole excersie pointless. The second reason is because driver trigger
+such migration base on range of address the device is actively accessing.
+
+The migrate_vma_ops struct define two callbacks. First one (alloc_and_copy())
+control destination memory allocation and copy operation. Second one is there
+to allow device driver to perform cleanup operation after migration.
+
+ struct migrate_vma_ops {
+ void (*alloc_and_copy)(struct vm_area_struct *vma,
+ const unsigned long *src,
+ unsigned long *dst,
+ unsigned long start,
+ unsigned long end,
+ void *private);
+ void (*finalize_and_map)(struct vm_area_struct *vma,
+ const unsigned long *src,
+ const unsigned long *dst,
+ unsigned long start,
+ unsigned long end,
+ void *private);
+ };
+
+It is important to stress that this migration helpers allow for hole in the
+virtual address range. Some pages in the range might not be migrated for all
+the usual reasons (page is pin, page is lock, ...). This helper does not fail
+but just skip over those pages.
+
+The alloc_and_copy() might as well decide to not migrate all pages in the
+range (for reasons under the callback control). For those the callback just
+have to leave the corresponding dst entry empty.
+
+Finaly the migration of the struct page might fails (for file back page) for
+various reasons (failure to freeze reference, or update page cache, ...). If
+that happens then the finalize_and_map() can catch any pages that was not
+migrated. Note those page were still copied to new page and thus we wasted
+bandwidth but this is considered as a rare event and a price that we are
+willing to pay to keep all the code simpler.
+
+
+-------------------------------------------------------------------------------
+
+7) Memory cgroup (memcg) and rss accounting
+
+For now device memory is accounted as any regular page in rss counters (either
+anonymous if device page is use for anonymous, file if device page is use for
+file back page or shmem if device page is use for share memory). This is a
+deliberate choice to keep existing application that might start using device
+memory without knowing about it to keep runing unimpacted.
+
+Drawbacks is that OOM killer might kill an application using a lot of device
+memory and not a lot of regular system memory and thus not freeing much system
+memory. We want to gather more real world experience on how application and
+system react under memory pressure in the presence of device memory before
+deciding to account device memory differently.
+
+
+Same decision was made for memory cgroup. Device memory page are accounted
+against same memory cgroup a regular page would be accounted to. This does
+simplify migration to and from device memory. This also means that migration
+back from device memory to regular memory can not fail because it would
+go above memory cgroup limit. We might revisit this choice latter on once we
+get more experience in how device memory is use and its impact on memory
+resource control.
+
+
+Note that device memory can never be pin nor by device driver nor through GUP
+and thus such memory is always free upon process exit. Or when last reference
+is drop in case of share memory or file back memory.

+ * Rules for modifying this file:
+ * a) Update of this file should typically correspond to a datamanual revision.
+ * Datamanual revision that was used should be updated in comment below.
+ * If there is no update to datamanual, do not update the values. If you
+ * need to use values different from that recommended by the datamanual
+ * for your design, then you should consider adding values to the device-
+ * -tree file for your board directly.
+ * b) We keep the mode names as close to the datamanual as possible. So
+ * if the manual calls a mode, DDR50, or DDR or DDR 1.8v or DDR 3.3v,
+ * we follow that in code too.
+ * c) If the values change between multiple revisions of silicon, we add
+ * a revision tag to both the new and old entry. Use 'rev10' for PG 1.0,
+ * 'rev20' for PG 2.0 and so on.
+ * d) The node name and node label should be the exact same string. This is
+ * to curb naming creativity and achieve consistency.
+ * e) If in future, DRA71x and DRA72x values differ, then add 'dra71_' and
+ * 'dra72_' tag to entries. Both the new and old entries should gain a tag.
+ *
+ * Datamanual Revisions:
+ *

+ * Rules for modifying this file:
+ * a) Update of this file should typically correspond to a datamanual revision.
+ * Datamanual revision that was used should be updated in comment below.
+ * If there is no update to datamanual, do not update the values. If you
+ * need to use values different from that recommended by the datamanual
+ * for your design, then you should consider adding values to the device-
+ * -tree file for your board directly.
+ * b) We keep the mode names as close to the datamanual as possible. So
+ * if the manual calls a mode, DDR50, or DDR or DDR 1.8v or DDR 3.3v,
+ * we follow that in code too.
+ * c) If the values change between multiple revisions of silicon, we add
+ * a revision tag to both the new and old entry. Use 'rev11' for PG 1.1,
+ * 'rev20' for PG 2.0 and so on.
+ * d) The node name and node label should be the exact same string. This is
+ * to curb naming creativity and achieve consistency.
+ *
+ * Datamanual Revisions:
+ *
+ * AM572x Silicon Revision 2.0: SPRS953B, Revised November 2016
+ * AM572x Silicon Revision 1.1: SPRS915R, Revised November 2016

+ * M7memset.S: M7 optimized memset.
+ *
+ * char *memset(sp, c, n)
+ *
+ * Set an array of n chars starting at sp to the character c.
+ * Return sp.
+ *
+ * Fast assembler language version of the following C-program for memset
+ * which represents the `standard' for the C-library.
+ *
+ * void *
+ * memset(void *sp1, int c, size_t n)
+ * {
+ * if (n != 0) {
+ * char *sp = sp1;
+ * do {
+ * *sp++ = (char)c;
+ * } while (--n != 0);
+ * }
+ * return (sp1);
+ * }
+ *
+ * The algorithm is as follows :
+ *
+ * For small 6 or fewer bytes stores, bytes will be stored.
+ *
+ * For less than 32 bytes stores, align the address on 4 byte boundary.
+ * Then store as many 4-byte chunks, followed by trailing bytes.
+ *
+ * For sizes greater than 32 bytes, align the address on 8 byte boundary.
+ * if (count >= 64) {
+ * store 8-bytes chunks to align the address on 64 byte boundary
+ * if (value to be set is zero && count >= MIN_ZERO) {
+ * Using BIS stores, set the first long word of each
+ * 64-byte cache line to zero which will also clear the
+ * other seven long words of the cache line.
+ * }
+ * else if (count >= MIN_LOOP) {
+ * Using BIS stores, set the first long word of each of
+ * ST_CHUNK cache lines (64 bytes each) before the main
+ * loop is entered.
+ * In the main loop, continue pre-setting the first long
+ * word of each cache line ST_CHUNK lines in advance while
+ * setting the other seven long words (56 bytes) of each
+ * cache line until fewer than ST_CHUNK*64 bytes remain.
+ * Then set the remaining seven long words of each cache
+ * line that has already had its first long word set.
+ * }
+ * store remaining data in 64-byte chunks until less than
+ * 64 bytes remain.
+ * }
+ * Store as many 8-byte chunks, followed by trailing bytes.
+ *
+ * BIS = Block Init Store
+ * Doing the advance store of the first element of the cache line
+ * initiates the displacement of a cache line while only using a single
+ * instruction in the pipeline. That avoids various pipeline delays,
+ * such as filling the miss buffer. The performance effect is
+ * similar to prefetching for normal stores.
+ * The special case for zero fills runs faster and uses fewer instruction
+ * cycles than the normal memset loop.
+ *
+ * We only use BIS for memset of greater than MIN_LOOP bytes because a sequence
+ * BIS stores must be followed by a membar #StoreStore. The benefit of
+ * the BIS store must be balanced against the cost of the membar operation.
+ */
+
+/*
+ * ASI_STBI_P marks the cache line as "least recently used"
+ * which means if many threads are active, it has a high chance
+ * of being pushed out of the cache between the first initializing
+ * store and the final stores.
+ * Thus, we use ASI_STBIMRU_P which marks the cache line as
+ * "most recently used" for all but the last store to the cache line.

- * @notify_block: unused
- * @mode: mode we are switching to
- * @unused: unused
- *
- * Used to modify the firmware_class state as we move in between states.
- * The firmware_class implements a firmware cache to enable device driver
- * to fetch firmware upon resume before the root filesystem is ready. We
- * disable API calls which do not use the built-in firmware or the firmware
- * cache when we know these calls will not work.
- *
- * The inner logic behind all this is a bit complex so it is worth summarizing
- * the kernel's own suspend/resume process with context and focus on how this
- * can impact the firmware API.
- *
- * First a review on how we go to suspend::
- *
- * pm_suspend() --> enter_state() -->
- * sys_sync()
- * suspend_prepare() -->
- * __pm_notifier_call_chain(PM_SUSPEND_PREPARE, ...);
- * suspend_freeze_processes() -->
- * freeze_processes() -->
- * __usermodehelper_set_disable_depth(UMH_DISABLED);
- * freeze all tasks ...
- * freeze_kernel_threads()
- * suspend_devices_and_enter() -->
- * dpm_suspend_start() -->
- * dpm_prepare()
- * dpm_suspend()
- * suspend_enter() -->
- * platform_suspend_prepare()
- * dpm_suspend_late()
- * freeze_enter()
- * syscore_suspend()
- *
- * When we resume we bail out of a loop from suspend_devices_and_enter() and
- * unwind back out to the caller enter_state() where we were before as follows::
- *
- * enter_state() -->
- * suspend_devices_and_enter() --> (bail from loop)
- * dpm_resume_end() -->
- * dpm_resume()
- * dpm_complete()
- * suspend_finish() -->
- * suspend_thaw_processes() -->
- * thaw_processes() -->
- * __usermodehelper_set_disable_depth(UMH_FREEZING);
- * thaw_workqueues();
- * thaw all processes ...
- * usermodehelper_enable();
- * pm_notifier_call_chain(PM_POST_SUSPEND);

-notion of how many requests we have outstanding will be wrong most or
-all of the time.
-
-Note, the normal SCSI mid-layer error handling doesn't work well
-for this driver because 1) it takes the io_request_lock before
-calling error handlers and uses a local variable to store flags,
-so the io_request_lock cannot be released and interrupts enabled
-inside the error handlers, and, the error handlers cannot poll
-for command completion because they might get commands from the
-block half of the driver completing, and not know what to do
-with them. That's what we get for making a hybrid scsi/block

+ This enables PCI support for the Intel PCH/PCU SPI controller in
+ master mode. This controller is present in modern Intel hardware
+ and is used to hold BIOS and other persistent settings. Using
+ this driver it is possible to upgrade BIOS directly from Linux.
+
+ Say N here unless you know what you are doing. Overwriting the
+ SPI flash may render the system unbootable.
+
+ To compile this driver as a module, choose M here: the module

+ * Heterogeneous Memory Management (HMM)
+ *
+ * See Documentation/vm/hmm.txt for reasons and overview of what HMM is and it
+ * is for. Here we focus on the HMM API description, with some explanation of
+ * the underlying implementation.
+ *
+ * Short description: HMM provides a set of helpers to share a virtual address
+ * space between CPU and a device, so that the device can access any valid
+ * address of the process (while still obeying memory protection). HMM also
+ * provides helpers to migrate process memory to device memory, and back. Each
+ * set of functionality (address space mirroring, and migration to and from
+ * device memory) can be used independently of the other.
+ *
+ *
+ * HMM address space mirroring API:
+ *
+ * Use HMM address space mirroring if you want to mirror range of the CPU page
+ * table of a process into a device page table. Here, "mirror" means "keep
+ * synchronized". Prerequisites: the device must provide the ability to write-
+ * protect its page tables (at PAGE_SIZE granularity), and must be able to
+ * recover from the resulting potential page faults.
+ *
+ * HMM guarantees that at any point in time, a given virtual address points to
+ * either the same memory in both CPU and device page tables (that is: CPU and
+ * device page tables each point to the same pages), or that one page table (CPU
+ * or device) points to no entry, while the other still points to the old page
+ * for the address. The latter case happens when the CPU page table update
+ * happens first, and then the update is mirrored over to the device page table.
+ * This does not cause any issue, because the CPU page table cannot start
+ * pointing to a new page until the device page table is invalidated.
+ *
+ * HMM uses mmu_notifiers to monitor the CPU page tables, and forwards any
+ * updates to each device driver that has registered a mirror. It also provides
+ * some API calls to help with taking a snapshot of the CPU page table, and to
+ * synchronize with any updates that might happen concurrently.
+ *
+ *
+ * HMM migration to and from device memory:
+ *
+ * HMM provides a set of helpers to hotplug device memory as ZONE_DEVICE, with
+ * a new MEMORY_DEVICE_PRIVATE type. This provides a struct page for each page
+ * of the device memory, and allows the device driver to manage its memory
+ * using those struct pages. Having struct pages for device memory makes
+ * migration easier. Because that memory is not addressable by the CPU it must
+ * never be pinned to the device; in other words, any CPU page fault can always
+ * cause the device memory to be migrated (copied/moved) back to regular memory.
+ *
+ * A new migrate helper (migrate_vma()) has been added (see mm/migrate.c) that
+ * allows use of a device DMA engine to perform the copy operation between
+ * regular system memory and device memory.

+ *
+ * A device driver that is participating in HMM mirroring must always

+ * drivers can decide to register one mirror per device per process, or just
+ * one mirror per process for a group of devices. The pattern is:

+ * if (ret) {
+ * // Cleanup on error
+ * return ret;
+ * }
+ *
+ * // Other device driver specific initialization
+ * ...
+ * }
+ *
+ * Once an hmm_mirror is registered for an address space, the device driver
+ * will get callbacks through sync_cpu_device_pagetables() operation (see

+ *
+ * The alloc_and_copy() callback happens once all source pages have been locked,
+ * unmapped and checked (checked whether pinned or not). All pages that can be
+ * migrated will have an entry in the src array set with the pfn value of the
+ * page and with the MIGRATE_PFN_VALID and MIGRATE_PFN_MIGRATE flag set (other
+ * flags might be set but should be ignored by the callback).
+ *
+ * The alloc_and_copy() callback can then allocate destination memory and copy
+ * source memory to it for all those entries (ie with MIGRATE_PFN_VALID and
+ * MIGRATE_PFN_MIGRATE flag set). Once these are allocated and copied, the
+ * callback must update each corresponding entry in the dst array with the pfn
+ * value of the destination page and with the MIGRATE_PFN_VALID and
+ * MIGRATE_PFN_LOCKED flags set (destination pages must have their struct pages
+ * locked, via lock_page()).
+ *
+ * At this point the alloc_and_copy() callback is done and returns.
+ *
+ * Note that the callback does not have to migrate all the pages that are
+ * marked with MIGRATE_PFN_MIGRATE flag in src array unless this is a migration
+ * from device memory to system memory (ie the MIGRATE_PFN_DEVICE flag is also
+ * set in the src array entry). If the device driver cannot migrate a device
+ * page back to system memory, then it must set the corresponding dst array
+ * entry to MIGRATE_PFN_ERROR. This will trigger a SIGBUS if CPU tries to
+ * access any of the virtual addresses originally backed by this page. Because
+ * a SIGBUS is such a severe result for the userspace process, the device
+ * driver should avoid setting MIGRATE_PFN_ERROR unless it is really in an
+ * unrecoverable state.
+ *
+ * For empty entry inside CPU page table (pte_none() or pmd_none() is true) we
+ * do set MIGRATE_PFN_MIGRATE flag inside the corresponding source array thus
+ * allowing device driver to allocate device memory for those unback virtual
+ * address. For this the device driver simply have to allocate device memory
+ * and properly set the destination entry like for regular migration. Note that
+ * this can still fails and thus inside the device driver must check if the
+ * migration was successful for those entry inside the finalize_and_map()
+ * callback just like for regular migration.
+ *
+ * THE alloc_and_copy() CALLBACK MUST NOT CHANGE ANY OF THE SRC ARRAY ENTRIES
+ * OR BAD THINGS WILL HAPPEN !
+ *
+ *
+ * The finalize_and_map() callback happens after struct page migration from
+ * source to destination (destination struct pages are the struct pages for the
+ * memory allocated by the alloc_and_copy() callback). Migration can fail, and
+ * thus the finalize_and_map() allows the driver to inspect which pages were
+ * successfully migrated, and which were not. Successfully migrated pages will
+ * have the MIGRATE_PFN_MIGRATE flag set for their src array entry.
+ *
+ * It is safe to update device page table from within the finalize_and_map()
+ * callback because both destination and source page are still locked, and the
+ * mmap_sem is held in read mode (hence no one can unmap the range being
+ * migrated).
+ *
+ * Once callback is done cleaning up things and updating its page table (if it
+ * chose to do so, this is not an obligation) then it returns. At this point,
+ * the HMM core will finish up the final steps, and the migration is complete.

+ * - Interface is synchronous : input is consumed entirely and produce 1+

+ * A ZSTD_DCtx object is required to track streaming operations.
+ * Use ZSTD_initDCtx() to initialize a context.
+ * A ZSTD_DCtx object can be re-used multiple times.
+ *
+ * First typical operation is to retrieve frame parameters, using
+ * ZSTD_getFrameParams(). It fills a ZSTD_frameParams structure which provide
+ * important information to correctly decode the frame, such as the minimum
+ * rolling buffer size to allocate to decompress data (`windowSize`), and the
+ * dictionary ID used.
+ * Note: content size is optional, it may not be present. 0 means unknown.
+ * Note that these values could be wrong, either because of data malformation,
+ * or because an attacker is spoofing deliberate false information. As a
+ * consequence, check that values remain within valid application range,
+ * especially `windowSize`, before allocation. Each application can set its own
+ * limit, depending on local restrictions. For extended interoperability, it is
+ * recommended to support at least 8 MB.
+ * Frame parameters are extracted from the beginning of the compressed frame.
+ * Data fragment must be large enough to ensure successful decoding, typically
+ * `ZSTD_frameHeaderSize_max` bytes.
+ * Result: 0: successful decoding, the `ZSTD_frameParams` structure is filled.
+ * >0: `srcSize` is too small, provide at least this many bytes.
+ * errorCode, which can be tested using ZSTD_isError().
+ *
+ * Start decompression, with ZSTD_decompressBegin() or
+ * ZSTD_decompressBegin_usingDict(). Alternatively, you can copy a prepared
+ * context, using ZSTD_copyDCtx().
+ *
+ * Then use ZSTD_nextSrcSizeToDecompress() and ZSTD_decompressContinue()
+ * alternatively.
+ * ZSTD_nextSrcSizeToDecompress() tells how many bytes to provide as 'srcSize'
+ * to ZSTD_decompressContinue().
+ * ZSTD_decompressContinue() requires this _exact_ amount of bytes, or it will
+ * fail.
+ *
+ * The result of ZSTD_decompressContinue() is the number of bytes regenerated
+ * within 'dst' (necessarily <= dstCapacity). It can be zero, which is not an
+ * error; it just means ZSTD_decompressContinue() has decoded some metadata
+ * item. It can also be an error code, which can be tested with ZSTD_isError().
+ *
+ * ZSTD_decompressContinue() needs previous data blocks during decompression, up
+ * to `windowSize`. They should preferably be located contiguously, prior to
+ * current block. Alternatively, a round buffer of sufficient size is also
+ * possible. Sufficient size is determined by frame parameters.
+ * ZSTD_decompressContinue() is very sensitive to contiguity, if 2 blocks don't
+ * follow each other, make sure that either the compressor breaks contiguity at
+ * the same place, or that previous contiguous segment is large enough to
+ * properly handle maximum back-reference.
+ *
+ * A frame is fully decoded when ZSTD_nextSrcSizeToDecompress() returns zero.
+ * Context can then be reset to start a new decompression.
+ *
+ * Note: it's possible to know if next input to present is a header or a block,
+ * using ZSTD_nextInputType(). This information is not required to properly
+ * decode a frame.
+ *
+ * == Special case: skippable frames ==
+ *
+ * Skippable frames allow integration of user-defined data into a flow of
+ * concatenated frames. Skippable frames will be ignored (skipped) by a
+ * decompressor. The format of skippable frames is as follows:
+ * a) Skippable frame ID - 4 Bytes, Little endian format, any value from
+ * 0x184D2A50 to 0x184D2A5F
+ * b) Frame Size - 4 Bytes, Little endian format, unsigned 32-bits
+ * c) Frame Content - any content (User Data) of length equal to Frame Size
+ * For skippable frames ZSTD_decompressContinue() always returns 0.
+ * For skippable frames ZSTD_getFrameParams() returns fparamsPtr->windowLog==0
+ * what means that a frame is skippable.
+ * Note: If fparamsPtr->frameContentSize==0, it is ambiguous: the frame might
+ * actually be a zstd encoded frame with no content. For purposes of
+ * decompression, it is valid in both cases to skip the frame using
+ * ZSTD_findFrameCompressedSize() to find its size in bytes.
+ * It also returns frame size as fparamsPtr->frameContentSize.

+Tutorial :
+----------
+The first step is to count all symbols. FSE_count() does this job very fast.
+Result will be saved into 'count', a table of unsigned int, which must be already allocated, and have 'maxSymbolValuePtr[0]+1' cells.
+'src' is a table of bytes of size 'srcSize'. All values within 'src' MUST be <= maxSymbolValuePtr[0]
+maxSymbolValuePtr[0] will be updated, with its real value (necessarily <= original value)
+FSE_count() will return the number of occurrence of the most frequent symbol.
+This can be used to know if there is a single symbol within 'src', and to quickly evaluate its compressibility.
+If there is an error, the function will return an ErrorCode (which can be tested using FSE_isError()).
+
+The next step is to normalize the frequencies.
+FSE_normalizeCount() will ensure that sum of frequencies is == 2 ^'tableLog'.
+It also guarantees a minimum of 1 to any Symbol with frequency >= 1.
+You can use 'tableLog'==0 to mean "use default tableLog value".
+If you are unsure of which tableLog value to use, you can ask FSE_optimalTableLog(),
+which will provide the optimal valid tableLog given sourceSize, maxSymbolValue, and a user-defined maximum (0 means "default").
+
+The result of FSE_normalizeCount() will be saved into a table,
+called 'normalizedCounter', which is a table of signed short.
+'normalizedCounter' must be already allocated, and have at least 'maxSymbolValue+1' cells.
+The return value is tableLog if everything proceeded as expected.
+It is 0 if there is a single symbol within distribution.
+If there is an error (ex: invalid tableLog value), the function will return an ErrorCode (which can be tested using FSE_isError()).
+
+'normalizedCounter' can be saved in a compact manner to a memory area using FSE_writeNCount().
+'buffer' must be already allocated.
+For guaranteed success, buffer size must be at least FSE_headerBound().
+The result of the function is the number of bytes written into 'buffer'.
+If there is an error, the function will return an ErrorCode (which can be tested using FSE_isError(); ex : buffer size too small).
+
+'normalizedCounter' can then be used to create the compression table 'CTable'.
+The space required by 'CTable' must be already allocated, using FSE_createCTable().
+You can then use FSE_buildCTable() to fill 'CTable'.
+If there is an error, both functions will return an ErrorCode (which can be tested using FSE_isError()).
+
+'CTable' can then be used to compress 'src', with FSE_compress_usingCTable().
+Similar to FSE_count(), the convention is that 'src' is assumed to be a table of char of size 'srcSize'
+The function returns the size of compressed data (without header), necessarily <= `dstCapacity`.
+If it returns '0', compressed data could not fit into 'dst'.
+If there is an error, the function will return an ErrorCode (which can be tested using FSE_isError()).

+ * that aren't pinned have the MIGRATE_PFN_MIGRATE flag set (by this function)
+ * in the corresponding src array entry. It then restores any pages that are
+ * pinned, by remapping and unlocking those pages.
+ *
+ * At this point it calls the alloc_and_copy() callback. For documentation on
+ * what is expected from that callback, see struct migrate_vma_ops comments in

+ *
+ * After the alloc_and_copy() callback, this function goes over each entry in
+ * the src array that has the MIGRATE_PFN_VALID and MIGRATE_PFN_MIGRATE flag
+ * set. If the corresponding entry in dst array has MIGRATE_PFN_VALID flag set,
+ * then the function tries to migrate struct page information from the source
+ * struct page to the destination struct page. If it fails to migrate the struct
+ * page information, then it clears the MIGRATE_PFN_MIGRATE flag in the src
+ * array.
+ *
+ * At this point all successfully migrated pages have an entry in the src
+ * array with MIGRATE_PFN_VALID and MIGRATE_PFN_MIGRATE flag set and the dst
+ * array entry with MIGRATE_PFN_VALID flag set.
+ *
+ * It then calls the finalize_and_map() callback. See comments for "struct

+ * finalize_and_map() behavior.
+ *
+ * After the finalize_and_map() callback, for successfully migrated pages, this
+ * function updates the CPU page table to point to new pages, otherwise it
+ * restores the CPU page table to point to the original source pages.
