+ * DOC: DMA fences overview
+ *
+ * DMA fences, represented by &struct dma_fence, are the kernel internal
+ * synchronization primitive for DMA operations like GPU rendering, video
+ * encoding/decoding, or displaying buffers on a screen.
+ *
+ * A fence is initialized using dma_fence_init() and completed using
+ * dma_fence_signal(). Fences are associated with a context, allocated through
+ * dma_fence_context_alloc(), and all fences on the same context are
+ * fully ordered.
+ *
+ * Since the purposes of fences is to facilitate cross-device and
+ * cross-application synchronization, there's multiple ways to use one:
+ *
+ * - Individual fences can be exposed as a &sync_file, accessed as a file
+ * descriptor from userspace, created by calling sync_file_create(). This is
+ * called explicit fencing, since userspace passes around explicit
+ * synchronization points.
+ *
+ * - Some subsystems also have their own explicit fencing primitives, like
+ * &drm_syncobj. Compared to &sync_file, a &drm_syncobj allows the underlying
+ * fence to be updated.
+ *
+ * - Then there's also implicit fencing, where the synchronization points are
+ * implicitly passed around as part of shared &dma_buf instances. Such
+ * implicit fences are stored in &struct reservation_object through the
+ * &dma_buf.resv pointer.

+ * Parade PS176), but they do not wire up the CEC pin, thus making CEC
+ * useless.
+ *
+ * Sadly there is no way for this driver to know this. What happens is
+ * that a /dev/cecX device is created that is isolated and unable to see
+ * any of the other CEC devices. Quite literally the CEC wire is cut
+ * (or in this case, never connected in the first place).
+ *
+ * The reason so few adapters support this is that this tunneling protocol
+ * was never supported by any OS. So there was no easy way of testing it,
+ * and no incentive to correctly wire up the CEC pin.
+ *
+ * Hopefully by creating this driver it will be easier for vendors to
+ * finally fix their adapters and test the CEC functionality.
+ *
+ * I keep a list of known working adapters here:
+ *
+ * https://hverkuil.home.xs4all.nl/cec-status.txt
+ *
+ * Please mail me (hverkuil@xs4all.nl) if you find an adapter that works
+ * and is not yet listed there.
+ *
+ * Note that the current implementation does not support CEC over an MST hub.
+ * As far as I can see there is no mechanism defined in the DisplayPort
+ * standard to transport CEC interrupts over an MST device. It might be
+ * possible to do this through polling, but I have not been able to get that
+ * to work.

+ * When the EDID is unset because the HPD went low, then the CEC DPCD registers

+ * short period for one reason or another, and that would cause the CEC adapter
+ * to be removed and added again, even though nothing else changed.

+/**
+ * DOC: overview
+ *
+ * Writeback connectors are used to expose hardware which can write the output
+ * from a CRTC to a memory buffer. They are used and act similarly to other
+ * types of connectors, with some important differences:
+ *
+ * * Writeback connectors don't provide a way to output visually to the user.
+ *
+ * * Writeback connectors are visible to userspace only when the client sets
+ * DRM_CLIENT_CAP_WRITEBACK_CONNECTORS.
+ *
+ * * Writeback connectors don't have EDID.
+ *
+ * A framebuffer may only be attached to a writeback connector when the
+ * connector is attached to a CRTC. The WRITEBACK_FB_ID property which sets the
+ * framebuffer applies only to a single commit (see below). A framebuffer may
+ * not be attached while the CRTC is off.
+ *
+ * Unlike with planes, when a writeback framebuffer is removed by userspace DRM
+ * makes no attempt to remove it from active use by the connector. This is
+ * because no method is provided to abort a writeback operation, and in any
+ * case making a new commit whilst a writeback is ongoing is undefined (see
+ * WRITEBACK_OUT_FENCE_PTR below). As soon as the current writeback is finished,
+ * the framebuffer will automatically no longer be in active use. As it will
+ * also have already been removed from the framebuffer list, there will be no
+ * way for any userspace application to retrieve a reference to it in the
+ * intervening period.
+ *
+ * Writeback connectors have some additional properties, which userspace
+ * can use to query and control them:
+ *
+ * "WRITEBACK_FB_ID":
+ * Write-only object property storing a DRM_MODE_OBJECT_FB: it stores the
+ * framebuffer to be written by the writeback connector. This property is
+ * similar to the FB_ID property on planes, but will always read as zero
+ * and is not preserved across commits.
+ * Userspace must set this property to an output buffer every time it
+ * wishes the buffer to get filled.
+ *
+ * "WRITEBACK_PIXEL_FORMATS":
+ * Immutable blob property to store the supported pixel formats table. The
+ * data is an array of u32 DRM_FORMAT_* fourcc values.
+ * Userspace can use this blob to find out what pixel formats are supported
+ * by the connector's writeback engine.
+ *
+ * "WRITEBACK_OUT_FENCE_PTR":
+ * Userspace can use this property to provide a pointer for the kernel to
+ * fill with a sync_file file descriptor, which will signal once the
+ * writeback is finished. The value should be the address of a 32-bit
+ * signed integer, cast to a u64.
+ * Userspace should wait for this fence to signal before making another
+ * commit affecting any of the same CRTCs, Planes or Connectors.
+ * **Failure to do so will result in undefined behaviour.**
+ * For this reason it is strongly recommended that all userspace
+ * applications making use of writeback connectors *always* retrieve an
+ * out-fence for the commit and use it appropriately.
+ * From userspace, this property will always read as zero.

+/**
+ * DOC: Overview
+ *
+ * The GPU scheduler provides entities which allow userspace to push jobs
+ * into software queues which are then scheduled on a hardware run queue.
+ * The software queues have a priority among them. The scheduler selects the entities
+ * from the run queue using a FIFO. The scheduler provides dependency handling
+ * features among jobs. The driver is supposed to provide callback functions for
+ * backend operations to the scheduler like submitting a job to hardware run queue,
+ * returning the dependencies of a job etc.
+ *
+ * The organisation of the scheduler is the following:
+ *
+ * 1. Each hw run queue has one scheduler
+ * 2. Each scheduler has multiple run queues with different priorities
+ * (e.g., HIGH_HW,HIGH_SW, KERNEL, NORMAL)
+ * 3. Each scheduler run queue has a queue of entities to schedule
+ * 4. Entities themselves maintain a queue of jobs that will be scheduled on
+ * the hardware.
+ *
+ * The jobs in a entity are always scheduled in the order that they were pushed.

+ * FAN datasheet defines the formula for RPM calculations as RPM = 15/t-high.
+ * The logic in a programmable device measures the time t-high by sampling the

+ * a counter (N) as long as the pulse has not change:
+ * RPM = 15 / (t-sample * (K + Regval)), where:
+ * Regval: is the value read from the programmable device register;
+ * - 0xff - represents tachometer fault;
+ * - 0xfe - represents tachometer minimum value , which is 4444 RPM;
+ * - 0x00 - represents tachometer maximum value , which is 300000 RPM;
+ * K: is 44 and it represents the minimum allowed samples per pulse;
+ * N: is equal K + Regval;
+ * In order to calculate RPM from the register value the following formula is
+ * used: RPM = 15 / ((Regval + K) * 11.32) * 10^(-6)), which in the
+ * default case is modified to:
+ * RPM = 15000000 * 100 / ((Regval + 44) * 1132);
+ * - for Regval 0x00, RPM will be 15000000 * 100 / (44 * 1132) = 30115;
+ * - for Regval 0xfe, RPM will be 15000000 * 100 / ((254 + 44) * 1132) = 4446;

+ *
+ * To free a range of LPIs, add a free range to the list, sort it and
+ * merge the result if the new range happens to be adjacent to an

*

+ * MT9V111 is a 1/4-Inch CMOS digital image sensor with an integrated
+ * Image Flow Processing (IFP) engine and a sensor core loosely based on
+ * MT9V011.
+ *
+ * The IFP can produce several output image formats from the sensor core
+ * output. This driver currently supports only YUYV format permutations.
+ *
+ * The driver allows manual frame rate control through s_frame_interval subdev
+ * operation or V4L2_CID_V/HBLANK controls, but it is known that the
+ * auto-exposure algorithm might modify the programmed frame rate. While the
+ * driver initially programs the sensor with auto-exposure and
+ * auto-white-balancing enabled, it is possible to disable them and more
+ * precisely control the frame rate.
+ *
+ * While it seems possible to instruct the auto-exposure control algorithm to
+ * respect a programmed frame rate when adjusting the pixel integration time,
+ * registers controlling this feature are not documented in the public
+ * available sensor manual used to develop this driver (09005aef80e90084,
+ * MT9V111_1.fm - Rev. G 1/05 EN).

+ * The compressed format consists of a cframe_hdr struct followed by the
+ * compressed frame data. The header contains the size of that data.
+ * Each Y, Cb and Cr plane is compressed separately. If the compressed
+ * size of each plane becomes larger than the uncompressed size, then
+ * that plane is stored uncompressed and the corresponding bit is set
+ * in the flags field of the header.
+ *
+ * Each compressed plane consists of macroblocks and each macroblock
+ * is run-length-encoded. Each macroblock starts with a 16 bit value.
+ * Bit 15 indicates if this is a P-coded macroblock (1) or not (0).
+ * P-coded macroblocks contain a delta against the previous frame.
+ *
+ * Bits 1-12 contain a number. If non-zero, then this same macroblock
+ * repeats that number of times. This results in a high degree of
+ * compression for generated images like colorbars.
+ *
+ * Following this macroblock header the MB coefficients are run-length
+ * encoded: the top 12 bits contain the coefficient, the bottom 4 bits
+ * tell how many times this coefficient occurs. The value 0xf indicates
+ * that the remainder of the macroblock should be filled with zeroes.
+ *
+ * All 16 and 32 bit values are stored in big-endian (network) order.
+ *
+ * Each cframe_hdr starts with an 8 byte magic header that is
+ * guaranteed not to occur in the compressed frame data. This header
+ * can be used to sync to the next frame.
+ *
+ * This codec uses the Fast Walsh Hadamard Transform. Tom aan de Wiel

+ * with this driver. His project report can be found here:
+ *

+ *
+ * General Description:
+ *
+ * The USB Device uses three Endpoints:
+ *
+ * CONTROL Endpoint: Is used the setup the device (start, stop,
+ * info, configure).
+ *
+ * IN Endpoint: The device sends CAN Frame Messages and Device
+ * Information using the IN endpoint.
+ *
+ * OUT Endpoint: The driver sends configuration requests, and CAN
+ * Frames on the out endpoint.
+ *
+ * Error Handling:
+ *
+ * If error reporting is turned on the device encodes error into CAN
+ * error frames (see uapi/linux/can/error.h) and sends it using the
+ * IN Endpoint. The driver updates statistics and forward it.

+ * OUT Endpoint: single message of type ucan_message_out_t is

+ * RTL8366RB - Probably reads out "RTL8366 revision B", has a quite
+ * different register layout from the other two
+ * RTL8366S - Is this "RTL8366 super"?
+ * RTL8367 - Has an OpenWRT driver as well

+ * Some IDT switches incorrectly flag an ACS Source Validation error on

+ *
+ * Item #36 - Downstream port applies ACS Source Validation to Completions
+ * Section 6.12.1.1 of the PCI Express Base Specification 3.1 states that
+ * completions are never affected by ACS Source Validation. However,
+ * completions received by a downstream port of the PCIe switch from a
+ * device that has not yet captured a PCIe bus number are incorrectly
+ * dropped by ACS Source Validation by the switch downstream port.
+ *
+ * The workaround suggested by IDT is to issue a config write to the
+ * downstream device before issuing the first config read. This allows the
+ * downstream device to capture its bus and device numbers (see PCIe r4.0,
+ * sec 2.2.9), thus avoiding the ACS error on the completion.
+ *
+ * However, we don't know when the device is ready to accept the config
+ * write, so we do config reads until we receive a non-Config Request Retry
+ * Status, then do the config write.
+ *
+ * To avoid hitting the erratum when doing the config reads, we disable ACS
+ * SV around this process.

+ *
+ * All of the kthreads used for idle injection are created at init time.
+ *
+ * Next, the users of the the idle injection framework provide a cpumask via

+ * this cpumask.
+ *
+ * The idle + run duration is specified via separate helpers and that allows
+ * idle injection to be started.
+ *
+ * The idle injection kthreads will call play_idle() with the idle duration
+ * specified as per the above.
+ *
+ * After all of them have been woken up, a timer is set to start the next idle
+ * injection cycle.
+ *
+ * The timer interrupt handler will wake up the idle injection kthreads for
+ * all of the CPUs in the cpumask provided by the user.
+ *
+ * Idle injection is stopped synchronously and no leftover idle injection
+ * kthread activity after its completion is guaranteed.
+ *
+ * It is up to the user of this framework to provide a lock for higher-level

-/* Notes:
- *
- * Most of the work is done in the chip specific module, 53c700.o
- *
- * TODO List:
- *
- * 1. Extract the SCSI ID from the voyager CMOS table (necessary to
- * support multi-host environments.
- *
- * */
-
-
-/* CHANGELOG
- *
- * Version 2.2
- *
- * Added mca_set_adapter_name().
- *
- * Version 2.1
- *
- * Modularise the driver into a Board piece (this file) and a chip
- * piece 53c700.[ch] and 53c700.scr, added module options. You can
- * now specify the scsi id by the parameters
- *
- * NCR_D700=slot:<n> [siop:<n>] id:<n> ....
- *
- * They need to be comma separated if compiled into the kernel
- *
- * Version 2.0
- *
- * Initial implementation of TCQ (Tag Command Queueing). TCQ is full
- * featured and uses the clock algorithm to keep track of outstanding
- * tags and guard against individual tag starvation. Also fixed a bug
- * in all of the 1.x versions where the D700_data_residue() function
- * was returning results off by 32 bytes (and thus causing the same 32
- * bytes to be written twice corrupting the data block). It turns out
- * the 53c700 only has a 6 bit DBC and DFIFO registers not 7 bit ones
- * like the 53c710 (The 710 is the only data manual still available,
- * which I'd been using to program the 700).
- *
- * Version 1.2
- *
- * Much improved message handling engine
- *
- * Version 1.1
- *
- * Add code to handle selection reasonably correctly. By the time we
- * get the selection interrupt, we've already responded, but drop off the
- * bus and hope the selector will go away.
- *
- * Version 1.0:
- *
- * Initial release. Fully functional except for procfs and tag
- * command queueing. Has only been tested on cards with 53c700-66
- * chips and only single ended. Features are
- *
- * 1. Synchronous data transfers to offset 8 (limit of 700-66) and
- * 100ns (10MHz) limit of SCSI-2
- *
- * 2. Disconnection and reselection
- *
- * Testing:
- *
- * I've only really tested this with the 700-66 chip, but have done
- * soak tests in multi-device environments to verify that
- * disconnections and reselections are being processed correctly.
- * */
