-************************************************************
-* For the very latest on DRI development, please see:      *
-*     http://dri.freedesktop.org/                          *
-************************************************************
-
-The Direct Rendering Manager (drm) is a device-independent kernel-level
-device driver that provides support for the XFree86 Direct Rendering
-Infrastructure (DRI).
-
-The DRM supports the Direct Rendering Infrastructure (DRI) in four major
-ways:
-
-    1. The DRM provides synchronized access to the graphics hardware via
-       the use of an optimized two-tiered lock.
-
-    2. The DRM enforces the DRI security policy for access to the graphics
-       hardware by only allowing authenticated X11 clients access to
-       restricted regions of memory.
-
-    3. The DRM provides a generic DMA engine, complete with multiple
-       queues and the ability to detect the need for an OpenGL context
-       switch.
-
-    4. The DRM is extensible via the use of small device-specific modules
-       that rely extensively on the API exported by the DRM module.
-
-
-Documentation on the DRI is available from:
-    http://dri.freedesktop.org/wiki/Documentation
-    http://sourceforge.net/project/showfiles.php?group_id=387
-    http://dri.sourceforge.net/doc/
-

-    Infrastructure

+ * Fence helper functions to deal with KFD memory eviction.

+ *  evicted unless all the user queues for that process are evicted.
+ *
+ * All the BOs in a process share an eviction fence. When process X wants
+ * to map VRAM memory but TTM can't find enough space, TTM will attempt to
+ * evict BOs from its LRU list. TTM checks if the BO is valuable to evict
+ * by calling ttm_device_funcs->eviction_valuable().
+ *
+ * ttm_device_funcs->eviction_valuable() - will return false if the BO belongs
+ *  to process X. Otherwise, it will return true to indicate BO can be
+ *  evicted by TTM.
+ *
+ * If ttm_device_funcs->eviction_valuable returns true, then TTM will continue
+ * the evcition process for that BO by calling ttm_bo_evict --> amdgpu_bo_move
+ * --> amdgpu_copy_buffer(). This sets up job in GPU scheduler.
+ *
+ * GPU Scheduler (amd_sched_main) - sets up a cb (fence_add_callback) to
+ *  nofity when the BO is free to move. fence_add_callback --> enable_signaling
+ *  --> amdgpu_amdkfd_fence.enable_signaling
+ *
+ * amdgpu_amdkfd_fence.enable_signaling - Start a work item that will quiesce
+ * user queues and signal fence. The work item will also start another delayed

+ *
+ *  For each bit that is ON from above:

+/* EEPROM memory addresses are 19-bits long, which can
+ * be partitioned into 3, 8, 8 bits, for a total of 19.
+ * The upper 3 bits are sent as part of the 7-bit
+ * "Device Type Identifier"--an I2C concept, which for EEPROM devices
+ * is hard-coded as 1010b, indicating that it is an EEPROM
+ * device--this is the wire format, followed by the upper
+ * 3 bits of the 19-bit address, followed by the direction,
+ * followed by two bytes holding the rest of the 16-bits of
+ * the EEPROM memory address. The format on the wire for EEPROM
+ * devices is: 1010XYZD, A15:A8, A7:A0,
+ * Where D is the direction and sequenced out by the hardware.
+ * Bits XYZ are memory address bits 18, 17 and 16.
+ * These bits are compared to how pins 1-3 of the part are connected,
+ * depending on the size of the part, more on that later.
+ *
+ * Note that of this wire format, a client is in control
+ * of, and needs to specify only XYZ, A15:A8, A7:0, bits,
+ * which is exactly the EEPROM memory address, or offset,
+ * in order to address up to 8 EEPROM devices on the I2C bus.
+ *
+ * For instance, a 2-Mbit I2C EEPROM part, addresses all its bytes,
+ * using an 18-bit address, bit 17 to 0 and thus would use all but one bit of
+ * the 19 bits previously mentioned. The designer would then not connect
+ * pins 1 and 2, and pin 3 usually named "A_2" or "E2", would be connected to
+ * either Vcc or GND. This would allow for up to two 2-Mbit parts on
+ * the same bus, where one would be addressable with bit 18 as 1, and
+ * the other with bit 18 of the address as 0.
+ *
+ * For a 2-Mbit part, bit 18 is usually known as the "Chip Enable" or
+ * "Hardware Address Bit". This bit is compared to the load on pin 3
+ * of the device, described above, and if there is a match, then this
+ * device responds to the command. This way, you can connect two
+ * 2-Mbit EEPROM devices on the same bus, but see one contiguous
+ * memory from 0 to 7FFFFh, where address 0 to 3FFFF is in the device
+ * whose pin 3 is connected to GND, and address 40000 to 7FFFFh is in
+ * the 2nd device, whose pin 3 is connected to Vcc.
+ *
+ * This addressing you encode in the 32-bit "eeprom_addr" below,
+ * namely the 19-bits "XYZ,A15:A0", as a single 19-bit address. For
+ * instance, eeprom_addr = 0x6DA01, is 110_1101_1010_0000_0001, where
+ * XYZ=110b, and A15:A0=DA01h. The XYZ bits become part of the device
+ * address, and the rest of the address bits are sent as the memory
+ * address bytes.
+ *
+ * That is, for an I2C EEPROM driver everything is controlled by
+ * the "eeprom_addr".
+ *
+ * See also top of amdgpu_ras_eeprom.c.
+ *
+ * P.S. If you need to write, lock and read the Identification Page,
+ * (M24M02-DR device only, which we do not use), change the "7" to
+ * "0xF" in the macro below, and let the client set bit 20 to 1 in
+ * "eeprom_addr", and set A10 to 0 to write into it, and A10 and A1 to
+ * 1 to lock it permanently.

+ * GART
+ * The GART (Graphics Aperture Remapping Table) is an aperture
+ * in the GPU's address space.  System pages can be mapped into
+ * the aperture and look like contiguous pages from the GPU's
+ * perspective.  A page table maps the pages in the aperture
+ * to the actual backing pages in system memory.
+ *
+ * Radeon GPUs support both an internal GART, as described above,
+ * and AGP.  AGP works similarly, but the GART table is configured
+ * and maintained by the northbridge rather than the driver.
+ * Radeon hw has a separate AGP aperture that is programmed to
+ * point to the AGP aperture provided by the northbridge and the
+ * requests are passed through to the northbridge aperture.
+ * Both AGP and internal GART can be used at the same time, however
+ * that is not currently supported by the driver.
+ *
+ * This file handles the common internal GART management.

+ * to enable the KFD scheduler is made, the reference count is decremented.
+ * When the reference count reaches zero, a delayed work is scheduled to
+ * enforce isolation after a delay of GFX_SLICE_PERIOD.
+ *
+ * When a request to disable the KFD scheduler is made, the function first
+ * checks if the reference count is zero. If it is, it cancels the delayed work
+ * for enforcing isolation and checks if the KFD scheduler is active. If the
+ * KFD scheduler is active, it sends a request to stop the KFD scheduler and
+ * sets the KFD scheduler state to inactive. Then, it increments the reference
+ * count.
+ *
+ * The function is synchronized using the kfd_sch_mutex to ensure that the KFD
+ * scheduler state and reference count are updated atomically.

+ * MES lock can be taken in MMU notifiers.
+ *
+ * A bit more detail about why to set no-FS reclaim with MES lock:
+ *
+ * The purpose of the MMU notifier is to stop GPU access to memory so
+ * that the Linux VM subsystem can move pages around safely. This is
+ * done by preempting user mode queues for the affected process. When
+ * MES is used, MES lock needs to be taken to preempt the queues.
+ *
+ * The MMU notifier callback entry point in the driver is
+ * amdgpu_mn_invalidate_range_start_hsa. The relevant call chain from
+ * there is:
+ * amdgpu_amdkfd_evict_userptr -> kgd2kfd_quiesce_mm ->
+ * kfd_process_evict_queues -> pdd->dev->dqm->ops.evict_process_queues
+ *
+ * The last part of the chain is a function pointer where we take the
+ * MES lock.
+ *
+ * The problem with taking locks in the MMU notifier is, that MMU
+ * notifiers can be called in reclaim-FS context. That's where the
+ * kernel frees up pages to make room for new page allocations under
+ * memory pressure. While we are running in reclaim-FS context, we must
+ * not trigger another memory reclaim operation because that would
+ * recursively reenter the reclaim code and cause a deadlock. The
+ * memalloc_nofs_save/restore calls guarantee that.
+ *
+ * In addition we also need to avoid lock dependencies on other locks taken
+ * under the MES lock, for example reservation locks. Here is a possible
+ * scenario of a deadlock:
+ * Thread A: takes and holds reservation lock | triggers reclaim-FS |
+ * MMU notifier | blocks trying to take MES lock
+ * Thread B: takes and holds MES lock | blocks trying to take reservation lock
+ *
+ * In this scenario Thread B gets involved in a deadlock even without
+ * triggering a reclaim-FS operation itself.
+ * To fix this and break the lock dependency chain you'd need to either:
+ * 1. protect reservation locks with memalloc_nofs_save/restore, or
+ * 2. avoid taking reservation locks under the MES lock.
+ *
+ * Reservation locks are taken all over the kernel in different subsystems, we
+ * have no control over them and their lock dependencies.So the only workable
+ * solution is to avoid taking other locks under the MES lock.
+ * As a result, make sure no reclaim-FS happens while holding this lock anywhere
+ * to prevent deadlocks when an MMU notifier runs in reclaim-FS context.

+ * DOC: AMDGPU TA debugfs interfaces
+ *
+ * Three debugfs interfaces can be opened by a program to
+ * load/invoke/unload TA,

+ * - /sys/kernel/debug/dri/<N>/ta_if/ta_invoke
+ * - /sys/kernel/debug/dri/<N>/ta_if/ta_unload
+ *
+ * How to use the interfaces in a program?
+ *
+ * A program needs to provide transmit buffer to the interfaces
+ * and will receive buffer from the interfaces below,
+ *
+ * - For TA load debugfs interface:
+ *   Transmit buffer:
+ *    - TA type (4bytes)
+ *    - TA bin length (4bytes)
+ *    - TA bin
+ *   Receive buffer:
+ *    - TA ID (4bytes)
+ *
+ * - For TA invoke debugfs interface:
+ *   Transmit buffer:
+ *    - TA type (4bytes)
+ *    - TA ID (4bytes)
+ *    - TA CMD ID (4bytes)
+ *    - TA shard buf length
+ *      (4bytes, value not beyond TA shared memory size)
+ *    - TA shared buf
+ *   Receive buffer:
+ *    - TA shared buf
+ *
+ * - For TA unload debugfs interface:
+ *   Transmit buffer:
+ *    - TA type (4bytes)

+/**
+ * DOC: AMDGPU RAS debugfs control interface
+ *
+ * The control interface accepts struct ras_debug_if which has two members.
+ *
+ * First member: ras_debug_if::head or ras_debug_if::inject.
+ *
+ * head is used to indicate which IP block will be under control.
+ *
+ * head has four members, they are block, type, sub_block_index, name.
+ * block: which IP will be under control.
+ * type: what kind of error will be enabled/disabled/injected.
+ * sub_block_index: some IPs have subcomponets. say, GFX, sDMA.
+ * name: the name of IP.
+ *
+ * inject has three more members than head, they are address, value and mask.
+ * As their names indicate, inject operation will write the
+ * value to the address.
+ *
+ * The second member: struct ras_debug_if::op.
+ * It has three kinds of operations.
+ *
+ * - 0: disable RAS on the block. Take ::head as its data.
+ * - 1: enable RAS on the block. Take ::head as its data.
+ * - 2: inject errors on the block. Take ::inject as its data.
+ *
+ * How to use the interface?
+ *
+ * In a program
+ *
+ * Copy the struct ras_debug_if in your code and initialize it.
+ * Write the struct to the control interface.
+ *
+ * From shell
+ *
+ * .. code-block:: bash
+ *
+ *	echo "disable <block>" > /sys/kernel/debug/dri/<N>/ras/ras_ctrl
+ *	echo "enable  <block> <error>" > /sys/kernel/debug/dri/<N>/ras/ras_ctrl
+ *	echo "inject  <block> <error> <sub-block> <address> <value> <mask>" > /sys/kernel/debug/dri/<N>/ras/ras_ctrl
+ *
+ * Where N, is the card which you want to affect.
+ *
+ * "disable" requires only the block.
+ * "enable" requires the block and error type.
+ * "inject" requires the block, error type, address, and value.
+ *
+ * The block is one of: umc, sdma, gfx, etc.
+ *	see ras_block_string[] for details
+ *
+ * The error type is one of: ue, ce and poison where,
+ *	ue is multi-uncorrectable
+ *	ce is single-correctable
+ *	poison is poison
+ *
+ * The sub-block is a the sub-block index, pass 0 if there is no sub-block.
+ * The address and value are hexadecimal numbers, leading 0x is optional.
+ * The mask means instance mask, is optional, default value is 0x1.
+ *
+ * For instance,
+ *
+ * .. code-block:: bash
+ *
+ *	echo inject umc ue 0x0 0x0 0x0 > /sys/kernel/debug/dri/0/ras/ras_ctrl
+ *	echo inject umc ce 0 0 0 3 > /sys/kernel/debug/dri/0/ras/ras_ctrl
+ *	echo disable umc > /sys/kernel/debug/dri/0/ras/ras_ctrl
+ *
+ * How to check the result of the operation?
+ *
+ * To check disable/enable, see "ras" features at,
+ * /sys/class/drm/card[0/1/2...]/device/ras/features
+ *
+ * To check inject, see the corresponding error count at,
+ * /sys/class/drm/card[0/1/2...]/device/ras/[gfx|sdma|umc|...]_err_count
+ *
+ * .. note::
+ *	Operations are only allowed on blocks which are supported.
+ *	Check the "ras" mask at /sys/module/amdgpu/parameters/ras_mask
+ *	to see which blocks support RAS on a particular asic.

+ * DOC: AMDGPU RAS Reboot Behavior for Unrecoverable Errors
+ *
+ * Normally when there is an uncorrectable error, the driver will reset
+ * the GPU to recover.  However, in the event of an unrecoverable error,
+ * the driver provides an interface to reboot the system automatically
+ * in that event.
+ *
+ * The following file in debugfs provides that interface:
+ * /sys/kernel/debug/dri/[0/1/2...]/ras/auto_reboot
+ *
+ * Usage:
+ *
+ * .. code-block:: bash
+ *
+ *	echo true > .../ras/auto_reboot

+/**
+ * DOC: amdgpu_vkms
+ *
+ * The amdgpu vkms interface provides a virtual KMS interface for several use
+ * cases: devices without display hardware, platforms where the actual display
+ * hardware is not useful (e.g., servers), SR-IOV virtual functions, device
+ * emulation/simulation, and device bring up prior to display hardware being
+ * usable. We previously emulated a legacy KMS interface, but there was a desire
+ * to move to the atomic KMS interface. The vkms driver did everything we
+ * needed, but we wanted KMS support natively in the driver without buffer
+ * sharing and the ability to support an instance of VKMS per device. We first
+ * looked at splitting vkms into a stub driver and a helper module that other
+ * drivers could use to implement a virtual display, but this strategy ended up
+ * being messy due to driver specific callbacks needed for buffer management.
+ * Ultimately, it proved easier to import the vkms code as it mostly used core
+ * drm helpers anyway.

+/**
+ * DOC: GPUVM
+ *
+ * GPUVM is the MMU functionality provided on the GPU.
+ * GPUVM is similar to the legacy GART on older asics, however
+ * rather than there being a single global GART table
+ * for the entire GPU, there can be multiple GPUVM page tables active
+ * at any given time.  The GPUVM page tables can contain a mix
+ * VRAM pages and system pages (both memory and MMIO) and system pages
+ * can be mapped as snooped (cached system pages) or unsnooped
+ * (uncached system pages).
+ *
+ * Each active GPUVM has an ID associated with it and there is a page table
+ * linked with each VMID.  When executing a command buffer,
+ * the kernel tells the engine what VMID to use for that command
+ * buffer.  VMIDs are allocated dynamically as commands are submitted.
+ * The userspace drivers maintain their own address space and the kernel
+ * sets up their pages tables accordingly when they submit their
+ * command buffers and a VMID is assigned.
+ * The hardware supports up to 16 active GPUVMs at any given time.
+ *
+ * Each GPUVM is represented by a 1-2 or 1-5 level page table, depending
+ * on the ASIC family.  GPUVM supports RWX attributes on each page as well
+ * as other features such as encryption and caching attributes.
+ *
+ * VMID 0 is special.  It is the GPUVM used for the kernel driver.  In
+ * addition to an aperture managed by a page table, VMID 0 also has
+ * several other apertures.  There is an aperture for direct access to VRAM
+ * and there is a legacy AGP aperture which just forwards accesses directly
+ * to the matching system physical addresses (or IOVAs when an IOMMU is
+ * present).  These apertures provide direct access to these memories without
+ * incurring the overhead of a page table.  VMID 0 is used by the kernel
+ * driver for tasks like memory management.

+ * DOC: AMDGPU XGMI Support
+ *
+ * XGMI is a high speed interconnect that joins multiple GPU cards
+ * into a homogeneous memory space that is organized by a collective
+ * hive ID and individual node IDs, both of which are 64-bit numbers.
+ *
+ * The file xgmi_device_id contains the unique per GPU device ID and
+ * is stored in the /sys/class/drm/card${cardno}/device/ directory.
+ *
+ * Inside the device directory a sub-directory 'xgmi_hive_info' is
+ * created which contains the hive ID and the list of nodes.
+ *
+ * The hive ID is stored in:
+ *   /sys/class/drm/card${cardno}/device/xgmi_hive_info/xgmi_hive_id
+ *
+ * The node information is stored in numbered directories:
+ *   /sys/class/drm/card${cardno}/device/xgmi_hive_info/node${nodeno}/xgmi_device_id
+ *
+ * Each device has their own xgmi_hive_info direction with a mirror
+ * set of node sub-directories.
+ *
+ * The XGMI memory space is built by contiguously adding the power of
+ * two padded VRAM space from each node to each other.

+//   Waves are launched in "CU" mode, and the workgroup shares 64KB of LDS (half of the WGP's LDS)
+//      It takes 2 workgroups to use all of LDS: one on each CU of the WGP
+//   Each wave clears SGPRs 0 - 107
+//   Each wave clears VGPRs 0 - 63
+//   The first wave of the workgroup clears its 64KB of LDS
+//   The shader starts with "S_BARRIER" to ensure SPI has launched all waves of the workgroup
+//       before any wave in the workgroup could end.  Without this, it is possible not all SGPRs get cleared.

+// GFX10.3 : Clear SGPRs, VGPRs and LDS
+//   Launch 32 waves per CU (16 per SIMD) as a workgroup (threadgroup) to fill every wave slot
+//   Waves are "wave32" and have 64 VGPRs each, which uses all 1024 VGPRs per SIMD
+//   Waves are launched in "CU" mode, and the workgroup shares 64KB of LDS (half of the WGP's LDS)
+//      It takes 2 workgroups to use all of LDS: one on each CU of the WGP
+//   Each wave clears SGPRs 0 - 107
+//   Each wave clears VGPRs 0 - 63
+//   The first wave of the workgroup clears its 64KB of LDS
+//   The shader starts with "S_BARRIER" to ensure SPI has launched all waves of the workgroup
+//       before any wave in the workgroup could end.  Without this, it is possible not all SGPRs get cleared.
