Pull drm updates from Dave Airlie:
 "The biggest highlight is that the accel subsystem framework is merged.
  Hopefully for 6.3 we will be able to line up a driver to use it.

  In drivers land, i915 enables DG2 support by default now, and nouveau
  has a big stability refactoring and initial ampere support, AMD
  includes new hw IP support and should build on ARM again. There is
  also an ofdrm driver to take over offb on platforms it's used.

  Stuff outside my tree, the dma-buf patches hit a few places, the vc4
  firmware changes also do, and i915 has some interactions with MEI for

Introduction
============
The Linux compute accelerators subsystem is designed to expose compute
accelerators in a common way to user-space and provide a common set of
functionality.
These devices can be either stand-alone ASICs or IP blocks inside an SoC/GPU.
Although these devices are typically designed to accelerate
Machine-Learning (ML) and/or Deep-Learning (DL) computations, the accel layer
is not limited to handling these types of accelerators.
Typically, a compute accelerator will belong to one of the following
categories:
- Edge AI - doing inference at an edge device. It can be an embedded ASIC/FPGA,
or an IP inside a SoC (e.g. laptop web camera). These devices
are typically configured using registers and can work with or without DMA.
- Inference data-center - single/multi user devices in a large server. This
type of device can be stand-alone or an IP inside a SoC or a GPU. It will
have on-board DRAM (to hold the DL topology), DMA engines and
command submission queues (either kernel or user-space queues).
It might also have an MMU to manage multiple users and might also enable
virtualization (SR-IOV) to support multiple VMs on the same device. In
addition, these devices will usually have some tools, such as profiler and
debugger.
- Training data-center - Similar to Inference data-center cards, but typically
have more computational power and memory b/w (e.g. HBM) and will likely have
a method of scaling-up/out, i.e. connecting to other training cards inside
the server or in other servers, respectively.
All these devices typically have different runtime user-space software stacks,
that are tailored-made to their h/w. In addition, they will also probably
include a compiler to generate programs to their custom-made computational
engines. Typically, the common layer in user-space will be the DL frameworks,
such as PyTorch and TensorFlow.
Sharing code with DRM
=====================
Because this type of devices can be an IP inside GPUs or have similar
characteristics as those of GPUs, the accel subsystem will use the
DRM subsystem's code and functionality. i.e. the accel core code will
be part of the DRM subsystem and an accel device will be a new type of DRM
device.
This will allow us to leverage the extensive DRM code-base and
collaborate with DRM developers that have experience with this type of
devices. In addition, new features that will be added for the accelerator
drivers can be of use to GPU drivers as well.
Differentiation from GPUs
=========================
Because we want to prevent the extensive user-space graphic software stack
from trying to use an accelerator as a GPU, the compute accelerators will be
differentiated from GPUs by using a new major number and new device char files.
Furthermore, the drivers will be located in a separate place in the kernel
tree - drivers/accel/.
The accelerator devices will be exposed to the user space with the dedicated
261 major number and will have the following convention:
- device char files - /dev/accel/accel*
- sysfs - /sys/class/accel/accel*/
- debugfs - /sys/kernel/debug/accel/accel*/
Getting Started
===============
First, read the DRM documentation at Documentation/gpu/index.rst.
Not only it will explain how to write a new DRM driver but it will also
contain all the information on how to contribute, the Code Of Conduct and
what is the coding style/documentation. All of that is the same for the
accel subsystem.
Second, make sure the kernel is configured with CONFIG_DRM_ACCEL.
To expose your device as an accelerator, two changes are needed to
be done in your driver (as opposed to a standard DRM driver):
- Add the DRIVER_COMPUTE_ACCEL feature flag in your drm_driver's
driver_features field. It is important to note that this driver feature is
mutually exclusive with DRIVER_RENDER and DRIVER_MODESET. Devices that want
to expose both graphics and compute device char files should be handled by
two drivers that are connected using the auxiliary bus framework.
- Change the open callback in your driver fops structure to accel_open().
Alternatively, your driver can use DEFINE_DRM_ACCEL_FOPS macro to easily
set the correct function operations pointers structure.

GART
Graphics Address Remapping Table. This is the name we use for the GPUVM
page table used by the GPU kernel driver. It remaps system resources
(memory or MMIO space) into the GPU's address space so the GPU can access
them. The name GART harkens back to the days of AGP when the platform
provided an MMU that the GPU could use to get a contiguous view of
scattered pages for DMA. The MMU has since moved on to the GPU, but the
name stuck.
GC
Graphics and Compute
GMC
Graphic Memory Controller
GPUVM
GPU Virtual Memory. This is the GPU's MMU. The GPU supports multiple
virtual address spaces that can be in flight at any given time. These
allow the GPU to remap VRAM and system resources into GPU virtual address
spaces for use by the GPU kernel driver and applications using the GPU.
These provide memory protection for different applications using the GPU.
GTT
Graphics Translation Tables. This is a memory pool managed through TTM
which provides access to system resources (memory or MMIO space) for
use by the GPU. These addresses can be mapped into the "GART" GPUVM page
table for use by the kernel driver or into per process GPUVM page tables
for application usage.

vmwgfx: Replace hashtable with Linux' implementation
----------------------------------------------------
The vmwgfx driver uses its own hashtable implementation. Replace the
code with Linux' implementation and update the callers. It's mostly a
refactoring task, but the interfaces are different.

Framework for device drivers of compute acceleration devices, such
as, but not limited to, Machine-Learning and Deep-Learning
acceleration devices.
If you say Y here, you need to select the module that's right for
your acceleration device from the list below.
This framework is integrated with the DRM subsystem as compute
accelerators and GPUs share a lot in common and can use almost the
same infrastructure code.
Having said that, acceleration devices will have a different
major number than GPUs, and will be exposed to user-space using
different device files, called accel/accel* (in /dev, sysfs
and debugfs).

* DOC: locking convention
*
* In order to avoid deadlock situations between dma-buf exports and importers,

*
* Convention for importers
*
* 1. Importers must hold the dma-buf reservation lock when calling these
* functions:
*
* - dma_buf_pin()
* - dma_buf_unpin()
* - dma_buf_map_attachment()
* - dma_buf_unmap_attachment()
* - dma_buf_vmap()
* - dma_buf_vunmap()
*
* 2. Importers must not hold the dma-buf reservation lock when calling these
* functions:
*
* - dma_buf_attach()
* - dma_buf_dynamic_attach()
* - dma_buf_detach()
* - dma_buf_export(
* - dma_buf_fd()
* - dma_buf_get()

* - dma_buf_map_attachment_unlocked()
* - dma_buf_unmap_attachment_unlocked()
* - dma_buf_vmap_unlocked()
* - dma_buf_vunmap_unlocked()
*
* Convention for exporters
*
* 1. These &dma_buf_ops callbacks are invoked with unlocked dma-buf
* reservation and exporter can take the lock:
*
* - &dma_buf_ops.attach()
* - &dma_buf_ops.detach()
* - &dma_buf_ops.release()
* - &dma_buf_ops.begin_cpu_access()
* - &dma_buf_ops.end_cpu_access()
