Pull drm updates from Dave Airlie:
"As part of building up nova-core/nova-drm pieces we've brought in some
rust abstractions through this tree, aux bus being the main one, with
devres changes also in the driver-core tree. Along with the drm core
abstractions and enough nova-core/nova-drm to use them. This is still
all stub work under construction, to build the nova driver upstream.
The other big NVIDIA related one is nouveau adds support for
Hopper/Blackwell GPUs, this required a new GSP firmware update to
570.144, and a bunch of rework in order to support multiple fw
interfaces.
There is also the introduction of an asahi uapi header file as a
precursor to getting the real driver in later, but to unblock
userspace mesa packages while the driver is trapped behind rust
enablement.
Otherwise it's the usual mixture of stuff all over, amdgpu, i915/xe,

Documentation/userspace-api/media/glossary.rst:170: WARNING: duplicate term description of SPI, other instance in gpu/amdgpu/amdgpu-glossary
That's because SPI of amdgpu (Shader Processor Input) shares the same
global glossary term as SPI of media subsystem (which is Serial
Peripheral Interface Bus). Disambiguate the former from the latter to
fix the warning.
Note that adding context qualifiers in the term is strictly necessary
in order to make Sphinx happy.

Add the register!() macro, which defines a given register's layout and
provide bit-field accessors with a way to convert them to a given type.
This macro will allow us to make clear definitions of the registers and
manipulate their fields safely.
The long-term goal is to eventually move it to the kernel crate so it
can be used by other drivers as well, but it was agreed to first land it
into nova-core and make it mature there.
To illustrate its usage, use it to define the layout for the Boot0
(renamed to NV_PMC_BOOT_0 to match OpenRM's naming scheme) and take
advantage of its accessors.

This adds the UAPI for the Asahi driver targeting the GPU in the Apple
M1 and M2 series systems on chip. The UAPI design is based on other
modern Vulkan-capable drivers, including Xe and Panthor. Memory
management is based on explicit VM management. Synchronization is
exclusively explicit sync.
This UAPI is validated against our open source Mesa stack, which is
fully conformant to the OpenGL 4.6, OpenGL ES 3.2, OpenCL 3.0, and
Vulkan 1.4 standards. The Vulkan driver supports sparse, exercising the
VM_BIND mechanism.
This patch adds the standalone UAPI header. It is implemented by an open
source DRM driver written in Rust. We fully intend to upstream this
driver when possible. However, as a production graphics driver, it
depends on a significant number of Rust abstractions that will take a
long time to upstream. In the mean time, our userspace is upstream in
Mesa but is not allowed to probe with upstream Mesa as the UAPI is not
yet reviewed and merged in the upstream kernel. Although we ship a
patched Mesa in Fedora Asahi Remix, any containers shipping upstream
Mesa builds are broken for our users, including upstream Flatpak and
Waydroid runtimes. Additionally, it forces us to maintain forks of Mesa
and virglrenderer, which complicates bisects.
The intention in sending out this patch is for this UAPI to be
thoroughly reviewed. Once we as the DRM community are satisfied with the
UAPI, this header lands signifying that the UAPI is stable and must only
be evolved in backwards-compatible ways; it will be the UAPI implemented
in the DRM driver that eventually lands upstream. That promise lets us
enable upstream Mesa, solving all these issues while the upstream Rust
abstractions are developed.
https://github.com/alyssarosenzweig/linux/commits/agx-uapi-v7 contains
the DRM driver implementing this proposed UAPI.
https://gitlab.freedesktop.org/mesa/mesa/-/merge_requests/33984 contains
the Mesa patches to implement this proposed UAPI.
That Linux and Mesa branch together give a complete graphics/compute
stack on top of this UAPI.

Pipes and Queues are two common vocabulary that pervades discussions
around amdgpu core features. The definition and explanation of those
components are spread around multiple places in the code, mailing list,
and Gitlab, which sometimes leads to the wrong interpretation of these
concepts. This commit attempts to centralize the definition and
explanation of Pipe and Queue from amdgpu perspective in a kernel doc.
Most of the information in this doc was derived from:

Due to wrong `.. kernel-doc` directive in Documentation/gpu/rfc/gpusvm.rst
the documentation was actually not parsing anything from
drivers/gpu/drm/drm_gpusvm.c. This fixes the kernel-doc include and all
warnings/errors created when doing so.

We have enabled PROVE_LOCKING (which enables LOCKDEP) in drm-ci.
This will output warnings when kernel locking errors are encountered
and will continue executing tests. To detect if lockdep has been
triggered, check the debug_locks value in /proc/lockdep_stats after
the tests have run. When debug_locks is 0, it indicates that lockdep
has detected issues and turned itself off. Check this value, and if
lockdep is detected, exit with an error and configure it as a warning
in GitLab CI.
GitLab CI ignores exit codes other than 1 by default. Pass the correct
exit code with variable FF_USE_NEW_BASH_EVAL_STRATEGY set to true or
exit on failure.
Also update the documentation.

Add the initial documentation of the Nova project.
The initial project documentation consists out of a brief introduction
of the project, as well as project guidelines both general and nova-core
specific and a task list for nova-core specifically.
The task list is divided into tasks for general Rust infrastructure
required by the project, tasks regarding GSP enablement and firmware
abstraction, general GPU driver tasks as well as tasks related to
external API design and test infrastructure.

There can be multiple cases of handling the GSP RPC messages, which are
the reply of GSP RPC commands according to the requirement of the
callers and the nature of the GSP RPC commands.
The current supported reply policies are "callers don't care" and "receive
the entire message" according to the requirement of the callers. To
introduce a new policy, factor out the current RPC command reply polices.
Also, centralize the handling of the reply in a single function.
Factor out NVKM_GSP_RPC_REPLY_NOWAIT as "callers don't care" and
NVKM_GSP_RPC_REPLY_RECV as "receive the entire message". Introduce a
kernel doc to document the policies. Factor out
r535_gsp_rpc_handle_reply().
No functional change is intended for small GSP RPC commands. For large GSP
commands, the caller decides the policy of how to handle the returned GSP
RPC message.

Users can check the file "/sys/kernel/debug/dri/0/amdgpu_firmware_info"
to get information on the firmware loaded in the system. This file has
multiple acronyms that are not documented in the glossary. This commit
introduces some missing acronyms to the AMD glossary documentation. The
meaning of each acronym in this commit was extracted from code
documentation available in the following files:
- drivers/gpu/drm/amd/amdgpu/gfx_v7_0.c
- drivers/gpu/drm/amd/include/amd_shared.h
Changes since v1:
- Expand acronym meanings based on Alex Deucher suggestions.
