9bdbf7eb25 DRM Rust changes for v7.1-rc1 
- DMA:
   - Rework the DMA coherent API: introduce Coherent<T> as a generalized
     container for arbitrary types, replacing the slice-only
     CoherentAllocation<T>. Add CoherentBox for memory initialization
     before exposing a buffer to hardware (converting to Coherent when
     ready), and CoherentHandle for allocations without kernel mapping.
 
   - Add Coherent::init() / init_with_attrs() for one-shot initialization
     via pin-init, and from-slice constructors for both Coherent and
     CoherentBox
 
   - Add uaccess write_dma() for copying from DMA buffers to userspace
     and BinaryWriter support for Coherent<T>
 
 - DRM:
   - Add GPU buddy allocator abstraction
 
   - Add DRM shmem GEM helper abstraction
 
   - Allow drm::Device to dispatch work and delayed work items to driver
     private data
 
   - Add impl_aref_for_gem_obj!() macro to reduce GEM refcount
     boilerplate, and introduce DriverObject::Args for constructor
     context
 
   - Add dma_resv_lock helper and raw_dma_resv() accessor on GEM objects
 
   - Clean up imports across the DRM module
 
 - I/O:
   - Merged via a signed tag from the driver-core tree: register!() macro
     and I/O infrastructure improvements (IoCapable refactor, RelaxedMmio
     wrapper, IoLoc trait, generic accessors, write_reg /
     LocatedRegister)
 
 - Nova (Core):
   - Fix and harden the GSP command queue: correct write pointer
     advancing, empty slot handling, and ring buffer indexing; add mutex
     locking and make Cmdq a pinned type; distinguish wait vs no-wait
     commands
 
   - Add support for large RPCs via continuation records, splitting
     oversized commands across multiple queue slots
 
   - Simplify GSP sequencer and message handling code: remove unused
     trait and Display impls, derive Debug and Zeroable where applicable,
     warn on unconsumed message data
 
   - Refactor Falcon firmware handling: create DMA objects lazily, add
     PIO upload support, and use the Generic Bootloader to boot FWSEC on
     Turing
 
   - Convert all register definitions (PMC, PBUS, PFB, GC6, FUSE, PDISP,
     Falcon) to the kernel register!() macro; add bounded_enum macro to
     define enums usable as register fields
 
   - Migrate all DMA usage to the new Coherent, CoherentBox, and
     CoherentHandle APIs
 
   - Harden firmware parsing with checked arithmetic throughout FWSEC,
     Booter, RISC-V parsing paths
 
   - Add debugfs support for reading GSP-RM log buffers; replace
     module_pci_driver!() with explicit module init to support
     module-level debugfs setup
 
   - Fix auxiliary device registration for multi-GPU systems
 
   - Various cleanups: import style, firmware parsing refactoring,
     framebuffer size logging
 
 - Rust:
   - Add interop::list module providing a C linked list interface
 
   - Extend num::Bounded with shift operations, into_bool(), and const
     get() to support register bitfield manipulation
 
   - Enable the generic_arg_infer Rust feature and add EMSGSIZE error
     code
 
 - Tyr:
   - Adopt vertical import style per kernel Rust guidelines

df03d7c2bb drm/xe: Document GT statistics 
In the context of porting applications to SVM, the Xe GT statistics are
used by application developers to validate expected behavior such as
proper alignment, page fault count and migrations. As those statistics
are made for kernel developers, they assume good understanding of driver
internals, which is not always the case on the application side.
Therefore, this commit documents the usage of GT statistics and clarifies
the meaning of identifiers which correspond to the values exposed via
debugfs. Documentation is close to identifiers declaration to make it
easier to maintain when adding new entries in the future.

9886005f89 drm/simple-kms: Deprecate simple-kms helpers 
Deprecate simple-encoder and simple-display-pipe helpers in favor of
regular atomic helpers. Remove the related documentation. Add TODO
item for converting the remaining drivers.

These helpers have been deprecated for years and many drivers have
been updated to not use them. Still there are a few left and we
occasionally receive new drivers build upon them. Marking them as
deprecated will hopefully resolve these problems. The TODO items
should be easy enough for getting new voluteers started on DRM driver
development.

drm/ras: Introduce the DRM RAS infrastructure over generic netlink 
Introduces the DRM RAS infrastructure over generic netlink.

The new interface allows drivers to expose RAS nodes and their
associated error counters to userspace in a structured and extensible
way. Each drm_ras node can register its own set of error counters, which
are then discoverable and queryable through netlink operations. This
lays the groundwork for reporting and managing hardware error states
in a unified manner across different DRM drivers.

Currently it only supports error-counter nodes. But it can be
extended later.

The registration is also not tied to any drm node, so it can be
used by accel devices as well.

It uses the new and mandatory YAML description format stored in
Documentation/netlink/specs/. This forces a single generic netlink
family namespace for the entire drm: "drm-ras".
But multiple-endpoints are supported within the single family.

Any modification to this API needs to be applied to
Documentation/netlink/specs/drm_ras.yaml before regenerating the
code:

$ tools/net/ynl/pyynl/ynl_gen_c.py --spec \
 Documentation/netlink/specs/drm_ras.yaml --mode uapi --header \
 -o include/uapi/drm/drm_ras.h

ba110db8e1 gpu: Move DRM buddy allocator one level up (part two) 
Move the DRM buddy allocator one level up so that it can be used by GPU
drivers (example, nova-core) that have usecases other than DRM (such as
VFIO vGPU support). Modify the API, structures and Kconfigs to use
"gpu_buddy" terminology. Adapt the drivers and tests to use the new API.

The commit cannot be split due to bisectability, however no functional
change is intended. Verified by running K-UNIT tests and build tested
various configurations.

I've also just nuked drm_random library, that stuff needs to be done
elsewhere and only the buddy tests seem to be using it].

Move enable/disable GuC RC logic into the new file. This will
allow us to independently enable/disable GuC RC and not rely
on SLPC related functions. GuC already provides separate H2G
interfaces to setup GuC RC and SLPC.

a592a36e49 Documentation: use a source-read extension for the index link boilerplate 
The root document usually has a special :ref:`genindex` link to the
generated index. This is also the case for Documentation/index.rst. The
other index.rst files deeper in the directory hierarchy usually don't.

For SPHINXDIRS builds, the root document isn't Documentation/index.rst,
but some other index.rst in the hierarchy. Currently they have a
".. only::" block to add the index link when doing SPHINXDIRS html
builds.

This is obviously very tedious and repetitive. The link is also added to
all index.rst files in the hierarchy for SPHINXDIRS builds, not just the
root document.

Put the boilerplate in a sphinx-includes/subproject-index.rst file, and
include it at the end of the root document for subproject builds in an
ad-hoc source-read extension defined in conf.py.

For now, keep having the boilerplate in translations, because this
approach currently doesn't cover translated index link headers.

AMDGPU heavily relies on ring buffers to manage its components; as a
result, it has an elaborate mechanism of operation with multiple details
around it. This commit introduces new documentation on ring buffers,
detailing their management and expanding the explanation of Enforce
isolation. Finally, this commit also adds the documentation available in
the amdgpu_ring.c file to it.

74afeb8128 drm/vblank: Add vblank timer 
The vblank timer simulates a vblank interrupt for hardware without
support. Rate-limits the display update frequency.

DRM drivers for hardware without vblank support apply display updates
ASAP. A vblank event informs DRM clients of the completed update.
Userspace compositors immediately schedule the next update, which
creates significant load on virtualization outputs. Display updates
are usually fast on virtualization outputs, as their framebuffers are
in regular system memory and there's no hardware vblank interrupt to
throttle the update rate.

The vblank timer is a HR timer that signals the vblank in software.
It limits the update frequency of a DRM driver similar to a hardware
vblank interrupt. The timer is not synchronized to the actual vblank
interval of the display.

The code has been adopted from vkms, which added the funtionality
in commit 3a0709928b ("drm/vkms: Add vblank events simulated by
hrtimers").

The new implementation is part of the existing vblank support,
which sets up the timer automatically. Drivers only have to start
and cancel the vblank timer as part of enabling and disabling the
CRTC. The new vblank helper library provides callbacks for struct
drm_crtc_funcs.

The standard way for handling vblank is to call drm_crtc_handle_vblank().
Drivers that require additional processing, such as vkms, can init
handle_vblank_timeout in struct drm_crtc_helper_funcs to refer to
their timeout handler.

There's a possible deadlock between drm_crtc_handle_vblank() and
hrtimer_cancel(). [1] The implementation avoids to call hrtimer_cancel()
directly and instead signals to the timer function to not restart
itself.

v4:
- fix possible race condition between timeout and atomic commit (Michael)
v3:
- avoid deadlock when cancelling timer (Ville, Lyude)
v2:
- implement vblank timer entirely in vblank helpers
- downgrade overrun warning to debug
- fix docs

fb24aaf541 drm/dumb-buffers: Provide helper to set pitch and size 
Add drm_modes_size_dumb(), a helper to calculate the dumb-buffer
scanline pitch and allocation size. Implementations of struct
drm_driver.dumb_create can call the new helper for their size
computations.

There is currently quite a bit of code duplication among DRM's
memory managers. Each calculates scanline pitch and buffer size
from the given arguments, but the implementations are inconsistent
in how they treat alignment and format support. Later patches will
unify this code on top of drm_mode_size_dumb() as much as possible.

drm_mode_size_dumb() uses existing 4CC format helpers to interpret
the given color mode. This makes the dumb-buffer interface behave
similar the kernel's video= parameter. Current per-driver implementations
again likely have subtle differences or bugs in how they support color
modes.

The dumb-buffer UAPI is only specified for known color modes. These
values describe linear, single-plane RGB color formats or legacy index
formats. Other values should not be specified. But some user space
still does. So for unknown color modes, there are a number of known
exceptions for which drm_mode_size_dumb() calculates the pitch from
the bpp value, as before. All other values work the same but print
an error.

v6:
- document additional use cases for DUMB_CREATE2 in TODO list (Tomi)
- fix typos in documentation (Tomi)
v5:
- check for overflows with check_mul_overflow() (Tomi)
v4:
- use %u conversion specifier (Geert)
- list DRM_FORMAT_Dn in UAPI docs (Geert)
- avoid dmesg spamming with drm_warn_once() (Sima)
- add more information about bpp special case (Sima)
- clarify parameters for hardware alignment
- add a TODO item for DUMB_CREATE2
v3:
- document the UAPI semantics
- compute scanline pitch from for unknown color modes (Andy, Tomi)

a841614e60 gpu: nova-core: firmware: process and prepare the GSP firmware 
The GSP firmware is a binary blob that is verified, loaded, and run by
the GSP bootloader. Its presentation is a bit peculiar as the GSP
bootloader expects to be given a DMA address to a 3-levels page table
mapping the GSP firmware at address 0 of its own address space.

Prepare such a structure containing the DMA-mapped firmware as well as
the DMA-mapped page tables, and a way to obtain the DMA handle of the
level 0 page table.

Then, move the GSP firmware instance from the `Firmware` struct to the
`start_gsp` method since it doesn't need to be kept after the GSP is
booted.

As we are performing the required ELF section parsing and radix3 page
table building, remove these items from the TODO file.

drm: Add a vendor-specific recovery method to drm device wedged uevent 
Address the need for a recovery method (firmware flash on Firmware errors)
introduced in the later patches of Xe KMD.
Whenever XE KMD detects a firmware error, a firmware flash is required to
recover the device to normal operation.

The initial proposal to use 'firmware-flash' as a recovery method was
not applicable to other drivers and could cause multiple recovery
methods specific to vendors to be added.
To address this a more generic 'vendor-specific' method is introduced,
guiding users to refer to vendor specific documentation and system logs
for detailed vendor specific recovery procedure.

Add a recovery method 'WEDGED=vendor-specific' for such errors.
Vendors must provide additional recovery documentation if this method
is used.

It is the responsibility of the consumer to refer to the correct vendor
specific documentation and usecase before attempting a recovery.

For example: If driver is XE KMD, the consumer must refer
to the documentation of 'Device Wedging' under 'Documentation/gpu/xe/'.

v2: fix documentation (Raag)
v3: add more details to commit message (Sima, Rodrigo, Raag)
    add an example script to the documentation (Raag)
v4: use consistent naming (Raag)
v5: fix commit message

0988099646 gpu: nova-core: register: add support for relative array registers 
Add support for declaring arrays of registers available from a variable
base. This is effectively a combination of the relative and array
registers features.

nova-core does not make much use of this yet, but it will become helpful
to have for GSP boot.

af10924fc4 gpu: nova-core: register: redesign relative registers 
The relative registers are currently very unsafe to use: callers can
specify any constant as the base address for access, meaning they can
effectively interpret any I/O address as any relative register.

Ideally, valid base addresses for a family of registers should be
explicitly defined in the code, and could only be used with the relevant
registers

This patch changes the relative register declaration from e.g.:

    register!(CPU_CTL @ +0x0000010, "CPU core control" {
        0:0     start as bool, "Start the CPU core";
    });

into:

    register!(CPU_CTL @ CpuCtlBase[0x10], "CPU core control" {
        0:0     start as bool, "Start the CPU core";
    });

Where `CpuCtlBase` is the name of a ZST used as a parameter of the
`RegisterBase<>` trait to define a trait unique to a class of register.
This specialized trait is then implemented for every type that provides
a valid base address, enabling said types to be passed as the base
address provider for the register's I/O accessor methods.

This design thus makes it impossible to pass an unexpected base address
to a relative register, and, since the valid bases are all known at
compile-time, also guarantees that all I/O accesses are done within the
valid bounds of the I/O range.

[acourbot@nvidia.com: add example in the commit log.]
