[Why]
When kernel documentation is generated the enum values themselves don't
end up in the documentation. This makes browsing them in HTML a lot
less useful.
[How]
Copy DC_DEBUG_MASK and DC_FEATURE_MASK enum values into matching kdoc
comments.

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.

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
v6: add more documentation

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.

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.

Provide the lower level code for PIPEDMC based flip queue.
We'll use the so called semi-full flip queue mode where the
PIPEDMC will start the provided DSB on a scanline a little
ahead of the vblank. We need to program the triggering scanline
early enough so that the DSB has enough time to complete writing
all the double buffered registers before they get latched (at
start of vblank).
The firmware implements several queues:
- 3 "plane queues" which execute a single DSB per entry
- 1 "general queue" which can apparently execute 2 DSBs per entry
- 1 vestigial "fast queue" that replaced the "simple flip queue"
on ADL+, but this isn't supposed to be used due to issues.
But we only need a single plane queue really, and we won't actually
use it as a real queue because we don't allow queueing multiple commits
ahead of time. So the whole thing is perhaps useless. I suppose
there migth be some power saving benefits if we would get the flip
scheduled by userspace early and then could keep some hardware powered
off a bit longer until the DMC kicks off the flipq programming. But that
is pure speculation at this time and needs to be proven.
The code to hook up the flip queue into the actual atomic commit
path will follow later.
TODO: need to think how to do the "wait for DMC firmware load" nicely
need to think about VRR and PSR
etc.
v2: Don't write DMC_FQ_W2_PTS_CFG_SEL on pre-lnl
Don't oops at flipq init if there is no dmc
v3: Adapt to PTL+ flipq changes (different queue entry
layout, different trigger event, need VRR TG)
Use the actual CDCLK frequency
Ask the DSB code how long things are expected to take
v3: Adjust the cdclk rounding (docs are 100% vague, Windows
rounds like this)
Initialize some undocumented magic DMC variables on PTL
v4: Use PIPEDMC_FQ_STATUS for busy check (the busy bit in
PIPEDMC_FQ_CTRL is apparently gone on LNL+)
Based the preempt timeout on the max exec time
Preempt before disabling the flip queue
Order the PIPEDMC_SCANLINECMP* writes a bit more carefully
Fix some typos
v5: Try to deal with some clang-20 div-by-zero false positive (Nathan)
Add some docs (Jani)

The migration functionality and track-keeping of per-pagemap VRAM
mapped to the CPU mm is not per GPU_vm, but rather per pagemap.
This is also reflected by the functions not needing the drm_gpusvm
structures. So move to drm_pagemap.
With this, drm_gpusvm shouldn't really access the page zone-device-data
since its meaning is internal to drm_pagemap. Currently it's used to
reject mapping ranges backed by multiple drm_pagemap allocations.
For now, make the zone-device-data a void pointer.
Alter the interface of drm_gpusvm_migrate_to_devmem() to ensure we don't
pass a gpusvm pointer.
Rename CONFIG_DRM_XE_DEVMEM_MIRROR to CONFIG_DRM_XE_PAGEMAP.
Matt is listed as author of this commit since he wrote most of the code,
and it makes sense to retain his git authorship.
Thomas mostly moved the code around.
v3:
- Kerneldoc fixes (CI)
- Don't update documentation about how the drm_pagemap
migration should be interpreted until upcoming
patches where the functionality is implemented.
(Matt Brost)
v4:
- More kerneldoc fixes around timeslice_ms

[Why]
Brightness programming may involve a conversion of a user requested
brightness against what was in a custom brightness curve. The values
might not match what a user programmed.
[How]
Add a new trace event to show specific converted brightness values.

A few new dependencies are required to remove some of the TODO items:
- A way to safely convert from byte slices to types implementing
`FromBytes`,
- A way to obtain slices and write into a `CoherentAllocation`,
- Several improvements to the `register!()` macro,
- Alignment operations to powers of two, and an equivalent to the C
`fls`,
- Support for `xa_alloc` in the XAlloc bindings.
Some items have also become obsolete:
- The auxiliary bus abstractions have been implemented and are in use,
- The ELF utilities are not considered for being part of the core kernel
bindings anymore.
- VBIOS, falcon and GPU timer have been completed.
We now have quite a few TODO entries in the code, so annotate them with
a 4 letter code representing the corresponding task in `todo.rst`. This
allows to easily find which part of the code corresponds to a given
entry (and conversely).

GSP message queue docs has been moved following RPC handling split in
commit 8a8b1ec5261f20 ("drm/nouveau/gsp: split rpc handling out on its
own"), before GSP-RM implementation is versioned in commit c472d828348caf
("drm/nouveau/gsp: move subdev/engine impls to subdev/gsp/rm/r535/").
However, the kernel-doc reference in nouveau docs is left behind, which
triggers htmldocs warnings:
ERROR: Cannot find file ./drivers/gpu/drm/nouveau/nvkm/subdev/gsp/r535.c
WARNING: No kernel-doc for file ./drivers/gpu/drm/nouveau/nvkm/subdev/gsp/r535.c
Update the reference.
