DCN60 supports cursor offload to DMU.
Request cursor offload in amdgpu_dm_init and initialize it after DMUB is up
(dc_dmub_srv_cursor_offload_init), which should be picked up by all the
ASICs that support cursor offload in the dcnX_resouce.c.

why:
When a display is disabled the surviving DSC stream is committed with no
planes but the dynamic ODM policy still expands it to a four to one
combine. The added plane-less segments skip program_pipe so their OPP
formatter is never configured. The DPG blank then feeds an unprogrammed
formatter and the OPTC input underflows which flashes grey on screen.
how:
Program the OPP formatter for each plane-less OPP head in update_odm and
update_odm_sequence the same way program_pipe does for planed pipes. Both
function pointers are checked for null before calling. Every ODM segment
now feeds valid data to the OPTC so the four to one combine no longer
underflows.

amdgpu_gem_ualink_handle_ioctl() dereferences adev->ualink.info before
validating it, but that structure is only allocated when the UALink IP
block is present, which is currently added only for GFX 12.1 only. The
ioctl is registered for every amdgpu device with DRM_RENDER_ALLOW, so
on any other ASIC a render node user can oops the kernel with a single
call.
Return -EOPNOTSUPP when the UALink software state is absent.

[WHY]
Hotplugging an HDMI FRL sink can wedge DMCUB when a poll-driven retrain
lands on a link whose PHY has just been torn down. The status polling
path can program PHY EQ on the disabled PHY, after which the sink SCDC
reads back version 0 and the display fails to light up.
[HOW]
Skip FRL status polling unless the link is actively driving a stream.
The check runs under dc_lock, so it is serialized with link detection
and modesets while the PHY is being torn down.

Note that the soft reset code for GMC v6-v7 was never
called from anywhere, so there is no loss of functionality
from this commit. The implementation looks plausible but
it was never enabled or tested, and unlikely to be useful.
We should only reset the memory controller during ASIC reset
and otherwise leave it alone. Resetting the memory controller
can break everything and risks losing the contents of VRAM
(it's unclear if VRAM is lost or not, but it's likely).

DMs still call dc_hardware_init and dc_hardware_release while Core 2
lands next to legacy. Those entry points live in dc/dc_api_dispatch:
LEGACY calls the old bodies directly, CORE2 uses core2_funcs. dc_create
allocates struct dc2 and returns the inner dc (TO_DC2). The shim only
records selection; dc_construct still constructs Core2. No dispatch
fields on public struct dc, and no architect spec edits.
TO_DC2 is a typed upcast (struct dc is the first member of struct dc2).
Shim headers are included for UNIT_TEST as well as production so TO_DC2
is defined when core_gtest compiles dc.c.

[WHY]
The HDMI FRL status polling work can run concurrently with link detect
after an unplug/replug. Both paths access the same link through DDC and may
perform FRL link training, while the polling path also reads link state
without holding dc_lock.
[HOW]
Use mutex_trylock() to serialize the complete link walk, FRL status
polling, and retraining sequence with dc_lock. If the lock is busy,
defer the background poll to the next 200ms cycle instead of blocking
an active detect, modeset, or flip.

CWSR ranges use the always mapped flag and only need a mapping on the
GPU running the queue. However, svm_range_validate_and_map now updates
the mapping on every GPU with the ACCESS attribute, which is all
supported GPUs when XNACK is on. After the range is prefetched to VRAM,
those GPUs may span different XGMI hives, so the page owner mismatches
and is set to NULL. hmm_range_fault then tries to migrate the VRAM
pages back to system memory, but svm_migrate_to_ram skips it because
migrating pages back to system memory is not allowed while the GPU
mapping is being updated, so the CPU page fault is never resolved.
Only map to the ACCESS GPUs if the range is not mapped to any GPU and
is not in VRAM.
