debugfs hang_hws is used by GPU reset test with HWS, for MES this crash
the kernel with NULL pointer access because dqm->packet_mgr is not setup
for MES path.
Skip GPU with MES for now, MES hang_hws debugfs interface will be
supported later.

The previous references to a non-existent `adev` parameter have been

If HW scheduler hangs and mode1 reset is used to recover GPU, KFD signal
user space to abort the processes. After process abort exit, user queues
still use the GPU to access system memory before h/w is reset while KFD
cleanup worker free system memory and free VRAM.
There is use-after-free race bug that KFD allocate and reuse the freed
system memory, and user queue write to the same system memory to corrupt
the data structure and cause driver crash.
To fix this race, KFD cleanup worker terminate user queues, then flush
reset_domain wq to wait for any GPU ongoing reset complete, and then
free outstanding BOs.

Prior to the addition of ring reset, the debug option
`debug_disable_soft_recovery` could be used to force a full device
reset. Now that we have ring reset, create a debug option to disable
them in amdgpu, forcing the driver to go with the full device
reset path again when both options are combined.
This option is useful for testing and debugging purposes when one wants
to test the full reset from userspace.

Null pointer dereference issue could occur when pipe_ctx->plane_state
is null. The fix adds a check to ensure 'pipe_ctx->plane_state' is not
null before accessing. This prevents a null pointer dereference.

'svm_range_cpu_invalidate_pagetables'

v2: To resolve this issue, the allocation of the process context buffer
(`proc_ctx_bo`) has been moved from the `add_queue_mes` function to the
`pqm_create_queue` function. This change ensures that the buffer is
allocated only when the first queue for a process is created and only if
the Micro Engine Scheduler (MES) is enabled. (Felix)
v3: Fix typo s/Memory Execution Scheduler (MES)/Micro Engine Scheduler
in commit message. (Lijo)

They are noops on GFX12. There is no suspend/resume all support
in firmware so the function doesn't do anything. KFD already
handles its own queues and they should already be unmapped at this
point so even if this runs, it's not doing anything.

The last use of optc3_fpu_set_vrr_m_const() was removed in 2022's
commit 64f991590ff4 ("drm/amd/display: Fix a compilation failure on PowerPC
caused by FPU code")
which removed the only caller (with a similar) name.
Remove it.

All dce command_table_helper's shares a copy-pasted collection
of copy-pasted functions, which are: phy_id_to_atom,
clock_source_id_to_atom_phy_clk_src_id, and engine_bp_to_atom.
This patch removes the multiple copy-pasted by moving them to
the command_table_helper.c and make the command_table_helper's
calls the functions implemented by the command_table_helper.c
instead.
The changes were not tested on actual hardware. I am only able
to verify that the changes keep the code compileable and do my
best to to look repeatedly if I am not actually changing any code.
This is the version 4 of the PATCH, fixed comments about
licence in the new files and the matches From email to
Signed-off-by email. Fixed comments about using
command_table_helper instead of creating a dce_common
