635c659fce drm/amdgpu: Use dbg level for VBIOS check messages 
Driver has different ways to fetch VBIOS. If one of the methods doesn't
find an authentic one, it will show misleading info messages eventhough
a subsequent method finds a valid VBIOS. Keep the message level at debug

2ae520cb12 drm/amdgpu: don't access invalid sched 
Since 2320c9e6a7 ("drm/sched: memset() 'job' in drm_sched_job_init()")
accessing job->base.sched can produce unexpected results as the initialisation
of (*job)->base.sched done in amdgpu_job_alloc is overwritten by the
memset.

This commit fixes an issue when a CS would fail validation and would
be rejected after job->num_ibs is incremented. In this case,
amdgpu_ib_free(ring->adev, ...) will be called, which would crash the
machine because the ring value is bogus.

To fix this, pass a NULL pointer to amdgpu_ib_free(): we can do this
because the device is actually not used in this function.

The next commit will remove the ring argument completely.

Remove the logically dead code in the last return statement of

res is already checked for a negative value earlier. Replace
return res < 0 ? res : 0; with return 0 to improve clarity.

Add support for the drm_panic module, which displays a pretty user
friendly message on the screen when a Linux kernel panic occurs.

Adapt Lu Yao's code to use common helpers derived from
Jocelyn's patch.  This extends the non-DC code to enable
access to non-CPU accessible VRAM and adds support for
other DCE versions.

55f4139b65 drm/amd/amdgpu: Add Annotations to Process Isolation functions 
This update adds explanations to key functions that manage how the
Kernel Fusion Driver (KFD) and Kernel Graphics Driver (KGD) share the
GPU.

amdgpu_gfx_enforce_isolation_wait_for_kfd: Controls the waiting period
for KFD to ensure it takes turns with KGD in using the GPU. It uses a
mutex to safely manage shared data, like timing and state, and tracks
when KFD starts and stops waiting.

amdgpu_gfx_enforce_isolation_ring_begin_use: Ensures KFD has enough time
to run before new tasks are submitted to the GPU ring. It uses a mutex
to synchronize access and may adjust the KFD scheduler.

amdgpu_gfx_enforce_isolation_ring_end_use: Handles cleanup and state
updates when finishing the use of a GPU ring. It may also adjust the KFD
scheduler, using a mutex to manage shared data access.

a69f4cc278 drm/amd/amdgpu: Add Descriptions to Process Isolation and Cleaner Shader Sysfs Functions 
This update adds explanations to key functions related to process
isolation and cleaner shader execution sysfs interfaces.

- `amdgpu_gfx_set_run_cleaner_shader`: Describes how to manually run a
  cleaner shader, which clears the Local Data Store (LDS) and General
  Purpose Registers (GPRs) to ensure data isolation between GPU workloads.

- `amdgpu_gfx_get_enforce_isolation`: Describes how to query the current
  settings of the 'enforce_isolation' feature for each GPU partition.

- `amdgpu_gfx_set_enforce_isolation`: Describes how to enable or disable
  process isolation for GPU partitions through the sysfs interface.
