In the Linux kernel, the following vulnerability has been resolved:
drm/amdgpu: skip gfx switch_power_profile during GPU reset
During resume from GPU reset, the gfx idle work may invoke switch_power_profile
before the reset completes. This causes the following assert error because the
register access occurs without first releasing the GPU reset semaphore:
