Once ras recovery is issued by ras sync flood interrupt or
ras controller interrupt, add this guard to bypass or execute
ras error count register harvest of all IPs.

Before ras recovery is issued, user could operate this debugfs
node to enable/disable the harvest of all RAS IPs' ras error
count registers, which will help keep hardware's registers'
status instead of cleaning up them.

GFX10 KIQ will hang if we try below steps:
modprobe amdgpu
rmmod amdgpu
modprobe amdgpu sched_hw_submission=4
Due to KIQ is always living there even after KMD unloaded
thus when doing the realod KIQ will crash upon its register
being programed by different values with the previous loading

With commit 72b6ede73623 ("dma-buf.rst: Document why indefinite fences are
a bad idea"), document generation warns:
Documentation/driver-api/dma-buf.rst:182: \
WARNING: Title underline too short.
Repair length of title underline to remove warning.
Fixes: 72b6ede73623 ("dma-buf.rst: Document
Just curious, but I noticed this new lock manager isn't being used because
of the definitive false return value in display/dc/dce/dmub_hw_lock_mgr.c:
should_use_dmub_lock.
Was this supposed to be enabled?

When '*sgt' is allocated, we must allocated 'sizeof(**sgt)' bytes instead
of 'sizeof(*sg)'. 'sg' (i.e. struct scatterlist) is smaller than
'sgt' (i.e struct sg_table), so this could lead to memory corruption.
Fixes: f44ffd677fb3 ("drm/amdgpu: add support for exporting VRAM using DMA-buf
v3")
Loongson processors have a writecombine issue that maybe failed to
write back framebuffer used with ATI Radeon or AMD GPU at times,
after commit 8a08e50cee66 ("drm: Permit video-buffers writecombine
mapping for MIPS"), there exists some errors such as blurred screen
and lockup, and so on.
