drm/amdgpu: Add fallback to pipe reset if KCQ ring reset fails

Browse source

[ Upstream commit 7469567d88 ]

Add a fallback mechanism to attempt pipe reset when KCQ reset
fails to recover the ring. After performing the KCQ reset and
queue remapping, test the ring functionality. If the ring test
fails, initiate a pipe reset as an additional recovery step.

v2: fix the typo (Lijo)
v3: try pipeline reset when kiq mapping fails (Lijo)
