Summary
drm/amdgpu: force complete the KIQ ring fences on reset
Details

In the Linux kernel, the following vulnerability has been resolved:

drm/amdgpu: force complete the KIQ ring fences on reset

Like the MES scheduler ring, the KIQ ring sets no_scheduler = true and uses a polling fence, so it is skipped by the force-completion loop in amdgpu_device_pre_asic_reset(). Its hw fence value lives in wb (GTT) memory and survives a MODE1 reset while fence_drv.sync_seq keeps advancing, so after a reset the first KIQ submission can poll forever on a seq that is never written back.

Force complete the KIQ ring fences too so their hw fence is realigned to sync_seq.
