drm\/amdgpu: force complete the KIQ ring fences on reset<\/p>\n
Like the MES scheduler ring, the KIQ ring sets no_scheduler = true and uses a
\npolling fence, so it is skipped by the force-completion loop in
\namdgpu_device_pre_asic_reset(). Its hw fence value lives in wb (GTT) memory and
\nsurvives a MODE1 reset while fence_drv.sync_seq keeps advancing, so after a
\nreset the first KIQ submission can poll forever on a seq that is never written
\nback.<\/p>\n
Force complete the KIQ ring fences too so their hw fence is realigned to
\nsync_seq.<\/p>\n","protected":false},"excerpt":{"rendered":"
