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.\n\nForce complete the KIQ ring fences too so their hw fence is realigned to\nsync_seq."
