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.","cvssScore":null,"cvssSeverity":null,"cvssVector":null,"cwes":[],"vendors":[],"products":[],"references":[{"url":"https://git.kernel.org/stable/c/bdd6a58743e00ebc6d52b9cdf9aafb4e535e0b71","tags":[]},{"url":"https://git.kernel.org/stable/c/fd65d1742992361fc2201ecb4e43411e6e417fcb","tags":[]}],"exploitRefs":[],"hasPoc":false,"ai":null}
