In LR/preempt-fence VM mode, this can lead to missed TLB\ninvalidation and page faults during userptr invalidation tests.\n\nRestore unconditional schedule toggling on suspend so the context-switch\nTLB flush is always performed.\n\nThis optimization will be reintroduced with a fix that does not skip\nsuspend in LR/preempt-fence VM mode.\n\n(cherry picked from commit 6a1e7934d9a6cf46aecae00a99c2603d1295e170)"}],"metrics":[{"cvssV3_1":{"version":"3.1","vectorString":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H","baseScore":7.8,"baseSeverity":"HIGH"}}],"affected":[{"product":"Linux","vendor":"Linux","defaultStatus":"unaffected","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","programFiles":["drivers/gpu/drm/xe/xe_exec_queue.h","drivers/gpu/drm/xe/xe_guc_submit.c","drivers/gpu/drm/xe/xe_hw_engine_group.c"],"versions":[{"version":"8533051ce92015e9cc6f75e0d52119b9d91610b6","lessThan":"b69b715f48ac7e802c89ed5924795c5b055da91e","status":"affected","versionType":"git"},{"version":"8533051ce92015e9cc6f75e0d52119b9d91610b6","lessThan":"fa7c84726dc217ce0c183926ef9411636c7a2213","status":"affected","versionType":"git"}]},{"product":"Linux","vendor":"Linux","defaultStatus":"affected","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","programFiles":["drivers/gpu/drm/xe/xe_exec_queue.h","drivers/gpu/drm/xe/xe_guc_submit.c","drivers/gpu/drm/xe/xe_hw_engine_group.c"],"versions":[{"version":"7.0","status":"affected"},{"version":"0","lessThan":"7.0","status":"unaffected","versionType":"semver"},{"version":"7.0.13","lessThanOrEqual":"7.0.*","status":"unaffected","versionType":"semver"},{"version":"7.1","lessThanOrEqual":"*","status":"unaffected","versionType":"original_commit_for_fix"}]}],"cpeApplicability":[{"nodes":[{"operator":"OR","negate":false,"cpeMatch":[{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"7.0","versionEndExcluding":"7.0.13"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"7.0","versionEndExcluding":"7.1"}]}]}],"references":[{"url":"https://git.kernel.org/stable/c/b69b715f48ac7e802c89ed5924795c5b055da91e"},{"url":"https://git.kernel.org/stable/c/fa7c84726dc217ce0c183926ef9411636c7a2213"}],"title":"Revert \"drm/xe: Skip exec queue schedule toggle if queue is idle during suspend\"","x_generator":{"engine":"bippy-1.2.0"}}}}
