Description
In the Linux kernel, the following vulnerability has been resolved: drm/xe: don't WARN on kernel job timeout when device already wedged igt@xe_wedged@wedged-at-any-timeout wedges the device in mode 2 (UPON_ANY_HANG_NO_RESET) and then rebinds the driver. During unbind, a GSC proxy kernel submission can still time out; with the device wedged and the GuC CT stopped it can never complete, so its kernel job times out. Tile0: GT1: Kernel-submitted job timed out WARNING: drivers/gpu/drm/xe/xe_guc_submit.c:... at guc_exec_queue_timedout_job() Workqueue: gt-ordered-wq drm_sched_job_timedout Killed queues skip guc_submit_hint_wedged(), leaving 'wedged' false even though the device is already wedged. The timeout handler then treats the kernel queue timeout as unexpected and taints the kernel. Honour an already-wedged device even for killed queues so the expected teardown timeout no longer trips the WARN. (cherry picked from commit a1c1dbd0f047bb05de6aaf6abe9103031179bf19)
