From abdea2847acfe41313620a5359940522990018e3 Mon Sep 17 00:00:00 2001 From: Jonathan Cavitt Date: Fri, 10 May 2024 12:45:39 -0700 Subject: drm/xe/xe_guc_submit: Allow lr exec queues to be banned LR queues currently don't get banned during a GT/GuC reset because they lack a job. Though they don't have a job to detect the reset status of, it's still possible to tell when they should be banned by looking at the LRC: if the LRC head and tail don't match, then the exec queue should be banned and cleaned up. This also requires swapping the usage of xe_sched_tdr_queue_imm with xe_guc_exec_queue_trigger_cleanup, as the former is specific to non-lr exec queues.
