Chris Wilson e40dd22624 drm/i915/execlists: Listen to COMPLETE context event not ACTIVE_IDLE ... Since commit e1fee72c2e Author: Oscar Mateo <oscar.mateo@intel.com> Date: Thu Jul 24 17:04:40 2014 +0100 drm/i915/bdw: Avoid non-lite-restore preemptions execlists has listened to (ACTIVE_IDLE | ELEMENT_SWITCH) for detecting when one context completed and it either continued onto the next (in port 1) or idled. We would always see COMPLETE | ACTIVE_IDLE on the final context-switch event, but on recent gen it appears that we now get separate ACTIVE_IDLE and COMPLETE events. In particular, the ACTIVE_IDLE events may not be coupled to a context (since it is a general state rather than a specific context completion event). v2: Update the history, execlists did originally start out by listening to the COMPLETE event not ACTIVE_IDLE. v3: Update preempt completion test to also use COMPLETE not ACTIVE_IDLE.
