Since its inception, 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).

Long long time ago we also looked at GEN8_CTX_STATUS_COMPLETE.
I don't know about these 'recent' gens, but this change shouldn't make 
things worse.

    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.

Since commit e1fee72c2ea2e9c0c6e6743d32a6832f21337d6c
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.
