Chris Wilson a8c51ed22b drm/i915/gt: Try to more gracefully quiesce the system before resets ... If we are doing a normal GPU reset triggered after detecting a long period of stalled work, we can take our time and allow the engines to quiesce. Since we've stopped submission to the engine, and if we wait long enough an innocent context should complete, leaving the engine idle. So by waiting a short amount of time, we should prevent clobbering other users when resetting a stuck context.
