Subject: [Intel-gfx] [PATCH 1/4] drm/i915: Don't set queue-priority hint when supressing the reschedule
Date: Tue, 19 May 2020 00:14:04 +0100 [thread overview]
Message-ID: <20200518231407.6837-1-chris@chris-wilson.co.uk> (raw)
We recorded the execlists->queue_priority_hint update for the inflight
request without kicking the tasklet. The next submitted request then
failed to be scheduled as it had a lower priority than the hint, leaving
the HW runnning with only the inflight request.
Fixes: 6cebcf746f3f ("drm/i915: Tweak scheduler's kick_submission()")
Signed-off-by: Chris Wilson <chris@chris-wilson.co.uk>
