[PATCH 1/2] drm/i915: Flush execution tasklets before checking request status

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Rather than flushing the submission tasklets just before we sleep, flush
before we check the request status. Ideally this gives us a moment to
process the tasklets after sleeping just before we timeout.
