Subject: [Intel-gfx] [PATCH 3/3] drm/i915/gem: Peek at the inflight context
Date: Fri, 25 Dec 2020 20:49:38 +0000	[thread overview]
Message-ID: <20201225204938.20248-3-chris@chris-wilson.co.uk> (raw)
In-Reply-To: <20201225204938.20248-1-chris@chris-wilson.co.uk>

If supported by the backend, we can quickly look at the context's
inflight engine rather than search along the active list to confirm.
