Subject: [Intel-gfx] [PATCH 15/22] drm/i915: Drop I915_IDLE_ENGINES_TIMEOUT
Date: Mon,  4 May 2020 05:48:56 +0100	[thread overview]
Message-ID: <20200504044903.7626-15-chris@chris-wilson.co.uk> (raw)
In-Reply-To: <20200504044903.7626-1-chris@chris-wilson.co.uk>

This timeout is only used in one place, to provide a tiny bit of grace
for slow igt to cleanup after themselves. If we are a bit stricter and
opt to kill outstanding requsts rather than wait, we can speed up igt by
not waiting for 200ms after a hang.
