Subject: [PATCH v3 1/8] drm/i915: Assert that we don't submit to execlists whilst a preempt is pending
Date: Tue, 24 Jan 2017 11:00:02 +0000 [thread overview]
Message-ID: <20170124110009.28947-1-chris@chris-wilson.co.uk> (raw)
To complement the check in execlists_elsp_ready(), also assert that we
don't submit the same context while it has a lite restore still pending.
