Subject: [Intel-gfx] [PATCH 2/6] drm/i915: Restrict sentinel requests further
Date: Tue, 16 Mar 2021 16:23:22 +0000 [thread overview]
Message-ID: <20210316162326.1994039-3-tvrtko.ursulin@linux.intel.com> (raw)
In-Reply-To: <20210316162326.1994039-1-tvrtko.ursulin@linux.intel.com>
From: Tvrtko Ursulin <tvrtko.ursulin@intel.com>
Disallow sentinel requests follow previous sentinels to make request
cancellation work better when faced with a chain of requests which have
all been marked as in error.
