Subject: [Intel-gfx] [PATCH 08/27] drm/i915/selftests: Add a cancel request selftest that triggers a reset
Date: Wed, 25 Aug 2021 20:23:08 -0700 [thread overview]
Message-ID: <20210826032327.18078-9-matthew.brost@intel.com> (raw)
In-Reply-To: <20210826032327.18078-1-matthew.brost@intel.com>
Add a cancel request selftest that results in an engine reset to cancel
the request as it is non-preemptable. Also insert a NOP request after
the cancelled request and confirm that it completely successfully.
