Subject: [PATCH 03/10] drm/i915: Update i915.reset to handle engine resets
Date: Wed, 11 Jan 2017 20:18:10 -0800 [thread overview]
Message-ID: <20170112041817.1102-4-michel.thierry@intel.com> (raw)
In-Reply-To: <20170112041817.1102-1-michel.thierry@intel.com>
From: Arun Siluvery <arun.siluvery@linux.intel.com>
In preparation for engine reset work update this parameter to handle more
than one type of reset. Default at the moment is still full gpu reset.
