Subject: [PATCH 2/3] drm/tegra: Add sync file support to submit interface
Date: Thu,  9 Mar 2017 19:57:17 +0200	[thread overview]
Message-ID: <20170309175718.14843-3-mperttunen@nvidia.com> (raw)
In-Reply-To: <20170309175718.14843-1-mperttunen@nvidia.com>

Adds ability to pass sync file based prefences and get back
sync file based postfences during job submission. Both
fence fd's are passed in the `fence` field. A new `flags`
field is used to specify if the prefence should be waited
or a postfence created.
