Subject: [PATCH i-g-t v3 4/6] igt/gem_ctx_param_basic: Updated to support scheduler priority interface
Date: Thu, 10 Mar 2016 11:03:32 +0000	[thread overview]
Message-ID: <1457607814-18751-5-git-send-email-derek.j.morton@intel.com> (raw)
In-Reply-To: <1457607814-18751-1-git-send-email-derek.j.morton@intel.com>

From: John Harrison <John.C.Harrison@Intel.com>

The GPU scheduler has added an execution priority level to the context
object. There is an IOCTL interface to allow user apps/libraries to
set this priority. This patch updates the context paramter IOCTL test
to include the new interface.

For: VIZ-1587
Signed-off-by: John Harrison <John.C.Harrison@Intel.com>
