Subject: [PATCH i-g-t 24/29] igt/perf: fix rc6 test
Date: Tue, 25 Apr 2017 15:32:56 -0700	[thread overview]
Message-ID: <20170425223301.23733-25-lionel.g.landwerlin@intel.com> (raw)
In-Reply-To: <20170425223301.23733-1-lionel.g.landwerlin@intel.com>

From: Robert Bragg <robert@sixbynine.org>

When measuring that rc6 doesn't happen, we need to do so after opening
the OA stream.
