Subject: [igt-dev] [PATCH i-g-t v2 2/3] lib: Update surface state to set MOCS and coherency.
Date: Fri,  5 Oct 2018 20:04:35 +0200	[thread overview]
Message-ID: <1538762676-15259-3-git-send-email-tomasz.lis@intel.com> (raw)
In-Reply-To: <1538762676-15259-1-git-send-email-tomasz.lis@intel.com>

From: "Lis, Tomasz" <tomasz.lis@intel.com>

Having LLC cache enabled by MOCS is required to perform coherency tests.
Surface coherency type needs to be set as well for that test.
