Subject: [PATCH 02/12] drm/i915: implement WaDisableL3CacheAging on VLV
Date: Tue,  2 Oct 2012 17:43:36 -0500	[thread overview]
Message-ID: <1349217826-2538-3-git-send-email-jbarnes@virtuousgeek.org> (raw)
In-Reply-To: <1349217826-2538-1-git-send-email-jbarnes@virtuousgeek.org>

Needs to be set on every context restore as well, so set it as part of
the initial state so we can save/restore it.
