Subject: [PATCH 07/23] intel-gtt: generic intel_fake_agp_fetch_size
Date: Wed,  1 Sep 2010 22:29:54 +0200	[thread overview]
Message-ID: <1283373010-1314-8-git-send-email-daniel.vetter@ffwll.ch> (raw)
In-Reply-To: <1283373010-1314-1-git-send-email-daniel.vetter@ffwll.ch>

This uses the new mappable gtt size detection from the previous patch.
