From: Chris Wilson Date: Sun, 16 Dec 2012 12:43:36 +0000 (+0000) Subject: drm/i915: Access to snooped system memory through the GTT is incoherent X-Git-Tag: v3.9-rc1~83^2~40^2~18 X-Git-Url: http://git.openpandora.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=eb119bd612906519cacef2536a9a524c2da5f7fb;p=pandora-kernel.git drm/i915: Access to snooped system memory through the GTT is incoherent We ignore all the user requests to handle flushing to the GTT domain if the user requests such on a snoopable bo, and as such access through the GTT to such pages remains incoherent. The specs even warn that such behaviour is undefined - a strong reason never to do so. Signed-off-by: Chris Wilson Signed-off-by: Daniel Vetter --- Reading git-diff-tree failed
