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 <chris@chris-wilson.co.uk> Signed-off-by: Daniel Vetter <daniel.vetter@ffwll.ch>
