drm/i915: Add an interface to dynamically change the cache level
[anholt v2: Don't forget that when going from cached to uncached, we haven't been tracking the write domain from the CPU perspective, since we haven't needed it for GPU coherency.] [ickle v3: We also need to make sure we relinquish any fences on older chipsets and clear the GTT for sane domain tracking.] Signed-off-by: Chris Wilson <chris@chris-wilson.co.uk> Signed-off-by: Eric Anholt <eric@anholt.net> Reviewed-by: Daniel Vetter <daniel.vetter@ffwll.ch>
