[Intel-gfx] [PATCH 4/5] drm/i915: add destination color key support
Jesse Barnes

Mon Nov 7 19:02:55 CET 2011
Add new ioctls for getting and setting the current destination color
key. This allows for simple overlay display control by matching a color
key value in the primary plane before blending the overlay on top.
