[Intel-gfx] [PATCH v2 2/4] drm/i915: Eliminate the RMW sprite colorkey management
ville.syrjala at linux.intel.com
ville.syrjala at linux.intel.com
Thu Mar 19 12:18:57 PDT 2015
From: Ville Syrjälä <ville.syrjala at linux.intel.com>
Store the colorkey in intel_plane and kill off all the RMW stuff
handling it.
This is just an intermediate step and eventually the colorkey needs to
be converted into some properties.
v2: Actually update the hardware state in the set_colorkey ioctl (Daniel)
