Aside, intel_check_sprite_plane is a giant function, some extraction of sub-parts and helpers (like computing can_scale and stuff) would be good. A lot of the big local variable list could e.g. be moved into intel_plane_state (like the dynamic can_scale) and then we just need to pass around the state pointer to the various subfunctions. > Reviewed-by: Ville Syrjälä <ville.syrjala@linux.intel.com> Queued for -next, thanks for the patch. -Daniel > > Ps.

And some of it should be split up into platform specific checks since not all platforms have the same restrictions. I think what's there is generally valid for ILK-IVB but may not be really valid for others.

There is a mplayer video failure reported with xv. This is because there is a request to do both plane scaling and colorkey. Because skl hw doesn't support plane scaling and colorkey at the same time, request is failed which is expected behavior. To make xv operate, this patch allows colorkey continue to work without using scaler. Then behavior would be similar to platforms without plane scaler support.
