From: Ville Syrjälä <[email protected]> Declare which FBC instances are present via a fbc_mask in device info. For the moment there is just the one.
TODO: Need to figure out how to expose multiple FBC instances in debugs. Just different file names, or move the files under some subdirectory (per-crtc maybe), or something else? This will need igt changes as well.
