Our hardware doesn't support mirroring (h or v). Well, unless you count h+v mirroring since that's 180 degree rotation :) Anyways IIRC the old video overlay (present on gen2-4) was the only plane to ever support mirroring on Intel hardware. With all other planes we're limited to 0 and 180 degree rotation. -- Ville Syrjälä Intel OTC _______________________________________________ dri-devel mailing list dri-devel@xxxxxxxxxxxxxxxxxxxxx http://lists.freedesktop.org/mailman/listinfo/dri-devel
