I think we need to either adjust the entire mode before handing it to userspace or if that's not possible we need to reject a modeset if the implicit vactive/vblank in the side-by-side framebuffer doesn't fit. On X even that shouldn't be an issue since the ddx could just duplicate this knowledge, more fun would be wayland or similar generic display servers. I'd opt to solve this when it's a real problem though and not before. -Daniel -- Daniel Vetter Software Engineer, Intel Corporation +41 (0) 79 365 57 48 - http://blog.ffwll.ch _______________________________________________ dri-devel mailing list dri-devel@lists.freedesktop.org http://lists.freedesktop.org/mailman/listinfo/dri-devel
