on the u200 and sei510 Tested-by: Jerome Brunet <jbru...@baylibre.com> I can't pretend to have a deep understanding of this subsystem, but as far as I can tell, there is nothing crazy in there. With the comments around the use of constants and defines fixed, you can add Reviewed-by: Jerome Brunet <jbru...@baylibre.com> As a possible future enhancement, it would be nice if you could trim the use of *_is_compatible() functions. I think it would make the code easier to follow and review. _______________________________________________ dri-devel mailing list dri-devel@lists.freedesktop.org https://lists.freedesktop.org/mailman/listinfo/dri-devel
