So how exactly does nonblocking commit work for you? Please run the igt
validation suit on your new driver, a bunch of collabora engineers are
working hard to make it run on non-intel drivers too. Ping Tomeu and
Robert Foss for more info on this please.
Lucky for you I'm working on generic nonblocking support in the atomic
helpers, patches are on the mailing list.
