Nah, this is something entirely different.
"async atomic commit" = doesn't block, but vblank synced for the entire
thing.
"async page flip" = also doesn't sync with vblank on top of async commit,
i.e. game benchmarking mode. Afaik intel hw only supports this on the
primary plane, and only through CS flips. Fairly similar to legacy cursor
updates, since those are allowed/should tear too.
We definitely don't want to set that flag. We might want to give it a more
descriptive name though, and some proper docs ;-)
Cheers, Daniel
