Needs serious work on the plane scaling igt (it's atm all broken, and
doesn't test any atomic interactions).

Then this needs serious work on the nv12 plane igts (which don't yet
exist).

Then this probably needs pile more igts to test interactions between
everything (e.g. rotation, ...).

In short: This needs itgs. Lots of them :-)

Before those exist, and before we've tracked down the bug in the existing
code you're building on it imo makes no sense to start reviewing these
here.

Thanks, Daniel
