There's a bit a bikeshed going on with this, see:

https://lists.freedesktop.org/archives/dri-devel/2018-October/193214.html

I think would be good to add this as a new test-drm_format.c, so we have a
bit of proper code organization.

Also, I think just one kms_selftest wrapper for all of this would be good.

Can you pls reply in that other thread with ack (or comments) so we can
get some alignment about all the different efforts going on in parallel
right now?

Thanks, Daniel
