I took the work from https://patchwork.freedesktop.org/patch/27065/
and cleaned it up. I've been meaning to take what I'd done and post it.
Your question inspired me to take care of that and here is the result:

Also, Alastair Bridgewater pointed out to me that intel-gpu-tools has
some testing modes, but I only messed with it a little.

I have also played around with creating test patterns by extending
https://github.com/dvdhrm/docs/blob/master/drm-howto/modeset.c
but that is some very raw stuff and probably not particularly helpful
in the current state.
