Hi, Rob!

Nice work!

I can do some testing later this week. In our xorg driver / DDX, we have
a special "rendercheck" mode that disables the migration heuristics and
always enable hardware acceleration. Although unfortunately I don't
think there are any solid fill hooks.
I'll also try to review the patches as soon as I have some time.

some quick questions:
Did you run the newly enabled accelerated operations through "rendercheck"?
What does the performance look like on the "modesetting" driver with
shadow framebuffer enabled, compared to freedreno with acceleration enabled?

Thanks,
Thomas
