Side note: I've looked at "fixing" xf86-video-amdgpu and so far I'm at
~25 patches. Admittedly it includes some related fixes/cleanups.
At some point we want to address the other KMS ddx - armsoc (ahem),
ati, freedreno, intel, nouveau, omap, opentegra, vmwgfx, qxl and of
course modesetting ;-)
Regardless if some are superseded and/or barely used.
