Oh that's pretty awesome.

I know that when mmacy starting hacking on this his original goal was to 
get support for AMDGPU working for some boards he had on hand.

The testing I've done is only on Intel i915 chips you'd find on Skylake 
or Kabylake systems.  Since the rig you link to seems to use NVidia 
GPU's I'd guess that this port wouldn't change anything. Although 
hopefully with the refactored lkpi layer it'll be easier to port over 
Linux GPU code for Nvidia down the road.

Cheers,
