Hi,
I've just flashed the most recent coreboot with Linux payload on my KGPE-D16. However, there're some problems with GPU.
I have an RX550, but it seems that amdgpu has bug with AMD-Vi which I found in some mailing list ( https://lists.freedesktop.org/archives/amd-gfx/2017-March/006490.html), and it still doesn't work after I use amd_iommu=fullflush, and using amd_iommu=off will make the machine not able to find USB devices.
And I have a GTX750, but xf86-video-nouveau doesn't work on this Maxwell card.
