Hi all,
My Ryzen stuff finally arrived, so I can help get GPU Passthrough working.
My CPU is the 1800X and my motherboard is the Asus Prime X370-Pro.

I'm on kernel 4.10.1.

The IOMMU groups are indeed bad:

As you can see, the graphics cards are grouped together.

Alex, I've linked lspci -xxx -vvv and dmesg below. Please let me know if
you see anything, or need any more information.

lspci: https://paste.pound-python.org/show/iOgBaLrDZEGefuJjZlgy/

dmesg: https://paste.pound-python.org/show/3eevItiXBhgCjwDXVxQX/


Thanks,
Sarnex
