[vfio-users] vfio-pci with amd gpu in kernel 4.14.10+

[Peter Maloney]

Let's see an `lspci -knn` for each of those devices.

I'm using 4.14.x and have 3 AMD gpus, one for the host, and 2 for VMs,
and it works.

But I don't use the pci-stub.ids or the vfio-pic.ids kernel cmdline
syntax... I bind by pci address instead of vendor:device since they're
non-unique (using my script here
https://github.com/petermaloney/misc/blob/master/mkinitcpio-vfio-pci/hooks/vfio-pci).
PCI address can change on firmware updates or moving cards around, but
stays the same otherwise in my experience.
