Do you have any plan to support this GPU?  Is it possible that it'll just work
if one adds the GPU to the igd_devices list in
usr.sbin/bhyve/amd64/pci_gvt-d.c?

> bhyve doesn't support resizable BAR. IIRC, it can cause issues when activated for an passthrough device.

AFAIU, it's the kernel itself that needs to support resizeable BARs.  bhyve
just uses /dev/pci to map them, is that right?
