You will also need to cover "ranges" that will describe the BARs
for the PCI
devices.
Good point.
Yes, very good point!
Could you please clarify how to recognize whether it is a PCI
device as long as PCI support is not merged? Or just to find any
device nodes

grant/foreign mappings instead of wasting real RAM pages from
the domain memory for establishing these mappings.
