:$somewhere (On PCI domain 0)
Cool, so we don't have an chicken-and-egg issue.
If we can

Hi,
Since we will not use all 256 buses of an extra PCI domain,
I think this space will allow us to support more PCI domains.
Depends on the use case I guess. If you just need many pcie devices
this probably doesn't help. If you want

I would skip support for IO based configurati
