No subject

19.[0123] and other processor devices all live on PCI bus 0? Is that bus
somewhat related to the buses attached via ncHT? IIRC I once saw a
machine where 18.[0123] was alone on bus 0 and all other PCI devices
were on separate buses.

Taking the "everything is PCI" model, how would I specify the virtual
PCI buses attached via ncHT? Are they children (secondary buses) of 18.0
which would act like a PCI-to-PCI bridge?

Agreed.

They need a way to specify settings for any given PCI device. Since most
modern machines have multiple PCI devices with the same vendor/device
ID, we have to be able to identify devices based on their logical path.
For that, we have to model the logical PCI bus/device/tree reasonably
well. I'm trying to do that, but no model seems to fit.
