Can you please explain a bit more background here? The previous proprosals
all were (at least to me) completely unclear about the what and why.

Isn't it enough to have a way for userland to tell which pciX is the parent
of pciY and maybe a function to get the list of all pci$N that don't have a
pci as parent?

What is the "domain" value used for inside the kernel?
