Re: /proc/bus/pci and domains

Hi Greg!

I have no idea, it sounds like a PPC specific thing, not anything the
PCI core does, right?  So I'll add the ppc list to the cc: and ask if
anyone there has any ideas?

Unfortunately, this is not PPC specific at all -- proc_attach_device()
calls pci_proc_domain(bus), which is an arch-specific hook turning on
the weird behavior I described. This hook can return non-zero even on
x86 if there are buses outside domain 0.

I think that the hook itself is correct, it only should trigger more
consistent behavior of the generic code :)

Would it be acceptable for the PPC folks to modify the code to add
domain numbers to the device numbers in /proc/bus/pci/devices in the
same format as the bus directories already have?

If so, I will cook up a patch.

				Have a nice fortnight
