SMP or single CPU?
If SMP, and io apci is enabled, you may only focus on mptable.c and irq-tables.c may only contain device that point to the peer roots bus.

Hi,
I didn't get an answer from the previous post so I'll just simplify a little bit. Can someone point me to where I can learn more about the magic that makes the pci_irq files?
Thanks, Dave:)

What happens if the pci irq mapping is a mess? I know you can use getpir with a good bios, but what if you don't have one? Is there a way to get the pci irq mapping without a standard bios? If you had to do it by hand could you explain how it should be done?
Thanks, Dave
