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:)

Hi,

 

  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
