[Linux-ia64] iosapic_vector struct in Linux IA64?

[Linux-ia64] iosapic_vector struct in Linux IA64?

[White, Charles]

I am looking at an issue with Linux IA64, and the problem appears to be that
the ioapic_vector struct (iosapic.h) has only room for one
PCI/Bus/Dev/Func/Pin per PID entry... 

Being PCI devices can share interrupts, How do you handle that with only one
Entry?  Being even the PIN is part of the entry, you could not even Tie INTA
& INTC together.   

Is anyone looking into this issue?

We have started looking at this problem. Please let me know if you have done
anything on this. 

Thanks,
Asit

We are now implementing IRQ sharing code, but it's not complete.
