Allowing qemu to use all ioapic interrupt pins will reduce interrupt
sharing on x86, which is a good thing, so I prefer the first option

Thanks for your support, I preper option #1,
Any suggestion for the mapping from BDF to irq.
In XEN both in IA64/IA32,
BIOS

With 24 free pins, that's fine. With 8 free pins, less so. We'll

I guess we need to increase the number of pins on x86 too.
If use this method, we can share same IA64 guest BIOS between
XEN/IA64 and KVM/IA64.
You can use this

x86 and ia64 have different DSDTs, so I don't see the need for dynamic
generation. The x86 DSDT can return different routing tables
depending
on whether one or two ioapics are present (this can be detected at
runtime).
Okay, use fixed DSDT
