Um..., I'm confused more. If so, MADT doesn't say it. MADT says irq == 0 is pin == 2, this is one of reasons why linux is quite silent in check_timer(). And I can't see why it is working by pin == 2 for IOAPIC. If I can make time, I'll see what happens by pin == 2 and pin == 0 of IOAPIC in kvm.
You're right. The default routing is INTIN0, but qemu changes it to INTIN2 and tells kvm.
So INTIN0 is free for the 8259A output. -- error compiling committee.c: too many arguments to function -- To unsubscribe from this list: send the line "unsubscribe kvm" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
