I think in case of PIC mode, interrupts Yes it's probably virtual wire. For real PIC mode we would need really old systems without APIC. > can be delivered to cpu0 only. In virt wire mode, one can program IOAPIC > to deliver interrupt to any of the cpus and that's what we have been The code doesn't try to program anything specific, it just restores the state that was left over originally by the BIOS. -Andi - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to [email protected] More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
