I'm not sure what the point of your questions is. Do you want to do something concrete or are you just interested in random buzzwords? Anyways as far as I know Linux supports the IO APICs implemented in all x86 chipsets fully. That is it doesn't use every possible feature they have, but I'm not aware of any particular limitation caused by Linux not supporting some IO APIC feature. The reason for the local x/APIC was that the original non x APIC did not support more than 8 logical CPUs being active in the system. Presumably IO xAPIC refers to the IO APIC without this limitation too. -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/
