The new Intel ACPI implementation now merged into 2.5 should support this. Of course it may still not work on your particular BIOS. > If it's possible, is it also meaningful to do this on UP? Using the IO-APIC makes a lot of sense, because it is a much more efficient interface to the interrupt controller. -Andi ^ permalink raw reply [flat|nested] 3+ messages in thread
