Abstract: A technique to enable efficient interrupt communication within a computer system. In one embodiment, an advanced programmable interrupt controller (APIC) is interfaced via a set of bits within an APIC interface register using various interface instructions or operations, without using memory-mapped input/output (MMIO).
