Detailed Description

The MPS config table I/O APIC entry.

Identifies an I/O APIC (Advanced Programmable Interrupt Controller), required on all multiprocessor systems and very useful on all uniprocessor systems.

There may be one or more IOAPICs in a system, each handling a set of physical interrupts.

The IOAPIC(s) arbitrate most physical interrupt (IRQ) lines connected on the motherboard of a system and dispatch the interrupts to the CPUs via their LAPICs.
