ioapic is an I/O Advanced Programmable
Interrupt Controller (APIC). It provides interrupt management for systems
with multiple I/O subsystems and can distribute interrupts across multiple
processors.
ioapic is based on Intel's 82093AA I/O
Advanced Programmable Interrupt Controller (I/O APIC) specification.
The ioapic driver first appeared in
OpenBSD 3.5.
The ioapic driver was written by
Bill Sommerfield.
