Local APIC

The synthetic interrupt controller (SynIC) is a superset of a local Advanced Programmable Interrupt Controller (APIC). The interface to this APIC is given by a set of 32-bit memory-mapped registers. This local APIC (including the behavior of the memory-mapped registers) is generally compatible with the local APIC on P4 and Xeon systems as described in Intel's documentation.

The following sections describe the local APIC:
