Provided by: apic
Class Hierarchy: conf-object → log-object → apic
Interfaces Implemented: log_object, event_poster, interrupt_cpu, apic_cpu, io_memory
Description: The APIC class implements the functionality of the local (on-chip) APIC that is part of the Intel Architecture and was first implemented in the Pentium processor. Each APIC instance is connected to an I/O-APIC through the APIC bus (multiple I/O-APIC systems are not supported). Reference: Intel Architecture Software Developer's Manual Volume 3.
