7 title: Intel Local Advanced Programmable Interrupt Controller (LAPIC)
15 architecture design, with a local component (LAPIC) integrated
17 (lapic) receives interrupts from the processor's interrupt pins,
22 Many of the Intel's generic devices like hpet, ioapic, lapic have
32 const: intel,ce4100-lapic
47 Virtual Wire Mode - use lapic as virtual wire interrupt delivery mode.

| D | cpu-hotplug-spec.rst | 12 In ACPI each CPU needs an LAPIC object in the MADT table (5.2.11.5 in the
13 ACPI 3.0 specification). ACPI already has the concept of disabled LAPIC
14 objects by setting the Enabled bit in the LAPIC object to zero.
18 it should have its LAPIC Enabled bit set to 0. Linux will use the number
