H A Dcpu-hotplug-spec.rst12 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
