Abstract
Following a restart or a reboot of a system that includes a multi-core processor, the multi-core processor may assign each active and eligible core a unique advanced programmable interrupt controller (APIC) identifier (ID). Initialization logic may detect a state of each of the plurality of processing cores as active or inactive. The initialization logic may detect an attribute of each of the plurality of processing cores as eligible to be assigned an APIC ID or as ineligible to be assigned the APIC ID.
