X2APIC (Advanced Programmable Interrupt Controller)
Based on Intel's Hyper-Threading architecture, each logical processor (thread) is
assigned 256 APIC IDs (APIDs) in 8-bit bandwidth. When this feature is set to En-
able, the APIC ID will be expanded (X2) from 8 bits to 16 bits to provide 512 APIDs
to each thread to enhance CPU performance. The options are
Disable
and Enable.
