6.2.10 _MAT (Multiple APIC Table Entry)
This optional object evaluates to a buffer returning data in the format of a series of Multiple APIC
Description Table (MADT) APIC Structure entries. This object can appear under an I/O APIC or
processor object definition as processors may contain Local APICs. Specific types of MADT entries
are meaningful to (in other words, is processed by) OSPM when returned via the evaluation of this
object as described below. Other entry types returned by the evaluation of _MAT are ignored by
OSPM.
When _MAT appears under a Processor object, OSPM processes Local APIC (Section 5.2.12.2,
“Processor Local APIC Structure”), Local SAPIC Structure (Section 5.2.12.10, “Local SAPIC
Structure”), local APIC NMI (Section 5.2.12.7, “Local APIC NMI Structure”), Processor Local
x2APIC Structure (Section 5.2.12.12 Processor Local x2APIC Structure), Local x2APIC NMI
(Section 5.2.12.13 Local x2APIC NMI Structure), and GICC Structure (Section 5.2.12.14 GICC
Structure) entries returned from the object’s evaluation. Other entry types are ignored by OSPM.
OSPM uses the ACPI processor ID in the entries returned from the object’s evaluation to identify the
