  13 Abstract:
  14
  15   This file contains a structure definition for the ACPI 2.0 Multiple APIC
  16   Description Table (MADT).  Any changes to the MADT table require updating the
  17   respective structure count in Madt.h and then adding the structure to the
  18   MADT defined in this file.  The table layout is defined in Madt.h and the
  19   table contents are defined in Acpi3_0.h and Madt.h.

  73   // Thurley is supposed to be 2 sockets, 4 cores, and hyperthreading available per each core.
