1 /** @file 2 This file describes the contents of the ACPI Multiple APIC Description 3 Table (MADT). Some additional ACPI values are defined in Acpi10.h and 4 Acpi20.h. 5 To make changes to the MADT, it is necessary to update the count for the 6 APIC structure being updated, and to modify table found in Madt.c. 7 8 Copyright (c) 2013-2015 Intel Corporation. 9 10 This program and the accompanying materials 11 are licensed and made available under the terms and conditions of the BSD License 12 which accompanies this distribution.
