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

- // Bit 24: Core ID Bit 25: Core Pair ID Bit 26-27: Reserved Bit 28-30: Socket ID Bit 31: Reserved\r
- // 4 Sockets and 4 Cores per Socket.\r
- // So possible LAPIC IDs 00, 01, 02, 03, 10, 11, 12, 13, 20, 21, 22, 23, 30, 31, 32, 33\r

- // BSP needs to be first entry in table. Check before boot. If BSP non zero need to rotate the entries.\r
- // Suppore BSP is LAPIC ID xy. Rotate the table by using formula [x + (y * 4)]\r
- // So if BSP LAPIC ID is 21 then table rotated 6 times.\r
- // End of Reference Text.\r
- // Thurley is supposed to be 2 sockets, 4 cores, and hyperthreading available per each core.\r
- // 2 (sockets) x 4 (cores) = 8 (processors non-HT), 8 (processors non-HT) x 2 (HT/proc) = 16 (HT procs)\r
- // Rhyme & reason of the ordering below. This is a best guess ordering for now,\r
- // Thurley EPS may give better info on LAPIC numbers.\r
- // Ordering was established to help dissipate heat across two sockets evenly.\r
- // Since logical processor number only has to be unique, I followed\r
- // a similar approach to high end servers and have the first digit of the LAPIC\r
