Module Name:
Madt3.0.c
Abstract:
This file contains a structure definition for the ACPI 2.0 Multiple APIC
Description Table (MADT). Any changes to the MADT table require updating the
respective structure count in Madt.h and then adding the structure to the
MADT defined in this file. The table layout is defined in Madt.h and the
table contents are defined in Acpi3_0.h and Madt.h.

// Correct processor order, Primary threads first then Hyper threads
// And correct APIC-ids
// This text below is included as a reference until Thurley is 100%:
// According to EDS the Local APIC ID is determined based of a bit structure
// Bit 24: Core ID Bit 25: Core Pair ID Bit 26-27: Reserved Bit 28-30: Socket ID Bit 31: Reserved
// 4 Sockets and 4 Cores per Socket.
// So possible LAPIC IDs 00, 01, 02, 03, 10, 11, 12, 13, 20, 21, 22, 23, 30, 31, 32, 33
// Static Entries 00, 10, 20, 30, 01, 11, 21, 31, 02, 12, 22, 32, 03, 13, 23, 33
// BSP needs to be first entry in table. Check before boot. If BSP non zero need to rotate the entries.
// Suppore BSP is LAPIC ID xy. Rotate the table by using formula [x + (y * 4)]
// So if BSP LAPIC ID is 21 then table rotated 6 times.
// End of Reference Text.
// Thurley is supposed to be 2 sockets, 4 cores, and hyperthreading available per each core.
// 2 (sockets) x 4 (cores) = 8 (processors non-HT), 8 (processors non-HT) x 2 (HT/proc) = 16 (HT procs)
// Rhyme & reason of the ordering below. This is a best guess ordering for now,
// Thurley EPS may give better info on LAPIC numbers.
// Ordering was established to help dissipate heat across two sockets evenly.
// Since logical processor number only has to be unique, I followed
// a similar approach to high end servers and have the first digit of the LAPIC
// id the socket number.
