- 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

- // 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.
