| 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. | |

| // 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. | |
