443 | * at the FADT length because the version number essentially tells |
444 | * us nothing because of many BIOS bugs where the version does not |
445 | * match the expected length. In other words, the length of the |
446 | * FADT is the bottom line as to what the version really is. |
447 | * |
448 | * NOTE: There is no officialy released V2 of the FADT. This |
449 | * version was used only for prototyping and testing during the |
450 | * 32-bit to 64-bit transition. V3 was the first official 64-bit |
451 | * version of the FADT. |
452 | * |
453 | * Update this list of defines when a new version of the FADT is |
454 | * added to the ACPI specification. Note that the FADT version is |
455 | * only incremented when new fields are appended to the existing |
456 | * version. Therefore, the FADT version is competely independent |
457 | * from the version of the ACPI specification where it is |
458 | * defined. |
459 | * |
460 | * For reference, the various FADT lengths are as follows: |
461 | * FADT V1 size: 0x074 ACPI 1.0 |
462 | * FADT V3 size: 0x0F4 ACPI 2.0 |
463 | * FADT V4 size: 0x100 ACPI 3.0 and ACPI 4.0 |
464 | * FADT V5 size: 0x10C ACPI 5.0 |
465 | * FADT V6 size: 0x114 ACPI 6.0 |
