ACPI HEST table.
HEST feature starts from ACPI 4.0. HEST is one of four kinds of tables of ACPI Platform Error Interfaces (APEI). In Windows world, APEI is called Windows Hardware Error Architecture (WHEA). APEI consists of four separate tables: 1. Error Record Serialization Table (ERST) 2. BOOT Error Record Table (BERT) 3. Hardware Error Source Table (HEST) 4. Error Injection Table (EINJ) All these 4 tables have the same header as FADT, MADT, etc. They are pointed by RSDP. For the HEST, it contains the error source. The types of them are defined as type description 1. Machine Check Exception (MCE) 2. Corrected Machine Check (CMC) 3. NMI Error 6. PCI Express Root Port AER 7. PCI Express Device AER 8. PCI Express Bridge AER 9. Generic Hardware Error Source Error source types 3, 4, and 5 are reserved for legacy reasons and must not be used. Currently AMD board only provide part of "Machine Check Exception (MCE)" & Corrected Machine Check (CMC)". we need to provide the header of each error source. Other types of Error Sources is in TODO list. Only persimmon is tested. Linux can add HEST feature. The dmesg says, ACPI: HEST 0000000066fe5010 00198 (v03 CORE COREBOOT 00000000 CORE 00000000) ...... HEST: Table parsing has been initialized. No more message is got. Windows can boot with this patch. Havent found a way to test it.
