ACPI, APEI, APEI supporting infrastructure APEI stands for ACPI Platform Error Interface, which allows to report errors (for example from the chipset) to the operating system. This improves NMI handling especially. In addition it supports error serialization and error injection. For more information about APEI, please refer to ACPI Specification version 4.0, chapter 17. This patch provides some common functions used by more than one APEI tables, mainly framework of interpreter for EINJ and ERST. A machine readable language is defined for EINJ and ERST for OS to execute, and so to drive the firmware to fulfill the corresponding functions. The machine language for EINJ and ERST is compatible, so a common framework is defined for them.

ACPI, APEI, Generic Hardware Error Source memory error support Generic Hardware Error Source provides a way to report platform hardware errors (such as that from chipset). It works in so called "Firmware First" mode, that is, hardware errors are reported to firmware firstly, then reported to Linux by firmware. This way, some non-standard hardware error registers or non-standard hardware link can be checked by firmware to produce more valuable hardware error information for Linux. Now, only SCI notification type and memory errors are supported. More notification type and hardware error type will be added later. These memory errors are reported to user space through /dev/mcelog via faking a corrected Machine Check, so that the error memory page can be offlined by /sbin/mcelog if the error count for one page is beyond the threshold. On some machines, Machine Check can not report physical address for some corrected memory errors, but GHES can do that. So this simplified GHES is implemented firstly.

ACPI, APEI, EINJ support EINJ provides a hardware error injection mechanism, this is useful for debugging and testing of other APEI and RAS features.

ACPI, APEI, Error Record Serialization Table (ERST) support ERST is a way provided by APEI to save and retrieve hardware error record to and from some simple persistent storage (such as flash). The Linux kernel support implementation is quite simple and workable in NMI context. So it can be used to save hardware error record into flash in hardware error exception or NMI handler, where other more complex persistent storage such as disk is not usable. After saving hardware error records via ERST in hardware error exception or NMI handler, the error records can be retrieved and logged into disk or network after a clean reboot. For more information about ERST, please refer to ACPI Specification version 4.0, section 17.4. This patch incorporate fixes from Jin Dongming.
