GHES (Generic Hardware Error Source) is used to process hardware error notification in firmware first mode. But because firmware first mode can be turned on but can not be turned off, it is unreasonable to unload the GHES module with firmware first mode turned on. To avoid confusion, this patch makes GHES can be enabled/disabled in configuration time, but not built as module and unloaded at run time.

APEI 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.

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.

PCIe AER errors may be reported via APEI firmware first mode.

ERST is a way provided by APEI to save and retrieve hardware

error information to and from a persistent store. Enable this
|
|
if you want to debugging and testing the ERST kernel support
|
|
and firmware implementation.
