help
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.

help
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.
config ACPI_APEI_PCIEAER

help
PCIe AER errors may be reported via APEI firmware first mode.
Turn on this option to enable the corresponding support.

help
Memory errors may be reported via APEI firmware first mode.
Turn on this option to enable the memory recovering support.

help
EINJ provides a hardware error injection mechanism, it is
mainly used for debugging and testing the other parts of
APEI and some other RAS features.

help
Support for CXL protocol Error INJection through debugfs/cxl.
Availability and which errors are supported is dependent on
the host platform. Look to ACPI v6.5 section 18.6.4 and kernel
EINJ documentation for more information.
If unsure say 'n'
config ACPI_APEI_ERST_DEBUG

help
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.
