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.

This option should be enabled if the system supports
|
||
|
|
firmware first handling of SEA (Synchronous External Abort).
|
||
|
|
SEA happens with certain faults of data abort or instruction
|
||
|
|
abort synchronous exceptions on ARMv8 systems. If a system
|
||
|
|
supports firmware first handling of SEA, the platform analyzes
|
||
|
|
and handles hardware error notifications from SEA, and it may then
|
||
|
|
form a HW error record for the OS to parse and handle. This
|
||
|
|
option allows the OS to look for such hardware error record, and
|
||
|
|
take appropriate action.

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.
