  14           APEI allows to report errors (for example from the chipset)
  15           to the operating system. This improves NMI handling
  16           especially. In addition it supports error serialization and
  17           error injection.

  25         help
  26           Generic Hardware Error Source provides a way to report
  27           platform hardware errors (such as that from chipset). It
  28           works in so called "Firmware First" mode, that is, hardware
  29           errors are reported to firmware firstly, then reported to
  30           Linux by firmware. This way, some non-standard hardware
  31           error registers or non-standard hardware link can be checked
  32           by firmware to produce more valuable hardware error
  33           information for Linux.

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

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

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

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

  75         help
  76           ERST is a way provided by APEI to save and retrieve hardware
  77           error information to and from a persistent store. Enable this
  78           if you want to debugging and testing the ERST kernel support
  79           and firmware implementation.
