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

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

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

  69           EINJ provides a hardware error injection mechanism, it is

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