| 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. | |

| 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. | |
