| 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. |
