| 6 | APEI allows to report errors (for example from the chipset) |
| 7 | to the operating system. This improves NMI handling |
| 8 | especially. In addition it supports error serialization and |
| 9 | error injection. |

| 15 | help |
| 16 | Generic Hardware Error Source provides a way to report |
| 17 | platform hardware errors (such as that from chipset). It |
| 18 | works in so called "Firmware First" mode, that is, hardware |
| 19 | errors are reported to firmware firstly, then reported to |
| 20 | Linux by firmware. This way, some non-standard hardware |
| 21 | error registers or non-standard hardware link can be checked |
| 22 | by firmware to produce more valuable hardware error |
| 23 | information for Linux. |
