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

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

| Support for decoding NVIDIA-specific CPER sections delivered via | |

| for the NVIDIA section GUID and logs error signatures, severity, | |
| socket, and diagnostic register address-value pairs. | |

| ACPI device NVDA2012 in their firmware tables. | |

| error information to and from a persistent store. Enable this | |
| if you want to debugging and testing the ERST kernel support | |
| and firmware implementation. |
