| help | |
| EDAC is a subsystem along with hardware-specific drivers designed to | |
| report hardware errors. These are low-level errors that are reported | |
| in the CPU or supporting chipset or other subsystems: | |
| memory errors, cache errors, PCI errors, thermal throttling, etc.. | |
| If unsure, select 'Y'. | |

| help | |
| Not all machines support hardware-driven error report. Some of those | |
| provide a BIOS-driven error report mechanism via ACPI, using the | |
| APEI/GHES driver. By enabling this option, the error reports provided | |
| by GHES are sent to userspace via the EDAC API. | |
| When this option is enabled, it will disable the hardware-driven | |
| mechanisms, if a GHES BIOS is detected, entering into the | |
| "Firmware First" mode. | |
| It should be noticed that keeping both GHES and a hardware-driven | |
| error mechanism won't work well, as BIOS will race with OS, while | |
| reading the error registers. So, if you want to not use "Firmware | |
| first" GHES error mechanism, you should disable GHES either at | |
| compilation time or by passing "ghes.disable=1" Kernel parameter | |
| at boot time. | |
| In doubt, say 'Y'. | |
