└─>Output ACPI APEI/GHES BIOS detected errors via EDAC
In linux kernel since version 3.1 (release Date: 2011-10-24)  
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'.
