It was previously noted that Kconfig complained about unmet dependencies
when trying to configure skx_edac together with CONFIG_ACPI=n. First fix
for this checked for ACPI when doing
select ACPI_ADXL
but this required stub functions for the case where ACPI wasn't
selected. It also allowed building a driver that didn't actually work
for a system that has non-volatile DIMMs.
Arnd Bergmann pointed out that the right fix is to make EDAC_SKX
"depend on ACPI".

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'.

|
|
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'.
