tristate "EDAC (Error Detection And Correction) reporting"
depends on HAS_IOMEM && EDAC_SUPPORT && RAS
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'.
The mailing list for the EDAC project is [email protected].

config EDAC_LEGACY_SYSFS

help
Enable the compatibility sysfs nodes.
Use 'Y' if your edac utilities aren't ported to work with the newer
structures.
config EDAC_DEBUG
bool "Debugging"
select DEBUG_FS
help
This turns on debugging information for the entire EDAC subsystem.
You do so by inserting edac_module with "edac_debug_level=x." Valid
levels are 0-4 (from low to high) and by default it is set to 2.
Usually you should select 'N' here.

default y
help
Enable this option if you want to decode Machine Check Exceptions
occurring on your machine in human-readable form.
You should definitely say Y here in case you want to decode MCEs
which occur really early upon boot, before the module infrastructure
has been initialized.
config EDAC_GHES
tristate "Output ACPI APEI/GHES BIOS detected errors via EDAC"
depends on ACPI_APEI_GHES
select UEFI_CPER
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'.

help
Support for error detection and correction of DRAM ECC errors on
the AMD64 families (>= K8) of memory controllers.
When EDAC_DEBUG is enabled, hardware error injection facilities
through sysfs are available:
AMD CPUs up to and excluding family 0x17 provide for Memory
Error Injection into the ECC detection circuits. The amd64_edac
module allows the operator/user to inject Uncorrectable and
Correctable errors into DRAM.
When enabled, in each of the respective memory controller directories
(/sys/devices/system/edac/mc/mcX), there are 3 input files:
- inject_section (0..3, 16-byte section of 64-byte cacheline),
- inject_word (0..8, 16-bit word of 16-byte section),
- inject_ecc_vector (hex ecc vector: select bits of inject word)
In addition, there are two control files, inject_read and inject_write,
which trigger the DRAM ECC Read and Write respectively.
