bool "EDAC (Error Detection And Correction) reporting"
depends on HAS_IOMEM
depends on X86 || PPC || TILE || ARM || EDAC_SUPPORT
help
EDAC is designed to report errors in the core system.
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'.
If this code is reporting problems on your system, please
see the EDAC project web pages for more information at:
and:
There is also a mailing list for the EDAC project, which can
be found via the sourceforge page.
if EDAC
config EDAC_LEGACY_SYSFS
bool "EDAC legacy sysfs"
default y
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"
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.
config EDAC_DECODE_MCE
tristate "Decode MCEs in human-readable form (only on AMD for now)"
depends on CPU_SUP_AMD && X86_MCE_AMD
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_MCE_INJ
tristate "Simple MCE injection interface over /sysfs"
depends on EDAC_DECODE_MCE

help
This is a simple interface to inject MCEs over /sysfs and test
the MCE decoding code in EDAC.
This is currently AMD-only.
config EDAC_MM_EDAC
tristate "Main Memory EDAC (Error Detection And Correction) reporting"
help
Some systems are able to detect and correct errors in main
memory. EDAC can report statistics on memory error
detection and correction (EDAC - or commonly referred to ECC
errors). EDAC will also try to decode where these errors
occurred so that a particular failing memory module can be
replaced. If unsure, select 'Y'.
config EDAC_GHES
bool "Output ACPI APEI/GHES BIOS detected errors via EDAC"
depends on ACPI_APEI_GHES && (EDAC_MM_EDAC=y)
default 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'.

config EDAC_AMD64_ERROR_INJECTION
bool "Sysfs HW Error injection facilities"
depends on EDAC_AMD64
help
Recent Opterons (Family 10h and later) 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.
