6 config EDAC_ATOMIC_SCRUB
13 tristate "EDAC (Error Detection And Correction) reporting"
14 depends on HAS_IOMEM && EDAC_SUPPORT && RAS
16 EDAC is a subsystem along with hardware-specific drivers designed to
17 report hardware errors. These are low-level errors that are reported
18 in the CPU or supporting chipset or other subsystems:
19 memory errors, cache errors, PCI errors, thermal throttling, etc..
20 If unsure, select 'Y'.
26 config EDAC_LEGACY_SYSFS
27 bool "EDAC legacy sysfs"
30 Enable the compatibility sysfs nodes.
31 Use 'Y' if your edac utilities aren't ported to work with the newer
38 This turns on debugging information for the entire EDAC subsystem.
39 You do so by inserting edac_module with "edac_debug_level=x." Valid
40 levels are 0-4 (from low to high) and by default it is set to 2.
41 Usually you should select 'N' here.
43 config EDAC_DECODE_MCE
44 tristate "Decode MCEs in human-readable form (only on AMD for now)"
45 depends on CPU_SUP_AMD && X86_MCE_AMD
48 Enable this option if you want to decode Machine Check Exceptions
49 occurring on your machine in human-readable form.
51 You should definitely say Y here in case you want to decode MCEs
52 which occur really early upon boot, before the module infrastructure
56 bool "Output ACPI APEI/GHES BIOS detected errors via EDAC"
57 depends on ACPI_APEI_GHES && (EDAC=y)
59 Not all machines support hardware-driven error report. Some of those
60 provide a BIOS-driven error report mechanism via ACPI, using the
61 APEI/GHES driver. By enabling this option, the error reports provided
62 by GHES are sent to userspace via the EDAC API.
64 When this option is enabled, it will disable the hardware-driven
65 mechanisms, if a GHES BIOS is detected, entering into the
66 "Firmware First" mode.
68 It should be noticed that keeping both GHES and a hardware-driven
69 error mechanism won't work well, as BIOS will race with OS, while
70 reading the error registers. So, if you want to not use "Firmware
71 first" GHES error mechanism, you should disable GHES either at
72 compilation time or by passing "ghes.disable=1" Kernel parameter

90 allows the operator/user to inject Uncorrectable and Correctable
93 When enabled, in each of the respective memory controller directories
94 (/sys/devices/system/edac/mc/mcX), there are 3 input files:
