6 config EDAC_ATOMIC_SCRUB
13 bool "EDAC (Error Detection And Correction) reporting"
14 depends on HAS_IOMEM && EDAC_SUPPORT
16 EDAC is designed to report errors in the core system.
17 These are low-level errors that are reported in the CPU or
18 supporting chipset or other subsystems:
19 memory errors, cache errors, PCI errors, thermal throttling, etc..
20 If unsure, select 'Y'.
22 If this code is reporting problems on your system, please
23 see the EDAC project web pages for more information at:
25 <http://bluesmoke.sourceforge.net/>
29 <http://buttersideup.com/edacwiki>
31 There is also a mailing list for the EDAC project, which can
32 be found via the sourceforge page.
36 config EDAC_LEGACY_SYSFS
37 bool "EDAC legacy sysfs"
40 Enable the compatibility sysfs nodes.
41 Use 'Y' if your edac utilities aren't ported to work with the newer
47 This turns on debugging information for the entire EDAC subsystem.
48 You do so by inserting edac_module with "edac_debug_level=x." Valid
49 levels are 0-4 (from low to high) and by default it is set to 2.
50 Usually you should select 'N' here.
52 config EDAC_DECODE_MCE
53 tristate "Decode MCEs in human-readable form (only on AMD for now)"
54 depends on CPU_SUP_AMD && X86_MCE_AMD
57 Enable this option if you want to decode Machine Check Exceptions
58 occurring on your machine in human-readable form.
60 You should definitely say Y here in case you want to decode MCEs
61 which occur really early upon boot, before the module infrastructure
65 tristate "Main Memory EDAC (Error Detection And Correction) reporting"
68 Some systems are able to detect and correct errors in main
69 memory. EDAC can report statistics on memory error
70 detection and correction (EDAC - or commonly referred to ECC
71 errors). EDAC will also try to decode where these errors
72 occurred so that a particular failing memory module can be
73 replaced. If unsure, select 'Y'.
76 bool "Output ACPI APEI/GHES BIOS detected errors via EDAC"
77 depends on ACPI_APEI_GHES && (EDAC_MM_EDAC=y)
80 Not all machines support hardware-driven error report. Some of those
81 provide a BIOS-driven error report mechanism via ACPI, using the
82 APEI/GHES driver. By enabling this option, the error reports provided
83 by GHES are sent to userspace via the EDAC API.
85 When this option is enabled, it will disable the hardware-driven
86 mechanisms, if a GHES BIOS is detected, entering into the
87 "Firmware First" mode.
89 It should be noticed that keeping both GHES and a hardware-driven
90 error mechanism won't work well, as BIOS will race with OS, while
91 reading the error registers. So, if you want to not use "Firmware
92 first" GHES error mechanism, you should disable GHES either at
93 compilation time or by passing "ghes.disable=1" Kernel parameter

105 config EDAC_AMD64_ERROR_INJECTION
106 bool "Sysfs HW Error injection facilities"
107 depends on EDAC_AMD64
109 Recent Opterons (Family 10h and later) provide for Memory Error
110 Injection into the ECC detection circuits. The amd64_edac module
111 allows the operator/user to inject Uncorrectable and Correctable
114 When enabled, in each of the respective memory controller directories
115 (/sys/devices/system/edac/mc/mcX), there are 3 input files:
117 - inject_section (0..3, 16-byte section of 64-byte cacheline),
118 - inject_word (0..8, 16-bit word of 16-byte section),
119 - inject_ecc_vector (hex ecc vector: select bits of inject word)
121 In addition, there are two control files, inject_read and inject_write,
122 which trigger the DRAM ECC Read and Write respectively.
