11 bool "EDAC (Error Detection And Correction) reporting"
13 depends on X86 || PPC || TILE || ARM || EDAC_SUPPORT
15 EDAC is designed to report errors in the core system.
16 These are low-level errors that are reported in the CPU or
17 supporting chipset or other subsystems:
18 memory errors, cache errors, PCI errors, thermal throttling, etc..
19 If unsure, select 'Y'.
21 If this code is reporting problems on your system, please
22 see the EDAC project web pages for more information at:
24 <http://bluesmoke.sourceforge.net/>
28 <http://buttersideup.com/edacwiki>
30 There is also a mailing list for the EDAC project, which can
31 be found via the sourceforge page.
35 config EDAC_LEGACY_SYSFS
36 bool "EDAC legacy sysfs"
39 Enable the compatibility sysfs nodes.
40 Use 'Y' if your edac utilities aren't ported to work with the newer
46 This turns on debugging information for the entire EDAC subsystem.
47 You do so by inserting edac_module with "edac_debug_level=x." Valid
48 levels are 0-4 (from low to high) and by default it is set to 2.
49 Usually you should select 'N' here.
51 config EDAC_DECODE_MCE
52 tristate "Decode MCEs in human-readable form (only on AMD for now)"
53 depends on CPU_SUP_AMD && X86_MCE_AMD
56 Enable this option if you want to decode Machine Check Exceptions
57 occurring on your machine in human-readable form.
59 You should definitely say Y here in case you want to decode MCEs
60 which occur really early upon boot, before the module infrastructure
64 tristate "Simple MCE injection interface"
65 depends on EDAC_DECODE_MCE && DEBUG_FS
68 This is a simple debugfs interface to inject MCEs and test different
69 aspects of the MCE handling code.
71 WARNING: Do not even assume this interface is staying stable!
74 tristate "Main Memory EDAC (Error Detection And Correction) reporting"
77 Some systems are able to detect and correct errors in main
78 memory. EDAC can report statistics on memory error
79 detection and correction (EDAC - or commonly referred to ECC
80 errors). EDAC will also try to decode where these errors
81 occurred so that a particular failing memory module can be
82 replaced. If unsure, select 'Y'.
85 bool "Output ACPI APEI/GHES BIOS detected errors via EDAC"
86 depends on ACPI_APEI_GHES && (EDAC_MM_EDAC=y)
89 Not all machines support hardware-driven error report. Some of those
90 provide a BIOS-driven error report mechanism via ACPI, using the
91 APEI/GHES driver. By enabling this option, the error reports provided
92 by GHES are sent to userspace via the EDAC API.
94 When this option is enabled, it will disable the hardware-driven
95 mechanisms, if a GHES BIOS is detected, entering into the
96 "Firmware First" mode.
98 It should be noticed that keeping both GHES and a hardware-driven
99 error mechanism won't work well, as BIOS will race with OS, while
100 reading the error registers. So, if you want to not use "Firmware
101 first" GHES error mechanism, you should disable GHES either at
102 compilation time or by passing "ghes.disable=1" Kernel parameter

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