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 tristate "Output ACPI APEI/GHES BIOS detected errors via EDAC"
57 depends on ACPI_APEI_GHES
60 Not all machines support hardware-driven error report. Some of those
61 provide a BIOS-driven error report mechanism via ACPI, using the
62 APEI/GHES driver. By enabling this option, the error reports provided
63 by GHES are sent to userspace via the EDAC API.
65 When this option is enabled, it will disable the hardware-driven
66 mechanisms, if a GHES BIOS is detected, entering into the
67 "Firmware First" mode.
69 It should be noticed that keeping both GHES and a hardware-driven
70 error mechanism won't work well, as BIOS will race with OS, while
71 reading the error registers. So, if you want to not use "Firmware
72 first" GHES error mechanism, you should disable GHES either at
73 compilation time or by passing "ghes.disable=1" Kernel parameter
79 tristate "AMD64 (Opteron, Athlon64)"
80 depends on AMD_NB && EDAC_DECODE_MCE
84 Support for error detection and correction of DRAM ECC errors on

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