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'. 21 22 The mailing list for the EDAC project is linux-edac@vger.kernel.org. 23 24if EDAC 25 26config EDAC_LEGACY_SYSFS 27 bool "EDAC legacy sysfs" 28 default y 29 help 30 Enable the compatibility sysfs nodes. 31 Use 'Y' if your edac utilities aren't ported to work with the newer 32 structures. 33 34config EDAC_DEBUG 35 bool "Debugging" 36 select DEBUG_FS 37 help 38 This turns on debugging information for the entire EDAC subsystem. 39 You do so by inserting edac_module with "edac_debug_level=x."

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. 64 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. 68 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 74 at boot time. 75 76 In doubt, say 'Y'. 77 78config EDAC_AMD64 79 tristate "AMD64 (Opteron, Athlon64)" 80 depends on AMD_NB && EDAC_DECODE_MCE 81 help 82 Support for error detection and correction of DRAM ECC errors on 83 the AMD64 families (>= K8) of memory controllers. 84 85 When EDAC_DEBUG is enabled, hardware error injection facilities 86 through sysfs are available: 87 88 AMD CPUs up to and excluding family 0x17 provide for Memory 89 Error Injection into the ECC detection circuits.
