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 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. 63 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. 67 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 73 at boot time. 74 75 In doubt, say 'Y'. 76 77config EDAC_AMD64 78 tristate "AMD64 (Opteron, Athlon64)" 79 depends on AMD_NB && EDAC_DECODE_MCE 80 help 81 Support for error detection and correction of DRAM ECC errors on 82 the AMD64 families (>= K8) of memory controllers. 83 84config EDAC_AMD64_ERROR_INJECTION 85 bool "Sysfs HW Error injection facilities" 86 depends on EDAC_AMD64 87 help 88 Recent Opterons (Family 10h and later) provide for Memory Error 89 Injection into the ECC detection circuits.
