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. 84 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. 88 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 94 at boot time. 95 96 In doubt, say 'Y'. 97 98config EDAC_AMD64 99 tristate "AMD64 (Opteron, Athlon64)" 100 depends on EDAC_MM_EDAC && AMD_NB && EDAC_DECODE_MCE 101 help 102 Support for error detection and correction of DRAM ECC errors on 103 the AMD64 families (>= K8) of memory controllers. 104 105config EDAC_AMD64_ERROR_INJECTION 106 bool "Sysfs HW Error injection facilities" 107 depends on EDAC_AMD64 108 help 109 Recent Opterons (Family 10h and later) provide for Memory Error 110 Injection into the ECC detection circuits.
