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. 93 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. 97 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 103 at boot time. 104 105 In doubt, say 'Y'. 106 107config EDAC_AMD64 108 tristate "AMD64 (Opteron, Athlon64)" 109 depends on EDAC_MM_EDAC && AMD_NB && EDAC_DECODE_MCE 110 help 111 Support for error detection and correction of DRAM ECC errors on 112 the AMD64 families (>= K8) of memory controllers. 113 114config EDAC_AMD64_ERROR_INJECTION 115 bool "Sysfs HW Error injection facilities" 116 depends on EDAC_AMD64 117 help 118 Recent Opterons (Family 10h and later) provide for Memory Error 119 Injection into the ECC detection circuits.
