# # EDAC Kconfig # Copyright (c) 2008 Doug Thompson www.softwarebitmaker.com # Licensed and distributed under the GPL # config EDAC_SUPPORT bool menuconfig EDAC bool "EDAC (Error Detection And Correction) reporting" depends on HAS_IOMEM depends on X86 || PPC || TILE || ARM || EDAC_SUPPORT help EDAC is designed to report errors in the core system. These are low-level errors that are reported in the CPU or supporting chipset or other subsystems: memory errors, cache errors, PCI errors, thermal throttling, etc.. If unsure, select 'Y'. If this code is reporting problems on your system, please see the EDAC project web pages for more information at: <http://bluesmoke.sourceforge.net/> and: <http://buttersideup.com/edacwiki> There is also a mailing list for the EDAC project, which can be found via the sourceforge page. if EDAC config EDAC_LEGACY_SYSFS bool "EDAC legacy sysfs" default y help Enable the compatibility sysfs nodes. Use 'Y' if your edac utilities aren't ported to work with the newer structures. config EDAC_DEBUG bool "Debugging" help This turns on debugging information for the entire EDAC subsystem. You do so by inserting edac_module with "edac_debug_level=x." Valid levels are 0-4 (from low to high) and by default it is set to 2. Usually you should select 'N' here. config EDAC_DECODE_MCE tristate "Decode MCEs in human-readable form (only on AMD for now)" depends on CPU_SUP_AMD && X86_MCE_AMD default y ---help--- Enable this option if you want to decode Machine Check Exceptions occurring on your machine in human-readable form. You should definitely say Y here in case you want to decode MCEs which occur really early upon boot, before the module infrastructure has been initialized. config EDAC_MCE_INJ tristate "Simple MCE injection interface over /sysfs" depends on EDAC_DECODE_MCE default n help This is a simple interface to inject MCEs over /sysfs and test the MCE decoding code in EDAC. This is currently AMD-only. config EDAC_MM_EDAC tristate "Main Memory EDAC (Error Detection And Correction) reporting" select RAS help Some systems are able to detect and correct errors in main memory. EDAC can report statistics on memory error detection and correction (EDAC - or commonly referred to ECC errors). EDAC will also try to decode where these errors occurred so that a particular failing memory module can be replaced. If unsure, select 'Y'. config EDAC_GHES bool "Output ACPI APEI/GHES BIOS detected errors via EDAC" depends on ACPI_APEI_GHES && (EDAC_MM_EDAC=y) default y help Not all machines support hardware-driven error report. Some of those provide a BIOS-driven error report mechanism via ACPI, using the APEI/GHES driver. By enabling this option, the error reports provided by GHES are sent to userspace via the EDAC API. When this option is enabled, it will disable the hardware-driven mechanisms, if a GHES BIOS is detected, entering into the "Firmware First" mode. It should be noticed that keeping both GHES and a hardware-driven error mechanism won't work well, as BIOS will race with OS, while reading the error registers. So, if you want to not use "Firmware first" GHES error mechanism, you should disable GHES either at compilation time or by passing "ghes.disable=1" Kernel parameter at boot time. In doubt, say 'Y'. config EDAC_AMD64 tristate "AMD64 (Opteron, Athlon64) K8, F10h" depends on EDAC_MM_EDAC && AMD_NB && X86_64 && EDAC_DECODE_MCE help Support for error detection and correction of DRAM ECC errors on the AMD64 families of memory controllers (K8 and F10h) config EDAC_AMD64_ERROR_INJECTION bool "Sysfs HW Error injection facilities" depends on EDAC_AMD64 help Recent Opterons (Family 10h and later) provide for Memory Error Injection into the ECC detection circuits. The amd64_edac module allows the operator/user to inject Uncorrectable and Correctable errors into DRAM. When enabled, in each of the respective memory controller directories (/sys/devices/system/edac/mc/mcX), there are 3 input files: - inject_section (0..3, 16-byte section of 64-byte cacheline), - inject_word (0..8, 16-bit word of 16-byte section), - inject_ecc_vector (hex ecc vector: select bits of inject word) In addition, there are two control files, inject_read and inject_write, which trigger the DRAM ECC Read and Write respectively. config EDAC_AMD76X tristate "AMD 76x (760, 762, 768)" depends on EDAC_MM_EDAC && PCI && X86_32 help Support for error detection and correction on the
