# # EDAC Kconfig # Copyright (c) 2008 Doug Thompson www.softwarebitmaker.com # Licensed and distributed under the GPL config EDAC_ATOMIC_SCRUB bool config EDAC_SUPPORT bool menuconfig EDAC tristate "EDAC (Error Detection And Correction) reporting" depends on HAS_IOMEM && EDAC_SUPPORT && RAS help EDAC is a subsystem along with hardware-specific drivers designed to report hardware errors. 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'. The mailing list for the EDAC project is linux-edac@vger.kernel.org. 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" select DEBUG_FS 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_GHES bool "Output ACPI APEI/GHES BIOS detected errors via EDAC" depends on ACPI_APEI_GHES && (EDAC=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)" depends on AMD_NB && EDAC_DECODE_MCE help Support for error detection and correction of DRAM ECC errors on the AMD64 families (>= K8) of memory controllers.

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_AL_MC tristate "Amazon's Annapurna Lab Memory Controller" depends on (ARCH_ALPINE || COMPILE_TEST) help Support for error detection and correction for Amazon's Annapurna Labs Alpine chips which allow 1 bit correction and 2 bits detection. config EDAC_AMD76X tristate "AMD 76x (760, 762, 768)" depends on PCI && X86_32 help Support for error detection and correction on the AMD 76x series of chipsets used with the Athlon processor. config EDAC_E7XXX tristate "Intel e7xxx (e7205, e7500, e7501, e7505)" depends on PCI && X86_32 help Support for error detection and correction on the Intel E7205, E7500, E7501 and E7505 server chipsets. config EDAC_E752X tristate "Intel e752x (e7520, e7525, e7320) and 3100" depends on PCI && X86 help Support for error detection and correction on the Intel E7520, E7525, E7320 server chipsets. config EDAC_I82443BXGX tristate "Intel 82443BX/GX (440BX/GX)" depends on PCI && X86_32 depends on BROKEN help Support for error detection and correction on the Intel 82443BX/GX memory controllers (440BX/GX chipsets). config EDAC_I82875P tristate "Intel 82875p (D82875P, E7210)" depends on PCI && X86_32 help Support for error detection and correction on the Intel DP82785P and E7210 server chipsets. config EDAC_I82975X tristate "Intel 82975x (D82975x)" depends on PCI && X86 help Support for error detection and correction on the Intel DP82975x server chipsets. config EDAC_I3000 tristate "Intel 3000/3010" depends on PCI && X86 help Support for error detection and correction on the Intel 3000 and 3010 server chipsets. config EDAC_I3200 tristate "Intel 3200" depends on PCI && X86 help Support for error detection and correction on the Intel 3200 and 3210 server chipsets. config EDAC_IE31200 tristate "Intel e312xx" depends on PCI && X86 help Support for error detection and correction on the Intel E3-1200 based DRAM controllers. config EDAC_X38 tristate "Intel X38" depends on PCI && X86 help Support for error detection and correction on the Intel X38 server chipsets. config EDAC_I5400 tristate "Intel 5400 (Seaburg) chipsets" depends on PCI && X86 help Support for error detection and correction the Intel i5400 MCH chipset (Seaburg). config EDAC_I7CORE tristate "Intel i7 Core (Nehalem) processors" depends on PCI && X86 && X86_MCE_INTEL help Support for error detection and correction the Intel i7 Core (Nehalem) Integrated Memory Controller that exists on newer processors like i7 Core, i7 Core Extreme, Xeon 35xx and Xeon 55xx processors. config EDAC_I82860 tristate "Intel 82860" depends on PCI && X86_32 help Support for error detection and correction on the Intel 82860 chipset. config EDAC_R82600 tristate "Radisys 82600 embedded chipset" depends on PCI && X86_32 help Support for error detection and correction on the Radisys 82600 embedded chipset. config EDAC_I5000 tristate "Intel Greencreek/Blackford chipset" depends on X86 && PCI help Support for error detection and correction the Intel Greekcreek/Blackford chipsets. config EDAC_I5100 tristate "Intel San Clemente MCH" depends on X86 && PCI help Support for error detection and correction the Intel San Clemente MCH. config EDAC_I7300 tristate "Intel Clarksboro MCH" depends on X86 && PCI help Support for error detection and correction the Intel Clarksboro MCH (Intel 7300 chipset). config EDAC_SBRIDGE tristate "Intel Sandy-Bridge/Ivy-Bridge/Haswell Integrated MC" depends on PCI && X86_64 && X86_MCE_INTEL && PCI_MMCONFIG help Support for error detection and correction the Intel Sandy Bridge, Ivy Bridge and Haswell Integrated Memory Controllers. config EDAC_SKX tristate "Intel Skylake server Integrated MC" depends on PCI && X86_64 && X86_MCE_INTEL && PCI_MMCONFIG && ACPI depends on ACPI_NFIT || !ACPI_NFIT # if ACPI_NFIT=m, EDAC_SKX can't be y select DMI select ACPI_ADXL help Support for error detection and correction the Intel Skylake server Integrated Memory Controllers.
