  	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.

  	  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'.

  	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.
