15	help
16	  EDAC is designed to report errors in the core system.
17	  These are low-level errors that are reported in the CPU or
18	  supporting chipset or other subsystems:
19	  memory errors, cache errors, PCI errors, thermal throttling, etc..
20	  If unsure, select 'Y'.
21
22	  If this code is reporting problems on your system, please
23	  see the EDAC project web pages for more information at:
24
25	  <http://bluesmoke.sourceforge.net/>
26
27	  and:

38	default y

40	  Enable the compatibility sysfs nodes.
41	  Use 'Y' if your edac utilities aren't ported to work with the newer
42	  structures.
43
44config EDAC_DEBUG
45	bool "Debugging"
46	help
47	  This turns on debugging information for the entire EDAC subsystem.
48	  You do so by inserting edac_module with "edac_debug_level=x." Valid
49	  levels are 0-4 (from low to high) and by default it is set to 2.
50	  Usually you should select 'N' here.

56	---help---
57	  Enable this option if you want to decode Machine Check Exceptions
58	  occurring on your machine in human-readable form.
59
60	  You should definitely say Y here in case you want to decode MCEs
61	  which occur really early upon boot, before the module infrastructure
62	  has been initialized.

64config EDAC_MM_EDAC
65	tristate "Main Memory EDAC (Error Detection And Correction) reporting"
66	select RAS
67	help
68	  Some systems are able to detect and correct errors in main
69	  memory.  EDAC can report statistics on memory error
70	  detection and correction (EDAC - or commonly referred to ECC
71	  errors).  EDAC will also try to decode where these errors
72	  occurred so that a particular failing memory module can be
73	  replaced.  If unsure, select 'Y'.
74
75config EDAC_GHES
76	bool "Output ACPI APEI/GHES BIOS detected errors via EDAC"
77	depends on ACPI_APEI_GHES && (EDAC_MM_EDAC=y)
78	default y
79	help
80	  Not all machines support hardware-driven error report. 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'.

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. The amd64_edac module
111	  allows the operator/user to inject Uncorrectable and Correctable
112	  errors into DRAM.
113
114	  When enabled, in each of the respective memory controller directories
115	  (/sys/devices/system/edac/mc/mcX), there are 3 input files:
116
117	  - inject_section (0..3, 16-byte section of 64-byte cacheline),
118	  - inject_word (0..8, 16-bit word of 16-byte section),
119	  - inject_ecc_vector (hex ecc vector: select bits of inject word)
120

122	  which trigger the DRAM ECC Read and Write respectively.
