15	help
16	  EDAC is a subsystem along with hardware-specific drivers designed to
17	  report hardware errors. These are low-level errors that are reported
18	  in the CPU or supporting chipset or other subsystems:
19	  memory errors, cache errors, PCI errors, thermal throttling, etc..
20	  If unsure, select 'Y'.
21
22	  The mailing list for the EDAC project is linux-edac@vger.kernel.org.

37	help
38	  This turns on debugging information for the entire EDAC subsystem.
39	  You do so by inserting edac_module with "edac_debug_level=x." Valid
40	  levels are 0-4 (from low to high) and by default it is set to 2.
41	  Usually you should select 'N' here.

48	  Enable this option if you want to decode Machine Check Exceptions
49	  occurring on your machine in human-readable form.
50
51	  You should definitely say Y here in case you want to decode MCEs
52	  which occur really early upon boot, before the module infrastructure
53	  has been initialized.

55config EDAC_GHES
56	bool "Output ACPI APEI/GHES BIOS detected errors via EDAC"
57	depends on ACPI_APEI_GHES && (EDAC=y)
58	help
59	  Not all machines support hardware-driven error report. Some of those
60	  provide a BIOS-driven error report mechanism via ACPI, using the
61	  APEI/GHES driver. By enabling this option, the error reports provided
62	  by GHES are sent to userspace via the EDAC API.
63
64	  When this option is enabled, it will disable the hardware-driven
65	  mechanisms, if a GHES BIOS is detected, entering into the
66	  "Firmware First" mode.
67
68	  It should be noticed that keeping both GHES and a hardware-driven
69	  error mechanism won't work well, as BIOS will race with OS, while
70	  reading the error registers. So, if you want to not use "Firmware
71	  first" GHES error mechanism, you should disable GHES either at
72	  compilation time or by passing "ghes.disable=1" Kernel parameter
73	  at boot time.
74
75	  In doubt, say 'Y'.

82	  the AMD64 families (>= K8) of memory controllers.
83
84	  When EDAC_DEBUG is enabled, hardware error injection facilities
85	  through sysfs are available:
86
87	  AMD CPUs up to and excluding family 0x17 provide for Memory
88	  Error Injection into the ECC detection circuits. The amd64_edac
89	  module allows the operator/user to inject Uncorrectable and
90	  Correctable errors into DRAM.
91
92	  When enabled, in each of the respective memory controller directories
93	  (/sys/devices/system/edac/mc/mcX), there are 3 input files:
94
95	  - inject_section (0..3, 16-byte section of 64-byte cacheline),
96	  - inject_word (0..8, 16-bit word of 16-byte section),
97	  - inject_ecc_vector (hex ecc vector: select bits of inject word)
98
99	  In addition, there are two control files, inject_read and inject_write,
100	  which trigger the DRAM ECC Read and Write respectively.
