| 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/> |

| 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'. |

| 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'. |

| 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. |
