2016-12-15docs-rst: admin-guide: add documentation for EDACMauro Carvalho Chehab1-1190/+0
EDAC is part of the Kernel's RAS facilities, with is useful for system admins to detect errors. So, add it to the admin's guide. Signed-off-by: Mauro Carvalho Chehab <mchehab@s-opensource.com>
2016-12-15edac.txt: Improve documentation, adding RAS introductionMauro Carvalho Chehab1-39/+248
The edac.txt assumes that the reader has already deep knowledge on RAS features. However, this may not be the case. So, add an introduction chapter explaining the main concepts that are used by the EDAC subsystem and by other RAS drivers within the Kernel.

2016-12-15edac.txt: update information about newer Intel CPUsMauro Carvalho Chehab1-15/+29
There's a chapter at edac.rst written by the time Nehalem support was added. Such information is used not only by the Nehalem driver (i7core_edac), but by all newer Intel CPU architectures that are supported by i7core_edac, sb_edac and sbx_edac drivers. Update the information to reflect that. Signed-off-by: Mauro Carvalho Chehab <mchehab@s-opensource.com>
2016-12-15edac.txt: remove info that the Nehalem EDAC is experimentalMauro Carvalho Chehab1-4/+0
This driver has been there for almost 3 years, without any conceptual changes. So, it is not experimental anymore, and won't likely have any changes at the API or on log outputs. Signed-off-by: Mauro Carvalho Chehab <mchehab@s-opensource.com>
2016-12-15edac.txt: convert EDAC documentation to ReSTMauro Carvalho Chehab1-256/+295
Converts the EDAC driver subsystem documentation to ReST: - Put paragraph titles in lower case; - Add code blocks where needed; - Convert tables to ReST markup; - Mark filesystem and module names as verbatim; - Adjust document to be properly displayed in html. Signed-off-by: Mauro Carvalho Chehab <mchehab@s-opensource.com>
2016-12-15edac.txt: add a section explaining the dimmX and rankX directoriesMauro Carvalho Chehab1-0/+120
Documentation for those are missing at the EDAC description. I guess we end by moving such descriptions in the past to the ABI document (or only added it there), but it means that the EDAC documentation is incomplete. So, add it there. Signed-off-by: Mauro Carvalho Chehab <mchehab@s-opensource.com>

2015-09-29Documentation/EDAC: Add reference documents section for amd64_edacAravind Gopalakrishnan1-0/+46
This section used to be in amd64_edac.h. Move it here as it is a more natural place to put all documentation-related info. Add links to the BKDGs while at it.

Do some initial cleanup, more probably will come. - Move credits section to the end - Update maintainers - Drop sourceforge reference - project is long upstream now - Reformat sections - Reformat paragraphs - Clarify text - Bring it up-to-date - Drop useless "future hardware scanning" section Signed-off-by: Borislav Petkov <bp@suse.de>

2012-06-11edac: move documentation ABI to ABI/testing/sysfs-devices-edacMauro Carvalho Chehab1-104/+8
The EDAC MC API is currently stored at the wrong place. Move the parts of the EDAC MC ABI that will be kept to ABI/testing/sysfs-devices-edac. The Date: field were added based on git timestamps for the git commit patches that added the functionality at edac.txt.

2012-03-19EDAC: Correct scrub rate APIBorislav Petkov1-2/+2
The original scrub rate API definition states that if scrub rate accessors are not implemented, a negative value (-1) should be written to the sysfs file (/sys/devices/system/edac/mc/mc<N>/sdram_scrub_rate, where N is the memory controller number on the system). This is counter-intuitive and awkward at the very least because, when setting the scrub rate, userspace has to write to sysfs and then read it back to check error status of the operation. As Tony notes, best it would be to not have the sdram_scrub_rate in sysfs if scrub rate support is not implemented. It is too late about that and a bunch of drivers on a bunch of arches would need to be changed and tested which is not a trivial task ATM. Instead, settle for the next best thing of returning -ENODEV when implementation is missing and -EINVAL when there was an error encountered while setting the scrub rate.
