+What: /sys/devices/system/edac/mc/mc*/reset_counters
+Date: January 2006
+Contact: linux-edac@vger.kernel.org
+Description: This write-only control file will zero all the statistical
+ counters for UE and CE errors on the given memory controller.
+ Zeroing the counters will also reset the timer indicating how
+ long since the last counter were reset. This is useful for
+ computing errors/time. Since the counters are always reset
+ at driver initialization time, no module/kernel parameter
+ is available.

+Date: January 2006
+Contact: linux-edac@vger.kernel.org

+Description: Read/Write attribute file that controls memory scrubbing.
+ The scrubbing rate used by the memory controller is set by
+ writing a minimum bandwidth in bytes/sec to the attribute file.
+ The rate will be translated to an internal value that gives at
+ least the specified rate.
+ Reading the file will return the actual scrubbing rate employed.
+ If configuration fails or memory scrubbing is not implemented,

+ stick. For rank*/size, this is the size, in MB for one rank
+ of the DIMM memory stick. On single rank memories (1R), this

+ this is half the size of the total DIMM memories.

+Date: April 2012
+Contact: Mauro Carvalho Chehab <mchehab@redhat.com>
+ linux-edac@vger.kernel.org
+Description: This control file allows this DIMM to have a label assigned
+ to it. With this label in the module, when errors occur
+ the output can provide the DIMM label in the system log.
+ This becomes vital for panic events to isolate the
+ cause of the UE event.
+ DIMM Labels must be assigned after booting, with information
+ that correctly identifies the physical slot with its
+ silk screen label. This information is currently very
+ motherboard specific and determination of this information
+ must occur in userland at this time.
