4Description:	This write-only control file will zero all the statistical
5		counters for UE and CE errors on the given memory controller.
6		Zeroing the counters will also reset the timer indicating how
7		long since the last counter were reset. This is useful for
8		computing errors/time.  Since the counters are always reset
9		at driver initialization time, no module/kernel parameter
10		is available.

13Date:		January 2006
14Contact:	linux-edac@vger.kernel.org
15Description:	This attribute file displays how many seconds have elapsed
16		since the last counter reset. This can be used with the error
17		counters to measure error rates.

22Description:	This attribute file displays the type of memory controller
23		that is being utilized.

26Date:		January 2006

28Description:	This attribute file displays, in count of megabytes, of memory
29		that this memory controller manages.

32Date:		January 2006
33Contact:	linux-edac@vger.kernel.org
34Description:	This attribute file displays the total count of uncorrectable
35		errors that have occurred on this memory controller. If
36		panic_on_ue is set, this counter will not have a chance to
37		increment, since EDAC will panic the system

40Date:		January 2006
41Contact:	linux-edac@vger.kernel.org
42Description:	This attribute file displays the number of UEs that have
43		occurred on this memory controller with no information as to
44		which DIMM slot is having errors.

46What:		/sys/devices/system/edac/mc/mc*/ce_count
47Date:		January 2006
48Contact:	linux-edac@vger.kernel.org
49Description:	This attribute file displays the total count of correctable
50		errors that have occurred on this memory controller. This
51		count is very important to examine. CEs provide early
52		indications that a DIMM is beginning to fail. This count
53		field should be monitored for non-zero values and report
54		such information to the system administrator.

57Date:		January 2006
58Contact:	linux-edac@vger.kernel.org
59Description:	This attribute file displays the number of CEs that
60		have occurred on this memory controller wherewith no
61		information as to which DIMM slot is having errors. Memory is
62		handicapped, but operational, yet no information is available
63		to indicate which slot the failing memory is in. This count
64		field should be also be monitored for non-zero values.

66What:		/sys/devices/system/edac/mc/mc*/sdram_scrub_rate
67Date:		February 2007
68Contact:	linux-edac@vger.kernel.org
69Description:	Read/Write attribute file that controls memory scrubbing.
70		The scrubbing rate used by the memory controller is set by
71		writing a minimum bandwidth in bytes/sec to the attribute file.
72		The rate will be translated to an internal value that gives at
73		least the specified rate.
74		Reading the file will return the actual scrubbing rate employed.
75		If configuration fails or memory scrubbing is not implemented,
76		the value of the attribute file will be -1.
