|
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.

Description: This attribute file displays how many seconds have elapsed

since the last counter reset. This can be used with the error

counters to measure error rates.

errors that have occurred on this memory controller. If

Description: This attribute file displays the total count of correctable

errors that have occurred on this memory controller. This
|

|
count is very important to examine. CEs provide early
|

|
indications that a DIMM is beginning to fail. This count
|

field should be monitored for non-zero values and report
|

such information to the system administrator.

Description: This attribute file displays the number of CEs that

have occurred on this memory controller wherewith no

information as to which DIMM slot is having errors. Memory is

handicapped, but operational, yet no information is available

to indicate which slot the failing memory is in. This count

|
||
|
|
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,
|
||
|
|
the value of the attribute file will be -1.
