       edac-util - EDAC error reporting utility.

       edac-util [OPTION]...

       The edac-util program reads information from EDAC (Error Detection and Correction) drivers
       in the kernel, using files exported by these drivers in sysfs. With no options,	edac-util
       will  report  any  uncorrected  error (UE) or corrected error (CE) information recorded by
       EDAC, along with any DIMM label information registered with EDAC.

       -h, --help
	      Display a summary of the command-line options.

       -q, --quiet
	      Quiet mode. For some reports, edac-util will report corrected and uncorrected error
	      counts  for  all	MC, csrow, and channel combinations, even if the current count of
	      errors is zero. The --quiet flag will suppress the display of  any  locations  with
	      zero  errors,  thus  creating  a	more terse report. No output will be generated if
	      there are zero total errors currently recorded by EDAC. Additionally,  the  use  of
	      --quiet  will  suppress all informational and debug messages, displaying only fatal

       -v, --verbose
	      Increase verbosity. Multiple -v's may be used.

       -s, --status
	      Displays the current status of EDAC  drivers.  edac-util	will  report  whether  it
	      detects  that  EDAC  drivers are loaded, and the number of memory controllers (MCs)
	      found in sysfs. In verbose mode, the MC id and name of each controller will also be

       -r, --report=report,...
	      Specify  the report to generate. Currently, the available reports are default, sim-
	      ple, full, ue, and ce.  These reports are detailed  in  the  EDAC  REPORTS  section
	      below. More than one report may be specified in a comma-separated list.

	      The  default  edac-util  report  is  generated  when the program is run without any
	      options. If there are no errors logged by EDAC, this report will display "No errors
	      to report." to stdout. Otherwise, error counts for each MC, csrow, channel combina-
	      tion with attributed errors are displayed, along with corresponding DIMM labels, if
	      these labels have been registered in sysfs.

	      The  default report will also display any errors that do not have any DIMM informa-
	      tion. These errors occur when errors are reported in the memory controller overflow
	      register,  indicating  that  more  than one error occurred during a given EDAC poll
	      cycle. It is usually obvious from which DIMM locations these errors were generated.

       simple The simple report reports total  corrected  and  uncorrected  errors  for  each  MC
	      detected	on the system. It also displays a tally of total errors. With the --quiet
	      option, only non-zero error counts are displayed.

       full   The full report generates a line of output for every MC, csrow, channel combination
	      found  in  EDAC sysfs. This includes counts of errors with no information ("noinfo"
	      errors). Output is of the form:


	      With the --quiet option, only non-zero error counts will be displayed.

       ue     This report simply displays the total number of Uncorrected Errors  (UEs)  detected
	      on the system.  With the --quiet option, output will be suppressed unless there are
	      1 or more errors to report.

       ce     This report simply displays the total number of Corrected Errors (CEs) detected  on
	      the  system.  With the --quiet option, output will be suppressed unless there are 1
	      or more errors to report.
