EDAC-UTIL(1)						   EDAC error reporting utility 					      EDAC-UTIL(1)

NAME

       edac-util - EDAC error reporting utility.

SYNOPSIS

       edac-util [OPTION]...

DESCRIPTION

       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.

OPTIONS

       -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 combina-
	      tions, 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. Addition-
	      ally, the use of --quiet will suppress all informational and debug messages, displaying only fatal errors.

       -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 printed.

       -r, --report=report,...
	      Specify  the report to generate. Currently, the available reports are default, simple, 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.

EDAC REPORTS

       default
	      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 combination with attrib-
	      uted 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 information. 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 usu-
	      ally 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:

	      MC:(csrow|noinfo):(label|all):(UE|CE):count

	      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.

NAME

       Tcl_BackgroundError - report Tcl error that occurred in background processing

SYNOPSIS

       #include <tcl.h>

       Tcl_BackgroundError(interp)

ARGUMENTS

       Tcl_Interp *interp (in)		Interpreter in which the error occurred.
_________________________________________________________________

DESCRIPTION

       This  procedure	is typically invoked when a Tcl error occurs during "background processing" such as executing an event handler.  When such
       an error occurs, the error condition is reported to Tcl or to a widget or some other C code, and there is not usually any obvious  way  for
       that  code  to  report  the  error  to the user.  In these cases the code calls Tcl_BackgroundError with an interp argument identifying the
       interpreter in which the error occurred.  At the time Tcl_BackgroundError is invoked, the interpreter's result is expected  to  contain	an
       error  message.	Tcl_BackgroundError will invoke the command registered in that interpreter to handle background errors by the interp bger-
       ror command.  The registered handler command is meant to report the error in an application-specific fashion.  The handler command receives
       two arguments, the result of the interp, and the return options of the interp at the time the error occurred.  If the application registers
       no handler command, the default handler command will attempt to call bgerror to report the error.   If  an  error  condition  arises  while
       invoking the handler command, then Tcl_BackgroundError reports the error itself by printing a message on the standard error file.

       Tcl_BackgroundError  does  not  invoke  the  handler  command immediately because this could potentially interfere with scripts that are in
       process at the time the error occurred.	Instead, it invokes the handler command later as an idle callback.

       It is possible for many background errors to accumulate before the handler command is invoked.  When this happens, each of  the	errors	is
       processed  in  order.   However,  if the handle command returns a break exception, then all remaining error reports for the interpreter are
       skipped.
