 # white space is not allowed in value currently, except at the end where it is dropped
 #

 # In general all command line options that are not commands work here.
 # See man mcelog or mcelog --help for a list.
 # e.g. to enable the --no-syslog option use
 #no-syslog = yes   (or no to disable)
 # when the option has a argument
 #logfile = /tmp/logfile
 # below are the options which are not command line options.

 # Set CPU type for which mcelog decodes events:
 #cpu = type
 # For valid values for type please see mcelog --help.
 # If this value is set incorrectly the decoded output will be likely incorrect.
 # By default when this parameter is not set mcelog uses the CPU it is running on
 # on very new kernels the mcelog events reported by the kernel also carry
 # the CPU type which is used too when available and not overridden.

 # Enable daemon mode:
 #daemon = yes
