     59.SH "REMARKS"
     60.LP 
     61By default only values of core zero are displayed. How to display settings of
     62other cores is described in the cpupower(1) manpage in the \-\-cpu option section.
     63.LP 
     64You can't specify more than one of the output specific options \-o \-e \-a \-g \-p \-d \-l \-w \-f \-y.
     65.LP 
     66You also can't specify the \-o option combined with the \-c option.
