\fB-turbostat\fR
Use turbostat to execute the command in freeze mode (default: disabled). This
will provide turbostat output in the log which will tell you which actual
power modes were entered.
\fB-noturbostat\fR
By default, if turbostat is found and the requested mode is freeze, sleepgraph
will execute the suspend via turbostat and collect data in the timeline log.
This option disables the use of turbostat.
