\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.
