.Nd Transmeta(TM) Crusoe(TM) LongRun(TM) support
|
|
.Sh SYNOPSIS
|
|
LongRun support is a collection of power saving modes for the
|
|
Transmeta Crusoe chips, similar in scope to Intel's SpeedStep.
|
|
The following
|
|
.Xr sysctl 8
|
|
MIBs control the different CPU modes:
|
|
.Bl -column ".Va hw.crusoe.percentage" ".Vt integer" "Changeable"
|
|
.It Sy "Name Type Changeable Description"
|
|
.It Va hw.crusoe.longrun Ta Vt integer Ta yes Ta "LongRun mode:"
|
|
.It Ta Ta Ta "0: minimum frequency mode"
|
|
.It Ta Ta Ta "1: power-saving mode"
|
|
.It Ta Ta Ta "2: performance mode"
|
|
.It Ta Ta Ta "3: maximum frequency mode"
|
|
.It Va hw.crusoe.frequency Ta Vt integer Ta no Ta "Current frequency (MHz)."
|
|
.It Va hw.crusoe.voltage Ta Vt integer Ta no Ta "Current voltage (mV)."
|
|
.It Va hw.crusoe.percentage Ta Vt integer Ta no Ta "Processing performance (%)."
|
|
.El
|
|
.Sh EXAMPLES
|
|
Print the current status:
|
|
.Pp
|
|
.Dl "% sysctl hw.crusoe"
|
|
.Pp
|
|
To set LongRun mode to performance oriented variable frequency mode
|
|
(less power savings):
|
|
.Pp
|
|
.Dl "# sysctl hw.crusoe.longrun=2"
