NAME
longrun - Transmeta(TM) Crusoe(TM) LongRun(TM) support
SYNOPSIS
LongRun support is a collection of power saving modes for the Transmeta
Crusoe chips, similar in scope to Intel’s SpeedStep. The following
sysctl(8) MIBs control the different CPU modes:
Name Type Changeable Description
hw.crusoe.longrun integer yes LongRun mode:
0: minimum frequency
mode
1: power-saving mode
2: performance mode
3: maximum frequency
mode
hw.crusoe.frequency integer no Current frequency (MHz).
hw.crusoe.voltage integer no Current voltage (mV).
hw.crusoe.percentage integer no Processing performance
(%).
EXAMPLES
Print the current status:
% sysctl hw.crusoe
To set LongRun mode to performance oriented variable frequency mode (less
power savings):
# sysctl hw.crusoe.longrun=2
HISTORY
The Transmeta(TM) Crusoe(TM) LongRun(TM) support first appeared in
