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 Ta Vt integer Ta yes Ta LongRun mode:
- Ta Ta Ta 0: minimum frequency mode
- Ta Ta Ta 1: power-saving mode
- Ta Ta Ta 2: performance mode
- Ta Ta Ta 3: maximum frequency mode
- hw.crusoe.frequency Ta Vt integer Ta no Ta Current frequency (MHz).
- hw.crusoe.voltage Ta Vt integer Ta no Ta Current voltage (mV).
- hw.crusoe.percentage Ta Vt integer Ta no Ta 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"
