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
