Transmeta(tm) crusoe(tm) longrun(tm) support
Usage
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
