Transmeta(TM) Crusoe(TM) LongRun(TM) support

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 (%).

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

The Transmeta(TM) Crusoe(TM) LongRun(TM) support first appeared in FreeBSD 4.4.

LongRun support and this manual page were written by Tamotsu HATTORI <athlete@kta.att.ne.jp> and Mitsuru IWASAKI <iwasaki@FreeBSD.org>.
June 30, 2001 FreeBSD 13.1-RELEASE
