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 Ta Type Ta 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 FreeBSD 4.4 .

Ken Thompson has an automobile which he helped design. Unlike most automobiles, it has neither speedometer, nor gas gauge, nor any of the other numerous idiot lights which plague the modern driver. Rather, if the driver makes a mistake, a giant “?” lights up in the center of the dashboard. “The experienced driver,” says Thompson, “will usually know what's wrong.”
