     longrun -- Transmeta(TM) Crusoe(TM) LongRun(TM) support

SYNOPSIS    [Toc]    [Back]

     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    [Toc]    [Back]

     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
