       Transmeta(TM) Crusoe(TM) LongRun(TM) utility

       longrun [-c device] [-m device] [-hlpv] [-f flag] [-s low high]

       The  longrun  utility  is  used	to control and query LongRun settings on Transmeta Crusoe

       -c device
	      Set the CPUID device.  The default CPUID device is /dev/cpu/0/cpuid.

       -m device
	      Set the MSR device.  The default CPUID device is /dev/cpu/0/msr.

       -h     Print help.

       -l     List LongRun information about available performance levels for the CPU.

	      The following values are reported on all Transmeta CPUs that implement LongRun.

		 %	An available performance level, expressed as a	percentage  of	range  of
			available  core  CPU  frequencies.  0 corresponds to the lowest available
			frequency and 100 corresponds to the highest.

		 MHz	The core CPU frequency at that level.

		 Volts	The core CPU voltage at that level.

		 usage	The power usage relative to the maximum performance level.

       -p     Print current LongRun settings and status:  whether  LongRun  is	enabled,  whether
	      LongRun  Thermal	Extensions  are  active,  the  current LongRun performance window
	      (expressed as a percentile range), the current LongRun performance level (expressed
	      as a percentile), and the current LongRun flags.

       -v     Be more verbose.

       -f flag
	      Set  a  LongRun  mode flag.  Currently, the two supported flags are performance and
	      economy.	This controls whether the processor is in "performance mode" or  "economy

       -s low high
	      Set  the	current LongRun performance window as a percentile range.  The low number
	      cannot be greater than the high number.  The minimum and maximum performance values
	      accepted by the CPU are 0 and 100, respectively.

       No environment variables are used.

       This program requires that the Linux CPUID and MSR devices be compiled into the kernel (or
       loaded as kernel modules), that the CPUID character device be readable, and that  the  MSR
       character device be both readable and writable.
