longrun

LONGRUN(1)						      General Commands Manual							LONGRUN(1)

NAME

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

SYNOPSIS

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

DESCRIPTION

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

       -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 mode".

       -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.

ENVIRONMENT

       No environment variables are used.

FILES

       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.
