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.
