CPUFREQD(8) CPUFREQD(8)NAMEcpufreqd - intelligently monitor and manipulate CPU frequencySYNOPSIScpufreqd [-Dmhv] [-f filename] [-V verbosity]DESCRIPTIONcpufreqd is used to monitor the status of the system and adjust the frequency of the CPU according to the user configuration. The behav- iour of the daemon is fully configurable. Logs are reported through syslogd.PARAMETERS-D, --no-daemon stay in foreground (used to debug). -m, --manual start in manual mode. -f filename, --file=filename Specify the configuration file to read. The default is /etc/cpufreqd.conf. -h, --help Display command line help. -v, --version Display the version number of the daemon. -V, --verbosity verbosity level from 0 (less verbose) to 7 (most verbose). Default verbosity is 4SIGNALSSIGHUP This lets cpufreqd perform a re-initialization. The configuration file (default is /etc/cpufreqd.conf) will be re-read and probes re-done. (Not yet implemented in cpufreqd-2.0) SIGINT, SIGTERM cpufreqd will terminate.EXAMPLES/usr/sbin/cpufreqd -DNOTESSome ACPI implementations are very cpu-consuming when reading the info file of system batteries. Cpufreqd implements a simple workaround that avoids reading that file except on initialization or reinitializa- tion. This has the effect of needing to send an HUP signal if inserting a new battery, otherwise battery measurement won't be cor- rect.FILES/sys/devices/system/cpu/cpu*/cpufreq kernel cpu frequency interface /proc/cpufreq old deprecated kernel cpu frequency interface (please avoid it) /proc/acpi kernel power management interface (ACPI) /proc/apm kernel power management interface (APM) /proc/pmu kernel power management interface (PMU).

Battery can only be specified in percent, not in minutes remaining.AUTHORGeorge Staikos <staikos@0wned.org> Mattia Dongili <malattia@linux.it> Rene Rebe <rene@rocklinux.org> 05 May 2005 CPUFREQD(8)
