NAME
       cpufreqd - intelligently monitor and manipulate CPU frequency

SYNOPSIS
       cpufreqd [-Dmhv] [-f filename] [-V verbosity]

DESCRIPTION
       cpufreqd	 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 4

SIGNALS
       SIGHUP This lets cpufreqd perform a re-initialization.  The  configura‐
	      tion  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 -D

NOTES
       Some 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  reinitial‐
	      ization. This has the effect of needing to send an HUP signal if
	      inserting a new battery, otherwise battery measurement won't  be
	      correct.

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). (Not yet implemented in
	      cpufreqd-2.0)

       /etc/cpufreqd.conf
	      cpufreqd configuration file

SEE ALSO
       cpufreqd.conf(5),syslogd(8),cpufreqd-set(1),cpufreqd-get(1)

BUGS
       Multiple CPUs are not considered separately thus the same policy is set
       in  every available CPU.	 Battery can only be specified in percent, not
       in minutes remaining.
