cpufreqd

CPUFREQD(8)															       CPUFREQD(8)

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 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 -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 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). (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.
