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
       behaviour  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
              reinitialization. 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

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.
