cpufreqd - intelligently monitor and manipulate CPU frequency
cpufreqd [-Dmhv] [-f filename] [-V verbosity]
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
stay in foreground (used to debug).

-f filename, --file=filename
Specify the configuration file to read. The default is

verbosity level from 0 (less verbose) to 7 (most verbose).
Default verbosity is 4
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)
cpufreqd will terminate.
Some ACPI implementations are very cpu-consuming when reading the info
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.

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.
