libcpufreq

"libcpufreq" is a library which offers a unified access method for userspace tools and programs to the cpufreq core and drivers in the Linux kernel. This allows for code reduction in userspace tools, a clean implementation of the interaction to the cpufreq core, and support for both the sysfs and proc interfaces [depending on configuration, see below].

utils

"cpufreq-info" determines current cpufreq settings, and provides useful debug information to users and bug-hunters. "cpufreq-set" allows to set a specific frequency and/or new cpufreq policies without having to type "/sys/devices/system/cpu/cpu0/cpufreq" all the time.

debug

A few debug tools helpful for cpufreq have been merged into this package, but as they are highly architecture specific they are not built by default.

compilation and installation

make
su
make install

should suffice on most systems. It builds default libcpufreq, cpufreq-set and cpufreq-info files and installs them in /usr/lib and /usr/bin, respectively. If you want to set up the paths differently and/or want to configure the package to your specific needs, you need to open "Makefile" with an editor of your choice and edit the block marked CONFIGURATION.

THANKS

Many thanks to Mattia Dongili who wrote the autotoolization and libtoolization, the manpages and the italian language file for cpufrequtils; to Dave Jones for his feedback and his dump_psb tool; to Bruno Ducrot for his powernow-k8-decode and intel_gsic tools as well as the french language file; and to various others commenting on the previous (pre-)releases of cpufrequtils.
