1The cpufrequtils package (homepage:
2http://www.kernel.org/pub/linux/utils/kernel/cpufreq/cpufrequtils.html )
3consists of the following elements:

8On x86 pciutils is needed at runtime (-lpci).
9For compilation pciutils-devel (pci/pci.h) and a gcc version
10providing cpuid.h is needed.
11For both it's not explicitly checked for (yet).

15----------

17"libcpufreq" is a library which offers a unified access method for userspace
18tools and programs to the cpufreq core and drivers in the Linux kernel. This
19allows for code reduction in userspace tools, a clean implementation of
20the interaction to the cpufreq core, and support for both the sysfs and proc
21interfaces [depending on configuration, see below].

24compilation and installation
25----------------------------
26
27make
28su
29make install

31should suffice on most systems. It builds default libcpufreq,
32cpufreq-set and cpufreq-info files and installs them in /usr/lib and
33/usr/bin, respectively. If you want to set up the paths differently and/or
34want to configure the package to your specific needs, you need to open
35"Makefile" with an editor of your choice and edit the block marked
36CONFIGURATION.
