Projects / cpufrequtils


The cpufrequtils package consists of a library which offers an unified access method for userspace tools and programs to the CPU frequency and voltage scaling (cpufreq) subsystem in the Linux kernel, the "cpufreq-info" and "cpufreq-set" tools to determine and set cpufreq settings, and debug tools helpful if frequency scaling doesn't work as expected.

Recent releases

  •  10 Aug 2008 19:03

    Release Notes: The cpufrequtils library can again rely on the (deprecated) proc interface to the Linux kernel cpufreq subsystem. Furthermore, the cpufreq mailing list changed, so update the address where bug reports are sent.

      Release Notes: The most user-visible change of this release is the addition of statisitics output for cpufreq-info. The cpufrequtils library "libcpufreq" was updated accordingly, and it doesn't depend on libsysfs any longer.

      •  25 May 2008 14:51

        Release Notes: Czech and Portuguese translations have been added. A few kernel debug module updates were made.

        •  01 Jun 2006 12:45

          Release Notes: This release includes a couple of build and Makefile fixes and also a patch which causes cpufrequtils to always set the maximum frequency before the minimum frequency on a policy change, as the kernel expects.

          •  26 Mar 2006 10:41

            Release Notes: This release introduces a Makefile-based build system instead of autotools and is the first in the new numbering scheme (cpufrequtils-001 is newer and more advanced than cpufrequtils-0.4).
