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