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]. + + +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. + + + Dominik Brodowski |
