CPU clock frequency


Hi,
I am using cpufreq utility in my linux kernel. The cpufreq package is good enough to change the cpu frequency on the fly. I study the source code to understand how it happens. Basically two files are changed namely
/proc/cpuinfo and
/sys/devices/system/cpu/cpu0/cpufreq/

But my question is how these files are linked with the hard ware
