Can the cpufreq driver run on the Beagle board?

Hello,

I am interested in designing energy-efficient DSP application on
beagle board, but am not sure if beagle board supports dynamic voltage/
frequency scaling (DVFS) and provides cpufreq driver.

Currently, OMAP3530 support dynamic voltage/frequency scaling.
Practically, it is implemented with the cpufreq framework in Linux,
which will dynamically adjust the operating performance point based on
CPU loading. And cpufreq driver can run on TI's OMAP3530 EVM.

But can the cpufreq driver and related API run on the Beagle board? If
it does, how to utilize it to realize DVFS? And is there any further
materials or manuals about it?

Thanks

yes, it does

Check the top-right corner of http://www.flickr.com/photos/koenkooi/4827023258/ that has the gnome cpufreq applet working.
