DVFS for atom D2000 processor

Srinath_A_ — Wed, 20 Nov 2013 02:00:04 GMT

This is my first exposure to DVFS and I would like to be clarified on a few points

The data sheet for the processor says that it supports lots of P-states.

It also says that

Frequency selection is software controlled by writing to processor MSRs. The voltage is optimized based on the selected frequency:

My questions are

Is it possible to independently set the voltage/frequency and if so how and to which register do we write to?

What are values for various frequencies?

Regards

Srinath
