I have bought the android develop phone 2. I want to do some research about power management on ADP2. But I wonder if ADP2 support Dynamic Voltage and Frequency Scaling(DVFS). That means whether we can change the CPU frequency dynamically on ADP2. Previously, someone told me that I can rebuild the android OS kernel and turn on the user space and then I can set the CPU frequency. I have tried to rebuild the kernel just as " http://source.android.com/documentation/building-for-dream"; said. But I still don't know how to turn on the user space when built the kernel and don't know how to set the CPU frequency on ADP2. Would you kindly give me some support on how to dynamically set the CPU frequency on ADP2? I will appreciate very very much for your support.
