Conclusions from Energy Aware Scheduling sessions at the latest Kernel Summit identified a need for tools that would assess power consumption of the system These tools would be used to prove efficiency of scheduler patches by comparing power consumption before and after they were applied.
Attached is the proposal for the idlestat tool. The purpose of this patch is to solicit feedback on tool's features, possible enhancements, etc. Source code and sample idlestat report are provided for reference. Please review and provide comments in anticipation of further development.
