Subject: [RFC PATCH 0/2] sched: proposal for idlestat scheduler benchmarking tool

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.

Regards, Zoran
