Blueprint: hardware-p-kernel-power-management

Power Management:

Write up results from wake events analysis and file lots of bugs

Write cpustat: git://kernel.ubuntu.com/cking/cpustat.git
Test CPU utilization, results:

Investigate MSR_IA32_ENERGY_PERF_BIAS on sandybridge, no +ve results
need to rig up Ivybridge desktop to sanity check this.

LP#911325 – new pm-utils scripts to save power

Collect power measurements on Hardy, Lucid, Maverick, Natty, Oneiric, Precise
