SIGs/PowerManagement/Todos

This page holds to do list, suggestions and ideas for PM improvements.

Tuned

• irqbalance for powersaving profiles
• enable sched_smt_power_savings
• enable hda_intel powersaving
• dynamic tunings for EEEPC FSB (worked on by jskarvad)

Benchmarks

• Create infrastructure for running 'real life' loads.
• Create 'real life' loads, e.g. for WWW browsing, watching video, development and whatever are users doing with their computers - similar to BLTK loads but more advanced and CPU intensive tasks.
  • We can simulate web browsing via Chickenfoot, Greasemonkey, iMacros Firefox extensions (currently Chickenfoot doesn't support FF4).
  • Another idea is to use the XULRunner (thanks to Pavel Křivánek for contributing the example code): http://jskarvad.fedorapeople.org/loadGenerator.zip
• Investigate available free benchmarks, e.g. AB, DOTS, Phoronix Test Suite, etc. and its usability for power management testing / comparisons. Also investigate OS independent benchmarks for inter OS comparisons.

Other

• Prepare Test Day on 2011-03-24.
• Add PM support to cronie (wrapper) to be able to postpone running of battery demanding tasks. [Work in progress]
• Add PM support to services, e.g. support for battery / AC profiles.
• Add support for XHCI (USB3) suspend. [F15?]
• Add support for DDC/CI to control settings of external LCDs. [ddccontrol packaging in progress]
• Include better integration of PM-QoS (e.g. correct support for PS-Poll).
• Tuned profiles creation from the PowerTOP suggestions.
• Add UI notifications for suspend / hibernate failures.
