SIGs/PowerManagement/Todos

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

Docs

• Update the Power Management Guide to reflect the current state of F15 (link to old F14 guide: F14 Power Management Guide).

Tuned

• irqbalance for powersaving profiles.
• Enable sched_smt_power_savings.
• Enable hda_intel powersaving.
• Create virt profile.
• Include better integration of PM-QoS (e.g. correct support for PS-Poll).
• RFE: tuned profiles creation from PowerTOP suggestions.

PowerTOP

• Add support for IPMI power meter (and maybe iLO2).

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).
    • Simple iMacros script generator for automated youtube/novinky.cz/google multi-tabs browsing is located at http://jkaluza.fedorapeople.org/imacros.py . Thanks to imacros should work in both Firefox and IE (also in opera).
  • 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 and its usability for power management testing / comparisons. Also investigate OS independent benchmarks for inter OS comparisons.

Gnome

• Add UI notifications for suspend / hibernate failures.

Kernel

• Fix suspend/resume for Intel 82801I USB controller.
• Add suspend/resume support to CDROM driver.
• Fix ThinkPad T500 supend/resume docking station issues.

Other

• Create PM SIG logo [Work in progress, thanks to Pavel Křivánek for contributing graphics].
• 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 DDC/CI to control settings of external LCDs. [ddccontrol packaging in progress]
• Fix: LiveCD doesn't support resume from swap located on LVM.
