Revision as of 20:15, 6 April 2011
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.
- Create virt profile.
- Include better integration of PM-QoS (e.g. correct support for PS-Poll).
- Add feature: tuned profiles creation from suggestions.
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.
Gnome
- Add UI notifications for suspend / hibernate failures.
Kernel
- Support for XHCI (USB3) suspend. [F15?]
- Fix suspend/resume for Intel 82801I USB controller.
- Add suspend/resume support to CDROM driver.
- Fix ThinkPad T500 supend/resume docking station issues.
Packaging
- Overview cpupowerutils project and get it to Fedora, announcement: http://lists.linux-foundation.org/pipermail/linux-pm/2011-March/030543.html
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.
