As with most other Fedora projects and SIGs, all it takes is your interest. There are enough topics to cover around Power Management, so it's unlikely we will run out of work to do. :)
Feel free to join us on [irc://irc.freenode.net/fedora-power #fedora-power] IRC channel or [https://admin.fedoraproject.org/mailman/listinfo/power-management power-management] mailing list.

Fedora PowerManagement SIG

Mission

The PowerManagement SIG (Special Interest Group) is a group of Fedora contributors that want to improve the current state of power management and savings across the whole Fedora distribution. This starts at kernel components, goes over userland improvements up to usability and user experience on the Desktop.

Participants

  • Jaroslav Škarvada <jskarvad AT redhat DOT com> (package maintainer of powertop, pm-utils, acpid, apmd, bltk, PM measurement/benchmarking and tuned upstream)
  • Jan Včelák <jvcelak AT redhat DOT com> (package maintainer / tuned upstream)
  • Jan Scotka <jscotka@redhat.com> (QA coverage)
  • Juraj Marko <jmarko@redhat.com> (QA coverage)
  • Vratislav Podzimek <vpodzime (at) redhat (dot) com> (measurement)

Joining the SIG

As with most other Fedora projects and SIGs, all it takes is your interest. There are enough topics to cover around Power Management, so it's unlikely we will run out of work to do. :) Feel free to join us on #fedora-power IRC channel or power-management mailing list.

How you can help

  • Meetings:We will hold weekly meetings to discuss the general topic: IRC meetings - Every Wednesday at 14:00 - 15:00 UTC on #fedora-meeting (if there are attendance)
