Fedora PowerManagement BaseOS SIG
Wakeups / Disk IO / Network IO
Goal: Reduce wakeup count of userland applications and unnecessary network and disk IO.
Plan: Audit system using various tools, provide guidance & fixes for problems.
- powertop
- diskdevstat (tuned-utils)
- netdevstat (tuned-utils)
Tracker bugs
- Tracker bug for over-eager apps that won't let disks spin down
- Tracker bug for applications waking up a lot
Monitoring / Auditing
Goal: Provide new tools to monitor / audit system usage to help user identify problematic applications, hardware or drivers.
Plan:
Dynamic adaptive tuning
Goal: Monitoring of system resources and adaptive tuning "on-the-fly" of affected components.
Project: tuned
Plan:
- Integration of ktune and tuned: Static vs. dynamic tuning parts + performance vs. power tuning options
- New monitoring and tuning plugin for CPUs (using PM-QOS for CPUs)
- New disk tuning algorithm for a more gradual tuning
- Fix for network tuning in combination with NM (grace period in NM for lost connections and/or mechanism in NM for changing device speeds)
Configuration
Problem: System tuning at the moment is too difficult.
Goal: Make it easier (obviously :) ).
Plan:
- Offer config tool with "profiles" which the user can switch to using a simple command line tool
- Allow creating, editing and deleting of profiles
- Offer comprehensive documentation of system tunables with examples and effects
