Energy-aware Scheduling and CPU Power Management track

Friday, October 17, 2014 from 9:00am – Noon
Room 26
 

The Linux Plumbers 2014 Energy-aware Scheduling and CPU Power Management track is focusing on energy-awareness improvements for the scheduler and cpu power management frameworks (cpuidle, intel_pstate, cpufreq).

Following last years micro conference (power-efficient_scheduling) and the Kernel Summit workshop last year a number of areas were identified which need work to move towards improved energy-awareness in the kernel. This aim of this micro conference is to coordinate and discuss efforts made in these and related areas.

More details about some of the energy-aware scheduling efforts are gathered here: Energy-aware Scheduling wiki-page

* The next event with the io latency tracking

The IO latency tracking allows to track per task the expected sleep time when blocked on an IO. Coupled with the next timer event, it gives an accurate information about the next event supposed to wake up a cpu (slides)
