Use of Linux on battery-powered systems continues to grow, and general
energy-efficiency concerns are not going away any time soon. The Power
Management and Energy-awareness microconference therefore continues a
Linux Plumbers Conference tradition of looking into ways to improve
energy efficiency.

In spite of significant progress made over the last year on
multiple fronts, including but not limited to the enhancements of
the scheduler's load-tracking facility with an improved awareness of
the amount of time taken by realtime processes, deadline processes,
and interrupt handling in order to improve CPU performance scaling,
the work on implementing energy-aware scheduling on asymmetric systems
in the kernel [1], and the process utilization clamping patch series
[2], there still are open issues to be discussed and new ideas to
consider. This year, the focus is on energy-optimized task scheduling,
user space interfaces for passing power/performance hints to the
kernel, platform power management mechanisms and power management
frameworks.

Specific topics include energy-aware scheduling, per-task
and per-cgroup performance hints, timer granularity issues in the
runtime PM framework, generic power domains (genpd) framework
enhancements, firmware-based and direct control of low-level power
management features of computing platforms, a proposed on-chip
interconnect API, and improving selection of CPU idle states.

We hope to see you there!

LPC [3] will be held in Vancouver, British Columbia, Canada from
Tuesday, November 13 through Thursday, November 15.
