The Linux Plumbers 2016 Power Management and Energy-awareness track focuses on topics related to power management frameworks, task scheduling in relation to power/energy optimization, and platform power management mechanisms. The goal is to facilitate cross framework and cross platform discussions that can help improve power and energy-awareness in Linux.
Topic proposals may relate to (but not restricted to):
Frequency/performance scaling (cpufreq).
CPU idle states (cpuidle).
Thermal management and scheduling under thermal constraints.
ACPI power management.
Device Tree representation of platform power management features.
Energy-aware scheduling decisions (minimize energy consumption).
Power domains management.
Integration of system-wide PM (system suspend etc) with runtime PM.
Measurement techniques and tools.
