Open Source Summit + Embedded Linux Conference Europe 2020

Zephyr will provide new interfaces and APIs for power management which are designed to be conveniently adapted to different SOCs and architectures. Another goal of the new design is to consume as little power as possible in a given system state and don’t waste energy when idle. The power management components are classified into five categories: pm policy, pm core, platform pm, device pm, device runtime pm. Every layer has been well considered and designed, many new technologies have been used and the implementation is ongoing, it will be ready in early September. In this presentation, Wentong Wu, the maintainer of Zephyr power management, will provide as much technical detail as possible and the benefit of the new power management framework. And finally, the future technical plans of Zephyr power management will be presented and discussed.
