Power management on modern hardware is quite complex. There are so many concepts and features provided by the hardware like frequency scaling, idle states, wakeup sources, sleep states, suspend-to-RAM, hibernation, etc! All this needs to be abstracted so kernel and user space code can properly manage power consumption. In this talk, we will deep dive into all these concepts, from the resources provided by the hardware to standard and portable software interfaces provided by the kernel and consumed by device drivers and user space applications, including tools and techniques to monitor and improve power consumption on an embedded Linux system.

This talk was presented at the Embedded Online Conference 2024:
