Power saving has always been a major preoccupation in embedded systems, as by definition, they could have energy constraints. As embedded systems become increasingly pervasive, from IoT devices to industrial controllers, power efficiency is more critical than ever. This talk is aimed at developers, system integrators, and Linux enthusiasts. Whether you’re optimizing a battery-powered board or a power sensitive industrial board, you’ll walk away with practical insights and actionable tools. This talk will explore how to reduce electrical consumption on an embedded Linux system by leveraging software techniques such as kernel low power state (Suspend-To-RAM, Suspend-To-Disk), devices management. We’ll cover how to disable unused peripherals or scale CPU and DDR frequencies
