Adding Runtime Power Management Capabilities to Device Drivers
Offered By: Linux Foundation via YouTube
Course Description
Overview
Explore the intricacies of Runtime Power Management (RPM) in device drivers through this informative conference talk. Gain insights into the RPM subsystem, its callback functions, and the reference counting process. Learn about power management through the SysFS interface and discover important helper functions using the LTRF216A light sensor driver as an example. Understand how implementing RPM support can significantly reduce power consumption by putting devices into low-power states during idle periods without affecting user experience. Delve into the complexities of this framework, which has challenged developers since its introduction in 2009, and acquire practical knowledge to enhance your device driver development skills.
