Explore strategies for enhancing suspend/resume time and runtime power management on Android devices in this 15-minute conference talk from the Linux Plumbers Conference. Delve into the potential use of runtime PM and s2idle techniques to improve resume time, and examine common issues identified in the Android ecosystem. Analyze the impact of enforcing runtime PM by default for all devlinks created by fw_devlink, considering both benefits and drawbacks for vendors. Investigate methods for selective application of runtime PM to specific device links using fw_devlink. Address prevalent challenges encountered when enabling s2idle and discuss potential solutions to overcome these obstacles.
