Utilization Clamping in CFS - Fairness, Latency, and Energy Efficiency

Explore the concept of utilization clamping in the Completely Fair Scheduler (CFS) and its impact on fairness, latency, and energy efficiency in this 17-minute conference talk from the Linux Plumbers Conference. Learn how uclamp enables user-space to set performance and efficiency preferences for individual tasks and task groups, with a focus on its current implementation in Android systems. Delve into the discussion aimed at aligning expectations, use-cases, and potential implementations of uclamp in upstream Linux. Gain insights from speakers Dietmar Eggemann and Morten Rasmussen as they address the challenges and opportunities in integrating this feature effectively.
