Energy Aware Scheduling (EAS) in the Android Kernel: Concepts, Models, and Thread Selection
Energy Aware Scheduling (EAS) in the Android kernel uses the CPU energy model to select the most energy‑efficient CPU for each thread on heterogeneous big.LITTLE processors, considering capacity, OPP, power, and efficiency ratio; it migrates only if the migration saves more than 6% energy and overall CPU utilization stays below 80%, otherwise reverting to traditional load‑balancing.
