Linux on ARMThe ARM Linux developers continue working on Energy Aware Scheduling (EAS) for the mainline Linux kernel to better handle systems with asymmetric CPU topologies, namely SoCs like those with ARM big.LITTLE cores.

Energy Aware Scheduling is designed to take into account information from the ARM Energy Model framework for making better scheduling decisions based upon the topology of the CPU cores with the performance and power characteristics. On ARM big.LITTLE systems EAS not only helped reduce energy usage by up to a few percent but also the performance in some workloads did improve by a percent or two.
