Linux调度新特性EAS
Energy Aware Scheduling(EAS)EAS赋予调度器新的功能,使其能预测其调度决策(Task Placement)于CPU的能量消耗带来的影响,即Energy Aware。它依赖于CPU能量模型(Energy Model),以此来实现在确保性能影响最小的情况下为每个任务选择能量最优的CPU的调度决策。该特性主要由Linaro和ARM共同开发,在Linux Kernel 5.0版本正式发布。事实上EAS的开发过程经过了漫长的讨论和版本变迁,每个阶段的功能实现首先发生在Android原创 2020-07-26 16:42:26 · 2865 阅读 · 0 评论 -
