摘要

基于动态电压和频率缩放(DVFS)的节能技术可以优化处理器的性能，使其能够在越来越节能的工作模式下运行。本文提出了一种新的基于dvfs的Linux内核CPU性能自调优控制器设计。控制器自动适应当前观察到的CPU负载动态模型，调整CPU性能水平以补偿负载变化，同时优化已执行操作的能源效率。

Fixed-point self-tuning CPU performance controller for Linux kernel

Power saving techniques based on dynamic voltage and frequency scaling (DVFS) allow to optimize performance of processors capable of operating in more and more energy-efficient operating modes. In this paper we propose a new design of DVFS-based self-tuning CPU performance controller for the Linux kernel. The controller autonomously adapts to currently observed model of CPU load dynamics and adjusts CPU performance level to compensate for load variations while optimizing energy efficiency of performed operations.
