Sugov选定target frequency之后,需要通过cpufreq core(cpufreq framework)、cpufreq driver,cpu调频硬件完成频率的调整。cpufreq core是一个硬件无关的调频框架,集中管理了cpufreq governor、cpufreq driver、cpufreq device对象,同时提供了简单方便使用的接口API。 1 数据结构 1.1 struct cpufreq_diver数据结构 struct c...
-c, --cpu: 只显示逻辑CPU的信息,包括CPU编号、核心编号、线程编号等。 -x, --hex: 在显示CPU特性和标志时,以十六进制格式显示。 -y, --extended=KEY: 显示扩展的CPU信息。KEY可以是以下之一:cache,cpu,flags,topology。 -e, --online: 只显示在线的CPU的信息,即正在运行的CPU。 -V, --version: 显示...

In the world of operating systems, Linux has always been known for its high level of customization and flexibility. One of the key elements that users can customize in Linux is the CPU frequency, which can have a significant impact on performance and power consumption. ...

1cpufreq的背景 随着技术的发展,当前soc中的cpu主频一般都超过了1Ghz,而cpu的主频越高,其消耗的功耗也越大,这主要体现在以下两个方面: (1)cpu的运行频率越高,则晶体管在单位时间内的开关次数就越多,与其相关的动态功耗也越高。 (2)为了保证数字电路的逻辑正确,cpu运行频率越高,则其所需的供电电压也越高 ...
