在介绍 ondemand governor 的具体实现之前,我们先来看一下如何使用 ondemand governor 及其向用户提供了哪些操作接口。通过 cpufreq-set 将 ondemand 设置为当前所使用的 governor 之后,在 /sys/devices/system/cpu/cpuX/cpufreq 目录下会出现一个名为 ondemand 的子目录 $ sudo cpufreq-set -g ondemand $ l...

sudo cpufreq-set -c 0 -g ondemand ``` 在这个命令中,-c 0表示设置第一个CPU的频率,-g表示指定使用的调频器类型,ondemand表示使用ondemand调频器。通过这个命令,用户可以快速地设置CPU的运行频率,以满足系统的实际需求。 除了使用cpufreq-set命令外,用户还可以通过cpufreq-info和cpufreqd等命令来查询CPU的频率...

It selects the maximum P-state it is allowed to use, subject to limits set via sysfs, every time the driver configuration for the given CPU is updated (e.g. via sysfs). This is the default P-state selection algorithm if the CONFIG_CPU_FREQ_DEFAULT_GOV_PERFORMANCE kernel configuration opt...
