current CPU frequency: 400 MHz (asserted by call to kernel) boost state support: Supported: yes Active: yes “` 在上面的输出中,`current CPU frequency`显示的是当前CPU的频率。 3. cat /proc/cpuinfo命令:执行命令`cat /proc/cpuinfo`可以查看详细的CPU信息,包括频率等。在输出中,`cpu MHz`字段显示...
current CPU frequency: Unable to call hardware analyzing CPU 1: … “` 以上就是在Linux系统中查看CPU频率的两个常用命令。 在Linux系统中,可以使用多个命令来查看CPU频率。 1. lscpu命令:通过lscpu命令可以查看各个CPU核心的频率。在终端中输入lscpu即可运行该命令。其中输出的结果中的CPU MHz字段显示了每个核心...
CPU频率调节器驱动是一个设备驱动程序,它与CPU频率调节器协同工作,以实现CPU频率的调整。CPU频率调节器驱动可以通过/sys/devices/system/cpu/cpuX/cpufreq目录下的文件来调整CPU的频率。cpuX表示CPU的编号,cpufreq目录下的文件包括scaling_governor、scaling_setspeed、scaling_cur_freq等,这些文件可以用来设置CPU的调频...
