linuxsys内核

是否可以通过Linux中的/ sys从特定内核获取当前的CPU使用率？

想编写一个shellscript来读取每个内核的当前CPU利用率。是否可以从/sysLinux（CentOS 8）中的目录中读取？我发现/sys/bus/cpu/drivers/processor/cpu0这确实给了我很多信息（例如当前频率），但是我还没有弄清楚如何读取CPU使用率。换句话说：是否有文件可以让我了解Linux中特定CPU内核（特别是CentOS 8）的当前利用率？

linux内核的syslets补丁

linux的系统调用及其丰富，但是却都是同步的，虽然2.6内核新增加了异步io，但是对于套接字等却以及非直接读写io却不可用，于是开发者就有了一个想法，既然一些任务可以由内核的xxlet或者内核线程（工作队列）来异步执行，比如tasklet，那么能否建立一套异步执行系统调用的机制呢？这就是syslets的由来。本文转自 dog250 51CTO博客，原文链接:http://blog...
