http://kernel.meizu.com/linux-process-stop.html 在调试内核的时候,经常会碰到几个相近的概念:进程 stop、进程 park、进程 freeze。这几个名词看起来都是停止进程,那么他们之间的区别和应用场景在分别是什么呢?下面就来分析一番。 本文的代码分析基于 Linux kernel 3.18.22,最好的学习方法还是 “RTFSC” 1. ...
When a process misbehaves, you might sometimes want to terminate or kill it. In this post, we'll explore a few ways to terminate a process or an application from the command line as well as from a graphical interface, usinggeditas a sample application. Using the command line/termination c...
Signalling in Linux can be done with "kill" (man kill for the available signals), you'd need the process ID to do that. (ps ax | grep java) or something like that, or store the process id when the process gets created (this is used in most linux startup files, see /etc/init.d...

学习地址(腾讯课堂):Linux内核源码/进程管理/内存管理/网络协议/设备驱动/文件系统 kthread_run实际是一个宏定义,它由kthread_create()和wake_up_process()两部分组成,调用了kthread_create后执行了wake_up_process.这样的好处是用kthread_run()创建的线程可以直接运行,使用方便。
Apart from restarting the computer, I had success bringing some processes out of the D state by flushing linux VM caches: kill -9 {process_id} sync echo 3 | sudo tee /proc/sys/vm/drop_caches This did not seem to affect system stability, but I'm not a systems programmer and not su...
Stop or suspend a running process in Linux January 5, 2011 Introduction If you start a process on a terminal, being it local or a remote (ssh) terminal, you normally loose the control of the terminal while the process is running, then if you want to recover that control, you have some...
