Linux内核函数调用关系的验证方法

A way to verify running Linux Kernel function

作为最流行的开源操作系统,Linux在各行各业得到了广泛的应用。因此了解Linux内核的架构及工作机制就显得非常重要。然而目前对Linux内核的主要学习途径是各种教科书以及经验博客,而对于Linux内核的实时动态监控技术却很少有人了解。本文提供一种动态监视内核运行过程的方法。通过此方法可以动态地观察Linux内核的函数调用情况,以及CPU寄存器值等动态信息。

As the most popular open source operating system, Linux has been widely used in many fields. For a better apply to the Linux industry, understanding the Linux Kernel structure and working mechanism is very important. However, currently for the Linux Kernel learner, the main way is through various textbooks and lessons blog. There is barely way for the Linux Kernel real-time dynamic monitoring. This article provides a dynamic method to monitor the running Linux Kernel. By using this method, we can dynamically observe Linux Kernel function calls, as well as dynamic information such as CPU register values.
