As a powerful development platform, Visual Studio has provided many debugging methods. However, these debugging methods are relatively stuck on the surface. They are nothing more than setting breakpoints, viewing variables, and calling the stack

First, let's talk about how this problem came about. (When analyzing a technology, we should first consider what problems it wants to solve, or when learning new knowledge, what is the purpose of this knowledge ). When compiling the kernel, I
