Linux kernel debugging methods KDB: Only in the assembly code level for debugging; The advantage is that two machines are not required for debugging. GDB: When debugging a module, it lacks some vital features that can be used to view the operation

For anyone who writes the kernel code, one of the most attractive issues is how to complete the debugging. Because the kernel is a function set not related to a process, its Code cannot be easily put in the debuggerAnd cannot be tracked. This

"Kernel symbol table, kernel symbol table" Linux's kernel is a single kernel monolithic, and any function can access public data structures and function calls. In the design of the program, you need to name some function names, variable names, and
