Two machines are required for using kgdb. One of these machines is a development machine and the other is the target machine. The kernel to be debugged runs on the target machine. The development machine runs an instance of gdb against the vmlinux file which contains the symbols (not boot ...

Be sure to include the -g option during compilation in order to enable debugging symbols for gdb. Copy the compiled object code to the target machine. Install the object code into the kernel using insmod's -m parameter: insmod -m simple.o This, of course, loads the module and produces...

symbols by name in kernel built-ins or in kernel modules if the code was built with CONFIG_KALLSYMS. Kgdb is intended to be used as a source level debugger for the Linux kernel. It is used along with gdb to debug a Linux kernel. The expectation is that gdb can be used to "break ...
