Using kgdb, kdb and the kernel debugger internals
Kgdb is a debug stub that allows another machine to connect a source-level debugger over a serial link.
kdb reuses kgdb's breakpoint and polled I/O infrastructure in
order to implement a machine-level kernel debugger that runs entirely
on the machine being debugged.
