kdb source level debugging

hi

I am interested in implementing source-level debugging features for kdb. I know that kgdb already does that, but kgdb is very inconvenient to use compared to kdb as it requires two systems. Adding source level debugging to kdb would allow me to understand the kernel source code much better, since i would be able to trace thru the code and see it in action.

has any such work already been done before? any tips on how this can be implemented??

Thanks in Advance
