With GDB, Emacs uses the marker ^Z^Z to parse the file and line number:

(gdb) b main

(gdb) r

(gdb)

kgdb should output something similar. However, I guess the kernel in your
case is already running, so maybe it's a bit like attaching to a process
and perhaps the f irst marker is missing.

now what you meant by gdb-many-windows

and I dont think its got anything to do with
source code display, eg in my case even

and when I do a "n" the current source where the break
hit was displayed. and like in other emacs instances

opened in a seperate window if it is not already
opened.
