KGDB: automatic loading of modules in gdb

KGDB: automatic loading of modules in gdb

[Amit S. Kale]

Hi,

I have integrated a couple of kgdb features from TimeSys Linux distribution.

1.  Automatic loading of module files in gdb:
A special version of gdb is provided with this feature. It can detect loading 
and unloading of modules in a kernel. Whenever a module is loaded, gdb loads 
the module object file and makes it available for debugging. loadmodule.sh 
script is no longer needed.

2. Better kernel stack traces:
Kernel stack traces stop at entry points into the kernel and few invalid stack 
frames appear in gdb kernel backtraces, if any.

These features are available in kgdb-1.9 at http://kgdb.sourceforge.net

Have you or TimeSys, oh, I don't know, considered sending information
about this feature to the GDB developers so that KGDB does not require
a custom version of the GDB client?

I am going to be sending these patches to gdb developers also for 
review/feedback. I'll work on this feature myself for gdb.
