RE: Using Python to infer some internal data
I agree. It uses add-symbol-file to add symbols for loadable modules. I
thought my code should use add-symbol-file (or underneath functions). My
concern here is
- Is there its counter part for Linux kernel?
- Is the code which break-in kernel when gdb is starts valuable? Before gdb
is started for Linux kernel, we have to type Ctrl+Alt+SysRq and g to break
in to kernel. My code sends BREAK and g to kernel through serial port to
break in. This code is mine and 16 lines.

Tom will be able to give you a more definitive answer - but mine is
that I don't think either is possible yet, but both of these are on
my list of original goals for scripting support.

Caz, I've copied you because what Andrew's done here is very close to
what you posted for Linux KGDB - but done entirely in Python
scripting. Once we get the breakpoint issue resolved, I think this is
a much nicer way to handle Linux loadable modules too.
