- - How can I debug loadable modules at run time?

Here is my way:

  ( /tmp/mymodule.ko exists on both [Host] and [UML] )
  + [Host] # gdb linux
  + [Host] (gdb) ...
  + [Host] (gdb) r <params>
  + [UML] # insmod /tmp/mymodule.ko
  + [UML] # cat /sys/module/mymodule/sections/{.text,.bss,.data}
  + [Host] (gdb) add-symbol-file /tmp/mymodule.ko <.text_addr> -s .bss
<.bss_addr> -s .data <.data_addr>
  + ...

Tell me if I was wrong, thanks!

- - How can I set breakpoint at module's init function?

After add module's symbol, I set breakpoint at init function then
'rmmod' then re-'insmod' but gdb didn't break at init function. What was
wrong?

- - Sometimes gdb can't follow source codes in '.h' header files. Did I
miss something?

Thanks in advance,
Mikado.
