А теперь включим шлюх и блекджек.

начиная с версии 7 gdb умеет питон — воспользуемся этим:
-------------

python

class InitRoutine (gdb.Command):

  """Initialize fiop debugging; parameters: <kernel path> <fiop module path>"""

  def __init__ (self):

    super (InitRoutine, self).__init__ ("initfiop",gdb.COMMAND_NONE,gdb.COMPLETE_FILENAME)

    super (InitRoutine, self).dont_repeat()

  def invoke (self, arg, from_tty):

    names=arg.split( )

    loadkernel="symbol-file %s"%(names[0])

    print "command:%s\n"%loadkernel

    gdb.execute(loadkernel)

    main=gdb.parse_and_eval("&modules")

    stext=0

    sdata=0

    sbss=0

    y=main['next'];

    while (str(y) != str(main)):

      x=gdb.parse_and_eval("((struct module *)(((char*)%s)-8))"%str(y))

      print "mod %s @ %s"%(x['name'].string() ,str(x))

      if (x['name'].string()=="fiop"):

        sa=x['sect_attrs']

        print "\tprocessing %i sections..."%sa['nsections']

        attrs=sa['attrs']

        for sidx in range(sa['nsections']):

          seg=attrs[sidx]

          print "\t\t%s @ %s"%(seg['name'].string(),str(seg['address']))

          if (seg['name'].string()==".text"):

            stext=str(seg['address'])

          if (seg['name'].string()==".data"):

            sdata=str(seg['address'])

          if (seg['name'].string()==".bss"):

            sbss=str(seg['address'])

        break

      y=y['next']

    if (stext != 0):

      loadfiop="add-symbol-file %s %s -s .data %s -s .bss %s"%(names[1],stext,sdata,sbss)
