  16 # Test framework for GDB (remote protocol) using a "gdbserver",
  17 # ie. a debug agent running as a native process on the same or
  18 # a different host.
  19
  20 #
  21 # This module to be used for testing gdb with a "gdbserver"
  22 # built either from libremote or from gdb/gdbserver.
  23 #
  24
  25 #
  26 # To be addressed or set in your baseboard config file:
  27 #
  28 #   set_board_info gdb_protocol "remote"
  29 #       Unles you have a gdbserver that uses a different protocol...
  30 #
  31 #   set_board_info use_gdb_stub 1
  32 #       This tells the rest of the test suite not to do things
  33 #       like "run" which don't work well on remote targets.
  34 #
  35 #   set_board_info gdb,do_reload_on_run 1
  36 #       Unles you have a gdbserver that can handle multiple sessions.
  37 #
  38 #   set_board_info noargs 1
  39 #       At present there is no provision in the remote protocol
  40 #       for passing arguments.  This test framework does not
  41 #       address the issue, so it's best to set this variable
  42 #       in your baseboard configuration file.
  43 #       FIXME: there's no reason why the test harness couldn't
  44 #       pass commandline args when it spawns gdbserver.
  45 #
  46 #   set_board_info gdb,noinferiorio 1
  47 #       Neither the traditional gdbserver nor the one in libremote
  48 #       can presently capture stdout and relay it to GDB via the
  49 #       'O' packet.  This means that tests involving printf will
  50 #       fail unles you set this varibale in your baseboard
  51 #       configuration file.
  52 #
  53 #   set_board_info gdb,no_hardware_watchpoints 1
  54 #       Unles you have a gdbserver that supports hardware watchpoints.
  55 #       FIXME: gdb should detect if the target doesn't support them,
  56 #       and fall back to using software watchpoints.
  57 #
  58 #   set_board_info gdb_server_prog
  59 #       This will be the path to the gdbserver program you want to test.
  60 #       Defaults to "gdbserver".
  61 #
  62 #   set_board_info sockethost
  63 #       The name of the host computer whose socket is being used.
  64 #       Defaults to "localhost".  Note: old gdbserver requires
  65 #       that you define this, but libremote/gdbserver does not.
  66 #
  67 #   set_board_info gdb,socketport
  68 #       Port id to use for socket connection.  If not set explicitly,
  69 #       it will start at "2345" and increment for each use.
  70 #
  71
  72 # The guts live in gdbserver-support.exp now.
