# Test framework for GDB (remote protocol) using a "gdbserver",

# ie. a debug agent running as a native process on the same or

# a different host.

#

# This module to be used for testing gdb with a "gdbserver"

# built either from libremote or from gdb/gdbserver.

#

#

# To be addressed or set in your baseboard config file:

#

#   set_board_info gdb_protocol "remote"

#       Unles you have a gdbserver that uses a different protocol...

#

#   set_board_info use_gdb_stub 1

#       This tells the rest of the test suite not to do things

#       like "run" which don't work well on remote targets.

#

#   set_board_info gdb,do_reload_on_run 1

#       Unles you have a gdbserver that can handle multiple sessions.

#

#   set_board_info noargs 1

#       At present there is no provision in the remote protocol

#       for passing arguments.  This test framework does not

#       address the issue, so it's best to set this variable

#       in your baseboard configuration file.

#       FIXME: there's no reason why the test harness couldn't

#       pass commandline args when it spawns gdbserver.

#

#   set_board_info gdb,noinferiorio 1

#       Neither the traditional gdbserver nor the one in libremote

#       can presently capture stdout and relay it to GDB via the

#       'O' packet.  This means that tests involving printf will

#       fail unles you set this varibale in your baseboard

#       configuration file.

#

#   set_board_info gdb,no_hardware_watchpoints 1

#       Unles you have a gdbserver that supports hardware watchpoints.

#       FIXME: gdb should detect if the target doesn't support them,

#       and fall back to using software watchpoints.

#

#   set_board_info gdb_server_prog

#       This will be the path to the gdbserver program you want to test.

#       Defaults to "gdbserver".

#

#   set_board_info sockethost

#       The name of the host computer whose socket is being used.

#       Defaults to "localhost".  Note: old gdbserver requires

#       that you define this, but libremote/gdbserver does not.

#

#   set_board_info gdb,socketport

#       Port id to use for socket connection.  If not set explicitly,

#       it will start at "2345" and increment for each use.

#

# The guts live in gdbserver-support.exp now.
