# 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.
