# 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.
