Generating DA monitor and generating container requires different parameters. This is implemented by peeking at sys.argv and check whether "--container" is specified, and use that information to make some parameters optional or required. This works, but is quite hacky and ugly. Replace this hack with Python's built-in subparsers. The old commands: python3 dot2/dot2k -d wip.dot -t per_cpu python3 dot2/dot2k -n sched --container are equivalent to the new commands: python3 dot2/dot2k monitor -d wip.dot -t per_cpu python3 dot2/dot2k container -n sched Reviewed-by: Gabriele Monaco Signed-off-by: Nam Cao --- tools/verification/dot2/dot2k | 37 +++++++++++++++++--------------- tools/verification/dot2/dot2k.py | 2 +- 2 files changed, 21 insertions(+), 18 deletions(-) diff --git a/tools/verification/dot2/dot2k b/tools/verification/dot2/dot2k index 767064f415e7..133fb17d9d47 100644 --- a/tools/verification/dot2/dot2k +++ b/tools/verification/dot2/dot2k @@ -13,30 +13,33 @@ if __name__ =3D=3D '__main__': import argparse import sys =20 - def is_container(): - """Should work even before parsing the arguments""" - return "-c" in sys.argv or "--container" in sys.argv - parser =3D argparse.ArgumentParser(description=3D'transform .dot file = into kernel rv monitor') - parser.add_argument('-d', "--dot", dest=3D"dot_file", required=3Dnot i= s_container()) - parser.add_argument('-t', "--monitor_type", dest=3D"monitor_type", req= uired=3Dnot is_container(), - help=3Df"Available options: {', '.join(dot2k.monit= or_types.keys())}") - parser.add_argument('-n', "--model_name", dest=3D"model_name", require= d=3Dis_container()) parser.add_argument("-D", "--description", dest=3D"description", requi= red=3DFalse) parser.add_argument("-a", "--auto_patch", dest=3D"auto_patch", action=3D"store_true", required=3DFalse, help=3D"Patch the kernel in place") - parser.add_argument("-p", "--parent", dest=3D"parent", - required=3DFalse, help=3D"Create a monitor nested = to parent") - parser.add_argument("-c", "--container", dest=3D"container", - action=3D"store_true", required=3DFalse, - help=3D"Create an empty monitor to be used as a co= ntainer") + + subparsers =3D parser.add_subparsers(dest=3D"subcmd", required=3DTrue) + + monitor_parser =3D subparsers.add_parser("monitor") + monitor_parser.add_argument('-n', "--model_name", dest=3D"model_name") + monitor_parser.add_argument("-p", "--parent", dest=3D"parent", + required=3DFalse, help=3D"Create a monitor= nested to parent") + monitor_parser.add_argument('-d', "--dot", dest=3D"dot_file") + monitor_parser.add_argument('-t', "--monitor_type", dest=3D"monitor_ty= pe", + help=3Df"Available options: {', '.join(dot= 2k.monitor_types.keys())}") + + container_parser =3D subparsers.add_parser("container") + container_parser.add_argument('-n', "--model_name", dest=3D"model_name= ", required=3DTrue) + params =3D parser.parse_args() =20 - if not is_container(): - print("Opening and parsing the dot file %s" % params.dot_file) try: - monitor=3Ddot2k(params.dot_file, params.monitor_type, vars(params)) + if params.subcmd =3D=3D "monitor": + print("Opening and parsing the dot file %s" % params.dot_file) + monitor =3D dot2k(params.dot_file, params.monitor_type, vars(p= arams)) + else: + monitor =3D dot2k(None, None, vars(params)) except Exception as e: print('Error: '+ str(e)) print("Sorry : :-(") @@ -45,7 +48,7 @@ if __name__ =3D=3D '__main__': print("Writing the monitor into the directory %s" % monitor.name) monitor.print_files() print("Almost done, checklist") - if not is_container(): + if params.subcmd =3D=3D "monitor": print(" - Edit the %s/%s.c to add the instrumentation" % (monitor= .name, monitor.name)) print(monitor.fill_tracepoint_tooltip()) print(monitor.fill_makefile_tooltip()) diff --git a/tools/verification/dot2/dot2k.py b/tools/verification/dot2/dot= 2k.py index 0922754454b9..9ec99e297012 100644 --- a/tools/verification/dot2/dot2k.py +++ b/tools/verification/dot2/dot2k.py @@ -19,7 +19,7 @@ class dot2k(Dot2c): monitor_type =3D "per_cpu" =20 def __init__(self, file_path, MonitorType, extra_params=3D{}): - self.container =3D extra_params.get("container") + self.container =3D extra_params.get("subcmd") =3D=3D "container" self.parent =3D extra_params.get("parent") self.__fill_rv_templates_dir() =20 --=20 2.39.5
