Hi,I am trying to pass a boolean as one of the params to the BaseCPU class from the Options.py file. I have declared my boolean in the Options.py file as parser.add_argument('--defense', action="store_true", default=False, help="Enable defense") so that I could enable or disable from the cmd line. In the BaseCPU.py file, I have added the boolean to pass to the BaseCPU class defense = Param.Bool(False, "Whether to use Defense") Finally, in the base.cc file in the constructor for BaseCPU, I used params().defense and p.defense, but the value never changes to True. It's always False. Command to run Gem5 with my passed argument run configs/example/se.py --cmd tests/test-progs/hello/bin/arm/linux/hello --mem-size=4GB --cpu-type=DerivO3CPU --cpu-clock 2GHz --sys-clock 2GHz --l1d_size 32kB --l1d_assoc 8 --l1i_size 32kB --l1i_assoc 8 --l2_size 2MB --l2_assoc 16 --l2cache --caches --defense I am not sure what I am doing wrong.
I wonder if the actual name of the parameter is something like system.cpu[0].defense. You can check the config file that a run dumps out to see. (The [0] is something I discovered on my own to be necessary, even in a system with only one cpu; it's because there is an underlying vector.) You could try: --param "system.cpu[0].defense=True" Or something like it. There's probably a way to get a top-level new parameter like --defense to work, but at some point, some piece of code has to pass it on to the actual component. A given component will ignore parameters that do not match its name ...
