Hi Muhammad, You don't have to use checkpoint. You can either use dumpreset stats or the m5_roi_begin/end magic instructions.
For how to change the config scripts... I encourage you to trace through the Python config scripts' execution in configs/. This will help you understand how the configuration and simulator execution works. You can use the Learning gem5 book: http://learning.gem5.org/ to get a solid foundation on how to write config scripts.
