I don’t know exactly how you are figuring out the warm-up period and how this all this is to fit together but the following may be of help:
If you’re using the gem5 standard library the “simulator” module has a function called “schedule_max_insts”. It will exit the simulation loop when any thread in any core reaches the specified number of instructions. If you're not using the standard library you can set the BaseCPU’s “max_insts_any_thread” parameter prior to the system’s initialization specify when to exit the simulation, or, if after initialization, BaseCPU’s “scheduleInstStopAnyThread” function can be used. -- Dr. Bobby R.
