Hi Dr. Bruce, Thanks a lot for the reply.
Setting the variable this way works, but only if I set it before the simulation starts completely. I looked at the source code and it seems max_insts_any_thread is only used to schedule an exit event in the BaseCPU::init() function. I’m guessing this is only called once at the very beginning. Is there a way to set the max instruction count when the simulation has exited (e.g., due to an m5 exit instruction) so that it runs for n instructions after this point?
