Hi everyone
I'm relatively new to the concept of fast-forwarding. But from what I understand is that you can cause gem5 to switch CPU models to a more detailed one after a certain number of instructions have been simulated using the first CPU. I have a region of interest in my source code and I want to switch CPUs as soon as the first line of that code starts executing because it takes 3 hours to reach it currently just using the DerivO3CPU. So how do I know/find out how many instructions I need to run the first CPU for before switching to the more detailed CPU? Thanks
