Hi,
I think that the best solution to your problem is to use a checkpoint. You can use the library m5op.h in util/m5/ to call the function m5_checkpoint(...) from the code you are simulating (assuming it's C or C++) and take a checkpoint once you get to your region of interest. Then you just need to restore that checkpoint using the CPU you want to use. Hope this helped, Ferran O.
