Yes you can. Generally the preferred way to run is to boot/start a benchmark with the atomic CPU and then drop a checkpoint. You can then restore from the checkpoint with the "detailed" CPU.
Simple use case: 1) specify gem5 command with "--checkpoint-at-end" and the atomic CPU 2) Once the benchmark/boot gets to the place you desire kill the simulation (CTRL-C). This creates a checkpoint 3) Restore from the checkpoint with the detailed CPU (specify the desired cpu model and also "-r1" to restore from the checkpoint) On Tue, Sep 2, 2014 at 3:20 PM, Prathap Kolakkampadath via gem5-users < gem5-users@gem5.org> wrote: > Hi Users, > > I am trying to run some benchmarks on ARM detailed cpu.
