The simpoints taken for SPEC CPU 17 are far from the beginning. So, in order to be able to take simpoint in a reasonable time frame, I am using the KVM CPU:1) Boot with KVM and taking a checkpoint2) Running the application with simpoints information as input with KVM CPU and taking the simpoints3) Restoring from simpoint with different cpus. If I use the following command line, the warm up and real simulation will be done: --restore-with-cpu=DerivO3CPU --cpu-type=AtomicSimpleCPU restore-simpoint-checkpoint --checkpoint-dir=./simpoints/605.mcf/ -r 1
However, as far as I know, with have to restore from Simpoint with the exact CPU that we have taken our Simpoints, in this case, KVM. So, I tried to restore with the following command: --restore-with-cpu=DerivO3CPU --cpu-type=X86KvmCPU restore-simpoint-checkpoint --checkpoint-dir=./simpoints/605.mcf/ -r 1 Initially, the simulator complained about indirect branch predictor. Because the default indirect branch predictor is not None. After solving that problem, simulation freezes and make no progress. Also, I checked different combinations for restore-with-cpu and cpu-type, and went through the Simulation.py and fs.py, nut still do not know hwo I should restore from simpoints.
