Can you try this command line: ./build/X86/gem5.opt configs/example/fs.py --cpu-type=DerivO3CPU --caches --disk-image=(point to ur disk) --kernel=(point to ur kernel)
And try a new image and kernel. For e.g., you can try to use Parsec image x86 image to test if that works or not. (x86 image: http://www.cs.utexas.edu/~cart/parsec_m5/) Best regards, Abhishek On Tue, Mar 5, 2019 at 2:46 PM Sethu Jose <sethuj...@gmail.com> wrote: > Hi Abhishek, > > I tried the baseline system without the L2 cache.
