For the old one, I use: build/X86_SE/m5.fast configs/example/cmp.py -F 20000000 --maxtick 10000000000 -d --caches --l2cache -b h264_sss --prog-interval=1000000
for the new one I use: build/X86/m5.fast configs/example/cmp.py --cpu-type=detailed -F 20000000 --maxtick 10000000000 --caches --l2cache -b h264_sss --prog-interval=1000000 I attached the configs and stats.
