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. Thanks
