Dear Jason,

I removed --cache --l2cache arguments and replaced it with --ruby. Then ran
simulation for MOESI_CMP_Directory and MOESI_CMP_Token. But then also i got
the same configuration (compared config.ini). Please help.

./build/ARM/gem5.opt -d m5out/bbench1mb configs/example/fs.py
--kernel=vmlinux.smp.ics.arm.asimbench.2.6.35
--disk-image=ARMv7a-ICS-Android.SMP.Asimbench-v3.img --frame-capture -n 4
*--ruby* --l1d_size=64kB --l1d_assoc=4 --l1i_size=64kB --l1i_assoc=4
--l2_assoc=16 --l2_size=1MB --mem-size=256MB --cpu-type=DerivO3CPU
--cpu-clock=2.8GHz --machine-type=RealView_PBX --mem-type=LPDDR3_1600_x32
--script ~/asimbench/asimbench_boot_scripts/bbench.rcS

This is the command i used to start FS simulation.

Regards,

Midhun P
