Dear all, I wonder does anyone successfully run FS mode on ARM_MESI_Three_Level_HTM protocol? If so is it possible to share the gem5 version and the running command? I tried multiple versions and commands but it doesn't work and the details are below.
First, the newest gem5 v21 changes some stats collection part by running it generates stats initialization failure error. *Command&error*: > ➜ gem5 git:(stable) ✗ ./build/ARM_MESI_Three_Level_HTM/gem5.opt > ./configs/example/fs.py --ruby --num-cpus=1 --cpu-type=O3_ARM_v7a_3 > --disk-image=$M5_PATH/disks/linaro-minimal-aarch64.img > --kernel=./system/linux/vmlinux Global frequency set at 1000000000000 ticks per second > warn: No dot file generated.

I'm using the disk *linaro-minimal-aarch64.img* 2. I compiled gem5 via "python3 `which scons` CC=gcc CXX=g++ build/ARM_MESI_Three_Level_HTM/gem5.opt TARGET_ISA=arm PROTOCOL=MESI_Three_Level_HTM SLICC_HTML=True CPU_MODELS=AtomicSimpleCPU,TimingSimpleCPU,O3CPU -j 8" after the modifying *haveLSE *in *src/arch/arm/isa.cc* 3. I tried to build the kernel manually and download the prebuilt kernels. Best, Chris
