Thanks for the respond. This is my command line:
../gem5_security/gem5_noBWPQ/build/X86/gem5.opt --outdir=/home/xhan24/gem5_out_16G_new/gem5_out_redis_orig/latency_after_WPQ_noBWPQ ../try_config/configs/example/fs.py --checkpoint-dir=/home/xhan24/gem5_chk/multi_core/redis --disk-image=/home/xhan24/gem5_disk2/e_ext.img --kernel=/home/xhan24/gem5_kernel/KERNEL414 --mem-size=16GB --cpu-type=DerivO3CPU -n 4 --cpu-clock=1GHz --mem-type=DDR4_2400_16x4 --caches --l2cache --l3cache --cacheline_size=64 -r 1 --script redis_run.scr So when I start the multi core mode, it works fine for a while, then it got stuck in some kernel funcion: native_queued_spin_lock_slowpath, gem5 is still working, but it always execute the instructions in this function.
