[gem5-users] Re: Gem5 hang with multi core
Hi Xijing. I don't think anyone has gotten x86 and caches and locking/atomic instructions to fully work, so it's just a known bug in gem5 at the moment. If you want to simulate that sort of system, I would suggest using ARM if possible. We'd love to fix this at some point, but there are a lot of things to work on and only so many people to work on them :-/.

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.

Hi Xijing, Could you please provide us with more information (e.g. the command line) Kind Regards, Giacomo From: Xijing Han via gem5-users Sent: 26 March 2021 17:10 To: gem5-users@gem5.org Cc: Xijing Han Subject: [gem5-users] Gem5 hang with multi core Hi, I have a hang issue using gem5 with multi core mode.
