I don't know what causes that problem, but here is a working setup: https://github.com/cirosantilli/linux-kernel-module-cheat/tree/0b9157c91912685b0c59773126e1c1fefc7eea84#gem5
After build, run: ./run -a aarch64 -g -c 4 and it boots correctly, and cat /proc/cpuinfo shows 4 cpus. The scripts there end up running the following gem5 command: M5_PATH='/home/ciro/bak/git/linux-kernel-module-cheat/out/aarch64/buildroot/build/gem5-1.0/system' \ '/home/ciro/bak/git/linux-kernel-module-cheat/out/aarch64/buildroot/build/gem5-1.0/gem5/build/ARM/gem5.opt' \ --debug-file=trace.txt \ -d '/home/ciro/bak/git/linux-kernel-module-cheat/out/aarch64/gem5/m5out' \ '/home/ciro/bak/git/linux-kernel-module-cheat/out/aarch64/buildroot/build/gem5-1.0/gem5/configs/example/fs.py' \ --disk-image='/home/ciro/bak/git/linux-kernel-module-cheat/out/aarch64/buildroot/images/rootfs.ext2' \ --kernel='/home/ciro/bak/git/linux-kernel-module-cheat/out/aarch64/buildroot/build/linux-custom/vmlinux' \ --mem-size='256MB' \ --num-cpus='4' \ --script='/home/ciro/bak/git/linux-kernel-module-cheat/data/readfile' \ --command-line='earlyprintk=pl011,0x1c090000 console=ttyAMA0 lpj=19988480 rw loglevel=8 mem=256MB root=/dev/sda console_msg_format=syslog nokaslr norandmaps printk.devkmsg=on printk.time=y' \ --dtb-file='/home/ciro/bak/git/linux-kernel-module-cheat/out/aarch64/buildroot/build/gem5-1.0/gem5/system/arm/dt/armv8_gem5_v1_4cpu.dtb' \ --machine-type=VExpress_GEM5_V1 \ On Sat, Apr 28, 2018 at 8:59 PM, Xin Zhan <zhanxin...@gmail.com> wrote: > Hi all, > > I try to simulate 4-core ARM processor in FS mode.
