Hi Ayaz,
Thanks very much for your help. Like you said, I recompiled gem5 with
MESI_Two_Level and followed the instructions to compile the kernel 5.4. And I
tried both master branch and develop branch. But none of them work on my laptop
unfortunately. It always gets stuck at booting.
The command I run:
build/X86_MESI_Two_Level/gem5.opt configs/example/fs.py --kernel=vmlinux-5.4
--disk-image=ubuntu-18.img --num-cpus=2 --ruby --cpu-type=DerivO3CPU
Output:

And the output at the VM terminal:

!!!GET STUCK HERE!!!
Do you know what possible reasons? Thanks!
