Hi Ciro, Sorry for the late response. I had a lot of trouble setting up linux kernel module on my server. Indeed it works there.
But I have added NVMain with gem5 on my system. So I was hoping if can fix this issue on my setup. I am still trying to figure out why it keeps on failing. My gem5 version is a mercurial directory.

Which disk image / kernel are you using? I have produced a working fs.py aarch64 example at: https://github.com/cirosantilli/linux-kernel-module-cheat/tree/singh-mm#gem5-getting-started (use the singh-mm branch I've created) Build and run with: ./configure -g && ./build -a aarch64 -g && ./run -a aarch64 -c 4 -g -- --cpu-type=TimingSimpleCPU which uses 4 cores and TimingSimpleCPU. After boot finishes, run your benchmark inside the guest with: /MM.out It completes without errors. The setup also worked on arm instead of aarch64, but my arm setup is running very slowly for some reason which I don't understand yet: https://github.com/cirosantilli/linux-kernel-module-cheat/tree/02b433e3ee8edb129c1e286a37ed2c8a8170fefe#benchmark-linux-kernel-boot so just use the aarch64 one if you can. You will also likely want to enable compiler optimizations as described at: https://github.com/cirosantilli/linux-kernel-module-cheat/tree/02b433e3ee8edb129c1e286a37ed2c8a8170fefe#enable-compiler-optimizations but I haven't tested it with that setup. > On running gem5 binary with --version option I get "Gem5.opt 2.0". > Please provide the actual git SHA from git log, --version is not updated often and therefore too imprecise. > I tried running a simple hello world program with se.py and got the > same error.
