gem5-X is a fork of gem5, which as far as I can tell, diverged from gem5 in the middle of 2018. gem5art was built on a version of gem5 in 2020-2021. While I can't say anything for certain, I wouldn't be surprised if you run into some difficulties getting this all to work perfectly.
Are you going to use ARM? We do provide NPB images, and linux kernels, but they work with X86. If you're set on using ARM you'll need to make your own. Instructions on building kernel for gem5 can be found here: https://gem5.googlesource.com/public/gem5-resources/+/refs/heads/stable/src/linux-kernel/, and info on creating a disk image containing NPB can be found here: https://gem5.googlesource.com/public/gem5-resources/+/refs/heads/stable/src/npb/. Please be careful with these as they are written assuming compilation to X86. While I'm sure you can create an ARM Linux kernel fairly easily, I'm not sure about NPB. I've simply never tried this. If X86 is an option, we provide a disk image and kernel: http://dist.gem5.org/dist/v21-2/kernels/x86/static/vmlinux-5.4.49 http://dist.gem5.org/dist/v21-2/images/x86/ubuntu-18-04/npb.img.gz [Note: GZIPPED] If you're looking for configuration files that (should) work with NPB, checkout gem5-resources at v21.1.0.2 : `git clone -b v21.1.0.2 https://gem5.googlesource.com/public/gem5-resources` and look at the configs provided under `src/npb`. That will definitely give you something to start with. -- Dr. Bobby R.
