x86 linux boot is a component of the '--length long' regression. You need the kernel and disk image that are installed when the regression is run. command line: ./build/X86/gem5.opt ./tests/gem5/x86-boot-tests/run_exit.py --kernel boot-test/vmlinux-4.19.83 --disk boot-test/base.img --cpu-type

I'm planning to give this a shot, but is there a simple command line for this? It would take a lot of time to set up a system and all that, and it would be much nicer to just fire off, for instance, a linux boot test if we already have something lying around. Gabe On Wed, Oct 7, 2020 at 10:41 AM

I think Linux boot is pretty reasonable. Or, Linux boot + some multithreaded tests (parsec is available for x86 in gem5-resources). If there isn't much performance impact there, I think that would be strong evidence for little performance impact, generally. Cheers, Jason On Mon, Oct 5, 2020 at
