Hi Christian,
This probably isn't exactly the answer you are looking for, but I wrote a tool that allows you to mount the host file system running gem5 (similar to /host in simics if you are familiar with that). If you're interested, you can try it out and see if it works for you. Git remotes and guide are here: https://github.com/abmerop/gem5fs https://bitbucket.org/mrp5060/gem5fs (I actually wrote this because I don't have sudo access on my university machine to mount disk images. But you can see if it solves this problem too.) -- Matt Poremba Ph.D. Candidate 354B IST Building Pennsylvania State University University Park, PA 16802 On Fri, Mar 28, 2014 at 5:56 AM, Christian Pinto <[email protected]>wrote: > Hi all, > > I am Christian Pinto, PhD student at university of Bologna. > > I am actually working on gem5-gpu, but i ran into a problem which i think > is strictly related to gem5. > > For my project i need to run different benchmarks on gem5-gpu, booting > linux on x86 64bit (the kernel is Linux x86_64-vmlinux-2.6.28.4-smp). > > Since the boot is quite long, i thought to take a checkpoint just after > the boot is completed.
