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. Then when i change the benchmark i should just modify the disk image, and run again gem5 resuming the simulation from the checkpoint. The checkpoint part worked fine, gem5 resumes just aftre the boot. The problem is that the disk image is not changing, even if i have mounted the image, deleted a file and put a new one inside. When i boot the system i still see the old file. It is frustrating to wait the whole boot for each benchmark i run. I have also tried to disable the COW image, and gem 5 is directly working on the raw disk image. Am i doing something wrong? Can you give me some help? Even a different method to dynamically modify the disk image is welcome.
