Hello Please As I am trying to run X86 FS from a long time and i am blocked So I have some questions: Do you type any commands (e.g. for mounting the disk image) before starting booting (build/X86/gem5.opt configs/example/fs.py --kernel=x86_64-vmlinux-2.6. 22.9.smp --cpu-type=detailed --l2cache --caches --script=run.sh -n 4)?
What is script =run.sh ?is it a script you wrote it ? What is the command used to run hello.c as i tried as shown "build/x86/gem5.opt configs/example/fs.py -c /tests/test-progs/hello/bin/x86/linux/hello -n1" but it failed ? Please your answer may support me a lot in my blocking problem. Thank you in advance for time.
