Hi Hoa,
Thanks for the follow-up.
Fortunately I was able to run a FS simulation using the provided fs.py
config file with the parsec.img. I found no errors and was even able to
run some SPLASH-2 benchmarks on it, simply using the --disk-image with
the provided --kernel was enough. Thanks for all the help you have
provided me with. Anyway I'll take a look at all the resources you've
provided me with to see if it can enhance my workflow.
Greetings,
Miguel Antonio Avargues Gutiérrez.

Hi Miguel,
Sorry for the late reply.
I don't know whether parsec.img would work with configs/fs.py;
however, we've been testing and using parsec.img with the gem5 configs
from gem5-resources
(https://gem5.googlesource.com/public/gem5-resources/+/refs/heads/stable/src/parsec/configs/)
[1].
You can modify the configs from [1] to run command line commands
(which, I guess, would have the same behaviors as --script from
configs/fs.py). Specifically, in the writeBenchScript() function in
run_parsec.py, the content inputted to bench_file.write() will
eventually be appended to .bashrc during gem5 simulation.
Since you mentioned newer Linux kernel versions, it is known that the
current state of the configs from [1] would run into a kernel panic
when running the simulation with newer Linux kernel versions. This
change (https://gem5-review.googlesource.com/c/public/gem5-resources/+/42261)
is supposed to fix the problem.

Thanks for the help Hoa.
I have downloaded the parsec.img disk image and the right kernel version
from [1]. It seems to boot properly when using the fs.py config script
but i don't get a terminal to interact with the simulated system using
telnet. Is that expected because i need to use the --script parameter or
am I missing something?

Hi Miguel,
For X86 full system simulation, specifically for creating custom disk
image that runs with newer Linux kernels, I believe gem5-resources has
the resources for that. More details can be found here,
- General introduction and artifacts:
https://www.gem5.org/documentation/general_docs/gem5_resources/ [1]
- Source code: https://gem5.googlesource.com/public/gem5-resources [2]
- Detailed instructions:
https://gem5art.readthedocs.io/en/latest/tutorials/boot-tutorial.html#creating-a-disk-image
[3] and
https://gem5art.readthedocs.io/en/latest/tutorials/npb-tutorial.html#creating-a-disk-image
[4]
- From link [1], you can find built disk images, which could be
manipulated to suite an experiment.
- From link [2], you can find examples of building disk images for
some benchmarks such as npb, parsec, gapbs and spec.
- Link [3] and link [4] offer some explanation of what happens when
the disk images are built. The same website
(https://gem5art.readthedocs.io/en/latest/) also has tutorials for
other benchmarks and there are outdated links to GitHub (which were
moved to [2]). We are working on updating the website.
Regarding compiling util/m5, the new command to compile it is
```
scons build/x86/out/m5
```
where "x86" could be replaced by other ISA.
I hope this helps.
Regards,
Hoa Nguyen

Hello everyone.
I'm a pretty new user to gem5 and I've been trying to get a FS
simulation going on with a newer kernel version and a custom disk image.
Unfortunately i feel like my disk image isn't properly created since i
can't get the simulation going. Is there any up-to-date tutorias about
making a custom file image? All the tutorias i've found make references
to files that i can't find in the simulator (such as
util/m5/Makefile.x86). I am using version 20.0.0.3 and I can't change
it.
