I guess using -l 1000000000 is not enough to reach the benchmark itself
and you finish before bootup, that's why you observe the same behavior.
To create the checkpoint after boot, you need to run the script found in
configs/boot/hack_back_ckpt.rcS. Run it like this:
gem5.opt \
--outdir=a/directory/to/store/boot_ckpt \
configs/example/fs.py \
--kernel=...\
--disk-image=... \
--script=/configs/boot/hack_back_ckpt.rcS \
--cpu-type=AtomicSimpleCPU --num-cpus=1 --mem-size=...
You should have your checkpoint in the director you set with outdir.
To run from the checkpoint you need to use the following with your fs.py:
--checkpoint-dir=a/directory/to/store/boot_ckpt -r 1

Can you share the output from stdout and stderr? Also have you
checked system.terminal? There may be some clues of the error there as
well if the commands in the rcs script are not correct or you have any
missing dependencies in your disk image, for whatever reason.
You can also try to first generate simpoints etc for a simple program,
something like a simple loop in C, so that we can figure out if the
problem is in the SPEC or gem5.

I am not sure if this is possible in FS, at least not the same way
you do in SE. You will need to use simpoints in order to create
checkpoints for you code. After that you basically segment your
code into smaller, say 1000000 instructions per segment, which you
can run. Check the link I sent in my previous message. However
note that you will need to run the code for each benchmark twice,
once for generating the simpoint files and once to set the
checkpoints. For me this can take up to 4 week for the larger
codes, and a few days for the smaller ones in SPEC CPU 2017. Once
you have the checkpoints though, it should take a couple of hours.
I don't know if there is a faster way to do this, maybe someone else
has a better suggestion.

Hi,
Here is an example of an .rcs script. As Ciro told you, first you
need to have a bootable image, optionally create a checkpoint after
boot and finally add the benchmarks to the cd image.
#/bin/bash
cd
/your/path/SPEC_CPU_2017/benchspec/CPU/627.cam4_s/run/run_base_refspeed_aarch64-64.0000
/sbin/m5 dumpresetstats
/yourpath/SPEC_CPU_2017/benchspec/CPU/627.cam4_s/exe/cam4_s_base.aarch64-64
/sbin/m5 exit
In the example above you simply cd to the directory of the
benchmark you want to use and then run it. /sbin/m5
dumperesetstats resets your statistics counters and exit is used to
finish the execution. Note I use spec 2017, which I found that
it's best to run directly as I do above than use their
infrastructure. Problem is that FS is too slow and you waste a lot
of time running their python scripts. Also, I would encourage you
to learn about simpoints <http://gem5.org/Simpoints> if you plan on
running SPEC CPU 2006 with anything more than the test inputs.
Running with ref will take days/weeks.
Best,
Dimitrios Chasapis

The linked documentation runs an arbitrary benchmark of your choice.
You just have to add SPEC CPU to the image yourself as explained
there. I can't fully automate SPEC CPU build because it is closed source.

1. get Linux to boot, e.g.:
