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 Dimitrios, I appreciate your help. How I can run the benchmark for
one million instruction in the FS mode. In SE mode I used -I 1000000 .
Any help would be appreciated. Best Regards

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.

Subject: Re: [gem5-users] Run CPU 2006 benchmark on gem5 fs mode
1. get Linux to boot, e.g.:
https://github.com/cirosantilli/linux-kernel-module-cheat/tree/657c59249e56d861bb0a437a1b1c757797281910#gem5-buildroot-setup
2. learn to checkpoint at the end of boot, restore, and run an
executable afterwards, e.g.:
https://github.com/cirosantilli/linux-kernel-module-cheat/tree/657c59249e56d861bb0a437a1b1c757797281910#gem5-run-benchmark
3. learn to add your own files to the image, e.g.:
https://github.com/cirosantilli/linux-kernel-module-cheat/tree/657c59249e56d861bb0a437a1b1c757797281910#add-new-files-to-the-buildroot-image
