Hi Giacomo,
I have run the command and the gcc.rcS script below but the script doesn't stop
at 1000 instructions. Any help would be appreciated.
The command is:
./build/X86/gem5.fast ./configs/example/fs.py --maxinsts=1000
--kernel=/home/abdkhail/linux_new/vmlinux
--disk-image=/home/abdkhail/ubuntu16.img
--script=configs/boot/benchmark/gcc.rcS --mem-size=3GB --num-cpus=4
--cpu-clock=2GHz --caches --l2_size=2MB --l1i_size=32kB --l1d_size=32kB
--checkpoint-restore=3
The gcc.rcS is:
cd
/home/ubuntu/cpu/benchspec/CPU2006/403.gcc/run/run_base_ref_amd64-m64-gcc42-nn.0000
/sbin/m5 resetstats
./gcc_base.amd64-m64-gcc42-nn 166.i -o 166.s
/sbin/m5 dumpstats
#echo "Done :D"
/sbin/m5 exit
This also what i got on the output screen:

If by chance simulation is stuck while generating a checkpoint, I suggest you
to use GDB to understand where it is stuck.
Let us know your findings.

I don't know what is going on and what the boot script is doing.
For me the easy way to create a checkpoint is to
1) $cd util/term
2) $make
Now you have m5term compiled.
>From another terminal run your simulation (without bootscritpt) and see which
>is the local port (usually 3456)
>From the other terminal do
$./m5term localhost 3456
Now you have a terminal attached to your guest system: once you boot Linux,
just type on this terminal:
$/sbin/m5 checkpoint
This will create a checkpoint.
If you now want to exit simulation, type on the same terminal
$/sbin/m5 exit
Regards
Giacomo

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.

Subject: Re: [gem5-users] Run CPU 2006 benchmark on gem5 fs mode
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.

Subject: Re: [gem5-users] Run CPU 2006 benchmark on gem5 fs mode
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.
