Problems upgrading to latest version
I had been running version 22, and I had also run the bootcamp 2022 example for demonstrating MESI_Two_Level protocol. After I upgraded to version 23.0.0.1, I first noticed that I had trouble compiling the example. After finding a work around, to generate gem5.opt, The program seems to be missing the parameter processor (which was not needed when I ran version 22. I can use some suggestions on how to run this example with the new version (What has changed?
The example where it worked in version 22, but not in version 23:
scons build/NULL_MESI_Two_Level/gem5.opt --default=NULL PROTOCOL=MESI_Two_Level -j16
The program gave me an error:
scons build/NULL_MESI_Two_Level/gem5.opt --default=NULL PROTOCOL=MESI_Two_Level -j16
scons: Reading SConscript files ...

I think there are a few things going on here causing problems.
-
The pre-commit hooks aren't being installed correctly. i think this is due to some directory permission error. The '/.cache' directory appears to not have the right permissions here. Perhaps this you did something here with sudo? You can recreate this error using "/util/pre-commit-install.sh". Either way it isn't necessary that these hooks are installed. If this step fails gem5 should still work.
-
The "error not "build' dir found on target path": I'm pretty sure you either didn't execute the this in the root of the gem5 directory or you made a typo when typing the scons command. The "-j16" at the end of that command makes me believe there was some kind of error with passing the
-jflag and specifying the build path. -
The "procesor" argument has been renamed to "generator" for the test board. I believe this is easily fixed. All you need to do is change https://github.com/gem5bootcamp/gem5-bootcamp-env/blob/1afde18b5c4240736507a68fd2e54351be31f30d/materials/using-gem5/04-cache-models/simple_cache_run.py#L98 to
generator=generator,.
It should be noted that the 2022 gem5 was build with v22.0 of gem5. If you're following the Bootcamp we strongly advise using v22.0 of gem5. There have been numerous codebase updates over the past year and we can't guarantee all of the tutorials will work as intended with the latest version.

Bobby,
You suggestion (number 3) worked, and I was able to run the compiled gem5.opt by fixing generator=generator. I did have an additional error which I corrected by:
motherboard._pre_instantiate()
m5.instantiate()
I am including the two runs (with error and no error). I have a couple of concerns. I used the docker commands in gem5-bootcamp-env to build a docker container that I used to run gem5. This seems to run in both WSL, and on my stand alone Ubuntu linux system. When I run via the docker I am root, so there may be some issues with root privilege.
I don’t have a problem running version 22 in my class, but I am concerned that I don’t control that repository. I need to make sure that repository will remain stable while I teach with that version. If I have enough time to prepared, I will also see if I can get it running on the jetson orin nano system since we are providing them to our students.
I think I disagree with statement 2. The build was following the example from Marjan Fariborz Cache Systems charts. I was in the gem5 directory (under the gem5-bootcamp-env directory). The argument –j16 indicates use all 16 cores. I am not sure why the statement:
scons build/NULL_MESI_Two_Level/gem5.opt --default=NULL PROTOCOL=MESI_Two_Level –j16
Produces the error message:
Error: No non-leaf 'build' dir found on target path. /home/besernd1/gem5-bootcamp-env/gem5/–j16
If I use:
python3 which scons build/NULL_MESI_Two_Level/gem5.opt --default=NULL PROTOCOL=MESI_Two_Level -j16
Everything works correctly.
Thank-you for your help,
Nick

I think there are a few things going on here causing problems.
-
The pre-commit hooks aren't being installed correctly. i think this is due to some directory permission error. The '/.cache' directory appears to not have the right permissions here. Perhaps this you did something here with sudo? You can recreate this error using "/util/pre-commit-install.sh". Either way it isn't necessary that these hooks are installed. If this step fails gem5 should still work.
-
The "error not "build' dir found on target path": I'm pretty sure you either didn't execute the this in the root of the gem5 directory or you made a typo when typing the scons command. The "-j16" at the end of that command makes me believe there was some kind of error with passing the
-jflag and specifying the build path. -
The "procesor" argument has been renamed to "generator" for the test board. I believe this is easily fixed. All you need to do is change https://github.com/gem5bootcamp/gem5-bootcamp-env/blob/1afde18b5c4240736507a68fd2e54351be31f30d/materials/using-gem5/04-cache-models/simple_cache_run.py#L98 to
generator=generator,.
It should be noted that the 2022 gem5 was build with v22.0 of gem5. If you're following the Bootcamp we strongly advise using v22.0 of gem5. There have been numerous codebase updates over the past year and we can't guarantee all of the tutorials will work as intended with the latest version.

I had been running version 22, and I had also run the bootcamp 2022 example for demonstrating MESI_Two_Level protocol. After I upgraded to version 23.0.0.1, I first noticed that I had trouble compiling the example. After finding a work around, to generate gem5.opt, The program seems to be missing the parameter processor (which was not needed when I ran version 22. I can use some suggestions on how to run this example with the new version (What has changed?
The example where it worked in version 22, but not in version 23:
scons build/NULL_MESI_Two_Level/gem5.opt --default=NULL PROTOCOL=MESI_Two_Level –j16
The program gave me an error:

You're missing the pre-commit/commit-msg hooks. These hook help to ensure your
code follows gem5's style rules on git commit and your commit messages follow
our commit message requirements. This script will now install these hooks in
your .git/hooks/ directory.

It is strongly recommended you install the pre-commit hooks before working with gem5. Do you want to continue compilation (y/n)?
y
Error: No non-leaf 'build' dir found on target path. /home/nbeser1/gem5-bootcamp-env/gem5/–j16
However if I run the following:
python3 which scons build/NULL_MESI_Two_Level/gem5.opt --default=NULL PROTOCOL=MESI_Two_Level -j16
The program generates gem5.opt
Unfortunately, I also get the following error when I try to run gem5.opt:
