I tried to follow the charts that were published (06 Modeling Cache Coherence) and I copied the completed code into gem5/src/mem/ruby/protocol. After successfully building the gem5.opt for ALL_MyMSI, I tried to run the script on the ARM Jetson:
$ build/ALL_MyMSI/gem5.opt configs/learning_gem5/part3/simple_ruby.py gem5 Simulator System. https://www.gem5.org gem5 is copyrighted software; use the --copyright option for details. gem5 version 24.0.0.0 gem5 compiled Sep 21 2024 17:41:24 gem5 started Sep 21 2024 17:54:06 gem5 executing on Gem5ubuntu22, pid 72524 command line: build/ALL_MyMSI/gem5.opt configs/learning_gem5/part3/simple_ruby.py fatal: This system assumes MSI from learning gem5! I noticed that there was no youtube video for this charts, so I am not sure how to debug this problem. I am also getting other errors on the X86 Checking whether __i386__ is declared... no Checking whether __x86_64__ is declared... yes ValueError: Could not find MY_MSI.slicc in PROTOCOL_DIRS: File "/home/nbeser1/2024/gem5/SConstruct", line 966: SConscript('src/SConscript', variant_dir=variant_path, exports=exports, File "/usr/lib/python3/dist-packages/SCons/Script/SConscript.py", line 662: return method(*args, **kw) File "/usr/lib/python3/dist-packages/SCons/Script/SConscript.py", line 598: return _SConscript(self.fs, *files, **subst_kw) File "/usr/lib/python3/dist-packages/SCons/Script/SConscript.py", line 285: exec(compile(scriptdata, scriptname, 'exec'), call_stack[-1].globals) File "/home/nbeser1/2024/gem5/src/SConscript", line 564: SConscript(os.path.join(root, 'SConscript'), variant_dir=build_dir, File "/usr/lib/python3/dist-packages/SCons/Script/SConscript.py", line 662: return method(*args, **kw) File "/usr/lib/python3/dist-packages/SCons/Script/SConscript.py", line 598: return _SConscript(self.fs, *files, **subst_kw) File "/usr/lib/python3/dist-packages/SCons/Script/SConscript.py", line 285: exec(compile(scriptdata, scriptname, 'exec'), call_stack[-1].globals) File "/home/nbeser1/2024/gem5/src/mem/ruby/protocol/SConscript", line 99: raise ValueError("Could not find {}.slicc in PROTOCOL_DIRS".format( I could use a hint about these two errors.
