Hello,

Open the file 'MESI_Three_Level.slicc' and you will see the files the protocol MESI_Three_Level is being generated from.

You will see that it is using some components from the MESI_Two_Level protocol.

Hope this is helping you.

Hello

1.I am able to successfully generate the executable gem5 simulator for [ARM ISA, MESI_Three_Level protocol]. The command I used being:

a.scons -j4 build/ARM_MESI_3_level/gem5.opt --default=ARM PROTOCOL=MESI_Three_Level SLICC_HTML=True

2.Also, I am able successfully generate the executable gem5 simulator for [X86 ISA, MESI_Three_Level protocol]. The command I used being:

a.scons -j4 build/X86_MESI_3_level/gem5.opt --default=X86 PROTOCOL=MESI_Three_Level SLICC_HTML=True

However, if I look in src/mem/ruby/protocol, the code for MESI_Three_Level is as follows:

[j00533938@lhrplinux00001 protocol]$ ll MESI_Three_Level*

-rw-rw-r-- 1 j00533938 j00533938 40031 May 28 09:17 MESI_Three_Level-L0cache.sm

-rw-rw-r-- 1 j00533938 j00533938 36841 May 28 09:17 MESI_Three_Level-L1cache.sm

-rw-rw-r-- 1 j00533938 j00533938  4270 May 28 09:17 MESI_Three_Level-msg.sm

-rw-rw-r-- 1 j00533938 j00533938   316 Mar 20 17:42 MESI_Three_Level.slicc

Therefore, it looks to me that the code for MESI_Three_Level is not complete. Thus it is not clear to me how the executable gem5 simulator for MESI_Three_Level is being generated.

Any thoughts on this please?

Thanks in advance.
