Dear All,
According to the documentation, there are existed two-level MOESI protocol and
three-level MESI protocol in Gem5 repository. However both of them are either
only two-level or single clusivity.
Now I need to configure a private-L1, strictly inclusive private-L2 and
strictly exclusive shared-L3 cache hierarchy in Ruby. I want to edit the
existed MOESI/MESI protocol but
I cannot understand which code lines are dedicated for clusivity in these
existed Ruby-based implementation? For CHI, there are parameter for clusivity
but for MOESI/MESI, documents didn't tell.
What if I want to add a datapath which directly connect LSQ to L3 cache, what
should I do? I think I add to add a sequencer between CPU and L3 cache
controller. And can anyone give any ideas?
Thanks sincerely in advance.
