Re: [Gems-users] Inclusive L2 cache

[Derek Hower <drh5@xxxxxxxxxxx>]

Inclusivity/exclusivity is a coherence-level issue.  Thus, it is determined solely by the behavior of the SLICC generated protocol.  To the best of my knowledge, all released protocols in GEMS are inclusive.

Hi all,

I am trying to add another cache besides L1/L2 to my target system like a victim cache or an RAC. So, I am wondering how to determine exclusivity of the caches in GEMS? For example, MOESI_SMP_directory protocol has a single SLICC controller for L1/L2, does this mean that the L2 is inclusive? Where in the GEMS code is this determied?

Thanks for any help.

Regards,

Ed
