Hi Matt, I am currently trying to add the stats by myself. I also noticed that neither hit nor miss stats are updated for L3 Cache.
But, I am facing a different issue now. The directory ctrl (DirCntrl) in GPU_VIPER.py has a L3 cache (L3Cache). But, there is also a separate L3Cntrl class which inherits from L3Cache_Controller, but it is unused. The L3Cache_Controller is generated from MOESI_AMD_Base-L3cache.sm, which is a part of the Viper protocol. If the L3Cache_Controller isn't used, then why is it a part of the Viper protocol ? Does the L3 Cache not maintain any coherency ? Is this the intended behaviour of the default configuration ?
