Hi Jiayi, Thanks so much for the information on Abstract Controller's Constructor. I removed the if condition for m_version and now I am getting the stats I wanted. I will let the Profiler.cc remain as it was.
Thanks a lot!

The version is the ID of the controller in its machine type, specified in the protocol configuration file (e.g. configs/ruby/MESI_Three_Level.py). If you want to have the stat for all the controllers, an easy way is to register the stats in the regStats() if you are using the Stats data structure provided in gem5 (not the ones inside mem/ruby/common). If you are using others and need to process the stats before dumping, you can create another function for callback, for example, localCollateStats(), and register it as a dump callback in the constructor.

In the collateStats() function in StateMachine.py , I added the code to calculate the new statistic at the end of the simulation. However, only L1CacheController-0, L2CacheController and Directory-0 shows the value of the new statistic, rest are 0. I suspect this is because the collateStats() function is called only for Node-0. However, I need to calculate the statistic at the end of the simulation for every node. I would like to know the place from where collateStats() is called so that I can call it for every node. Alternatively, is there another function that is called always for all nodes at the end of simulation? Thank you, Vedika. _______________________________________________ gem5-users mailing list -- gem5-users@gem5.org<mailto:gem5-users@gem5.org> To unsubscribe send an email to gem5-users-le...@gem5.org<mailto:gem5-users-le...@gem5.org> %(web_page_url)slistinfo%(cgiext)s/%(_internal_name)s
