Hello, To my understanding, number_cache_levels reflects what you said in number 1. In number 2, I personally only tried number_of_L2s=1.
When you mention that no power difference was observed with and without L2 cache, did you see the L2 cache in the McPAT output file? If you don't have detailed power info, try the -print_level flag.
