Hi Nilay, Thanks for the response. Actually this is also the problem I am facing with. The file src/mem/ruby/CacheMemory.cc defines basic class of Ruby Cache. The L1, L2 cache are all defined with slicc file, and only after built can these files be compiled into c++ file. Also I cannot find somewhere else using l2_request_latency or l2_hitLatency, although I know it must be used somewhere. I build gem5 with ALPHA MESI_CMP_directory, 2 level cache, Ruby memory and GARNET network.
Could you please point out where else could this l2_request_latency or l2_hitLatency may possibly be used?
