I would suggest implementing these counters in the tick() function in the src/cpu/o3/cpu.cc file because this method is called every cycle. However, I am not an expert in the cache code from gem5, therefore i don't know how to access information from MSHR. Additionally, I believe you should implement the logic in the src/mem/cache/cache.cc and, in the tick method(), just called this function that implements this logic to get information from MSHR.

The first function needs to return the number of outstanding demand misses in MSHR, it shows the total number of misses in MSHR for each cycle. The second function needs to return the number of hits occur in each cycle, if no hits in that cycle, it will return 0. I need the cycle information, so these functions need to be called every cycle and get statistics. I want to know how to implement these functions in gem5, can I implement the logic in src/mem/cache/cache.cc? Any ideas or suggestions for implementing would be helpful. Thank you very much.
