Hello everyone, I have the same question. What does response latency in gem5 mean? And the hit latency is the read latency or the write latency? Thanks.

The total latency is 2 or (2 + 2) ? Same question if the data is in the L2 (and not the L1), the total latency is 20, (2 + 20), (20 + 20) or (2 + 20 + 20 + 2) ? Does the latency affect read misses or both read and write misses? Thanks for the clarifications.
