Hi. I'm Yohan Ko in S. Korea. My question is related with cache memory. I want to make trace file about cache memory to estimate cache vulnerability.
Therefore, this is my question. 1) What is the cache policy in GEM5? I think that general way of cache is write-back. However, I don't know that GEM5 provides what kind of write policy such as write-through and write-back. 2) What is the exact time of incoming? I think the memory data is stored when cache miss is occurred. However, I don't know the exact tick of cache incoming instead of miss time. 3) What does handle the cache eviction? Of course, in write-through policy, cache eviction isn't meaningful. However, in write-back policy, cache eviction is meaningful. I don't know how to handle cache eviction in GEM5 simulator. I want to know eviction time, and eviction policy in GEM5. OK. That's all. I'll wait kind response.
