Hi, I am using classic memory-model in GEM5. I observed that an UpgradeReq command invalidates the line in cache. This behavior is acceptable for peer-caches in the same-level. However, i am not sure if the UpgradeReq should invalidate the cache line in the lower level caches (Caches closer to the main-memory are lower levels, in my terminology). Can someone through light on this?
