Hello, I am working on implementing a specific cache replacement policy. This policy basically relies on building/collecting the history of both memory references (load/store addresses). Also, it operates using the associating hashed PC of the load/store instructions themselves. So, code-wise, it requires direct access to these factors.
Now, in gem5, the cache replacement policies (by default) inherit ReplaceableEntry class, which has the set and the way information for the new replacement. However, assuming my case where I have a block in the design that expects the stream of the aforementioned data (i.e., memory address and PC), I could not find a way through which my replacement policy may have access to this information. How can I solve this? Thanks! -- *Best,Abdelrahman Hussein*
