Hi, I have problems changing the replacement policy to be used by the
simulator. I just want to change the LLC policy.
I saw the options for se.py: "./build/X86/gem5.opt configs/example/se.py
-h" but there is not an option for the replacement policy, there are
options for the cache size and assoc. Also the files CacheConfig.py and
Caches.py used by se.py have not defined the replacement policy to be used.
I have tried looking for "repl" and "replacement" using grep through the
entire gem_stable tree, after analyzing the results I found many examples
where repl is set to NULL.
I just want to know how to change the replacement policy from LRU to
fa_lru, both of them defined in src/mem/cache/tags/. I really appreciate
your help.
Best Regards
Roberto
