Hi,
Prefetching will impact the replacement in a way it can bring non demand
dead blocks which will not be referenced in the application and force evict
a demand block.
You can disable prefetchers by editing src/configs/common/Caches.py and
setting the parameter “prefetcher” to NULL just for L2 cache.
