Berti prefetcher design and integration in XS-GEM5

[kislay536]

Hi,
I’ve been going through the XS-GEM5 codebase.
I had a few questions specifically about the Berti prefetcher implementation:

1. Is the Berti prefetcher designed to rely on the XS-GEM5 cache framework (e.g., multi-prefetcher coordination), or is its core logic relatively modular?
2. Is it currently instantiated for a particular cache level (e.g., L1 vs L2), or designed to be reusable across levels?
3. Would it be reasonable to treat this implementation as a reference and reimplement Berti in upstream gem5, rather than trying to directly reuse the code?

Thanks!
