why pf_page_addr is not equal to page_addr?

[qiao-huan]

I am porting Berti to the latest version of ChampSim. After I modified the interfaces of all functions in Berti to be consistent with the latest version of ChampSim, it compiled successfully. However, I encountered the following problem: uint32_t CACHE::pref_prefetcherDberti_concurso_prefetcher_cache_operate(uint64_t, uint64_t, uint8_t, bool, uint8_t, uint32_t): Assertionpf_page_addr == page_addr' failed.`

But why？I did not change any functional code in Berti.

Hello, I have a pull request of Berti for the latest version of ChampSim (https://github.com/ChampSim/ChampSim/pull/486).

Berti concurso is not the MICRO22 Berti (vberti).
