Hi, I implemented my prefetcher design which generates prefetches in the calculatePrefetch() function by pushing the prefetch addresses into: std::vector<AddrPriority> &addresses However, what I found out was that the addresses I pushed were Page crossing (so I added MMU to dcache and l2cache in the configs/common/CacheConfig.py) and then had no physical address. Due to no translations I observed that all such prefetches were ultimately rendered useless as it took a ridiculously long time for the prefetch''s virtual addresses (in prefetch queue) to get translated to physical address. I'm using configs/deprecated/example/se.py and I wanted to add a TLB hierarchy for my gem5 run. However I could not find any document/example on how to do so. If anyone has already set up their TLB, do let me know.

 std::vector<AddrPriority> &addresses

Hi Anshul, My research group has recently released a gem5 modification to support page walk (and use of TLB) in syscall emulation mode. You can find it at the following link: https://github.com/mircomannino/gem5/tree/rapido24 The modifications were made only for RISC-V, I don't know which ISA you are working with. The changes made are explained in an accepted but not yet published paper. I will let you know when the paper is available.
