Hi, TLB is just a cache of VPN to PFN mappings, thus it does not nothing to do with selecting PFNs.
In the SE mode the mappings are created by gem5 itself here: https://gem5.googlesource.com/public/gem5/+/refs/heads/stable/src/sim/process.cc#317 The easiest would be to set paddr = vaddr, but you might have to consider things like page alignment and memory regions (e.g., what if the paddr you want to use is already used for a code page...?).

How to enforce the TLB in the system emulated (SE) mode to always produce Page Frame Number = Virtual Page Number. I may want to try two things: 1. Don't disable the TLB but have PFN=VPN 2. Disable TLB , so addresses in the workload are physical addresses. Thanks, a lot. _______________________________________________ gem5-users mailing list -- gem5-users@gem5.org To unsubscribe send an email to gem5-users-le...@gem5.org
