[gem5-users] Query related to TLB in gem5

Hi all, I have some questions related to TLB implementation in gem5. Gem5 seems to have implemented separate TLB for instruction and data paths, but I see that it has only one level. Real systems seems to have 2 levels of TLB, which I think is missing in gem5. Also, I see that TLB is not set associ

Hi all, I would like to know how page table walking actually works in x86 TimingSImpleCPU, which uses a timing access memory model. Previously, I tried to look at how the page table is walker for AtomicSimpleCPU which uses an atomic access memory model. In function Walker::WalkerState::startWalk(),
