Hi, Based on my understanding of what you are trying to do, I would suggest looking into src/arch/x86/tlb.cc (assuming you want to use x86) around line 400, to see how to access page table entries from a process pointer. syscall_emul.hh already includes sim/process.hh, so you can follow what is done in tlb.cc and play with the flags that you want to change.
