[Qemu-ppc] How to catch and check all address access requests in qemu? |

Using Qemu to run a guest system, the guest virtual address will be translated to guest physical address by MMU, then be translated to host virtual address by Qemu.
In my case, I need to add a checker between virtual PowerPC CPU and memory/MMIO. This checker will catch all address access request, check if the address follows some rules. If address violates rules, the access request will be discarded.
My question is: where is the proper location to put my checker code? I reviewed code in file Memory.c, but functions in file are about memory add/remove. Could you give any suggesions?
Thanks,
Kaiyuan Liang
