Hi, I'm playing with a 5GB Windows 7 SP0 64bit memory dump and I have some problems with processes mapped over 4GB. Pslist only shows System process. Maybe it's because System is the only process mapped under 4GB?

For a physical page size of 4KB, vtop() in amd64.py convert the address:   1- get pml4e   2- get pdpte   3- get pde   4- get pte   5- return get_phys_addr The function get_phys_addr() in step #5 is in intel.py and is 32bit only:    def get_phys_addr(self, vaddr, pte_value):        return (pte_value & 0xfffff000) | (vaddr & 0xfff) If the pte_value is 64bit, it get cuts in the get_phys_addr()?
