A Intel 64-bit x86 CPU,four-level hierarchical page table.Each for levels of page table can contain 512 entries, and the page size is 4KB. What's the maximum size for virtual memory and physical memory?
I think the maximum virtual memory should be 2^48 in that 9 bits for referencing the position of page table and there are 4 page tables. Thus 4*9+12=48(4KB offset). But I am not sure how to calculate the maximum physical memory. Or it just cannot tell from this information?
