PTE and PDE

PVDF: page Directory Entry

PTE: page table entry (recording the real physical address of the virtual address)

Example with kerneldebug:

 

Kd>! PTE 80572000
Va 80572000
Pdat c0300804 PTE at c02015c8
Contains 0003d163 contains 00572121
PFN 3D-G-DA--KWEV PFN 572-G--A--KREV

 

Check the PDE and PTE of 80572000. We can see that the virtual address 80572000 corresponds to the PTE of c02015c8, which records the actual physical memory, 00572121 (of course, the last 12bit should be cleared)

Read the virtual address 80572000, equivalent to read the physical address 00572000.
