Paging

The Paging window provides a view to the tables that are used on the system for Paging. Use it to create or modify tables and to analyze the tables which are set up by the software running on the target.

This includes the paging modes 32-bit, PAE and IA-32e. Depending on the paging mode, the window displays one of four different types of tables: page table (PT), page directory (PD), page-directory-pointer table (PDPT), and page map level 4 (PML4). The top-most table is shown when the Paging window opens.

If a table entry points to a sub-table, you can expand the table entry to this underlying table by clicking on the expansion item.

The Paging window only displays page entries if they point to a present page or present table. It hides entries whose present bit is not set . To display all entries, deselect Only Show Present in the pop-up menu.

Columns

Index
Shows the table type and index of the table entry. PT refers to page table, PD to page directory, PML4 to page map level 4, and PDPT to page-directory-pointer table. The first index is 0; the amount of entries is depending on the table size.
Virtual Memory Range

Each table entry contains an address that points to the next table or the physical location of the page. Double-click the column to change the base address.
