◆ add_page_1g()
Add Page (1g Granularity)
Adds a page to the page table structure. Note that this is the public function, and should only be used to add pages to the PML4 page table. This function will call a private version that will parse through the different levels making sure the virtual address provided is valid.
- Precondition
- expects: none
- Postcondition
- ensures: none
- Parameters
-
| addr | the virtual address to the page to add |
- Returns
- the resulting pte. Note that this pte is blank, and its properties (like present) should be set by the caller

◆ add_page_2m()
Add Page (2m Granularity)
Adds a page to the page table structure. Note that this is the public function, and should only be used to add pages to the PML4 page table. This function will call a private version that will parse through the different levels making sure the virtual address provided is valid.
- Precondition
- expects: none
- Postcondition

- Parameters
-
| addr | the virtual address to the page to add |
- Returns
- the resulting pte. Note that this pte is blank, and its properties (like present) should be set by the caller

◆ add_page_4k()
Add Page (4k Granularity)
Adds a page to the page table structure. Note that this is the public function, and should only be used to add pages to the PML4 page table. This function will call a private version that will parse through the different levels making sure the virtual address provided is valid.
- Precondition
- expects: none

◆ remove_page()
Remove Page
Removes a page from the page table. Note that this function cleans up as it goes, removing empty page tables if they are detected. For this reason, this operation can be expensive if mapping / unmapping occurs side by side with addresses that are similar (page tables will be needlessly removed)
- Precondition
- expects: none
- Postcondition
- ensures: none
- Parameters
-
| addr | the virtual address of the page to remove |

◆ virt_to_pte()
Virt to Page Table Entry
Returns the PTE associated with the provided virtual address. If no PTE exists for the virtual address provided, an exception is thrown.
- Precondition
- expects: none
- Postcondition
- ensures: none
- Parameters
-
| addr | the virtual address of the pte to locate |

◆ pt_to_mdl()
Page Table to Memory Descriptor List
This function converts the internal page table tree structure into a linear, memory descriptor list. Page table entry information is not provide, only the page tables. pages.
- Precondition
- expects:
- Postcondition
- ensures:
- Returns
- memory descriptor list
