Implementations§

source§

impl PageTable

source

pub fn new() -> Self

Create a empty page table.

source

pub fn pa(&self) -> Pa

Get physical address of this page table.

source

pub fn map( &mut self, va: Va, pg: Page, perm: Permission ) -> Result<(), PageTableMappingError>

Map pg into va with permission perm.

source

pub unsafe fn do_map( &mut self, va: Va, pa: Pa, perm: Permission ) -> Result<(), PageTableMappingError>

Map pa into va with permission perm.

Safety

pa must be valid.

source

pub fn unmap(&mut self, va: Va) -> Result<Page, PageTableMappingError>

Unmap the va and returns Page that was mapped to va.

source

pub fn walk(&self, va: Va) -> Result<&Pte, PageTableMappingError>

Walk the page table and return corresponding pte of the va if exist.
