Struct PageTableRef

pub struct PageTableRef<'a, P: PTEArch> { /* private fields */ }

A reference to a page table.

LEN is the number of entries in a page table. LEVEL is the max level of the page table.

Implementations

impl<'a, P: PTEArch> PageTableRef<'a, P>

pub fn create_empty(access: &mut impl Access) -> PagingResult<Self>

Creates a new page table reference.

pub fn new_with_level( level: usize, access: &mut impl Access, ) -> PagingResult<Self>

New page table and returns a reference to it.

level is level of this page, should from 1 to up.

pub fn from_addr(addr: usize, level: usize) -> Self

pub fn level(&self) -> usize

pub fn paddr(&self) -> usize

pub unsafe fn map_region( &mut self, config: MapConfig, size: usize, allow_block: bool, access: &mut impl Access, ) -> PagingResult<()>

.

Errors

This function will return an error if .
