Struct aarch64_paging::linearmap::LinearTranslation

pub struct LinearTranslation { /* private fields */ }

Linear mapping, where every virtual address is either unmapped or mapped to an IPA with a fixed offset.

Implementations

impl LinearTranslation

pub fn new(offset: isize) -> Self

Constructs a new linear translation, which will map a virtual address va to the (intermediate) physical address va + offset.

The offset must be a multiple of PAGE_SIZE; if not this will panic.

Trait Implementations

impl Clone for LinearTranslation

fn clone(&self) -> LinearTranslation

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for LinearTranslation

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl PartialEq for LinearTranslation

fn eq(&self, other: &LinearTranslation) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl Translation for LinearTranslation

fn allocate_table(&self) -> (NonNull<PageTable>, PhysicalAddress)

Allocates a zeroed page, which is already mapped, to be used for a new subtable of some pagetable. Returns both a pointer to the page and its physical address.

unsafe fn deallocate_table(&self, page_table: NonNull<PageTable>)

Deallocates the page which was previous allocated by allocate_table.

fn physical_to_virtual(&self, pa: PhysicalAddress) -> NonNull<PageTable>

Given the physical address of a subtable, returns the virtual address at which it is mapped.
