Struct keos::mm::ContigPages

source · 
pub struct ContigPages { /* private fields */ }
Expand description

A contiguous pages representation.

Implementations§

source§

impl ContigPages

source

pub fn new(size: usize) -> Option<Self>

Allocate a page.

source

pub fn new_with_align(size: usize, align: usize) -> Option<Self>

Allocate a page with align

source

pub fn va(&self) -> Va

Get virtual address of this page.

source

pub fn pa(&self) -> Pa

Get physical address of this page.

source

pub fn split(self) -> Vec<Page>

Split the ContigPages into multiple pages.

source

pub unsafe fn from_va(va: Va, size: usize) -> Self

Constructs a page from a va.

Safety

This function is unsafe because improper use may lead to memory problems. For example, a double-free may occur if the function is called twice on the same raw pointer.
