Struct Vmar 

Source 
pub struct Vmar { /* private fields */ }
Expand description

Virtual Memory Address Region (VMAR)

Manages a region of virtual address space, similar to Asterinas VMAR. Used for process address space management.

Implementations§

Source§

impl Vmar

Source

pub fn new(base: VirtAddr, size: usize) -> Self

Creates a new VMAR

Source

pub fn base(&self) -> VirtAddr

Returns the base virtual address

Source

pub fn size(&self) -> usize

Returns the size of the region

Source

pub fn alloc( &self, offset: usize, size: usize, flags: MapFlags, ) -> Result<VirtAddr, MapError>

Allocates a new region within this VMAR

Source

pub fn dealloc(&self, offset: usize) -> Result<(), MapError>

Deallocates a region within this VMAR
