Implementations

impl MemorySet

pub fn new_bare() -> Self

pub fn token(&self) -> usize

pub fn insert_framed_area( &mut self, start_va: VirtAddr, end_va: VirtAddr, permission: MapPermission, )

Assume that no conflicts.

pub fn remove_area_with_start_vpn(&mut self, start_vpn: VirtPageNum)

fn push(&mut self, map_area: MapArea, data: Option<&[u8]>)

fn map_trampoline(&mut self)

Mention that trampoline is not collected by areas.

pub fn new_kernel() -> Self

Without kernel stacks.

pub fn from_elf(elf_data: &[u8]) -> (Self, usize, usize)

Include sections in elf and trampoline, also returns user_sp_base and entry point.

pub fn from_existed_user(user_space: &MemorySet) -> MemorySet

pub fn activate(&self)

pub fn translate(&self, vpn: VirtPageNum) -> Option<PageTableEntry>

pub fn recycle_data_pages(&mut self)
