Implementations

impl PageDirectory

pub const fn zeroed() -> Self

Create a fully zeroed Page Directory (all entries non-present).

pub const fn get(&self, i: L2Index) -> PdEntry

Read the entry at i.

Plain load; does not imply any TLB synchronization.

pub const fn set(&mut self, i: L2Index, e: PdEntry)

Write the entry at i.

Caller must handle any required TLB invalidation when changing active mappings.

pub const fn set_zero(&mut self, i: L2Index)

Set the entry at i to PdEntry::zero.

Caller is responsible for necessary TLB invalidations if this affects an active address space.

pub const fn index_of(va: VirtualAddress) -> L2Index

Derive the PD index from a virtual address.
