Implementations

impl PageDirectoryPointerTable

pub const fn zeroed() -> Self

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

pub const fn get(&self, i: L3Index) -> PdptEntry

Read an entry at i.

Plain load; does not imply any TLB maintenance.

pub const fn set(&mut self, i: L3Index, e: PdptEntry)

Write an entry at i.

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

pub const fn set_zero(&mut self, i: L3Index)

Set the entry at i to PdptEntry::zero.

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

pub const fn index_of(va: VirtualAddress) -> L3Index

Derive the PDPT index from a virtual address.
