Struct PageTable 

#[repr(C, align(4096))]
pub struct PageTable {
    entries: [PtEntry4k; 512],
}

The Page Table (L1): 512 entries, 4 KiB-aligned.

Fields

entries: [PtEntry4k; 512]

Implementations

impl PageTable

pub const fn zeroed() -> Self

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

pub const fn get(&self, i: L1Index) -> PtEntry4k

Read the entry at i.

Plain load; does not imply any TLB synchronization.

pub const fn set(&mut self, i: L1Index, e: PtEntry4k)

Write the entry at i.

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

pub const fn set_zero(&mut self, i: L1Index)

Set the entry at i to PtEntry4k::zero.

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

pub const fn index_of(va: VirtualAddress) -> L1Index

Derive the PT index from a virtual address.
