Struct PageTableRoot 

#[repr(align(4096))]
pub struct PageTableRoot([Pml4e; 512]);

A page table root.

It wraps the Pml4e array to ensure page table align to 4096. Note that it is not allowed to modified the larger indices than Self::KBASE, which are reserved for kernel address.

Tuple Fields

0: [Pml4e; 512]

Implementations

impl PageTableRoot

pub const KBASE: usize = 256usize

pub fn new_boxed() -> Box<Self>

Create a empty PageTableRoot.

pub fn new_boxed_with_kernel_addr() -> Box<Self>

Create a new PageTableRoot that allowed to access the kernel addresses.
