Struct x86_64::registers::control::Cr3
[−]
[src]
pub struct Cr3;
Contains the physical address of the level 4 page table.
Methods
impl Cr3[src]
pub fn read() -> (PhysFrame, Cr3Flags)[src]
Read the current P4 table address from the CR3 register.
pub unsafe fn write(frame: PhysFrame, flags: Cr3Flags)[src]
Write a new P4 table address into the CR3 register.
Safety
Changing the level 4 page table is unsafe, because it's possible to violate memory safety by changing the page mapping.
