[−][src]Struct x86_64::registers::control::Cr3

pub struct Cr3;

Contains the physical address of the level 4 page table.

Implementations

impl Cr3[src]

pub fn read() -> (PhysFrame, Cr3Flags)[src]

Read the current P4 table address from the CR3 register.

pub fn read_raw() -> (PhysFrame, u16)[src]

Read the current P4 table address from the CR3 register

pub fn read_pcid() -> (PhysFrame, Pcid)[src]

Read the current P4 table address from the CR3 register along with PCID. The correct functioning of this requires CR4.PCIDE = 1. See Cr4Flags::PCID

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.

pub unsafe fn write_pcid(frame: PhysFrame, pcid: Pcid)[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. Cr4Flags::PCID must be set before calling this method.
