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