Struct x86_64::registers::control::Cr0 [−][src]
pub struct Cr0;
Various control flags modifying the basic operation of the CPU.
Methods
impl Cr0[src]
impl Cr0pub fn read() -> Cr0Flags[src]
pub fn read() -> Cr0FlagsRead the current set of CR0 flags.
pub fn read_raw() -> u64[src]
pub fn read_raw() -> u64Read the current raw CR0 value.
pub unsafe fn write(flags: Cr0Flags)[src]
pub unsafe fn write(flags: Cr0Flags)Write CR0 flags.
Preserves the value of reserved fields. Unsafe because it's possible to violate memory safety by e.g. disabling paging.
pub unsafe fn write_raw(value: u64)[src]
pub unsafe fn write_raw(value: u64)Write raw CR0 flags.
Does not preserve any values, including reserved fields. Unsafe because it's possible to violate memory safety by e.g. disabling paging.
pub unsafe fn update<F>(f: F) where
F: FnOnce(&mut Cr0Flags), [src]
pub unsafe fn update<F>(f: F) where
F: FnOnce(&mut Cr0Flags), Updates CR0 flags.
Preserves the value of reserved fields. Unsafe because it's possible to violate memory safety by e.g. disabling paging.
