Struct x86_64::registers::model_specific::Efer [−][src]
pub struct Efer;
The Extended Feature Enable Register.
Methods
impl Efer[src]
impl Eferpub const MSR: Msr
MSR: Msr = Msr(3221225600)
The underlying model specific register.
pub fn read() -> EferFlags[src]
pub fn read() -> EferFlagsRead the current EFER flags.
pub fn read_raw() -> u64[src]
pub fn read_raw() -> u64Read the current raw EFER flags.
pub unsafe fn write(flags: EferFlags)[src]
pub unsafe fn write(flags: EferFlags)Write the EFER flags, preserving reserved values.
Preserves the value of reserved fields. Unsafe because it's possible to break memory safety, e.g. by disabling long mode.
pub unsafe fn write_raw(flags: u64)[src]
pub unsafe fn write_raw(flags: u64)Write the EFER flags.
Does not preserve any bits, including reserved fields. Unsafe because it's possible to break memory safety, e.g. by disabling long mode.
pub unsafe fn update<F>(f: F) where
F: FnOnce(&mut EferFlags), [src]
pub unsafe fn update<F>(f: F) where
F: FnOnce(&mut EferFlags), Update EFER flags.
Preserves the value of reserved fields. Unsafe because it's possible to break memory safety, e.g. by disabling long mode.
