Efer

x86_64::registers::model_specific

Struct Efer 

Source 
pub struct Efer;
Expand description

The Extended Feature Enable Register.

Implementations§

Source§

impl Efer

Source

pub fn read() -> EferFlags

Read the current EFER flags.

Source

pub fn read_raw() -> u64

Read the current raw EFER flags.

Source

pub unsafe fn write(flags: EferFlags)

Write the EFER flags, preserving reserved values.

Preserves the value of reserved fields.

§Safety

Unsafe because it’s possible to break memory safety with wrong flags, e.g. by disabling long mode.

Source

pub unsafe fn write_raw(flags: u64)

Write the EFER flags.

Does not preserve any bits, including reserved fields.

§Safety

Unsafe because it’s possible to break memory safety with wrong flags, e.g. by disabling long mode.

Source

pub unsafe fn update<F>(f: F)
where F: FnOnce(&mut EferFlags),

Update EFER flags.

Preserves the value of reserved fields.

§Safety

Unsafe because it’s possible to break memory safety with wrong flags, e.g. by disabling long mode.

Source§

impl Efer

Source

pub const MSR: Msr

The underlying model specific register.
