pub struct Efer;
Expand description

The Extended Feature Enable Register.

Implementations§

source§

impl Efer

source

pub fn read() -> EferFlags

Available on crate feature instructions only.

Read the current EFER flags.

source

pub fn read_raw() -> u64

Available on crate feature instructions only.

Read the current raw EFER flags.

source

pub unsafe fn write(flags: EferFlags)

Available on crate feature instructions only.

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)

Available on crate feature instructions only.

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),

Available on crate feature instructions only.

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.
