IA32_EFER: Model-specific register that controls features relating to 64-bit operation.

Implementations§

source§

impl ExtendedFeatureEnableRegister

source

pub fn syscall(&self) -> bool

IA32_EFER.SCE: Support SYSCALL/SYSRET in 64-bit mode.

source

pub fn long_mode_enabled(&self) -> bool

IA32_EFER.LME: Support 64-bit mode.

source

pub fn long_mode_active(&self) -> bool

IA32_EFER.LMA: Indicates 64-bit mode is active. Read-only.

This is logically the equivalent to [Self::long_mode_enabled] & [ControlRegister0::paging].

source

pub fn no_execute(&self) -> bool

IA32-EFER.NXE: Support no-execute (NX) bit in page tables.

source

pub fn set_syscall(&mut self, value: bool)

IA32_EFER.SCE: Support SYSCALL/SYSRET in 64-bit mode.

source

pub fn with_syscall(&mut self, value: bool) -> Self

IA32_EFER.SCE: Support SYSCALL/SYSRET in 64-bit mode.

source

pub fn set_long_mode_enabled(&mut self, value: bool)

IA32_EFER.LME: Support 64-bit mode.

source

pub fn with_long_mode_enabled(&mut self, value: bool) -> Self

IA32_EFER.LME: Support 64-bit mode.

source

pub fn set_long_mode_active(&mut self, value: bool)

IA32_EFER.LMA: Indicates 64-bit mode is active. Read-only.

This is logically the equivalent to [Self::long_mode_enabled] & [ControlRegister0::paging].

source

pub fn with_long_mode_active(&mut self, value: bool) -> Self

IA32_EFER.LMA: Indicates 64-bit mode is active. Read-only.

This is logically the equivalent to [Self::long_mode_enabled] & [ControlRegister0::paging].

source

pub fn set_no_execute(&mut self, value: bool)

IA32-EFER.NXE: Support no-execute (NX) bit in page tables.

source

pub fn with_no_execute(&mut self, value: bool) -> Self

IA32-EFER.NXE: Support no-execute (NX) bit in page tables.

source§

impl ExtendedFeatureEnableRegister

source

pub fn get() -> Self

Retrieve the current value of this register

source

pub unsafe fn set(value: Self)

Update the register to the given value.

§Safety

Altering certain system flags can have dramatic effects on the execution of this and other programs, including memory safety.
