Struct ControlRegister8

pub struct ControlRegister8(/* private fields */);

Available on x86-64 only.

CR8: System control register for controlling interrupts based on priority.

Getters and setters for this structure only access a value in memory, not the register itself. Use the get and set methods to work with the actual register.

Implementations

impl ControlRegister8

pub fn task_priority_level(&self) -> u8

CR8.TPL: Threshold for blocking low-priority interrupts. Lower values are higher priority.

pub fn set_task_priority_level(&mut self, value: u8)

CR8.TPL: Threshold for blocking low-priority interrupts. Lower values are higher priority.

pub fn with_task_priority_level(&self, value: u8) -> Self

CR8.TPL: Threshold for blocking low-priority interrupts. Lower values are higher priority.

impl ControlRegister8

pub fn get() -> Self

Retrieve the current value of this register

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.

Trait Implementations

impl Bitfield<usize> for ControlRegister8

fn new(value: T) -> Self

Construct a new bitfield type from its underlying representation

fn value(self) -> T

Unwrap the bitfield into its underlying representation

impl Clone for ControlRegister8

fn clone(&self) -> ControlRegister8

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for ControlRegister8

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for ControlRegister8

fn default() -> ControlRegister8

Returns the “default value” for a type.

impl From<ControlRegister8> for usize

fn from(val: ControlRegister8) -> Self

Converts to this type from the input type.

impl From<usize> for ControlRegister8

fn from(val: usize) -> Self

Converts to this type from the input type.

impl PartialEq for ControlRegister8

fn eq(&self, other: &ControlRegister8) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
