Struct APICBaseRegister

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

Available on x86 or x86-64 only.

IA32_APIC_BASE: A model-specific register that allows relocating an advanced programmable interrupt controller (APIC)’s control structure.

See Intel ISA volume 2 §10.4.3–10.4.4.

Implementations

impl APICBaseRegister

pub fn enabled(&self) -> bool

Can be cleared to disable the APIC. However, it cannot be re-enabled once disabled with this mechanism.

pub fn x2_interface(&self) -> bool

Enable the APIC’s

pub fn bootstrap_processor(&self) -> bool

Indicates that this core was designated as the bootstrap processor for single-threaded operation on startup.

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

Can be cleared to disable the APIC. However, it cannot be re-enabled once disabled with this mechanism.

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

Can be cleared to disable the APIC. However, it cannot be re-enabled once disabled with this mechanism.

pub fn set_x2_interface(&mut self, value: bool)

Enable the APIC’s

pub fn with_x2_interface(&mut self, value: bool) -> Self

Enable the APIC’s

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

Indicates that this core was designated as the bootstrap processor for single-threaded operation on startup.

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

Indicates that this core was designated as the bootstrap processor for single-threaded operation on startup.

impl APICBaseRegister

pub const DEFAULT_ADDRESS: usize = 4_276_092_928usize

The default APIC base address when the processor is reset.

pub fn address(self) -> usize

Base address of the APIC’s registers.

pub fn set_address(&mut self, address: usize)

Update the base address of the APIC’s registers.

impl APICBaseRegister

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<u64> for APICBaseRegister

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 APICBaseRegister

fn clone(&self) -> APICBaseRegister

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for APICBaseRegister

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

Formats the value using the given formatter.

impl Default for APICBaseRegister

fn default() -> APICBaseRegister

Returns the “default value” for a type.

impl From<APICBaseRegister> for u64

fn from(val: APICBaseRegister) -> Self

Converts to this type from the input type.

impl From<u64> for APICBaseRegister

fn from(val: u64) -> Self

Converts to this type from the input type.

impl PartialEq for APICBaseRegister

fn eq(&self, other: &APICBaseRegister) -> 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.
