Struct mycelium_kernel::arch::interrupt::apic::LocalApic

pub struct LocalApic {
    msr: Msr<u64>,
    base: VAddr,
}

Fields

msr: Msr<u64>

base: VAddr

Implementations

impl LocalApic

pub fn try_new() -> Result<LocalApic, FeatureNotSupported>

Try to construct a LocalApic.

Returns

• Ok(LocalApic) if this CPU supports the APIC interrupt model.
• Err(FeatureNotSupported) if this CPU does not support APIC interrupt handling.

pub fn new() -> LocalApic

pub fn enable(&self, spurious_vector: u8)

pub fn start_periodic_timer(
    &self,
    interval: Duration,
    vector: u8
) -> Result<(), InvalidDuration>

pub unsafe fn end_interrupt(&self)

Sends an End of Interrupt (EOI) to the local APIC.

This should be called by an interrupt handler after handling a local APIC interrupt.

Safety

This should only be called when an interrupt has been triggered by this local APIC.

Trait Implementations

impl Debug for LocalApic

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

Formats the value using the given formatter.

impl Default for LocalApic

fn default() -> LocalApic

Returns the “default value” for a type.
