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

pub struct LocalApic { /* private fields */ }

Implementations

impl LocalApic

pub fn try_new<A>( pagectrl: &mut impl Map<Size4Kb, A>, frame_alloc: &A ) -> Result<LocalApic, FeatureNotSupported>

where A: Alloc<Size4Kb>,

Try to construct a LocalApic.

Arguments

• pagectrl: a page mapper used to ensure that the local APIC’s memory-mapped register page is mapped and writable.
• frame_alloc: a frame allocator used to allocate page frame(s) while mapping the MMIO register page.

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<A>(pagectrl: &mut impl Map<Size4Kb, A>, frame_alloc: &A) -> LocalApic

where A: Alloc<Size4Kb>,

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.

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

Formats the value using the given formatter.
