Struct x86::apic::x2apic::X2APIC

pub struct X2APIC { /* private fields */ }

Represents an x2APIC driver instance.

Implementations

impl X2APIC

pub const fn new() -> Self

Create a new x2APIC driver object for the local core.

Notes

The object needs to be initialized by calling attach() first which enables the x2APIC. There should be only one x2APIC object created per core.

pub fn attach(&mut self)

Attach to APIC (enable x2APIC mode, initialize LINT0)

pub fn detach(&mut self)

Detach from APIC (disable x2APIC and xAPIC mode).

pub unsafe fn send_self_ipi(&self, vector: u64)

Send an IPI to yourself.

Safety

Will interrupt core with vector.

Trait Implementations
