Required Methods

fn bsp(&self) -> bool

Is a bootstrap processor?

fn id(&self) -> u32

Return APIC ID.

fn logical_id(&self) -> u32

Returns the logical APIC ID.

fn version(&self) -> u32

Read APIC version

fn eoi(&mut self)

End Of Interrupt – Acknowledge interrupt delivery.

fn tsc_enable(&mut self, vector: u8)

Enable TSC deadline timer.

fn tsc_set(&self, value: u64)

Set TSC deadline value.

unsafe fn ipi_init(&mut self, core: ApicId)

Send a INIT IPI to a core.

Safety

Should only be used to reset or boot a new core.

unsafe fn ipi_init_deassert(&mut self)

Deassert INIT IPI.

Safety

Should only be used to reset or boot a new core.

unsafe fn ipi_startup(&mut self, core: ApicId, start_page: u8)

Send a STARTUP IPI to a core.

Safety

Should only be used to reset or boot a new core.

unsafe fn send_ipi(&mut self, icr: Icr)

Send a generic IPI.

Safety

Interrupts one or multiple cores.
