Struct mnemos_d1_core::plic::Plic

pub struct Plic {
    plic: PLIC,
}

Platform-Level Interrupt Controller (PLIC) interface

Fields

plic: PLIC

Implementations

impl Plic

pub fn new(plic: PLIC) -> Self

Create a new Plic from the PLIC peripheral

pub unsafe fn summon() -> Self

Obtain a static Plic instance for use in e.g. interrupt handlers

Safety

’Tis thine responsibility, that which thou doth summon.

pub unsafe fn unmask(&self, interrupt: Interrupt)

Enable an interrupt

Safety

May effect normal interrupt processing

pub fn mask(&self, interrupt: Interrupt)

Disable an interrupt

pub unsafe fn set_priority(&self, interrupt: Interrupt, priority: Priority)

Globally set priority for one interrupt

Safety

May effect normal interrupt processing

pub fn claim(&self) -> Interrupt

pub unsafe fn dispatch_interrupt(&self)

Dispatch an interrupt to a vectored handler.

Safety

Should only be called in an ISR such as MachineInternal!

pub fn complete(&self, interrupt: Interrupt)

pub unsafe fn register(&self, interrupt: Interrupt, new_hdl: fn())

pub unsafe fn activate( &self, interrupt: Interrupt, prio: Priority, ) -> Result<(), MaskError>

pub fn deactivate(&self, interrupt: Interrupt) -> Result<(), MaskError>

fn can_mask(&self, interrupt: Interrupt) -> Result<(), MaskError>

fn index_mie(&self, interrupt: Interrupt) -> (&MIE, u32)
