Struct PLIC 

pub struct PLIC;

PLIC peripheral

Implementations

impl PLIC

pub fn is_interrupting() -> bool

Returns true if a machine external interrupt is pending.

pub fn is_enabled() -> bool

Returns true if Machine External Interrupts are enabled.

pub unsafe fn enable()

Enables machine external interrupts to allow the PLIC to trigger interrupts.

Safety

Enabling the PLIC may break mask-based critical sections.

pub fn disable()

Disables machine external interrupts to prevent the PLIC from triggering interrupts.

pub fn priorities() -> PRIORITIES

Returns the priorities register of the PLIC.

pub fn pendings() -> PENDINGS

Returns the pendings register of the PLIC.

pub fn ctx<H>(hart_id: H) -> CTX<PLIC>

where H: HartIdNumber,

Returns the context proxy of a given PLIC HART context.

pub fn ctx_mhartid() -> CTX<PLIC>

Returns the PLIC HART context for the current HART.

Note

This function determines the current HART ID by reading the riscv::register::mhartid CSR. Thus, it can only be used in M-mode. For S-mode, use PLIC::ctx instead.

impl PLIC

pub fn ctx0() -> CTX<PLIC>

Returns a PLIC context proxy for context of HART 0 .

Trait Implementations

impl Clone for PLIC

fn clone(&self) -> PLIC

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for PLIC

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

Formats the value using the given formatter.

impl PartialEq for PLIC

fn eq(&self, other: &PLIC) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl Plic for PLIC

const BASE: usize = 201_326_592usize

Base address of the PLIC peripheral.
