Struct IntId 

pub struct IntId(/* private fields */);

An interrupt ID.

Implementations

impl IntId

pub const SPECIAL_SECURE: Self

Special interrupt ID returned when running at EL3 and the interrupt should be handled at S-EL2 or S-EL1.

pub const SPECIAL_NONSECURE: Self

Special interrupt ID returned when running at EL3 and the interrupt should be handled at (non-secure) EL2 or EL1.

pub const SPECIAL_NMI: Self

Special interrupt ID returned when the interrupt is a non-maskable interrupt.

pub const SPECIAL_NONE: Self

Special interrupt ID returned when there is no pending interrupt of sufficient priority for the current security state and interrupt group.

pub const MAX_SPI_COUNT: u32 = 988u32

The maximum number of SPIs which may be supported.

pub const SGI_COUNT: u32 = 16u32

The number of Software Generated Interrupts.

pub const PPI_COUNT: u32 = 16u32

The number of (non-extended) Private Peripheral Interrupts.

pub const MAX_EPPI_COUNT: u32 = 64u32

The maximum number of extended Private Peripheral Interrupts which may be supported.

pub const MAX_ESPI_COUNT: u32 = 1_024u32

The maximum number of extended Shared Peripheral Interrupts which may be supported.

pub const fn sgi(sgi: u32) -> Self

Returns the interrupt ID for the given Software Generated Interrupt.

pub const fn ppi(ppi: u32) -> Self

Returns the interrupt ID for the given Private Peripheral Interrupt.

pub const fn spi(spi: u32) -> Self

Returns the interrupt ID for the given Shared Peripheral Interrupt.

pub const fn eppi(eppi: u32) -> Self

Returns the interrupt ID for the given extended Private Peripheral Interrupt.

pub const fn espi(espi: u32) -> Self

Returns the interrupt ID for the given extended Shared Peripheral Interrupt.

pub const fn lpi(lpi: u32) -> Self

Returns the interrupt ID for the given Locality-specific Peripheral Interrupt.

pub const fn is_sgi(self) -> bool

Returns whether this interrupt ID is for a Software Generated Interrupt.

pub const fn is_ppi(self) -> bool

Returns whether this interrupt ID is for a Private Peripheral Interrupt.

pub const fn is_eppi(self) -> bool

Returns whether this interrupt ID is for an Extended Private Peripheral Interrupt.

pub const fn is_spi(self) -> bool

Returns whether this interrupt ID is for a Shared Peripheral Interrupt.

pub const fn is_espi(self) -> bool

Returns whether this interrupt ID is for an Extended Shared Peripheral Interrupt.

pub const fn is_private(self) -> bool

Returns whether this interrupt ID is private to a core, i.e. it is an SGI, PPI or EPPI.

pub const fn sgi_index(self) -> Option<u32>

Returns SGI index or None if it is not an SGI interrupt ID.

pub const fn private_index(self) -> Option<usize>

Maps SGI, PPI and EPPI interrupt IDs into a continuous index range starting from 0, making it ideal for indexing redistributor registers.

pub const fn espi_index(self) -> Option<usize>

Returns ESPI index or None if it is not an ESPI interrupt ID.

pub fn private() -> impl Iterator<Item = IntId>

Returns an array of all interrupt Ids that are private to a core, i.e. SGIs and PPIs.

pub fn spis() -> impl Iterator<Item = IntId>

Returns an array of all SPI Ids.

Trait Implementations

impl Clone for IntId

fn clone(&self) -> IntId

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for IntId

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

Formats the value using the given formatter.

impl From<IntId> for u32

fn from(intid: IntId) -> Self

Converts to this type from the input type.

impl Ord for IntId

fn cmp(&self, other: &IntId) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

impl PartialEq for IntId

fn eq(&self, other: &IntId) -> 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 PartialOrd for IntId

fn partial_cmp(&self, other: &IntId) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

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

Tests less than (for self and other) and is used by the < operator.

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

Tests less than or equal to (for self and other) and is used by the <= operator.

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

Tests greater than (for self and other) and is used by the > operator.

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

Tests greater than or equal to (for self and other) and is used by the >= operator.
