Struct IntId 

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

A GIC interrupt identifier (raw INTID).

Use the named constructors to translate from FDT-cell offsets — never reach for a u32 directly. The internal value is the raw INTID: SPIs are 32..=1019, PPIs are 16..=31.

Implementations

impl IntId

pub const fn from_spi_intid(intid: u32) -> Result<Self, IntIdError>

Construct from a raw SPI INTID (32..=1019). For values written as cell-offsets in an FDT, prefer Self::from_spi_cell.

Errors

IntIdError::SpiOutOfRange if intid is outside the SPI range.

pub const fn from_ppi_intid(intid: u32) -> Result<Self, IntIdError>

Construct from a raw PPI INTID (16..=31).

Errors

IntIdError::PpiOutOfRange if intid is outside the PPI range.

pub const fn from_spi_cell(cell_offset: u32) -> Result<Self, IntIdError>

Construct an SPI from an FDT cell offset (raw INTID = 32 + offset).

Use this whenever you are reading or emitting an FDT — the cell number is what appears in the FDT text, the raw INTID is what the kernel and HVF speak.

Errors

IntIdError::SpiCellOffsetOutOfRange if 32 + cell_offset > SPI_INTID_MAX.

pub const fn from_ppi_cell(cell_offset: u32) -> Result<Self, IntIdError>

Construct a PPI from an FDT cell offset (raw INTID = 16 + offset).

Errors

IntIdError::PpiCellOffsetOutOfRange if cell_offset > 15.

pub const fn as_raw(self) -> u32

Raw INTID — what hv_gic_set_spi and friends consume.

pub const fn is_spi(self) -> bool

true if this is an SPI (32..=1019).

pub const fn is_ppi(self) -> bool

true if this is a PPI (16..=31).

pub const fn fdt_cell_type(self) -> u32

FDT cell type field (0 for SPI, 1 for PPI).

Errors

Returns the original IntIdError from the malformed branch — if self is neither a valid SPI nor PPI (which the constructors disallow), this is treated as an SPI out-of-range.

pub const fn fdt_cell_offset(self) -> u32

FDT cell offset (INTID − 32 for SPI, INTID − 16 for PPI).

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 Hash for IntId

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

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.
