Struct IrqVectorRegistration 

Source 
pub struct IrqVectorRegistration<'a> { /* private fields */ }
Expand description

An allocation of PCI interrupt vectors for a device.

This type owns the vector allocation; dropping it frees the vectors. IRQ handlers borrow from this registration and must be dropped before it is.

§Invariants

dev has an allocation of len interrupt vectors.

Implementations§

Source§

impl<'a> IrqVectorRegistration<'a>

Source

pub fn len(&self) -> usize

Returns the number of allocated vectors.

This is at least the min_vecs that Device::alloc_irq_vectors was asked for.

Source

pub fn irq_type(&self) -> IrqType

Returns the interrupt type the PCI core selected for this allocation.

Source

pub fn index(&self, index: usize) -> Result<IrqVector<'_>>

Returns the IrqVector at index.

Returns EINVAL if the index is out of bounds for the length reported by Self::len().

Trait Implementations§
