Struct zircon_object::dev::Interrupt

pub struct Interrupt { /* fields omitted */ }

Interrupts - Usermode I/O interrupt delivery.

SYNOPSIS

Interrupt objects allow userspace to create, signal, and wait on hardware interrupts.

Implementations

impl Interrupt

pub fn new_virtual() -> Arc<Self>

Create a new virtual interrupt.

pub fn new_physical(
    vector: usize,
    options: InterruptOptions
) -> ZxResult<Arc<Self>>

Create a new physical interrupt.

pub fn new_pci(
    device: Arc<dyn IPciNode>,
    vector: u32,
    maskable: bool
) -> ZxResult<Arc<Self>>

Create a new PCI interrupt.

pub fn bind(&self, port: &Arc<Port>, key: u64) -> ZxResult

Bind the interrupt object to a port.

pub fn unbind(&self, port: &Arc<Port>) -> ZxResult

Unbind the interrupt object from a port.

Unbinding the port removes previously queued packets to the port.

pub fn trigger(&self, timestamp: i64) -> ZxResult

Triggers a virtual interrupt object.

pub fn ack(&self) -> ZxResult

Acknowledge the interrupt and re-arm it.

pub fn destroy(&self) -> ZxResult

Destroy the interrupt.

pub async fn wait(self: &Arc<Self>) -> ZxResult<i64>

Wait until the interrupt is triggered.

Trait Implementations

impl Debug for Interrupt

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

Formats the value using the given formatter.

impl Drop for Interrupt

fn drop(&mut self)

Executes the destructor for this type.

impl KernelObject for Interrupt

fn id(&self) -> KoID

Get object’s KoID.

fn type_name(&self) -> &str

Get the name of the type of the kernel object.

fn name(&self) -> String

Get object’s name.

fn set_name(&self, name: &str)

Set object’s name.

fn signal(&self) -> Signal

Get the signal status.

fn signal_set(&self, signal: Signal)

Assert signal.

fn signal_clear(&self, signal: Signal)

Deassert signal.

fn signal_change(&self, clear: Signal, set: Signal)

Change signal status: first clear then set indicated bits.

fn add_signal_callback(&self, callback: SignalHandler)

Add callback for signal status changes.

fn get_child(&self, _id: KoID) -> ZxResult<Arc<dyn KernelObject>>

Attempt to find a child of the object with given KoID.

fn peer(&self) -> ZxResult<Arc<dyn KernelObject>>

Attempt to get the object’s peer.

fn related_koid(&self) -> KoID

If the object is related to another (such as the other end of a channel, or the parent of a job), returns the KoID of that object, otherwise returns zero.

fn allowed_signals(&self) -> Signal

Get object’s allowed signals.
