Expand description

API of interrupt types used by VirtIO devices

Required Methods§

Source

fn trigger( &self, interrupt_type: VirtioInterruptType, ) -> Result<(), InterruptError>

Trigger a VirtIO interrupt.

Source

fn status(&self) -> Arc<AtomicU32>

Get the current device interrupt status.

Provided Methods§

Source

fn trigger_queues(&self, queues: &[u16]) -> Result<(), InterruptError>

Trigger multiple Virtio interrupts for selected queues. The caller needs to ensure that [queues] does not include duplicate entries to avoid sending multiple interrupts for the same queue. This is to allow sending a single interrupt for implementations that don’t distinguish different queues, like IrqTrigger, instead of sending multiple same interrupts.
