Struct sunrise_kernel::event::IRQEvent

pub struct IRQEvent {
    state: &'static IRQState,
    ack: AtomicUsize,
}

An event waiting for an IRQ.

When created, is_signaled is called and the IRQ was triggered, it will increment the ACK count by 1. This means that if multiple IRQs happened between wait calls, it will immediately return true.

Fields

state: &'static IRQState

The global state of the IRQ this event is listening on. Contains the IRQ trigger count.

ack: AtomicUsize

Acknowledgement counter for this IRQEvent instance. Each time we get signaled, this counter is incremented until it matches the counter in state.
