IrqWorkerWaiter

Struct IrqWorkerWaiter 

Source
pub struct IrqWorkerWaiter { /* private fields */ }
Expand description

Fixed-owner waiter for one hard-IRQ notification cell.

The IRQ registration and the scheduler park transaction are the only two ownership edges. The waiter deliberately does not enqueue the same thread in a second task wait queue: a direct IRQ wake already targets the park generation owned by the scheduler.

Implementations§

Source§

impl IrqWorkerWaiter

Source

pub fn new(wake_owner: ThreadWakeHandle) -> Self

Binds a reusable IRQ registration to one fixed scheduler thread.

Source

pub fn wait(&self, event: &IrqWaitCell) -> Result<(), TaskError>

Waits until the cell consumes one pending or concurrent notification.

Unrelated scheduler wakes are retried without republishing the IRQ registration. This is the same fixed-waiter ownership used by Linux completion workers: the producer wakes the scheduler task directly and the scheduler remains the sole owner of its blocked/runnable state.

Source

pub fn wait_timeout( &self, event: &IrqWaitCell, timeout: Duration, ) -> Result<bool, TaskError>

Waits until notification or a relative timeout expires.

The timeout path retains the generic wait-queue race arbitration until the IRQ registration exposes a typed notify-versus-timeout outcome. The unbounded completion hot path uses Self::wait and owns no detached task wait queue.
