Trait ThreadedHandler

pub trait ThreadedHandler: Sync {
    // Required method
    fn handle_threaded(&self, device: &Device<Bound>) -> IrqReturn;

    // Provided method
    fn handle(&self, device: &Device<Bound>) -> ThreadedIrqReturn { ... }
}

Callbacks for a threaded IRQ handler.

Required Methods

fn handle_threaded(&self, device: &Device<Bound>) -> IrqReturn

The threaded IRQ handler.

This is executed in process context. The kernel creates a dedicated kthread for this purpose.

Provided Methods

fn handle(&self, device: &Device<Bound>) -> ThreadedIrqReturn

The hard IRQ handler.

This is executed in interrupt context, hence all corresponding limitations do apply. All work that does not necessarily need to be executed from interrupt context, should be deferred to the threaded handler, i.e. ThreadedHandler::handle_threaded.

The default implementation returns ThreadedIrqReturn::WakeThread.
