Member Function Documentation

void Virq::acknowledge (   )  [virtual]

Implements Irq_alloc.

bool Virq::alloc (  Receiver *  t, bool  )  [inline, virtual]

Bind a receiver to this virtual interrupt. Parameters: t  the receiver that wants to receive IPC messages for this IRQ ack_in_kernel  if true, the kernel will acknowledge the interrupt, as opposed to user-level acknowledgement Returns: true if the binding could be established Implements Irq_alloc.

bool Virq::free (  Receiver *  t  )  [inline, virtual]

Release an virtual interrupt. Parameters: t  the receiver that owns the IRQ Returns: true if t really was the owner of the IRQ and operation was successful Implements Irq_alloc.

void Virq::hit (   )  [inline]

The corresponding virtual interrupt occurred -- handle it. This method checks whether the attached receiver is ready to receive an IRQ message, and if so, restarts it so that it can pick up the IRQ message using ipc_receiver_ready().

void Virq::notify (   )  [inline, virtual]

Implements Observer.
