C++ Irq interface, see IRQs for the C interface.
The Irq class provides access to abstract interrupts provided by the microkernel. Interrupts may be
For hardware and virtual device interrupts the Irq object must be bound to an interrupt source, see L4::Icu. To receive interrupts, the Irq object must be bound to a thread, see L4::Rcv_endpoint.
Irq objects can be created using a factory, see the L4::Factory API (L4::Factory::create()).
For the C interface refer to the IRQs API for an overview.
