i m using a pistachio L4 kernel. ( with no operating system on top. ) I am running this on an emulator ( qemu) . So i dont have a way of

how.
My question is : i figure there is an interrupt thread for every
interrupt.
? Since i dont have any real hardware i would like to have a interrupt thread for a random interrupt no. How do i make sure that this interrupt thread is created ? I am trying to simulate the behaviour of an
interrupt
processing in L4.
Why do you think that Qemu's interrupts are not real from the point of view of the software running on it?
I dont see any of L4's interrupt code path getting called, like irq_thread or handle_interrupt.
In any case when is an irq thread created ?
