Help with ISRs in Zephyr 😅 - Part Two

[alexpaschoaletto]

As a complement to discussion #88179, I'd really like to have some guidance on how to use ISRs for real in Zephyr. My specific question relates to the fact that the API describes means of enabling or disabling interrupts, as well as connecting and disconnecting ISRs with IRQs, but there is no described way of assigning a given event to an IRQ.

So basically, how do I set up the circumstance in which the IRQ will then be generated to trigger the ISR? The test suite has a trigger_irq function, for example, which is defined for various architectures and programmaticaly does that, but it clearly looks like an internal function for testing purposes only. I'd like to know the way of doing this in an actual application.
