Thanks Fabien,
Now, as a side question, could you tell me which reference LEON3
platform is implemented by Qemu in leon3_generic?
It doesn't seem to match the one emulated by tsim.
Thanks.

Thanks Jean-Christophe,
With the LEON3 IRQ controller IRQs can be acknoledged 2 ways:
* Explicitely by software writing to the CLEAR_OFFSET register
* Implicitely when the procesor is done running the trap handler attached
to the IRQ.
The actual IRQMP code only allows the implicit processor triggered IRQ ack.
