Hello,

I'm trying to use ddd (connected to QEMU) to debug my own kernel and it works fine.

The only problem I have is that I'm always interrupted by my IRQ handlers (and especially the timer, IRQ 0).

Is there a way to avoid ddd to jump to my irq handlers functions so I can step into my code without being interrupted ?

I hope my english is good enough for you to understand  :)

Thanks

Greg

If you are trying to single-step, you should disable interrupts/timers when 
single stepping in Qemu GDB stub.
