Hello,
In __ipipe_handle_irq, there is a call to the function __ipipe_walk_pipeline() "that plays interrupts pending in the log", is it really the execution of the treatement linked to an interruption ?
If yes, what happens when there is a new interruption ? In fact, we know that Hw interrupts are off on entry. So, if a new interruption for a more prioritary domain comes during the execution of __ipipe_walk_pipeline() for a less prioritary domain, how __ipipe_walk_pipeline() is preempted ?
Cheers
Adrien Chiron & Vincent Vanbesien

Look for __ipipe_run_isr().
