Must be called hw IRQs off is a hardware register that we need to modify, or xenomai has a special function interface to make it meet the conditions. It was found that many function calls in xenomai limit Must be called hw IRQs off. What is the intention in the middle? 
looking forward to your reply, bless you

Currently I need to trigger an interrupt in the xenomai domain, respond in the xenomai domain, and then pass it to the linux domain and then respond. To verify the interrupt delivery function of ipipe, what should I do? Looking forward to your reply! bless you

root:ipipe_raise_irq(irq) -> head:ipipe_post_irq_root(irq) ->

ipipe_post_irq_root() must be called with hard IRQs off, which is the
case when called from a head stage IRQ handler.
