Subject: [Xenomai-help] Question about interrupt propagation to Linux
Date: Sat, 2 Sep 2006 13:49:16 +0200	[thread overview]

Hello,

I have a question about interrupt propagation to Linux with the
XN_ISR_PROPAGATE return value in the real-time interrupt handler.

My question is: is the particular IRQ (not other IRQs) that is handled
by this ISR re-enabled after the *RT* ISR finished or is it re-enabled
after the *Linux* ISR has finished. In my understanding the interrupt
cannot be enabled after the RT-ISR because then the RT-ISR handler
would be called again and the Linux ISR would never have a chance to
run.

Thanks.


Regards,
  Bernhard
