Re: irq sharing not permitted - comedi's or RTLinux/RTAI's limitation?

Thanks for your reply,

  By the way, what time is it over there??

  I understand that neither the RTLinux or the RTAI allows more than one
realtime handler to be installed on a same irq (handler's address is
overwritten). But is it also a bad idea to share an irq by a realtime and
NON-realtime handlers (I have PCI-DAS1602/16, 3Com's NIC and a USB interface
on IRQ=9. I only want the handler for DAS1602 to be realtime)? If yes, could
you please explain why?
 Thanks in advance,
Tak
