Subject: [Xenomai-core] Missing IRQ end function on PowerPC
Date: Wed, 18 Jan 2006 11:44:56 +0100	[thread overview]
Message-ID: <43CE1C28.6060001@domain.hid> (raw)

Hello,

with RTnet over Xenomai and Linux 2.4 on PowerPC I realized that Xenomai 
does not distinguish between a normal IRQ enable and an IRQ unmask at 
the end of an ISR (to reenable the IRQ). In the latter case the IRQ 
should be enabled on PowerPC as shown:

    if (rthal_irq_descp(irq)->handler->end != NULL)
  	   rthal_irq_descp(irq)->handler->end(irq);
     else
	   rthal_irq_descp(irq)->handler->enable(irq);

To handle this case properly, we need to different functions, I think.

Wolfgang.
