Hi,

i have a general question about interrupt handling on a at91sam9263 
machine.
Is there a possibility to define a  GPIO Pin to register a interrupt 
handler and use
a interrupt service routine in the user space or should i use a RTDM modul.

Thomas

The way GPIO irqs are mapped to irq numbers is platform dependent.
Aside of that, once you have got the IRQ number, GPIO irqs are
considered as normal IRQs by Xenomai.
