interrupt type from user mode

Dear experts

I have to make changes to a project developed years ago with arm 
architecture (atmel AT91SAM9G20) with linux 2.6.30 and xenomai 2.5.4.

The program uses a xenomai application in user mode and is connected to an 
interrupt (IRQ0).

I should reprogram the interrupt controller to receive interrupt on the 
rising edge, but I did not understand if this is possible from Xenomai 
user mode.
I know that I should develop an RTDM project but I'm trying to reuse a 
code already written that was entirely in user mode.

Thanks in advance
