Sorry I forgot the results...

when I run the application with RT_INTR_PROPAGATE :

$ cat /proc/ipipe/Xenomai
Priority=200, Id=0x58454e4f
irq0-1: grabbed
irq2-31: passed
irq32-33: passed, virtual
irq34: grabbed, virtual

$ cat /proc/ipipe/Linux
Priority=100, Id=0x00000000
irq0-15: accepted
irq32-33: grabbed, virtual
irq34: passed, virtual


when I run the application with RT_INTR_HANDLED

$ cat /proc/ipipe/Xenomai
Priority=200, Id=0x58454e4f
irq0-1: grabbed
irq2-31: passed
irq32-33: passed, virtual
irq34: grabbed, virtual

$ cat /proc/ipipe/Linux
Priority=100, Id=0x00000000
irq0-15: accepted
irq32-33: grabbed, virtual
irq34: passed, virtual

Thanks
