The interrupt from the gpiochip itself isn't registered at all ?! Hi Stephen, Did you export the gpio lines and set the edge in sysfs? Because the interrupts aren't allocated otherwise. For instance: root@socfpga_cyclone5:~# echo 195 > /sys/class/gpio/export root@socfpga_cyclone5:~# echo rising > /sys/class/gpio/gpio195/edge Now I can see a pretty nicely named interrupt in /proc/interrupts: 256: 0 0 gpio-dwapb 24 gpiolib Alan Tull Altera Corp -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
