Thanks for the reply Richard. The interrupt is not a GPIO pin. I have read something about UIO (userspace I/O). Also, I want the operation to be asynchronous. Any pointer to such mechanism will be very helpful. Regards, Amit.

Hello, I am using a custom ARM board. I have a SPI slave device and using the spidev_test utility I am able to do ioctls on the slave device. However, I have a problem. The SPI slave device has an interrupt pin and I want to process the interrupt and send some data into the userspace when I receive the interrupt. Can anybody please suggest me a way to do this using spidev driver?
Is the interrupt pin a gpio? If so, you can access it from userspace and identify interrupts using poll(). -- Thanks, //richard _______________________________________________ Kernelnewbies mailing list Kernelnewbies@kernelnewbies.org http://lists.kernelnewbies.org/mailman/listinfo/kernelnewbies
