Thanks for your input. But I dont want to block the read call. Also I dont want to miss the interrupts.

Look how other drivers/programs deal with that...

Thanks,

Amit.

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.

Using UIO you can also catch an interrupt in userspace.
You can have a read() which blocks till data is available.


Thanks,
