Waking up user space application on buffer availability

I am currently using AD7606 with buffers & triggers enabled at the driver level. I am able to read the data in command line mode, I want to read the buffer continuously in user space whenever it's available.


Anyway where in I can wake up the thread in user space or perform read operation only when the sysfs entries for buffer is full.

I don't want to poll, I want to notify the user space program to perform read operation on the buffer based on availability.

Please give me some ideas on how to go about this.
