In soc design examples (http://www.altera.com/support/examples/soc/soc.html) present many good examples for HPS developers with HWLIB on Baremetal way. 

We ask add to GPIO-example a possibility to work with FPGA buttons and its interrupts or make separate example. We try independently to make this -- no interrupt from 2 buttons !

I have the same situation. 

What i found that PIO core (the FPGA IP used fro push buttons) masked all interrupts. 

If you use the GHRD, unmask an interrupt. 

 

But still nothing move on HPS side :(
