Create Interupt from HPS to NIOS II

Hello,

I have an application which transfers data from the HPS to a NIOS II. I would like to use an interrupt to signal to the NIOS II from the HPS that new data is available. How can I do this?

Many thanks.

    May will use FPGA-GPIO pins ? Question to all.

    Out pin to FPGA-LED may make request in Nios ?

    64 lines from FPGA to GIC with interrupts is unidirectional ?

    I personally recommend polling -- Nios read memory writing from HPS and see pointer changing.
