Using Interrupt in Zynq Ultrascale+ MPSoC

Hi,
I’m new with freeRTOS and Zynq Ultrascale+ MPSoC. In a new project we switch from Virtex 5 PPC40 to Zynq Ultrascale+ MPSoC. So I have to port the old c++ firmware to the new processor.
I’m looking for information about the interrupt handling but I can’t find any documentation. What have I to do to use interrupts, ex. from PL to PS?
Thank you for your help.

This question does not seem to be for the FreeRTOS but for the specific hardware. I’d suggest you to contact the hardware vendor, Xilinx in this case.
