Hi Raghav, I suppose you are using Cyclone V SOC ARM, this way you can access fabric accessing memory mapped peripheral from user space in first then write a kernel device driver if your IP need be accessed as a system peripheral, both way plan to correctly map IP core to CPU address space. 

Please add details about what do you need to do with your Linux code and IP. 

Best regards
