How to make Avalon Streaming data accessible to Avalon MM based PCie end point?

I want to interface a camera to a MIPI CSI2 IP core in cyclone V FPGA.The MIPI CSI2 IP core provide the data output in Avalon Streaming format, I need to pass the same data to the PCie end point.

The MIPI CSI2IP core's control registers are accessible through Avalon MM interface.

How to make the Avalon Streaming data available to the PCIe endpoint which have an Avalon MM interface?

is there any reference designs available?
