Accessing PCIe port on the Xavier AGX via a C++ application

Hey,

I am making an application in which an FPGA Hardware (end point) device is going to send a large amount of data to my Xavier AGX(root complex) using the PCIe port. After receiving the data via a C++ application, the application than passes the data to the GPU of the AGX device for further processing.

Can the Xavier port be accessed via C++ or other drivers ?? If so, is there any example or tutorial regarding this ?

Thanks.
