Direct access to the GPU memory over PCIe?

background:TX2 Jetpack4.2 endpoint:Xilinx Fpga
question: I’m use cuda module . Is it possible for the GPU to communicate with third-party devices via PCIE?

If RDMA is what you are asking for, please take a look at https://github.com/NVIDIA/jetson-rdma-picoevb

Hi, vidyas
https://github.com/NVIDIA/jetson-rdma-picoevb was tested with Jetson AGX Xavier.

https://docs.nvidia.com/cuda/gpudirect-rdma/index.html
This document indicates that gpuDirectRDMA is supported by jetson AGX xavier.
Does gpuDirectRDMA also apply to jetsonTx2?
