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 GitHub - NVIDIA/jetson-rdma-picoevb: Minimal HW-based demo of GPUDirect RDMA on NVIDIA Jetson AGX Xavier running L4T

Hi, vidyas was tested with Jetson AGX Xavier.
This document indicates that gpuDirectRDMA is supported by jetson AGX xavier.
Does gpuDirectRDMA also apply to jetsonTx2?
