DMA transfer between Jetson TX2 and PCIe

hi,We have a working design of a Xilinx FPGA connect with TX2 over PCIe 4x1,Can we use TX2 DMA engines in PCIE?Or must implement a DMA engine on the FPGA?

We suggest program your device as a v4l2 device so that you can put put frames in NvBuffers. Please refer to the sample tegra_multimedia_api\samples\12_camera_v4l2_cuda and tegra_multimedia_api\samples\v4l2cuda
