GPUDirect Support for Jetson TX2 and TX2i

Does the GPU on the Jetson TX2/TX2i support GPUDirect? I want to build a custom board using the SoC or SoM in TX2/TX2i board. I am trying to stream RF IQ data points (very high volume - think GB/s) for real time analysis. Please state your source.

Hi babaali9966,

I don’t think TX2/TX2i has this capability, the GPUDirect RDMA is only supported on Jetson AGX Xavier, as it features cache coherency between CPU/GPU.
