Mellanox OFED GPUDirect RDMA for AGX Xavier

I’m not sure if AGX kernel 4.9.140-tegra supports OFED GPUDirect RDMA but I followed this link anyway Mellanox OFED GPUDirect RDMA

I’m able to successfully install MLNX_OFED package as required by the user manual. Then I downloaded GPUDirect RDMA package nvidia-peer-memory_1.1.tar.gz, but then when I tried to build nv_peer_mem I got the following error:

CUDA driver must be installed before installing this package!

I have verified CUDA driver and devel packages are all installed. I’m not sure what I was missing.

That’s not support with Jetson AGX Xavier, but for NVIDIA® Tesla™ / Quadro K-Series or Tesla™ / Quadro™ P-Series GPU only.
