Hello,

 In my understanding, GPUDirect RDMA is supported on Tesla and Quadro/RTX.
 But following code only specifies Tesla.
 Is there any reason to specify in the code?

 List in the code
 https://github.com/DPDK/dpdk/blob/v22.03/drivers/gpu/cuda/cuda.c#L56-L71

 GPUDirect RDMA
  GPUDirect RDMA is available on both Tesla and Quadro GPUs.
 https://docs.nvidia.com/cuda/gpudirect-rdma/index.html

Thanks
Atsushi SAKAI

Hello,

I specified only the GPUs I was able to test.
You can always add your GPU model to the list in DPDK/drivers/gpu/cuda/cuda.c

Let me know if you have any issue

Thanks

Quick update: I tried to capture the majority of new GPUDirect RDMA GPU-compatible devices in a new DPDK patch.
Do you see any relevant GPU missing?
