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

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?
