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?

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
