Question about supported GPU cards for DPDK

Question about supported GPU cards for DPDK

[sakaia]

Hello

I have a question about (CUDA) DPDK supported GPU cards.
If this mailing list is not appropriate, please notice me an appropriate mailing list.

In my understanding, GPUDirect RDMA can use Tesla and Quadro cards.
Is this DPDK feature Tesla card only? 
Since it writes A100/A30/A10, V100, It does not describe Quadro series

It should work for any card supporting GPUDirect. The requirement is you
would need nv_peer_mem running, and this is now included in the latest
NVIDIA drivers.
