Hi Thomas, So from the OVS point of view, one of challenges when consuming DPDK is ens= uring device compatibility across the community, in particular with the ong= oing/upcoming HWOL development work. There is a risk that the implementatio= n for HWOL for vendor x may not be compatible or suitable for vendor y etc. To help address this risk, it was proposed back in DPDK userspace 2018 that= if the OVS community could provide a server, it could be used to co-locate= a variety of vendor NICs. We could then leverage the OVS Zero Day robot to= apply and conduct functional testing for OVS development patches and ensur= e patches do not break existing functionality. To date Aaron has received a number of NICs from various vendors, however a= server (possibly 2) would still be needed to deploy the NICS. It was proposed that possibly the DPDK Lab in UNL aid with this. The aim here is purely functional and the system would not be used to bench= mark the NICs in question. It would be purely to stop regressions being int= roduced into OVS DPDK and also act as a feedback to the DPDK community if c= hanges were needed in DPDK itself. It might be possible to run the tests on the existing hardware in UNL but I= guess this might not cover the NIC vendors Aaron has received to date. I w= onder would it interrupt the existing DPDK workloads on those servers also = so there was an open question on whether OVS DPDK should be deployed on a s= eparate board. @Aaron, have I missed anything from your side? Thanks Ian
