This requirement is for a use case where we are running Intel Flexran software in a Kuberenetes pod. The Intel Flexran software requires that a u-plane VLAN is assigned to a VF and passed as u-plane VF to the software command line. Similarly, a c-plane VLAN needs to be assigned to a VF and passed as c-plane VF to the software command line. The SR-IOV daemon set supports this configuration: { "resourceName": "intel_sriov_dpdk_cplane", "resourcePrefix": "radisys.com", "selectors": { "rootDevices": [ "0000:18:00.3#4-7" ], "drivers": [ "igb_uio" ] } }, { "resourceName": "intel_sriov_dpdk_uplane", "resourcePrefix": "radisys.com", "selectors": { "rootDevices": [ "0000:18:00.3#0-3" ], "drivers": [ "igb_uio" ] } } In order to achieve this we followed the below steps in StarlingX Create Datanetworks for C and U plane traffic $ system datanetwork-add datanet-u -m 9216 vlan $ system datanetwork-add datanet-c -m 9216 vlan $ system host-if-modify -m 9216 -n sriovfh1 -c pci-sriov -N 8 --vf-driver=vfio controller-0 enp177s0f3 $ system interface-datanetwork-assign controller-0 sriovfh1 datanet-u $ system interface-datanetwork-assign controller-0 sriovfh1 datanet-c And we ended up in getting 2 resource lists (one for the C-PLANE and U-PLANE) but both of them containing the same list of VFs. Is there a way I can configure separate VFs for both the resource list that I shown in the above example?. In a standard Kubernetes deployment I would directly change the configmap & re-run the SRIOV daemon set. How can do this in StarlingX and does any System API support this? $ cat /etc/pcidp/config.json { "resourceName": "pci_sriov_net_datanet_up", "selectors": { "vendors": [ "8086" ], "drivers": [ "vfio-pci" ], "devices": [ "154c" ], "pfNames": [ "enp177s0f3#0,1,2,3,4,5,6,7" ] } }, { "resourceName": "pci_sriov_net_datanet_cp", "selectors": { "vendors": [ "8086" ], "drivers": [ "vfio-pci" ], "devices": [ "154c" ], "pfNames": [ "enp177s0f3#0,1,2,3,4,5,6,7" ] } }, Venkata Veldanda
