Hi, I using DPDK with OVS and looking for a way to get interrupt based link state notifications for dpdk type ports. As its dpdk port, i believe netlink socket for RTMGRP_LINK is not going to work. what is the recommended way to get link state notifications for dpdk ports?
i came across "link status interrupt sample application", which is providing what i am looking for. http://dpdk.org/doc/guides-16. 04/sample_app_ug/link_status_intr.html How can i use this application along with openvswitch; should i write some code within ovs to register for ISR ? or is there a another way i can run this as a separate application without modifying ovs. when i tried to run OVS with dpdk and link status app, rte_config was locked by ovs. [root at localhost build]# ./link_status_interrupt -c f -n 4 -- -p ffff EAL: Detected lcore 0 as core 0 on socket 0 EAL: Detected lcore 1 as core 1 on socket 0 EAL: Detected lcore 2 as core 2 on socket 0 EAL: Detected lcore 3 as core 3 on socket 0 EAL: Detected lcore 4 as core 4 on socket 0 EAL: Detected lcore 5 as core 5 on socket 0 EAL: Detected lcore 6 as core 6 on socket 0 EAL: Detected lcore 7 as core 7 on socket 0 EAL: Support maximum 128 logical core(s) by configuration. EAL: Detected 8 lcore(s) EAL: Error - exiting with code: 1 Cause: Cannot create lock on '/var/run/.rte_config'. Is another primary process running? Thanks kapil.
