This is for the reason that 'dpdk-lcore-mask' hasn't been specified in the above case. If one specify dpdk-lcore-mask=<mask>, all the threads(revalidator/handler/ovs-vswitchd/urc) will automatically be pinned to the lowest core of the 'mask'. For example with 'ovs-vsctl --no-wait set Open_vSwitch . other_config:dpdk-lcore-mask=f00', I would expect the threads to float between cores 8 and 11, but all the threads get pinned to lowest core of the core-mask which is core 8. Hope this clears the confusion. $ ps -eLo tid,psr,comm | grep -e revalidator -e handler -e ovs -e pmd -e urc -e eal 98443 22 ovsdb-server 98454 8 ovs-vswitchd 98465 8 eal-intr-thread 98471 8 urcu3 98520 8 handler60 98521 8 handler59 98522 8 handler58 98523 8 handler57 98524 8 handler43 98525 8 handler44 98526 8 handler46 98527 8 handler47 98528 8 handler48 98529 8 handler41 98530 8 handler55 98531 8 handler49 98532 8 handler33 98533 8 handler40 98534 8 handler34 98535 8 handler35 98536 8 handler50 98537 8 handler36 98538 8 handler51 98539 8 handler56 98540 8 revalidator37 98541 8 revalidator52 98542 8 revalidator42 98543 8 revalidator38 98544 8 revalidator39 98545 8 revalidator45 98546 8 revalidator53 98547 8 revalidator54 98549 4 pmd61 Regards, Bhanu Prakash. > > >-- >Christian Ehrhardt >Software Engineer, Ubuntu Server >Canonical Ltd >_______________________________________________ >dev mailing list >dev@openvswitch.org >http://openvswitch.org/mailman/listinfo/dev _______________________________________________ dev mailing list dev@openvswitch.org http://openvswitch.org/mailman/listinfo/dev
