Excellent. I can test when you have something. > Several people are interested, and John Fastabend told me he plans to : > > (1) rcu'ify classifiers/actions as needed Makes sense in most cases. If you have a lot of flow setup/teardown it may harm. Another one - but dont see how much you can do about this; useful when you want to share state (eg multiple flows being policed by a single rate meter); An action could be shared across multiple policies i.e you can have: match1, action foo instance 1, action bar instance 3 match2, action bar instance3 match3, .... This could would mean a lock contended across cpus when different flows hitting match1/2 show up on different cpus. > (2) add flag to drop qdisc lock on simple or hw qdiscs Where does config for the hardware happen from? > (3) mq and mqprio call root qdisc and run a pass over classifiers > actions possibly resetting queue_mapping. It seems to make sense - but I will wait and see to have better understanding. cheers, jamal _______________________________________________ dev mailing list dev@openvswitch.org http://openvswitch.org/mailman/listinfo/dev
