We have been testing the rebalance code in different situations while having traffic going through OVS. Those tests have shown that part of the observed packets losses is due to some time wasted in signaling/waiting for the pmd threads to reload their polling configurations.
This RFC series is an attempt at getting pmd threads reloads quicker and more deterministic. -- David Marchand David Marchand (5): dpif-netdev: Convert exit latch to flag. dpif-netdev: Trigger parallel pmd reloads. dpif-netdev: Do not sleep when swapping queues. dpif-netdev: Only reload static tx qid when needed. dpif-netdev: Catch reloads faster. lib/dpif-netdev.c | 122 ++++++++++++++++++++++++++++++++++++++++-------------- 1 file changed, 92 insertions(+), 30 deletions(-) -- 1.8.3.1 _______________________________________________ dev mailing list [email protected] https://mail.openvswitch.org/mailman/listinfo/ovs-dev
