They have\nbeen tested by intel QE which confirms the fix.\n\nPatch 3 aims at fixing interrupt mode.\n\nIn this v4, only changes are adding NULL check on the intr handle,\nto avoid segfault reproduced with using Virtio-user on the other end\nwhen quitting testpmd. It also add an error log when a valid kickfd\nget updated as suggested by David as it should not happen. Minor typos\nreported by David are also fixed.\n\nThere are still l3fwd-power flooding errors when leaving, but these\nwere already here in v20.05. This is an issue in the application,\nnot the PMD driver.\n\nThanks to Intel QE team for all the validation work!\nMaxime\n\n\nMaxime Coquelin (3):\n vhost: fix guest notification setting\n net/vhost: fix queue update\n net/vhost: fix interrupt mode\n\n drivers/net/vhost/rte_eth_vhost.c | 109 +++++++++++++++++++++++-------\n lib/librte_vhost/vhost.c | 24 +++++--\n lib/librte_vhost/vhost.h | 5 ++\n lib/librte_vhost/vhost_user.c | 11 ++-\n 4 files changed, 118 insertions(+), 31 deletions(-)" }
