...t;dev, rvq)) {
vhost_poll_queue(&rvq->poll);
} else if (unlikely(vhost_enable_notify(&net->dev, rvq))) {
vhost_disable_notify(&net->dev, rvq);
vhost_poll_queue(&rvq->poll);
}
}
Also it's better to care vhost_net_disable_vq()/vhost_net_enable_vq() on tx?

[PATCH v2 net-next 0/4] vhost_net: Avoid vq kicks during busyloop
...5.43
Recv 4.17 5.26
TCP_STREAM 8801.03 45794 9592.77 2884

- Split patches into 3 parts (renaming variables, tx-kick fix, rx-wakeup
fix).
- Avoid rx-kicks too (patch 4).
- Don't memorize endtime as it is not needed for now.
Toshiaki Makita (4):
vhost_net: Rename local variables in vhost_net_rx_peek_head_len
vhost_net: Avoid tx vring kicks during busyloop
vhost_net: Avoid rx queue wake-ups during busypoll
vhost_net: Avoid rx vring kicks during busyloop
