Subject: [PATCH net-next v7 0/4] net: vhost: improve performance when enable busyloop
Date: Tue, 31 Jul 2018 20:00:50 -0700 [thread overview]
Message-ID: <1533092454-37196-1-git-send-email-xiangxia.m.yue@gmail.com> (raw)
From: Tonghao Zhang <xiangxia.m.yue@gmail.com>
This patches improve the guest receive performance.
On the handle_tx side, we poll the sock receive queue
at the same time. handle_rx do that in the same way.
For more performance report, see patch 4.
v6->v7:
fix issue and rebase codes:
1. on tx, busypoll will vhost_net_disable/enable_vq rx vq.
[This is suggested by Toshiaki Makita <makita.toshiaki@lab.ntt.co.jp>]
2. introduce common helper vhost_net_busy_poll_try_queue().
v5->v6:
rebase the codes.
Tonghao Zhang (4):
net: vhost: lock the vqs one by one
net: vhost: replace magic number of lock annotation
net: vhost: factor out busy polling logic to vhost_net_busy_poll()
net: vhost: add rx busy polling in tx path
