From: Tonghao Zhang <xiangxia.m....@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.toshi...@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 drivers/vhost/net.c | 168 +++++++++++++++++++++++++++++++------------------- drivers/vhost/vhost.c | 24 +++----- 2 files changed, 113 insertions(+), 79 deletions(-) -- 1.8.3.1 _______________________________________________ Virtualization mailing list Virtualization@lists.linux-foundation.org https://lists.linuxfoundation.org/mailman/listinfo/virtualization
