[PATCH net-next v2] net: vhost: improve performance when enable busyloop
...m: Tonghao Zhang <xiangxia.m.yue at gmail.com>
This patch improves the guest receive performance from
host. On the handle_tx side, we poll the sock receive
queue at the same time. handle_rx do that in the same way.
For avoiding deadlock, change the code to lock the vq one
by one and use the VHOST_NET_VQ_XX as a subclass for
mutex_lock_nested. With the patch, qemu can set differently
the busyloop_timeout for rx or tx queue.
We set the poll-us=100us and use the iperf3 to test
its throughput. The iperf3 command is shown as below.
on the guest:
iperf3 -s -D
on the host:
iperf3 -c 192.168.1.100 -i 1...
