[v3,0/6] vhost: improve ready state

  Due to the issue described in "vhost: improve device ready definition"
patch here, we need to change the ready state definition in vhost device.

To support the suggestion improvement there is update for the host notifier control API.

Also need to skip access lock when vDPA device is configured.

Add also support for configuration change when the device is ready.

v3:
Rebase.
Add missing commit: vhost: support host notifier queue configuration.

Matan Azrad (6):
  vhost: support host notifier queue configuration
  vhost: skip access lock when vDPA is configured
  vhost: improve device readiness notifications
  vhost: handle memory hotplug with vDPA devices
  vhost: notify virtq file descriptor update
  vdpa/mlx5: support queue update

Applied to dpdk-next-virtio/master

Thanks,
Maxime
  

Hi Matan,

In our daily regression test, we found this patch set will decrease virtio performance and causes virtio interrupt not working properly in multi queue scenarios.  
Could you help to take a look?
Details in Bugzilla  https://bugs.dpdk.org/show_bug.cgi?id=507, btw, pls use low qemu version(qemu<4.1) to reproduce the second issue since the case blocked by one qemu bug with high qemu version.

BR,
Yinan
