Subject: [OASIS Issue Tracker] (VIRTIO-30) extend initialization sequence


     [ https://tools.oasis-open.org/issues/browse/VIRTIO-30?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Michael Tsirkin updated VIRTIO-30:
----------------------------------

             Assignee:     (was: Michael Tsirkin)
    Affects Version/s: virtio 0.9.X legacy
          Description: 
in the past we sometimes wanted an ability to make driver gracefully fail early in initialization
if it does not recognize/support a feature.
One such example we are introducing right now is the new VERSION_1 feature.

Drivers need to be able to add buffers before initialization is complete.

We also need a "lock point" after which drivers do not change features.
