Michael Tsirkin updated VIRTIO-109:
-----------------------------------

        Summary: Reserve revisions > 1  (was: Reserve revisions > 1)
    Environment: &quot;Michael S. Tsirkin&quot; &lt;mst@redhat.com&gt;  (was: "Michael S. Tsirkin" <mst@redhat.com>)
    Description: 
If the proposed change to VIRTIO-102 is accepted,
devices can use all 16 bits of the subsystem device id for versioning. This makes it unnecessary to reserve revision ID for this purpose. Let&#39;s use it for the interface version again:
it served us in the 0.X -&gt; 1.X transition, will be handy for 1.X -&gt; 2.X as well.

       Proposal: 
Require that devices have revision &lt;= 1.
Require that drivers not match devices with revision &gt; 1.
