+pci spec says what width access to use for 32, 16 and 8
+bit fields, but does not explicitly say what to do for
+32 bit fields. As we have text that says driver must
+treat 64 bit accesses as non-atomic, this seems
+to imply driver should always do two 32 bit wide accesses.
+
+Let's make this an explicit requirement, and require

+multiple errors: Non-transitional With Legacy
+
+virtio 1.0 has two sections titled "Non-transitional Device With
+Legacy Driver" the first says devices SHOULD fail, the second
+says devices MUST fail.  Clearly a mistake.
+
+Other issues: devices don't really fail - they cause drivers to
+fail. second section seems to be in the wrong place, and also
+have a section followed by subsection with no explanatory text in
+between, which is ugly.
+Finally, this text was originally ritten to handle buggy windows
+drivers gracefully, but later we changed device IDs so it's not
+really required there. Might be handy for some other buggy legacy
+drivers, though no such drivers are known.
+
+To fix, drop the duplicate section variant, add some explanatory
+text, clarify what does "same ID" mean here, and clarify
+that the work-around is only needed if a buggy driver
+is known to bind to a transitional device.
+
+See \ref{sec:Virtio Transport Options / Virtio

+balloon: transitional device support
+
+Support a transitional balloon device: this has the advantage of supporting
+existing drivers, transparently, as well as transports that don't allow mixing
+virtio 0 and virtio 1 devices. And balloon is an easy device to test, so it's
+also useful for people to test virtio core handling of transitional devices.
+
+Three issues with legacy hypervisors have been identified:
+\begin{enumerate}
+\item
+Actual value is actually used, and is necessary for management
+to work. Luckily 4 byte config space writes are now atomic.
+When using old guests, hypervisors can detect access to the last byte.
+When using old hypervisors, drivers can use atomic 4-byte accesses.
+\item Hypervisors actually didn't ignore the stats from the first
+buffer supplied. This means the values there would be
+incorrect until hypervisor resends the request.
+Add a note suggesting hypervisors ignore the 1st buffer.
+\item QEMU simply over-writes stats from each buffer it gets.
+Thus if driver supplies a different subset of stats
+on each request, stale values will be there.
+Require drivers to supply the same subset on each
+request. This also gives us a simple way to figure out
+which stats are supported.
