Virtio 1.0 doesn't include a modern balloon device.
At some point we'll likely define an incompatible interface with a different
ID. But for now, it's not a big change to support a transitional balloon
device: this has the advantage of supporting existing drivers, transparently.
The only issue is with the stats buffer, which has misaligned fields.
Seems easy to fix by prepending a 6 byte reserved field.
I'll post spec patch and qemu patches shortly.
Michael S. Tsirkin (6):
virtio_balloon: transitional interface
virtio: balloon might not be a legacy device
virtio_ccw: support non-legacy balloon devices
virtio_mmio: support non-legacy balloon devices
virtio_pci: support non-legacy balloon devices
virtio: drop virtio_device_is_legacy_only

We added transitional device support to balloon driver,
so we don't need to black-list it in core anymore.

Hmm, re-reading the code, this won't be enough for BE
guests. We are doing one extra byteswap there.
I'll fix up and repost.

This is needed to support a ballooner on transports that don't support
mixing legacy and 1.0, right?

That too. But it's also useful if you don't know whether your guest
supports virtio 1 or not - which is the point of using
a transitional device.
