Subject: [PATCH 0/6] virtio_balloon: virtio 1 support
Date: Mon, 30 Mar 2015 19:37:08 +0200 [thread overview]
Message-ID: <1427737006-23191-1-git-send-email-mst__35242.6670644947$1427737052$gmane$org@redhat.com> (raw)
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
