Date: Mon, 30 Mar 2015 19:37:08 +0200 From: "Michael S. Tsirkin" <mst@...hat.com> To: linux-kernel@...r.kernel.org Cc: virtio-dev@...ts.oasis-open.org, virtualization@...ts.linux-foundation.org, Rusty Russell <rusty@...tcorp.com.au> Subject: [PATCH 0/6] virtio_balloon: virtio 1 support 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.
