[Qemu-devel] [PATCH v4 0/8] virtio-rng refactoring.

[fred.konrad@greensocs.com]

From: KONRAD Frederic <fred.konrad@greensocs.com>

Acked-by: Amit Shah <amit.shah@redhat.com>

This is the last backend of the refactoring (*and must be applied at last,
because it would break virtio-9p*).

Basically it creates virtio-rng-device which extends virtio-device.
Then a virtio-rng-device can be connected on a virtio-bus.
virtio-rng-pci, virtio-rng-s390, virtio-rng-ccw are created too, they extend
respectively virtio-pci, virtio-s390-device, virtio-ccw-device and have a
virtio-rng-device.

When rng option is NULL, a default rng backend is created as before. But after
this refactoring, this default-backend will be the child of virtio-rng-device
instead of virtio-rng-*.

You can checkout my branch here:

git://project.greensocs.com/qemu-virtio.git virtio-rng-v4

Note that it is nearly the same series as virtio-blk and virtio-scsi
refactoring, and is rebased on top of virtio-9p-v3 I posted before.

I made basic tests (with linux guests) on:
 * qemu-system-i386

Cornelia tested it on s390 and ccw.

Changes v3 -> v4:
    * Remove some QOM casts on opaque.
    * Fix the commit message of the last patch.
    * Rebased.
Changes v2 -> v3:
    * Added CCW device.
    * Changes name: "virtio-rng" => "virtio-rng-device".
    * Rebased.

Thanks,

Fred
