Hi,
I submit this RFC to be sure I'm doing the right thing about the VirtioBus.
I push the patchset here :
git://git.greensocs.com/qemu_virtio.git virtio_refact
What I proposed to do :
* Introduce a new VirtioBus ( same way as scsi-bus.c ), with VirtIODevice
interface :
-> callback to completely abstract the VirtioDevice from VirtioPCI.
-> for the queue, load/save the queue/config, features, ..., other ?
* Add a VirtioBus to the VirtioPCIProxy. ( virtio-pci.c ) :
-> moving all to the newer callback.
* For each of the virtio-device : ( virtio-x.c )
-> making a separate class for virtio-x which is a VirtioDevice.
-> making a virtio-x-pci which has a virtio-x.
* Create virtio-mmio ( virtio-mmio.c ).
What it is done in this RFC :
* introduce VirtioBus, which can be added to Virtio transports like
virtio-pci or virtio-mmio. I think the interface must be improved.
* add a VirtioBus to the existing VirtioPCIProxy ( virtio-pci ), and add a
"virtio-pci" device which can be loaded without a VirtIODevice, and create
a VirtioBus.
* add a "virtio-blk" device which must be connected on a virtio-bus, to try
the virtio-bus and virtio-pci.
The info qtree return this structure :
bus: main-system-bus
type System
dev: i440FX-pcihost, id ""
bus: pci.0
type PCI
dev: virtio-pci, id ""
bus: virtio.0
type VIRTIO
dev: virtio-blk, id ""
What I must improve :
* the Virtio-PCI still need the VirtIODevice.
* others devices.
* spliting virtio-x-pci to virtio-x + virtio-pci.
Did I miss something ?
Thanks,
Fred.
