qdev: add return value to init() callbacks.
Sorry folks, but it has to be. One more of these invasive qdev patches.
We have a serious design bug in the qdev interface: device initcallbacks can't signal failure because the init() callback has noreturn value. This patch fixes it....
virtio-blk: add msi support.
qdev/prop: convert virtio-pci.c to helper macros.

qdev-ify virtio-blk.
First user of the new drive property. With this patch applied hostand guest config can be specified separately, like this:
-drive if=none,id=disk1,file=/path/to/disk.img -device virtio-blk-pci,drive=disk1
You can set any property for virtio-blk-pci now. You can set the pci...
Remove the virtio-{blk, console}-pci-0-10 device types
These are now unused.
However, perhaps the idea is that when we add -device, they will beuseful? In that case, we should add virtio-net-pci-0-10 too.

qdev/compat: virtio-blk-pci 0.10 compatibility.
Add class property to virtio-blk-pci allowing to specify the PCI class.Add compat property to pc-0.10 to set the old PCI class.
qdev/compat: virtio-console-pci 0.10 compatibility.
Add class property to virtio-console-pci allowing to specify the PCI class.Add compat property to pc-0.10 to set the old PCI class.
qdev/compat: virtio-net-pci 0.10 compatibility.
Add vectors property, allowing to turn off msi by setting vectors=0.Add compat property to pc-0.10 disabling msi.
cleanup: drop unused struct elements from VirtIOPCIProxy.
Change default PCI class of virtio-blk to PCI_CLASS_STORAGE_SCSI
Windows virtio driver cannot pass DTM (certification) tests while thestorage class is PCI_CLASS_STORAGE_UNKNOWN.
A new qdev type is introduced to allow devices using the old classto be created for compatibility with qemu-0.10.x....
Change default PCI class of virtio-console to PCI_CLASS_SERIAL_OTHER
We're using PCI_CLASS_DISPLAY_OTHER now, but qemu-kvm.git is usingPCI_CLASS_OTHERS because:
"As a PCI_CLASS_DISPLAY_OTHER, it reduces primary display somehow on Windows XP (possibly Windows disables acceleration since it fails...
qemu/virtio: mark msi vectors used on load
Usage of msi vectors is controlled by the guest and so needs to berestored on load. Do this for msi vectors used by the virtio device.

qdev: update pci device registration.
Makes pci_qdev_register take a PCIDeviceInfo struct instead of a bunchof parameters. Also adds config_read and config_write callbacks toPCIDeviceInfo, so drivers needing these can be converted to the qdevdevice API too....
Revert "Introduce reset notifier order"
This reverts commit 8217606e6edb49591b4a6fd5a0d1229cebe470a9 (andupdates later added users of qemu_register_reset), we solved theproblem it originally addressed less invasively.

qemu/virtio: virtio save/load bindings
Implement bindings for virtio save/load. Use them in virtio pci.
qemu/virtio: virtio support for many interrupt vectors
Extend virtio to support many interrupt vectors, and rearrange code inpreparation for multi-vector support (mostly move reset out to bindings,because we will have to reset the vectors in transport-specific code)....
qemu/virtio: MSI-X support in virtio PCI
This enables actual support for MSI-X in virtio PCI.First user will be virtio-net.
virtio: add support for indirect ring entries
Support a new feature flag for indirect ring entries. These are ringentries which point to a table of buffer descriptors.
The idea here is to increase the ring capacity by allowing a largereffective ring size whereby the ring size dictates the number of...
Rename pci_register_io_region() to pci_register_bar()
This function is used to manage a PCI BAR, so make the more genericpci_register_io_region() available to other uses.
