2009-07-30Remove the virtio-{blk, console}-pci-0-10 device typesMark McLoughlin
These are now unused. However, perhaps the idea is that when we add -device, they will be useful? In that case, we should add virtio-net-pci-0-10 too. Signed-off-by: Mark McLoughlin <markmc@redhat.com> Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>
2009-07-16qdev/compat: virtio-net-pci 0.10 compatibility.Gerd Hoffmann
Add vectors property, allowing to turn off msi by setting vectors=0. Add compat property to pc-0.10 disabling msi. Signed-off-by: Gerd Hoffmann <kraxel@redhat.com> Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>
2009-07-16qdev/compat: virtio-console-pci 0.10 compatibility.Gerd Hoffmann
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. Signed-off-by: Gerd Hoffmann <kraxel@redhat.com> Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>
2009-07-16qdev/compat: virtio-blk-pci 0.10 compatibility.Gerd Hoffmann
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. Signed-off-by: Gerd Hoffmann <kraxel@redhat.com> Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>

2009-07-16Change default PCI class of virtio-console to PCI_CLASS_SERIAL_OTHERMark McLoughlin
We're using PCI_CLASS_DISPLAY_OTHER now, but qemu-kvm.git is using PCI_CLASS_OTHERS because: "As a PCI_CLASS_DISPLAY_OTHER, it reduces primary display somehow on Windows XP (possibly Windows disables acceleration since it fails to find a driver)." While this is valid, many versions of X will get confused by it. Class major number of 0 gets treated as a possibly prehistoric VGA device, and then the autoconfig logic gets confused trying to figure out whether the virtio console or the pv vga device are the real VGA. We should really set a proper class ID. 0x0780 (serial / other) seems most appropriate. This shouldn't require any kernel changes, the modalias for virtio looks like: alias: pci:v00001AF4d*sv*sd*bc*sc*i* so won't care what the base class or subclass are. It shows up in the guest as: 00:05.0 Communication controller: Qumranet, Inc. Virtio console A new qdev type is introduced to allow devices using the old class to be created for compatibility with qemu-0.10.x.

2009-07-16Change default PCI class of virtio-blk to PCI_CLASS_STORAGE_SCSIMark McLoughlin
Windows virtio driver cannot pass DTM (certification) tests while the storage class is PCI_CLASS_STORAGE_UNKNOWN. A new qdev type is introduced to allow devices using the old class to be created for compatibility with qemu-0.10.x.

2009-07-10qemu/virtio: mark msi vectors used on loadMichael S. Tsirkin
Usage of msi vectors is controlled by the guest and so needs to be restored on load. Do this for msi vectors used by the virtio device. Signed-off-by: Michael S. Tsirkin <mst@redhat.com> Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>
2009-07-09qdev: update pci device registration.Gerd Hoffmann
Makes pci_qdev_register take a PCIDeviceInfo struct instead of a bunch of parameters. Also adds config_read and config_write callbacks to PCIDeviceInfo, so drivers needing these can be converted to the qdev device API too. Signed-off-by: Gerd Hoffmann <kraxel@redhat.com>
2009-06-29Revert "Introduce reset notifier order"Jan Kiszka
This reverts commit 8217606e6edb49591b4a6fd5a0d1229cebe470a9 (and updates later added users of qemu_register_reset), we solved the problem it originally addressed less invasively. Signed-off-by: Jan Kiszka <jan.kiszka@siemens.com> Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>
2009-06-24qemu/virtio: virtio save/load bindingsMichael S. Tsirkin
Implement bindings for virtio save/load. Use them in virtio pci. Signed-off-by: Michael S. Tsirkin <mst@redhat.com> Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>
2009-06-24qemu/virtio: MSI-X support in virtio PCIMichael S. Tsirkin
This enables actual support for MSI-X in virtio PCI. First user will be virtio-net. Signed-off-by: Michael S. Tsirkin <mst@redhat.com> Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>
2009-06-24qemu/virtio: virtio support for many interrupt vectorsMichael S. Tsirkin
Extend virtio to support many interrupt vectors, and rearrange code in preparation for multi-vector support (mostly move reset out to bindings, because we will have to reset the vectors in transport-specific code). Actual bindings in pci, and use in net, to follow. Load and save are not connected to bindings yet, so they are left stubbed out for now. Signed-off-by: Michael S. Tsirkin <mst@redhat.com> Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>
2009-06-22virtio: add support for indirect ring entriesMark McLoughlin
Support a new feature flag for indirect ring entries. These are ring entries which point to a table of buffer descriptors. The idea here is to increase the ring capacity by allowing a larger effective ring size whereby the ring size dictates the number of requests that may be outstanding, rather than the size of those requests. This should be most effective in the case of block I/O where we can potentially benefit by concurrently dispatching a large number of large requests. Even in the simple case of single segment block requests, this results in a threefold increase in ring capacity.

2009-06-16Rename pci_register_io_region() to pci_register_bar()Avi Kivity
This function is used to manage a PCI BAR, so make the more generic pci_register_io_region() available to other uses. Signed-off-by: Avi Kivity <avi@redhat.com> Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>
2009-05-19Hardware convenience libraryPaul Brook
The only target dependency for most hardware is sizeof(target_phys_addr_t). Build these files into a convenience library, and use that instead of building for every target. Remove and poison various target specific macros to avoid bogus target dependencies creeping back in. Big/Little endian is not handled because devices should not know or care about this to start with. Signed-off-by: Paul Brook <paul@codesourcery.com>
