2015-07-08virtio-pci: implement cfg capabilityMichael S. Tsirkin1-0/+3
spec says we must, so let's do it! Note: the implementation is incorrect for BE targets. Will fix with a patch on top, not a big deal now as the only user is seabios, used on x86 only. Tested-by: Gerd Hoffmann <kraxel@redhat.com> Signed-off-by: Michael S. Tsirkin <mst@redhat.com>
2015-06-23virtio-input: evdev passthroughGerd Hoffmann1-0/+10
This allows to assign host input devices to the guest: qemu -device virtio-input-host-pci,evdev=/dev/input/event<nr> The guest gets exclusive access to the input device, so be careful with assigning the keyboard if you have only one connected to your machine.

2015-06-12virtio-gpu-pci: add virtio pci supportGerd Hoffmann1-0/+14
This patch adds virtio-gpu-pci, which is the pci proxy for the virtio gpu device. With this patch in place virtio-gpu is functional. You need a linux guest with a virtio-gpu driver though, and output will appear pretty late in boot, once the kernel initialized drm and fbcon. Written by Dave Airlie and Gerd Hoffmann.

2015-06-10virtio-input: emulated devices [pci]Gerd Hoffmann1-0/+13
This patch adds virtio-pci support for the emulated virtio-input devices. Using them is as simple as adding "-device virtio-tablet-pci" to your command line. If you want add multiple devices but don't want waste a pci slot for each you can compose a multifunction device this way: qemu -device virtio-keyboard-pci,addr=0d.0,multifunction=on \ -device virtio-tablet-pci,addr=0d.1,multifunction=on Signed-off-by: Gerd Hoffmann <kraxel@redhat.com> Reviewed-by: Michael S.

2015-06-10virtio-pci: fill VirtIOPCIRegions early.Gerd Hoffmann1-0/+4
Initialize the modern bar and the VirtIOPCIRegion fields early, in realize. Also add a size field to VirtIOPCIRegion and variables for pci bars to VirtIOPCIProxy. This allows virtio-pci subclasses to change things before the device_plugged callback applies them. virtio-vga will use that to arrange regions in a way that virtio-vga is compatible to both stdvga (in vga mode) and virtio-gpu-pci (in pci mode).

2015-06-10virtio-pci: add flags to enable/disable legacy/modernGerd Hoffmann1-0/+6
Add VIRTIO_PCI_FLAG_DISABLE_LEGACY and VIRTIO_PCI_FLAG_DISABLE_MODERN for VirtIOPCIProxy->flags. Also add properties for them. They can be used to disable modern (virtio 1.0) or legacy (virtio 0.9) modes. By default only legacy is advertized, modern will be turned on by default once all remaining spec compilance issues are addressed.

2015-06-10virtio-pci: initial virtio 1.0 supportMichael S. Tsirkin1-0/+16
This is somewhat functional. With this, and linux driver from my tree, I was able to use virtio net as virtio 1.0 device for light browsing. At the moment, dataplane and vhost code is still missing.

2015-05-31virtio: move host_featuresCornelia Huck1-1/+0
Move host_features from the individual transport proxies into the virtio device. Transports may continue to add feature bits during device plugging. This should it make easier to offer different sets of host features for virtio-1/transitional support.

2014-11-02virtio-pci: fix migration for pci bus masterMichael S. Tsirkin1-0/+5
Current support for bus master (clearing OK bit) together with the need to support guests which do not enable PCI bus mastering, leads to extra state in VIRTIO_PCI_FLAG_BUS_MASTER_BUG bit, which isn't robust in case of cross-version migration for the case when guests use the device before setting DRIVER_OK. Rip out this code, and replace it: - Modern QEMU doesn't need VIRTIO_PCI_FLAG_BUS_MASTER_BUG so just drop it for latest machine type. - For compat machine types, set PCI_COMMAND if DRIVER_OK is set. As this is needed for 2.1 for both pc and ppc, move PC_COMPAT macros from pc.h to a new common header. Cc: Greg Kurz <gkurz@linux.vnet.ibm.com> Signed-off-by: Michael S.

2014-07-01virtio-blk: use aliases instead of duplicate qdev propertiesStefan Hajnoczi1-1/+0
virtio-blk-pci, virtio-blk-s390, and virtio-blk-ccw all duplicate the qdev properties of their VirtIOBlock child. This approach does not work well with string or pointer properties since we must be careful about leaking or double-freeing them. Use the QOM alias property to forward property accesses to the VirtIOBlock child. This way no duplication is necessary. Remember to stop calling virtio_blk_set_conf() so that we don't clobber the values already set on the VirtIOBlock instance.
