2018-12-19virtio: Helper for registering virtio device typesEduardo Habkost1-4/+3
Introduce a helper for registering different flavours of virtio devices. Convert code to use the helper, but keep only the existing generic types. Transitional and non-transitional device types will be added by another patch.

2018-09-27display/stdvga: add edid support.Gerd Hoffmann1-1/+1
This patch adds edid support to the qemu stdvga. It is turned off by default and can be enabled with the new edid property. The patch also adds xres and yres properties to specify the video mode you want the guest use. Works only with edid enabled and updated guest driver. The mmio bar of the stdvga has some unused address space at the start. It was reserved just in case it'll be needed for virtio, but it turned out to not be needed for that. So let's use that region to place the EDID data block there. Signed-off-by: Gerd Hoffmann <kraxel@redhat.com> Message-id: 20180925075646.25114-6-kraxel@redhat.com

This reverts commit 93f874fe9dbe0b997b5a9459840957efd13d7191. Now with virtio-vga being resetted properly the crash workaround is not needed any more.

2018-08-07virtio-gpu: fix crashes upon warm reboot with vga modeMarc-André Lureau1-0/+11
With vga=775 on the Linux command line a first boot of the VM running Linux works fine. After a warm reboot it crashes during Linux boot. Before that, valgrind points out bad memory write to console surface. The VGA code is not aware that virtio-gpu got a message surface scanout when the display is disabled. Let's reset VGA graphic mode when it is the case, so that a new display surface is created when doing further VGA operations. https://bugs.launchpad.net/qemu/+bug/1784900/ Reported-by: Stefan Berger <stefanb@linux.vnet.ibm.com> Signed-off-by: Marc-André Lureau <marcandre.lureau@redhat.com> Reviewed-by: Michael S.

2018-07-03vga: disable global_vmstate for 3.0+ machine typesGerd Hoffmann1-1/+1
Move global_vmstate from vga_common_init() parameter to VGACommonState field. Set global_vmstate to true for isa vga devices, so nothing changes here. virtio-vga and secondary-vga already set global_vmstate to false so no change here either. All other pci vga devices get a new global-vmstate property, defaulting to false. A compat property flips it to true for older machine types. With this in place you don't get a vmstate section naming conflict any more when adding multiple pci vga devices to your vm.

2016-07-29hw/virtio-pci: fix virtio behaviourMarcel Apfelbaum1-3/+1
Enable transitional virtio devices by default. Enable virtio-1.0 for devices plugged into PCIe ports (Root ports or Downstream ports). Using the virtio-1 mode will remove the limitation of the number of devices that can be attached to a machine by removing the need for the IO BAR.

Switch over to virtio_instance_init_common. Drop duplicate properties in virtio-gpu-pci and virtio-vga as they are properly aliased now. Also drop the indirection via DEFINE_VIRTIO_GPU_PROPERTIES, we don't need it any more as the properties are defined in a single place now. Signed-off-by: Gerd Hoffmann <kraxel@redhat.com>
2015-07-07virtio-gpu: update console device property.Gerd Hoffmann1-0/+7
Update the device link of the QemuConsole, so it points to the virtio-gpu-pci or virtio-vga device instead of virtio-gpu-device. This is needed because we want to find the device by id, for example for input routing, and the id specified on the command line is attached to the pci proxy, not the virtio device.

2015-06-12virtio-vga: add virtio gpu device with vga compatibilityGerd Hoffmann1-0/+175
This patch adds a virtio-vga device. It is simliar to virtio-gpu-pci, but it also adds in vga compatibility, so guests without native virtio-gpu support can drive the device in vga mode. It is compatible with stdvga. Written by Dave Airlie and Gerd Hoffmann. Signed-off-by: Dave Airlie <airlied@redhat.com> Signed-off-by: Gerd Hoffmann <kraxel@redhat.com>
