*	virtio-gpu: splitting one extended mode guest fb into n-scanouts	Dongwon Kim	2021-11-05	1	-1/+2
\| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \|	When guest is running Linux/X11 with extended multiple displays mode enabled, the guest shares one scanout resource each time containing whole surface rather than sharing individual display output separately. This extended frame is properly splited and rendered on the corresponding scanout surfaces but not in case of blob-resource (zero copy). This code change lets the qemu split this one large surface data into multiple in case of blob-resource as well so that each sub frame then can be blitted properly to each scanout. v2: resizing qemu console in virtio_gpu_update_dmabuf to scanout's width and height v3: updating stub function of virtio_gpu_update_dmabuf to match the type Cc: Gerd Hoffmann <kraxel@redhat.com> Cc: Vivek Kasireddy <vivek.kasireddy@intel.com> Signed-off-by: Dongwon Kim <dongwon.kim@intel.com> Message-Id: <20211104065153.28897-5-dongwon.kim@intel.com> Signed-off-by: Gerd Hoffmann <kraxel@redhat.com>
*	hw/display: Restrict virtio-gpu-udmabuf stubs to !Linux	Philippe Mathieu-Daudé	2021-08-31	1	-0/+27
	When using qemu configured with --enabled-modules, the generic stubs are used instead of the module symbols: qemu-system-x86_64: -device virtio-vga,blob=on: cannot enable blob resources without udmabuf Restrict the stubs to Linux and only link them when CONFIG_VIRTIO_GPU is disabled (only the modularized version is available when it is enabled).
