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 Signed-off-by: Dongwon Kim --- hw/display/virtio-gpu-udmabuf.c | 21 ++++++++++++++------- hw/display/virtio-gpu.c | 4 ++-- include/hw/virtio/virtio-gpu.h | 5 +++-- include/ui/console.h | 4 ++++ stubs/virtio-gpu-udmabuf.c | 3 ++- 5 files changed, 25 insertions(+), 12 deletions(-) diff --git a/hw/display/virtio-gpu-udmabuf.c b/hw/display/virtio-gpu-udmabuf.c index 3c01a415e7..aadf1221ef 100644 --- a/hw/display/virtio-gpu-udmabuf.c +++ b/hw/display/virtio-gpu-udmabuf.c @@ -171,7 +171,8 @@ static VGPUDMABuf *virtio_gpu_create_dmabuf(VirtIOGPU *g, uint32_t scanout_id, struct virtio_gpu_simple_resource *res, - struct virtio_gpu_framebuffer *fb) + struct virtio_gpu_framebuffer *fb, + struct virtio_gpu_rect *r) { VGPUDMABuf *dmabuf;
