Add new virtio-gpu devices with a "vhost-user" property. Tthe associated vhost-user backend is used to handle the virtio rings and provide rendering results thanks to the vhost-user-gpu protocol. Example usage: -object vhost-user-backend,id=vug,cmd="./vhost-user-gpu" -device vhost-user-vga,vhost-user=vug Signed-off-by: Marc-André Lureau <marcandre.lureau@redhat.com> --- hw/virtio/virtio-pci.h | 1 + include/hw/virtio/virtio-gpu.h | 13 + hw/display/vhost-user-gpu-pci.c | 51 ++++ hw/display/vhost-user-gpu.c | 524 ++++++++++++++++++++++++++++++++ hw/display/vhost-user-vga.c | 52 ++++ vl.c | 1 + hw/display/Makefile.objs | 3 + 7 files changed, 645 insertions(+) create mode 100644 hw/display/vhost-user-gpu-pci.c create mode 100644 hw/display/vhost-user-gpu.c create mode 100644 hw/display/vhost-user-vga.c
