qxl is a paravirtual graphics card. The qxl device is the bridge between the guest and the spice server (aka libspice-server). The spice server will send the rendering commands to the spice client, which will actually render them. The spice server is also able to render locally, which is done in case the guest wants read something from video memory. Local rendering is also used to support display over vnc and sdl. qxl is activated using "-vga qxl". qxl supports multihead, additional cards can be added via '-device qxl". [ v2: add copyright to files ] [ v2: use qemu-common.h for standard includes ] [ v2: create separate qxl-vga device for primary ] Signed-off-by: Gerd Hoffmann <kraxel@redhat.com>
