La empresa Collabora ha presentado el controlador Venus, que ofrece una GPU virtual (VirtIO-GPU) implementada sobre la API gr\u00e1fica Vulkan. Venus es similar al controlador VirGL, que estaba disponible previamente y se basaba en la API OpenGL, y tambi\u00e9n permite proporcionar a cada sistema hu\u00e9sped una GPU virtual para el renderizado 3D, sin abrir acceso directo exclusivo al GPU f\u00edsico. El c\u00f3digo de Venus ya est\u00e1 incluido en Mesa y se entrega a partir de la versi\u00f3n 21.1. <\/p>\n

El controlador Venus define el protocolo Virtio-GPU para la serializaci\u00f3n de comandos de la API gr\u00e1fica Vulkan. Para el dibujo en los sistemas hu\u00e9spedes, se utiliza la biblioteca virglrenderer, que asegura la transducci\u00f3n de comandos de los controladores Venus y VirGL a comandos de Vulkan y OpenGL. Para interactuar con el GPU f\u00edsico en el sistema host, se pueden utilizar controladores Vulkan ANV (Intel) o RADV (AMD) incluidos en Mesa. <\/p>\n

La nota incluye una gu\u00eda detallada sobre el uso de Venus en sistemas de virtualizaci\u00f3n basados en QEMU y KVM<\/a>. Para operar del lado del host, se requiere un n\u00facleo de Linux 5.16-rc con soporte para \/dev\/udmabuf (compilaci\u00f3n con la opci\u00f3n CONFIG_UDMABUF), as\u00ed como ramas separadas de virglrenderer (rama res-sharing) y QEMU (rama venus-dev). Del lado del sistema invitado, es necesario tener un n\u00facleo de Linux 5.16-rc y el paquete Mesa 21.1+, compilado con la opci\u00f3n \u00ab-Dvulkan-drivers=virtio-experimental\u00bb.
