La soci\u00e9t\u00e9 Collabora a pr\u00e9sent\u00e9 le pilote Venus, qui propose un GPU virtuel (VirtIO-GPU) bas\u00e9 sur l'API graphique Vulkan. Venus rappelle l'ancien pilote VirGL, qui \u00e9tait bas\u00e9 sur l'API OpenGL, et permet \u00e9galement de fournir \u00e0 chaque syst\u00e8me invit\u00e9 un GPU virtuel pour le rendu 3D, sans donner un acc\u00e8s direct exclusif au GPU physique. Le code de Venus est d\u00e9j\u00e0 int\u00e9gr\u00e9 dans Mesa et est disponible \u00e0 partir de la version 21.1. <\/p>\n

Le pilote Venus d\u00e9finit le protocole Virtio-GPU pour la s\u00e9rialisation des commandes de l'API graphique Vulkan. Pour le rendu sur les syst\u00e8mes invit\u00e9s, la biblioth\u00e8que virglrenderer est utilis\u00e9e, assurant la traduction des commandes des pilotes Venus et VirGL en commandes Vulkan et OpenGL. Pour interagir avec le GPU physique du syst\u00e8me h\u00f4te, les pilotes Vulkan ANV (Intel) ou RADV (AMD) de Mesa peuvent \u00eatre utilis\u00e9s. <\/p>\n

Cet article fournit un guide d\u00e9taill\u00e9 sur l'utilisation de Venus dans les syst\u00e8mes de virtualisation bas\u00e9s sur QEMU et KVM<\/a>. Pour fonctionner c\u00f4t\u00e9 h\u00f4te, un noyau Linux 5.16-rc avec le support de \/dev\/udmabuf (compilation avec l'option CONFIG_UDMABUF) est requis, ainsi que des branches distinctes de virglrenderer (branche res-sharing) et de QEMU (branche venus-dev). C\u00f4t\u00e9 syst\u00e8me invit\u00e9, il est n\u00e9cessaire d'avoir un noyau Linux 5.16-rc et le package Mesa 21.1+, compil\u00e9 avec l'option \u00ab -Dvulkan-drivers=virtio-experimental \u00bb.
