L'azienda Collabora ha presentato il driver Venus, che offre una GPU virtuale (VirtIO-GPU) basata sull'API grafica Vulkan. Venus ricorda il precedente driver VirGL, sviluppato sulla base dell'API OpenGL, e consente di fornire a ciascun sistema guest una GPU virtuale per il rendering 3D, senza l'accesso diretto esclusivo alla GPU fisica. Il codice di Venus \u00e8 gi\u00e0 incluso in Mesa ed \u00e8 disponibile a partire dalla versione 21.1. <\/p>\n

Il driver Venus definisce il protocollo Virtio-GPU per la serializzazione dei comandi dell'API grafica Vulkan. Per il rendering sui sistemi guest viene utilizzata la libreria virglrenderer, che traduce i comandi dai driver Venus e VirGL in comandi Vulkan e OpenGL. Per interagire con la GPU fisica lato host possono essere utilizzati i driver Vulkan ANV (Intel) o RADV (AMD) inclusi in Mesa. <\/p>\n
