AMD vient de mettre en ligne de nouveaux pilotes graphiques pour l’environnement GNU/Linux. Nommés Radeon GPU-PRO, ils proposent la prise en charge de l’API Vulkan.
Ces Radeon GPU-PRO sont en version bêta. Ils prennent en charge plusieurs cartes graphiques à l’architecture GCN dont certaines Radeon R9 series (Radeon R9 380x, Radeon R9 380, Radeon R9 285, Radeon R9 M395X, AMD Radeon R9 Fury X, Radeon R9 Fury ou encore Radeon R9 Nano). Il s’agit de la première version bêta public ce qui explique le ciblage de la distribution Linux Ubuntu seulement. Le paquet contient un script d’installation et le nécessaire en .deb pour une installation sous Ubuntu 14.04.4 LTS alias Trusty Tahr.
AMD souligne
« Ce pilote est conçu comme apporter le support en version bêta des applications Vulkan »
Nous retrouvons ainsi une prise en charge les API
- Vulkan 1.0,
- VDPAU,
- OpenGL 4.5,
- GLX 1.4,
- OpenCL 1.2
A cela s’ajoute des fonctions de réglages d’affichage, de gestion de l’alimentation et le soutien de technologies ADF et du KMS.
Pour le téléchargement, tout se déroule sur la page officielle d’AMD. Vous la trouverez ici : Radeon GPU-Pro Bêta 16.15.1013 pour Ubuntu 14.04.4 LTS. Il n’est pas conseillé pour une utilisation quotidienne d’exploiter cette nouveauté en raison des limitation et problèmes connus. Voici le changelog.

What is Vulkan?
As a complement to OpenGL, descended from AMD’s Mantle, and forged by the industry, Vulkan™ is a powerful low-overhead graphics API that gives software developers deep control over the performance, efficiency, and capabilities of Radeon™ GPUs and multi-core CPUs. More information on Vulkan™ can be found here. More information on the latest Vulkan™-related news for AMD products can be found here.
