Il est not\u00e9 que Tyr a atteint un niveau compatible avec le fonctionnement de l'environnement de bureau GNOME, du serveur composite Weston et des jeux en plein \u00e9cran tels que SuperTuxKart.

Cependant, le pilote n'est pas encore pr\u00eat pour une utilisation permanente par les utilisateurs ordinaires et est consid\u00e9r\u00e9 comme un prototype exp\u00e9rimental pour tester les abstractions pour le d\u00e9veloppement de pilotes en langage Rust.                <\/p>\n<p>Pour cr\u00e9er ce nouveau pilote, des composants du pilote abstrait rust_platform_driver et du pilote Nova, d\u00e9velopp\u00e9 pour les GPU NVIDIA, \u00e9crit en Rust et ajout\u00e9 dans le noyau Linux 6.16, ont \u00e9t\u00e9 utilis\u00e9s. La fonctionnalit\u00e9 pour interagir avec le GPU Mali a \u00e9t\u00e9 port\u00e9e depuis le pilote DRM existant Panthor (Direct Rendering Manager), \u00e9crit en langage C.

Dans les GPU avec interface CSF, au lieu d'un mod\u00e8le bas\u00e9 sur l'envoi d'une cha\u00eene de travaux, un mod\u00e8le bas\u00e9 sur un flux de commandes avec planification de la file d'attente des flux de commandes du c\u00f4t\u00e9 du firmware est appliqu\u00e9. Pour organiser le travail du planificateur, un microcontr\u00f4leur Cortex-M7 distinct est int\u00e9gr\u00e9 dans le GPU, et un bloc sp\u00e9cial d'ex\u00e9cution de commandes (Command Execution Unit) est pr\u00e9vu pour l'ex\u00e9cution des instructions CSF.<br \/>\n<br \/>Source : <a content=\"nofollow\" rel=\"nofollow\"
