Le pilote est \u00e9crit en Rust et inclut \u00e9galement un ensemble de liaisons g\u00e9n\u00e9riques pour le sous-syst\u00e8me DRM (Direct Rendering Manager), qui peuvent \u00eatre utilis\u00e9es pour d\u00e9velopper d'autres pilotes graphiques en Rust. Le jeu de correctifs publi\u00e9 est actuellement propos\u00e9 uniquement pour discussion parmi les d\u00e9veloppeurs du noyau (RFC), mais il pourrait \u00eatre int\u00e9gr\u00e9 au noyau principal apr\u00e8s l'ach\u00e8vement de la r\u00e9vision et la correction des d\u00e9fauts identifi\u00e9s.    <\/p>\n<p>Depuis d\u00e9cembre, le pilote fait partie du paquet du noyau pour la distribution Asahi Linux et a \u00e9t\u00e9 test\u00e9 par les utilisateurs de ce projet. Le pilote peut \u00eatre utilis\u00e9 dans les distributions Linux pour faire fonctionner l'interface graphique sur des appareils Apple \u00e9quip\u00e9s de SoC M1, M1 Pro, M1 Max, M1 Ultra et M2. Dans le d\u00e9veloppement du pilote, une tentative a \u00e9t\u00e9 faite non seulement pour am\u00e9liorer la s\u00e9curit\u00e9 en minimisant les erreurs de manipulation de m\u00e9moire dans le code ex\u00e9cut\u00e9 par le CPU, mais aussi pour fournir une protection partielle contre les probl\u00e8mes survenant lors des interactions avec le firmware. En particulier, le pilote offre certaines liaisons pour des structures de m\u00e9moire partag\u00e9e non s\u00e9curis\u00e9es avec des cha\u00eenes de pointeurs complexes utilis\u00e9es dans le firmware pour interagir avec le pilote.      <\/p>\n<p>Le pilote propos\u00e9 est utilis\u00e9 en conjonction avec le pilote Mesa asahi, qui fournit un support OpenGL dans l'espace utilisateurs et r\u00e9ussit les tests de compatibilit\u00e9 avec OpenGL ES 2 et est presque pr\u00eat pour le support d'OpenGL ES 3.0. Parall\u00e8lement, le pilote fonctionnant au niveau du noyau est initialement d\u00e9velopp\u00e9 en tenant compte du futur support de l'API Vulkan, et l'interface logicielle pour interagir avec l'espace utilisateurs est con\u00e7ue en tenant compte de l'UAPI fourni par le nouveau pilote Intel Xe.<br \/>\n<br \/>Source : <a content=\"nofollow\" rel=\"nofollow\"
