La soci\u00e9t\u00e9 VMS Software, qui a rachet\u00e9 il y a cinq ans \u00e0 Hewlett-Packard les droits de poursuivre le d\u00e9veloppement du syst\u00e8me d'exploitation OpenVMS (Virtual Memory System), a publi\u00e9 la version OpenVMS 9.1, remarquable par la mise en \u0153uvre du support de l'architecture x86-64. Le syst\u00e8me d'exploitation OpenVMS est en d\u00e9veloppement depuis 1977, utilis\u00e9 dans des syst\u00e8mes critiques n\u00e9cessitant une fiabilit\u00e9 accrue, et n'\u00e9tait auparavant disponible que pour les architectures VAX, Alpha et Intel Itanium. Notamment, les tentatives de portage d'OpenVMS sur des syst\u00e8mes x86 \u00e0 la fin des ann\u00e9es 1980 n'ont pas abouti en raison de l'arr\u00eat du financement, apr\u00e8s quoi l'auteur du port est pass\u00e9 chez Microsoft et a cr\u00e9\u00e9 Windows NT. <\/p>\n

Le port propos\u00e9 d'OpenVMS pour l'architecture x86-64, en plus de l'installation sur du mat\u00e9riel r\u00e9el, prend en charge l'utilisation dans des machines virtuelles<\/a> KVM, VMware et VirtualBox. Le port est construit \u00e0 partir des m\u00eames codes source d'OpenVMS utilis\u00e9s dans les versions pour les architectures Alpha et Itanium, avec utilisation de la compilation conditionnelle rempla\u00e7ant les fonctionnalit\u00e9s li\u00e9es aux sp\u00e9cificit\u00e9s des architectures mat\u00e9rielles. <\/p>\n

Le code d'OpenVMS est adapt\u00e9 pour \u00eatre compil\u00e9 avec LLVM au lieu du compilateur propri\u00e9taire GEM utilis\u00e9 pour la compilation des ports Alpha et Itanium (un traducteur sp\u00e9cial a \u00e9t\u00e9 \u00e9crit pour refl\u00e9ter GEM IR en LLVM IR, et Clang est adapt\u00e9 pour compiler du code C++ pour OpenVMS). Pour la d\u00e9tection et l'initialisation du mat\u00e9riel, UEFI et ACPI sont utilis\u00e9s, et pour le chargement, un disque RAM est utilis\u00e9 \u00e0 la place du m\u00e9canisme de d\u00e9marrage sp\u00e9cial \u00e0 VMS, sp\u00e9cifique au mat\u00e9riel. Pour \u00e9muler les niveaux de privil\u00e8ge manquants des syst\u00e8mes VAX, Alpha et Itanium, manquants dans les syst\u00e8mes x86-64, un module SWIS (Software Interrupt Services) est int\u00e9gr\u00e9 dans le noyau d'OpenVMS.
