F\u00f6retaget VMS Software, som f\u00f6r fem \u00e5r sedan k\u00f6pte r\u00e4ttigheterna fr\u00e5n Hewlett-Packard att forts\u00e4tta utvecklingen av operativsystemet OpenVMS (Virtual Memory System), har publicerat versionen OpenVMS 9.1, som \u00e4r anm\u00e4rkningsv\u00e4rd f\u00f6r implementeringen av st\u00f6d f\u00f6r x86-64-arkitekturen. Operativsystemet OpenVMS har utvecklats sedan 1977 och anv\u00e4nds i system med h\u00f6g tillg\u00e4nglighet som kr\u00e4ver \u00f6kad p\u00e5litlighet, och har tidigare varit tillg\u00e4ngligt endast f\u00f6r arkitekturer som VAX, Alpha och Intel Itanium. Anm\u00e4rkningsv\u00e4rt \u00e4r att f\u00f6rs\u00f6k att portera OpenVMS till x86-system i slutet av 1980-talet misslyckades p\u00e5 grund av att finansieringen avbr\u00f6ts, varp\u00e5 portens skapare gick \u00f6ver till Microsoft och skapade Windows NT. <\/p>\n

Den f\u00f6reslagna porten av OpenVMS f\u00f6r x86-64-arkitekturen st\u00f6der ut\u00f6ver installation p\u00e5 riktig h\u00e5rdvara \u00e4ven anv\u00e4ndning i virtuella maskiner<\/a> KVM, VMware och VirtualBox.

Koden f\u00f6r OpenVMS har anpassats f\u00f6r att byggas med LLVM ist\u00e4llet f\u00f6r den propriet\u00e4ra kompilatorn GEM, som anv\u00e4nds f\u00f6r att bygga portar f\u00f6r Alpha och Itanium (en speciell \u00f6vers\u00e4ttare har skrivits som reflekterar GEM IR till LLVM IR, och Clang har anpassats f\u00f6r att bygga C++-kod f\u00f6r OpenVMS). F\u00f6r att definiera och initiera h\u00e5rdvaran anv\u00e4nds UEFI och ACPI, och f\u00f6r att starta anv\u00e4nds en RAM-disk ist\u00e4llet f\u00f6r den specialanpassade VMS-bootmehanismen som \u00e4r specifik f\u00f6r h\u00e5rdvaran. F\u00f6r att emulera de saknade privilegieniv\u00e5erna f\u00f6r VAX, Alpha och Itanium, som saknas i x86-64-system, anv\u00e4nds en modul f\u00f6r SWIS (Software Interrupt Services) i k\u00e4rnan av OpenVMS.
