Kernen er tilg\u00e6ngelig for x86_64- og ARM64 (aarch64) arkitekturer. Kildeteksten til kernen, inklusive opdelinger i separate patches, er offentliggjort i Oracle's offentlige Git-repository.        <\/p>\n<p>Unbreakable Enterprise Kernel 8-grenen er baseret p\u00e5 Linux-kernen 6.12, som er suppleret med nye funktioner, optimeringer og fejlrettelser, samt testet for kompatibilitet med de fleste applikationer, der k\u00f8rer p\u00e5 RHEL, og optimeret til at arbejde med Oracle's industrielle software og hardware. Installations- og src-pakker med UEK 8.2-kernen er forberedt til grene af Oracle Linux 9 og Oracle Linux 10 (der er ingen hindringer for at bruge denne kerne i tilsvarende versioner af RHEL, CentOS, Alma Linux og Rocky Linux).     <\/p>\n<p>Blandt \u00e6ndringerne i UEK 8.2-kernen:  <\/p>\n<ul>\n<li class=\"l\"> For hypervisoren og g\u00e6stesystemerne er der implementeret mulighed for at bruge mekanismerne Intel TDX (Trusted Domain Extensions) og AMD SEV-SNP (Secure Encrypted Virtualization-Secure Nested Paging) for at beskytte g\u00e6stesystemer mod indgreb og analyse fra administratoren af v\u00e6rtssystemet samt mod fysiske angreb p\u00e5 hardwaren. Beskyttelsen opn\u00e5s ved hukommelseskryptering. <a class=\"wpil_keyword_link\" href=\"https:\/\/prohoster.info\/da\/vps\/\" title=\"virtual machines\" data-wpil-keyword-link=\"linked\">virtual machines<\/a>.\n<li class=\"l\"> Muligheden for at gendanne XFS-filsystemet i online-tilstand ved hj\u00e6lp af v\u00e6rkt\u00f8jet xfs_scrub er blevet tilf\u00f8jet, uden at det er n\u00f8dvendigt at afmontere partitionen og uden at stoppe arbejdet med filsystemet.\n<li class=\"l\"> Der er blevet tilf\u00f8jet support til letv\u00e6gts overv\u00e5gnings sider i hukommelsen (guard page), hvis adgang medf\u00f8rer en undtagelse og en n\u00f8dstop af processen (SIGSEGV). I forhold til mapping i PROT_NONE-tilstand g\u00f8r overv\u00e5gnings sider det muligt at blokere udf\u00f8relsen af kode uden for det tildelte hukommelsesomr\u00e5de mere effektivt, da deres oprettelse ikke kr\u00e6ver tildeling af et nyt virtuelt hukommelsesomr\u00e5de.\n<li class=\"l\"> Muligheden for profilering af hukommelsesallokerings- og frig\u00f8relsesoperationer i systemet er blevet implementeret, hvilket g\u00f8r det muligt at indsamle statistik om hukommelsesallokering og st\u00f8rrelsen af den anvendte hukommelse samt identificere hukommelsesl\u00e6kager. For at aktivere profilering foresl\u00e5s sysctl-parametret &#171;sysctl.vm.mem_profiling=1&#187;, og adgangen til informationen foretages via \"\/proc\/allocinfo.\"\n<li class=\"l\"> Driverne til enhederne AMD HSMP, Intel Ethernet Connection XL710, Intel Data Streaming Accelerator, Intel 10 Gigabit PCI Express, Broadcom Emulex Fibre Channel HBA, NVIDIA ConnectX er blevet opdateret.    <\/ul>\n<p>Der skal ogs\u00e5 n\u00e6vnes opdateringen af UEK-next (Next Unbreakable Enterprise Kernel), som nu bruger Linux-kernen version 6.19. UEK-next pr\u00e6senteres som en kontinuerligt opdateret mulighed for udviklere, der giver adgang til de mest friske forbedringer fra hovedlinjen af kernen, samtidig med at adgangen til de specifikke udvidede funktioner ved UEK opretholdes. UEK-next-kernen dannes ved at l\u00e6gge rettelser og forbedringer fra UEK p\u00e5 mainline-kernen af Linux. Efter et stykke tid vil et af UEK-next-kernene blive tildelt en langvarig supportcyklus (LTS), og denne kerne vil blive brugt som grundlag for at danne UEK 9.<br \/>\n<br \/>Kilde: <a rel=\"nofollow\"
