O n\u00facleo est\u00e1 dispon\u00edvel para as arquiteturas x86_64 e ARM64 (aarch64). O c\u00f3digo-fonte do n\u00facleo, incluindo a divis\u00e3o em patches separados, foi publicado em um reposit\u00f3rio Git p\u00fablico da Oracle.        <\/p>\n<p>A ramifica\u00e7\u00e3o do Unbreakable Enterprise Kernel 8 \u00e9 baseada no n\u00facleo Linux 6.12, que foi complementado com novos recursos, otimiza\u00e7\u00f5es e corre\u00e7\u00f5es, al\u00e9m de ter sido testado quanto \u00e0 compatibilidade com a maioria dos aplicativos que funcionam no RHEL, sendo otimizado para funcionar com software e hardware industriais da Oracle.

Em compara\u00e7\u00e3o com o mapeamento no modo PROT_NONE, as p\u00e1ginas de guarda permitem bloquear de forma mais eficaz a execu\u00e7\u00e3o de c\u00f3digo fora da \u00e1rea de mem\u00f3ria alocada, uma vez que sua cria\u00e7\u00e3o n\u00e3o requer aloca\u00e7\u00e3o de uma nova \u00e1rea de mem\u00f3ria virtual.\n<li class=\"l\"> Foi implementada a possibilidade de perfilamento das opera\u00e7\u00f5es de aloca\u00e7\u00e3o e libera\u00e7\u00e3o de mem\u00f3ria no sistema, coletando estat\u00edsticas sobre a aloca\u00e7\u00e3o de mem\u00f3ria e o tamanho da mem\u00f3ria utilizada, e identificando vazamentos de mem\u00f3ria. Para ativar o perfilamento, foi proposto o par\u00e2metro sysctl \"sysctl.vm.mem_profiling=1\", e o acesso \u00e0s informa\u00e7\u00f5es \u00e9 feito atrav\u00e9s de \/proc\/allocinfo.\n<li class=\"l\"> Os drivers para dispositivos AMD HSMP, Intel Ethernet Connection XL710, Intel Data Streaming Accelerator, Intel 10 Gigabit PCI Express, Broadcom Emulex Fibre Channel HBA e NVIDIA ConnectX foram atualizados.    <\/ul>\n<p>Al\u00e9m disso, pode ser destacado o lan\u00e7amento da branch UEK-next (Next Unbreakable Enterprise Kernel), que foi atualizada para usar a vers\u00e3o do kernel Linux 6.19. O UEK-next \u00e9 apresentado como uma op\u00e7\u00e3o continuamente atualizada para desenvolvedores, permitindo o acesso \u00e0s melhorias mais recentes da branch principal do kernel, mantendo ao mesmo tempo acesso a recursos avan\u00e7ados espec\u00edficos do kernel UEK. O kernel UEK-next \u00e9 formado pela aplica\u00e7\u00e3o de corre\u00e7\u00f5es e melhorias ao kernel mainline do Linux, desenvolvidas para o kernel UEK. Em algum momento, um dos kernels UEK-next ter\u00e1 um ciclo de suporte de longo prazo (LTS) garantido, e esse kernel ser\u00e1 usado como base para a forma\u00e7\u00e3o da branch UEK 9.<br \/>\n<br
