Na vers\u00e3o Fedora 42, prevista para o final de abril, foi proposto permitir que os mantenedores incluam nos pacotes op\u00e7\u00f5es adicionais de arquivos execut\u00e1veis, compilados com otimiza\u00e7\u00f5es para as microarquiteturas x86-64-v2, x86-64-v3 e x86-64-v4. \u00c9 ressaltado que o Fedora continua a compilar pacotes para a arquitetura x86-64-v1, enquanto o CentOS utiliza a arquitetura x86-64-v2 durante a compila\u00e7\u00e3o, e o RHEL 10 \u2014 x86-64-v3. Na maioria dos casos, o ganho de desempenho ao compilar para essas arquiteturas n\u00e3o ultrapassa 10%, mas em algumas situa\u00e7\u00f5es resulta em um aumento significativo de desempenho (at\u00e9 120%). A proposta ainda n\u00e3o foi aprovada pelo comit\u00ea FESCo (Fedora Engineering Steering Committee), respons\u00e1vel pela parte t\u00e9cnica do desenvolvimento da distribui\u00e7\u00e3o Fedora. <\/p>\n
No Fedora, j\u00e1 \u00e9 permitido fornecer bibliotecas adicionais, otimizadas para vers\u00f5es avan\u00e7adas da arquitetura x86_64, e essa possibilidade agora est\u00e1 sendo planejada para os arquivos execut\u00e1veis. O carregamento das implementa\u00e7\u00f5es otimizadas das bibliotecas \u00e9 feito pelo vinculador din\u00e2mico (dynamic linker), que verifica a presen\u00e7a de variantes adicionais nos subdiret\u00f3rios glibc-hwcaps, localizados em \u00e1reas do sistema de arquivos que s\u00e3o pesquisadas ao buscar bibliotecas (por exemplo, \/usr\/lib64\/glibc-hwcaps\/x86-64-v2). <\/p>\n
Para os arquivos execut\u00e1veis, \u00e9 proposto o uso de uma camada hwcaps-loader, que escolher\u00e1 e executar\u00e1 a variante do arquivo execut\u00e1vel correspondente \u00e0s capacidades do sistema atual. Para pacotes que fornecem v\u00e1rias variantes de arquivos execut\u00e1veis, recomenda-se expor essa camada atrav\u00e9s de um link simb\u00f3lico. A decis\u00e3o de adicionar arquivos execut\u00e1veis adicionalmente otimizados ser\u00e1 tomada pelos mantenedores, com base nos resultados dos testes de desempenho de pacotes espec\u00edficos. <\/p>\n
As vers\u00f5es x86-64-v* determinam uma forma n\u00e3o oficial de identifica\u00e7\u00e3o de fatias de estado da microarquitetura, abrangendo conjuntos espec\u00edficos de extens\u00f5es: <\/p>\n
Al\u00e9m disso, vale mencionar a proposta de unifica\u00e7\u00e3o da atualiza\u00e7\u00e3o dos carregadores grub e shim nas vers\u00f5es at\u00f4micas e convencionais do Fedora. Em vez de atualizar o conte\u00fado dos diret\u00f3rios \/boot e \/boot\/efi por meio da chamada a um script durante a instala\u00e7\u00e3o do pacote rpm, prop\u00f5e-se usar a ferramenta bootupd para a atualiza\u00e7\u00e3o do carregador, que j\u00e1 \u00e9 aplicada nas vers\u00f5es at\u00f4micas atualiz\u00e1veis do Fedora. Nos pacotes rpm com carregadores, o conte\u00fado deve ser instalado n\u00e3o diretamente nos diret\u00f3rios \/boot e \/boot\/efi, mas em um diret\u00f3rio separado dentro da parti\u00e7\u00e3o \/usr, e em seguida, sincronizar seu conte\u00fado com \/boot e \/boot\/efi. Essa abordagem permitir\u00e1 implementar uma op\u00e7\u00e3o de inicializa\u00e7\u00e3o de backup que pode ser usada para reverter para uma configura\u00e7\u00e3o anterior em caso de problemas ap\u00f3s a atualiza\u00e7\u00e3o do carregador. \u0412 \u0432\u044b\u043f\u0443\u0441\u043a\u0435 Fedora 42, \u043d\u0430\u043c\u0435\u0447\u0435\u043d\u043d\u044b\u0439 \u043d\u0430
