Os desenvolvedores da empresa Red Hat anunciaram a implementa\u00e7\u00e3o do suporte inicial para a arquitetura RISC-V no reposit\u00f3rio CentOS Stream 10, que serve de base para o desenvolvimento do Red Hat Enterprise Linux 10. Antes disso, pacotes eram lan\u00e7ados para as arquiteturas x86_64 (x86_64_v3 no RHEL 10), Aarch64, ppc64le (POWER9) e s390x (IBM z14). A Red Hat tamb\u00e9m apresentou vers\u00f5es experimentais do RHEL 10 para sistemas RISC-V, desenvolvidas em colabora\u00e7\u00e3o com a SiFive. <\/p>\n
Atualmente, a maior parte dos patches que resolvem problemas de constru\u00e7\u00e3o e funcionamento de v\u00e1rios pacotes em sistemas riscv64 j\u00e1 est\u00e1 integrada ao reposit\u00f3rio git do CentOS Stream. Alguns patches ainda n\u00e3o foram transferidos para o reposit\u00f3rio principal e permanecem em ramifica\u00e7\u00f5es git separadas, que planejam ser publicadas em 1\u00ba de julho, juntamente com as vers\u00f5es de inicializa\u00e7\u00e3o prontas para funcionar nas placas SiFive HiFive Premier P550. Ap\u00f3s a publica\u00e7\u00e3o das vers\u00f5es na infraestrutura de constru\u00e7\u00e3o em hardware RISC-V, ser\u00e1 iniciado um novo servidor<\/a> Koji e o trabalho continuar\u00e1 para transferir as corre\u00e7\u00f5es criadas para os projetos principais (upstream). <\/p>\n O projeto Rocky Linux, que visa criar uma vers\u00e3o livre do RHEL capaz de substituir o cl\u00e1ssico CentOS, avan\u00e7ou e anunciou o suporte oficial para sistemas RISC-V (riscv64gc) no Rocky Linux 10. O Rocky Linux 10 suportar\u00e1 placas StarFive VisionFive 2 (VF2) e SiFive HiFive Premier P550, al\u00e9m da execu\u00e7\u00e3o emulador QEMU, similar \u00e0s compila\u00e7\u00f5es RISC-V do projeto Fedora. Est\u00e1 sendo considerada a implementa\u00e7\u00e3o do suporte para placas Milk-V e Banana Pi. <\/p>\n A arquitetura RISC-V obteve o status de suporte alternativo e, ao contr\u00e1rio das arquiteturas prim\u00e1rias (x86_64, Aarch64, ppc64le e s390x), n\u00e3o bloquear\u00e1 o lan\u00e7amento de vers\u00f5es para outras arquiteturas. A presen\u00e7a de problemas espec\u00edficos do RISC-V nos pacotes n\u00e3o impedir\u00e1 a publica\u00e7\u00e3o das vers\u00f5es desses pacotes para outras arquiteturas. <\/p>\n Ao trabalhar na placa VisionFive 2 e no QEMU, ser\u00e1 utilizado o kernel padr\u00e3o do RHEL 10, enquanto nas placas da s\u00e9rie SiFive HiFive Premier P550, um kernel separado do fabricante do hardware ser\u00e1 utilizado. O desenvolvimento da vers\u00e3o est\u00e1 sendo feito em colabora\u00e7\u00e3o com o projeto Fedora. O tempo de lan\u00e7amento do Rocky Linux 10 ainda n\u00e3o foi comunicado. <\/p>\n Al\u00e9m disso, pode-se destacar a iniciativa do projeto Alma Linux de criar uma variante do reposit\u00f3rio EPEL 10 (Extra Packages for Enterprise Linux) para a arquitetura x86-64-v2. Ao contr\u00e1rio da distribui\u00e7\u00e3o RHEL 10, que fornece pacotes otimizados para a microarquitetura x86-64-v3, a distribui\u00e7\u00e3o Alma Linux forma compila\u00e7\u00f5es separadas para a microarquitetura x86-64-v2, que s\u00e3o acompanhadas das compila\u00e7\u00f5es b\u00e1sicas x86-64-v3. A partir de agora, as compila\u00e7\u00f5es para x86-64-v2 no Alma Linux n\u00e3o abranger\u00e3o apenas o reposit\u00f3rio principal, mas tamb\u00e9m o reposit\u00f3rio EPEL. Em compara\u00e7\u00e3o com x86-64-v2, o suporte para x86-64-v3 abrange as extens\u00f5es de CPU AVX, AVX2, BMI2, FMA, LZCNT, MOVBE e SXSAVE. O suporte para x86-64-v2 permite manter a compatibilidade com CPUs anteriores ao Intel Haswell e AMD Excavator, projetadas antes de 2013. \u0420\u0430\u0437\u0440\u0430\u0431\u043e\u0442\u0447\u0438\u043a\u0438 \u0438\u0437 \u043a\u043e\u043c\u043f\u0430\u043d\u0438\u0438 Red Hat \u043e\u0431\u044a\u044f\u0432\u0438\u043b\u0438 \u043e \u0440\u0435\u0430\u043b\u0438\u0437\u0430\u0446\u0438\u0438 \u043d\u0430\u0447\u0430\u043b\u044c\u043d\u043e\u0439 \u043f\u043e\u0434\u0434\u0435\u0440\u0436\u043a\u0438 \u0430\u0440\u0445\u0438\u0442\u0435\u043a\u0442\u0443\u0440\u044b RISC-V \u0432 \u0440\u0435\u043f\u043e\u0437\u0438\u0442\u043e\u0440\u0438\u0438 CentOS Stream 10, \u0432\u044b\u0441\u0442\u0443\u043f\u0430\u044e\u0449\u0435\u043c \u043e\u0441\u043d\u043e\u0432\u043e\u0439 \u0434\u043b\u044f \u0440\u0430\u0437\u0440\u0430\u0431\u043e\u0442\u043a\u0438 Red Hat Enterprise Linux 10. \u0414\u043e \u044d\u0442\u043e\u0433\u043e \u043f\u0430\u043a\u0435\u0442\u044b \u0432\u044b\u043f\u0443\u0441\u043a\u0430\u043b\u0438\u0441\u044c \u0434\u043b\u044f \u0430\u0440\u0445\u0438\u0442\u0435\u043a\u0442\u0443\u0440 x86_64 (x86_64_v3 \u0432 RHEL 10), Aarch64, ppc64le (POWER9) \u0438 s390x (IBM z14).
