A iniciativa para implementar o suporte ao chip Apple M1 no Linux, promovida pelos projetos Asahi Linux e Corellium, atingiu um n\u00edvel em que \u00e9 poss\u00edvel iniciar a \u00e1rea de trabalho GNOME em um ambiente Linux executado em um sistema com o chip Apple M1. A sa\u00edda de v\u00eddeo \u00e9 organizada atrav\u00e9s de framebuffer, e o suporte a OpenGL \u00e9 garantido por meio do rasterizador de software LLVMPipe. O pr\u00f3ximo passo ser\u00e1 envolver o coprocessador de v\u00eddeo para sa\u00edda com resolu\u00e7\u00e3o de at\u00e9 4K, sendo que a engenharia reversa dos drivers j\u00e1 foi realizada. <\/p>\n

O projeto Asahi conseguiu incluir no n\u00facleo principal do Linux o suporte inicial a componentes SoC M1 que n\u00e3o est\u00e3o relacionados ao GPU. No ambiente Linux demonstrado, al\u00e9m das capacidades do n\u00facleo padr\u00e3o, foram utilizados v\u00e1rios patches adicionais relacionados ao PCIe, driver pinctrl para o barramento interno e driver de exibi\u00e7\u00e3o. Essas adi\u00e7\u00f5es permitiram a sa\u00edda de v\u00eddeo e a funcionalidade de USB e Ethernet. A acelera\u00e7\u00e3o gr\u00e1fica ainda n\u00e3o est\u00e1 em uso. <\/p>\n

\u00c9 interessante notar que, para a engenharia reversa do SoC M1, o projeto Asahi optou por implementar um hipervisor em vez de tentar desassemblar os drivers do macOS, que \u00e9 executado em um n\u00edvel entre o macOS e o chip M1, interceptando e registrando todas as opera\u00e7\u00f5es com o chip de forma transparente. Entre as caracter\u00edsticas do SoC M1 que dificultam a implementa\u00e7\u00e3o do suporte a chips em sistemas operacionais de terceiros, menciona-se a adi\u00e7\u00e3o de um coprocessador ao controlador de v\u00eddeo (DCP). Para esse coprocessador, metade da funcionalidade do driver de v\u00eddeo do macOS foi transferida, que chama fun\u00e7\u00f5es prontas do coprocessador atrav\u00e9s de uma interface RPC especial. <\/p>\n

Os entusiastas j\u00e1 desvendaram desafios suficientes dessa interface RPC para ativar o coprocessador para exibi\u00e7\u00e3o na tela, bem como para controlar o cursor de hardware e realizar opera\u00e7\u00f5es de composi\u00e7\u00e3o e escalonamento. O problema \u00e9 que a interface RPC depende do firmware e muda a cada vers\u00e3o do macOS, portanto, no Asahi Linux est\u00e1 planejada a implementa\u00e7\u00e3o do suporte apenas para vers\u00f5es espec\u00edficas do firmware. A princ\u00edpio, o suporte ser\u00e1 garantido para o firmware fornecido no macOS 12 \"Monterey\". Baixar a vers\u00e3o necess\u00e1ria do firmware n\u00e3o \u00e9 poss\u00edvel, pois o firmware \u00e9 instalado pelo iBoot na fase anterior \u00e0 entrega do controle ao sistema operacional, com verifica\u00e7\u00e3o por assinatura digital.
