Hector Martin prop\u00f4s incluir no kernel do Linux o primeiro conjunto de patches preparados pelo projeto Asahi Linux, que trabalha na adapta\u00e7\u00e3o do Linux para computadores Mac com chip ARM Apple M1. Esses patches j\u00e1 foram aprovados pelo mantenedor da branch Linux SoC e aceitos na base de c\u00f3digo Linux-next, a partir da qual \u00e9 formada a funcionalidade do kernel 5.13. Tecnicamente, Linus Torvalds pode bloquear a entrega das mudan\u00e7as propostas, mas essa possibilidade \u00e9 considerada improv\u00e1vel. <\/p>\n
Os patches incluem suporte para componentes SoC M1 n\u00e3o relacionados ao GPU, como controlador de interrup\u00e7\u00f5es, temporizador, UART, SMP, fun\u00e7\u00f5es para organiza\u00e7\u00e3o de entrada\/sa\u00edda e MMIO. A engenharia reversa do GPU ainda n\u00e3o foi conclu\u00edda; para a sa\u00edda, os patches oferecem suporte a framebuffer e console atrav\u00e9s do port serial. \u00c9 declarada a compatibilidade com o computador Apple Mac mini, que \u00e9 usado como plataforma de refer\u00eancia no projeto Asahi Linux (h\u00e1 um guia detalhado de instala\u00e7\u00e3o). <\/p>\n
Um adaptador de hardware aberto est\u00e1 sendo desenvolvido, reconhecido por simplificar a conex\u00e3o ao console via port serial e a realiza\u00e7\u00e3o de depura\u00e7\u00e3o. No estado atual, devido ao uso pela Apple de comandos USB-PD n\u00e3o padronizados em seu hardware, a forma mais simples de acessar o console \u00e9 conectar a outro computador baseado no chip Apple M1 utilizando um cabo USB C. Uma forma mais complexa envolve criar uma interface baseada em um microcontrolador Arduino, chip FUSB30 e adaptador UART-TTL. <\/p>\n
O projeto tamb\u00e9m preparou o carregador m1n1, que possibilita carregar o n\u00facleo Linux e um ambiente m\u00ednimo de sistema em computadores Mac com CPU Apple M1. A Apple permite que, em computadores com CPU M1, sejam carregados n\u00facleos n\u00e3o assinados digitalmente sem a necessidade de usar jailbreak. Essa caracter\u00edstica permite que os desenvolvedores experimentem novos n\u00facleos XNU, mas ao tentar carregar outros sistemas, surgem dificuldades, j\u00e1 que a Apple utiliza seu pr\u00f3prio protocolo de inicializa\u00e7\u00e3o e um formato diferente de Device Tree. O carregador m1n1, proposto pelo projeto Asahi Linux, atua como uma camada que permite usar o Device Tree padr\u00e3o e o protocolo de inicializa\u00e7\u00e3o utilizado no n\u00facleo Linux para ARM64. Futuramente, no m1n1, pretende-se adicionar a capacidade de invocar U-Boot e GRUB para organizar um processo de inicializa\u00e7\u00e3o t\u00edpico, semelhante ao utilizado em outras plataformas ARM64. \u0413\u0435\u043a\u0442\u043e\u0440 \u041c\u0430\u0440\u0442\u0438\u043d (Hector Martin), \u043f\u0440\u0435\u0434\u043b\u043e\u0436\u0438\u043b
