O driver \u00e9 escrito em Rust e inclui um conjunto de vinculadores universais sobre a subsistema DRM (Direct Rendering Manager), que podem ser usados para desenvolver outros drivers gr\u00e1ficos em Rust. O conjunto de patches publicado foi oferecido apenas para discuss\u00e3o entre os desenvolvedores do n\u00facleo (RFC), mas pode ser aceito no conjunto principal ap\u00f3s a conclus\u00e3o da revis\u00e3o e corre\u00e7\u00e3o dos problemas identificados.    <\/p>\n<p>Desde dezembro, o driver faz parte do pacote com o n\u00facleo para a distribui\u00e7\u00e3o Asahi Linux e foi testado pelos usu\u00e1rios deste projeto. O driver pode ser utilizado em distribui\u00e7\u00f5es Linux para organizar o funcionamento do ambiente gr\u00e1fico em dispositivos Apple com SoC M1, M1 Pro, M1 Max, M1 Ultra e M2. Ao desenvolver o driver, foi feita uma tentativa n\u00e3o apenas de aumentar a seguran\u00e7a, minimizando erros ao trabalhar com mem\u00f3ria no c\u00f3digo executado pelo CPU, mas tamb\u00e9m de garantir prote\u00e7\u00e3o parcial contra problemas que surgem ao interagir com o firmware. Em particular, o driver fornece certos vinculadores para estruturas n\u00e3o seguras de mem\u00f3ria compartilhada com cadeias de ponteiros complexos, aplicadas no firmware para interagir com o driver.      <\/p>\n<p>O driver proposto \u00e9 usado em conjunto com o driver Mesa asahi, que fornece suporte ao OpenGL no espa\u00e7o do usu\u00e1rio e passa com sucesso nos testes de compatibilidade com OpenGL ES 2, estando quase pronto para suportar OpenGL ES 3.0. Enquanto isso, o driver em n\u00edvel de n\u00facleo est\u00e1 sendo desenvolvido desde o in\u00edcio com a futura compatibilidade com a API Vulkan em mente, e a interface de programa\u00e7\u00e3o para intera\u00e7\u00e3o com o espa\u00e7o do usu\u00e1rio \u00e9 projetada com base no UAPI fornecido pelo novo driver Intel Xe.<br \/>\n<br \/>Fonte: <a content=\"nofollow\" rel=\"nofollow\"
