A Collabora anunciou progresso no desenvolvimento do driver Tyr para o n\u00facleo do Linux, escrito em Rust. O driver \u00e9 projetado para trabalhar com GPUs ARM Mali, que utilizam a tecnologia CSF (Command Stream Frontend), como as Mali G310, G510 e G710. Nota-se que o Tyr alcan\u00e7ou um n\u00edvel adequado para suportar o ambiente de desktop GNOME, o servidor compositor Weston e jogos em tela cheia, como SuperTuxKart. O desempenho do novo driver \u00e9 considerado compar\u00e1vel ao driver Panthor, escrito em C.

O c\u00f3digo do driver Tyr foi incorporado ao n\u00facleo Linux 6.18, cuja vers\u00e3o \u00e9 aguardada no in\u00edcio de dezembro. No entanto, o driver ainda n\u00e3o est\u00e1 pronto para uso regular por usu\u00e1rios comuns e \u00e9 visto como um prot\u00f3tipo experimental para testes de abstra\u00e7\u00f5es para desenvolvimento de drivers em Rust. <\/p>\n

A estrutura para a cria\u00e7\u00e3o do novo driver utilizou componentes do driver abstrato rust_platform_driver e do driver Nova, desenvolvido para GPUs NVIDIA, escrito em Rust e adicionado ao n\u00facleo Linux 6.16. A funcionalidade para intera\u00e7\u00e3o com a GPU Mali foi portiada do DRM-driver existente Panthor (Direct Rendering Manager), escrito em C. A uAPI do driver Tyr \u00e9 id\u00eantica \u00e0 uAPI do driver Panthor, permitindo o uso de componentes de espa\u00e7o do usu\u00e1rio j\u00e1 existentes. <\/p>\n

A tecnologia CSF, utilizada a partir da 10\u00aa gera\u00e7\u00e3o das GPUs Mali, \u00e9 not\u00e1vel pela remo\u00e7\u00e3o de certas fun\u00e7\u00f5es do driver para a firmware e pelo envolvimento de um novo modelo de organiza\u00e7\u00e3o de execu\u00e7\u00e3o de trabalho na GPU. Nas GPUs com interface CSF, em vez do modelo baseado em cadeia de trabalhos, utiliza-se um modelo baseado em fluxo de comandos com agendamento dos fluxos na firmware. Para organizar o trabalho do planejador na GPU, foi incorporado um microcontrolador Cortex-M7 separado, e uma unidade especial de execu\u00e7\u00e3o de comandos (Command Execution Unit) foi projetada para executar as instru\u00e7\u00f5es CSF.
