Apresentado<\/a><\/noindex> a primeira vers\u00e3o est\u00e1vel do driver gr\u00e1fico aberto RPi-VK-Driver 1.0<\/a><\/noindex>, implementando suporte para a API gr\u00e1fica Vulkan em placas antigas Raspberry Pi, equipadas com GPU Broadcom Videocore IV. O driver \u00e9 compat\u00edvel com todos os modelos de placas Raspberry Pi lan\u00e7ados antes do Raspberry Pi 4, \u2014 do 'Zero' e '1 Model A' at\u00e9 '3 Model B+' e 'Compute Module 3+'. O driver foi desenvolvido por Martin Thomas (Martin Thomas<\/a><\/noindex>), engenheiro da NVIDIA, entretanto, o desenvolvimento foi realizado como um projeto pessoal, n\u00e3o relacionado \u00e0 NVIDIA (o driver foi desenvolvido nos \u00faltimos dois anos em tempo livre). O c\u00f3digo \u00e9 distribu\u00eddo<\/a><\/noindex> sob a licen\u00e7a MIT.<\/p>\n

Como as capacidades da GPU VideoCore IV, que equipam os modelos antigos da Raspberry Pi, n\u00e3o s\u00e3o suficientes para a plena implementa\u00e7\u00e3o do Vulkan, o driver implementa apenas um subconjunto da API Vulkan, que n\u00e3o abrange todo o padr\u00e3o, mas tenta segui-lo na medida em que o hardware permite. No entanto, a funcionalidade dispon\u00edvel \u00e9 suficiente para muitos aplicativos e jogos, e o desempenho supera significativamente os drivers OpenGL, devido a uma gest\u00e3o de mem\u00f3ria mais eficaz, processamento de comandos de GPU em m\u00faltiplas threads e controle direto das opera\u00e7\u00f5es da GPU. O driver tamb\u00e9m suporta funcionalidades como MSAA (anti-aliasing multiexemplo), shaders de baixo n\u00edvel e contadores de desempenho. Entre as limita\u00e7\u00f5es, destaca-se a aus\u00eancia de suporte a shaders GLSL, que ainda n\u00e3o est\u00e3o dispon\u00edveis nesta fase de desenvolvimento.<\/p>\n

O mesmo autor foi publicado<\/a><\/noindex> port do jogo Quake 3 para Raspberry Pi, servindo como uma demonstra\u00e7\u00e3o das capacidades do novo driver. O jogo \u00e9 baseado no motor ioQuake3, que teve um backend de renderiza\u00e7\u00e3o modular baseado em Vulkan, inicialmente desenvolvido pelo projeto Quake III Arena Kenny Edition<\/a><\/noindex>. Com o novo driver, conseguimos atingir<\/a><\/noindex> mais de 100 quadros por segundo (FPS) na placa Raspberry Pi 3B+ com uma resolu\u00e7\u00e3o de sa\u00edda de 720p.<\/p>\n

Lembramos que a organiza\u00e7\u00e3o Raspberry Pi Foundation, em conjunto com a empresa Igalia est\u00e1<\/a><\/noindex> desenvolvendo seu pr\u00f3prio driver Vulkan, que est\u00e1 em est\u00e1gio inicial de desenvolvimento e estar\u00e1 pronto para executar alguns aplicativos reais na segunda metade de 2020. O referido driver est\u00e1 limitado ao suporte do acelerador gr\u00e1fico VideoCore VI, utilizado a partir do modelo Raspberry Pi 4, e n\u00e3o suporta placas antigas. Em compara\u00e7\u00e3o com OpenGL, o uso de Vulkan permite um aumento de desempenho<\/a><\/noindex> para aplicativos e jogos gr\u00e1ficos.<\/p>\n
