Deweloperzy Raspberry Pi og\u0142osili certyfikacj\u0119 sterownika graficznego v3dv przez organizacj\u0119 Khronos, kt\u00f3ry pomy\u015blnie przeszed\u0142 ponad 100 tysi\u0119cy test\u00f3w z zestawu CTS (Kronos Conformance Test Suite) i zosta\u0142 uznany za w pe\u0142ni zgodny ze specyfikacj\u0105 Vulkan 1.1. <\/p>\n

Sterownik zosta\u0142 certyfikowany przy u\u017cyciu chipu Broadcom BCM2711, stosowanego w p\u0142ytach Raspberry Pi 4, Raspberry Pi 400 i Compute Module 4. Testy przeprowadzono na p\u0142ycie Raspberry Pi 4 z dystrybucj\u0105 Raspberry Pi OS opart\u0105 na j\u0105drze Linux 5.10.63, Mesa 21.3.0 oraz serwerze X. Uzyskanie certyfikatu pozwala na oficjalne og\u0142aszanie zgodno\u015bci z standardami graficznymi oraz korzystanie z powi\u0105zanych znak\u00f3w towarowych Khronos. <\/p>\n

Opr\u00f3cz Vulkan 1.1, sterownik v3dv wprowadza r\u00f3wnie\u017c wsparcie dla shader\u00f3w geometri i rozszerze\u0144 nieobj\u0119tych specyfikacj\u0105 Vulkan. Ulepszono wsparcie dla debuggera 3D RenderDoc i narz\u0119dzia do \u015bledzenia GFXReconstruct. Co wi\u0119cej, w sterownikach OpenGL i Vulkan znacznie zwi\u0119kszono wydajno\u015b\u0107 kodu generowanego przez kompilator shader\u00f3w, co pozytywnie wp\u0142yn\u0119\u0142o na szybko\u015b\u0107 dzia\u0142ania program\u00f3w intensywnie wykorzystuj\u0105cych shadery, na przyk\u0142ad gier opartych na silniku Unreal Engine 4. Na poni\u017cszym wykresie przedstawiono wzrost wydajno\u015bci niekt\u00f3rych gier w procentach:

Wszystkie wymienione zmiany w sterowniku v3dv zosta\u0142y ju\u017c przyj\u0119te do g\u0142\u00f3wnego projektu Mesa i wkr\u00f3tce b\u0119d\u0105 dost\u0119pne w dystrybucji Raspberry Pi OS. Sterownik v3dv ogranicza si\u0119 do wsparcia dla akceleratora graficznego VideoCore VI, u\u017cywanego od modelu Raspberry Pi 4. Dla starszych p\u0142yt rozwijany jest oddzielny sterownik RPi-VK-Driver, kt\u00f3ry implementuje jedynie podzestaw API Vulkan, poniewa\u017c mo\u017cliwo\u015bci GPU VideoCore stosowanego w p\u0142ytach sprzed Raspberry Pi 4 s\u0105 niewystarczaj\u0105ce do pe\u0142nej implementacji API Vulkan.
