Raspberry Pi-udviklerne har annonceret certificeringen af grafisk driver v3dv af Khronos, som har best\u00e5et mere end 100.000 tests fra CTS (Kronos Conformance Test Suite) og anerkendes som fuldt kompatibel med Vulkan 1.1-specifikationen. <\/p>\n

Driveren er certificeret ved brug af Broadcom BCM2711-chippen, anvendt i Raspberry Pi 4, Raspberry Pi 400 og Compute Module 4. Testen blev udf\u00f8rt p\u00e5 Raspberry Pi 4 med Raspberry Pi OS distribueret p\u00e5 basis af Linux-kernen 5.10.63, Mesa 21.3.0 og X-serveren. At modtage certificeringen giver mulighed for officielt at erkl\u00e6re kompatibilitet med grafiske standarder og bruge de tilknyttede varem\u00e6rker fra Khronos. <\/p>\n

Udover Vulkan 1.1 har driveren v3dv ogs\u00e5 implementeret underst\u00f8ttelse af geometriske shaders og udvidelser, der ikke er d\u00e6kket af Vulkan-specifikationen. Underst\u00f8ttelsen af 3D-debuggeren RenderDoc og traceren GFXReconstruct er forbedret. Derudover er ydeevnen af den kode, der genereres af shaderkompilatoren, betydeligt forbedret i b\u00e5de OpenGL- og Vulkan-drivere, hvilket har haft en positiv indvirkning p\u00e5 hastigheden af programmer, der aktivt bruger shaders, som f.eks. spil baseret p\u00e5 Unreal Engine 4. P\u00e5 grafikken nedenfor vises stigningen i ydeevnen for nogle spil i procent:

Alle de n\u00e6vnte \u00e6ndringer i driveren v3dv er allerede blevet accepteret i hovedprojektet Mesa og vil snart v\u00e6re tilg\u00e6ngelige i Raspberry Pi OS-distributionen. Driveren v3dv er begr\u00e6nset til underst\u00f8ttelse af grafikacceleratoren VideoCore VI, som er anvendt siden Raspberry Pi 4-modellen. For \u00e6ldre boards udvikles driveren RPi-VK-Driver separat, som kun implementerer et delm\u00e6ngde af Vulkan-API'en, da GPU VideoCore-funktionerne fra boards f\u00f8r Raspberry Pi 4 ikke er tilstr\u00e6kkelige til en fuld implementering af Vulkan-API'en.
