De ontwikkelaars van Raspberry Pi hebben aangekondigd dat de grafische driver v3dv is gecertificeerd door de Khronos organisatie, die met succes meer dan 100.000 tests uit de CTS (Kronos Conformance Test Suite) heeft doorstaan en volledig compatibel is bevonden met de Vulkan 1.1 specificatie. <\/p>\n

De driver is gecertificeerd bij gebruik van de Broadcom BCM2711 chip, die wordt toegepast in de Raspberry Pi 4, Raspberry Pi 400 en Compute Module 4. De test werd uitgevoerd op de Raspberry Pi 4 met de Raspberry Pi OS-distributie op basis van Linux-kernel 5.10.63, Mesa 21.3.0 en de X-server. Het verkrijgen van de certificering maakt het mogelijk om officieel te claimen dat het compatibel is met grafische standaarden en om bijbehorende handelsmerken van Khronos te gebruiken. <\/p>\n

Naast Vulkan 1.1 ondersteunt de v3dv driver ook geometrische shaders en extensies die niet in de Vulkan specificatie zijn opgenomen. De ondersteuning voor de 3D-debugger RenderDoc en de tracer GFXReconstruct is verbeterd. Bovendien is de prestaties van de gegenereerde code door de shader compiler in de OpenGL en Vulkan drivers aanzienlijk verhoogd, wat de snelheid van programma's die intensief gebruikmaken van shaders, zoals games die draaien op de Unreal Engine 4, ten goede komt. Hieronder is de prestatieverbetering van enkele games in procenten weergegeven:

\"De<\/center> <\/p>\n

Alle genoemde wijzigingen in de v3dv driver zijn al opgenomen in de hoofdprojecten van Mesa en zullen binnenkort beschikbaar zijn in de Raspberry Pi OS distributie. De v3dv driver ondersteunt alleen de VideoCore VI grafische accelerator, die wordt toegepast sinds het Raspberry Pi 4 model. Voor oudere borden wordt de RPi-VK-Driver apart ontwikkeld, die slechts een subset van de Vulkan API implementeert, omdat de mogelijkheden van de VideoCore GPU, die in de borden v\u00f3\u00f3r de Raspberry Pi 4 werden geleverd, niet voldoende zijn voor een volledige implementatie van de Vulkan API.
