Onjiniyela be-Raspberry Pi bamemezele ukunikezwa isitifiketi komshayeli wezithombe ze-v3dv yinhlangano ye-Khronos, ephumelele ngempumelelo izivivinyo ezingaphezu kwezinkulungwane eziyi-100 kusukela kusethi ye-CTS (Kronos Conformance Test Suite) futhi etholakala ihambisana ngokugcwele nokucaciswa kwe-Vulkan 1.1.
Umshayeli ugunyazwe kusetshenziswa i-chip ye-Broadcom BCM2711 esetshenziswe kumabhodi we-Raspberry Pi 4, Raspberry Pi 400 kanye ne-Compute Module 4. Ukuhlolwa kwenziwa ebhodini le-Raspberry Pi 4 ngokusatshalaliswa kwe-Raspberry Pi OS okusekelwe ku-Linux kernel 5.10.63, Mesa. 21.3.0 kanye namaseva we-X. Ukuthola isitifiketi kukuvumela ukuthi umemezele ngokusemthethweni ukuhambisana namazinga wezithombe futhi usebenzise izimpawu zokuthengisa ezihlotshaniswayo ze-Khronos.
Ngokungeziwe ku-Vulkan 1.1, umshayeli we-v3dv uphinde wethula ukwesekwa kwamashadi ejometri kanye nezandiso ze-Vulkan ezingacacisiwe. Ukusekelwa okuthuthukisiwe kwe-3D debugger RenderDoc kanye ne-tracer GFXReconstruct. Ngaphezu kwalokho, abashayeli be-OpenGL kanye ne-Vulkan baye bakwandisa kakhulu ukusebenza kwekhodi ekhiqizwe i-shader compiler, enomthelela omuhle ngesivinini sezinhlelo ezisebenzisa ama-shader ngenkuthalo, njengemidlalo esekelwe ku-Unreal Engine 4. Igrafu engezansi ibonisa ukukhuphuka kokusebenza kweminye imidlalo njengephesenti:
Zonke izinguquko eziphawuliwe kumshayeli we-v3dv sezivele zamukelwe kuphrojekthi enkulu ye-Mesa futhi zizotholakala maduze ekusabalaliseni i-Raspberry Pi OS. Umshayeli we-v3dv unomkhawulo ekusekeleni i-VideoCore VI i-accelerator, esetshenziswa kuqala ngemodeli ye-Raspberry Pi 4. Emabhodini amadala, umshayeli we-RPi-VK-Driver uthuthukiswa ngokuhlukana, osebenzisa kuphela i-subset ye-Vulkan API, kusukela amandla e-VideoCore GPU ahlinzekwe ngamabhodi ngaphambi kokuthi i-Raspberry Pi 4 ibe nomkhawulo. akwanele ukusebenzisa ngokugcwele i-Vulkan API.
