Esitletud<\/a><\/noindex> esimene stabiilne versioon avatud graafikadriverist RPi-VK-Driver 1.0<\/a><\/noindex>, toetaen graafilise API Vulkani toetuse vanade Raspberry Pi plaatide jaoks, mis on varustatud Broadcom Videocore IV GPU-ga. Draiver sobib k\u00f5igile Raspberry Pi mudelitele, mis on v\u00e4lja antud enne Raspberry Pi 4 ilmumist \u2014 alates 'Zero' ja '1 Model A' kuni '3 Model B+' ja 'Compute Module 3+'. Draiveri arendas Martin Thomas (Martin Thomas<\/a><\/noindex>), NVIDIA insener, siiski arendamine toimus isikliku projektina, mis ei ole seotud NVIDIA-ga (juhtmeid arendati viimased kaks aastat vabal ajal). Kood levitatakse<\/a><\/noindex> MIT litsentsi alusel.<\/p>\n

Kuna GPU VideoCore IV, millega on varustatud vanad Raspberry Pi mudelid, ei paku piisavalt funktsioone Vulkani t\u00e4ielikuks rakendamiseks, sisaldab draiver vaid Vulkan API alamosa, mis ei h\u00f5lma kogu standardit, kuid p\u00fc\u00fcab sellele j\u00e4lgida nii palju kui riistvara v\u00f5imaldab. Siiski on saadaval funktsionaalsus piisav paljude rakenduste ja m\u00e4ngude jaoks ning j\u00f5udlus \u00fcletab oluliselt OpenGL draivereid, t\u00e4nu t\u00f5husamale m\u00e4luhaldusele, mitme l\u00f5ime t\u00f6\u00f6tlemisele GPU komandodele ja otsesele GPU operatsioonide juhtimisele. Draiver toetab ka selliseid funktsioone nagu MSAA (Multisample anti-aliasing), madalama taseme shaderid ja j\u00f5udluse loendurid. Piirangutest m\u00e4rgitakse GLSL shaderite toe puudumine, mis pole praeguses arendusetapis veel saadaval.<\/p>\n

Sama autor avaldati<\/a><\/noindex> Quake 3 m\u00e4ngu port Raspberry Pi jaoks, mis toimib uue draiveri v\u00f5imaluste demonstreerimise n\u00e4idistena. M\u00e4ng p\u00f5hineb ioQuake3 mootoril, kuhu on lisatud modulaarsel Vulkanil p\u00f5hinev renderdamise tagaplaan, mida arendati algselt selle projekti raames.

Uue draiveri kasutamisel m\u00e4ngus \u00f5nnestus saavutada<\/a><\/noindex> \u00fcle 100 kaadri sekundis (FPS) Raspberry Pi 3B+ plaadil, kui v\u00e4ljund oli 720p resolutsiooniga.<\/p>\n

Meenutame, et Raspberry Pi Foundation koos ettev\u00f5tte Igalia-ga juhtib<\/a><\/noindex> arendab oma Vulkan draiverit, mis on arendamise algstaadiumis ja mille jaoks on oodata, et see saab valmis reaalses rakendustes teise poole 2020. aastast. Mainitud draiver toetab ainult VideoCore VI graafika kiirendit, mis on kasutusel alates Raspberry Pi 4 mudelist ja ei toeta vanemaid plaate. Vulkani kasutamine v\u00f5imaldab saavutada j\u00f5udluse t\u00f5usu<\/a><\/noindex> graafilistes rakendustes ja m\u00e4ngudes.<\/p>\n
