Okusajingijolo ikhompyutha eyodwa yebhodi ukuthi ithole ukuthandwa okuningi futhi isetshenziselwe ukuthuthukiswa kwamaphrojekthi ahlukahlukene, kusuka ekusetshenzisweni kwedivayisi ukwenza i-AI, ukubhekwa kwevidiyo, ukudala i-NAS, phakathi kwabanye. Futhi ngenxa yokuthandwa kwayo okukhulu, umphakathi kade wacela ukuthi le divayisi inayo ukuhambisana neVulkan, okuvela ngisho nakuzo lezo zicelo.
U-Eben Upton (umakhi nomakhi we-Raspberry) wenze isimemezelo kubhulogi le-Raspberry, lapho yembule ukuqala komsebenzi kusishayeli sevidiyo samahhala se i-accelerator yehluzo le-VideoCore VI elisetshenziswe kuma-chips we-Broadcom. Lezi zindaba ziza ngemuva kwesimemezelo sokuthi Ukusajingijolo Pi 4 es iyahambisana ne-OpenGL ES 3.1.
Umshayeli omusha usekelwe kwi-Vulkan graphics API futhi yenzelwe ikakhulukazi ukusetshenziswa namabhodi we-Raspberry Pi 4 namamodeli azokhishwa ngokuzayo. Igalia ihola ukuthuthukiswa kwesilawuli, ngokubambisana neRaspberry Pi Foundation.
Endabeni IVideoCore IV GPU inikezwe ngaphakathi Ukusajingijolo Pi 3, kushiwo ukuthi akwanele ukuqaliswa okugcwele kweVulkan, ngakho-ke ukuhlanganiswa komshayeli kule nguqulo ye-Raspberry Pi kukhishwe ngokuphelele.
IVulkan ibekwe njengegrafu yesizukulwane esilandelayo ne-API yekhompyutha Inikezela ngokufinyelela okuphumelelayo kwepulatifomu kuma-GPU anamuhla.
I-Vulkan API yenzelwe ukwamukela kangcono ama-GPU anamuhla kanye nezinkinga zamakheli amazinga wokusebenza ajwayelekile ku-OpenGL, enikeza abathuthukisi behluzo izindlela ezintsha zokuthola ukusebenza okuhle kakhulu kusuka kwi-hardware.
U-Eben Upton ukhuluma ngokuthunyelwe kwakhe kusuka kubhulogi ukuthi:
IVulkan API yakhelwe ukusebenzisa ngokugcwele i-computing / i-graphware hardware yanamuhla, ekhuluma ngezinkinga ezivamile ku-OpenGL.
Kuze kube manje, kuphela uhlobo lokuqala lwesilawuli esilungiselelwe, olulungele imiboniso elula. Uhlobo lokuqala lwe-beta, olungasetshenziselwa ukwethula ezinye izinhlelo zokusebenza zangempela, luhlelelwe ukukhishwa engxenyeni yesibili yonyaka okhona.
Kulokhu okuthunyelwe ngu-Eben Upton, kukhombisa ukuthi umsebenzi usenziwe, kukhonjiswa unxantathu we-RGB.
Upton uphawula ukuthi lokhu kumelwa konxantathu yenguqulo ye-Broadcom VideoCore VI Vulkan ingubufakazi bokuthi "unxantathu ongenasici we-RGB, ithayili elilodwa" kusilawuli, noma kunjalo lesi sigaba sokuqala sentuthuko.
Okwamanje akukho ukufinyelela kwekhodi, kepha kunesithembiso sokuthi izotholakala ngokuhamba kwesikhathi. Yize ukumenyezelwa kokufika kweVulkan ku-Raspberry Pi, ithimba lezentuthuko likhuluma ukuthi lona ngumsebenzi wokuqala nje nokuthi kunomsebenzi omningi okufanele wenziwe.
Ngaphambi kokuba ujabule kakhulu, khumbula ukuthi lokhu kumane nje kuyisiqalo senqubo yokuthuthuka kweVulkan ku-Raspberry Pi. Ngenkathi kube nemizamo yomphakathi lapho kuqondiswa ukwesekwa kweVulkan (ekuqaleni kweVideoCore IV) kusukela ngonyaka we-2018, i-Igalia ibisebenza nje kuphela kulesi silawuli esisha amasonto ambalwa, futhi sisenomgwaqo omude kakhulu wentuthuko ophambi kwa.
Futhi, UKhronos umemezele isitifiketi sokulawula i-v3d Mesa (phambilini i-vc5), ebonwa njengehambisana ngokugcwele ne-OpenGL ES 3.1.
Isilawuli siqinisekisiwe nge-Broadcom BCM2711 chip esetshenziswa kumabhodi we-Raspberry Pi 4. Ukuthola isitifiketi kukuvumela ukuthi umemezele ngokusemthethweni ukusekelwa kwamazinga wehluzo futhi usebenzise izimpawu zokuhweba ezihambisanayo zeKhronos.
Ekugcineni, ukufika kwesilawuli seVulkan isikhulu se-Raspberry Pi Izosiza ukuthuthukisa ukusetshenziswa kwamandla, ukusebenza, kanye nokusatshalaliswa kwezinto eziningi.
Ngaphezu kwalokho, kuzozuzisa kakhulu ukuthuthukiswa ku-Raspberry Pi, njengoba iVulkan izonikeza izindlela ezintsha zokuthola ukusebenza okuhle kakhulu kwehadiwe.
Uma ufuna ukwazi kabanzi ngayo Mayelana nokuthunyelwe, ungabheka imininingwane yakho kufayela le- isixhumanisi esilandelayo.
