Ettev\u00f5te Collabora esituse<\/a><\/noindex> uus Gallium-draiver Mesa jaoks, mis rakendab kihistust API OpenCL 1.2 ja OpenGL 3.3 t\u00f6\u00f6tamiseks D3D12 (DirectX 12) toetavate draiverite kohal. Kood avaldatud<\/a><\/noindex> on MIT litsentsi all.<\/p>\n

Pakutud draiver v\u00f5imaldab kasutada Mesat seadmetes, mis algselt ei toeta OpenCL ja OpenGL, ning teenib ka stardipositiivina OpenGL\/OpenCL rakenduste portimiseks D3D12 t\u00f6\u00f6tamiseks. GPU tootjatele annab alams\u00fcsteem v\u00f5imaluse pakkuda tuge OpenCL ja OpenGL, kui olemas on ainult D3D12 toetavad draiverid. <\/p>\n

L\u00e4hiaja plaanidest mainitakse OpenCL 1.2 ja OpenGL 3.3 \u00fchilduvustestide t\u00e4ielikku l\u00e4bit\u00f6\u00f6tamist, rakendustega \u00fchilduvuse kontrollimist ja nende arenduste lisamist Mesa p\u00f5hikoosseisu. Arendus k\u00e4ib koost\u00f6\u00f6s Microsofti inseneridega, kes arendavad avatud<\/a><\/noindex> t\u00f6\u00f6riistakomplekt D3D11On12<\/a><\/noindex> m\u00e4ngude \u00fclekandmiseks D3D11-lt D3D12-ks ning raamatukogu D3D12TranslationLayer<\/a><\/noindex>, mis rakendab t\u00fc\u00fcpilisi graafilisi primitiive D3D12 kohal. <\/p>\n

Realiseerimine sisaldab Galliumi draiverit, OpenCL kompilaatorit, OpenCL jooksutegurit ja NIR-to-DXIL shaderite kompilaatorit, mis muundab Mesas kasutatava NIR shaderite vahepealse esitusviisi DXIL (DirectX Intermediate Language) binaarvormingusse, mida toetatakse DirectX 12-s ja mis p\u00f5hineb LLVM 3.7 bitikoodil (DirectX Shader Compiler<\/a><\/noindex> Microsoftilt, mis on p\u00f5him\u00f5tteliselt laiendatud forkk LLVM 3.7). OpenCL kompilaator on valmistatud LLVM projekti ja t\u00f6\u00f6riistade p\u00f5hjal SPIRV-LLVM<\/a><\/noindex>.<\/p>\n

OpenCL laienditega l\u00e4htekoodid kompileeritakse clangiga vahepealseks pseudokoodiks LLVM (LLVM IR), mis seej\u00e4rel muundatakse OpenCL tuumade vahepealseks esituseks SPIR-V formaadis. SPIR-V esituses olevad tuumad edastatakse Mesasse, koonduvad NIR formaati, optimeeritakse ja edastatakse NIR-to-DXIL-le, et genereerida DXIL formaadis arvutusshadereid, mis on sobivad GPU-l t\u00f6\u00f6tamiseks DirectX 12 baasil p\u00f5hineva jooksuteguri abil.
\nCloveri, mida kasutatakse Mesas OpenCL rakenduses, asemel on pakutud uus OpenCL jooksutegur, mis v\u00f5imaldab rohkem otseseid muundamisi DirectX 12 API-sse.<\/p>\n

\"Collabora<\/a><\/noindex><\/center><\/p>\n

OpenCL ja OpenGL draiverid on koostatud Mesa Gallium liidese abil, mis v\u00f5imaldab draivereid luua s\u00fcvenemata OpenGL spetsiifilistesse detailidesse ning t\u00f5lkida OpenGL loodud kutseid kaasaegsete GPU-de graafikute elementideks. Gallium-draiver v\u00f5tab vastu OpenGL k\u00e4sud ja kasutab NIR-to-DXIL t\u00f5lkijat.
\nsee kujundab k\u00e4su puusid, mida t\u00e4idetakse GPU-l, kasutades D3D12 draiverit.<\/p>\n
