Ettev\u00f5te Collabora esitles<\/a><\/noindex> uus Gallium draiver Mesa jaoks, mis rakendab vahetasandi avatud API OpenCL 1.2 ja OpenGL 3.3 jaoks D3D12 draiverite peal. Kood avaldati<\/a><\/noindex> MIT litsentsi alusel.<\/p>\n

Pakutud draiver v\u00f5imaldab kasutada Mesat seadmetes, mis algselt ei toeta OpenCL ja OpenGL, ning samuti toimib see l\u00e4htepunktina OpenGL\/OpenCL rakenduste portimiseks D3D12 peale. GPU tootjatele annab see v\u00f5imaluse pakkuda OpenCL ja OpenGL tuge, kui olemas on ainult D3D12 draiverid. <\/p>\n

L\u00e4himaid plaane on saavutada t\u00e4ielik \u00fchilduvuse testimine OpenCL 1.2 ja OpenGL 3.3, kontrollida \u00fchilduvust rakendustega ning kaasata arengud Mesa p\u00f5hikoosseisu. Arendus k\u00e4ib koost\u00f6\u00f6s Microsofti inseneridega. avatud<\/a><\/noindex> t\u00f6\u00f6riistakomplekt D3D11On12<\/a><\/noindex> m\u00e4ngude t\u00f5lkimiseks D3D11 pealt D3D12 ja raamatukogule D3D12TranslationLayer<\/a><\/noindex>, mis rakendab standardseid graafilisi primitiive D3D12 peal. <\/p>\n

Teostus sisaldab Gallium draiverit, OpenCL kompilaatorit, OpenCL runtime'i ja NIR-to-DXIL \u0161ifreerimisel rajatud \u0161ifrite kompilaatorit, mis muudab Mesas kasutatava vahevormi NIR DXIL (DirectX Intermediate Language) binaarformaatideks, mida toetatakse DirectX 12-s ja mis p\u00f5hineb LLVM 3.7 bitikoodil (DirectX Shader Compiler<\/a><\/noindex> Microsofti poolt, 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 laiendusega l\u00e4htekoodid kompileeritakse clang'i kaudu vahepealseks pseudokoodiks LLVM (LLVM IR), mis siis muudetakse OpenCL tuumade vahevormiks SPIR-V formaadis. SPIR-V formaadis tuumad edastatakse Mesale, t\u00f5lgitakse NIR formaati, optimeeritakse ja edastatakse NIR-to-DXIL-le, et genereerida arvutus\u0161ifrid DXIL formaadis, mis on sobilik GPU-l t\u00e4itmiseks kasutades DirectX 12 p\u00f5hist runtime'i.
\nClover'i asemel, mida kasutatakse Mesas OpenCL rakenduses, on pakutud uus OpenCL runtime, mis v\u00f5imaldab rohkem otseseid teisendusi DirectX 12 API-sse.<\/p>\n

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

OpenCL ja OpenGL draiverid on ette valmistatud, kasutades Mesas pakutavat Gallium liidest, mis v\u00f5imaldab draivereid luues mitte s\u00fcveneda OpenGL spetsiifilistesse detailidesse ja t\u00f5lkida OpenGL kutsed entiteetideks, mis on l\u00e4hemal graafilistele primitiividele, millega t\u00e4nap\u00e4eva GPU-d t\u00f6\u00f6tavad. Gallium draiver v\u00f5tab vastu OpenGL k\u00e4sud ja kaasab NIR-to-DXIL t\u00f5lkija.
\nkujundab k\u00e4su puhverid, mida t\u00e4idetakse GPU-l, kasutades D3D12 draiverit.<\/p>\n
