Collabora na-emepụta ihe mgbakwunye maka ịgba ọsọ OpenCL na OpenGL n'elu DirectX

Mmekọrịta ụlọ ọrụ ọkọnọ onye ọkwọ ụgbọ ala Gallium ọhụrụ maka Mesa, nke na-arụ ọrụ oyi akwa maka ịhazi ọrụ OpenCL 1.2 na OpenGL 3.3 API n'elu ndị ọkwọ ụgbọ ala na-akwado DirectX 12 (D3D12). Koodu bipụtara n'okpuru ikike MIT.

Ọkwọ ụgbọala a chọrọ na-enye gị ohere iji Mesa na ngwaọrụ ndị na-akwadoghị OpenCL na OpenGL, yana dịka mmalite maka ibubata ngwa OpenGL/OpenCL ka ọ na-agba n'elu D3D12. Maka ndị na-emepụta GPU, subsystem na-eme ka o kwe omume ịnye nkwado maka OpenCL na OpenGL, ma ọ bụrụ na ọ bụ naanị ndị ọkwọ ụgbọala nwere nkwado D3D12 dị.

Otu n'ime atụmatụ ndị a na-eme ozugbo bụ mmezu nke ịgafe n'ụzọ zuru ezu nke ule ndakọrịta nke OpenCL 1.2 na OpenGL 3.3, ịlele ndakọrịta na ngwa yana nsonye mmepe na ihe mejupụtara Mesa. A na-emekọ mmepe na ndị injinia Microsoft na-emepe emepe meghee ngwá ọrụ D3D11N12 maka ibufe egwuregwu site na D3D11 gaa na D3D12 na ọba akwụkwọ D3D12TranslationLayer, nke na-arụ ọrụ primitives ọkọlọtọ ọkọlọtọ n'elu D3D12.

Mmejuputa a na-agụnye onye ọkwọ ụgbọ ala Gallium, OpenCL compiler, OpenCL Runtime na NIR-to-DXIL shader compiler, nke na-agbanwe ihe nnọchianya nke NIR shaders eji na Mesa n'ime DXIL (DirectX Intermediate Language) usoro ọnụọgụ abụọ, kwadoro na DirectX 12 ma dabere na ya.

Kama Clover, OpenCL mmejuputa a na-eji na Mesa, a na-atụpụta oge ọhụrụ OpenCL, na-enye ohere ka mgbanwe ndị ọzọ na DirectX 12 API.

A na-akwado ndị ọkwọ ụgbọala OpenCL na OpenGL site na iji interface Gallium enyere na Mesa, nke na-enye gị ohere ịmepụta ndị ọkwọ ụgbọ ala na-abanyeghị na nkọwa nke OpenGL wee tụgharịa oku OpenGL n'isi nso na eserese eserese nke GPU ọgbara ọhụrụ na-arụ ọrụ.
