Xov xwm hais txog Intel GPU: tshiab NEO OpenCL, Vulkan extensions, lub npe ntawm tus tshiab PCH, Gallium tsav tsheb nce qib, eDRAM rau thav duab tsis caching

Tsav Tsheb NEO OpenCL los ntawm Intel hloov tshiab rau version 19.20.13008. Nws muab OpenCL 2.1 kev txhawb nqa rau Intel GPUs pib nrog Broadwell. Cov uas muaj Haswell lossis laus dua GPU raug txhawb kom siv Beignet tsav tsheb, uas yog Txoj Cai.

Ntawm cov kev hloov pauv: Intel Graphic Compiler tau hloov kho mus rau qhov tseeb version 1.0.4.

Kev Txhim Kho Cov Lus Qhia, sib dhos cov lus qhia hauv CentOS 7. Daim ntawv tso tawm: Fine grained SVM tsis txhawb hauv qhov kev tso tawm no. Yog tias koj muaj Ubuntu 16.04.4 thiab lub default kernel 4.13, tom qab ntawd rau CFL platforms koj yuav tsum tau ntxiv cov kernel parameter i915.alpha_support=1

Lub Peb Hlis Ntuj, ua tsaug Intel qhib qhov chaw tsav tsheb, nws tau paub txog SoC Intel Elkhart Lake tshiab. Tam sim no, ua tsaug rau lawv, nws pib paub npe code PCH, uas yuav siv rau hauv lawv - Mule Creek Canyon.

Vulkan tau tso tawm 1.1.109, uas suav nrog ob qhov txuas ntxiv tshiab los ntawm Intel:

• VK_INTEL_performance_query - Qhov txuas ntxiv no tso cai rau ib daim ntawv thov los ntes cov ntaub ntawv kev ua tau zoo rau cov tsev qiv ntawv ntxiv / daim ntawv thov tshwj xeeb analytics. Qhov kev txuas ntxiv no yuav raug siv los ntawm Intel Graphics Performance Analyzers thiab Intel Metrics Discovery lub tsev qiv ntawv. Qhov kev txuas ntxiv no kuj tseem yuav muaj txiaj ntsig zoo rau kev txheeb xyuas thib peb / cov khoom siv ua haujlwm
• VK_INTEL_shader_integer_functions2 - Qhov txuas ntxiv no ntxiv cov lus qhia lej tshiab rau SPIR-V, zoo ib yam li GLSL txuas ntxiv rau OpenGL INTEL_shader_integer_functions2

Hauv Intel "Iris" Gallium3D tsav tsheb rau Linux tshwm sim Shader disk cache kev them nyiaj yug. Yav dhau los, qhov no muaj nyob hauv Classic Mesa tsav tsheb rau Linux. Kev them nyiaj yug yuav tsum tau nyob hauv Mesa 19.2.

Thaum kawg, Intel ua haujlwm ntawm kev siv cov kev ua haujlwm siab eLLC / eDRAM nco rau sau-rov qab caching ntawm cov zaub buffers. Qhov no yuav ua haujlwm ntawm Skylake thiab tshiab dua, tab sis tsis yog ntawm cov chips qub uas tseem muaj eDRAM.
