Ntọhapụ nke Mesa 20.1.0, mmejuputa OpenGL na Vulkan n'efu

Ewebata mwepụta nke mmejuputa iwu OpenGL na Vulkan API - Mesa 20.1.0. Mwepụta mbụ nke ngalaba Mesa 20.1.0 nwere ọnọdụ nnwale - mgbe nkwado ikpeazụ nke koodu ahụ gasịrị, a ga-ahapụ ụdị 20.1.1 kwụsiri ike. Na Mesa 20.1 emejuputa atumatu nkwado OpenGL 4.6 zuru ezu maka Intel (i965, iris) na AMD (radeonsi) GPUs, nkwado OpenGL 4.5 maka AMD (r600) na NVIDIA (nvc0) GPUs, OpenGL 4.3 maka virgl (GPU mebere GPU). Virgil3D maka QEMU/KVM), yana nkwado Vulkan 1.2 maka kaadị Intel na AMD.

N'etiti mgbanwe:

• agbakwunyere Igwe nhọpụta nhọrọ ngwaọrụ na-arụ ọrụ maka Vulkan API na sistemu nwere ọtụtụ GPU nwere Vulkan, na-arụ ọrụ n'otu aka ahụ na DRI_PRIME maka OpenGL. Iji họrọ ọkwọ ụgbọala na-arụ ọrụ yana GPU, a na-enye mgbanwe gburugburu MESA_VK_DEVICE_SELECT (ọ bụrụ na etinyeghị ya, a na-eji DRI_PRIME).

• Nkwado vectorization agbakwunyere na mbụ maka ibe AMD maka ibe eserese Intel ỌR., ihe nnọchianya nke enweghị ụdị (IR) nke shaders iji rụọ ọrụ na ọkwa kachasị ala, n'okpuru GLSL IR na Mesa's inside IR. N'akụkụ bara uru, n'ihi njikarịcha nke shaders, mgbanwe ahụ mere ka o kwe omume ịbawanye arụmọrụ nke OpenGL na Vulkan n'ọtụtụ egwuregwu na sistemụ nwere Intel GPUs. Dịka ọmụmaatụ, na egwuregwu
