Intel's open-source driver developers remain very busy this holiday season and hopefully in time for Mesa 22.0 next quarter they will have the DG2/Alchemist graphics support all ironed out with its feature-set and ready for those graphics cards to begin shipping, reportedly still in Q1. This gets the newly-introduced Vulkan dynamic rendering support ready for Intel's Vulkan driver. Separately but in other Intel Mesa news, also pending is VK_KHR_dynamic_rendering for ANV. Those curious for more extensive background information on task and mesh shaders can see NVIDIA's original developer introduction to the functionality they introduced back in 2018. Merged on Friday were the Intel Mesa compiler side changes for supporting not only supporting mesh shaders but also task shaders. Intel Xe HPG meanwhile is expected to have the hardware support for mesh shaders and the open-source driver support there is coming together. NVIDIA has supported mesh shaders going back to Turing GPUs while AMD RDNA2 GPUs also support mesh shaders but not exposed yet by the open-source Vulkan driver. Then wait a minute or so while it installs the old driver. This should give you a choice of drivers, proceed to select the oldest driver.
SHADER MODEL 3.0 FREE UPDATE
When the task and mesh shaders are drawn, they replace the standard programmable vertex processing pipeline, including vertex array attribute fetching, vertex shader processing, tessellation, and the geometry shader processing." Right click the video card then click Update Driver. As outlined in the spec, " This extension provides a new mechanism allowing applications to use two new programmable shader types - the task and mesh shader - to generate collections of geometric primitives to be processed by fixed-function primitive assembly and rasterization logic. In recent months Intel has been working on mesh shader support as part of SPV_NV_mesh_shader / GL_NV_mesh_shader. Ahead of Intel ARC graphics cards premiering next year, Intel's open-source Linux graphics driver developers remain very busy preparing for the next-generation graphics capabilities.
