Intel’s open-source Linux graphics driver developers are working on integrating support for cooperative array types on the Xe2 platform, which will be featured in the upcoming Lunar Lake processors and Battlemage discrete graphics cards. Ian Romanick’s work on this feature was recently merged into Mesa 24.2-devel, with support for Vulkan VK_KHR_cooperative_matrix extension. This support is crucial for accelerating machine learning tasks.
The VK_KHR_cooperative_matrix extension was introduced last year in Vulkan 1.3.255 to facilitate cooperative array types in SPIR-V integration. These arrays are used primarily in compute shaders, where the storage is distributed across all invocations for efficient matrix multiplications. This extension allows for the listing of supported array types and dimensions within the implementation.
Intel’s Xe2 Vulkan cooperative array support is now part of Mesa 24.2 Git, with additional details available in the merge request. This effort to enhance graphics processing capabilities aligns with Intel’s continued focus on innovation and performance in the open-source community.
In conclusion, the integration of cooperative array support for Xe2 platforms by Intel’s open-source Linux graphics driver developers marks a significant advancement in graphics processing technology. This feature will be essential for accelerating machine learning tasks and improving overall performance on upcoming Lunar Lake processors and Battlemage discrete graphics cards. Intel’s commitment to open-source development and innovation is evident in their continued efforts to enhance graphics capabilities and support within the Linux ecosystem.
