Intel open source graphics drivers are now OpenGL 4.5 certified

The release of Mesa 17.0 yesterday marked a very important milestone: the fully open source graphics platform for Intel integrated processors was released, for the first time, with industry certification of conformance with the latest versions of standard 3D graphics APIs.

The Khronos Group, an industry consortium that defines and promotes open standards for cross-platform technology, has granted the latest generations of Intel® Core™ processors with recognition of their conformance to the OpenGL 4.5, OpenGL ES 3.2 and Vulkan 1.0 standards.

Igalia has contributed several features and bugfixes that helped achieve this important milestone. During the last several months, we have been working hard on improving the Intel driver to enable 64-bit floating point support. We developed OpenGL extensions such as ARB_gpu_shader_fp64 and ARB_vertex_attrib_64bit, which were a major contributor to increasing the supported OpenGL version. This work that has also benefited the Vulkan driver. Earlier on, we developed ARB_internalformat_query2 and ARB_shader_storage_buffer_object, which were also required by different core versions of OpenGL.

Igalia also worked side-by-side with Intel engineers on bugfixes across different parts of the stack, improving the quality and maturity of the driver in order to get it to the level of quality required by the Khronos conformance certification process. As members of the Khronos Group, we also had the opportunity to contribute tests and bugfixes to the conformance suite itself. We believe that the ability to work vertically with different industry actors was key for the success of this certification process, and it gives us a unique position in the industry.

We are honored by the opportunity to work with great industry partners such as Intel, and also very proud of our contributions to the open source Linux graphics stack.
