On the Radeon and Nouveau side, perhaps we'll see OpenGL 4.2 working in the next two weeks, but it would be a huge miracle if all of the OpenGL 4.3 work was magically completed in time for Mesa 11.2.
#Xenia opengl 4.3 driver#
While it's possible that core Mesa will meet all the OpenGL 4.3 requirements before then, the Intel DRI driver will still likely be blocked by the FP64 support unless that code really gets wrapped up and lands in the next two weeks. Mesa 11.2 is set to be branched from Git later this month. The Nouveau NVC0 meanwhile is slightly ahead of the RadeonSI state thanks to recent advancements, but they still have a lot of work too before calling themselves OpenGL 4.3 compliant.

R600g is in a similar boat, but there only the Radeon HD 5800/6900 series support even OpenGL 4.1 right now due to having real FP64 support. After that, there are seven OpenGL extensions needed for RadeonSI to hit OpenGL 4.3 compliance. The RadeonSI Gallium3D driver is at OpenGL 4.1 currently but lacks ARB_shader_atomic_counters and ARB_shader_image_load_store support for OpenGL 4.2. (All OpenGL 4.2-specific changes are already complete on the Intel side.) However, the Intel driver still needs OpenGL 4.0's ARB_gpu_shader_fp64 and OpenGL 4.1's ARB_vertex_attrib_64bit extensions to catch up. Igalia implemented the ARB_internalformat_query2 for Intel (as they are in a business relationship), the Intel driver just needs ARB_robust_buffer_access_behavior, so will presumably reach GL 4.3 when that extension hits core Mesa. While hitting these two extensions will mark compliance for core Mesa, the actual hardware driver state varies. Assuming this big code review goes well for this extension work done by consulting firm Igalia, there is then just the GL_ARB_robust_buffer_access_behavior extension blocking OpenGL 4.3 exposure.

While as a user you might not care what ARB_internalformat_query2 is about, it's significant that this is just one of two extensions needing to land in Mesa Git before core Mesa will have OpenGL 4.3.
#Xenia opengl 4.3 Patch#
Mesa is now very close to OpenGL 4.3 compliance thanks to a massive patch series that was posted today for review.Įduardo Lima Mitev of Igalia posted a set of 65 patches today for implementing ARB_internalformat_query2 support within core Mesa and is implemented then within the Intel i965 DRI driver.
