As a result of such practices, even if a graphics processor’s specification states that it supports OpenGL 2.1/3.0/3.3/4.3, it can still lack the necessary features to display Shaded/Virtual views. While a GPU or IGP can claim support for a certain OpenGL version, its manufacturer may have only integrated the minimum set of features required to claim support for that version – which may not be sufficient for Wysiwyg/Vivien’s requirements. What does “full support” for OpenGL mean? If OpenGL 2.1 is not fully-supported, the Shaded/Virtual View will not be usable. Beyond OpenGL 4.3, much of OpenGL 4.4 and 4.5 is left to be accomplished.For Wysiwyg and Vivien to be able to the Shaded and Virtual views, respectively, the computer must use a video card / graphics processor – whether this is a graphics processing unit (“GPU”) or an integrated graphics processor (“IGP”) – which fully-supports OpenGL version 2.1. During that round of distribution updates too is likely when seeing the first out-of-the-box Vulkan support as well. So hopefully by this summer there will be Radeon/Nouveau support for OpenGL 4.3, assuming you're on a rolling release distribution or are comfortable in using third-party repositories or building Mesa yourself, otherwise it likely won't be until this fall when you'll see out-of-the-box OpenGL 4.3 support on the Linux desktop. Thus this moves the OpenGL 4.3 target out three more months per Mesa's usual release cadence. 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.

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.
#Opengl 4.3 support is required 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.
