Intel's Mesa Driver Jumps Ahead To OpenGL 4.2

It was just yesterday that Intel's Mesa driver crossed the OpenGL 4.0 threshold while today it's jumped ahead to OpenGL 4.2.

Any reader getting their proper daily dose of Phoronix though will know it's just been one GL extension blocking OpenGL 4.1 and 4.2 compliance: ARB_vertex_attrib_64bit, which was being worked on at the same time as the related big GL 4.0 blocker: ARB_gpu_shader_fp64. Now that ARB_vertex_attrib_64bit landed today after ARB_gpu_shader_fp64 hit yesterday, the Intel driver is ready for showing off OpenGL 4.2 support with this next Mesa release.

The Intel OpenGL 4.2 support landed in Git this morning. With the next Mesa release not being delayed, the Mesa 11.3/12.0 release should happen as planned in June while the feature freeze is happening this week.

Blocking the Intel driver from OpenGL 4.3 is ARB_robust_buffer_access_behavior, but it's not clear that this extension will be done in time for the next release with the feature freeze being imminent. Nevertheless, it's fantastic to see this three-month release coming up jump the Intel driver from OpenGL 3.3 to 4.2 while also advancing the RadeonSI and Nouveau OpenGL matrix too.
