Michael Larabel at Phoronix has been assiduously reporting on some of the small advancements in open source 3-D graphics; in aggregate, those small advancements make for big improvements in hardware (and platform) support, as well as higher performance. Phoronix published today a year-end wrap-up highlighting some of the ways that Mesa has developed; it's quite a list. An excerpt: This time last year core Mesa and the drivers were still limited to OpenGL 3.3 compliance while in 2015 we've seen core Mesa reach up to OpenGL 4.2 support. The AMD RadeonSI and R600g drivers have raised up through OpenGL 4.1 (though R600g is limited in what supports GL4) and the Nouveau NVC0 driver is at OpenGL 4.1 as well. The Intel Mesa driver is still at OpenGL 3.3, but they are extremely close to OpenGL 4.2 and should hit that milestone in early 2016 after having been recently focusing up on OpenGL ES 3.1 support, which they did achieve this year. Besides tackling more GL4 support, Mesa this year has seen the new VirtIO GPU driver for 3D support in guest VMs, continued work on the new Raspberry Pi 3D driver (VC4), video encode/decode improvements, and other Gallium3D state tracker highlights.
