Linux/Graphics: Intel, Mesa, and Gallium3D
Linus had pulled in these changes but then decided to unpull it for not enough testing. Linus wrote, “So I pulled it, but then checked, None of this was in linux-next 20171117 either, So I unpulled it.”
Topi Pohjolainen of Intel has been working on adding proper FP16/half-precision support to Mesa’s GLSL code.
Building off the work by Mario Kleiner, AMD developer Marek Olšák has been working on 10-bit color visual support within Mesa/Gallium3D.
Currently housed within Marek’s Git branch are the patches by Mario and him for supporting 10-bit color visuals properly within Mesa and wired through for Gallium3D. With 10-bit color visuals, it’s basically going from 256 luminosity levels per color/channel with 8-bit to 1024 levels. Most graphics cards going back years have supported 10-bit color visuals while the number of monitors supporting 10-bit colors has been much more limited until recently.
Making the rounds this weekend online as a “new” ARM Mali open-source driver is what we wrote about back in June as A New Mali-400 Open-Source Graphics Driver Is In Development.
