Gallium3D's LLVMpipe Tacks On Another OpenGL 4 Extension

Most often when talking of new OpenGL 4 extensions in Mesa it tends to be regarding the Intel Mesa driver given they're the company investing the most into the Linux graphics stack, followed by the Radeon and Noveau drivers. However, this week in Mesa is some love to the fallback/debugging software rasterizers.

OpenGL 4.1 Extension Implemented For Intel Mesa Sandy Bridge

In January of 2014 there was ARB_viewport_array added to the Intel Mesa driver, an extension needed for OpenGL 4.1 compliance, but at the time it was only enabled for Ivy Bridge graphics hardware and newer. Intel has now extended that support back to Sandy Bridge.

Nouveau NVC0 Gallium3D Driver Now Exposes GLSL 4.10

While there's still more work to be done before advertising OpenGL 4.0~4.1 compliance, the Nouveau NVC0 Gallium3D driver is now advertising support for GLSL 410 (4.10), the GL Shading Language version to match OpenGL 4.1.

Gallium3D's HUD Gets New Customization Options

For the past two years there has been an optional Gallium3D HUD to display various performance-related metrics as an overlay while running OpenGL applications with the Gallium3D drivers. With the latest Mesa Git code, the heads-up display can be a bit more customized.

Mesa's Android Support Is Currently In Bad Shape

While Mesa is talked about as being able to be built for Google's Android operating system to run these open-source graphics drivers on Android devices with OpenGL ES support, in reality there's a lot left to be desired.

More Fedora/Ubuntu Linux vs. OS X OpenGL Benchmarks

Earlier this week I shared some new OS X 10.10 vs. Fedora 21 vs. Ubuntu 15.04 benchmarks, which were quite interesting and Linux ended up having the upper-hand on this new Mac Mini with an Intel "Haswell" CPU sporting Iris Graphics. For those interested in more cross-OS benchmarks with Intel Iris Graphics, here's some additional results.

OpenGL Direct State Access Materializing In Mesa

While Mesa still doesn't officially support the OpenGL 4.0 specification, the Direct State Access (DSA) extension of OpenGL 4.5 has been worked on quite a bit so far and the Mesa implementation is nearly done.

LunarGLASS Adds Experimental SPIR-V Front-End

LunarG, the consulting company around open-source Linux graphics drivers, is one of the organizations involved heavily with the new Vulkan graphics API and SPIR-V intermediate representation. Thanks to their involvement, they already have out an initial SPIR-V front-end to their open-source LunarGLASS Mesa project.
