Following yesterday's article comparing the AMD Radeon Linux drivers on Ubuntu 12.10, Marek Olšák looked into some of the cases where the open-source Radeon Gallium3D driver was much slower than the proprietary Catalyst driver. Already with one patch that touches only two dozen lines of code, Marek was able to quadruple the open-source driver frame-rate for at least one game.

OpenGL support is becoming an increasing hard requirement on the Linux desktop. Even if your hardware comes up short, more desktops are requiring GL support, which means falling back to the CPU-based LLVMpipe Gallium3D driver.

While this morning I shared my views about nine good features of Mesa 9.0 for the major open-source OpenGL user-space update, there's also many disappointing items and shortcomings of this Mesa 9.0 release as it pertains to end-users running the open-source Linux graphics drivers.

With Mesa 9.0 having been released last night and in continuing in a similar manner to eight good things about Mesa 8.0 and eight shortcomings about Mesa 8.0 from its release, let's start off with nine good things about Mesa 9.0.
9 October 2012 - Mesa 9.0
After facing some delays, Mesa 9.0 was released on Monday afternoon as the latest bi-annual feature release of this important open-source OpenGL driver stack. This is also the first release that supports OpenGL 3.1, albeit the hardware support is currently limited to the Intel DRI driver.

The Linux OpenGL stack along with the upstream OpenGL specification has been evolving at a fast pace in recent years. There was recently some discussion within the Khronos camp for updating the guide for how to implement OpenGL support on Linux and it's been decided it will be talked about next week at XDC2012. To get the ball rolling for planning out a new Linux OpenGL ABI, NVIDIA has published a proposal.

Vincent Lejeune has shared a new Mesa branch that he's currently soliciting for comments as it introduces a new GLSL to LLVM pass. He hopes drivers will begin to use it, including the Intel driver with their new-found LLVM compiler ambitions.

Patches for supporting OpenGL Geometry Shaders within Mesa/Gallium3D are said to be published soon, which is a big step that will make Mesa closer to supporting the OpenGL 3.2 specification.
