Is Upgrading To Mesa 11.1-devel Worthwhile For Radeon R600g Users?

With last week's release of Ubuntu 15.10, Mesa 11.0 is part of the open-source graphics stack. Unfortunate for those with an AMD GCN GPU that uses the RadeonSI Gallium3D driver, Mesa 11.0 on Ubuntu 15.10 is built against an older version of LLVM that doesn't allow the OpenGL 4.1 support to be exposed. For RadeonSI users, I'd say switching to Mesa 11.1-devel + LLVM 3.8 SVN is almost a must once installing Ubuntu 15.10, but is it worthwhile for R600g users?

VirGL VirtIO 3D GPU Driver Added To Gallium3D

The open-souce QEMU/KVM stack with VirtIO will finally be able to have guest 3D/OpenGL acceleration that's backed by the GPU/driver of the host system! While VMware and VirtualBox have long had guest 3D support backed by the host's hardware, it's taken a while for the open-source Linux virtualization stack to gain this functionality.

Intel Is Making A High-Performance Software Rasterizer For Mesa

While Mesa currently has the swrast, LLVMpipe, and Softpipe drivers as software rasterizers that run OpenGL on the CPU rather than any dedicated GPU, a team at Intel has been developing a new, high-performance software rasterizer. This Intel team hopes to upstream their new "OpenSWR" project into Mesa as offering fast, CPU-rendered graphics.

New SVGA Gallium3D HUD Options Added For VMWare Users

For those that don't know or may have forgot, Gallium3D has a Heads-Up Display (HUD) for showing various driver metrics while running OpenGL games/applications. If you're an SVGA VMware user, there's some new HUD queries available.

Writing Good Bug Reports For Open-Source GPU Drivers

While most Phoronix readers should be well aware of the bug reporting procedures for Mesa drivers, Ian Romanick of Intel has written a lengthy blog post about the process of writing a "good" bug report for the open-source graphics drivers.

Ubuntu PPA Updated With Mesa Git + LLVM 3.8 SVN

While Ubuntu 15.10 has Mesa 11.0 and it provides OpenGL 4 support for the Nouveau driver, it doesn't for RadeonSI. The issue is that in Ubuntu 15.10 is still an older version of LLVM that in the AMDGPU LLVM back-end lacks the needed support for OpenGL 4.0/4.1 compliance. Fortunately, a PPA has been updated for Ubuntu Wily with said support.

With GL 4.3 AoA Getting Done, Arceri Is Trying A GL 4.4 Extension

Timothy Arceri is the independent developer that started out doing some crowd-funded Mesa OpenGL extension development that was successful so he did a second crowd-funding campaign to do more Mesa feature work. That second extension, ARB_arrays_of_arrays, finally appears nearly complete so he's decided to work on another extension.
