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.

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.

Is Slow Patch Review For Mesa Driving Away Developers?

While most everyone would agree Mesa could benefit from more developers of this important piece of the open-source Linux desktop stack for providing OpenGL/3D graphics drivers, it seems slow patch review times are frustrating at least some casual developers wanting to contribute.
