Understanding More Of The Shader Storage Buffer In Mesa

Iago Toral of consulting firm Igalia has been working on ARB_shader_storage_buffer object support in Mesa the past few months. This extension is needed for OpenGL 4.3 and is a buffer that allows for bidirectional communication between the CPU and GPU space and perform random access reads/writes and atomic operations on variables within the buffer objects.

LLVMpipe FP64 Support Knocks Off Some GL4 Extensions

While LLVMpipe tends to be an afterthought in supporting new OpenGL extensions within Mesa/Gallium3D and is in need of some help, David Airlie managed to land some improvements for it today in Mesa by adding support for double-precision floating-points.

ILO Gallium3D Continues Marching To Its Own Beat

While it doesn't have the backing of Intel Corp, the ILO Gallium3D driver continues to advance on its own for bringing HD/Iris Graphics to Gallium3D as an alternative open-source driver to the i965 Mesa DRI driver.

OpenGL 4.3's Arrays-of-Arrays Getting Back On Track For Mesa

Back in 2013 Timothy Arceri sought crowd-funding to work on another OpenGL extension for Mesa: GL_ARB_arrays_of_arrays. While progress was made on this OpenGL 4.3 extension, the "AoA" support has yet to be merged to mainline but progress is being made.

Gallium3D's LLVMpipe Could Use Some Help

While the LLVMpipe driver is commonly used these days as a software fall-back driver on numerous Linux distributions in cases where no hardware GPU driver is available or working, the LLVMpipe state leaves a lot to be desired. In addition to it benefiting from any speed improvements, there's also lots of help it could use on implementing newer OpenGL support.

Marek Posts Mesa Tessellation Support For RadeonSI Gallium3D

It looks like OpenGL tessellation shader support within Mesa/Gallium3D is finally about to become a reality! Prolific Mesa contributor Marek Olšák has finished up the enablement work started by others and now has OpenGL tessellation working with the AMD RadeonSI Gallium3D open-source graphics driver.

Optimus/Primus Regresses On Latest Mesa 10.5.5 Release

A Phoronix reader has pointed out that a regression has slipped into the Mesa 10.5.5 point release that negatively affects users of dual-GPU laptop owners with NVIDIA Optimus technology that are using the open-source "Primus" code for running OpenGL games on the alternate graphics processor.

Features Added To Mesa 10.6 For Open-Source GPU Drivers

Mesa 10.6 is up to a release candidate state and should be officially released in early June. If you're not up to speed on this quarterly update to the open-source user-space graphics drivers, here's an overview of the new features for Mesa 10.6.

Intel Skylake Adds ASTC Texture Compression, Open-Source Support Coming

S3TC remains the most common form of texture compression relied upon by video game developers and others, but it remains a legal mess for open-source graphics drivers. ETC2 texture compression isn't faced by legal issues but was only mandated by OpenGL ES 3.0 / OpenGL 4.3, which makes it less well adopted. Meanwhile, in looking forward to the future, ASTC is the royalty-free next-gen texture compression solution that's backed by the Khronos Group. Intel's forthcoming Skylake hardware will make ASTC a much more widespread reality.
