Gallium3D's video acceleration code for VA-API VDPAU state tracker were upgraded today with support for DRI3.
This weekend was the ambitious proposal to delay Mesa 12.0 until there's OpenGL 4.5 support in this open-source driver stack, which could tack on around an extra month to the release schedule. It's now looking like this change in release planning will not happen.
There's traction building around delaying the next Mesa release, which is currently scheduled to be out in June and for a feature freeze in just a few days. A new proposal is to make Mesa 12.0 be the release with initial OpenGL 4.5 support.
Axel Davy who has been one of the prolific developers involved on the "Nine" Gallium3D state tracker for providing a basic Direct3D 9 implementation under Linux has sent in a set of 39 patches that he hopes to land in time for next month's Mesa release.
Yet another feature landing in Mesa Git ahead of the upcoming Mesa 11.3/12.0 branching for release next month is lossless compression in the Intel Mesa DRI driver.
There are new Mesa happenings in the OpenGL Vendor Neutral Dispatch Library (GLVND) space.
With perfect timing now that the Radeon DDX enables DRI3 by default, Leo Liu of AMD has posted patches for implementing DRI3 support within the VA-API and VDPAU Gallium3D components.
There is more exciting open-source AMD work to share today, a week before the feature freeze for the next version of Mesa.
Bas Nieuwenhuizen has announced his work on "offchip tessellation" support for the RadeonSI Gallium3D driver to provide dramatically better OpenGL tessellation performance.
Mesa release manager Emil Velikov of Collabora has announced the release of Mesa 11.2.2, the newest stable point release for this user-space stack to the open-source graphics drivers.
With the latest code landing in Mesa Git this afternoon, the GL_ARB_query_buffer_object has been wired up for Intel's i965 OpenGL driver.
Red Hat developer Rob Clark has put out a new update concerning the status of his pet project, Freedreno, for providing open-source, reverse-engineered graphics support for Qualcomm Adreno hardware.
Timothy Arceri of Collabora has been restoring work on an on-disk shader cache for Intel's open-source Mesa OpenGL driver that was originally started by some of the Intel OTC driver developers.
Going along with the work written about yesterday of Igalia Posts Intel vertex_attrib_64bit Mesa Driver Patches, Close To OpenGL 4.1+, the latest ARB_gpu_shader_fp64 patches were published today for the Intel i965 Mesa driver.
For x86 Android users, patches are available for making use of Mesa's LLVMpipe driver in Gallium3D for cases where hardware drivers are not available. This support is reportedly good enough for running Android apps in the absence of proper OpenGL drivers.
Mesa release manager Emil Velikov has laid out plans to release the next version of Mesa in just over one month.
It turns out that Skylake's HD Graphics 510, HD Graphics 535, Iris Graphics 550, and Iris Graphics P555 were missing their open-source driver support from an important piece of the Linux graphics stack.
Marek Olšák's latest big patch series has landed.
The AMD RadeonSI Gallium3D driver for GCN GPUs now has support for OpenGL Compute Shaders within the latest Mesa code!
Mesa 11.2.1 is now available as the first maintenance release for Mesa 11.2.
It seems more and more independent developers are interested in getting involved in Mesa open-source graphics driver development, but aren't really sure where to start or what are some easy tasks to get started.
For those that missed the notice, Intel's Vulkan driver will soon be merging into mainline Mesa.
Mesa release manager Emil Velikov at Collabora announced the release candidate today of the forthcoming Mesa 11.2.1.
For those anxious to see compute shaders for then having OpenGL 4.3 support by the RadeonSI Gallium3D driver for GCN GPUs, the latest patches have been published.
As the last update of the day from AMD RadeonSI Gallium3D Is Now Incredibly Close To OpenGL 4.3, things are looking great with RadeonSI soon hitting OpenGL 4.3 but today the latest commits have now verified the OpenGL 4.2 compliance.
There is another OpenGL 4.3 extension crossed off the TODO list of the AMD RadeonSI Gallium3D driver for GCN GPUs.
Back in December a patch rolled out for supporting ETC2 and ASTC texture compression by the Nouveau NVC0 Gallium3D driver. Today that patch was finally merged for benefiting newer NVIDIA GPUs.
