Collabora employee and Mesa release manager Emil Velikov has announced the availability of Mesa 13.0-RC3 and he expects to do the final Mesa 13 release in a matter of hours.
Expert Mesa developer Marek Olšák at AMD is spending this weekend hacking on some new OpenGL threading code to benefit the open-source Radeon Linux driver stack.
Mesa release manager Emil Velikov has setup a tracker bug to indicate all of the bugs that are blockers for the upcoming Mesa 13.0 release.
In addition to RadeonSI re-enabling SDMA for Carrizo and Sea Islands GPUs yesterday, Marek Olšák made another change to fix the issue of random GPU hangs happening with Hawaii and Fiji graphics processors.
The latest Mesa 13.0 weekly release candidate is now available for testing.
While Mesa 13.0 is coming along for release next month with exciting features like OpenGL 4.5 for Intel, unofficial GL 4.4/4.5 for RadeonSI/NVC0, and the addition of the RADV Radeon Vulkan driver, there is some functionality that sadly won't be found in this release.
A short time after Mesa 13.0 was branched in Git yesterday, well known AMD open-source developer Marek Olšák was landing new work in master.
Now that release manager Emil Velikov has worked through his LLVM issue, Mesa 13.0 Release Candidate 1 is now officially available as the first development release that has core OpenGL 4.4/4.5 support in Mesa.
The Mesa 12.1/13.0 release dragged out a bit to allow the RADV Radeon Vulkan driver to be merged and then some Gallium3D Nine fixes, which have landed. The branching / feature freeze didn't happen last week though as planned, but Emil Velikov the release manager has now provided an update.
Stemming from an issue of slow performance inside LXDE's file manager, the Raspberry Pi VC4 Gallium3D driver has received an optimization for better texture upload performance.
Earlier this week was a discovery of a "serious performance fix" For the RadeonSI Gallium3D driver by disabling ReZ. That change landed in Mesa Git already so I ran some before/after benchmarks.
Chad Versace, the Intel OTC developer turned Googler who is part of the Chrome OS driver team, has been baking the EGL_MESA_platform_surfaceless extension and its implementation inside Mesa.
Intel's Mesa OpenGL driver now officially enables OpenGL 4.5 support for Broadwell "Gen 8" hardware and newer.
Mesa 3D development has been exciting this year with seeing OpenGL 4.3 support in Mesa 12.0 and the next Mesa release having OpenGL 4.4 and 4.5 support (pending the passing of the Khronos CTS conformance), which has meant a lot of new code going into Mesa. Aside from modernizing the OpenGL 4.x support by these open-source drivers, there's been the addition of the Intel and Radeon Vulkan drivers and much more.
With the Mesa 13.0 feature freeze expected to happen before the weekend, it's been another exciting day in the Git development tree of landing last-minute features for next month's Mesa release.
The work by Nicolai Hähnle on finishing up the GL_ARB_enhanced_layouts extension for Gallium3D is now in Git. This officially marks RadeonSI done with OpenGL 4.4 and is effectively done with OpenGL 4.5 although the new version string is yet to be advertised.
Now that the RADV Radeon Vulkan driver is part of mainline Mesa, it's increasingly easy to experiment with this unofficial, open-source Vulkan driver on rolling-release distributions and through third-party package archives/repositories.
Chad Versace, the former Intel OTC developer now employed by Google on the Chromium team, has published the latest patches for implementing the EGL_ANDROID_native_fence_sync extension within Mesa's Intel driver.
The 75 patches for Gallium3D's Nine state tracker improvements (D3D9) have now landed in Mesa Git master ahead of the branching for the next Mesa release at the end of the week.
Iago Toral Quiroga of Igalia has sent out the second version of his massive 103 patches for implementing FP64 support for Intel Haswell hardware within the i965 Mesa driver in order to expose OpenGL 4.0 support.
With catching up on the OpenGL extensions, Marek Olšák of AMD has been spending a fair amount of time on performance optimizations for the AMD's open-source OpenGL driver and some code that benefits Mesa as a whole too. One of his latest patch series is on optimizing Mesa's GLSL compiler performance.
Building off the exciting patches published Friday for completing ARB_enhanced_layouts that finish off the RadeonSI OpenGL 4.4~4.5 support, the Nouveau NVC0 support is basically done too with the finishing up of that final extension being done in the Mesa state tracker.
We've been expecting many last minute Gallium3D Nine / D3D9 patches ahead of the Mesa 13.0 branching and yesterday the bulk of those patches were sent out.
Pending no last minute issues, the RADV open-source Radeon Vulkan driver will be merged into mainline Mesa tomorrow.
José Fonseca of VMware has added basic support for AVX2 to Gallivm, the driver-independent portion of LLVM integration with Gallium3D.
Thanks to work done by AMD's Nicolai Hähnle, the Mesa Gallium3D state tracker exposes support for the GL_KHR_robustness extension.
On top of the RADV Vulkan driver being queued for the next Mesa release, it looks like some improvements to the "Nine" Direct3D 9 Gallium3D state tracker are also en route for the new Mesa version.
The latest version of the Mesa DRM library (libdrm) is now available and it's a fairly important release.
Beginning next year, Mesa developers so far appear favorable to moving towards a date-based versioning concept.
Following the mailing list talk over the past two days about doing the next Mesa release, plans are being discussed for releasing at the end of October and it might have just got a whole lot more exciting.
