It's been recently elaborated why the likes of FreeSync support over HDMI aren't coming to the open-source drivers, at least not yet... It stems from the decision by the HDMI Forum to prevent public access to the HDMI specification, which in turn is hurting open-source graphics drivers...
While LLVM 12.0 should be out around March as the next half-year feature update to this innovative and widely-used open-source compiler stack, LLVM 11.0.1 is now being christened as the only planned stable point release to LLVM 11...
Adding to the long list of changes for Mesa 21.0 is the Panfrost Gallium3D driver that provides open-source OpenGL for Arm Mali graphics hardware now supporting Arm Frame Buffer Compression (AFBC) for Bifrost GPUs...
While Intel has Clear Linux as an aggressively optimized Linux distribution catering towards their hardware, there isn't a direct equivalent for optimally showcasing the performance potential of current AMD platforms. Clear Linux often offers leading performance on Zen CPUs but that is obviously not by design but just an artifact of a lot in common between the latest Intel and AMD microarchitecture features. One of the few distributions (or only notable one) offering specific AMD Zen optimized builds has been OpenMandriva. With the OpenMandriva Lx 4.2 release candidate shipping this week, I ran some fresh benchmarks looking at how OpenMandriva Lx 4.2 RC1 compares between its generic x86_64 image and that of the Zen optimized build as well as in turn how that performance compares to Clear Linux and Ubuntu 20.10.
As we have been expecting in recent weeks, Wasmer 1.0 has been released as the "universal WebAssembly runtime" for helping to accelerate WASM adoption and new use-cases outside of the web browser...
Fedora 34 remains under active feature development and another batch of features were unanimously approved of by the Fedora Engineering and Steering Committee...
While for months there have been experimental patches taking Zink to OpenGL 4.6 for this OpenGL-on-Vulkan translation layer integrated into Mesa, the upstreaming process around testing and code review is quite lengthy with up until today still only exposing OpenGL 3.3 with mainline Mesa. But with the latest Git commits, Zink is now up to OpenGL 4.1...

As we reported almost one year ago, Red Hat was looking at likely dropping older x86_64 CPU support from Red Hat Enterprise Linux 9 and we now have a better idea of their plans in catering RHEL9 better to modern processors...
While many Linux users were excited when finding out the open-source AMD Radeon Linux drivers were allowing Smart Access Memory (Resizable BAR) support on older motherboards/CPUs and older Radeon GPUs rather than basically the very latest AMD products as seen on Windows, there is a change of course due to bugs. Now, officially, Mesa 21.0 is just enabling Smart Access Memory for systems with AMD Zen 3 processors and RDNA 2 graphics cards though if you have other hardware you can force-enable it...

As part of their fundamental shift to restrict Qt LTS point releases to commercial customers, The Qt Company is closing the Qt 5.15 branch to the public tomorrow with future Qt 5.15 LTS point releases to be restricted to paying licensees...
Back on Christmas I wrote about Linux 5.11 regressing for AMD performance on Zen 2 and newer systems where the just-added CPU frequency invariance support was often hurting various workloads when using the default "Schedutil" scheduler utilization frequency scaling governor. Since then and through the holidays I have been carrying out many more benchmarks looking at the Linux 5.11 performance with a particular focus on the AMD desktop/server platforms.
Keem Bay, Intel's third-generation Movidius VPU (Vision Processing Unit), continues seeing more upstream open-source hardware support within the Linux kernel. Coming to the Linux 5.12 kernel in a couple months will be more support within the crypto subsystem...
Following RadeonSI seeing optimizations around AMD Smart Access Memory (Resizable BAR) support last month, the Radeon Vulkan driver "RADV" within Mesa 21.0 is also seeing similar treatment...
Another one of the features you won't find in the Linux 5.11 kernel is support for the recently ratified NVMe Simple Copy but work on supporting that feature continues...
The Ardour open-source, cross-platform digital audio workstation rung in 2021 by mainlining support for using Intel/AMD FMA functionality for greater performance...
There's nothing quite like some fun holiday-weekend reading as a fiery mailing list post by Linus Torvalds. The Linux creator is out with one of his classical messages, which this time is arguing over the importance of ECC memory and his opinion on how Intel's "bad policies" and market segmentation have made ECC memory less widespread...
Dav1d 0.8 was released this weekend (and subsequently 0.8.1 too) as the latest major release for this CPU-based AV1 decoder hosted by the VideoLAN project. Dav1d continues to be about offering the best AV1 decode speed and with the v0.8 series are even faster results -- so here are some of our initial data points as well from some weekend benchmarking...
In ending out a strong year for OpenBenchmarking.org growth in 2020, there were also many test profile updates and some new test profiles (benchmarks) that were made available in December for Phoronix Test Suite / OpenBenchmarking.org users...
The numbers Steam posted on New Year's Day for the December 2020 Linux gaming marketshare showed a drop of 0.33% down to just 0.57%. That is a rather large drop but now Valve has updated their numbers and point to Linux still regressing percentage wise but not as bad as originally reported...

New Year's Eve two years ago I wrote about the open-source / Linux letdowns of 2018. It was well received at the time and sparked some interesting discussions so as we celebrate the start of 2021 I figured it would be interesting to look back and see which of those letdowns were since resolved and what ones are remaining...
2020 was easily the best year yet for Mesa with this collection of open-source OpenGL/Vulkan drivers seeing timely new hardware support, Intel's OpenGL support defaulting to Iris Gallium3D, the Radeon Vulkan (RADV) driver adding and defaulting to the ACO compiler back-end, many performance optimizations throughout, timely new GPU hardware support, and a lot more!..
The Panfrost open-source Gallium3D driver matured into good shape over the course of 2020 with providing OpenGL support for Arm Mali graphics hardware. As we enter 2021 it will be interesting to see this year if any "Panfrost Vulkan" driver materializes for open-source Vulkan support on the newer Mali graphics hardware. But at least one area making interesting process is in regards to OpenCL compute support...
