With LLVM 6.0 being branched this week and that marking the end of feature development on this next compiler update before its stable debut in February, here are some benchmarks of the very latest LLVM Clang 6.0 compiler on AMD's EPYC 7601 32-core / 64-thread processor as we see how well the AMD Zen "znver1" tuning is working out.
Qt 6.0 planning has begun and we should be hearing more about this next major tool-kit update as the year goes on. Here's some of what we can expect from Qt in the near future...
During the recent holidays when running light on benchmarks to run, I was toying around with LLVMpipe in not having run this LLVM-accelerated software rasterizer in some time. I also ran some fresh tests of Intel's OpenSWR OpenGL software rasterizer that has also been living within Mesa...
For those wondering Mesa's rate of change last year while adding in many OpenGL 4.5~4.6 features, a lot of Vulkan driver activity, countless performance optimizations, and the plethora of other work that took place in 2017, here are some numbers...

Aside from our 2017 year-end recap, if you were busy reliving the favorite moments of last year and missed some of our original content in December, here's a look back at the top highlights of last month...
Released nearly one year ago was the experimental NVIDIA VkHLF project as a high-level framework for Vulkan. It's been a while since last hearing anything about it, but some new code was just merged...
Here are some other end-of-year benchmarks I had been working on in looking at the current performance of Mesa 17.2.2 versus 17.3.1 versus 17.4-devel Git with RadeonSI OpenGL on three different graphics cards...
While AMD developers worked on the Radeon Gallium3D "Clover" OpenCL support for some time, that really hasn't been the case in years with the AMD's open-source OpenCL effort these days being focused upon their ROCm compute platform. Some within the community though still work on this OpenCL Gallium3D state tracker from time to time and this New Year's weekend is an interesting project pairing Clover with AMD's proprietary OpenCL compiler...
While Haiku OS is incredibly close to delivering their long-awaited beta, it didn't end up materializing in 2017 but they still made much headway into this open-source BeOS-inspired operating system...
The open-source NVIDIA "Nouveau" driver project providing independent, reverse-engineered 3D graphics driver support for GeForce GPUs made a lot of progress in 2017 although not as great as many would have hoped for. But 2018 will hopefully prove to be more interesting...
As shown in recent benchmarks of the RADV Vulkan driver, while the Radeon RX Vega GPU support is now considered conformant and fully-functioning, it's not yet as well optimized as earlier generations of GPUs with this open-source Radeon Vulkan driver. Fortunately, it looks like Bas Nieuwenhuizen is working on more performance optimizations...
DRM subsystem contributor Noralf Trønnes is proposing a patch-set to provide generic FBDEV emulation support in DRM drivers via exportable dumb buffers...
With the Mesa-based RADV Vulkan driver having just landed a significant performance optimization you may be wondering whether RADV Vulkan now leads to faster gaming frame-rates than using the mature RadeonSI OpenGL driver... I was curious so I ran some fresh benchmarks using the newest Mesa Git code.
With the LLVM Clang 6.0 code branching and feature freeze coming up on 3 January, here's a recap of some of the most interesting new features and changes to find with the LLVM 6.0 compiler infrastructure and Clang 6.0 C/C++ front-end...
Alex Deucher of AMD has sent in the last feature updates to DRM-Next of new AMDGPU material to be queued for the Linux 4.16 kernel cycle that will begin later in January...
Remember Arcan? The Linux display server built off a game engine. The project is ending 2017 with the release of the Arcan 0.5.4 display server and its associated Durden v0.4 desktop...
I would like to wish all Phoronix readers a happy new year and hopeful that 2018 will be even better for Phoronix and all open-source/Linux communities...
Ahead of next week's LLVM 6.0 feature freeze / code branching, the Clang C/C++ compiler front-end has picked up support for the concept of configuration files...
I've been working on some AMD EPYC virtualization tests on and off the past few weeks. For your viewing before ending out the year are some initial VirtualBox vs. Linux KVM benchmarks for seeing how the guest VM performance compares.
Five years ago today I wrote about The Problems Right Now For Gaming On Linux with regards to challenges for Linux gaming when it comes to the software and hardware. In the five years since and with seeing thousands of more games be made available for Linux, the situation still is not ideal but it's much better than at the end of 2012...
2017 was easily the most pivotal year for the Ubuntu Linux distribution in years with Canonical having decided to end Unity 8 development in favor of moving to a GNOME Shell Wayland session. There was also the decision to develop a new server installer that is still under development, Snaps and its underlying tech continues to be worked on as an alternative to Flatpak, and Ubuntu continues to dominate the cloud landscape...
Just hours ago was a new patch series being merged to Mesa Git by RADV co-founder Bas Nieuwenhuizen to allow for correct DCC usage. I have just finished up my initial benchmarks of those RADV changes and they indeed help the few Radeon GPUs tested.
AMD/Radeon had a stellar 2017 for Linux most notably with delivering working Radeon RX Vega open-source driver support at launch, AMDGPU DC finally being merged to the mainline Linux kernel, and the official "AMDVLK" Vulkan driver now being open-source. Besides never-ending performance tuning, there's really just one major feature/area where the Radeon Linux graphics driver support is missing...
Wayland had a very successful year with Ubuntu 17.10 now using it by default, more niche/hobbyist Wayland compositors making progress, KDE Plasma on Wayland becoming more usable for day-to-day use, more applications/libraries natively supporting Wayland, GTK4's Vulkan renderer becoming very usable, and other advancements...
Since October RADV has officially become a Vulkan 1.0 conformant driver for Volcanic Islands GPUs while Sea Islands and Polaris hardware has also been on this same support level. RADV support for the newer Vega GPUs had been lagging behind, but these latest-generation AMD GPUs are now also effectively conformant...
Last week NVIDIA sent out an experimental allocator driver for the Nouveau code-base as well as EXT_external_objects support for Nouveau NVC0 in Mesa. So far though many upstream open-source driver developers are not yet convinced about the current design of this Unix Device Memory Allocation library as a potential replacement to GBM...
The latest in our streak of year-end benchmarking is seeing how Linux performance has evolved over the course of 2017. For that we tested Intel's performance-optimized Clear Linux distribution as well as Ubuntu using releases from the start of the year to their current state for seeing how the performance compares using the same system.
Drew DeVault who is the lead developer of the i3-compatible Sway Wayland compositor has introduced wlroots as a new modular Wayland compositor library...
For those wondering how the LLVM Clang vs. GCC C/C++ compiler performance is comparing as we end out 2017, here are some recent benchmarks using the latest Clang 6.0 SVN and GCC 8.0.0 compilers in a range of benchmarks.
AMD developers working on the newly open-sourced AMDVLK Vulkan driver have pushed out their first post-release code update synced against the latest changes in their internal AMD driver tree...
On the Linux kernel mailing list over the past week has been a discussion about Syzbot, an effort by Google for continuously fuzzing the mainline Linux kernel and its branches with automatic bug reporting...
It's not quite the Ubuntu rolling-release process that some have proposed over the years, but a new proposal is being formulated for shipping updates to key Ubuntu system components on a monthly basis rather than having to wait six months for updates to the Linux kernel, Mesa, etc...
The past few years Siemens has been working on Jailhouse as a Linux-based partitioning hypervisor that has aimed to be a lighter alternative to KVM. It's been seven months since the last update, but now Jailhouse 0.8 is now available...
Support for Memory Protection Keys (a.k.a. PKU / PKEYs) was finished up this year in the Linux kernel, glibc, and related components. This memory protection feature premiered with Intel Xeon Scalable CPUs and is said to be coming to future desktop CPUs, but it doesn't look like that's happening for the Cannonlake or Icelake generations...
