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.

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.

The fourth weekly release candidate of Wine 3.0 is now available for testing...

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...

The KDE-aligned Krita digital painting software has published a retrospective of 2017 and a look ahead to 2018...

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...

Not only is Vega now Vulkan 1.0 conformant with RADV, but it's also much faster if pulling down the very latest Mesa bits...

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...

Git 2.16-rc0 has been released as the first test version of this upcoming distributed revision control system update...

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...
