When it comes to ARM-powered workstation boards there hasn't been a whole lot to get excited about with the likes of the Socionext 96Boards Developerbox being quite expensive and not yielding good performance or featureful boards compared to alternative Intel/AMD/POWER workstation/enthusiast boards. One of the more promising ARM workstation boards we have been following is the HoneyComb LX2K (formerly the "ClearFog" board) and it's looking like it could end up being a decent offering in this space...

A kernel patch from CodeWeavers is landing in the Linux 5.4 kernel and will help some 64-bit Windows games run nicely under Wine (and the likes of CrossOver / Valve's Proton) with newer Intel and AMD systems...

Hot off last night's Linux 5.3 release, the GNU folks have this morning released GNU Linux-libre 5.3-gnu as their downstream flavor of the kernel that strips out support for loading proprietary kernel modules and the ability to load binary-only microcode/firmware files, among other steps for aiming at a pure free software kernel...

One of the areas the RadeonSI OpenGL and RADV/AMDVLK Vulkan drivers have had a challenging time promptly support with AMD Navi GPUs has been the NGG (Next-Gen Geometry) functionality but it's slowly getting worked out...

Last month I did some fresh benchmarks of Intel's new open-source OpenGL Linux driver with Mesa 19.2 and those results were looking good as tested with a Core i9 9900K. Since then, more Intel Gallium3D driver improvements have landed for what will become Mesa 19.3 next quarter. In taking another look at their former/current and new OpenGL drivers, here are fresh benchmarks of the latest code using a Core i7 8700K desktop as well as a Core i7 8550U Dell XPS laptop.

The Linux 5.3 kernel is expected to be released as stable today and that will mark the opening of the two-week Linux 5.4 merge window. Here is a look ahead at some of the material expected to make it into this next version of the Linux kernel that will also be the last major stable release of 2019...

KDE's annual Akademy developer conference took place this past week in Milan, Italy. But even with that in-person event the development of the KDE desktop environment didn't let up in landing new improvements...

Currently the Mesa OpenGL/Vulkan drivers have relied upon matching executable names for applying game/application-specific workarounds. But with Vulkan as part of the instance creation information and VkApplicationInfo it's possible to optionally advertise the rendering engine and version in use. The Mesa Vulkan drivers are now making use of that information to allow for more uniform workarounds...

While the Linux kernel is well known for not offering a stable API/ABI, Google and other enterprise Linux distribution vendors tend to aim at providing their own stable ABI for the lifespan of their products. Google engineers talked in Portugal this week at Linux Plumbers Conference 2019 about some of their means to maintaining a stable API/ABI for Android's Linux kernel...

If you are running the likes of the Raptor Blackbird for a POWER open-source desktop and wanting to run Fedora on it, currently you need to use the Fedora "server" CLI installer and from there install the desired packages for a desktop. But moving forward, Fedora is beginning to spin Workstation and Live images for PPC64LE...

One of the steps Intel's open-source developers continue working on for Linux is supporting "execute only memory" that will already work with some of today's processors and serve as another defense for bettering the security of systems particularly in a virtualized environment...

While the upcoming Linux 5.4 kernel cycle is finally bringing a driver for Microsoft exFAT file-system read/write support, it's dated on an old Samsung code drop that has seen little public work over the years. Since queued for staging-next, there has been a big uptick in clean-ups and other activity, but there also exists another alternative out-of-tree exFAT Linux driver...

With the upcoming LLVM Clang 9.0 compiler release there is an amazing achievement more than a decade in the making... The mainline Clang compiler can finally build the mainline Linux x86_64 kernel. The AArch64 state has been in better shape in recent years with multiple Arm vendors using Clang as their default compiler including to build the Linux kernel, but finally in 2019 the mainline Clang can build mainline Linux x86_64. There are a few caveats, but in this article is my experience in doing so with LLVM Clang and the Linux 5.3 kernel as well as running some preliminary benchmarks on AMD and Intel hardware.
