seL4 Micro-Kernel Working Towards A General-Purpose, Multi-Server OS

The seL4 micro-kernel that has been in development for over a decade saw the creation of the seL4 Foundation last year to further the project's goals. In 2020 the seL4 micro-kernel also added RISC-V as one of its primary CPU architectures.

The seL4 micro-kernel and its ecosystem continue on an upward trajectory even with everything going on in the world and competition from other open-source kernels. Today during the FOSDEM Online 2021 event there was

KDE Plasma 5.22 Will Support Direct Scan-Out For Full-Screen Games / Apps

While Plasma 5.21 isn't even out for a few more days, there is now a big reason to look forward to KDE's Plasma 5.22 release later in the year: KWin finally supports direct scan-out for full-screen games/apps!

The KDE KWin compositor with Plasma 5.22 will finally support direct scan-out for full-screen software, namely games. This direct scan-out is about avoiding an unnecessary copy of the screen contents by the compositor

FOSDEM Online 2021 Is Happening This Weekend

FOSDEM, the Free Open-Source Developer Europeans' Meeting, remains one of the top open-source/Linux events in my book. Each February for this long tenured event thousands of open-source/Linux enthusiasts would gather in Brussels, Belgium for many technical and interesting talks on a wide range of subjects. Unfortunately due to the COVID-19 pandemic, FOSDEM can only take place virtually this year but that does allow for broader participation and you can enjoy all of the content online this weekend.

LLVM Lands Support For OpenMP Offloading To AMD Radeon GPUs

While the AMDGPU back-end has been part of mainline LLVM for years, not until now has it supported an OpenMP toolchain for offloading to Radeon GPUs.

The AMD work for allowing an OpenMP offloading toolchain for the AMDGPU back-end has been merged this week. Ultimately this is for allowing OpenMP code to be offloaded to Radeon GPUs for compute,

AMD has been maintaining AOMP as their downstream of LLVM Clang for supporting OpenMP offloading to Radeon hardware. But exciting is this merge request after one month of review now being mainlined

GNU Network Utilities Sees First Major Release In 9 Years (inetutils 2.0)

The GNU Network Utilities (inetutils) has seen its first major release in nine years or even the first release at all in six years since the prior point release. With GNU inetutils 2.0 are several updates to common programs like ping and ifconfig.

GNU's inetutils provides the commonly used command-line network utilities on Linux and other Unix-like systems. Given the significant time since the inetutils 1.9 release in 2011, there are a number of changes to find with today's

Zink Can Now Run On Lavapipe But You Really Want To Avoid It

In addition to this week seeing Zink now running on NVIDIA's proprietary driver for supporting this Gallium3D-based OpenGL over Vulkan implementation, it can now run on top of Lavapipe as the CPU-based Vulkan implementation. But for end-users that is really something you would want to avoid.

With the newest Mesa 21.1-devel code as of today, there is support for running Zink on Lavapipe. Lavapipe is the software Vulkan implementation merged last year to Mesa as a CPU-based Vulkan

After A Bumpy Cycle, AMD Performance Will Shine Brighter On Linux 5.11

For those following the saga of the AMD frequency invariance regression on Linux 5.11 since the Christmas investigative benchmarking looking at the performance regressions , everything now looks like it will be buttoned up in time for the Linux 5.11 stable release. As noted yesterday, there was a curve ball this week in that the patch proposed by SUSE's Giovanni Gherdovich in January to address the frequency invariance regression was turned down by the Linux power management maintainer and instead he (Rafael Wysocki of Intel) proposed an alternative


Fedora 34 Will See HarfBuzz-Enabled FreeType As The Latest For This Huge Feature Release

The plan for Fedora 34 to improve font rendering by enabling HarfBuzz in FreeType was approved this week by the Fedora Engineering and Steering Committee.

Fedora 34 is now set to enable the HarfBuzz text shaping engine within the FreeType font rasterization engine. The net gain is improved hinting of glyphs particularly for languages with complicated text shaping like where glyphs are composed from multiple characters.

FreeType has supported HarfBuzz for more than a half-decade and Fedora enabling it with its FreeType packaging will allow for some bugs to finally be addressed.

Intel On Their 11th Gen H35 Processors: "Fastest Single-Threaded Laptop Performance"

Intel sent out a news release on Thursday proclaiming their new 11th Gen H35 "Tiger Lake H" processors deliver the "fastest single-threaded laptop performance" thanks to the Core i7 11375H delivering up to 5GHz turbo frequencies.

Intel's news release compares the new Core i7 11375H Tiger Lake processor against their existing parts and then the now-prior generation AMD Ryzen 4800HS / 4900H parts.
