The Fedora Engineering and Steering Committee (FESCo) has approved a fresh batch of features for the next Fedora Linux distribution release...

For those not yet on the GCC 11 or GCC 12 stable series, GCC 10.4 is out today as the latest in that older stable series...

With last week seeing AMDVLK 2022.Q2.3 released as an update to AMD's official open-source Vulkan Linux driver and it noting performance improvements, it was time for some fresh benchmarks of that driver up against Mesa's alternative "RADV" Vulkan driver. Here are some fresh benchmarks with an AMD RDNA2 GPU for seeing how RADV continues competing -- and usually outperforming -- AMD's own official open-source driver.

A "sched/fair" scheduler change queued this morning into TIP's sched/core for Linux 5.20 aims to enhance the efficiency when searching for an idle CPU under heavy system load. The change led by Intel should improve the kernel's efficiency when the system is overloaded but as with most low-level tuning does run the risk of regressions...

A decade after Luc Verhaegen started the Lima driver effort for reverse-engineering Arm Mali graphics, developers continue occasionally working on improvements to this Gallium3D driver for older generations of Mali hardware. The most recent feature work is finally enabling 4x MSAA support...

Last month for their Vision conference, Intel announced the Habana Labs Gaudi2 accelerator. Gaudi2 is the second-generation offering from Intel-owned Habana Labs for training and inference. The open-source Linux kernel driver support for Gaudi2 is now getting underway along with accompanying open-source user-space software stack support...

Git 2.37 is out today as the latest feature update to this widely-used, distributed revision control system...

The Rust-GCC front-end that allows Rust code to be compiled with the GNU Compiler Collection (GCC) could possibly be upstreamed for next year's GCC 13 compiler release but not necessarily complete at that stage. In any case, it's good seeing progress on Rust-GCC as an alternative to Rust's official LLVM-based compiler...

Merged today to Mesa 22.2 was a four month old merge request for the open-source Radeon Vulkan driver "RADV" that significantly improves the 16-bit FidelityFX Super Resolution (FSR) performance...

One of Intel's many wonderful open-source projects for creators is OSPRay Studio that is their interactive visualization and ray-tracing application built atop their OSPRay portable ray-tracing engine. OSPRay Studio has been making steady progress since its 2020 debut and out today is their newest update...

The Firefox 102.0 release is now available for download ahead of its stable release announcement tomorrow...

Coming about last week was a Fedora 37 change proposal to improve the profiling and debugging of Fedora packages but with possible performance costs. That suggested change is about adding "-fno-omit-frame-pointer" to the default CFLAGS/CXXFLAGS when building packages so the frame pointer is always available for improving the debugging/profiling of the stock Fedora packages. Unfortunately, it can come with significant performance costs as these benchmarks show.

Google engineers are working on the notion of "memory modes" for the Flash-Friendly File-System (F2FS) with the intent on introducing a "low memory" mode for storage devices that would alter its behavior. Presumably Google is working on this new F2FS feature for low-end Android devices...

Linus Torvalds just released Linux 5.19-rc4 as the newest weekly test candidate. There are more patches this week than in the prior Linux 5.19-rc versions but nothing too scary as well as having some notable patches in tow...

Jens Axboe, Linux storage expert and IO_uring lead developer, released liburing 2.2 this weekend as the newest version of this helper library that makes it easier for user-space software to make use of the Linux kernel's IO_uring support...

NVIDIA has contributed support to the FFmpeg multimedia library for being able to take advantage of AV1 GPU-accelerated video decoding by way of the VDPAU API when using the latest-generation NVIDIA RTX 30 "Ampere" GPUs...

Last month Microsoft issued the first production release of CBL-Mariner 2.0, its in-house Linux distribution used for powering services from Microsoft Azure to WSL use-cases and more. CBL-Mariner 2.0 this weekend saw a rather large monthly update with a number of fixes, package updates, and new additions to this "Common Base Linux" platform...

Shotcut remains one of the leading open-source, cross-platform video editors built atop the MLT Multimedia Framework with FFmpeg. Out this week is Shotcut 22.06 as the newest feature update to this non-linear video editing solution...

For the Fedora 37 cycle Fedora CoreOS is hoping to be promoted to an official release "edition" alongside the likes of Fedora Workstation and Fedora Server...

2022 is certainly looking to be interesting on the open-source graphics driver front... You probably didn't have Imagination publishing an open-source PowerVR Vulkan driver on your 2022 bingo card nor NVIDIA working on an open-source GPU kernel driver. The latest 2022 surprise is the OpenChrome driver project is hoping to finally be mainlined in Linux 5.20 for open-source VIA graphics for those still running vintage VIA x86 hardware...
