Phoronix

Last week with the release of Blender 3.2 bringing AMD HIP support for Linux to provide for Radeon GPU acceleration, I posted some initial benchmarks of AMD Radeon RX 6000 series with HIP against NVIDIA RTX with OptiX. There was interest by some Phoronix readers in also seeing NVIDIA CUDA results even though OptiX is in good shape with RTX GPUs, so with that here are results of NVIDIA CUDA vs. NVIDIA OptiX vs. AMD HIP with Blender 3.2 on Ubuntu Linux.

KDE Plasma 5.25 is now shipping as the latest half-year major update to the KDE desktop...

Earlier this year Wine began experimenting with GitLab to improve their development workflow for this open-source project that allows Windows games and applications to run on Linux. It's now been decided that the GitLab workflow is useful and will now be their path forward...

While there are many exciting new features coming with Linux 5.19, one of the features that wasn't submitted this cycle unfortunately was the Multi-Gen "MGLRU" code led by Google. As covered in several prior Phoronix articles, the MGLRU support has exciting performance implications for making the Linux kernel's page reclaim code far more efficient...

Approved by the Fedora Engineering and Steering Committee this week is returning Fedora Cloud base to be listed as an official Fedora edition...

Oracle on Monday released the Oracle Linux 9 Developer Preview as their take on Red Hat Enterprise Linux 9 that reached general availability last month...

For those interested in open-source CAD solutions, FreeCAD 0.20 is out today as the newest version of this general purpose 3D computer-aided design modeler that has been in development now for nearly twenty years...

One of my personal gripes with AMD's Zen CPU support on Linux has been the lack of timely support for CPU temperature monitoring with their "k10temp" driver. Even though usually just new IDs are often needed and sometimes needing to adjust offsets or other minor changes, it has traditionally been done post-launch and sometimes left up to patches from the open-source community. Thankfully that has been changing and with Zen 4 it looks like that support will be ready for launch-day with the mainline Linux kernel...

To organize efforts around improving Fedora Linux for heterogeneous computing, a new special interest group "SIG" is looking to be established to help ensure the success of Fedora in the world of XPUs, the growing and very diverse software ecosystem around accelerators, etc...

While not record-shattering like the 1.1 Exaflops Frontier supercomputer at ORNL that took the Top500 spot this year from Fugaku, LUMI was inaugurated today with the claim of Europe's most powerful supercomputer...

AMD's Radeon Memory Visualizer "RMV" tool from their GPUOpen initiative has allowed better understanding video memory usage with Windows across multiple APIs. In citing the "rising popularity of gaming on the Linux OS", AMD has now enabled Linux support for this tool...

After battling Ceph storage issues and related problems for the past day after two solid-state drives failed, the FreeDesktop.org GitLab that is used for the centralized, coordination of the open-source Linux graphics driver development and other open-source software is back online...

A patch from AMD to further tune the Linux kernel's scheduler around NUMA imbalancing has been queued up and slated for introduction in Linux 5.20. For some workloads this scheduler tuning can help out significantly for AMD Zen-based systems and even on Intel Xeon servers has the possibility of helping too...

GNOME developers are working on supporting the Linux KMS "Max BPC" connector property that is supported by some of the Direct Rendering Manager drivers for limiting the maximum bits per color permitted. In turn properly supporting this setting can take care of monitor issues seen on some systems where the monitor may randomly flicker or have other issues unless otherwise lowering the refresh rate or resolution...

EROFS-Utils 1.5 has been released as the set of user-space utilities for the EROFS Linux read-only file-system that is increasingly popular with Android/embedded use-cases and growing container usage...

Earlier this month marked the launch of the HP Dev One as an interesting collaboration between HP and System76 for a laptop optimized for Linux developers and running System76's Ubuntu-based Pop!_OS operating system. It's a very interesting laptop and well thought out for Linux use with an AMD Ryzen 7 PRO 5850U SoC and integrated Radeon graphics for satisfying the preferences of many Linux developers preferring a fully open-source driver stack. Thanks to the large scale manufacturing of HP, it's also a competitively-priced Linux laptop compared to many of the Linux laptops from smaller vendors that are based on Clevo or other white box laptop designs.

Linus Torvalds just released Linux 5.19-rc2 with the fixes that have trickled in for this week past the closure of the Linux 5.19 merge window...

Centralized development around Mesa, the X.Org Server, and dozens of other open-source projects is at a stand-still this weekend due to FreeDesktop.org GitLab crashing with the entire service down...

In addition to all of the Linux 5.19 feature changes, sent in today for the Linux 5.19-rc2 release later today were some additional x86 platform driver updates. Sent in as part of the "fixes" for the week were some new device IDs adding in some new hardware support to existing drivers...

Introduced in the early 80's for the Motorola 68000 series was Versa Module Eurocard "VMEbus" standard that continues to see industrial uses. While still seeing some reported use today, unfortunately the same cannot be said for the quality of the VMEbus Linux support. After the VME subsystem was promoted out of staging a decade ago, the VME hardware drivers failed to ever leave staging and the code has fallen into disrepair and no maintenance now for the past half-decade. So the VME subsystem support is preparing to depart back to the land of the kernel's staging area...
