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...

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...

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.

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...

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...

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...

Well known AMD Mesa developer Marek Olšák landed more than two dozen patches this weekend fixing up Next-Gen Geometry (NGG) Stream-Out / Transform Feedback functionality for RDNA/RDNA2 GPUs ahead of the NGG Stream-Out enabling for upcoming RDNA3 graphics cards...

Last month I wrote about a new set of Linux patches that provide for better power management on AMX-enabled "Sapphire Rapids" servers. The patches help ensure AMX-enabled CPUs can reach their lower power states for maximum power-savings and that also helps ensure other CPU cores have a larger thermal/power budget for hitting their rated turbo frequencies. That change/fix will be coming in the Linux 5.20 cycle later this summer...

José Expósito continues with recently stepping up to manage libinput releases, the input handling library that for the modern Linux desktop is now widely used across both X.Org and Wayland environments. Libinput 1.21 debuted this weekend with various improvements over the prior release...

One of the many changes with the recent Ubuntu 22.04 LTS release was enabling systemd-oomd by default as the out-of-memory daemon that can kill processes when under memory pressure. Unfortunately, for some users this has led to a poor desktop experience with finding their applications being unexpectedly killed. Ubuntu developers are now discussing how to improve this OOMD handling...

PipeWire 0.3.52 was released today as the newest version of this open-source server for handling audio/video streams on the Linux desktop and increasingly being used now as a replacement for PulseAudio...

There was much interest in the recent Python 3.11 beta benchmarks showing much performance uplift from this in-development version of Python compared to prior 3.x releases. While Python 3.11 performance is looking great and huge advantages compared to prior versions, there are also alternative Python implementations like PyPy and Pyston. Stemming from Phoronix reader requests, here are benchmarks showing how Python 3.11 beta performance compares to those alternative Python implementations.

Variable rate refresh (VRR / FreeSync / Adaptive-Sync) support for GNOME's Mutter compositor is closer to being merged. The native back-end support for VRR that has been in development the past two years is no longer considered a work-in-progress and it's believed there are no longer any blocking issues that would prevent this code from landing...

The real-time (RT) patch series still hasn't been mainlined but the patch delta is slowly winding down with each new kernel version. Out today is the re-based RT patch series for the recently minted Linux 5.19-rc1 with some of the prior real-time patches having been upstreamed this merge window and other patches re-based to work with the newest kernel code...

Last month RHEL 9.0 reached GA as the newest major update to Red Hat Enterprise Linux. Since then I've been trying out RHEL 9.0 on a few servers. To little surprise, especially for latest-generation Intel Xeon Scalable and AMD EPYC servers, RHEL 9.0 is offering significant uplift compared to the existing RHEL8 series. Here are some Red Hat Enterprise Linux 9.0 benchmarks comparing the performance to RHEL 8.6.

In kicking off SUSECON, SUSE has announced the release of SUSE Linux Enterprise 15 Service Pack 4. Notable with SLE 15 SP4, SUSE is already switching to using NVIDIA's open-source GPU kernel-mode driver that NVIDIA open-sourced last month and is under active development and has a long road ahead before it's even feasible for upstreaming into the mainline kernel...
