Committed immediately at embargo lift was the mitigation patches for Linux 5.19 Git while the patches have now worked their way back to the maintained stable kernel series. Out this morning is a slew of stable kernel releases back to Linux 4.9 for patching the Intel MMIO Stale Data vulnerabilities that affect many generations of Intel CPUs from Rocket Lake and older...

Mesa's V3DV driver for the Broadcom VideoCore GPU, which is most notably enabling open-source Vulkan API support for the Raspberry Pi 4 and newer, is nearly ready with its Vulkan 1.2 support...

Slow start-up performance of the Firefox web browser has been a frequent complaint on Ubuntu Linux since Canonical shifted over to using the Snap'ed version of Firefox by default. It's certainly what I find most annoying with Ubuntu as well, but at least Canonical engineers continue working on addressing the performance and other awkward issues with the Firefox Snap...

Being worked on since 2020 has been Linux support for user-space peer-to-peer DMA between NVMe drives and yesterday marked the latest iteration of those patches...

Released at the end of May was AlmaLinux 9.0 as the first "community" distribution out of the gates based on Red Hat Enterprise Linux 9.0 that reached GA in mid-May. I've been running AlmaLinux 9.0 on a few Intel and AMD servers to great success. And, yes, as expected the performance matches that of upstream RHEL9.

Besides the Intel OpenCL Runtime / oneAPI Level Zero preparing to make use of that compute engine support, patches merged today to Mesa 22.2 also allow enabling the DG2-class Arc Graphics compute support within the OpenGL/Vulkan drivers...

Earlier this year the folks at firmware consulting firm 3mdeb announced a open-source Coreboot port to a retail Intel Alder Lake motherboard. It's very exciting since outside of Chromebooks, IHV reference boards, and custom server platforms at hyperscalers, it's still rare to find Coreboot support on modern, retail boards. That "Dasharo" open-source firmware effort for the MSI Z690-A WiFi DDR4 has come together nicely over a matter of weeks and the developers are now celebrating their v1.0 release...

Merged earlier this year into Mesa was "Dozen" for Vulkan on Direct3D 12 for use with Microsoft's Windows Subsystem for Linux or in Windows cases where there may be a D3D12 driver installed but no Vulkan support. This is akin to the layering work Microsoft already supports for leveraging Mesa to provide OpenCL and OpenGL atop Direct3D 12. That "Dozen" driver is now readying Vulkan 1.1 support...

Earlier this year Pensando engineers began posting Linux patches for enabling their Elba DPU SoC. This data processing unit is powered by 16 x Arm Cortex-A72 cores and designed for supporting up to dual 200GE networking with this SoC intended for high-end networking equipment. It didn't take long for the AMD integration less than one month after AMD completed its Pensando acquisition with the new Linux patches now reflected as the AMD Pensando Elba...

In addition to the Hertzbleed frequency scaling side-channel attack being made public today as part of "Patch Tuesday" and affecting both Intel and AMD CPUs, Intel is additionally disclosing a set of "MMIO Stale Data" vulnerabilities. The Linux kernel has already been patched for these new vulnerabilities affecting multiple generations of Intel CPUs from Rocket Lake back to Haswell X and Skylake...

Hertzbleed has been made public today as a new family of side-channel attacks making use of frequency side channels. Both Intel and AMD have issued security advisories as a result...

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...

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...

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...

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...

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...
