Now that the Linux 6.9 merge window is past I've begun testing out this in-development kernel on more hardware platforms in the lab. While some performance boosts like Intel Core Ultra "Meteor Lake" running faster on Linux 6.9 was to be expected given EPP tuning in the new kernel specific to those SoCs, one of the unexpected delights has been seeing AMD 4th Gen EPYC performance with some nice performance gains over Linux 6.8 stable.

Fedora 39 had hoped to use the DNF5 package manager by default as the next iteration of this package management solution for RPM-based distributions. But DNF5 wasn't ready and then delayed to Fedora 41 -- skipping over the Fedora 40 series due to the RHEL 10 branching from it and not wanting the very new DNF5 to be part of that merge. Now the change proposal has been re-filed for introducing DNF5 by default in Fedora 41...

Merged on Thursday to GNOME's Mutter compositor is support for the linux-drm-syncobj-v1 Wayland protocol that is used to handle the global migration to explicit synchronization...

CodeWeavers' Elizabeth Figura has been working on the NTSYNC driver to implement Windows NT synchronization primitives for the Linux kernel in order to help the performance of various Windows games running on Linux by the likes of Wine / Valve's Proton (Steam Play). The third iteration of that driver was posted overnight as it seeks to go into the mainline Linux kernel...

Since the mid-90's with the P6 micro-architecture for the Pentium Pro as the sixth-generation x86 microarchitecture, Intel has relied on the "Family 6" CPU ID. From there Intel has just revved the Model number within Family 6 for each new microarchitecture/core. For example, Meteor Lake is Family 6 Model 170 and Emerald Rapids is Family 6 Model 207. This CPU ID identification is used within the Linux kernel and other operating systems for identifying CPU generations for correct handling, etc. But Intel Linux engineers today disclosed that Family 6 is coming to an end "soon-ish"...

Given the recent change by Redis to adopt dual source-available licensing for all their releases moving forward (Redis Source Available License v2 and Server Side Public License v1), the Linux Foundation announced today their fork of Redis...

While the uutils Rust-written Coreutils effort has been chugging along, the upstream GNU Coreutils effort is showing no signs of slowing down. Out today is GNU Coreutils 9.5 with yet more feature work and bug fixes including a security fix for a chmod issue that's been around since the beginning...

While Intel Core Ultra "Meteor Lake" has been working out well under Linux already -- especially with regards to the enticing integrated Arc Graphics -- with the in-development Linux 6.9 kernel it's looking even better for the CPU performance. Here are some initial benchmarks looking at the Intel Core Ultra 7 155H Meteor Lake performance with Linux 6.8 vs. 6.9 Git.

Open-source developer Tomeu Vizoso recently began the effort of creating an open-source, reverse-engineered driver for the Rockchip NPU found in some of the latest Rockchip SoCs. After succeeding at open-source NPU driver support for the VeriSilicon NPU IP, Vizoso took up the challenge of working on Rockchip NPU support. With his open-source user-space driver he's already got his first model running. Not only is it running but it's doing so at similar performance to the proprietary driver...

Some time ago I ran through a number of benchmarks of Google Cloud's C3D VMs powered by AMD EPYC Genoa processors. The AMD EPYC 9004 series showed terrific performance with strong generational improvements over the Intel Xeon Scalable processors. Following that a request came in to examine the PingCAP TiDB database performance given its growing popularity. In this article we'll review those benchmarks showing how GCE C3D delivers strong performance advantages for TiDB.

Samba 4.20 is out as the newest feature update to this free software implementation for SMB networking protocol support and others to enhance file/print interoperability with Microsoft Windows systems...

Besides its desktop-level customizations, further differentiating System76's Pop!_OS Linux distribution from its Ubuntu LTS package base is the tendency to roll down newer versions of the upstream Linux kernel once validated across System76's portfolio of laptops and desktops. The latest on that front is Pop!_OS now shipping with the fresh Linux 6.8 stable series...

Following several days of discussions from both sides of the table over whether SDL 3.0 should revert its Wayland over X11 preference in light of some aspects of the Wayland ecosystem support not being in good shape, for now at least SDL 3.0 is sticking to the Wayland support by default. It may be revisited though closer to release to see how the upstream support is for users of this hardware/software abstraction library widely used by cross-platform games...

Ubuntu maker Canonical has spent the past several months exploring Ubuntu x86-64-v3 based images for leveraging the x86_64 micro-architecture feature level capabilities to target the level embracing AVX/AVX2, FMA, BMI2, and other instructions supported largely since Intel Haswell and AMD Excavator era processors. As shown in benchmarks Ubuntu x86-64-v3 builds can deliver better performance for the AMD/Intel systems of the past number of years. Canonical's latest foray in this area is offering up Microsoft Azure images that are tailored for x86-64-v3...

Blender has long enjoyed faster CPU rendering under Linux compared to using Microsoft Windows. Across many different processors over the years consistently we see faster Linux CPU render performance than under Windows, though that's typically the case for most renderers. With yesterday's release of Blender 4.1, there is even faster Linux CPU render speeds. Here are some initial Blender 4.0 vs. 4.1 benchmarks...

With the SPIR-V and OpenCL support in turn this means Java can run not only on GPUs but also some FPGAs and other devices...

Meta's Yann Collet just released Zstd 1.5.6 as the newest version of this Zstandard compression implementation.

The open-source Panthor DRM driver for supporting newer Arm Mali GPUs was queued in drm-misc-next at the start of March ahead of the Linux 6.9 merge window. It ultimately though didn't see a drm-misc-next pull to DRM-Next ahead of the Linux 6.9 merge window and thus being held off until the Linux 6.10 cycle. This week though that drm-misc-next submission to DRM-Next took place as that driver and other changes begin queuing for Linux 6.10...

Now that Linux 6.9-rc1 was released on Sunday to mark the end of the merge window, here is a look at all of the new features that have been merged for the Linux 6.9 kernel cycle.

Ubuntu Long-Term Support (LTS) releases have been support for 10 years of updates by Canonical while now that has been extended to 12 years but only for Ubuntu Pro customers going for their legacy support add-on. This 12 year support is extended retroactively going back to Ubuntu 14.04 LTS...

The latest upstream development code for the Inkscape vector graphics program has transitioned to using the GTK4 toolkit...

The Linux 6.9 kernel will be able to boot systems with large amounts of memory -- and in particular making use of HugeTLB pages -- much faster than with previous kernels, netting a noticeable reduction in boot times...

AMD open-source Linux driver patches posted last summer enabled the new "VPE" IP block as a general purpose copy engine for future AMD GPUs. This VPE block might premiere in the upcoming AMD RDNA3.5 refresh (RDNA3+) integrated graphics but in any event AMD is already working on the incrementally improved VPE 1.1 IP with that now being supported by the Mesa 24.1 RadeonSI driver code...

It was just last week that Tiny Corp put their AMD Radeon graphics powered compute boxes "on hold" after being frustrated with the lack of select firmware source code and ultimately hitting various bugs. This wasn't the first time they had put their AMD Radeon graphics plans on-hold or dismissed it outright. With the start of the new week now comes plans to re-introduce an AMD Radeon graphics option for their compute boxes alongside their recently announced NVIDIA GeForce RTX 4090 compute rigs...

Intel today published a new version of its NPU Linux driver user-space components that goes along with their iVPU accelerator kernel driver for enabling the Neural Processing Unit (NPU) found within their latest Meteor Lake systems...
