The holiday between Christmas and New Year's is... Linus Torvalds' birthday on 28 December. Capping off the Linux creator's 55th birthday week is the Linux 6.13-rc5 kernel release...

Last weekend a Meta engineer posted Linux kernel patches to make use of the AMD INVLPGB instruction for broadcast TLB invalidation. The Linux kernel can in turn invalidate TLB entries on remote CPUs without needing to send IPIs and without having to wait for remote CPUs to handle those interrupts. Synthetic benchmarks shown in that patch series were very promising and thus I carried out some benchmarking over the holidays of this AMD INVLPGB support for the Linux kernel.

Back in April was the release of the Amarok 3.0 music player for KDE after a six year hiatus and their first version ported to using the Qt5 toolkit and KDE Frameworks 5. Now in ending out 2024, the Amarok team has released an updated version of this open-source music player that provides initial support for the Qt6 toolkit and KDE Frameworks 6...

Thanks to work from Intel engineers, the upcoming Linux 6.14 kernel cycle will feature faster USB xHCI DbC performance for debug performance and a few other missing xHCI bits being addressed. Plus there is a fix for a rare 10 year old USB bug report...

From my independent monitoring, Ubuntu Linux had a pretty great year. Ubuntu 24.04 LTS shipped and has been well received across enterprises, Canonical engineers have been focusing more on performance optimizations for Ubuntu, and there has been other interesting changes like their new commitment to always ship the latest upstream Linux kernel version as of Ubuntu release time. Plus they have continued with various GNOME desktop improvements, Ubuntu on servers continues with steady traction, and all-around was a pretty exciting year for the Ubuntu camp...

Earlier this month the Fish Shell 4.0 went into beta with the C++ code ported to Rust. Now with most of the Fish Shell code transitioned to Rust, the project put out a blog post this weekend outlining the successes and challenges they have encountered in porting their large C++ codebase to Rust...

While Linux 6.13 is introducing basic support for various Apple iPads and iPhones using A-series SoCs, the support is just that: basic. Various feature limitations remain for those dreaming over the prospects of running Linux on older Apple mobile devices. One of various feature limitations remaining are around backlight control for different models and for that there is the Apple DWI backlight driver for Linux that continues to be hacked on...

The x86 fixes pull request was sent out this morning ahead of the Linux 6.13-rc5 kernel being released later today. Both x86 fixes this week pertain to Intel bits: a self-test issue on upcoming Intel FRED (Flexible Return and Event Delivery) systems and also an issue of Intel TDX confidential computing VM guests potentially leaking decrypted memory within the unrecoverable error handling...

This year NVIDIA's official Linux graphics driver enjoyed much more robust Wayland support, their open-source kernel modules have matured greatly and are now being used by default, and their proprietary Vulkan and OpenGL drivers remain in good standing for performant Linux gaming and workstation graphics. NVIDIA's Linux driver stack had a rather great year...

The Fedora Linux distribution had another great year with the successful releases of Fedora 40 and Fedora 41 that were both rather polished and largely on-time -- something that couldn't be said frequently of Fedora releases long ago. Fedora Linux has continued pushing leading edge innovations into their distribution thanks to the sponsorship and upstream contributions of Red Hat engineers. 2024 was a rather successful year for this high grade Linux distribution...

Following the benchmarks earlier this month looking at the Red Hat Enterprise Linux 10 beta performance as well as the AlmaLinux 10 beta, on the same AMD EPYC server here are benchmarks when adding in CentOS Stream 10 to the mix. CentOS Stream 10 as the upstream to Red Hat Enterprise Linux 10 is largely similar to what's found in the RHEL 10.0 beta but one of the key differences is being powered by Linux 6.12 LTS rather than Linux 6.11 as currently used by the AlmaLinux/RHEL 10 beta. Here is how the performance of CentOS Stream 10 is looking in comparison on the same hardware.

AMD's new products this year have not only been supported well on the server side with their new EPYC 9005 "Turin" processors but also on the consumer side with the Ryzen AI 300 series laptop and Ryzen 9000 series desktop Zen 5 processors. AMD provided timely Zen 5 support across the stack as well as pursuing new AMD P-State driver optimizations, getting out the AMDXDNA Ryzen AI accelerator driver, and a lot of other new open-source Linux code for new hardware features, prepping for upcoming hardware like RDNA4 graphics, and pursuing optimizations for existing hardware...

The GNOME desktop environment had a vibrant 2024 with landing many new features, continuing to refine its (X)Wayland integration, apps like Ptyxis as a modern terminal taking off, and more. From the software side 2024 was great for GNOME while over on the GNOME Foundation side they had to deal with coping from running a recent deficit and also their executive director departing after less than one year...

Linux 6.13 is introducing a new Lazy Preemption mode with the "PREEMPT_LAZY" option. The lazy preemption mode is similar to full preemption but is less eager to preempt normal (SCHED_NORMAL) tasks. The goal is on reducing lock holder preemption and obtaining some of the performance gains found under the voluntary preemption mode. For Linux 6.13 the lazy preemption mode was exposed for x86/x86_64, RISC-V, and later added for LoongArch. Likely with the upcoming Linux 6.14, lazy preempt should work on POWER platforms...

Both GCC and LLVM/Clang made great strides in 2024 in rounding up their latest C and C++ support, enabling new hardware targets, and a variety of other features. Plus other open-source compilers targeting different features / languages, device types, and more also advanced a lot this calendar year. For those excited about turning code into binaries, here's a look back at the most popular compiler articles on Phoronix...

The KDE desktop progress made over the course of 2024 was particularly stand-out thanks to the Plasma 6.0 debut near the beginning of the year and then Plasma 6.1 and 6.2 further stabilizing and polishing this open-source desktop. It was a very fine year for the KDE desktop...

Linux 6.12 was recently promoted to being this year's Long Term Support (LTS) kernel with it being the last major kernel release of 2024. For those enterprise Linux users, hyperscalers, and others typically jumping from one annual LTS kernel to the next, in this holiday article are some benchmarks looking at the performance benefits of Linux 6.12 LTS compared to Linux 6.6 LTS while testing on an AMD Ryzen Threadripper workstation.

In addition to the exciting hardware launches this year particularly around Xeon 6 Granite Rapids, Lunar Lake processors, and the new low-cost Battlemage graphics cards, what remains particularly exciting and consistent are all of Intel's great investments around open-source and Linux. Over 2024 there were many exciting performance optimizations, new Linux kernel features, GCC and LLVM/Clang compiler toolchain improvements, and countless other enhancements made throughout the open-source ecosystem by Intel engineers...

Four years ago already the Raspberry Pi 400 was announced as a Raspberry Pi keyboard computer built around the Raspberry Pi 4, passively-cooled, and all packaged up nicely in a keyboard form factor. Announced earlier this month was the Raspberry Pi 500 as the successor and now built around the Raspberry Pi 5. For $90 USD this keyboard computer is a very versatile and convenient compact Linux PC.
