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...

This past week Intel published an Intel Core Ultra 200S Series "Arrow Lake" performance status update following mixed reviews since launch around the Arrow Lake gaming performance that were inconsistent with Intel's internal findings. Among Intel's findings detailed in their report this past week were some new BIOS performance optimizations, some misconfigured performance settings in early/reviewer BIOSes, and also some Windows 11 updates being pushed down to help with different performance issues. ASUS already started releasing new BIOSes that incorporate the 0x114 Arrow Lake intended to help the situation. While it's been a Windows-focused issue, I couldn't help but to run Intel Arrow Lake performance comparison benchmarks on Linux with the new microcode / BIOS.
