As anticipated the Linux 6.13 kernel was promoted to stable today with an on-time release and in turn also marking the start of the Linux 6.14 merge window. Linux 6.13 stable has plenty of fine features for this first major kernel release of 2025.

The pid_max tunable for the maximum number of process IDs allowed simultaneously was increased by default back in 2019 with systemd. But that increase breaks a long held assumption by some user-space software that pid_max or the process ID would not be greater than 65,535. To now better workaround such outdated user-space software, a set of patches for the Linux 6.14 kernel will allow adjusting the pid_max limit on a per PID namespace basis to help cope with such software hitting such artificial limits and without having to lower the overall system limit.

Ahead of the Linux 6.13 stable kernel expected to be released later today, there is a last minute fix for the EEVDF CPU scheduler.

Following the release a few days ago of GNU Coreutils 9.6, the Rust Coreutils "uutils" project as a re-implementation of these core utilities within the Rust programming language is out with a fresh update.

Linux kernel graphics drivers have been growing too much in size that they are taking too long to load at boot time for quickly lighting up the display to present the nice Plymouth boot splash experience. This has led to situations of the Plymouth boot splash screen falling back to its simple text-based interface after timing out. As a workaround, Fedora 42 is looking to use the generic "SimpleDRM" driver during this initial boot splash screen experience to initially avoid the bulky DRM drivers.

Red Hat engineer Hans de Goede wrote a blog post a few days ago around the Intel IPU6 and newer web camera support still being a challenge on Linux. While various Intel IPU6 open-source code has been upstreamed, there remain differences with a number of laptops currently available still not working out-of-the-box for web camera support on Linux. Hans de Goede has now initiated a change proposal for Fedora 42 to take care of more Intel web camera issues.

Yesterday I looked at how the Intel OpenCL GPU compute performance evolved for the Arc Graphics B580 in the one month since that first Battlemage graphics card premiered. There were nice Intel GPU compute optimizations merged over the past month to improve the experience. Here are some Linux graphics/gaming benchmarks for the Intel Arc B580 comparing the prior launch day Linux driver performance to where the Mesa performance is at now.

The modern GNOME desktop hasn't had a core application to playback audio files although many different audio/multimedia players exist. But now for the upcoming GNOME 48 desktop release, there is now a promoted core app for audio playback: Decibels.

ARM64 ILP32 is the Armv8 architecture with a 32-bit ABI rather than 64-bit -- akin to the "x32" x86 effort that never really took off on Linux. ARM64 ILP32 support never ended up making it into the mainline Linux kernel or GNU C Library but did appear within the GNU Compiler Collection. But years later and little use, GCC developers are consider deprecating ILP32 support ahead of its eventual removal.

Back in 2022 there were Linux kernel developers like Linux's second-in-command Greg Kroah-Hartman recommending that Intel Alder Lake laptops be avoided. This was due to the Intel web camera support in those new-at-the-time laptops yet to be properly upstreamed and relying on binary bits. Over time that Intel IPU6 MIPI camera support has seen portions of the code upstreamed into the mainline Linux kernel and distributions like Fedora taking extra steps to make them work but still in 2025 those with newer Intel laptops boasting the latest web camera technology are often facing a challenging experience.

It's not only the Intel GPU compute stack seeing some nice improvements recently but over with the Mesa 25.0-devel code for the Intel "ANV" open-source Vulkan driver there have been some new performance optimizations arriving this week.
