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.

The BeOS-inspired Haiku open-source operating system has published their latest monthly development report. During December they worked on a number of features and fixes as well as getting a modern web browser up and running.

For those looking toward better I/O performance with Java, there is JUring for making use of IO_uring and the reported performance benefits are very enticing.

Open Image Denoise 2.3.2 was released by Intel on Monday. Contrary to being a point release, it's actually an exciting update.

OpenZFS 2.3 is out as stable this evening as the latest major feature release to this open-source ZFS file-system implementation used on Linux and FreeBSD systems. OpenZFS 2.3 is heavy on new features.

The Fedora Engineering and Steering Committee (FESCo) has granted approval of the change proposal for shipping Fedora Linux WSL images to enhance the user experience for those wanting to run this Linux distribution within the confines of Microsoft's Windows 11 WSL2 environment.

Last month with the launch of Intel Battlemage with the Arc B580 graphics card, there was fairly nice open-source GPU compute performance but with some outliers... Today it's a pleasure to report that with the newest open-source GPU compute stack as of this past week, there are some nice Xe2 / Battlemage improvements for enhancing the performance of some OpenCL workloads and also correcting the performance of some workloads that were in poor standing on launch day.

Oracle today announced the Oracle Linux Enhanced Diagnostics (OLED) as their newest project that aims to enhance the debugability of the Linux kernel.

The "48.alpha" releases of GNOME Shell and Mutter were tagged on Sunday for this week's release of the GNOME 48 Alpha in leading up to the GNOME 48.0 stable release in mid-March.

Philip Rebohle working for Valve has just released DXVK 2.5.3 as the newest update to this Direct3D 9 / 10 / 11 implementation over the Vulkan API that is used for enjoying older Windows games on Linux.

Last year an AMD engineer proposed the notion of "Attack Vector Controls" for the Linux kernel to re-think how the CPU security mitigation handling is done and making it easier for system administrators/users to toggle the mitigations they are concerned about or not.

A change to the Linux 6.13 kernel contributed by a Microsoft engineer ended up changing Linux x86_64 code without proper authorization and in turn causing troubles for users and now set to be disabled ahead of the Linux 6.13 stable release expected next Sunday.

Alibaba engineers have recently been working through some AMD Linux kernel graphics driver bugs uncovered during suspend-and-resume testing with AMD graphics cards.

Queued up into the networking subsystem's "net-next" branch last week ahead of the Linux 6.14 kernel cycle is AF_XDP zero-copy support for the common Intel Gigabit Ethernet "IGB" driver. With this the AF_XDP performance improvements can be quite dramatic in leveraging this zero-copy path.

A nice Christmas surprise for 2024 was Meta engineer Rik van Riel posting Linux kernel patches for making use of the AMD INVLPGB instruction found since Zen 3 processors for broadcast TLB invalidation.

Hyprland is now the latest Wayland compositor supporting the color management protocols and allowing High Dynamic Range (HDR) color support with capable displays.
