The latest partnership between Microsoft and Canonical is an announcement today of native .NET availability for Ubuntu 22.04 LTS hosts as well as containers...

Up to this point loading updated CPU microcode on AMD processors under Linux has checked just to ensure every physical CPU core was loaded with the new microcode but not sibling threads for SMT processors. While logically that makes sense, it turns out some AMD microcode updates do carry out per-thread modifications that means the microcode updating needs to be carried out on every thread. A Linux fix is on its way to the kernel to adjust that behavior...

As part of today's "drm-misc-fixes" pull request, NVIDIA Ampere GA103 GPU support is set to be added to the Nouveau DRM driver with Linux 6.0...

Ahead of the upcoming openSUSE/SUSE Adaptable Linux Platform (ALP), whether to raise the x86_64 micro-architecture feature level required by the Linux OS continues to be evaluated and what options there are for making use of newer x86_64 instruction set extensions without necessarily forcing tightened CPU requirements / eliminating old hardware support...

When it comes to Linux on Arm laptops the recent excitement has been around the Asahi Linux porting work for the Apple M2 MacBooks and Linux 6.0 supporting the Qualcomm Snapdragon 8cx Gen3 and the flagship Lenovo ThinkPad X13s Arm laptop. Launched a few years ago though was the Lenovo Yoga C630 powered by a Qualcomm Snapdragon 850 and thanks now to the work of Linaro that older Arm laptop is seeing Linux support improvements...

LZ4 v1.9.4 is out today as the first point release in nearly two years for this BSD-licensed, speedy, lossless compression algorithm...

After Qualcomm announced their Cloud AI 100 Accelerator back in 2019, in 2020 during the early days of the pandemic they posted a Linux driver for this accelerator. That driver didn't get picked up for the mainline Linux kernel and two years later there still is little fanfare around the Qualcomm AI Cloud Accelerator hardware. However, now they have posted a new Linux driver that goes the DRM driver route...

Yesterday marked the release of Linux 6.0-rc1 and as such the merge window is now over and no more feature work is set to land in this kernel version. Here is my write-up of all the interesting new features and changes/improvements coming for Linux 6.0.

Greg Kroah-Hartman as the Linux kernel's stable maintainer and effectively Linus Torvalds' second-in-command has suggested avoiding Intel Alder Lake laptops. While much of the Alder Lake laptop support for Linux is in good shape, the exception is around web cameras. These newer laptops with Intel's latest web-camera tech are not currently supported by the mainline kernel and require proprietary software for use. Some platforms like Ubuntu and ChromeOS are picking up these blobs for now while a proper open-source, upstream solution is likely months -- or likely about one year -- away...

AMD today sent out revised patches for improving the AMD P-State CPU frequency scaling Linux driver that aims to provide better power efficiency than the generic ACPI CPUFreq driver that has long been relied upon for AMD processors...

Those on rolling-release Linux distributions that are quick to adapt to new toolchain updates are finding Easy Anti Cheat (EAC) enabled games breaking when running on the recently released Glibc 2.36. The breakage stems from the DT_HASH section being dropped in GNU C Library but EAC being among the few software still expecting that section rather than DT_GNU_HASH...

Wine 7.15 is out a day late as the newest development snapshot of this open-source software for enjoying Windows games and applications on Linux and other platforms. Wine is also what serves as the base for Valve's Proton that powers Steam Play...

With the Ryzen 6000 "Rembrandt" mobile processors most exciting about these Zen 3+ SoCs has been the energy efficiency improvements and moving from Vega to RDNA2 graphics as with the Radeon 680M found on the Ryzen 7 PRO 6850U that I have been running many Linux benchmarks on over the past several weeks. For those wondering if it pays off moving to a newer Linux kernel or Mesa version with Radeon 680M integrated graphics, here are some reference benchmarks I recently conducted...

While support for the loongArch Chinese CPU architecture was merged in Linux 5.19, it wasn't actually enough to yield a booting system due to some driver code not yet being finished and ready for merging in time. LoongArch was allowed to merge that preliminary code in v5.19 so the Glibc support could land and now for Linux 6.0 more of the CPU port is ready to hit the kernel...

When it comes to the Apple M1 and M2 support on Linux, one of the biggest obstacles to suitable daily use for end-users is the current lack of GPU acceleration. Reverse engineering has been happening for the Apple Silicon graphics processor, early experiments being carried out under macOS and Asahi's m1n1 environment, and the next step will be to start writing a Direct Rendering Manager (DRM) kernel driver. To some surprise, the feasibility of writing this DRM kernel GPU driver in the Rust programming language is being explored...
