While not yet an official project, they have begun working on a new KDE Login Manager for improving the situation...

The Linux 6.15 kernel is set to remove support for IBM Cell Blade servers for those server platforms from around two decades ago that used the Cell Broadband Engine Architecture processors. IBM Cell Blades at the time powered a few supercomputers but these IBM QS20 / QS21 / QS22 platforms are no longer relevant and the IBM Linux kernel maintainers no longer even have these platforms available/running. With no apparent users remaining, it's time to say goodbye to the IBM Cell Blades from the mainline kernel...

Earlier this month for launch-day there were NVIDIA GeForce RTX 5070 Linux GPU compute benchmarks. The graphics/gaming benchmarks of the GeForce RTX 5070 on Linux were held up by waiting for a new R570 Linux driver release with proper support for this new Blackwell graphics card. Last week that new Linux driver arrived in the form of the NVIDIA 570.133.07 Linux build. That new NVIDIA Linux driver is working out great with the GeForce RTX 5070 Founder's Edition and in this article are some initial Linux gaming/graphics performance benchmarks for that new graphics card competing with the AMD Radeon RX 9070 series.

Last month Bcachefs lead developer Kent Overstreet talked of Bcachefs getting to the point of freezing its on-disk format with future on-disk format updates slated to be optional. With today's Bcachefs pull request for Linux 6.15, it's now being treated as "soft frozen" and also landing other new features for this copy-on-write file-system. Among the new features is case insensitive file/folder support contributed by Valve...

There was a hiccup yesterday with no Linux 6.14 release or 6.14-rc8 otherwise... Linus Torvalds has a very good track record of sticking to his Sunday release regiment. Yet yesterday was quiet. Today though Linus Torvalds released the Linux 6.14 kernel as the newest stable version. Linux 6.14 is what's set to go on and power Ubuntu 25.04, Fedora 42, and other spring 2025 Linux distribution releases...

What a week. Last week Intel published a new AVX10 whitepaper where they dropped the optional 512-bit support of AVX10.2 and confirmed future P and E cores will have AVX10.2-512 support unconditionally. A very welcome change by Intel albeit late in rushing to get patches out to change that behavior ahead of the GCC 15 stable compiler release as well as working similar changes into the LLVM Clang compiler. As of today those GNU Compiler Collection patches have been merged to prepare for AVX10.2 always having 512-bit support available...

Among the early pull requests submitted in advance of the Linux 6.14 stable release and in turn the Linux 6.15 merge window opening were the x86 FPU updates.

Coming out this week was an updated AVX10 whitepaper from Intel with the surprising decision that 512-bit floating point and integer support is no longer considered optional for AVX10.2. AVX10.2 now mandates 128 / 256 / 512-bit support and in turn also dropped the 256-bit embedded rounding support with the focus on 512-bit. The LLVM/Clang compiler had seen its AVX10 support designed around Intel's original AVX10 design assumptions and thus now is being modified to address these changes...

Among the earliest of pull requests this week ahead of the Linux 6.15 merge window expected to begin tomorrow were the media subsystem updates.
