The big set of open-source graphics driver updates for Linux 6.15 have been merged but Linux creator Linus Torvalds isn't particularly happy with the pull request. In particular, he's unhappy with some new "hdrtest" testing code being built as part of full kernel builds and the "turds" it leaves behind and this code "needs to die" at least from the perspective of non-DRM driver developers...

While fresh off the GNOME 48 release, GNOME desktop developers aren't slowing down and there's been some interesting activity to report this week...

Set to be merged for the Linux 6.15 kernel is the very initial NOVA driver core code that will be incrementally built up over time in succeeding kernel versions. For Linux 6.15, this open-source NVIDIA kernel driver isn't of any use for end-users as it's just the very preliminary pieces to begin crafting the foundation for the driver that is leveraging the NVIDIA GSP found with Turing and newer hardware. In preparation for future kernel cycles, the NOVA skeleton driver pieces were posted for review yesterday to begin fleshing out more of the driver's design...

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...
