As part of the multi-year effort to overhaul the Linux kernel's printk() code there has been much work in recent months around threaded console printing so each registered console would have a kernel thread and console printing would be decoupled from the printk() callers. That work was aimed for Linux 5.19 but then reverted due to troubles. There is now a new implementation in the works...

Fedora Linux releases whether they be development/beta snapshots or the stable releases are known for slipping all too often. Fedora will often delay due to blocker bugs as they aim to deliver a bleeding-edge yet reliable Linux distribution and thus a week or two delay here and there isn't uncommon at all. While they have been delivering more timely releases than in the past with their notorious delays, for Fedora Linux 37 Beta they have delivered on the feat of an on-time release...

Overnight some fresh workarounds were merged into Mesa 22.3-devel as the latest Linux driver improvements for Intel's forthcoming discrete graphics cards...

Back in July I called attention to the issue how Linux 5.19 was set to break Alder Lake P graphics support unless moving to new graphics micro-controller "GuC" firmware in tandem. That user-space breakage is frowned upon and following that article the upstream DRM kernel maintainers outlined explicit requirements around firmware not breaking driver support. Intel engineers ended up submitting a quick fix for Linux 5.19 to still support the existing firmware while now a more adequate solution has been devised...

With Fedora 39 next spring it will likely replace DNF, libdnf, and dnf-automatic with the new DNF5 packaging tool and libdnf5 support library. DNF5 should improve the user experience and deliver better performance for dealing with software management on Fedora Linux...

Mesa recently landed BPTC software fallback handling that is a requirement for OpenGL 4.2 support but BPTC is not natively supported by all GPU hardware, particularly on the embedded side. That software emulation support for BPTC is similar to what already has existed within Mesa for the ASTC and ETC formats too. A merge request is pending that also adds S3TC software fallback handling, which helps out some of the smaller, embedded GPU drivers too for getting more games running that are dependent on S3 Texture Compression...
