While all of the software components are out there now for being able to run NVIDIA's proprietary driver stack with modern (GBM-based) Wayland compositors by default, including XWayland support, Fedora Workstation currently defaults to using an X.Org based session with the green binary blob. However, for Fedora 36 next spring they are planning on using the Wayland-based desktop here too...

Back in September Intel originally posted Linux patches for "Software Defined Silicon" for being able to activate extra CPU features present in the processor's silicon but not exposed by default unless the cryptographically secure process with this SDSi driver was performed. Intel appears to be moving toward allowing licensable processor features that can be activated after the fact and today a new version of that SDSi Linux driver appeared...

AWS recently introduced Amazon Linux 2022 in preview form as the latest iteration of their Linux distribution now based on Fedora with various alterations to catering to their customers running it on EC2.

Intel's OpenSWR driver has also now been removed from mainline...

The Panfrost Gallium3D OpenGL driver and PanVK open-source drivers in Mesa have come a long way via reverse-engineering for Arm Mali graphics support. However, to this point the focus has been on Arm's "Midgard" and "Bifrost" architectures while the newer "Valhall" architecture has been around the past two years. The Panfrost effort for bringing up Valhall is now getting underway...

XWayland is increasingly great shape especially when it comes to fulfilling the needs of gamers with simply running games lacking native Wayland support with great speed. But when it comes to other use-cases there are occasionally gaps and areas not yet fulfilled by XWayland versus the conventional X.Org Server. One of the latest examples of a feature now correctly wired up is touchpad gesture handling...

Added to the in-development Linux 5.16 kernel was cluster-aware scheduling designed to enhance system performance where groups of CPU cores may share caches or similar and thus the scheduler could benefit from knowing that information for making more optimal task placement. But as I pointed out early on with Linux 5.16, this cluster scheduling is hurting the Intel Alder Lake performance on the new kernel. Intel is now working to correct this by making the cluster scheduling configurable and disabling this functionality by default for hybrid CPUs such as Alder Lake...
