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...

Over the past month of trying out Intel Alder Lake processors on Linux, one of the questions that has come up a few times but not readily disclosed is whether it's still worthwhile on this latest-generation process to boot with "mitigations=off" to disable CPU security mitigations to help squeeze out some otherwise lost performance. Here are some benchmarks to answer that questions.

When debugging graphics driver/API issues or performance profiling and relying on shader dumps, the size of such dumps can quickly add up due to all of the state collected, etc, but also inefficiencies when not within contiguous memory. Fortunately for Mesa's Radeon Vulkan driver "RADV" for pairing with the Radeon GPU Profiler there is a significant improvement that just landed for yielding smaller file sizes...
