Earlier this month I wrote about Intel engineers working on more big optimizations to the Linux kernel with a focus on enhancing the kernel's performance at high core counts. The numbers shared then were very promising and since then I've had more time looking at the performance impact of Intel's stellar software optimization work and its impact on real-world workloads. Here is a look at how Intel's pending kernel optimization patches are a huge deal for today's high core count servers.

Ubuntu Touch as the community maintained version of Ubuntu Linux for smartphones and tablets has for years been frustratingly limited to Ubuntu 16.04 LTS as its base operating system for when Canonical had abandoned their smartphone ambitions. Today though that has finally changed with Ubuntu Touch OTA-1 Focal having been released that moves things forward to an Ubuntu 20.04 LTS base.
Back in October Google announced their Compute Engine C3 instances in private preview that featured 4th Gen Xeon Scalable "Sapphire Rapids" processors as well as making use of Google's custom Intel Infrastructure Processing Unit (IPU). Since then, back in January, was the big Sapphire Rapids launch with the likes of the Xeon Platinum 8490H being released. Last month meanwhile Google promoted the C3 VMs to public preview state. The Sapphire Rapids C3 VMs remain in "public preview" from Google Cloud during which time there are no charges involved for the CPU costs. For those wondering about the core-for-core performance of Sapphire Rapids in Google Cloud, here are my initial benchmarks of the C3 series.
Going back to late 2021 was the initial GCC compiler patch for "Ampere-1" for that next-gen AArch64 server processor while last year this successor to Ampere Altra (Max) was formally announced under the AmpereOne brand. That initial compiler support appeared in GCC 12 while ahead of the GCC 13 release in the coming weeks has been some last minute tuning for the AmpereOne cost table.
Thanks to forthcoming work out of Red Hat, the Linux 6.4 Device Mapper (DM) code is expected to see some optimization work that can significantly benefit concurrent I/O performance... In one case at least acquiring buffers now about 25 times faster.
While XWayland is in fairly good shape for enjoying both native and emulated games relying on X11 to run atop Wayland compositors for Linux gaming, occasionally different peculiar issues are uncovered. The most recent issue analyzed and addressed in XWayland Git is over the game Resident Evil 6 causing XWayland to hang and consume 100% of the CPU resources on launching that title.

With the Linux 6.2 release kernel developers addressed "a tasty target for attackers" after it was realized that the per-CPU entry data was not being randomized, even in the presence of Kernel Address Space Layout Randomization (KASLR). The per-CPU entry area randomization has been present since Linux 6.3 but then was realized it's being activated even if KASLR was disabled, so now that is changing to avoid possible confusion.
