Merged last year for the Linux 5.16 cycle was FUTEX2's futex_waitv() system call for waiting on multiple futexes in order to better match the behavior of Microsoft Windows. This FUTEX2 initiative was driven as an effort to further enhance Linux gaming performance/efficiency particularly for Valve's Steam Play. Originally there were other goals with FUTEX2 and now we are seeing another one of those being worked on: NUMA awareness...

There has been a number of different efforts in recent time to further enhance the Linux kernel's scheduler to better adapt to modern hardware architectures whether it be for Intel hybrid CPU designs, adapting to new CPU cache configurations, or just better scaling with today's ever-increasing core counts. Another scheduler effort detailed this week is "Nest" that aims to keep tasks on "warm cores" with hopes of lower latency due to being already at higher clock/performance states and ideally operating at an optimal turbo/boost frequency. The Nest developers find that their scheduler "improves performance 10%-2x and can reduce energy usage" with modern hardware...

Ever since OpenPrinting took over CUPS upstream from Apple, this widely-used, open-source print server has been back to having a vibrant future. CUPS development ceased at Apple and there wasn't much going on until last year when CUPS founder Michael Sweet and OpenPrinting provided new life to the project...

For a number of years Arm CPUs on the mainline Linux kernel have supported Energy Aware Scheduling (EAS) as a means of providing the kernel's scheduler with the information to influence its scheduling decisions based on the estimated energy consumed by the CPU cores. EAS employs an energy model for helping to place tasks between the big.LITTLE cores for optimal energy efficiency and a minimal impact on throughput. Intel has been working to eventually support Energy Aware Scheduling on their x86 hybrid CPUs too...

Google for quite some time now has been working on "Ghost" as a means of controlling the Linux kernel scheduler from user-space and/or eBPF programs. Ghost provides an extensive API so developers can alter the kernel's scheduler behavior from user-space or eBPF and fine-tune the scheduling behavior based on system preferences...

Since NTFS3 was mainlined last year in the Linux kernel as a modern NTFS read/write file-system driver developed by Paragon Software, it's mostly just been some fixes since then and other minor updates. A new NTFS3 patch series sent out today is at least preparing a new feature for this kernel driver...

One of many changes to find with next month's Ubuntu 22.10 release is Debuginfod integration...

Now that Ubuntu 22.10 is into its feature freeze and its Linux 5.19 based kernel landed as well as moving to the GCC 12.2 compiler, I've begun testing this forthcoming Ubuntu Linux (non-LTS) release on more systems. For the current-flagship Intel Xeon Platinum 8380 "Ice Lake" processors, Ubuntu 22.10 does deliver some performance advantages over the current Ubuntu 22.04.1 LTS release. However, Ubuntu 22.10 still trails in a distance behind Intel's own Clear Linux platform for the most aggressive out-of-the-box performance.
