Arm Neoverse roadmap for server-class systems
At Arm TechCon, Arm announced a roadmap for server-class systems called Neoverse. The company plans to release IP that will enable licensees to build fast multi-core systems without going through the expense and bother of designing their own CPU cores. The roadmap includes 7nm and 5nm parts with an annual cadence for improvements.
Neoverse is part of a broader strategy that identifies opportunities for Arm based systems, with a “cloud to edge infrastructure foundation for a world of one trillion intelligent devices”.
Linux kernel to support big/little process scheduling (Phoronix)
The plan is to better handle “misfit” tasks, which need more CPU but are currently scheduled on a slower “little” core. The patch lands in the 4.20 kernel. This is primarily targeted at CPU cores that incorporate fast high speed cores with slower but more memory efficient secondary cores.
Fedora 29 is on its way
Fedora 29 is due to be shipped live on Tuesday, October 30, 2018. Improvements in the release target IOT support for smaller 32-bit and 64-bit Arm devices, including newly improved ZRAM support for swap in memory constrained devices. Fedora 29 is one of the first operating systems also to support Go 1.11, which has substantial performance improvements over earlier Go releases on arm64 especially on crypto codes.

NetBSD ARM64 images for SBSA compliant systems
Jared McNeill has been working on code to boot NetBSD cleanly on SBSA compliant systems. SBSA (“Server Base System Architecture”) is a standard for arm64 server designs, with the goal that a server will be able to support booting a wide range of operating systems without the OS vendor needing to customize the boot code for each vendor hardware.
