Coding Neon Kernels for the Cortex-A53(destevez.net) Some weeks ago, I presented at FOSDEM my work-in-progress high performance SDR runtime qsdr. I showed a hand-written NEON assembly implementation of a kernel that computes \(y[n] = ax[n] + b\), which I used as the basic math block for benchmarks on a Kria KV260 board (which has a quad-core ARM Cortex-A53 at 1.33 GHz). In that talk I glossed over the details of how I implemented this NEON kernel.

New Apple Silicon Co-Maintainer Steps Up for the Linux Kernel(phoronix.com) This week was the dramatic decision by Asahi Linux lead developer Hector Martin to step down as upstream kernel maintainer for the Apple Silicon (ARM) code following friction with other kernel developers over Rust affairs within the kernel.

Adélie Linux 1.0-BETA6 Released(adelielinux.org) TULSA (December 15, 2024) — The Adélie Linux distribution’s sixth beta release, 1.0-BETA6, is now available for download1 for 32- and 64- bit ARM, POWER, and x86. Compatible systems include smartphones, game consoles, ’90s-era PCs, and supercomputers2.
First Impressions: Lenovo T14s with Qualcomm Snapdragon ARM64 CPU(freebsd.org) Those of you how know me, know that I am not a big fan of the X86 architecture, which I think is a bad mess, mangled by market power considerations, rather than the CPU architecture this world actually needs, in particular in terms of performance/energy ratio.

Ask HN: Could Qualcomm Buy Intel?(ycombinator.com) I saw this floating around. Unsure if it’s serious. Seems like it would be a huge win for Qualcomm: they’d get fabs, all the x86 IP (or maybe that’d have to be spun out), system integrator know how for use with Qualcomm’s ARM stuff, networking, etc etc. all of this would help them with their VMWare side: maybe they go the HP route with green lake and ship the hardware with the software a la Sun Microsystems?
