With the Raspberry Pi Foundation recently having begun rolling out a Linux 4.19-based kernel to Raspberry Pi boards, here are some benchmarks looking at the performance of two Raspberry Pi systems with the new Linux 4.19 kernel compared to its previous 4.14 kernel.

As a change in acknowledging the increasing Arm SoC core counts as more vendors take stabs at higher-end server chips, the default 64-bit Arm (ARM64 / AArch64) kernel image as of Linux 5.1 will default to supporting 256 CPUs compared to the current default limit of 64 CPU cores.

In a recent post, Torvalds shared some thoughts about ARM processors and servers, and people thought he was dismissing ARM's future on servers and the cloud. Here's what he really meant.

The Raspberry Pi folks have been working the past few months on upgrading their kernel in moving from Linux 4.14 to 4.19. That roll-out has now begun.

We've been looking forward to the possibility of having a nice 64-bit ARM Linux laptop with decent power and nice build quality. Several major vendors having been rolling out Windows ARM laptops powered by Qualcomm chips and the like with decent specs and quality, unlike some of the cheap ARM Linux laptop efforts we've seen. For those Windows ARM laptops, headway is being made in being able to run Linux on them.

Pine64 announced the Pinebook laptop in 2016. The ultra cheap ($89 and up) laptop was based on Allwinner A64 quad core Cortex A53 processor coupled with 2GB RAM, 16GB storage, and a 11.6″ or 14″ display. It was never meant to be a replacement for your current laptop due to the low end specifications, but you could still use it to tinker with Arm Linux or *BSD, as a lightweight portable terminal, etc…

Since receiving the powerful NVIDIA Jetson AGX Xavier with its ARMv8 Carmel cores on this Tegra194 SoC a while back, it's been quite a fun developer board for benchmarking and various Linux tests. One of the areas I was curious about was whether GCC or Clang would generate faster code for this high performance ARM SoC, so here are some benchmarks.

The last time that I wrote about non-Raspbian Linux on the Raspberry Pi, I overlooked Manjaro because I thought their ARM project had been shut down. This error was pointed out to me in a comment to that post, and I subsequently found the Manjaro ARM re-launch announcement from last spring.

In recent years, we’ve started to see Windows 10 mini laptops with 6″ to 8″ display and a foldable keyboard coming to market thanks to products such as GPD Pocket 2 or One Mix 2 Yoga. They offer a full Windows 10 experience in an ultra-small form factor, but you’d still need to carry your phone around with you for things like calls or SMS.
