Projects in the topic kernel
The Linux kernel is a free and open-source, monolithic, modular, multitasking, Unix-like operating system kernel.

Tronsmart has a Rockchip rk3368 based set-top-box [1].

AFAIK, wireshark is the best Linux tool for analyzing network traffic. Primarily intended for Ethernet networks, there is now also support for very different protocols (e.g. USB). Sadly, there is no support for fibre channel, most likely because there is even no infrastructure in the kernel.

Recently I became a (not very proud) owner of Acer Aspire Switch 10E, a small notebook/tablet convertible based on Intel baytrail platform. Replacing preinstalled (32-bit!) Windows 8.1 with (64-bit) openSUSE proved more challenging than expected, mostly because the device is haunted by a 32-bit UEFI so that it took me a week to make it boot without an external USB flash disk.

We had old arndale images working, but those were based on openSUSE-12.x which is now long obsolete and bad (e.g. missing security updates).
