Open Source Summit North America 2025

The test harness (aka board farm) was initially designed to enable automated testing of Linux drivers on actual hardware. This ultimately became a way to implement continuous testing on hardware, every commit or PR, a build and test is run, and results are reflected back to the commit. It is designed to cater a wide range of peripheral devices and platforms mainly for Analog Devices' Kuiper Linux distribution which is built with more than 1000 Linux device drivers compatible with Xilinx and Intel FPGAs, Raspberry Pi boards, and several other platforms.

This talk covers the design and implementation of such a fully automated test harness. The implemented architecture leverages the use of readily available components/technologies such as Jenkins, Docker, NetBox, and JFrog Artifactory and, at the same time, includes custom-built tools that can be tailored and extended to support existing or new devices and platform types.

This talk will also cover how the team handled the challenges encountered while implementing and addressing features such as resource queueing to minimize waiting time of running builds and also how we make use of sdcardmux to handle recovery.
