Device Tree: Past, Present, and Future

Neil Armstrong

Since the switch of the ARM Linux support from the stable PowerPC Device Tree support, it became an important piece of software used to describe all sorts of devices based on very different hardware architectures.
Currently, BSD* Unixes and even the Zephyr RTOS has switched to Device Tree to describe the hardware. U-boot has also a file format using the Device Tree blob format.
Neil will present you the history of Device Tree from its origins, how it has been used for ARM from the PowerPC codebase, all the very different current usage and an overview of its future application and evolutions.

This talk was given at Linux.conf.au 2018 (LCA2018) which was held on 22-26 January 2018 in Sydney Australia.

linux.conf.au is a conference about the Linux operating system, and all aspects of the thriving ecosystem of Free and Open Source Software that has grown up around it. Run since 1999, in a different Australian or New Zealand city each year, by a team of local volunteers, LCA invites more than 500 people to learn from the people who shape the future of Open Source.
