Devicetree
In computing, a devicetree (also written device tree) is a data structure describing the hardware components of a particular computer so that the operating system's kernel can use and manage those components, including the CPUs or SoC, the memory, the storage, the buses and the integrated peripherals. The devicetree originated as part of the Open Firmware project for SPARC-based and PowerPC-based computers, withdrawn in 2005. In 2016, a stand-alone Devicetree specification was developed by simplifying and modernizing the old specifications. Its target has switched to smaller systems and embedded systems, but is still used with some server-class systems (for instance, those described by the Power Architecture Platform Reference). Personal computers with the x86 architecture generally do not use device trees, relying instead on various auto configuration protocols (e.g. ACPI) to discover hardware. Systems which use device trees usually pass a static device tree (perhaps stored in EEPROM,...
