Overview of System Device Tree Generator (SDTGen)

The System Device Tree Generator (SDTGen) is a tool designed by AMD to convert it’s proprietary output formats from the AMD Vivado Design Suite into a comprehensive system device tree. This tool plays a crucial role in modernizing and streamlining the process of hardware configuration for multi-domain software systems. For a detailed understanding of SDTGen’s intent and purpose, refer to the page titled Software Hardware Exchange Loop (SHEL) Flow intent and purpose

Device Trees vs. System Device Trees

SDTGen produces a system device tree, which provides a holistic view of the entire system’s hardware configuration, encompassing components relevant to various software domains. In contrast, a device tree is specifically used by the Linux kernel to describe hardware components. For a deeper dive into these differences, see the page Understanding System Device Tree vs. Device Tree
