Explore the current state of Device Tree Source (DTS) validation in the Linux kernel through this 39-minute conference talk by Krzysztof Kozlowski from Qualcomm, presented at a Linux Foundation event. Learn about the significant benefits of Device Tree bindings in the current DT schema format, particularly their ability to validate DTS correctness against established bindings. Discover the challenges that emerged when validation was first introduced, revealing that in-kernel DTS files failed to pass validation requirements. Gain insights into the progress made over several years and thousands of commits to address these validation issues. Find out which architectures among the main Device Tree users have achieved warning-free status and which SoC subsystems demonstrate compliant DTS implementations. Understand the ongoing efforts and current status of Linux kernel DTS validation initiatives, providing valuable perspective on the evolution of Device Tree validation practices in kernel development.
