Status of DTS Validation in Linux Kernel
Talkat Open Source Summit Japan + AI_dev: Open Source GenAI & ML Summit + Automotive Linux Summit 2025 · 2025-12-08..12-10·
summary
Validation of DTS against DT schema drives thousands of commits over several kernel releases and cuts ARM32 warnings from ~80k to ~36k while ARM64 reaches about ~74% warning‑free targets; RISC 5 currently shows zero warnings in the measurement. The effort shows 30–40% of DTS‑touching commits come from validation and roughly ~10% of those fixes reveal real bugs (missing required properties or wrong phandle args). Results come from running mainline DT schema checks across kernel trees and counting warnings per DTB target.
