Running Long-Term Stable Kernel on Cutting Edge Silicon

on YouTube ↗47m

" summary

LTSI takes a community LTS kernel and backports selected newer drivers and fixes using Yocto recipes and Patchwork so vendors can run cutting‑edge silicon on an LTS base. The project pulls 390 patches into the 3.4 LTS tree, builds BSPs with Yocto, and validates on ARM v7 QBox boards with 173 test cases × ~10 variants (~1,000 runs), finding 99.2% compatibility but uncovering a hidden dependency that required three days of bisection to fix. The result is an LTSI kernel that largely works but needs heavy integration testing for complex use cases.
