One Line Summary

Describe the use of devicetree overlays in Juniper products.

This session was merged into "Device Tree Overlays".

Abstract

At Juniper, we use devicetree overlays to manage a variety of cards which can be inserted and removed at runtime.

In this session, I will describe the basic system architecture, our requirements, and why we decided to use devicetree overlays to meet those requirements. I will also dive into the actual implementation of our card management framework in the Linux kernel, and explore some of the limitations of the current devicetree overlay code.
