One Line Summary

Possible tactics for device probe ordering

Abstract

Device probe order has caused problems due to dependency issues. The current device tree solution is for a probe function to return -EPROBE_DEFER when a required resource is not available, then expect a retry of the probe later.

There have been reports that boot time can be reduced if probe order is modified to ensure dependencies will be resolved before calling a driver probe function.

This session will explore the issues surrounding probe order.
