==============================
Driver implementer's API guide
==============================

The kernel offers a wide variety of interfaces to support the development
of device drivers.  This document is an only somewhat organized collection
of some of those interfaces — it will hopefully get better over time!  The
available subsections can be seen below.


General information for driver authors
======================================

This section contains documentation that should, at some point or other, be
of interest to most developers working on device drivers.

Implementation Notes

This generated page is the file-by-file coverage layer; curated subsystem chapters should link here when they synthesize a multi-file control flow.
Core OS pages should be promoted from atlas-only to deep-reviewed when they explain data structures, invariants, locking, lifecycle, and C implementation snippets.
Driver-family pages are intentionally pattern-oriented unless they are part of the selected PCIe/NVMe representative device path.
