| ============================== | |
| 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. | |
