Writing a device driver is often viewed as a daunting task, fraught with complexities and requiring arcane knowledge of little-known kernel secrets.
The goal of this section is to demystify the process; you'll learn everything you need to know about how to write device drivers, starting with what they do, how they work, and how they fit into the overall system.
List of documents to get started -
- Fuchsia Driver Framework - Overview of driver manager and driver host
- Fuchsia drivers - Overview of fuchsia driver model.
- Device and driver model - Documents that explain device and driver model
- Driver development - Documents related to interrupts, DMA and other concepts for developing drivers
- Driver architectures - Documents related to architecture of specfic driver types
The sections are listed above in default reading order, but it's perfectly fine to jump around and read them in order of interest or applicability.
