This document describes the interfaces available for device drivers that
- drive s390 based channel attached devices. This includes interfaces for

interaction with the hardware and interfaces for interacting with the
common driver core. Those interfaces are provided by the s390 common I/O
layer.

The ccw bus typically contains the majority of devices available to
a s390 system. Named after the channel command word (ccw), the basic
command structure used to address its devices, the ccw bus contains
- so-called channel attached devices. They are addressed via subchannels,
