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,
