<title>Introduction</title>
<para>
This document describes the interfaces available for device drivers that
drive s390 based channel attached devices. This includes interfaces for
drive s390 based channel attached I/O 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,
visible on the css bus. A device driver, however, will never interact
with the subchannel directly, but only via the device on the ccw bus,
so-called channel attached devices. They are addressed via I/O
subchannels, visible on the css bus. A device driver for
channel-attached devices, however, will never interact with the
subchannel directly, but only via the I/O device on the ccw bus,
the ccw device.

Some interfaces are available to other drivers that do not necessarily
have anything to do with the busses described above, but still are
indirectly using basic infrastructure in the common I/O layer.
One example is the support for adapter interrupts.
