47 The ccw bus
50 The ccw bus typically contains the majority of devices available to a
51 s390 system. Named after the channel command word (ccw), the basic
52 command structure used to address its devices, the ccw bus contains
56 subchannel directly, but only via the I/O device on the ccw bus, the ccw

A Ddriver-model.rst11 All ccw devices are accessed via a subchannel, this is reflected in the
29 system; it is a pseudo subchannel where disconnected ccw devices are moved to
30 if they are displaced by another ccw device becoming operational on their
31 former subchannel. The ccw devices will be moved again to a proper subchannel
35 be found under bus/ccw/devices/.
37 All ccw devices export some data via sysfs.
69 1.1 Bringing up a ccw device
80 1.2 Writing a driver for ccw devices
249 The ccw driver provides a 'group' attribute. Piping bus ids of ccw devices to
