Device driver view

6.10 LPAR mode z/VM guest KVM guest

This view groups devices by the device drivers that control them.

The device driver view is of the form:

/sys/bus/<bus>/drivers/<driver>/<device_bus_id>

where:
<bus>
is the device category, for example, ccw or ccwgroup.
<driver>
is a name that specifies an individual device driver or the device driver component that controls the device.
<device_bus_id>
identifies an individual device.
Note: DCSSs are not represented in this view.
