Device category view

Edit online

7.1 LPAR mode z/VM guest KVM guest

This view groups devices by major categories that can span multiple device drivers.

The device category view does not sort the devices according to their device drivers. All devices of the same category are contained in a single directory. The device category view is of the form:

/sys/bus/<bus>/devices/<device_bus_id>

where:
<bus>
is the device category, for example, ccw or ccwgroup.
<device_bus_id>
identifies an individual device.
Notes:
  • DCSSs are not represented in this view.
  • /sys/bus/ccw/devices includes virtio CCW devices.

Examples

  • This example shows the path for a CCW device:

    /sys/bus/ccw/devices/0.0.b100

  • This example shows the path for a CCW group device:

    /sys/bus/ccwgroup/devices/0.0.a100

  • This example shows the path for a cryptographic device:

    /sys/bus/ap/devices/card3b
