DESCRIPTION
The
devinfo utility, without any arguments, shows the hierarchy of devices available in the system, starting from the “nexus” device.
The following options are accepted.
-
-r
-
Causes hardware resource information (such as IRQ, I/O ports, I/O memory addresses) to be also listed, under each device that has reserved those resources.
-
-u
-
Displays the same information as with
-r but sorts by resource type rather than by device, allowing to review the set of system resources by usage and available resources. I.e., it lists all the IRQ consumers together.
-
-v
-
Display all devices in the driver tree, not just those that are attached or busy. Without this flag, only those devices that have attached are reported.
