SYNOPSIS
devinfo |
[-rv] |
devinfo |
-u |
DESCRIPTION
Thedevinfo 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
-rbut 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 enabled devices in the driver tree, not just those that are attached or busy. Specify this flag twice, to also display all disabled devices in the driver tree. Without this flag, only those devices that have attached are reported.
