.Dd July 5, 2022 .Dt DEVINFO 8 .Os .Sh NAME .Nm devinfo .Nd print information about system device configuration .Sh SYNOPSIS .Nm .Op Fl rv .Nm .Fl u .Nm .Fl p Ar dev Op Fl v .Sh DESCRIPTION The .Nm utility, without any arguments, shows the hierarchy of devices available in the system, starting from the .Dq nexus device.
p The following options are accepted. l -tag -width indent t Fl 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. t Fl u Displays the same information as with .Fl 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. t Fl 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. This flag also displays verbose information about each device. t Fl p Ar dev Display the path of .Ar dev back to the root of the device tree. .El .Sh SEE ALSO .Xr systat 1 , .Xr devinfo 3 , .Xr devctl 8 , .Xr iostat 8 , .Xr pciconf 8 , .Xr vmstat 8 , .Xr devclass 9 , .Xr device 9 .Sh AUTHORS .An Mike Smith Aq Mt msmith@FreeBSD.org
