prtconf - print system configuration
/usr/sbin/prtconf [-V] | [-F] | [-m] | [-x] | [-bpv] | [-acdDPv]
The prtconf command prints the system configuration information. The
output includes the total amount of memory, and the configuration of system
peripherals formatted as a device tree.
If a device path is specified on the command line for those
command options that can take a device path, prtconf will only
display information for that device node.
The following options are supported:
Display all the ancestors device nodes, up to the root
node of the device tree, for the device specified on the command line.
Display the firmware device tree root properties for the
purpose of platform identification. These properties are "name",
"compatible", "banner-name" and "model".
Display the device subtree rooted at the device node
specified on the command line, that is, display all the children of the device
node specified on the command line.
Display vendor ID and device ID for PCI and PCI Express
devices, in addition to the nodename. If the information is known, the vendor
name and device name will also be shown.
For each system peripheral in the device tree, displays
the name of the device driver used to manage the peripheral.
Returns the device path name of the console frame buffer,
if one exists. If there is no frame buffer, prtconf returns a non-zero
exit code. This flag must be used by itself. It returns only the name of the
console, frame buffer device or a non-zero exit code. For example, if the
console frame buffer on a SUNW,Ultra-30 is ffb, the command returns:
/SUNW,ffb@1e,0:ffb0. This option could be used to create a symlink for
/dev/fb to the actual console device.
Displays the amount of system memory in megabytes. This
flag must be used by itself.
Displays information derived from the device tree
provided by the firmware (PROM) on SPARC platforms or the booting system on
x86 platforms.The device tree information displayed using this option is a
snapshot of the initial configuration and may not accurately reflect
reconfiguration events that occur later.
Includes information about pseudo devices. By default,
information regarding pseudo devices is omitted.
Specifies verbose mode.
Displays platform-dependent PROM (on SPARC
platforms) or booting system (on x86 platforms) version information. This flag
must be used by itself. The output is a string. The format of the string is
arbitrary and platform-dependent.
The following operands are supported:
A legacy flag that reported if the firmware on this
system is 64-bit ready. As illumos only runs on 64-bit platforms, this flag is
kept for compatibility only, and zero is always returned.
This flag overrides all other flags and must be used by
The path to a target device minor node, device nexus
node, or device link for which device node configuration information is
The following exit values are returned:
No error occurred.
With the -F option, a non-zero return value means
that the output device is not a frame buffer. In all other cases, a non-zero
return value means that an error occurred.
See attributes(7) for descriptions of the following attributes:
The output of the prtconf command is highly dependent on the version of
the PROM installed in the system. The output will be affected in
potentially all circumstances.
The driver not attached message means that no driver is
currently attached to that instance of the device. In general, drivers are
loaded and installed (and attached to hardware instances) on demand, and
when needed, and may be uninstalled and unloaded when the device is not in
On x86 platforms, the use of prtconf -vp provides a
subset of information from prtconf -v. The value of integer
properties from prtconf -vp might require byte swapping for
