prtconf(1M) System Administration Commands prtconf(1M)NAMEprtconf - print system configuration
SYNOPSIS
/usr/sbin/prtconf [-V] | [-F] | [-x] | [-bpv]
| [-acDPv] [dev_path]
DESCRIPTION
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 informa‐
tion for that device node.
OPTIONS
The following options are supported:
-a Display all the ancestors device nodes, up to the root
node of the device tree, for the device specified on the
command line.
-b Display the firmware device tree root properties for the
purpose of platform identification. These properties are
"name", "compatible", "banner-name" and "model".
-c Display the device subtree rooted at the device node spec‐
ified on the command line, that is, display all the chil‐
dren of the device node specified on the command line.
-D For each system peripheral in the device tree, displays
the name of the device driver used to manage the periph‐
eral.
-F A SPARC-only option. 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.
-p 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 dis‐
played using this option is a snapshot of the initial con‐
figuration and may not accurately reflect reconfiguration
events that occur later.
-P Includes information about pseudo devices. By default,
information regarding pseudo devices is omitted.
-v Specifies verbose mode.
-V 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-depen‐
dent.
-x Reports if the firmware on this system is 64-bit ready.
Some existing platforms may need a firmware upgrade in
order to run the 64-bit kernel. If the operation is not
applicable to this platform or the firmware is already
64-bit ready, it exits silently with a return code of
zero. If the operation is applicable to this platform and
the firmware is not 64-bit ready, it displays a descrip‐
tive message on the standard output and exits with a non-
zero return code. The hardware platform documentation con‐
tains more information about the platforms that may need a
firmware upgrade in order to run the 64-bit kernel.
This flag overrides all other flags and must be used by
itself.
OPERANDS
The following operands are supported:
dev_path The path to a target device minor node,
device nexus node, or device link for which
device node configuration information is
displayed
EXIT STATUS
The following exit values are returned:
0 No error occurred.
non-zero With the -F option (SPARC only), a non-zero return
value means that the output device is not a frame
buffer. With the -x option, a non-zero return value
means that the firmware is not 64-bit ready. In all
other cases, a non-zero return value means that an
error occurred.

openprom(7D)NOTES
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 poten‐
tially 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
use.
On x86 platforms, the use of prtconf-vp provides a subset of informa‐
tion from prtconf-v. The value of integer properties from prtconf-vp
might require byte swapping for correct interpretation.
