PRTCONF(1M)PRTCONF(1M)NAME
prtconf - print system configuration
SYNOPSIS
/usr/sbin/prtconf [-V] | [-F] | [-m] | [-x] | [-bpv] | [-acdDPv]
[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", "compat‐
ible", "banner-name" and "model".
-c
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.
-d
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.
-D
For each system peripheral in the device tree, displays the name
of the device driver used to manage the peripheral.
-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.
-m
Displays the amount system memory in megabytes. This flag must
be used by itself.
-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 displayed using this option
is a snapshot of the initial configuration and may not accurately
reflect reconfiguration events that occur later.
-P
Includes information about pseudo devices. By default, informa‐
tion 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-dependent.
-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 applica‐
ble to this platform and the firmware is not 64-bit ready, it
displays a descriptive message on the standard output and exits
with a non-zero return code. The hardware platform documentation
contains 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 informa‐
tion 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.
