System Administration Commands prtconf(1M)
NAME
prtconf - print system configuration
SYNOPSIS
/usr/sbin/prtconf [-V] | [-F] | [-x] | [-bpv] | [-acDPv]
[dev_path]
DESCRIPTION
The prtconf command prints the system configuration informa-
tion. The output includes the total amount of memory, and
the configuration of system peripherals formatted as a dev-
ice 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.
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 speci-
fied 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 specified on the command line, that is,
display all the children of the device node speci-
fied on the command line.
-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,

System Administration Commands prtconf(1M)
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 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, information regarding pseudo devices is
omitted.
-v Specifies verbose mode.
-V Displays platform-dependent PROM (on SPARC plat-
forms) 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
applicable 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 confi-
guration 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.

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 potentially all circumstances.

The driver not attached message means that no driver is
currently attached to that instance of the device. In gen-
eral, 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 information from prtconf -v. The value of integer proper-
ties from prtconf -vp might require byte swapping for
correct interpretation.
