System Administration Commands prtconf(1M)
NAME
prtconf - print system configuration
SYNOPSIS
/usr/sbin/prtconf [-V] | [-F] | [-x] | [-bpv] | [-acdDPv]
[dev_path]
DESCRIPTION
The prtconf command prints the system configuration informa-
tion. The output includes the total amount of memory, andthe configuration of system peripherals formatted as a dev-
ice tree. If a device path is specified on the command line for thosecommand 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 specified on the command line.-b Display the firmware device tree root properties for
the purpose of platform identification. These proper-
ties 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 allthe children of the device node specified on the com-
mand line.-d Display vendor ID and device ID for PCI and PCI
Express devices, in addition to the nodename.-D For each system peripheral in the device tree,
displays the name of the device driver used to manage the peripheral.-F 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 theSunOS 5.11 Last change: 3 Feb 2010 1

console, frame buffer device or a non-zero exit code.
For example, if the console frame buffer on aSUNW,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 pro-
vided by the firmware (PROM) on SPARC platforms or thebooting system on x86 platforms.The device tree infor-
mation 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 platforms)
or booting system (on x86 platforms) version informa-
tion. This flag must be used by itself. The output is a string. The format of the string is arbitrary andplatform-dependent.
-x Reports if the firmware on this system is 64-bit
ready. Some existing platforms may need a firmwareupgrade in order to run the 64-bit kernel. If the
operation is not applicable to this platform or thefirmware is already 64-bit ready, it exits silently
with a return code of zero. If the operation is appli-
cable to this platform and the firmware is not 64-bit
ready, it displays a descriptive message on the stan-
dard output and exits with a non-zero return code. The
hardware platform documentation contains more informa-
tion about the platforms that may need a firmwareupgrade 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 nodeSunOS 5.11 Last change: 3 Feb 2010 2

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 nota 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.ATTRIBUTES

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 iscurrently 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.SunOS 5.11 Last change: 3 Feb 2010 3

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.SunOS 5.11 Last change: 3 Feb 2010 4
