Maintenance 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, 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 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 all the 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. 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 Illumos Last change: Jan 11, 2013 1 Maintenance Commands PRTCONF(1M) 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. -p Displays information derived from the device tree pro- vided by the firmware (PROM) on SPARC platforms or the booting 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 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 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 Illumos Last change: Jan 11, 2013 2 Maintenance Commands PRTCONF(1M) hardware platform documentation contains more informa- tion 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.

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.
