14 The prtconf command prints the system configuration information. The
15 output includes the total amount of memory, and the configuration of
16 system peripherals formatted as a device tree.
17 If a device path is specified on the command line for those command
20 options that can take a device path, prtconf will only display informa‐
21 tion for that device node.
22
24 The following options are supported:
25 -a Display all the ancestors device nodes, up to the root node of
27 the device tree, for the device specified on the command line.
28 -b Display the firmware device tree root properties for the purpose
31 of platform identification. These properties are "name", "compat‐
32 ible", "banner-name" and "model".
33 -c Display the device subtree rooted at the device node specified on
36 the command line, that is, display all the children of the device
37 node specified on the command line.
38 -d Display vendor ID and device ID for PCI and PCI Express devices,
41 in addition to the nodename.
42 -D For each system peripheral in the device tree, displays the name
45 of the device driver used to manage the peripheral.
46 -F A SPARC-only option. Returns the device path name of the console
49 frame buffer, if one exists. If there is no frame buffer, prtconf
50 returns a non-zero exit code. This flag must be used by itself.
51 It returns only the name of the console, frame buffer device or a
52 non-zero exit code. For example, if the console frame buffer on a
53 SUNW,Ultra-30 is ffb, the command returns: /SUNW,ffb@1e,0:ffb0.
54 This option could be used to create a symlink for /dev/fb to the
55 actual console device.
56 -p Displays information derived from the device tree provided by the
59 firmware (PROM) on SPARC platforms or the booting system on x86
60 platforms.The device tree information displayed using this option
61 is a snapshot of the initial configuration and may not accurately
62 reflect reconfiguration events that occur later.
63 -P Includes information about pseudo devices. By default, informa‐
66 tion regarding pseudo devices is omitted.
67 -v Specifies verbose mode.
70 -V Displays platform-dependent PROM (on SPARC platforms) or booting
73 system (on x86 platforms) version information. This flag must be
74 used by itself. The output is a string. The format of the string
75 is arbitrary and platform-dependent.
76 -x Reports if the firmware on this system is 64-bit ready. Some
79 existing platforms may need a firmware upgrade in order to run
80 the 64-bit kernel. If the operation is not applicable to this
81 platform or the firmware is already 64-bit ready, it exits
82 silently with a return code of zero. If the operation is applica‐
83 ble to this platform and the firmware is not 64-bit ready, it
84 displays a descriptive message on the standard output and exits
85 with a non-zero return code. The hardware platform documentation
86 contains more information about the platforms that may need a
87 firmware upgrade in order to run the 64-bit kernel.
88 This flag overrides all other flags and must be used by itself.
90
93 The following operands are supported:
94 dev_path The path to a target device minor node, device nexus node,
96 or device link for which device node configuration informa‐
97 tion is displayed
98
101 The following exit values are returned:
102 0 No error occurred.
104 non-zero With the -F option (SPARC only), a non-zero return value
107 means that the output device is not a frame buffer. With
108 the -x option, a non-zero return value means that the
109 firmware is not 64-bit ready. In all other cases, a non-
110 zero return value means that an error occurred.

136 The output of the prtconf command is highly dependent on the version of
137 the PROM installed in the system. The output will be affected in poten‐
138 tially all circumstances.
139 The driver not attached message means that no driver is currently
142 attached to that instance of the device. In general, drivers are loaded
143 and installed (and attached to hardware instances) on demand, and when
144 needed, and may be uninstalled and unloaded when the device is not in
145 use.
146 On x86 platforms, the use of prtconf -vp provides a subset of informa‐
149 tion from prtconf -v. The value of integer properties from prtconf -vp
150 might require byte swapping for correct interpretation.
