System Administration Commands | prtconf(1M) |
| prtconf - print system configuration |
SYNOPSIS
SPARC
|
| /usr/sbin/prtconf [-V] | [-F] | [-x] | [-vpPD] |
|
IA
|
| /usr/sbin/prtconf [-V] | [-x] | [-vpPD] |
|
|
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.
|
|
The following options are supported:
- -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 the console, frame buffer
device or a non-zero exit code. For example, if the console frame buffer on a SPARCstation 1 is cgthree in SBus slot #3, the command returns: /sbus@1,f80000000/cgthree@3,0. 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 IA 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 platforms) or booting system (on IA 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.

|
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 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 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.
