NAME
       prtconf - print system configuration

SYNOPSIS
       /usr/sbin/prtconf [-V] | [-F] | [-m] | [-x] | [-bpv] | [-acdDPv]
	    [dev_path]

DESCRIPTION
       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.

       If  a  device  path  is specified on the command line for those command
       options that can take a device path, prtconf will only display informa‐
       tion 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 properties are "name", "compat‐
	     ible", "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 command 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 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.

       -m
	     Displays the amount system memory in megabytes.  This  flag  must
	     be used by itself.

       -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, informa‐
	     tion regarding pseudo devices is omitted.

       -v
	     Specifies verbose mode.

       -V
	     Displays platform-dependent PROM (on SPARC platforms) 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 applica‐
	     ble 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 configuration informa‐
		   tion 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 poten‐
       tially 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.

       On x86 platforms, the use of prtconf -vp provides a subset of  informa‐
       tion  from prtconf -v. The value of integer properties from prtconf -vp
       might require byte swapping for correct interpretation.
