prtconf(1M)		System Administration Commands		   prtconf(1M)

NAME
       prtconf - print system configuration

SYNOPSIS
       /usr/sbin/prtconf   [-V] |  [-F] |  [-x] |  [-bpv]
	|  [-acDPv] [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", "compatible", "banner-name" and "model".

       -c	    Display the device subtree rooted at the device node spec‐
		    ified on the command line, that is, display all the	 chil‐
		    dren of the device node specified on the command line.

       -D	    For	 each  system  peripheral in the device tree, displays
		    the name of the device driver used to manage  the  periph‐
		    eral.

       -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 provided
		    by the firmware (PROM) on SPARC platforms or  the  booting
		    system  on	x86 platforms.The device tree information dis‐
		    played using this option is a snapshot of the initial con‐
		    figuration	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  information.
		    This  flag must be used by itself. The output is a string.
		    The format of the string is arbitrary and  platform-depen‐
		    dent.

       -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 descrip‐
		    tive message on the standard output and exits with a  non-
		    zero return code. The hardware platform documentation con‐
		    tains 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  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.

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.
