prtconf


NAME
     prtconf - print system configuration

SYNOPSIS
     /usr/sbin/prtconf  [-V] | [-F] | [-x] |  [-bpv]  |  [-acDPv]
     [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 speci-
              fied 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  specified  on  the  command  line,  that  is,
              display all the children of the device node  speci-
              fied on the command line.



     -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.



     -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,  information  regarding  pseudo devices is
              omitted.



     -v       Specifies verbose mode.



     -V       Displays platform-dependent PROM  (on  SPARC  plat-
              forms) 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
              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.

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  confi-
                             guration 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 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.
