prtconf(1M)

NAME

     prtconf - print system configuration

SYNOPSIS

  SPARC
     /usr/sbin/prtconf  [-V] | [-F] | [-x] | [-vpPD]

  x86
     /usr/sbin/prtconf  [-V] | [-x] | [-vpPD]

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.

OPTIONS

     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 SPARCs-
           tation 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 pro-
           vided by the firmware (PROM) on SPARC platforms or the
           booting system on x86 platforms.The device tree infor-
           mation  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 x86 platforms) version informa-
           tion. 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.

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.
