autoconf(8)                                                     autoconf(8)

NAME
     autoconf - display hardware configuration

SYNOPSIS
     autoconf -l [-v]

     autoconf -p

     autoconf -a [-v]

     autoconf -d devname

     autoconf -f

DESCRIPTION
     autoconf displays information about the various hardware components of
     the system and the current state of the associated software.

     Hardware configuration information is maintained by the kernel in a
     set of data structures resembling a tree. Each data structure or node
     represents a single hardware device. The nodes are connected together
     in a way that usefully represents the way the hardware is connected
     together. Controllers are attached to buses, and devices are connected
     to controllers.

OPTIONS
     -l   Display hardware configuration. Each line describes a node in the
          kernel autoconf tree. Indentation is used to indicate where in
          the tree the node appears. The root node is leftmost. The branch
          and leaf nodes are displayed progressively to the right. Each
          line contains the device name and a descriptive string from the
          node.

     -v   The verbose, -v, flag adds node type and state information to the
          beginning of each line. The state information is described by
          several letters. The letter F indicates that the device was found
          by the software. E indicates that the device has been enabled for
          use. B indicates that the device is broken and may not work reli-
          ably if still enabled.

          The following is an example of the output lines that can occur
          when calling autoconf -lv:

          DEV:FE  O :D  RX :             ios0/sdisk040 MP14 -- MP14

          "O" stands for "open", which means that one of the disk parti-
          tions is currently in use. If there is an "S" (suspended) here
          instead of an "O", the device cannot be used at this time.

     -p   Display hardware configuration in an easily parsable format. This
          option is equivalent to the -l option except that fields in each
          line of output are separated by "|" characters.

autoconf(8)                                                     autoconf(8)

     -a   Display all information about the autoconf node, such as tree
          connectivity, memory requirements, and any hardware specific
          information (i.e. SCSI inquiry name). This format is primarily
          useful for field engineers.

     -d devname
          Outputs the major number and minor number of the device specified
          in devname. The device name must be specified as follows, for
          example: ios0/sdisk000s0 or ios0/stape000h.

     -f   Display the inquiry data (device name + firmware revisions) of
          all SCSI devices (disks, tape drives etc.).

DIAGNOSTICS
     Exit status is normally 0. If an error occurs, exit status is 1.

NOTES
     Some device drivers may not use the autoconf kernel facilities. auto-
     conf will not produce any output for these devices.
