idconfig(1M)                  UNIX System V(i386)                  idconfig(1M)


NAME
      idconfig - produce a new kernel configuration

SYNOPSIS
      /etc/conf/bin/idconfig

DESCRIPTION
      The idconfig command takes as its input a collection of files specifying
      the configuration of the next UNIX System to be built.  A collection of
      output files for use by idmkunix is produced.

      The input files expected by idconfig are as follows:
            mdevice - Master device specifications
            sdevice - System device specifications
            mtune - Master parameter specifications
            stune - System parameter specifications
            mfsys - File system type master data
            sfsys - File system type system data
            sassign - Device Assignment File

      The output files produced by idconfig are as follows:
            conf.c - Kernel data structures and function definitions
            config.h - Kernel parameter and device definitions
            vector.c - Interrupt vector definitions
            direct - Listing of all driver components included in the build
            fsconf.c - File system type configuration data

      The command line options are as follows:

      -o directory   Output files will be created in the directory specified
                     rather than /etc/conf/cf.d .

      -i  directory  Input files that normally reside in /etc/conf/cf.d can be
                     found in the directory specified.

      -r  directory  The directory specified will be used as the ID "root"
                     directory rather than /etc/conf .

      -d  file       Use file name rather than sdevice for input.

      -t  file       Use file name rather than stune for input.

      -T  file       Use file name rather than mtune for input.

      -a  file       Use file name rather than sassign for input.

      -c  file       Redirect conf.c output to file name.

      -h  file       Redirect config.h output to file name.

      -v  file       Redirect vector.c output to file name.

      -p  file       Redirect direct output to file name.

      -D, -m, -s     These options are no longer supported.

      -#             Print debugging information.

      This version of UNIX supports multiple major numbers for drivers.
      idconfig generates additional constants (via defines) in the config.h
      file so that they can be used by the driver (as they will get referenced
      in the space.c file to generate appropriate data structures.  The
      information provided by these constants is how many major numbers were
      assigned to the device and what are their values.  The names of the
      constants are as follows:
            PRFXCMAJORX
            PRFXBMAJORX
      where PRFX stands for device prefix.  In case of a SCSI device, it would
      be a SCSI device.  The X stands for the list subscript, starting with
      subscript 0.

      In addition, the configuration file conf.c that initializes bdevsw[] and
      cdevsw[] tables will also add entries for each of the major numbers and,
      as such, the same driver entry points will be repeated for each one of
      the entries.

ERROR MESSAGES
      An exit value of zero indicates success.  If an error i was encountered,
      idconfig will exit with a non-zero value and report an error message.
      All error messages are designed to be self-explanatory.
