      3 # GENERIC machine description file
      4 # 
      5 # This machine description file is used to generate the default NetBSD
      6 # kernel.  The generic kernel does not include all options, subsystems
      7 # and device drivers, but should be useful for most applications.
      8 #
      9 # The machine description file can be customised for your specific
     10 # machine to reduce the kernel size and improve its performance.
     11 #
     12 # For further information on compiling NetBSD kernels, see the config(8)
     13 # man page.
     14 #
     15 # For further information on hardware support for this architecture, see
     16 # the intro(4) man page.  For further information about kernel options
     17 # for this architecture, see the options(4) man page.  For an explanation
     18 # of each device driver in this file see the section 4 man page for the
     19 # device.

     55 
     56 ## Root device configuration: change the ?'s if you are going to use a
     57 ## nonstandard root partition (other than where the kernel is booted from)
     58 ## and/or nonstandard root type (not ffs or nfs).  Normally this can be

     70 
     71 ## Collect statistics on kernel malloc's and free's.  This does have a

    105 
    106 ## The DDB in-kernel debugger runs at panic (unless DDB_ONPANIC=0), or at
    107 ## serial console break or keyboard reset, where the PROM would normally
    108 ## intercept.  DDB_HISTORY_SIZE adds up/down arrow command history.

    113 
    114 ## You may also use gdb, on another computer connected to this machine over
    115 ## a serial port.  Both KGDB_DEV and KGDB_DEVRATE should be specified;

    117 ## KGDB is not supported for now.
    118 #options 	KGDB			# support for kernel gdb

    124 
    125 #makeoptions	DEBUG="-g"
    126 
    127 ## Adds code to the kernel that does internal consistency checks, and will
    128 ## cause the kernel to panic if corruption of internal data structures
    129 ## is detected.
    130 #options 	DIAGNOSTIC	# extra kernel sanity checking

    137 ## Warning, these may compile large string tables into the kernel!
    138 #options 	SCSIVERBOSE	# human readable SCSI error messages
    139 #options 	USBVERBOSE	# verbose USB device autoconfig messages
    140 
    141 ## `INSECURE' turns off the kernel security level (securelevel = 0 always).
    142 ## This allows writing to /dev/mem, loading kernel modules while multi-user,
    143 ## and other insecurities good only for development work.  Do not use this
    144 ## option on a production machine.
    145 #options 	INSECURE
    146 
    147 ## `FDSCRIPTS' allows non-readable but executable scripts by providing a
    148 ## pre-opened opaque file to the script interpreter.  `SETUIDSCRIPTS',
    149 ## which implies FDSCRIPTS, allows scripts to be set-user-id using the same
    150 ## opaque file mechanism.  Perl calls this "secure setuid scripts."
