    3 #        On the handling of kernel options
    4 #
    5 # All kernel options should be listed in NOTES, with suitable
    6 # descriptions.  Negative options (options that make some code not
    7 # compile) should be commented out; LINT (generated from NOTES) should
    8 # compile as much code as possible.  Try to structure option-using
    9 # code so that a single option only switch code on, or only switch
   10 # code off, to make it possible to have a full compile-test.  If
   11 # necessary, you can check for COMPILING_LINT to get maximum code
   12 # coverage.
   13 #
   14 # All new options shall also be listed in either "conf/options" or
   15 # "conf/options.<machine>".  Options that affect a single source-file
   16 # <xxx>.[c|s] should be directed into "opt_<xxx>.h", while options
   17 # that affect multiple files should either go in "opt_global.h" if
   18 # this is a kernel-wide option (used just about everywhere), or in
   19 # "opt_<option-name-in-lower-case>.h" if it affect only some files.
   20 # Note that the effect of listing only an option without a
   21 # header-file-name in conf/options (and cousins) is that the last
   22 # convention is followed.
   23 #
   24 # This handling scheme is not yet fully implemented.
   25 #
   26 #
   27 # Format of this file:
   28 # Option name   filename
   29 #
   30 # If filename is missing, the default is
   31 # opt_<name-of-option-in-lower-case>.h
