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 affects 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
