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