# $Id: options,v 1.67 1998/03/14 04:13:50 tegge Exp $ # # On the handling of kernel options # # All kernel options should be listed in LINT, with suitable # descriptions. Negative options (options that make some code not # compile) should be commented out; LINT should compile as much code # as possible. Try to structure option-using code so that a single # option only switch code on, or only switch code off, to make it # possible to have a full compile-test. If necessary, you can include # "opt_lint.h" and check for COMPILING_LINT to get maximum code # coverage. # # All new options shall also be listed in either "conf/options" or # "/conf/options.". Options that affect a single # source-file .[c|s] should be directed into "opt_.h", while # options that affect multiple files should either go in # "opt_global.h" if this is a kernel-wide option (used just about # everywhere), or in "opt_.h" if it affect # only some files. Note that the effect of listing only an option # without a header-file-name in conf/options (and cousins) is that the # last convention is followed. # # This handling scheme is not yet fully implemented. # # # Format of this file: # Option name filename # # If filename is missing, the default is # opt_.h # Miscellaneous options.
