1# 2# On the handling of kernel options 3# 4# All kernel options should be listed in NOTES, with suitable 5# descriptions. Negative options (options that make some code not 6# compile) should be commented out; LINT (generated from NOTES) should 7# compile as much code as possible. Try to structure option-using 8# code so that a single option only switch code on, or only switch 9# code off, to make it possible to have a full compile-test. If 10# necessary, you can check for COMPILING_LINT to get maximum code 11# coverage. 12# 13# All new options shall also be listed in either "conf/options" or 14# "conf/options.<machine>". Options that affect a single source-file 15# <xxx>.[c|s] should be directed into "opt_<xxx>.h", while options 16# that affect multiple files should either go in "opt_global.h" if 17# this is a kernel-wide option (used just about everywhere), or in 18# "opt_<option-name-in-lower-case>.h" if it affects only some files. 19# Note that the effect of listing only an option without a 20# header-file-name in conf/options (and cousins) is that the last 21# convention is followed. 22# 23# This handling scheme is not yet fully implemented. 24# 25# 26# Format of this file: 27# Option name filename 28# 29# If filename is missing, the default is 30# opt_<name-of-option-in-lower-case>.h 31 32AAC_DEBUG opt_aac.h 33AACRAID_DEBUG opt_aacraid.h 34AHC_ALLOW_MEMIO opt_aic7xxx.h
