Negative options (options that make some code not 74718c85aSDima Dorfman# compile) should be commented out; LINT (generated from NOTES) should 84718c85aSDima Dorfman# compile as much code as possible. Try to structure option-using 94718c85aSDima Dorfman# code so that a single option only switch code on, or only switch 104718c85aSDima Dorfman# code off, to make it possible to have a full compile-test. If 114718c85aSDima Dorfman# necessary, you can check for COMPILING_LINT to get maximum code 124718c85aSDima Dorfman# coverage. 1394db1b81SEivind Eklund# 1494db1b81SEivind Eklund# All new options shall also be listed in either "conf/options" or 154718c85aSDima Dorfman# "conf/options.<machine>". Options that affect a single source-file 164718c85aSDima Dorfman# <xxx>.[c|s] should be directed into "opt_<xxx>.h", while options 174718c85aSDima Dorfman# that affect multiple files should either go in "opt_global.h" if 184718c85aSDima Dorfman# this is a kernel-wide option (used just about everywhere), or in 19786da2bbSMatt Jacob# "opt_<option-name-in-lower-case>.h" if it affects only some files. 204718c85aSDima Dorfman# Note that the effect of listing only an option without a 214718c85aSDima Dorfman# header-file-name in conf/options (and cousins) is that the last 224718c85aSDima Dorfman# convention is followed. 2394db1b81SEivind Eklund# 2494db1b81SEivind Eklund# This handling scheme is not yet fully implemented. 2594db1b81SEivind Eklund# 2694db1b81SEivind Eklund# 2794db1b81SEivind Eklund# Format of this file: 284bd49128SPeter Wemm# Option name filename 2994db1b81SEivind Eklund# 3094db1b81SEivind Eklund# If filename is missing, the default is 3194db1b81SEivind Eklund# opt_<name-of-option-in-lower-case>.h 3281fc841cSBruce Evans 33662d3818SScott LongAAC_DEBUG opt_aac.h 34dce93cd0SAchim LeubnerAACRAID_DEBUG opt_aacraid.h 35662d3818SScott LongAHC_ALLOW_MEMIO opt_aic7xxx.h 36662d3818SScott LongAHC_TMODE_ENABLE opt_aic7xxx.h 37662d3818SScott LongAHC_DUMP_EEPROM opt_aic7xxx.h 38662d3818SScott LongAHC_DEBUG opt_aic7xxx.h 39662d3818SScott LongAHC_DEBUG_OPTS opt_aic7xxx.h 40662d3818SScott LongAHC_REG_PRETTY_PRINT opt_aic7xxx.h 41662d3818SScott LongAHD_DEBUG opt_aic79xx.h 42662d3818SScott LongAHD_DEBUG_OPTS opt_aic79xx.h 43662d3818SScott LongAHD_TMODE_ENABLE opt_aic79xx.h 44662d3818SScott LongAHD_REG_PRETTY_PRINT opt_aic79xx.h 45662d3818SScott LongADW_ALLOW_MEMIO opt_adw.h 46528784edSJustin T.
