Negative options (options that make some code not # compile) should be commented out; LINT (generated from NOTES) 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 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 affects 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 AAC_DEBUG opt_aac.h AACRAID_DEBUG opt_aacraid.h AHC_ALLOW_MEMIO opt_aic7xxx.h AHC_TMODE_ENABLE opt_aic7xxx.h AHC_DUMP_EEPROM opt_aic7xxx.h AHC_DEBUG opt_aic7xxx.h AHC_DEBUG_OPTS opt_aic7xxx.h AHC_REG_PRETTY_PRINT opt_aic7xxx.h AHD_DEBUG opt_aic79xx.h AHD_DEBUG_OPTS opt_aic79xx.h AHD_TMODE_ENABLE opt_aic79xx.h AHD_REG_PRETTY_PRINT opt_aic79xx.h ADW_ALLOW_MEMIO opt_adw.h TWA_DEBUG opt_twa.h TWA_FLASH_FIRMWARE opt_twa.h # Debugging options.
