Negative options (options that make some code not 8# compile) should be commented out; LINT should compile as much code 9# as possible. Try to structure option-using code so that a single 10# option only switch code on, or only switch code off, to make it 11# possible to have a full compile-test. If necessary, you can include 12# "opt_lint.h" and check for COMPILING_LINT to get maximum code 13# coverage. 14# 15# All new options shall also be listed in either "conf/options" or 16# "<platform>/conf/options.<platform>". Options that affect a single 17# source-file <xxx>.[c|s] should be directed into "opt_<xxx>.h", while 18# options that affect multiple files should either go in 19# "opt_global.h" if this is a kernel-wide option (used just about 20# everywhere), or in "opt_<option-name-in-lower-case>.h" if it affect 21# only some files. Note that the effect of listing only an option 22# without a header-file-name in conf/options (and cousins) is that the 23# last convention is followed. 24# 25# This handling scheme is not yet fully implemented. 26# 27# 28# Format of this file: 29# Option name filename 30# 31# If filename is missing, the default is 32# opt_<name-of-option-in-lower-case>.h 33 34# Adaptec Array Controller driver options 35AAC_DEBUG opt_aac.h # Debugging levels: 36 # 0 - quiet, only emit warnings 37 # 1 - noisy, emit major function 38 # points and things done 39 # 2 - extremely noisy, emit trace 40 # items in loops, etc. 41 42# Adaptec aic7xxx SCSI controller options 43AHC_ALLOW_MEMIO opt_aic7xxx.h # Allow PCI devices to use memory 44 # mapped I/O 45 46AHC_TMODE_ENABLE opt_aic7xxx.h # Bitmap of units to enable 47 # targetmode operations. 48 49AHC_DUMP_EEPROM opt_aic7xxx.h # Dump the contents of our 50 # configuration prom. 51 52AHC_DEBUG opt_aic7xxx.h # Compile in Aic7xxx Debugging code. 53 54AHC_DEBUG_OPTS opt_aic7xxx.h # Aic7xxx driver debugging options. 55 # See sys/dev/aic7xxx/aic7xxx.h 56 57AHC_REG_PRETTY_PRINT opt_aic7xxx.h # Print register bitfields in debug 58 # output.
