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# "<machine>/conf/options.<machine>". 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_COMPAT_LINUX opt_aac.h # Enable the linux ioctl interface 36 37AAC_DEBUG opt_aac.h # Debugging levels: 38 # 0 - quiet, only emit warnings 39 # 1 - noisy, emit major function 40 # points and things done 41 # 2 - extremely noisy, emit trace 42 # items in loops, etc. 43 44# Adaptec aic7xxx SCSI controller options 45AHC_ALLOW_MEMIO opt_aic7xxx.h # Allow PCI devices to use memory 46 # mapped I/O 47 48AHC_TMODE_ENABLE opt_aic7xxx.h # Bitmap of units to enable 49 # targetmode operations. 50 51AHC_DUMP_EEPROM opt_aic7xxx.h # Dump the contents of our 52 # configuration prom. 53 54AHC_DEBUG opt_aic7xxx.h # Compile in Aic7xxx Debugging code. 55 56AHC_DEBUG_OPTS opt_aic7xxx.h # Aic7xxx driver debugging options. 57 # See sys/dev/aic7xxx/aic7xxx.h 58 59AHC_REG_PRETTY_PRINT opt_aic7xxx.h # Print register bitfields in debug 60 # output.
