1# $FreeBSD$ 2# 3# On the handling of kernel options 4# 5# All kernel options should be listed in NOTES, with suitable 6# descriptions. Negative options (options that make some code not 7# compile) should be commented out; LINT (generated from NOTES) should 8# compile as much code as possible. Try to structure option-using 9# code so that a single option only switch code on, or only switch 10# code off, to make it possible to have a full compile-test. If 11# necessary, you can check for COMPILING_LINT to get maximum code 12# coverage. 13# 14# All new options shall also be listed in either "conf/options" or 15# "conf/options.<machine>". Options that affect a single source-file 16# <xxx>.[c|s] should be directed into "opt_<xxx>.h", while options 17# that affect multiple files should either go in "opt_global.h" if 18# this is a kernel-wide option (used just about everywhere), or in 19# "opt_<option-name-in-lower-case>.h" if it affect only some files. 20# Note that the effect of listing only an option without a 21# header-file-name in conf/options (and cousins) is that the last 22# convention is followed. 23# 24# This handling scheme is not yet fully implemented. 25# 26# 27# Format of this file: 28# Option name filename 29# 30# If filename is missing, the default is 31# opt_<name-of-option-in-lower-case>.h 32 33# Adaptec Array Controller driver options 34AAC_DEBUG opt_aac.h # Debugging levels: 35 # 0 - quiet, only emit warnings 36 # 1 - noisy, emit major function 37 # points and things done 38 # 2 - extremely noisy, emit trace 39 # items in loops, etc. 40 41# Adaptec aic7xxx SCSI controller options 42AHC_ALLOW_MEMIO opt_aic7xxx.h # Allow PCI devices to use memory 43 # mapped I/O 44 45AHC_TMODE_ENABLE opt_aic7xxx.h # Bitmap of units to enable 46 # targetmode operations. 47 48AHC_DUMP_EEPROM opt_aic7xxx.h # Dump the contents of our 49 # configuration prom. 50 51AHC_DEBUG opt_aic7xxx.h # Compile in Aic7xxx Debugging code. 52 53AHC_DEBUG_OPTS opt_aic7xxx.h # Aic7xxx driver debugging options. 54 # See sys/dev/aic7xxx/aic7xxx.h 55 56AHC_REG_PRETTY_PRINT opt_aic7xxx.h # Print register bitfields in debug 57 # output.
