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 affects 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 33AAC_DEBUG opt_aac.h 34AACRAID_DEBUG opt_aacraid.h 35AHC_ALLOW_MEMIO opt_aic7xxx.h 36AHC_TMODE_ENABLE opt_aic7xxx.h 37AHC_DUMP_EEPROM opt_aic7xxx.h 38AHC_DEBUG opt_aic7xxx.h 39AHC_DEBUG_OPTS opt_aic7xxx.h 40AHC_REG_PRETTY_PRINT opt_aic7xxx.h 41AHD_DEBUG opt_aic79xx.h 42AHD_DEBUG_OPTS opt_aic79xx.h 43AHD_TMODE_ENABLE opt_aic79xx.h 44AHD_REG_PRETTY_PRINT opt_aic79xx.h 45 46# Debugging options. 47ALT_BREAK_TO_DEBUGGER opt_kdb.h 48BREAK_TO_DEBUGGER opt_kdb.h 49BUF_TRACKING opt_global.h 50DDB 51DDB_BUFR_SIZE opt_ddb.h 52DDB_CAPTURE_DEFAULTBUFSIZE opt_ddb.h 53DDB_CAPTURE_MAXBUFSIZE opt_ddb.h 54DDB_CTF opt_ddb.h 55DDB_NUMSYM opt_ddb.h 56EARLY_PRINTF opt_global.h 57FULL_BUF_TRACKING opt_global.h 58GDB 59KDB opt_global.h 60KDB_TRACE opt_kdb.h 61KDB_UNATTENDED opt_kdb.h 62KLD_DEBUG opt_kld.h 63NUM_CORE_FILES opt_global.h 64QUEUE_MACRO_DEBUG_TRACE opt_global.h 65QUEUE_MACRO_DEBUG_TRASH opt_global.h 66SYSCTL_DEBUG opt_sysctl.h 67TEXTDUMP_PREFERRED opt_ddb.h 68TEXTDUMP_VERBOSE opt_ddb.h 69TSLOG opt_global.h 70TSLOGSIZE opt_global.h 71 72# Miscellaneous options. 73ALQ 74ALTERA_SDCARD_FAST_SIM opt_altera_sdcard.h 75ATSE_CFI_HACK opt_cfi.h 76AUDIT opt_global.h 77BOOTHOWTO opt_global.h 78BOOTVERBOSE opt_global.h 79CALLOUT_PROFILING 80CAPABILITIES opt_capsicum.h 81CAPABILITY_MODE opt_capsicum.h 82CC_CDG opt_global.h 83CC_CHD opt_global.h 84CC_CUBIC opt_global.h 85CC_DEFAULT opt_cc.h 86CC_DCTCP opt_global.h 87CC_HD opt_global.h 88CC_HTCP opt_global.h 89CC_NEWRENO opt_global.h 90CC_VEGAS opt_global.h 91COMPAT_43 opt_global.h 92COMPAT_43TTY opt_global.h 93COMPAT_FREEBSD4 opt_global.h 94COMPAT_FREEBSD5 opt_global.h 95COMPAT_FREEBSD6 opt_global.h 96COMPAT_FREEBSD7 opt_global.h 97COMPAT_FREEBSD9 opt_global.h 98COMPAT_FREEBSD10 opt_global.h 99COMPAT_FREEBSD11 opt_global.h 100COMPAT_FREEBSD12 opt_global.h 101COMPAT_FREEBSD13 opt_global.h 102COMPAT_LINUXKPI opt_dontuse.h 103_COMPAT_LINUX32 opt_compat.h #
