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 46TWA_DEBUG opt_twa.h 47 48# Debugging options. 49ALT_BREAK_TO_DEBUGGER opt_kdb.h 50BREAK_TO_DEBUGGER opt_kdb.h 51BUF_TRACKING opt_global.h 52DDB 53DDB_BUFR_SIZE opt_ddb.h 54DDB_CAPTURE_DEFAULTBUFSIZE opt_ddb.h 55DDB_CAPTURE_MAXBUFSIZE opt_ddb.h 56DDB_CTF opt_ddb.h 57DDB_NUMSYM opt_ddb.h 58EARLY_PRINTF opt_global.h 59FULL_BUF_TRACKING opt_global.h 60GDB 61KDB opt_global.h 62KDB_TRACE opt_kdb.h 63KDB_UNATTENDED opt_kdb.h 64KLD_DEBUG opt_kld.h 65NUM_CORE_FILES opt_global.h 66QUEUE_MACRO_DEBUG_TRACE opt_global.h 67QUEUE_MACRO_DEBUG_TRASH opt_global.h 68SYSCTL_DEBUG opt_sysctl.h 69TEXTDUMP_PREFERRED opt_ddb.h 70TEXTDUMP_VERBOSE opt_ddb.h 71TSLOG opt_global.h 72TSLOGSIZE opt_global.h 73 74# Miscellaneous options. 75ALQ 76ALTERA_SDCARD_FAST_SIM opt_altera_sdcard.h 77ATSE_CFI_HACK opt_cfi.h 78AUDIT opt_global.h 79BOOTHOWTO opt_global.h 80BOOTVERBOSE opt_global.h 81CALLOUT_PROFILING 82CAPABILITIES opt_capsicum.h 83CAPABILITY_MODE opt_capsicum.h 84CC_CDG opt_global.h 85CC_CHD opt_global.h 86CC_CUBIC opt_global.h 87CC_DEFAULT opt_cc.h 88CC_DCTCP opt_global.h 89CC_HD opt_global.h 90CC_HTCP opt_global.h 91CC_NEWRENO opt_global.h 92CC_VEGAS opt_global.h 93COMPAT_43 opt_global.h 94COMPAT_43TTY opt_global.h 95COMPAT_FREEBSD4 opt_global.h 96COMPAT_FREEBSD5 opt_global.h 97COMPAT_FREEBSD6 opt_global.h 98COMPAT_FREEBSD7 opt_global.h 99COMPAT_FREEBSD9 opt_global.h 100COMPAT_FREEBSD10 opt_global.h 101COMPAT_FREEBSD11 opt_global.h 102COMPAT_FREEBSD12 opt_global.h 103COMPAT_LINUXKPI opt_dontuse.h 104_COMPAT_LINUX32 opt_compat.h #
