1# $FreeBSD$ 2# 3# On the handling of kernel options 4# 5# All kernel options should be listed in LINT, with suitable 6# descriptions. Negative options (options that make some code not 7# compile) should be commented out; LINT should compile as much code 8# as possible. Try to structure option-using code so that a single 9# option only switch code on, or only switch code off, to make it 10# possible to have a full compile-test. If necessary, you can check 11# for COMPILING_LINT to get maximum code coverage. 12# 13# All new options shall also be listed in either "conf/options" or 14# "<machine>/conf/options.<machine>". Options that affect a single 15# source-file <xxx>.[c|s] should be directed into "opt_<xxx>.h", while 16# options that affect multiple files should either go in 17# "opt_global.h" if this is a kernel-wide option (used just about 18# everywhere), or in "opt_<option-name-in-lower-case>.h" if it affect 19# only some files. Note that the effect of listing only an option 20# without a header-file-name in conf/options (and cousins) is that the 21# last convention is followed. 22# 23# This handling scheme is not yet fully implemented. 24# 25# 26# Format of this file: 27# Option name filename 28# 29# If filename is missing, the default is 30# opt_<name-of-option-in-lower-case>.h 31 32# Adaptec Array Controller driver options 33AAC_COMPAT_LINUX opt_acc.h # Enable the linux ioctl interface 34 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_SEQUENCER opt_aic7xxx.h # Enable diagnostic sequencer code 53 54ADW_ALLOW_MEMIO opt_adw.h # Allow PCI devices to use memory 55 # mapped I/O 56 57# Miscellaneous options. 58BLEED 59COMPAT_43 opt_compat.h 60COMPAT_SUNOS opt_compat.h 61COMPILING_LINT opt_global.h 62CY_PCI_FASTINTR 63DDB 64DDB_UNATTENDED opt_ddb.h 65GDB_REMOTE_CHAT opt_ddb.h 66NODEVFS opt_devfs.h 67HW_WDOG 68KTRACE 69LIBICONV 70MD_ROOT opt_md.h 71MD_ROOT_SIZE opt_md.h 72NTIMECOUNTER opt_ntp.h 73NSWAPDEV opt_swap.h 74PPS_SYNC opt_ntp.h 75QUOTA 76SPX_HACK 77SUIDDIR opt_suiddir.h 78SYSVMSG opt_sysvipc.h 79SYSVSEM opt_sysvipc.h 80SYSVSHM opt_sysvipc.h 81SHMALL opt_sysvipc.h 82SHMMAX opt_sysvipc.h 83SHMMAXPGS opt_sysvipc.h 84SHMMIN opt_sysvipc.h 85SHMMNI opt_sysvipc.h 86SHMSEG opt_sysvipc.h 87SEMMAP opt_sysvipc.h 88SEMMNI opt_sysvipc.h 89SEMMNS opt_sysvipc.h 90SEMMNU opt_sysvipc.h 91SEMMSL opt_sysvipc.h 92SEMOPM opt_sysvipc.h 93SEMUME opt_sysvipc.h 94MSGMNB opt_sysvipc.h 95MSGMNI opt_sysvipc.h 96MSGSEG opt_sysvipc.h 97MSGSSZ opt_sysvipc.h 98MSGTQL opt_sysvipc.h 99UCONSOLE 100VFS_AIO 101 102# POSIX kernel options 103P1003_1B opt_posix.h 104_KPOSIX_PRIORITY_SCHEDULING opt_posix.h 105_KPOSIX_VERSION opt_posix.h 106 107# TrustedBSD and POSIX.1e Kernel Options 108CAPABILITIES opt_cap.h 109 110# Do we want the config file compiled into the kernel? 111INCLUDE_CONFIG_FILE opt_config.h 112 113# Options for static file systems.
