1# $FreeBSD: head/sys/conf/options 66502 2000-10-01 08:17:47Z iwasaki $ 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 aic7xxx SCSI controller options 33AHC_ALLOW_MEMIO opt_aic7xxx.h # Allow PCI devices to use memory 34 # mapped I/O 35 36AHC_TMODE_ENABLE opt_aic7xxx.h # Bitmap of units to enable 37 # targetmode operations. 38 39AHC_DUMP_EEPROM opt_aic7xxx.h # Dump the contents of our 40 # configuration prom. 41 42ADW_ALLOW_MEMIO opt_adw.h # Allow PCI devices to use memory 43 # mapped I/O 44 45# Miscellaneous options. 46COMPAT_43 opt_compat.h 47COMPAT_SUNOS opt_compat.h 48COMPILING_LINT opt_global.h 49CY_PCI_FASTINTR 50DDB 51DDB_UNATTENDED opt_ddb.h 52GDB_REMOTE_CHAT opt_ddb.h 53DEVFS 54HW_WDOG 55KTRACE 56MD_NSECT opt_md.h 57MD_ROOT opt_md.h 58MD_ROOT_SIZE opt_md.h 59MFS_ROOT opt_mfs.h 60MFS_ROOT_SIZE opt_mfs.h 61NTIMECOUNTER opt_ntp.h 62NSWAPDEV opt_swap.h 63PPS_SYNC opt_ntp.h 64QUOTA 65SPX_HACK 66SUIDDIR opt_suiddir.h 67SYSVMSG opt_sysvipc.h 68SYSVSEM opt_sysvipc.h 69SYSVSHM opt_sysvipc.h 70SHMALL opt_sysvipc.h 71SHMMAX opt_sysvipc.h 72SHMMAXPGS opt_sysvipc.h 73SHMMIN opt_sysvipc.h 74SHMMNI opt_sysvipc.h 75SHMSEG opt_sysvipc.h 76SEMMAP opt_sysvipc.h 77SEMMNI opt_sysvipc.h 78SEMMNS opt_sysvipc.h 79SEMMNU opt_sysvipc.h 80SEMMSL opt_sysvipc.h 81SEMOPM opt_sysvipc.h 82SEMUME opt_sysvipc.h 83MSGMNB opt_sysvipc.h 84MSGMNI opt_sysvipc.h 85MSGSEG opt_sysvipc.h 86MSGSSZ opt_sysvipc.h 87MSGTQL opt_sysvipc.h 88UCONSOLE 89VFS_AIO 90 91# POSIX kernel options 92P1003_1B opt_posix.h 93_KPOSIX_PRIORITY_SCHEDULING opt_posix.h 94_KPOSIX_VERSION opt_posix.h 95 96# TrustedBSD and POSIX.1e Kernel Options 97CAPABILITIES opt_cap.h 98 99# Do we want the config file compiled into the kernel? 100INCLUDE_CONFIG_FILE opt_config.h 101 102# Options for static file systems.
