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 include 11# "opt_lint.h" and 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# "<machine>/conf/options.<machine>". Options that affect a single 16# source-file <xxx>.[c|s] should be directed into "opt_<xxx>.h", while 17# options that affect multiple files should either go in 18# "opt_global.h" if this is a kernel-wide option (used just about 19# everywhere), or in "opt_<option-name-in-lower-case>.h" if it affect 20# only some files. Note that the effect of listing only an option 21# without a header-file-name in conf/options (and cousins) is that the 22# last 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 aic7xxx SCSI controller options 34AHC_ALLOW_MEMIO opt_aic7xxx.h # Allow PCI devices to use memory 35 # mapped I/O 36 37AHC_TMODE_ENABLE opt_aic7xxx.h # Bitmap of units to enable 38 # targetmode operations. 39 40AHC_DUMP_EEPROM opt_aic7xxx.h # Dump the contents of our 41 # configuration prom. 42 43ADW_ALLOW_MEMIO opt_adw.h # Allow PCI devices to use memory 44 # mapped I/O 45 46# Miscellaneous options. 47COMPAT_43 opt_compat.h 48COMPAT_SUNOS opt_compat.h 49COMPILING_LINT opt_lint.h 50CY_PCI_FASTINTR 51DDB 52DDB_UNATTENDED opt_ddb.h 53GDB_REMOTE_CHAT opt_ddb.h 54DEVFS 55HW_WDOG 56KTRACE 57MD_NSECT opt_md.h 58MD_ROOT opt_md.h 59MD_ROOT_SIZE opt_md.h 60MFS_ROOT opt_mfs.h 61MFS_ROOT_SIZE opt_mfs.h 62NTIMECOUNTER opt_ntp.h 63NSWAPDEV opt_swap.h 64PPS_SYNC opt_ntp.h 65QUOTA 66RANDOMDEV 67SPX_HACK 68SUIDDIR opt_suiddir.h 69SYSVMSG opt_sysvipc.h 70SYSVSEM opt_sysvipc.h 71SYSVSHM opt_sysvipc.h 72SHMALL opt_sysvipc.h 73SHMMAX opt_sysvipc.h 74SHMMAXPGS opt_sysvipc.h 75SHMMIN opt_sysvipc.h 76SHMMNI opt_sysvipc.h 77SHMSEG opt_sysvipc.h 78SHM_PHYS_BACKED opt_sysvipc.h 79SEMMAP opt_sysvipc.h 80SEMMNI opt_sysvipc.h 81SEMMNS opt_sysvipc.h 82SEMMNU opt_sysvipc.h 83SEMMSL opt_sysvipc.h 84SEMOPM opt_sysvipc.h 85SEMUME opt_sysvipc.h 86MSGMNB opt_sysvipc.h 87MSGMNI opt_sysvipc.h 88MSGSEG opt_sysvipc.h 89MSGSSZ opt_sysvipc.h 90MSGTQL opt_sysvipc.h 91UCONSOLE 92VFS_AIO 93 94# POSIX kernel options 95P1003_1B opt_posix.h 96_KPOSIX_PRIORITY_SCHEDULING opt_posix.h 97_KPOSIX_VERSION opt_posix.h 98 99# TrustedBSD and POSIX.1e Kernel Options 100CAPABILITIES opt_cap.h 101 102# Do we want the config file compiled into the kernel? 103INCLUDE_CONFIG_FILE opt_config.h 104 105# Options for static file systems.
