1254219Scy# $FreeBSD: head/sys/conf/options 56424 2000-01-23 03:35:11Z bp $ 2254219Scy# 3254219Scy# On the handling of kernel options 4254219Scy# 5254219Scy# All kernel options should be listed in LINT, with suitable 6254219Scy# descriptions. Negative options (options that make some code not 7254219Scy# compile) should be commented out; LINT should compile as much code 8254219Scy# as possible. Try to structure option-using code so that a single 9254219Scy# option only switch code on, or only switch code off, to make it 10254219Scy# possible to have a full compile-test. If necessary, you can include 11254219Scy# "opt_lint.h" and check for COMPILING_LINT to get maximum code 12254219Scy# coverage. 13254219Scy# 14254219Scy# All new options shall also be listed in either "conf/options" or 15254219Scy# "<machine>/conf/options.<machine>". Options that affect a single 16254219Scy# source-file <xxx>.[c|s] should be directed into "opt_<xxx>.h", while 17254219Scy# options that affect multiple files should either go in 18254219Scy# "opt_global.h" if this is a kernel-wide option (used just about 19254219Scy# everywhere), or in "opt_<option-name-in-lower-case>.h" if it affect 20254219Scy# only some files. Note that the effect of listing only an option 21254219Scy# without a header-file-name in conf/options (and cousins) is that the 22254219Scy# last convention is followed. 23254219Scy# 24254219Scy# This handling scheme is not yet fully implemented. 25254219Scy# 26254219Scy# 27254219Scy# Format of this file: 28254219Scy# Option name filename 29254219Scy# 30254219Scy# If filename is missing, the default is 31254219Scy# opt_<name-of-option-in-lower-case>.h 32254219Scy 33254219Scy# Adaptec aic7xxx SCSI controller options 34254219ScyAHC_ALLOW_MEMIO opt_aic7xxx.h # Allow PCI devices to use memory 35254219Scy # mapped I/O 36254219Scy 37254219ScyAHC_TMODE_ENABLE opt_aic7xxx.h # Bitmap of units to enable 38254219Scy # targetmode operations. 39254219Scy 40254219ScyAHC_DUMP_EEPROM opt_aic7xxx.h # Dump the contents of our 41254219Scy # configuration prom. 42254219Scy 43254219ScyADW_ALLOW_MEMIO opt_adw.h # Allow PCI devices to use memory 44254219Scy # mapped I/O 45254219Scy 46254219Scy# Miscellaneous options. 47254219ScyCOMPAT_43 opt_compat.h 48254219ScyCOMPAT_SUNOS opt_compat.h 49254219ScyCOMPILING_LINT opt_lint.h 50254219ScyCY_PCI_FASTINTR 51254219ScyDDB 52254219ScyDDB_UNATTENDED opt_ddb.h 53254219ScyGDB_REMOTE_CHAT opt_ddb.h 54254219ScyDEVFS 55254219ScyHW_WDOG 56254219ScyKTRACE 57254219ScyMD5 58254219ScyMD_ROOT opt_md.h 59254219ScyMD_ROOT_SIZE opt_md.h 60254219ScyMFS_ROOT opt_mfs.h 61254219ScyMFS_ROOT_SIZE opt_mfs.h 62254219ScyNTIMECOUNTER opt_ntp.h 63254219ScyNSWAPDEV opt_swap.h 64254219ScyPPS_SYNC opt_ntp.h 65254219ScyQUOTA 66254219ScySPX_HACK 67254219ScySUIDDIR opt_suiddir.h 68254219ScySYSVMSG opt_sysvipc.h 69SYSVSEM opt_sysvipc.h 70SYSVSHM opt_sysvipc.h 71UCONSOLE 72ICMP_BANDLIM 73 74# POSIX kernel options 75P1003_1B opt_posix.h 76_KPOSIX_PRIORITY_SCHEDULING opt_posix.h 77_KPOSIX_VERSION opt_posix.h 78 79# Do we want the config file compiled into the kernel? 80INCLUDE_CONFIG_FILE opt_config.h 81 82# Options for static file systems.
