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 57MD5 58MFS_ROOT opt_mfs.h 59MFS_ROOT_SIZE opt_mfs.h 60NTIMECOUNTER opt_ntp.h 61NSWAPDEV opt_swap.h 62PPS_SYNC opt_ntp.h 63QUOTA 64SPX_HACK 65SUIDDIR opt_suiddir.h 66SYSVMSG opt_sysvipc.h 67SYSVSEM opt_sysvipc.h 68SYSVSHM opt_sysvipc.h 69UCONSOLE 70ICMP_BANDLIM 71 72# POSIX kernel options 73P1003_1B opt_posix.h 74_KPOSIX_PRIORITY_SCHEDULING opt_posix.h 75_KPOSIX_VERSION opt_posix.h 76 77# Do we want the config file compiled into the kernel? 78INCLUDE_CONFIG_FILE opt_config.h 79 80# Options for static file systems.
