1# $FreeBSD: head/sys/conf/options 182222 2008-08-27 01:26:14Z imp $ 2# 3# On the handling of kernel options 4# 5# All kernel options should be listed in NOTES, with suitable 6# descriptions. Negative options (options that make some code not 7# compile) should be commented out; LINT (generated from NOTES) should 8# compile as much code as possible. Try to structure option-using 9# code so that a single option only switch code on, or only switch 10# code off, to make it possible to have a full compile-test. If 11# necessary, you can 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# "conf/options.<machine>". Options that affect a single source-file 16# <xxx>.[c|s] should be directed into "opt_<xxx>.h", while options 17# that affect multiple files should either go in "opt_global.h" if 18# this is a kernel-wide option (used just about everywhere), or in 19# "opt_<option-name-in-lower-case>.h" if it affects only some files. 20# Note that the effect of listing only an option without a 21# header-file-name in conf/options (and cousins) is that the last 22# 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 33AAC_DEBUG opt_aac.h 34AHC_ALLOW_MEMIO opt_aic7xxx.h 35AHC_TMODE_ENABLE opt_aic7xxx.h 36AHC_DUMP_EEPROM opt_aic7xxx.h 37AHC_DEBUG opt_aic7xxx.h 38AHC_DEBUG_OPTS opt_aic7xxx.h 39AHC_REG_PRETTY_PRINT opt_aic7xxx.h 40AHD_DEBUG opt_aic79xx.h 41AHD_DEBUG_OPTS opt_aic79xx.h 42AHD_TMODE_ENABLE opt_aic79xx.h 43AHD_REG_PRETTY_PRINT opt_aic79xx.h 44ADW_ALLOW_MEMIO opt_adw.h 45 46TWA_DEBUG opt_twa.h 47TWA_FLASH_FIRMWARE opt_twa.h 48 49# Debugging options. 50DDB 51DDB_BUFR_SIZE opt_ddb.h 52DDB_CAPTURE_DEFAULTBUFSIZE opt_ddb.h 53DDB_CAPTURE_MAXBUFSIZE opt_ddb.h 54DDB_CTF opt_ddb.h 55DDB_NUMSYM opt_ddb.h 56GDB 57KDB opt_global.h 58KDB_TRACE opt_kdb.h 59KDB_UNATTENDED opt_kdb.h 60SYSCTL_DEBUG opt_sysctl.h 61 62NO_SYSCTL_DESCR opt_global.h 63 64# Miscellaneous options. 65ADAPTIVE_SX 66ALQ 67AUDIT opt_global.h 68CODA_COMPAT_5 opt_coda.h 69COMPAT_43 opt_compat.h 70COMPAT_43TTY opt_compat.h 71COMPAT_FREEBSD4 opt_compat.h 72COMPAT_FREEBSD5 opt_compat.h 73COMPAT_FREEBSD6 opt_compat.h 74COMPAT_FREEBSD7 opt_compat.h 75COMPILING_LINT opt_global.h 76CY_PCI_FASTINTR 77DIRECTIO 78FULL_PREEMPTION opt_sched.h 79IPI_PREEMPTION opt_sched.h 80GEOM_AES opt_geom.h 81GEOM_BDE opt_geom.h 82GEOM_BSD opt_geom.h 83GEOM_CACHE opt_geom.h 84GEOM_CONCAT opt_geom.h 85GEOM_ELI opt_geom.h 86GEOM_FOX opt_geom.h 87GEOM_GATE opt_geom.h 88GEOM_JOURNAL opt_geom.h 89GEOM_LABEL opt_geom.h 90GEOM_LINUX_LVM opt_geom.h 91GEOM_MBR opt_geom.h 92GEOM_MIRROR opt_geom.h 93GEOM_MULTIPATH opt_geom.h 94GEOM_NOP opt_geom.h 95GEOM_PART_APM opt_geom.h 96GEOM_PART_BSD opt_geom.h 97GEOM_PART_GPT opt_geom.h 98GEOM_PART_MBR opt_geom.h 99GEOM_PART_PC98 opt_geom.h 100GEOM_PART_VTOC8 opt_geom.h 101GEOM_PC98 opt_geom.h 102GEOM_RAID3 opt_geom.h 103GEOM_SHSEC opt_geom.h 104GEOM_STRIPE opt_geom.h 105GEOM_SUNLABEL opt_geom.h 106GEOM_UZIP opt_geom.h 107GEOM_VIRSTOR opt_geom.h 108GEOM_VOL opt_geom.h 109GEOM_ZERO opt_geom.h 110KDTRACE_HOOKS opt_kdtrace.h 111KSTACK_MAX_PAGES 112KSTACK_PAGES 113KTRACE 114KTRACE_REQUEST_POOL opt_ktrace.h 115LIBICONV 116MAC 117MAC_BIBA opt_dontuse.h 118MAC_BSDEXTENDED opt_dontuse.h 119MAC_IFOFF opt_dontuse.h 120MAC_LOMAC opt_dontuse.h 121MAC_MLS opt_dontuse.h 122MAC_NONE opt_dontuse.h 123MAC_PARTITION opt_dontuse.h 124MAC_PORTACL opt_dontuse.h 125MAC_SEEOTHERUIDS opt_dontuse.h 126MAC_STATIC opt_mac.h 127MAC_STUB opt_dontuse.h 128MAC_TEST opt_dontuse.h 129MD_ROOT opt_md.h 130MD_ROOT_SIZE opt_md.h 131MFI_DEBUG opt_mfi.h 132MFI_DECODE_LOG opt_mfi.h 133MPROF_BUFFERS opt_mprof.h 134MPROF_HASH_SIZE opt_mprof.h 135NO_ADAPTIVE_MUTEXES opt_adaptive_mutexes.h 136NO_ADAPTIVE_RWLOCKS 137NSWBUF_MIN opt_swap.h 138MBUF_PACKET_ZONE_DISABLE opt_global.h 139PANIC_REBOOT_WAIT_TIME opt_panic.h 140PPC_DEBUG opt_ppc.h 141PPC_PROBE_CHIPSET opt_ppc.h 142PPS_SYNC opt_ntp.h 143PREEMPTION opt_sched.h 144QUOTA 145SCHED_4BSD opt_sched.h 146SCHED_STATS opt_sched.h 147SCHED_ULE opt_sched.h 148SHOW_BUSYBUFS 149SLEEPQUEUE_PROFILING 150SLHCI_DEBUG opt_slhci.h 151SPX_HACK 152STACK opt_stack.h 153SUIDDIR 154MSGMNB opt_sysvipc.h 155MSGMNI opt_sysvipc.h 156MSGSEG opt_sysvipc.h 157MSGSSZ opt_sysvipc.h 158MSGTQL opt_sysvipc.h 159SEMMAP opt_sysvipc.h 160SEMMNI opt_sysvipc.h 161SEMMNS opt_sysvipc.h 162SEMMNU opt_sysvipc.h 163SEMMSL opt_sysvipc.h 164SEMOPM opt_sysvipc.h 165SEMUME opt_sysvipc.h 166SHMALL opt_sysvipc.h 167SHMMAX opt_sysvipc.h 168SHMMAXPGS opt_sysvipc.h 169SHMMIN opt_sysvipc.h 170SHMMNI opt_sysvipc.h 171SHMSEG opt_sysvipc.h 172SYSVMSG opt_sysvipc.h 173SYSVSEM opt_sysvipc.h 174SYSVSHM opt_sysvipc.h 175SW_WATCHDOG opt_watchdog.h 176TURNSTILE_PROFILING 177VFS_AIO 178VERBOSE_SYSINIT opt_global.h 179WLCACHE opt_wavelan.h 180WLDEBUG opt_wavelan.h 181 182# POSIX kernel options 183P1003_1B_MQUEUE opt_posix.h 184P1003_1B_SEMAPHORES opt_posix.h 185_KPOSIX_PRIORITY_SCHEDULING opt_posix.h 186 187# Do we want the config file compiled into the kernel? 188INCLUDE_CONFIG_FILE opt_config.h 189 190# Options for static filesystems.
