1# $FreeBSD$ 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 62# Miscellaneous options. 63ADAPTIVE_SX 64ALQ 65AUDIT opt_global.h 66CODA_COMPAT_5 opt_coda.h 67COMPAT_43 opt_compat.h 68COMPAT_43TTY opt_compat.h 69COMPAT_FREEBSD4 opt_compat.h 70COMPAT_FREEBSD5 opt_compat.h 71COMPAT_FREEBSD6 opt_compat.h 72COMPAT_FREEBSD7 opt_compat.h 73COMPILING_LINT opt_global.h 74CY_PCI_FASTINTR 75DIRECTIO 76FULL_PREEMPTION opt_sched.h 77IPI_PREEMPTION opt_sched.h 78GEOM_AES opt_geom.h 79GEOM_BDE opt_geom.h 80GEOM_BSD opt_geom.h 81GEOM_CACHE opt_geom.h 82GEOM_CONCAT opt_geom.h 83GEOM_ELI opt_geom.h 84GEOM_FOX opt_geom.h 85GEOM_GATE opt_geom.h 86GEOM_JOURNAL opt_geom.h 87GEOM_LABEL opt_geom.h 88GEOM_LINUX_LVM opt_geom.h 89GEOM_MBR opt_geom.h 90GEOM_MIRROR opt_geom.h 91GEOM_MULTIPATH opt_geom.h 92GEOM_NOP opt_geom.h 93GEOM_PART_APM opt_geom.h 94GEOM_PART_BSD opt_geom.h 95GEOM_PART_EBR opt_geom.h 96GEOM_PART_EBR_COMPAT 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 137NO_SYSCTL_DESCR opt_global.h 138NSWBUF_MIN opt_swap.h 139MBUF_PACKET_ZONE_DISABLE opt_global.h 140PANIC_REBOOT_WAIT_TIME opt_panic.h 141PPC_DEBUG opt_ppc.h 142PPC_PROBE_CHIPSET opt_ppc.h 143PPS_SYNC opt_ntp.h 144PREEMPTION opt_sched.h 145QUOTA 146SCHED_4BSD opt_sched.h 147SCHED_STATS opt_sched.h 148SCHED_ULE opt_sched.h 149SHOW_BUSYBUFS 150SLEEPQUEUE_PROFILING 151SLHCI_DEBUG opt_slhci.h 152SPX_HACK 153STACK opt_stack.h 154SUIDDIR 155MSGMNB opt_sysvipc.h 156MSGMNI opt_sysvipc.h 157MSGSEG opt_sysvipc.h 158MSGSSZ opt_sysvipc.h 159MSGTQL opt_sysvipc.h 160SEMMAP opt_sysvipc.h 161SEMMNI opt_sysvipc.h 162SEMMNS opt_sysvipc.h 163SEMMNU opt_sysvipc.h 164SEMMSL opt_sysvipc.h 165SEMOPM opt_sysvipc.h 166SEMUME opt_sysvipc.h 167SHMALL opt_sysvipc.h 168SHMMAX opt_sysvipc.h 169SHMMAXPGS opt_sysvipc.h 170SHMMIN opt_sysvipc.h 171SHMMNI opt_sysvipc.h 172SHMSEG opt_sysvipc.h 173SYSVMSG opt_sysvipc.h 174SYSVSEM opt_sysvipc.h 175SYSVSHM opt_sysvipc.h 176SW_WATCHDOG opt_watchdog.h 177TURNSTILE_PROFILING 178VFS_AIO 179VERBOSE_SYSINIT opt_global.h 180WLCACHE opt_wavelan.h 181WLDEBUG opt_wavelan.h 182 183# POSIX kernel options 184P1003_1B_MQUEUE opt_posix.h 185P1003_1B_SEMAPHORES opt_posix.h 186_KPOSIX_PRIORITY_SCHEDULING opt_posix.h 187 188# Do we want the config file compiled into the kernel? 189INCLUDE_CONFIG_FILE opt_config.h 190 191# Options for static filesystems.
