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_NUMSYM opt_ddb.h 52GDB 53KDB opt_global.h 54KDB_TRACE opt_kdb.h 55KDB_UNATTENDED opt_kdb.h 56SYSCTL_DEBUG opt_sysctl.h 57 58NO_SYSCTL_DESCR opt_global.h 59 60# Miscellaneous options. 61ADAPTIVE_SX 62ALQ 63AUDIT opt_global.h 64CODA_COMPAT_5 opt_coda.h 65COMPAT_43 opt_compat.h 66COMPAT_43TTY opt_compat.h 67COMPAT_FREEBSD4 opt_compat.h 68COMPAT_FREEBSD5 opt_compat.h 69COMPAT_FREEBSD6 opt_compat.h 70COMPILING_LINT opt_global.h 71CY_PCI_FASTINTR 72DIRECTIO 73FULL_PREEMPTION opt_sched.h 74IPI_PREEMPTION opt_sched.h 75GEOM_AES opt_geom.h 76GEOM_BDE opt_geom.h 77GEOM_BSD opt_geom.h 78GEOM_CACHE opt_geom.h 79GEOM_CONCAT opt_geom.h 80GEOM_ELI opt_geom.h 81GEOM_FOX opt_geom.h 82GEOM_GATE opt_geom.h 83GEOM_JOURNAL opt_geom.h 84GEOM_LABEL opt_geom.h 85GEOM_MBR opt_geom.h 86GEOM_MIRROR opt_geom.h 87GEOM_MULTIPATH opt_geom.h 88GEOM_NOP opt_geom.h 89GEOM_PART_APM opt_geom.h 90GEOM_PART_BSD opt_geom.h 91GEOM_PART_GPT opt_geom.h 92GEOM_PART_MBR opt_geom.h 93GEOM_PC98 opt_geom.h 94GEOM_RAID3 opt_geom.h 95GEOM_SHSEC opt_geom.h 96GEOM_STRIPE opt_geom.h 97GEOM_SUNLABEL opt_geom.h 98GEOM_UZIP opt_geom.h 99GEOM_VIRSTOR opt_geom.h 100GEOM_VOL opt_geom.h 101GEOM_ZERO opt_geom.h 102KSE opt_global.h 103KSTACK_MAX_PAGES 104KSTACK_PAGES 105KTRACE 106KTRACE_REQUEST_POOL opt_ktrace.h 107LIBICONV 108MAC 109MAC_ALWAYS_LABEL_MBUF opt_mac.h 110MAC_BIBA opt_dontuse.h 111MAC_BSDEXTENDED opt_dontuse.h 112MAC_IFOFF opt_dontuse.h 113MAC_LOMAC opt_dontuse.h 114MAC_MLS opt_dontuse.h 115MAC_NONE opt_dontuse.h 116MAC_PARTITION opt_dontuse.h 117MAC_PORTACL opt_dontuse.h 118MAC_SEEOTHERUIDS opt_dontuse.h 119MAC_STATIC opt_mac.h 120MAC_STUB opt_dontuse.h 121MAC_TEST opt_dontuse.h 122MD_ROOT opt_md.h 123MD_ROOT_SIZE opt_md.h 124MFI_DEBUG opt_mfi.h 125MFI_DECODE_LOG opt_mfi.h 126MPROF_BUFFERS opt_mprof.h 127MPROF_HASH_SIZE opt_mprof.h 128NO_ADAPTIVE_MUTEXES opt_adaptive_mutexes.h 129NO_ADAPTIVE_RWLOCKS 130NSWBUF_MIN opt_swap.h 131MBUF_PACKET_ZONE_DISABLE opt_global.h 132PANIC_REBOOT_WAIT_TIME opt_panic.h 133PPC_DEBUG opt_ppc.h 134PPC_PROBE_CHIPSET opt_ppc.h 135PPS_SYNC opt_ntp.h 136PREEMPTION opt_sched.h 137QUOTA 138SCHED_4BSD opt_sched.h 139SCHED_ULE opt_sched.h 140SHOW_BUSYBUFS 141SLEEPQUEUE_PROFILING 142SLHCI_DEBUG opt_slhci.h 143SPX_HACK 144STACK opt_stack.h 145SUIDDIR 146MSGMNB opt_sysvipc.h 147MSGMNI opt_sysvipc.h 148MSGSEG opt_sysvipc.h 149MSGSSZ opt_sysvipc.h 150MSGTQL opt_sysvipc.h 151SEMMAP opt_sysvipc.h 152SEMMNI opt_sysvipc.h 153SEMMNS opt_sysvipc.h 154SEMMNU opt_sysvipc.h 155SEMMSL opt_sysvipc.h 156SEMOPM opt_sysvipc.h 157SEMUME opt_sysvipc.h 158SHMALL opt_sysvipc.h 159SHMMAX opt_sysvipc.h 160SHMMAXPGS opt_sysvipc.h 161SHMMIN opt_sysvipc.h 162SHMMNI opt_sysvipc.h 163SHMSEG opt_sysvipc.h 164SYSVMSG opt_sysvipc.h 165SYSVSEM opt_sysvipc.h 166SYSVSHM opt_sysvipc.h 167SW_WATCHDOG opt_watchdog.h 168TURNSTILE_PROFILING 169TTYHOG opt_tty.h 170VFS_AIO 171VERBOSE_SYSINIT opt_global.h 172WLCACHE opt_wavelan.h 173WLDEBUG opt_wavelan.h 174 175# POSIX kernel options 176P1003_1B_MQUEUE opt_posix.h 177P1003_1B_SEMAPHORES opt_posix.h 178_KPOSIX_PRIORITY_SCHEDULING opt_posix.h 179 180# Do we want the config file compiled into the kernel? 181INCLUDE_CONFIG_FILE opt_config.h 182 183# Options for static filesystems.
