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 affect 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 33 AAC_DEBUG opt_aac.h 34 AHC_ALLOW_MEMIO opt_aic7xxx.h 35 AHC_TMODE_ENABLE opt_aic7xxx.h 36 AHC_DUMP_EEPROM opt_aic7xxx.h 37 AHC_DEBUG opt_aic7xxx.h 38 AHC_DEBUG_OPTS opt_aic7xxx.h 39 AHC_REG_PRETTY_PRINT opt_aic7xxx.h 40 AHD_DEBUG opt_aic79xx.h 41 AHD_DEBUG_OPTS opt_aic79xx.h 42 AHD_TMODE_ENABLE opt_aic79xx.h 43 AHD_REG_PRETTY_PRINT opt_aic79xx.h 44 ADW_ALLOW_MEMIO opt_adw.h 45 46 TWA_DEBUG opt_twa.h 47 TWA_FLASH_FIRMWARE opt_twa.h 48 49 # Debugging options. 50 DDB 51 DDB_NUMSYM opt_ddb.h 52 GDB 53 GDBSPEED opt_gdb.h 54 KDB opt_global.h 55 KDB_TRACE opt_kdb.h 56 KDB_UNATTENDED opt_kdb.h 57 SYSCTL_DEBUG opt_sysctl.h 58 59 NO_SYSCTL_DESCR opt_global.h 60 61 # Miscellaneous options. 62 ADAPTIVE_GIANT opt_adaptive_mutexes.h 63 ADAPTIVE_SX 64 NO_ADAPTIVE_MUTEXES opt_adaptive_mutexes.h 65 NO_ADAPTIVE_RWLOCKS 66 ALQ 67 AUDIT opt_global.h 68 CODA_COMPAT_5 opt_coda.h 69 COMPAT_43 opt_compat.h 70 COMPAT_FREEBSD4 opt_compat.h 71 COMPAT_FREEBSD5 opt_compat.h 72 COMPILING_LINT opt_global.h 73 CONSPEED opt_comconsole.h 74 CY_PCI_FASTINTR 75 DIRECTIO opt_directio.h 76 FULL_PREEMPTION opt_sched.h 77 PREEMPTION opt_sched.h 78 IPI_PREEMPTION opt_sched.h 79 GEOM_AES opt_geom.h 80 GEOM_APPLE opt_geom.h 81 GEOM_BDE opt_geom.h 82 GEOM_BSD opt_geom.h 83 GEOM_CONCAT opt_geom.h 84 GEOM_ELI opt_geom.h 85 GEOM_FOX opt_geom.h 86 GEOM_GATE opt_geom.h 87 GEOM_GPT opt_geom.h 88 GEOM_LABEL opt_geom.h 89 GEOM_MBR opt_geom.h 90 GEOM_MIRROR opt_geom.h 91 GEOM_NOP opt_geom.h 92 GEOM_PC98 opt_geom.h 93 GEOM_RAID3 opt_geom.h 94 GEOM_SHSEC opt_geom.h 95 GEOM_STRIPE opt_geom.h 96 GEOM_SUNLABEL opt_geom.h 97 GEOM_UZIP opt_geom.h 98 GEOM_VOL opt_geom.h 99 GEOM_ZERO opt_geom.h 100 KSTACK_MAX_PAGES 101 KSTACK_PAGES 102 KTRACE 103 KTRACE_REQUEST_POOL opt_ktrace.h 104 LIBICONV 105 MAC 106 MAC_ALWAYS_LABEL_MBUF opt_mac.h 107 MAC_BIBA opt_dontuse.h 108 MAC_BSDEXTENDED opt_dontuse.h 109 MAC_DEBUG opt_mac.h 110 MAC_IFOFF opt_dontuse.h 111 MAC_LOMAC opt_dontuse.h 112 MAC_MLS opt_dontuse.h 113 MAC_NONE opt_dontuse.h 114 MAC_PARTITION opt_dontuse.h 115 MAC_PORTACL opt_dontuse.h 116 MAC_SEEOTHERUIDS opt_dontuse.h 117 MAC_STATIC opt_mac.h 118 MAC_STUB opt_dontuse.h 119 MAC_TEST opt_dontuse.h 120 MD_ROOT opt_md.h 121 MD_ROOT_SIZE opt_md.h 122 MFI_DEBUG opt_mfi.h 123 MPROF_BUFFERS opt_mprof.h 124 MPROF_HASH_SIZE opt_mprof.h 125 MUTEX_WAKE_ALL 126 NSWBUF_MIN opt_swap.h 127 PANIC_REBOOT_WAIT_TIME opt_panic.h 128 PPS_SYNC opt_ntp.h 129 PUC_FASTINTR opt_puc.h 130 QUOTA 131 SCHED_4BSD opt_sched.h 132 SCHED_ULE opt_sched.h 133 SHOW_BUSYBUFS 134 SLEEPQUEUE_PROFILING 135 SPX_HACK 136 SUIDDIR opt_suiddir.h 137 MSGMNB opt_sysvipc.h 138 MSGMNI opt_sysvipc.h 139 MSGSEG opt_sysvipc.h 140 MSGSSZ opt_sysvipc.h 141 MSGTQL opt_sysvipc.h 142 SEMMAP opt_sysvipc.h 143 SEMMNI opt_sysvipc.h 144 SEMMNS opt_sysvipc.h 145 SEMMNU opt_sysvipc.h 146 SEMMSL opt_sysvipc.h 147 SEMOPM opt_sysvipc.h 148 SEMUME opt_sysvipc.h 149 SHMALL opt_sysvipc.h 150 SHMMAX opt_sysvipc.h 151 SHMMAXPGS opt_sysvipc.h 152 SHMMIN opt_sysvipc.h 153 SHMMNI opt_sysvipc.h 154 SHMSEG opt_sysvipc.h 155 SYSVMSG opt_sysvipc.h 156 SYSVSEM opt_sysvipc.h 157 SYSVSHM opt_sysvipc.h 158 SW_WATCHDOG opt_watchdog.h 159 TURNSTILE_PROFILING 160 TTYHOG opt_tty.h 161 VFS_AIO 162 VERBOSE_SYSINIT opt_global.h 163 WLCACHE opt_wavelan.h 164 WLDEBUG opt_wavelan.h 165 166 # POSIX kernel options 167 P1003_1B_SEMAPHORES opt_posix.h 168 _KPOSIX_PRIORITY_SCHEDULING opt_posix.h 169 170 # Do we want the config file compiled into the kernel? 171 INCLUDE_CONFIG_FILE opt_config.h 172 173 # Options for static filesystems.
