Next should come device, options, and hints lines in that 26# order. All device and option lines must be described by a comment that 27# doesn't just expand the device or option name. Use only a concise 28# comment on the same line if possible. Very detailed descriptions of 29# devices and subsystems belong in man pages. 30# 31# A space followed by a tab separates 'options' from an option name. Two 32# spaces followed by a tab separate 'device' from a device name. Comments 33# after an option or device should use one space after the comment character. 34# To comment out a negative option that disables code and thus should not be 35# enabled for LINT builds, precede 'options' with "#!". 36# 37 38# 39# This is the ``identification'' of the kernel. Usually this should 40# be the same as the name of your kernel. 41# 42ident LINT 43 44# 45# The `maxusers' parameter controls the static sizing of a number of 46# internal system tables by a formula defined in subr_param.c. 47# Omitting this parameter or setting it to 0 will cause the system to 48# auto-size based on physical memory. 49# 50maxusers 10 51 52# To statically compile in device wiring instead of /boot/device.hints 53#hints "LINT.hints" # Default places to look for devices. 54 55# Use the following to compile in values accessible to the kernel 56# through getenv() (or kenv(1) in userland).

The host adapters are listed in the ISA and PCI 1307# device configuration sections below. 1308# 1309# It is possible to wire down your SCSI devices so that a given bus, 1310# target, and LUN always come on line as the same device unit. In 1311# earlier versions the unit numbers were assigned in the order that 1312# the devices were probed on the SCSI bus. This means that if you 1313# removed a disk drive, you may have had to rewrite your /etc/fstab 1314# file, and also that you had to be careful when adding a new disk 1315# as it may have been probed earlier and moved your device configuration 1316# around. 1317 1318# This old behavior is maintained as the default behavior. The unit 1319# assignment begins with the first non-wired down unit for a device 1320# type. For example, if you wire a disk as "da3" then the first 1321# non-wired disk will be assigned da4. 1322 1323# The syntax for wiring down devices is: 1324 1325envvar hint.scbus.0.at="ahc0" 1326envvar hint.scbus.1.at="ahc1" 1327envvar hint.scbus.1.bus="0" 1328envvar hint.scbus.3.at="ahc2" 1329envvar hint.scbus.3.bus="0" 1330envvar hint.scbus.2.at="ahc2" 1331envvar hint.scbus.2.bus="1" 1332envvar hint.da.0.at="scbus0" 1333envvar hint.da.0.target="0" 1334envvar hint.da.0.unit="0" 1335envvar hint.da.1.at="scbus3" 1336envvar hint.da.1.target="1" 1337envvar hint.da.2.at="scbus2" 1338envvar hint.da.2.target="3" 1339envvar hint.sa.1.at="scbus1" 1340envvar hint.sa.1.target="6" 1341 1342# "units" (SCSI logical unit number) that are not specified are 1343# treated as if specified as LUN 0. 1344 1345# All SCSI devices allocate as many units as are required. 1346 1347# The ch driver drives SCSI Media Changer ("jukebox") devices. 1348# 1349# The da driver drives SCSI Direct Access ("disk") and Optical Media 1350# ("WORM") devices. 1351# 1352# The sa driver drives SCSI Sequential Access ("tape") devices. 1353# 1354# The cd driver drives SCSI Read Only Direct Access ("cd") devices. 1355# 1356# The ses driver drives SCSI Environment Services ("ses") and 1357# SAF-TE ("SCSI Accessible Fault-Tolerant Enclosure") devices. 1358# 1359# The pt driver drives SCSI Processor devices. 1360# 1361# The sg driver provides a passthrough API that is compatible with the 1362# Linux SG driver.

Note that 2764# the m_next pointer is NULL except when receiving > 4K 2765# jumbo frames or sustained bursts by way of LRO. Thus in 2766# the common case it is stirring zero in to the entropy 2767# pool. In cases where it is not NULL it is pointing to one 2768# of a small (in the thousands to 10s of thousands) number 2769# of 256 byte aligned mbufs. Hence it is, even in the best 2770# case, a poor source of entropy. And in the absence of actual 2771# runtime analysis of entropy collection may mislead the user in 2772# to believe that substantially more entropy is being collected 2773# than in fact is - leading to a different class of security 2774# risk. In high packet rate situations ethernet entropy 2775# collection is also very expensive, possibly leading to as 2776# much as a 50% drop in packets received. 2777# This option is present to maintain backwards compatibility 2778# if desired, however it cannot be recommended for use in any 2779# environment. 2780options RANDOM_ENABLE_ETHER # ether_input 2781 2782# Module to enable execution of application via emulators like QEMU 2783options IMGACT_BINMISC 2784 2785# zlib I/O stream support 2786# This enables support for compressed core dumps. 2787options GZIO 2788 2789# zstd support 2790# This enables support for Zstd compressed core dumps, GEOM_UZIP images, 2791# and is required by zfs if statically linked. 2792options ZSTDIO 2793 2794# BHND(4) drivers 2795options BHND_LOGLEVEL # Logging threshold level 2796 2797# evdev interface 2798device evdev # input event device support 2799options EVDEV_SUPPORT # evdev support in legacy drivers 2800options EVDEV_DEBUG # enable event debug msgs 2801device uinput # install /dev/uinput cdev 2802options UINPUT_DEBUG # enable uinput debug msgs 2803 2804# Encrypted kernel crash dumps. 2805options EKCD 2806 2807# Serial Peripheral Interface (SPI) support. 2808device spibus # Bus support. 2809device at45d # DataFlash driver 2810device cqspi # 2811device mx25l # SPIFlash driver 2812device n25q # 2813device spigen # Generic access to SPI devices from userland. 2814# Enable legacy /dev/spigenN name aliases for /dev/spigenX.Y devices. 2815options SPIGEN_LEGACY_CDEVNAME # legacy device names for spigen 2816 2817# Compression supports. 2818device zlib # gzip/zlib compression/decompression library 2819device xz # xz_embedded LZMA de-compression library 2820 2821# Kernel support for stats(3). 2822options STATS 2823
