See /boot/device.hints and/or the 'hints' config(8) directive. # # Please use ``make LINT'' to create an old-style LINT file if you want to # do kernel test-builds. # # This file contains machine independent kernel configuration notes. For # machine dependent notes, look in /sys//conf/NOTES. # # # NOTES conventions and style guide: # # Large block comments should begin and end with a line containing only a # comment character. # # To describe a particular object, a block comment (if it exists) should # come first. Next should come device, options, and hints lines in that # order. All device and option lines must be described by a comment that # doesn't just expand the device or option name. Use only a concise # comment on the same line if possible. Very detailed descriptions of # devices and subsystems belong in man pages. # # A space followed by a tab separates 'options' from an option name. Two # spaces followed by a tab separate 'device' from a device name. Comments # after an option or device should use one space after the comment character. # To comment out a negative option that disables code and thus should not be # enabled for LINT builds, precede 'options' with "#!". # # # This is the ``identification'' of the kernel. Usually this should # be the same as the name of your kernel. # ident LINT # # The `maxusers' parameter controls the static sizing of a number of # internal system tables by a formula defined in subr_param.c. # Omitting this parameter or setting it to 0 will cause the system to # auto-size based on physical memory. # maxusers 10 # To statically compile in device wiring instead of /boot/device.hints #hints "LINT.hints" # Default places to look for devices. # Use the following to compile in values accessible to the kernel # through getenv() (or kenv(1) in userland). The format of the file # is 'variable=value', see kenv(1) # #env "LINT.env" # # The `makeoptions' parameter allows variables to be passed to the # generated Makefile in the build area. # # CONF_CFLAGS gives some extra compiler flags that are added to ${CFLAGS} # after most other flags. Here we use it to inhibit use of non-optimal # gcc built-in functions (e.g., memcmp). # # DEBUG happens to be magic. # The following is equivalent to 'config -g KERNELNAME' and creates # 'kernel.debug' compiled with -g debugging as well as a normal # 'kernel'. Use 'make install.debug' to install the debug kernel # but that isn't normally necessary as the debug symbols are not loaded # by the kernel and are not useful there anyway. # # KERNEL can be overridden so that you can change the default name of your # kernel. # # MODULES_OVERRIDE can be used to limit modules built to a specific list. # makeoptions CONF_CFLAGS=-fno-builtin #Don't allow use of memcmp, etc. #makeoptions DEBUG=-g #Build kernel with gdb(1) debug symbols #makeoptions KERNEL=foo #Build kernel "foo" and install "/foo" # Only build ext2fs module plus those parts of the sound system I need. #makeoptions MODULES_OVERRIDE="ext2fs sound/sound sound/driver/maestro3" makeoptions DESTDIR=/tmp # # FreeBSD processes are subject to certain limits to their consumption # of system resources.

The purpose is to isolate # different malloc types into hash classes, so that any buffer # overruns or use-after-free will usually only affect memory from # malloc types in that hash class. This is purely a debugging tool; # by varying the hash function and tracking which hash class was # corrupted, the intersection of the hash classes from each instance # will point to a single malloc type that is being misused. At this # point inspection or memguard(9) can be used to catch the offending # code. # options MALLOC_DEBUG_MAXZONES=8 # # DEBUG_MEMGUARD builds and enables memguard(9), a replacement allocator # for the kernel used to detect modify-after-free scenarios. See the # memguard(9) man page for more information on usage. # options DEBUG_MEMGUARD # # DEBUG_REDZONE enables buffer underflows and buffer overflows detection for # malloc(9). # options DEBUG_REDZONE # # EARLY_PRINTF enables support for calling a special printf (eprintf) # very early in the kernel (before cn_init() has been called). This # should only be used for debugging purposes early in boot. Normally, # it is not defined. It is commented out here because this feature # isn't generally available. And the required eputc() isn't defined. # #options EARLY_PRINTF # # KTRACE enables the system-call tracing facility ktrace(2). To be more # SMP-friendly, KTRACE uses a worker thread to process most trace events # asynchronously to the thread generating the event. This requires a # pre-allocated store of objects representing trace events. The # KTRACE_REQUEST_POOL option specifies the initial size of this store. # The size of the pool can be adjusted both at boottime and runtime via # the kern.ktrace_request_pool tunable and sysctl. # options KTRACE #kernel tracing options KTRACE_REQUEST_POOL=101 # # KTR is a kernel tracing facility imported from BSD/OS. It is # enabled with the KTR option. KTR_ENTRIES defines the number of # entries in the circular trace buffer; it may be an arbitrary number. # KTR_BOOT_ENTRIES defines the number of entries during the early boot, # before malloc(9) is functional. # KTR_COMPILE defines the mask of events to compile into the kernel as # defined by the KTR_* constants in . KTR_MASK defines the # initial value of the ktr_mask variable which determines at runtime # what events to trace. KTR_CPUMASK determines which CPU's log # events, with bit X corresponding to CPU X. The layout of the string # passed as KTR_CPUMASK must match a series of bitmasks each of them # separated by the "," character (ie: # KTR_CPUMASK=0xAF,0xFFFFFFFFFFFFFFFF). KTR_VERBOSE enables # dumping of KTR events to the console by default. This functionality # can be toggled via the debug.ktr_verbose sysctl and defaults to off # if KTR_VERBOSE is not defined.

This support is not # enabled by default because of the extra time it would take to check # for these conditions, which can only occur as a result of # programming errors. # options INVARIANTS # # The INVARIANT_SUPPORT option makes us compile in support for # verifying some of the internal structures. It is a prerequisite for # 'INVARIANTS', as enabling 'INVARIANTS' will make these functions be # called. The intent is that you can set 'INVARIANTS' for single # source files (by changing the source file or specifying it on the # command line) if you have 'INVARIANT_SUPPORT' enabled. Also, if you # wish to build a kernel module with 'INVARIANTS', then adding # 'INVARIANT_SUPPORT' to your kernel will provide all the necessary # infrastructure without the added overhead. # options INVARIANT_SUPPORT # # The DIAGNOSTIC option is used to enable extra debugging information # from some parts of the kernel. As this makes everything more noisy, # it is disabled by default. # options DIAGNOSTIC # # REGRESSION causes optional kernel interfaces necessary only for regression # testing to be enabled. These interfaces may constitute security risks # when enabled, as they permit processes to easily modify aspects of the # run-time environment to reproduce unlikely or unusual (possibly normally # impossible) scenarios. # options REGRESSION # # This option lets some drivers co-exist that can't co-exist in a running # system. This is used to be able to compile all kernel code in one go for # quality assurance purposes (like this file, which the option takes it name # from.) # options COMPILING_LINT # # STACK enables the stack(9) facility, allowing the capture of kernel stack # for the purpose of procinfo(1), etc. stack(9) will also be compiled in # automatically if DDB(4) is compiled into the kernel. # options STACK ##################################################################### # PERFORMANCE MONITORING OPTIONS # # The hwpmc driver that allows the use of in-CPU performance monitoring # counters for performance monitoring.

The host adapters are listed in the ISA and PCI # device configuration sections below. # # It is possible to wire down your SCSI devices so that a given bus, # target, and LUN always come on line as the same device unit. In # earlier versions the unit numbers were assigned in the order that # the devices were probed on the SCSI bus. This means that if you # removed a disk drive, you may have had to rewrite your /etc/fstab # file, and also that you had to be careful when adding a new disk # as it may have been probed earlier and moved your device configuration # around. (See also option GEOM_VOL for a different solution to this # problem.) # This old behavior is maintained as the default behavior. The unit # assignment begins with the first non-wired down unit for a device # type. For example, if you wire a disk as "da3" then the first # non-wired disk will be assigned da4. # The syntax for wiring down devices is: hint.scbus.0.at="ahc0" hint.scbus.1.at="ahc1" hint.scbus.1.bus="0" hint.scbus.3.at="ahc2" hint.scbus.3.bus="0" hint.scbus.2.at="ahc2" hint.scbus.2.bus="1" hint.da.0.at="scbus0" hint.da.0.target="0" hint.da.0.unit="0" hint.da.1.at="scbus3" hint.da.1.target="1" hint.da.2.at="scbus2" hint.da.2.target="3" hint.sa.1.at="scbus1" hint.sa.1.target="6" # "units" (SCSI logical unit number) that are not specified are # treated as if specified as LUN 0. # All SCSI devices allocate as many units as are required. # The ch driver drives SCSI Media Changer ("jukebox") devices. # # The da driver drives SCSI Direct Access ("disk") and Optical Media # ("WORM") devices. # # The sa driver drives SCSI Sequential Access ("tape") devices. # # The cd driver drives SCSI Read Only Direct Access ("cd") devices. # # The ses driver drives SCSI Environment Services ("ses") and # SAF-TE ("SCSI Accessible Fault-Tolerant Enclosure") devices. # # The pt driver drives SCSI Processor devices. # # The sg driver provides a passthrough API that is compatible with the # Linux SG driver.

It can also stand on its own and provide # source level API compatibility for porting apps to FreeBSD. # # Target Mode support is provided here but also requires that a SIM # (SCSI Host Adapter Driver) provide support as well. # # The targ driver provides target mode support as a Processor type device. # It exists to give the minimal context necessary to respond to Inquiry # commands.

$FreeBSD$ # # On the handling of kernel options # # All kernel options should be listed in NOTES, with suitable # descriptions. Negative options (options that make some code not # compile) should be commented out; LINT (generated from NOTES) should # compile as much code as possible. Try to structure option-using # code so that a single option only switch code on, or only switch # code off, to make it possible to have a full compile-test. If # necessary, you can check for COMPILING_LINT to get maximum code # coverage. # # All new options shall also be listed in either "conf/options" or # "conf/options.". Options that affect a single source-file # .[c|s] should be directed into "opt_.h", while options # that affect multiple files should either go in "opt_global.h" if # this is a kernel-wide option (used just about everywhere), or in # "opt_.h" if it affects only some files. # Note that the effect of listing only an option without a # header-file-name in conf/options (and cousins) is that the last # convention is followed. # # This handling scheme is not yet fully implemented. # # # Format of this file: # Option name filename # # If filename is missing, the default is # opt_.h AAC_DEBUG opt_aac.h AACRAID_DEBUG opt_aacraid.h AHC_ALLOW_MEMIO opt_aic7xxx.h AHC_TMODE_ENABLE opt_aic7xxx.h AHC_DUMP_EEPROM opt_aic7xxx.h AHC_DEBUG opt_aic7xxx.h AHC_DEBUG_OPTS opt_aic7xxx.h AHC_REG_PRETTY_PRINT opt_aic7xxx.h AHD_DEBUG opt_aic79xx.h AHD_DEBUG_OPTS opt_aic79xx.h AHD_TMODE_ENABLE opt_aic79xx.h AHD_REG_PRETTY_PRINT opt_aic79xx.h ADW_ALLOW_MEMIO opt_adw.h TWA_DEBUG opt_twa.h TWA_FLASH_FIRMWARE opt_twa.h # Debugging options.

M_HASHTYPE_OPAQUE can be set by non-RSS cards or configurations * that provide an opaque flow identifier, allowing for ordering and * distribution without explicit affinity. */ /* Microsoft RSS standard hash types */ #define M_HASHTYPE_NONE 0 #define M_HASHTYPE_RSS_IPV4 1 /* IPv4 2-tuple */ #define M_HASHTYPE_RSS_TCP_IPV4 2 /* TCPv4 4-tuple */ #define M_HASHTYPE_RSS_IPV6 3 /* IPv6 2-tuple */ #define M_HASHTYPE_RSS_TCP_IPV6 4 /* TCPv6 4-tuple */ #define M_HASHTYPE_RSS_IPV6_EX 5 /* IPv6 2-tuple + ext hdrs */ #define M_HASHTYPE_RSS_TCP_IPV6_EX 6 /* TCPv6 4-tiple + ext hdrs */ /* Non-standard RSS hash types */ #define M_HASHTYPE_RSS_UDP_IPV4 7 /* IPv4 UDP 4-tuple */ #define M_HASHTYPE_RSS_UDP_IPV4_EX 8 /* IPv4 UDP 4-tuple + ext hdrs */ #define M_HASHTYPE_RSS_UDP_IPV6 9 /* IPv6 UDP 4-tuple */ #define M_HASHTYPE_RSS_UDP_IPV6_EX 10 /* IPv6 UDP 4-tuple + ext hdrs */ #define M_HASHTYPE_OPAQUE 255 /* ordering, not affinity */ #define M_HASHTYPE_CLEAR(m) ((m)->m_pkthdr.rsstype = 0) #define M_HASHTYPE_GET(m) ((m)->m_pkthdr.rsstype) #define M_HASHTYPE_SET(m, v) ((m)->m_pkthdr.rsstype = (v)) #define M_HASHTYPE_TEST(m, v) (M_HASHTYPE_GET(m) == (v)) /* * COS/QOS class and quality of service tags. * It uses DSCP code points as base. */ #define QOS_DSCP_CS0 0x00 #define QOS_DSCP_DEF QOS_DSCP_CS0 #define QOS_DSCP_CS1 0x20 #define QOS_DSCP_AF11 0x28 #define QOS_DSCP_AF12 0x30 #define QOS_DSCP_AF13 0x38 #define QOS_DSCP_CS2 0x40 #define QOS_DSCP_AF21 0x48 #define QOS_DSCP_AF22 0x50 #define QOS_DSCP_AF23 0x58 #define QOS_DSCP_CS3 0x60 #define QOS_DSCP_AF31 0x68 #define QOS_DSCP_AF32 0x70 #define QOS_DSCP_AF33 0x78 #define QOS_DSCP_CS4 0x80 #define QOS_DSCP_AF41 0x88 #define QOS_DSCP_AF42 0x90 #define QOS_DSCP_AF43 0x98 #define QOS_DSCP_CS5 0xa0 #define QOS_DSCP_EF 0xb8 #define QOS_DSCP_CS6 0xc0 #define QOS_DSCP_CS7 0xe0 /* * External mbuf storage buffer types. */ #define EXT_CLUSTER 1 /* mbuf cluster */ #define EXT_SFBUF 2 /* sendfile(2)'s sf_bufs */ #define EXT_JUMBOP 3 /* jumbo cluster 4096 bytes */ #define EXT_JUMBO9 4 /* jumbo cluster 9216 bytes */ #define EXT_JUMBO16 5 /* jumbo cluster 16184 bytes */ #define EXT_PACKET 6 /* mbuf+cluster from packet zone */ #define EXT_MBUF 7 /* external mbuf reference (M_IOVEC) */ #define EXT_VENDOR1 224 /* for vendor-internal use */ #define EXT_VENDOR2 225 /* for vendor-internal use */ #define EXT_VENDOR3 226 /* for vendor-internal use */ #define EXT_VENDOR4 227 /* for vendor-internal use */ #define EXT_EXP1 244 /* for experimental use */ #define EXT_EXP2 245 /* for experimental use */ #define EXT_EXP3 246 /* for experimental use */ #define EXT_EXP4 247 /* for experimental use */ #define EXT_NET_DRV 252 /* custom ext_buf provided by net driver(s) */ #define EXT_MOD_TYPE 253 /* custom module's ext_buf type */ #define EXT_DISPOSABLE 254 /* can throw this buffer away w/page flipping */ #define EXT_EXTREF 255 /* has externally maintained ext_cnt ptr */ /* * Flags for external mbuf buffer types. * NB: limited to the lower 24 bits. */ #define EXT_FLAG_EMBREF 0x000001 /* embedded ext_cnt, notyet */ #define EXT_FLAG_EXTREF 0x000002 /* external ext_cnt, notyet */ #define EXT_FLAG_NOFREE 0x000010 /* don't free mbuf to pool, notyet */ #define EXT_FLAG_VENDOR1 0x010000 /* for vendor-internal use */ #define EXT_FLAG_VENDOR2 0x020000 /* for vendor-internal use */ #define EXT_FLAG_VENDOR3 0x040000 /* for vendor-internal use */ #define EXT_FLAG_VENDOR4 0x080000 /* for vendor-internal use */ #define EXT_FLAG_EXP1 0x100000 /* for experimental use */ #define EXT_FLAG_EXP2 0x200000 /* for experimental use */ #define EXT_FLAG_EXP3 0x400000 /* for experimental use */ #define EXT_FLAG_EXP4 0x800000 /* for experimental use */ /* * EXT flag description for use with printf(9) %b identifier. */ #define EXT_FLAG_BITS \ "\20\1EXT_FLAG_EMBREF\2EXT_FLAG_EXTREF\5EXT_FLAG_NOFREE" \ "\21EXT_FLAG_VENDOR1\22EXT_FLAG_VENDOR2\23EXT_FLAG_VENDOR3" \ "\24EXT_FLAG_VENDOR4\25EXT_FLAG_EXP1\26EXT_FLAG_EXP2\27EXT_FLAG_EXP3" \ "\30EXT_FLAG_EXP4" /* * External reference/free functions. */ void sf_ext_ref(void *, void *); void sf_ext_free(void *, void *); /* * Flags indicating checksum, segmentation and other offload work to be * done, or already done, by hardware or lower layers.
