1# 2# LINT -- config file for checking all the sources, tries to pull in 3# as much of the source tree as it can. 4# 5# $FreeBSD: head/sys/conf/NOTES 52909 1999-11-05 20:37:23Z obrien $ 6# 7# NB: You probably don't want to try running a kernel built from this 8# file. Instead, you should start from GENERIC, and add options from 9# this file as required. 10# 11 12# 13# This directive is mandatory; it defines the architecture to be 14# configured for; in this case, the 386 family based IBM-PC and 15# compatibles. 16# 17machine i386 18 19# 20# This is the ``identification'' of the kernel. Usually this should 21# be the same as the name of your kernel. 22# 23ident LINT 24 25# 26# The `maxusers' parameter controls the static sizing of a number of 27# internal system tables by a complicated formula defined in param.c. 28# 29maxusers 10 30 31# 32# The `makeoptions' parameter allows variables to be passed to the 33# generated Makefile in the build area. 34# 35# CONF_CFLAGS gives some extra compiler flags that are added to ${CFLAGS} 36# after most other flags. Here we use it to inhibit use of non-optimal 37# gcc builtin functions (e.g., memcmp). 38# 39# DEBUG happens to be magic. 40# The following is equivalent to 'config -g KERNELNAME' and creates 41# 'kernel.debug' compiled with -g debugging as well as a normal 42# 'kernel'. Use 'make install.debug' to install the debug kernel 43# but that isn't normally necessary as the debug symbols are not loaded 44# by the kernel and are not useful there anyway. 45# 46# KERNEL can be overridden so that you can change the default name of your 47# kernel. 48# 49makeoptions CONF_CFLAGS=-fno-builtin #Don't allow use of memcmp, etc. 50#makeoptions DEBUG=-g #Build kernel with gdb(1) debug symbols 51#makeoptions KERNEL=foo #Build kernel "foo" and install "/foo" 52 53# 54# Certain applications can grow to be larger than the 128M limit 55# that FreeBSD initially imposes. Below are some options to 56# allow that limit to grow to 256MB, and can be increased further 57# with changing the parameters. MAXDSIZ is the maximum that the 58# limit can be set to, and the DFLDSIZ is the default value for 59# the limit. You might want to set the default lower than the 60# max, and explicitly set the maximum with a shell command for processes 61# that regularly exceed the limit like INND. 62# 63options MAXDSIZ="(256*1024*1024)" 64options DFLDSIZ="(256*1024*1024)" 65 66# 67# BLKDEV_IOSIZE sets the default block size used in user block 68# device I/O.

It works only with Cyrix FPU, and this option 146# should not be used with Intel FPU. 147# 148# CPU_BLUELIGHTNING_3X enables triple-clock mode on IBM Blue Lightning 149# CPU if CPU supports it. The default is double-clock mode on 150# BlueLightning CPU box. 151# 152# CPU_BTB_EN enables branch target buffer on Cyrix 5x86 (NOTE 1). 153# 154# CPU_DIRECT_MAPPED_CACHE sets L1 cache of Cyrix 486DLC CPU in direct 155# mapped mode. Default is 2-way set associative mode. 156# 157# CPU_CYRIX_NO_LOCK enables weak locking for the entire address space 158# of Cyrix 6x86 and 6x86MX CPUs by setting the NO_LOCK bit of CCR1. 159# Otherwise, the NO_LOCK bit of CCR1 is cleared. (NOTE 3) 160# 161# CPU_DISABLE_5X86_LSSER disables load store serialize (i.e. enables 162# reorder). This option should not be used if you use memory mapped 163# I/O device(s). 164# 165# CPU_FASTER_5X86_FPU enables faster FPU exception handler. 166# 167# CPU_I486_ON_386 enables CPU cache on i486 based CPU upgrade products 168# for i386 machines. 169# 170# CPU_IORT defines I/O clock delay time (NOTE 1). Default values of 171# I/O clock delay time on Cyrix 5x86 and 6x86 are 0 and 7,respectively 172# (no clock delay). 173# 174# CPU_LOOP_EN prevents flushing the prefetch buffer if the destination 175# of a jump is already present in the prefetch buffer on Cyrix 5x86(NOTE 176# 1). 177# 178# CPU_RSTK_EN enables return stack on Cyrix 5x86 (NOTE 1). 179# 180# CPU_SUSP_HLT enables suspend on HALT. If this option is set, CPU 181# enters suspend mode following execution of HALT instruction. 182# 183# CPU_WT_ALLOC enables write allocation on Cyrix 6x86/6x86MX and AMD 184# K5/K6/K6-2 cpus. 185# 186# CYRIX_CACHE_WORKS enables CPU cache on Cyrix 486 CPUs with cache 187# flush at hold state. 188# 189# CYRIX_CACHE_REALLY_WORKS enables (1) CPU cache on Cyrix 486 CPUs 190# without cache flush at hold state, and (2) write-back CPU cache on 191# Cyrix 6x86 whose revision < 2.7 (NOTE 2). 192# 193# NO_F00F_HACK disables the hack that prevents Pentiums (and ONLY 194# Pentiums) from locking up when a LOCK CMPXCHG8B instruction is 195# executed. This should be included for ALL kernels that won't run 196# on a Pentium. 197# 198# NO_MEMORY_HOLE is an optimisation for systems with AMD K6 processors 199# which indicates that the 15-16MB range is *definitely* not being 200# occupied by an ISA memory hole. 201# 202# NOTE 1: The options, CPU_BTB_EN, CPU_LOOP_EN, CPU_IORT, 203# CPU_LOOP_EN and CPU_RSTK_EN should not be used because of CPU bugs. 204# These options may crash your system. 205# 206# NOTE 2: If CYRIX_CACHE_REALLY_WORKS is not set, CPU cache is enabled 207# in write-through mode when revision < 2.7.

It is a prerequisite for 315# 'INVARIANTS', as enabling 'INVARIANTS' will make these functions be 316# called. The intent is that you can set 'INVARIANTS' for single 317# source files (by changing the source file or specifying it on the 318# command line) if you have 'INVARIANT_SUPPORT' enabled. 319# 320options INVARIANT_SUPPORT 321 322# 323# The DIAGNOSTIC option is used to enable extra debugging information 324# from some parts of the kernel.

The host adapters are listed in the ISA and PCI 698# device configuration sections below. 699# 700# Beginning with FreeBSD 2.0.5 you can wire down your SCSI devices so 701# that a given bus, target, and LUN always come on line as the same 702# device unit. In earlier versions the unit numbers were assigned 703# in the order that the devices were probed on the SCSI bus. This 704# means that if you removed a disk drive, you may have had to rewrite 705# your /etc/fstab file, and also that you had to be careful when adding 706# a new disk as it may have been probed earlier and moved your device 707# configuration around. 708 709# This old behavior is maintained as the default behavior. The unit 710# assignment begins with the first non-wired down unit for a device 711# type. For example, if you wire a disk as "da3" then the first 712# non-wired disk will be assigned da4. 713 714# The syntax for wiring down devices is: 715 716# controller scbus0 at ahc0 # Single bus device 717# controller scbus1 at ahc1 bus 0 # Single bus device 718# controller scbus3 at ahc2 bus 0 # Twin bus device 719# controller scbus2 at ahc2 bus 1 # Twin bus device 720# device da0 at scbus0 target 0 unit 0 721# device da1 at scbus3 target 1 722# device da2 at scbus2 target 3 723# device sa1 at scbus1 target 6 724# device cd0 at scbus? 725 726# "units" (SCSI logical unit number) that are not specified are 727# treated as if specified as LUN 0. 728 729# All SCSI devices allocate as many units as are required. 730 731# The "unknown" device (uk? in pre-2.0.5) is now part of the base SCSI 732# configuration and doesn't have to be explicitly configured. 733 734controller scbus0 #base SCSI code 735device ch0 #SCSI media changers 736device da0 #SCSI direct access devices (aka disks) 737device sa0 #SCSI tapes 738device cd0 #SCSI CD-ROMs 739device pass0 #CAM passthrough driver 740 741# The previous devices (ch, da, st, cd) are recognized by config. 742# config doesn't (and shouldn't) know about these newer ones, 743# so we have to specify that they are on a SCSI bus with the "at scbus?" 744# clause. 745 746device pt0 at scbus? # SCSI processor type 747 748# CAM OPTIONS: 749# debugging options: 750# -- NOTE -- If you specify one of the bus/target/lun options, you must 751# specify them all! 752# CAMDEBUG: When defined enables debugging macros 753# CAM_DEBUG_BUS: Debug the given bus.

This driver also 1629# supports the Accton EN1207D `Cheetah' adapter, which uses a chip called 1630# the MPX 5030/5038, which is either a RealTek in disguise or a RealTek 1631# workalike. 1632# 1633# The 'sf' device provides support for Adaptec Duralink PCI fast 1634# ethernet adapters based on the Adaptec AIC-6915 "starfire" controller. 1635# This includes dual and quad port cards, as well as one 100baseFX card. 1636# Most of these are 64-bit PCI devices, except for one single port 1637# card which is 32-bit. 1638# 1639# The 'ste' device provides support for adapters based on the Sundance 1640# Technologies ST201 PCI fast ethernet controller. This includes the 1641# D-Link DFE-550TX. 1642# 1643# The 'sis' device provides support for adapters based on the Silicon 1644# Integrated Systems SiS 900 and SiS 7016 PCI fast ethernet controller 1645# chips. 1646# 1647# The 'sk' device provides support for the SysKonnect SK-984x series 1648# PCI gigabit ethernet NICs. This includes the SK-9841 and SK-9842 1649# single port cards (single mode and multimode fiber) and the 1650# SK-9843 and SK-9844 dual port cards (also single mode and multimode). 1651# The driver will autodetect the number of ports on the card and 1652# attach each one as a separate network interface. 1653# 1654# The 'ti' device provides support for PCI gigabit ethernet NICs based 1655# on the Alteon Networks Tigon 1 and Tigon 2 chipsets. This includes the 1656# Alteon AceNIC, the 3Com 3c985, the Netgear GA620 and various others. 1657# Note that you will probably want to bump up NMBCLUSTERS a lot to use 1658# this driver. 1659# 1660# The 'tl' device provides support for the Texas Instruments TNETE100 1661# series 'ThunderLAN' cards and integrated ethernet controllers. This 1662# includes several Compaq Netelligent 10/100 cards and the built-in 1663# ethernet controllers in several Compaq Prosignia, Proliant and 1664# Deskpro systems. It also supports several Olicom 10Mbps and 10/100 1665# boards. 1666# 1667# The `tx' device provides support for the SMC 9432TX cards. 1668# 1669# The `vr' device provides support for various fast ethernet adapters 1670# based on the VIA Technologies VT3043 `Rhine I' and VT86C100A `Rhine II' 1671# chips, including the D-Link DFE530TX, the Hawking Technologies PN102TX, 1672# and the AOpen/Acer ALN-320. 1673# 1674# The `vx' device provides support for the 3Com 3C590 and 3C595 1675# early support 1676# 1677# The `wb' device provides support for various fast ethernet adapters 1678# based on the Winbond W89C840F chip. Note: this is not the same as 1679# the Winbond W89C940F, which is an NE2000 clone. 1680# 1681# The `xl' device provides support for the 3Com 3c900, 3c905 and 1682# 3c905B (Fast) Etherlink XL cards and integrated controllers. This 1683# includes the integrated 3c905B-TX chips in certain Dell Optiplex and 1684# Dell Precision desktop machines and the integrated 3c905-TX chips 1685# in Dell Latitude laptop docking stations. 1686# 1687# The `fpa' device provides support for the Digital DEFPA PCI FDDI 1688# adapter. pseudo-device fddi is also needed. 1689# 1690# The `meteor' device is a PCI video capture board. It can also have the 1691# following options: 1692# options METEOR_ALLOC_PAGES=xxx preallocate kernel pages for data entry 1693# figure (ROWS*COLUMN*BYTES_PER_PIXEL*FRAME+PAGE_SIZE-1)/PAGE_SIZE 1694# options METEOR_DEALLOC_PAGES remove all allocated pages on close(2) 1695# options METEOR_DEALLOC_ABOVE=xxx remove all allocated pages above the 1696# specified amount.

This growth 2201# will NOT shrink. To restrict the number of queue 2202# slots to exactly what the DPT can hold at one time, 2203# enable this option. 2204# DPT_MEASURE_PERFORMANCE Enables a set of (semi)invasive metrics. Various 2205# instruments are enabled. The tools in 2206# /usr/sbin/dpt_* assume these to be enabled. 2207# DPT_FREELIST_IS_STACK For optimal L{1,2} CPU cache utilization, enable 2208# this option. Otherwise, the transaction queue is 2209# a LIFO. I cannot measure the performance gain. 2210# DPT_HANDLE_TIMEOUTS Normally device timeouts are handled by the DPT. 2211# If you ant the driver to handle timeouts, enable 2212# this option. If your system is very busy, this 2213# option will create more trouble than solve. 2214# DPT_TIMEOUT_FACTOR Used to compute the excessive amount of time to 2215# wait when timing out with the above option. 2216# DPT_DEBUG_xxxx These are controllable from sys/dev/dpt/dpt.h 2217# DPT_LOST_IRQ When enabled, will try, once per second, to catch 2218# any interrupt that got lost. Seems to help in some 2219# DPT-firmware/Motherboard combinations. Minimal 2220# cost, great benefit. 2221# DPT_RESET_HBA Make "reset" actually reset the controller 2222# instead of fudging it.
