# # NOTES -- Lines that can be cut/pasted into kernel and hints configs. # # This file contains machine dependent kernel configuration notes. For # machine independent notes, look in /sys/conf/NOTES. # # $FreeBSD: release/9.1.0/sys/i386/conf/NOTES 235926 2012-05-24 19:24:31Z bz $ # # # We want LINT to cover profiling as well. profile 2 # # Enable the kernel DTrace hooks which are required to load the DTrace # kernel modules. # options KDTRACE_HOOKS ##################################################################### # SMP OPTIONS: # # The apic device enables the use of the I/O APIC for interrupt delivery. # The apic device can be used in both UP and SMP kernels, but is required # for SMP kernels. Thus, the apic device is not strictly an SMP option, # but it is a prerequisite for SMP. # # Notes: # # HTT CPUs should only be used if they are enabled in the BIOS. For # the ACPI case, ACPI only correctly tells us about any HTT CPUs if # they are enabled. However, most HTT systems do not list HTT CPUs # in the MP Table if they are enabled, thus we guess at the HTT CPUs # for the MP Table case. However, we shouldn't try to guess and use # these CPUs if HTT is disabled. Thus, HTT guessing is only enabled # for the MP Table if the user explicitly asks for it via the # MPTABLE_FORCE_HTT option. Do NOT use this option if you have HTT # disabled in your BIOS. # # IPI_PREEMPTION instructs the kernel to preempt threads running on other # CPUS if needed. Relies on the PREEMPTION option # Mandatory: device apic # I/O apic # Optional: options MPTABLE_FORCE_HTT # Enable HTT CPUs with the MP Table options IPI_PREEMPTION # # Watchdog routines. # options MP_WATCHDOG # Debugging options. # options COUNT_XINVLTLB_HITS # Counters for TLB events options COUNT_IPIS # Per-CPU IPI interrupt counters ##################################################################### # CPU OPTIONS # # You must specify at least one CPU (the one you intend to run on); # deleting the specification for CPUs you don't need to use may make # parts of the system run faster. # cpu I486_CPU cpu I586_CPU # aka Pentium(tm) cpu I686_CPU # aka Pentium Pro(tm) # # Options for CPU features. # # CPU_ATHLON_SSE_HACK tries to enable SSE instructions when the BIOS has # forgotten to enable them. # # CPU_BLUELIGHTNING_3X enables triple-clock mode on IBM Blue Lightning # CPU if CPU supports it. The default is double-clock mode on # BlueLightning CPU box. # # CPU_BLUELIGHTNING_FPU_OP_CACHE enables FPU operand cache on IBM # BlueLightning CPU. It works only with Cyrix FPU, and this option # should not be used with Intel FPU. # # CPU_BTB_EN enables branch target buffer on Cyrix 5x86 (NOTE 1). # # CPU_CYRIX_NO_LOCK enables weak locking for the entire address space # of Cyrix 6x86 and 6x86MX CPUs by setting the NO_LOCK bit of CCR1. # Otherwise, the NO_LOCK bit of CCR1 is cleared. (NOTE 3) # # CPU_DIRECT_MAPPED_CACHE sets L1 cache of Cyrix 486DLC CPU in direct # mapped mode. Default is 2-way set associative mode. # # CPU_DISABLE_5X86_LSSER disables load store serialize (i.e., enables # reorder). This option should not be used if you use memory mapped # I/O device(s). # # CPU_DISABLE_CMPXCHG disables the CMPXCHG instruction on > i386 IA32 # machines. VmWare 3.x seems to emulate this instruction poorly, causing # the guest OS to run very slowly. This problem appears to be fixed in # VmWare 4.x, at least in version 4.5.2, so that enabling this option with # VmWare 4.x will result in locking operations to be 20-30 times slower. # Enabling this with an SMP kernel will cause the kernel to be unusable. # # CPU_DISABLE_SSE explicitly prevents I686_CPU from turning on SSE. # # CPU_ELAN enables support for AMDs ElanSC520 CPU. # CPU_ELAN_PPS enables precision timestamp code. # CPU_ELAN_XTAL sets the clock crystal frequency in Hz. # # CPU_ENABLE_LONGRUN enables support for Transmeta Crusoe LongRun # technology which allows to restrict power consumption of the CPU by # using group of hw.crusoe.* sysctls. # # CPU_FASTER_5X86_FPU enables faster FPU exception handler. # # CPU_GEODE is for the SC1100 Geode embedded processor. This option # is necessary because the i8254 timecounter is toast. # # CPU_I486_ON_386 enables CPU cache on i486 based CPU upgrade products # for i386 machines. # # CPU_IORT defines I/O clock delay time (NOTE 1). Default values of # I/O clock delay time on Cyrix 5x86 and 6x86 are 0 and 7,respectively # (no clock delay). # # CPU_L2_LATENCY specifies the L2 cache latency value. This option is used # only when CPU_PPRO2CELERON is defined and Mendocino Celeron is detected. # The default value is 5. # # CPU_LOOP_EN prevents flushing the prefetch buffer if the destination # of a jump is already present in the prefetch buffer on Cyrix 5x86(NOTE # 1). # # CPU_PPRO2CELERON enables L2 cache of Mendocino Celeron CPUs. This option # is useful when you use Socket 8 to Socket 370 converter, because most Pentium # Pro BIOSs do not enable L2 cache of Mendocino Celeron CPUs. # # CPU_RSTK_EN enables return stack on Cyrix 5x86 (NOTE 1). # # CPU_SOEKRIS enables support www.soekris.com hardware. # # CPU_SUSP_HLT enables suspend on HALT. If this option is set, CPU # enters suspend mode following execution of HALT instruction. # # CPU_UPGRADE_HW_CACHE eliminates unneeded cache flush instruction(s). # # CPU_WT_ALLOC enables write allocation on Cyrix 6x86/6x86MX and AMD # K5/K6/K6-2 CPUs. # # CYRIX_CACHE_WORKS enables CPU cache on Cyrix 486 CPUs with cache # flush at hold state. # # CYRIX_CACHE_REALLY_WORKS enables (1) CPU cache on Cyrix 486 CPUs # without cache flush at hold state, and (2) write-back CPU cache on # Cyrix 6x86 whose revision < 2.7 (NOTE 2). # # NO_F00F_HACK disables the hack that prevents Pentiums (and ONLY # Pentiums) from locking up when a LOCK CMPXCHG8B instruction is # executed. This option is only needed if I586_CPU is also defined, # and should be included for any non-Pentium CPU that defines it. # # NO_MEMORY_HOLE is an optimisation for systems with AMD K6 processors # which indicates that the 15-16MB range is *definitely* not being # occupied by an ISA memory hole. # # NOTE 1: The options, CPU_BTB_EN, CPU_LOOP_EN, CPU_IORT, # CPU_LOOP_EN and CPU_RSTK_EN should not be used because of CPU bugs. # These options may crash your system. # # NOTE 2: If CYRIX_CACHE_REALLY_WORKS is not set, CPU cache is enabled # in write-through mode when revision < 2.7. If revision of Cyrix # 6x86 >= 2.7, CPU cache is always enabled in write-back mode. # # NOTE 3: This option may cause failures for software that requires # locked cycles in order to operate correctly. # options CPU_ATHLON_SSE_HACK options CPU_BLUELIGHTNING_3X options CPU_BLUELIGHTNING_FPU_OP_CACHE options CPU_BTB_EN options CPU_DIRECT_MAPPED_CACHE options CPU_DISABLE_5X86_LSSER options CPU_DISABLE_CMPXCHG #options CPU_DISABLE_SSE options CPU_ELAN options CPU_ELAN_PPS options CPU_ELAN_XTAL=32768000 options CPU_ENABLE_LONGRUN options CPU_FASTER_5X86_FPU options CPU_GEODE options CPU_I486_ON_386 options CPU_IORT options CPU_L2_LATENCY=5 options CPU_LOOP_EN options CPU_PPRO2CELERON options CPU_RSTK_EN options CPU_SOEKRIS options CPU_SUSP_HLT options CPU_UPGRADE_HW_CACHE options CPU_WT_ALLOC options CYRIX_CACHE_WORKS options CYRIX_CACHE_REALLY_WORKS #options NO_F00F_HACK # Debug options options NPX_DEBUG # enable npx debugging # # PERFMON causes the driver for Pentium/Pentium Pro performance counters # to be compiled.

It is fully USB- # keyboard aware, and will only be used if an xbox is detected. This option # (obviously) requires XBOX support in your kernel. # # NOTE: xboxfb currently conflicts with syscons(4); if you have an XBOX and # include both in your kernel; you will not get any video output. Ordinary # PC's do not suffer from this. # options XBOX device xboxfb ##################################################################### # NETWORKING OPTIONS # # DEVICE_POLLING adds support for mixed interrupt-polling handling # of network device drivers, which has significant benefits in terms # of robustness to overloads and responsivity, as well as permitting # accurate scheduling of the CPU time between kernel network processing # and other activities. The drawback is a moderate (up to 1/HZ seconds) # potential increase in response times. # It is strongly recommended to use HZ=1000 or 2000 with DEVICE_POLLING # to achieve smoother behaviour. # Additionally, you can enable/disable polling at runtime with help of # the ifconfig(8) utility, and select the CPU fraction reserved to # userland with the sysctl variable kern.polling.user_frac # (default 50, range 0..100). # # Not all device drivers support this mode of operation at the time of # this writing. See polling(4) for more details. options DEVICE_POLLING # BPF_JITTER adds support for BPF just-in-time compiler. options BPF_JITTER ##################################################################### # CLOCK OPTIONS # Provide read/write access to the memory in the clock chip. device nvram # Access to rtc cmos via /dev/nvram ##################################################################### # MISCELLANEOUS DEVICES AND OPTIONS device speaker #Play IBM BASIC-style noises out your speaker hint.speaker.0.at="isa" hint.speaker.0.port="0x61" device gzip #Exec gzipped a.out's.

This saves about 0.7-1.25 usec for each interrupt. # This option breaks suspend/resume on some portables. # # AUTO_EOI_2 enables the `automatic EOI' feature for the slave 8259A # interrupt controller. This saves about 0.7-1.25 usec for each interrupt. # Automatic EOI is documented not to work for for the slave with the # original i8259A, but it works for some clones and some integrated # versions. # # MAXMEM specifies the amount of RAM on the machine; if this is not # specified, FreeBSD will first read the amount of memory from the CMOS # RAM, so the amount of memory will initially be limited to 64MB or 16MB # depending on the BIOS. If the BIOS reports 64MB, a memory probe will # then attempt to detect the installed amount of RAM. If this probe # fails to detect >64MB RAM you will have to use the MAXMEM option. # The amount is in kilobytes, so for a machine with 128MB of RAM, it would # be 131072 (128 * 1024). # # BROKEN_KEYBOARD_RESET disables the use of the keyboard controller to # reset the CPU for reboot.

For PAE # kernels, the value will need to be double non-PAE.
