   23 # SMP OPTIONS:
   24 #
   25 # The apic device enables the use of the I/O APIC for interrupt delivery.
   26 # The apic device can be used in both UP and SMP kernels, but is required
   27 # for SMP kernels.  Thus, the apic device is not strictly an SMP option,
   28 # but it is a prerequisite for SMP.
   29 #
   30 # Notes:
   31 #
   32 # HTT CPUs should only be used if they are enabled in the BIOS.  For
   33 # the ACPI case, ACPI only correctly tells us about any HTT CPUs if
   34 # they are enabled.  However, most HTT systems do not list HTT CPUs
   35 # in the MP Table if they are enabled, thus we guess at the HTT CPUs
   36 # for the MP Table case.  However, we shouldn't try to guess and use
   37 # these CPUs if HTT is disabled.  Thus, HTT guessing is only enabled
   38 # for the MP Table if the user explicitly asks for it via the
   39 # MPTABLE_FORCE_HTT option.  Do NOT use this option if you have HTT
   40 # disabled in your BIOS.
   41 #
   42 # IPI_PREEMPTION instructs the kernel to preempt threads running on other
   43 # CPUS if needed.  Relies on the PREEMPTION option
   44 
   45 # Mandatory:

   48 # Optional:

   64 # CPU OPTIONS
   65 
   66 #
   67 # You must specify at least one CPU (the one you intend to run on);
   68 # deleting the specification for CPUs you don't need to use may make
   69 # parts of the system run faster.
   70 #
   71 cpu             I486_CPU
   72 cpu             I586_CPU                # aka Pentium(tm)
   73 cpu             I686_CPU                # aka Pentium Pro(tm)
   74 
   75 #
   76 # Options for CPU features.
   77 #
   78 # CPU_ATHLON_SSE_HACK tries to enable SSE instructions when the BIOS has
   79 # forgotten to enable them.
   80 #
   81 # CPU_BLUELIGHTNING_3X enables triple-clock mode on IBM Blue Lightning
   82 # CPU if CPU supports it.  The default is double-clock mode on
   83 # BlueLightning CPU box.
   84 #
   85 # CPU_BLUELIGHTNING_FPU_OP_CACHE enables FPU operand cache on IBM
   86 # BlueLightning CPU.  It works only with Cyrix FPU, and this option
   87 # should not be used with Intel FPU.
   88 #
   89 # CPU_BTB_EN enables branch target buffer on Cyrix 5x86 (NOTE 1).
   90 #
   91 # CPU_CYRIX_NO_LOCK enables weak locking for the entire address space
   92 # of Cyrix 6x86 and 6x86MX CPUs by setting the NO_LOCK bit of CCR1.
   93 # Otherwise, the NO_LOCK bit of CCR1 is cleared.  (NOTE 3)
   94 #
   95 # CPU_DIRECT_MAPPED_CACHE sets L1 cache of Cyrix 486DLC CPU in direct
   96 # mapped mode.  Default is 2-way set associative mode.
   97 #
   98 # CPU_DISABLE_5X86_LSSER disables load store serialize (i.e., enables
   99 # reorder).  This option should not be used if you use memory mapped
  100 # I/O device(s).
  101 #
  102 # CPU_DISABLE_CMPXCHG disables the CMPXCHG instruction on > i386 IA32
  103 # machines.  VmWare 3.x seems to emulate this instruction poorly, causing
  104 # the guest OS to run very slowly.  This problem appears to be fixed in
  105 # VmWare 4.x, at least in version 4.5.2, so that enabling this option with
  106 # VmWare 4.x will result in locking operations to be 20-30 times slower.
  107 # Enabling this with an SMP kernel will cause the kernel to be unusable.
  108 #
  109 # CPU_DISABLE_SSE explicitly prevents I686_CPU from turning on SSE.
  110 #
  111 # CPU_ELAN enables support for AMDs ElanSC520 CPU.
  112 #    CPU_ELAN_PPS enables precision timestamp code.
  113 #    CPU_ELAN_XTAL sets the clock crystal frequency in Hz.
  114 #
  115 # CPU_ENABLE_LONGRUN enables support for Transmeta Crusoe LongRun
  116 # technology which allows to restrict power consumption of the CPU by
  117 # using group of hw.crusoe.* sysctls.
  118 #
  119 # CPU_FASTER_5X86_FPU enables faster FPU exception handler.
  120 #
  121 # CPU_GEODE is for the SC1100 Geode embedded processor.  This option
  122 # is necessary because the i8254 timecounter is toast.
  123 #
  124 # CPU_I486_ON_386 enables CPU cache on i486 based CPU upgrade products
  125 # for i386 machines.
  126 #
  127 # CPU_IORT defines I/O clock delay time (NOTE 1).  Default values of
  128 # I/O clock delay time on Cyrix 5x86 and 6x86 are 0 and 7,respectively
  129 # (no clock delay).
  130 #
  131 # CPU_L2_LATENCY specifies the L2 cache latency value.  This option is used
  132 # only when CPU_PPRO2CELERON is defined and Mendocino Celeron is detected.
  133 # The default value is 5.
  134 #
  135 # CPU_LOOP_EN prevents flushing the prefetch buffer if the destination
  136 # of a jump is already present in the prefetch buffer on Cyrix 5x86(NOTE
  137 # 1).
  138 #
  139 # CPU_PPRO2CELERON enables L2 cache of Mendocino Celeron CPUs.  This option
  140 # is useful when you use Socket 8 to Socket 370 converter, because most Pentium
  141 # Pro BIOSs do not enable L2 cache of Mendocino Celeron CPUs.
  142 #
  143 # CPU_RSTK_EN enables return stack on Cyrix 5x86 (NOTE 1).
  144 #
  145 # CPU_SOEKRIS enables support www.soekris.com hardware.
  146 #
  147 # CPU_SUSP_HLT enables suspend on HALT.  If this option is set, CPU
  148 # enters suspend mode following execution of HALT instruction.
  149 #
  150 # CPU_UPGRADE_HW_CACHE eliminates unneeded cache flush instruction(s).
  151 #
  152 # CPU_WT_ALLOC enables write allocation on Cyrix 6x86/6x86MX and AMD
  153 # K5/K6/K6-2 CPUs.
  154 #
  155 # CYRIX_CACHE_WORKS enables CPU cache on Cyrix 486 CPUs with cache
  156 # flush at hold state.
  157 #
  158 # CYRIX_CACHE_REALLY_WORKS enables (1) CPU cache on Cyrix 486 CPUs
  159 # without cache flush at hold state, and (2) write-back CPU cache on
  160 # Cyrix 6x86 whose revision < 2.7 (NOTE 2).
  161 #
  162 # NO_F00F_HACK disables the hack that prevents Pentiums (and ONLY
  163 # Pentiums) from locking up when a LOCK CMPXCHG8B instruction is
  164 # executed.  This option is only needed if I586_CPU is also defined,
  165 # and should be included for any non-Pentium CPU that defines it.
  166 #
  167 # NO_MEMORY_HOLE is an optimisation for systems with AMD K6 processors
  168 # which indicates that the 15-16MB range is *definitely* not being
  169 # occupied by an ISA memory hole.
  170 #
  171 # NOTE 1: The options, CPU_BTB_EN, CPU_LOOP_EN, CPU_IORT,
  172 # CPU_LOOP_EN and CPU_RSTK_EN should not be used because of CPU bugs.
  173 # These options may crash your system.
  174 #
  175 # NOTE 2: If CYRIX_CACHE_REALLY_WORKS is not set, CPU cache is enabled
  176 # in write-through mode when revision < 2.7.  If revision of Cyrix
  177 # 6x86 >= 2.7, CPU cache is always enabled in write-back mode.
  178 #

  180 # locked cycles in order to operate correctly.

  235 # NETWORKING OPTIONS
  236 
  237 #
  238 # DEVICE_POLLING adds support for mixed interrupt-polling handling
  239 # of network device drivers, which has significant benefits in terms
  240 # of robustness to overloads and responsivity, as well as permitting
  241 # accurate scheduling of the CPU time between kernel network processing
  242 # and other activities.  The drawback is a moderate (up to 1/HZ seconds)
  243 # potential increase in response times.
  244 # It is strongly recommended to use HZ=1000 or 2000 with DEVICE_POLLING
  245 # to achieve smoother behaviour.
  246 # Additionally, you can enable/disable polling at runtime with help of
  247 # the ifconfig(8) utility, and select the CPU fraction reserved to
  248 # userland with the sysctl variable kern.polling.user_frac
  249 # (default 50, range 0..100).

  700 #  that hooks into the ACPI layer.  The device is hooked to the PIIX4's
  701 #  General Device 10 decoder, which means you have to fiddle with PCI
  702 #  registers to map it in, even though it is otherwise treated here as
  703 #  an ISA device.  At the moment, the driver polls, although the device
  704 #  is capable of generating interrupts.  It largely undocumented.
  705 #  The port location in the hint is where you WANT the device to be
  706 #  mapped.  0x10a0 seems to be traditional.  At the moment the jogdial
  707 #  is the only thing truly supported, but apparently a fair percentage
