   55 # You must specify at least one CPU (the one you intend to run on);
   56 # deleting the specification for CPUs you don't need to use may make
   57 # parts of the system run faster.
   58 # I386_CPU is mutually exclusive with the other CPU types.

   64 
   65 #
   66 # Options for CPU features.
   67 #
   68 # CPU_ATHLON_SSE_HACK tries to enable SSE instructions when the BIOS has
   69 # forgotten to enable them.
   70 #
   71 # CPU_BLUELIGHTNING_FPU_OP_CACHE enables FPU operand cache on IBM
   72 # BlueLightning CPU.  It works only with Cyrix FPU, and this option
   73 # should not be used with Intel FPU.
   74 #
   75 # CPU_BLUELIGHTNING_3X enables triple-clock mode on IBM Blue Lightning
   76 # CPU if CPU supports it. The default is double-clock mode on
   77 # BlueLightning CPU box.
   78 #
   79 # CPU_BTB_EN enables branch target buffer on Cyrix 5x86 (NOTE 1).
   80 #
   81 # CPU_DIRECT_MAPPED_CACHE sets L1 cache of Cyrix 486DLC CPU in direct
   82 # mapped mode.  Default is 2-way set associative mode.
   83 #
   84 # CPU_CYRIX_NO_LOCK enables weak locking for the entire address space
   85 # of Cyrix 6x86 and 6x86MX CPUs by setting the NO_LOCK bit of CCR1.
   86 # Otherwise, the NO_LOCK bit of CCR1 is cleared.  (NOTE 3)
   87 #
   88 # CPU_DISABLE_5X86_LSSER disables load store serialize (i.e. enables
   89 # reorder).  This option should not be used if you use memory mapped
   90 # I/O device(s).
   91 #
   92 # CPU_ELAN enables support for AMDs ElanSC520 CPU.
   93 #    ELAN_XTAL sets the clock crystal frequency in Hz
   94 #    ELAN_PPS enables precision timestamp code.
   95 #
   96 # CPU_ENABLE_SSE enables SSE/MMX2 instructions support.  This is default
   97 # on I686_CPU and above.
   98 # CPU_DISABLE_SSE explicitly prevent I686_CPU from turning on SSE.
   99 #
  100 # CPU_FASTER_5X86_FPU enables faster FPU exception handler.
  101 #
  102 # CPU_I486_ON_386 enables CPU cache on i486 based CPU upgrade products
  103 # for i386 machines.
  104 #
  105 # CPU_IORT defines I/O clock delay time (NOTE 1).  Default values of
  106 # I/O clock delay time on Cyrix 5x86 and 6x86 are 0 and 7,respectively
  107 # (no clock delay).
  108 #
  109 # CPU_L2_LATENCY specifed the L2 cache latency value.  This option is used
  110 # only when CPU_PPRO2CELERON is defined and Mendocino Celeron is detected.
  111 # The default value is 5.
  112 #
  113 # CPU_LOOP_EN prevents flushing the prefetch buffer if the destination
  114 # of a jump is already present in the prefetch buffer on Cyrix 5x86(NOTE
  115 # 1).
  116 #
  117 # CPU_PPRO2CELERON enables L2 cache of Mendocino Celeron CPUs.  This option
  118 # is useful when you use Socket 8 to Socket 370 converter, because most Pentium
  119 # Pro BIOSs do not enable L2 cache of Mendocino Celeron CPUs.
  120 #
  121 # CPU_RSTK_EN enables return stack on Cyrix 5x86 (NOTE 1).
  122 #
  123 # CPU_SUSP_HLT enables suspend on HALT.  If this option is set, CPU
  124 # enters suspend mode following execution of HALT instruction.
  125 #
  126 # CPU_UPGRADE_HW_CACHE eliminates unneeded cache flush instruction(s).
  127 #
  128 # CPU_WT_ALLOC enables write allocation on Cyrix 6x86/6x86MX and AMD
  129 # K5/K6/K6-2 cpus.
  130 #
  131 # CYRIX_CACHE_WORKS enables CPU cache on Cyrix 486 CPUs with cache
  132 # flush at hold state.
  133 #
  134 # CYRIX_CACHE_REALLY_WORKS enables (1) CPU cache on Cyrix 486 CPUs
  135 # without cache flush at hold state, and (2) write-back CPU cache on
  136 # Cyrix 6x86 whose revision < 2.7 (NOTE 2).
  137 #
  138 # NO_F00F_HACK disables the hack that prevents Pentiums (and ONLY
  139 # Pentiums) from locking up when a LOCK CMPXCHG8B instruction is
  140 # executed.  This option is only needed if I586_CPU is also defined,
  141 # and should be included for any non-Pentium CPU that defines it.
  142 #
  143 # NO_MEMORY_HOLE is an optimisation for systems with AMD K6 processors
  144 # which indicates that the 15-16MB range is *definitely* not being
  145 # occupied by an ISA memory hole.
  146 #
  147 # CPU_DISABLE_CMPXCHG disables the CMPXCHG instruction on > i386 IA32 
  148 # machines.  VmWare seems to emulate this instruction poorly, causing 
  149 # the guest OS to run very slowly.  Enabling this with a SMP kernel
  150 # will cause the kernel to be unusable.
  151 #
  152 # NOTE 1: The options, CPU_BTB_EN, CPU_LOOP_EN, CPU_IORT,
  153 # CPU_LOOP_EN and CPU_RSTK_EN should not be used because of CPU bugs.
  154 # These options may crash your system.
  155 #
  156 # NOTE 2: If CYRIX_CACHE_REALLY_WORKS is not set, CPU cache is enabled
  157 # in write-through mode when revision < 2.7.  If revision of Cyrix
  158 # 6x86 >= 2.7, CPU cache is always enabled in write-back mode.

  161 # locked cycles in order to operate correctly.

  214 # DEVICE_POLLING adds support for mixed interrupt-polling handling
  215 # of network device drivers, which has significant benefits in terms
  216 # of robustness to overloads and responsivity, as well as permitting
  217 # accurate scheduling of the CPU time between kernel network processing
  218 # and other activities. The drawback is a moderate (up to 1/HZ seconds)
  219 # potential increase in response times.
  220 # It is strongly recommended to use HZ=1000 or 2000 with DEVICE_POLLING
  221 # to achieve smoother behaviour.
  222 # Additionally, you can enable/disable polling at runtime with the
  223 # sysctl variable kern.polling.enable (defaults off), and select

  282 # MAXMEM specifies the amount of RAM on the machine; if this is not

  608 #  I/O memory is an 8kb region.  Possible values are:

  616 # Notes on the Specialix SI/XIO driver:

  622 # Notes on the Sony Programmable I/O controller
  623 #  This is a temporary driver that should someday be replaced by something
  624 #  that hooks into the ACPI layer. The device is hooked to the PIIX4's
  625 #  General Device 10 decoder, which means you have to fiddle with PCI
  626 #  registers to map it in, even though it is otherwise treated here as
  627 #  an ISA device. At the moment, the driver polls, although the device
  628 #  is capable of generating interrupts. It largely undocumented.
  629 #  The port location in the hint is where you WANT the device to be
  630 #  mapped. 0x10a0 seems to be traditional. At the moment the jogdial
  631 #  is the only thing truly supported, but aparently a fair percentage
  632 #  of the Vaio extra features are controlled by this device.
  633 
  634 # Notes on the Stallion stl and stli drivers:
  635 #  See src/i386/isa/README.stl for complete instructions.
  636 #  This is version 0.0.5alpha, unsupported by Stallion.
  637 #  The stl driver has a secondary IO port hard coded at 0x280.  You need
  638 #     to change src/i386/isa/stallion.c if you reconfigure this on the boards.
  639 #  The "flags" and "msize" settings on the stli driver depend on the board:
  640 #       EasyConnection 8/64 ISA:     flags 23         msize 0x1000
  641 #       EasyConnection 8/64 EISA:    flags 24         msize 0x10000
