frequency generation and what frequency the generated was anyones guess. In general the 32.768kHz RTC clock x-tal was the best, because that was a regular wrist-watch Xtal, whereas the X-tal generating the ISA bus frequency was much lower quality, often costing as much as several cents a piece, so it made good sense to check the ISA bus frequency against the RTC clock. The other relevant property of those machines, is that they typically had no more than 16MB RAM. These days, CPU chips croak if their clocks are not tightly within specs and all necessary frequencies are derived from the master crystal by means if PLL's. Considering that it takes on average 1.5 second to calibrate the frequency of the i8254 counter, that more likely than not, we will not actually use the result of the calibration, and as the final clincher, we seldom use the i8254 for anything besides BEL in syscons anyway, it has become time to drop the calibration code. If you need to tell the system what frequency your i8254 runs, you can do so from the loader using hw.i8254.freq or using the sysctl kern.timecounter.tc.i8254.frequency.

|
||
|
||
#
|
||
# Options for CPU features.
|
||
#
|
||
# 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_FASTER_5X86_FPU enables faster FPU exception handler.
|
||
#
|
||
# 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_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.
|

# These options may crash your system.
