26# SMP OPTIONS:
27#
28# The apic device enables the use of the I/O APIC for interrupt delivery.
29# The apic device can be used in both UP and SMP kernels, but is required
30# for SMP kernels. Thus, the apic device is not strictly an SMP option,
31# but it is a prerequisite for SMP.
32#
33# Notes:
34#
35# Be sure to disable 'cpu I386_CPU' for SMP kernels.
36#
37# By default, mixed mode is used to route IRQ0 from the AT timer via
38# the 8259A master PIC through the ExtINT pin on the first I/O APIC.
39# This can be disabled via the NO_MIXED_MODE option. In that case,
40# IRQ0 will be routed via an intpin on the first I/O APIC. Not all
41# motherboards hook IRQ0 up to the first I/O APIC even though their
42# MP table or MADT may claim to do so. That is why mixed mode is
43# enabled by default.

350#
351# The svr4 ABI emulator can be statically compiled into the kernel or loaded as
352# a KLD module.
353# The STREAMS network emulation code can also be compiled statically or as a
354# module. If loaded as a module, it must be loaded before the svr4 module
355# (the /usr/sbin/svr4 script does this for you). If compiling statically,
356# the `streams' device must be configured into any kernel which also
357# specifies COMPAT_SVR4. It is possible to have a statically-configured
358# STREAMS device and a dynamically loadable svr4 emulator; the /usr/sbin/svr4
359# script understands that it doesn't need to load the `streams' module under
360# those circumstances.
361# Caveat: At this time, `options KTRACE' is required for the svr4 emulator
362# (whether static or dynamic).
