# 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:
|
||||
#
|
||||
# By default, mixed mode is used to route IRQ0 from the AT timer via
|
||||
# the 8259A master PIC through the ExtINT pin on the first I/O APIC.
|
||||
# This can be disabled via the NO_MIXED_MODE option. In that case,
|
||||
# IRQ0 will be routed via an intpin on the first I/O APIC. Not all
|
||||
# motherboards hook IRQ0 up to the first I/O APIC even though their
|
||||
# MP table or MADT may claim to do so. That is why mixed mode is
|
||||
# enabled by default.

# a KLD module.
|

# The STREAMS network emulation code can also be compiled statically or as a
|
||||
# module. If loaded as a module, it must be loaded before the svr4 module
|
||||
# (the /usr/sbin/svr4 script does this for you). If compiling statically,
|
||||
# the `streams' device must be configured into any kernel which also
|
||||
# specifies COMPAT_SVR4. It is possible to have a statically-configured
|
||||
# STREAMS device and a dynamically loadable svr4 emulator; the /usr/sbin/svr4
|
||||
# script understands that it doesn't need to load the `streams' module under
|
||||
# those circumstances.
|

# Caveat: At this time, `options KTRACE' is required for the svr4 emulator

# (whether static or dynamic).
