# 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:
|
||
#
|
||
# Be sure to disable 'cpu I386_CPU' for SMP kernels.
|
||
#
|
||
# 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.

# NETWORKING OPTIONS

# DEVICE_POLLING adds support for mixed interrupt-polling handling

# of network device drivers, which has significant benefits in terms

# of robustness to overloads and responsivity, as well as permitting

# accurate scheduling of the CPU time between kernel network processing

|

# potential increase in response times.
|
||
# It is strongly recommended to use HZ=1000 or 2000 with DEVICE_POLLING
|
||
# to achieve smoother behaviour.
|
||
# Additionally, you can enable/disable polling at runtime with the
|
||
# sysctl variable kern.polling.enable (defaults off), and select
|
||
# the CPU fraction reserved to userland with the sysctl variable
|
||
# kern.polling.user_frac (default 50, range 0..100).
