# 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.
