25 # The apic device enables the use of the I/O APIC for interrupt delivery.
26 # The apic device can be used in both UP and SMP kernels, but is required
27 # for SMP kernels. Thus, the apic device is not strictly an SMP option,
28 # but it is a prerequisite for SMP.
32 # By default, mixed mode is used to route IRQ0 from the AT timer via
33 # the 8259A master PIC through the ExtINT pin on the first I/O APIC.
34 # This can be disabled via the NO_MIXED_MODE option. In that case,
35 # IRQ0 will be routed via an intpin on the first I/O APIC. Not all
36 # motherboards hook IRQ0 up to the first I/O APIC even though their
37 # MP table or MADT may claim to do so. That is why mixed mode is
40 # HTT CPUs should only be used if they are enabled in the BIOS. For
41 # the ACPI case, ACPI only correctly tells us about any HTT CPUs if
42 # they are enabled. However, most HTT systems do not list HTT CPUs
43 # in the MP Table if they are enabled, thus we guess at the HTT CPUs
44 # for the MP Table case. However, we shouldn't try to guess and use
45 # these CPUs if HTT is disabled. Thus, HTT guessing is only enabled
46 # for the MP Table if the user explicitly asks for it via the
