18 # The apic device enables the use of the I/O APIC for interrupt delivery.
19 # The apic device can be used in both UP and SMP kernels, but is required
20 # for SMP kernels. Thus, the apic device is not strictly an SMP option,
21 # but it is a prerequisite for SMP.
25 # HTT CPUs should only be used if they are enabled in the BIOS. For
26 # the ACPI case, ACPI only correctly tells us about any HTT CPUs if
27 # they are enabled. However, most HTT systems do not list HTT CPUs
28 # in the MP Table if they are enabled, thus we guess at the HTT CPUs
29 # for the MP Table case. However, we shouldn't try to guess and use
30 # these CPUs if HTT is disabled. Thus, HTT guessing is only enabled
31 # for the MP Table if the user explicitly asks for it via the
32 # MPTABLE_FORCE_HTT option. Do NOT use this option if you have HTT
33 # disabled in your BIOS.

236 # DEVICE_POLLING adds support for mixed interrupt-polling handling
237 # of network device drivers, which has significant benefits in terms
238 # of robustness to overloads and responsivity, as well as permitting
239 # accurate scheduling of the CPU time between kernel network processing
240 # and other activities. The drawback is a moderate (up to 1/HZ seconds)
241 # potential increase in response times.
242 # It is strongly recommended to use HZ=1000 or 2000 with DEVICE_POLLING
243 # to achieve smoother behaviour.
