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.

130 # CPU_LOOP_EN prevents flushing the prefetch buffer if the destination
131 # of a jump is already present in the prefetch buffer on Cyrix 5x86(NOTE
134 # CPU_PPRO2CELERON enables L2 cache of Mendocino Celeron CPUs. This option
135 # is useful when you use Socket 8 to Socket 370 converter, because most Pentium
136 # Pro BIOSs do not enable L2 cache of Mendocino Celeron CPUs.

237 # of network device drivers, which has significant benefits in terms
238 # of robustness to overloads and responsivity, as well as permitting

240 # and other activities. The drawback is a moderate (up to 1/HZ seconds)
