┌─── Local APIC support on uniprocessors ──────────────────┐ │ CONFIG_X86_UP_APIC: │ │ │ │ A local APIC (Advanced Programmable Interrupt Controller) is an │ │ integrated interrupt controller in the CPU. If you have a single-CPU │ │ system which has a processor with a local APIC, you can say Y here to │ │ enable and use it. If you say Y here even though your machine doesn't │ │ have a local APIC, then the kernel will still run with no slowdown at │ │ all. The local APIC supports CPU-generated self-interrupts (timer, │ │ performance counters), and the NMI watchdog which detects hard │ │ lockups. │ │ │ │ If you have a system with several CPUs, you do not need to say Y │ │ here: the local APIC will be used automatically. │ │ │ │ │ │ │ ├─────────────────────────────────────(100%)──┤ │ < Exit > │ └───────────────────────────────────────────┘
