To avoid the external timer - * IRQ APIC event being in synchron with the APIC clock we - * introduce an interrupt skew to spread out timer events. - * - * The number of slices within a 'big' timeslice is NR_CPUS+1 - */ - I did some thinking, and I don't understand how this old code can be legal. Doesn't this make do_gettimeofday() inaccurate? I must be missing something. - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/ | ||||||||||||
