If you mean it for the real time clock: Doesn't make sense then because Linux time isn't measured in cycles If you mean it for the scheduler: it only uses estimates for relative fairness. As long as everybody is sloeed down in the same way the relative fairness doesn't change. For time accounting: the regular timer interrupt is fairly imprecise anyawys because it samples at a low frequency. While it would be possible to improve this it would be quite costly by slowing down interrupts and syscalls. I'm not sure it makes that much difference here either. I don't see the point, frankly. -Andi - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
