kernel: 2.6.14 with and without the realtime-preempt patch hi list, after measuring the duration of the function udelay (with oscilloscope at parallel port), I figured out that udelay (5usec) with activated realtime- preempt patch lasts a little bit longer. Without the patch the time is exact. All kernel debug switches are turned off at compile time. Can anyone suggest why this happens? christoph - 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/ | |||||||||
