Hello all, I am testing Cyclictest.

CONFIG_HIGH_RES_TIMERS=y are defined in .config then why I am getting "WARNING: High resolution timers not available". Why my results are not so impressive in realtime even though I defined: CONFIG_PREEMPT_RT=y CONFIG_PREEMPT=y CONFIG_PREEMPT_SOFTIRQS=y CONFIG_PREEMPT_HARDIRQS=y CONFIG_PREEMPT_BKL=y Min, Avg and Max are showing cyclic latencies. Ideally It should be ZERO. Am I right ?
