Yeah, it was just to prove things right on the console without getting into traces. > Or better yet: have trace_hrtimer_interrupt() which we can compare against > trace_hrtimer_expire_entry/exit() to check if any hrtimer callback have run > in the interrupt. This way we avoid workarounds like the above count. Yeah, I also believe we better add this debug information to mainline kernel. I will try to get a patch for that soon. Would it be recommended to add both trace points? i.e. trace_hrtimer_interrupt() and trace_hrtimer_spurious() ? -- viresh -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
