Dynamic Ticks for Low Resolution Systems

Consider the situation in which the kernel does not use high-resolution timers and provides only low resolution. How are dynamic ticks implemented in this scenario? Recall from above that the timer softIRQ calls hrtimer_run_queues to process the high-resolution timer queue, even if only low resolution is available in the underlying clock event device. Again, I emphasize that this does not provide better resolution for timers, but makes it possible to use the existing framework independent of the clock resolution.
