Subject: I need some help with struct clock_event_device (please cc me)

Hi list,

I need some help with with struct clock_event_device.

Can someone please spare the time to explain to me what exactly is delta in

.set_next_event()

It is probably me being stupid, but I do not get it. If delta is ticks 
(and hence HZ dependent), how is it possible to pass sub-tick values for 
high res timers? If delta is not ticks, exactly what it is and how does 
it depend on shift, mul and other fields in that structure.

Please cc me, I am not subscribed to the list.
