I agree that the time diff between taking the timestamp in the interrupt handler vs taking it in the threaded irq context is negligible. Having said that it is still important as we would like to have the same timestamp for events that finished together, rather than having different timestamps when we process the events in the threaded irq handler. > What actually 'more accurate' mean in this context ? > > Regards > Stanislaw By 'more accurate' we mean closest to the MSIX interrupt. Ofir.
