They need to start and end counting at the same time, therefore related events are best used in the same event group to get the expected value. There are two ways to know if they are related events: + a) By event name, such as the latency events "xxx_latency, xxx_cnt" or bandwidth events "xxx_flux, xxx_time". b) By event type, such as "event=0xXXXX, event=0x1XXXX". |
