Then added several general CMN700 metrics and yitian710 soc DDR metrics. Since the eventid of cmn700 events is different from other events, it can't be specified by "EventCode" or "ConfigCode", so in the cmn.json file of cmn700, no "EventCode" and "ConfigCode" are added for these events. For example, the eventid of "arm_cmn_0/hnf_sf_hit is/": cat /sys/bus/event_source/devices/arm_cmn_0/events/hnf_sf_hit type=0x5,eventid=0x6 In addition, both cmn700 and ddr PMU can count the information in a die, but the same SoC can also be configured with different numbers of dies, so it is dificult to design a general expression to obtain metrics in different dies. The current yitian710 ddr bandwidth metric describes the sum of all dies bandwidth. I would like to ask you, is there any general expression can obtain metrics for die? Add an option to specify die?
