Group #1 events had both upper and lower case characters in their names. Trying to count such events with perf tool results in an error: $ perf stat -e dwc_rootport_10008/Tx_PCIe_TLP_Data_Payload/ sleep 1 event syntax error: 'dwc_rootport_10008/Tx_PCIe_TLP_Data_Payload/' \___ Bad event or PMU Unable to find PMU or event on a PMU of 'dwc_rootport_10008' event syntax error: '..port_10008/Tx_PCIe_TLP_Data_Payload/' \___ unknown term 'Tx_PCIe_TLP_Data_Payload' for pmu 'dwc_rootport_10008' valid terms: eventid,type,lane,config,config1,config2,config3,name,period,percore,metric-id Run 'perf list' for a list of valid events Usage: perf stat [<options>] [<command>] -e, --event <event> event selector. use 'perf list' to list available events Perf tool assumes the event names are either in lower or upper case. This is also mentioned in Documentation/ABI/testing/sysfs-bus-event_source-devices-events "As performance monitoring event names are case insensitive in the perf tool, the perf tool only looks for lower or upper case event names in sysfs to avoid scanning the directory. It is therefore required the name of the event here is either lower or upper case." Change the Group #1 events names to lower case.
