Jin Yao c47a5599ed perf tools: Fix pattern matching for same substring in different PMU type ... Some different PMU types may have the same substring. For example, on Icelake server we have PMU types "uncore_imc" and "uncore_imc_free_running". Both PMU types have the substring "uncore_imc". But the parser wrongly thinks they are the same PMU type. We enable an imc event, perf stat -e uncore_imc/event=0xe3/ -a -- sleep 1 Perf actually expands the event to: uncore_imc_0/event=0xe3/ uncore_imc_1/event=0xe3/ uncore_imc_2/event=0xe3/ uncore_imc_3/event=0xe3/ uncore_imc_4/event=0xe3/ uncore_imc_5/event=0xe3/ uncore_imc_6/event=0xe3/ uncore_imc_7/event=0xe3/ uncore_imc_free_running_0/event=0xe3/ uncore_imc_free_running_1/event=0xe3/ uncore_imc_free_running_3/event=0xe3/ uncore_imc_free_running_4/event=0xe3/ That's because the "uncore_imc_free_running" matches the pattern "uncore_imc*". Now we check that the last characters of PMU name is '_<digit>'. For example, for pattern "uncore_imc*", "uncore_imc_0" is parsed ok, but "uncore_imc_free_running_0" fails.
