A perf uncore PMU may have two PMU names, a real name and an alias name. With this patch set, the perf tool can monitor the PMU with either the real name or the alias.
Use the real name, $ perf stat -e uncore_cha_2/event=1/ -x, 4044879584,,uncore_cha_2/event=1/,2528059205,100.00,,
Use the alias, $ perf stat -e uncore_type_0_2/event=1/ -x, 3659675336,,uncore_type_0_2/event=1/,2287306455,100.00,,
v3: --- 1. Use fgets() to replace fscanf(). 2. Resource cleanup.
v2: --- Add test case to verify the real name and alias name having same effect.
