Adding a new hardcoded term 'name' allowing to specify a name for the pmu event. The term is defined along with standard pmu terms. If no 'name' term is given, the event name follows following template: "raw 0x<perf_event_attr::config>" running: perf stat -e cpu/config=1,name=krava1/u ls will produce following output: ... Performance counter stats for 'ls': 0 krava1 ... running: perf stat -e cpu/config=1/u ls will produce following output: ... Performance counter stats for 'ls': 0 raw 0x1 ...
