This patch allows setting config terms for legacy cache events. For example: # perf stat -e L1-icache-misses/name=valA/ -e branches/name=valB/ ls ... Performance counter stats for 'ls': 11299 valA 451605 valB 0.000779091 seconds time elapsed # perf record -e cache-misses/name=inh/ -e cache-misses/name=noinh,no-inherit/ bash # ls # exit [ perf record: Woken up 1 times to write data ] [ perf record: Captured and wrote 0.023 MB perf.data (131 samples) ] # perf report --stdio | grep -B 1 'Event count' # Samples: 105 of event 'inh' # Event count (approx.): 109118 -- # Samples: 26 of event 'noinh' # Event count (approx.): 48302 A test case is introduced to test this feature.
