in the output.
before patch:
$ perf list pmu
...
uncore hha:
hisi_sccl1_hha2/sdir-hit/
hisi_sccl1_hha2/sdir-lookup/
...
uncore hha:
edir-hit
[Count of The number of HHA E-Dir hit operations. Unit: hisi_sccl1_hha2]
...
after patch:
$ perf list pmu
...
uncore hha:
edir-hit
[Count of The number of HHA E-Dir hit operations. Unit: hisi_sccl1_hha2]
sdir-hit
[Count of The number of HHA S-Dir hit operations. Unit: hisi_sccl1_hha2]
sdir-lookup
