Subject: [PATCH 1/2] perf vendor events arm64: Fill up Desc field for Hisi hip08 hha pmu
In the same PMU, when some JSON events have the "BriefDescription" field
populated while others do not, the cmp_sevent() function will split these
two types of events into separate groups. As a result, when using perf
list to display events, the two types of events cannot be grouped together
in the output.
before patch:
$ perf list
...
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_sccl,hha]
after patch:
$ perf list
...
uncore hha:
edir-hit
[Count of The number of HHA E-Dir hit operations. Unit: hisi_sccl,hha]
sdir-hit
[Count of The number of HHA S-Dir hit operations. Unit: hisi_sccl,hha]
sdir-lookup
[Count of the number of HHA S-Dir lookup operations. Unit: hisi_sccl,hha]
