Subject: Re: [PATCH v3 0/4] Add support for ThunderX2 pmu events using json
 files

Hi Ganapat

This patchset has been tested on Hisilicon's hip08 board for implementation defined PMU events:
(1)perf list command is ok;
(2)perf stat command -e event_name:
When event number is less than 0x3ff, it is ok;
if event number is more than 0x3ff, it should be added this patch:

Thanks.
