The event PERF_RECORD_TIME_CONV was extended for clock parameters, but the tool fails to be backwards-compatible for the old event format.
Based on checking the event size, this patch series can decide if the extended clock parameters are contained in the perf event or not. This allows the event PERF_RECORD_TIME_CONV to be backwards-compatible. The last patch also is introduced for dumping the event, for both the old and latest event formats. The patch set has been tested on Arm64 HiSilicon D06 platform.
