Leo Yan aa616f5a8a perf jit: Let convert_timestamp() to be backwards-compatible ... Commit d110162caf ("perf tsc: Support cap_user_time_short for event TIME_CONV") supports the extended parameters for event TIME_CONV, but it broke the backwards compatibility, so any perf data file with old event format fails to convert timestamp. This patch introduces a helper event_contains() to check if an event contains a specific member or not. For the backwards-compatibility, if the event size confirms the extended parameters are supported in the event TIME_CONV, then copies these parameters. Committer notes: To make this compiler backwards compatible add this patch: - struct perf_tsc_conversion tc = { 0 }; + struct perf_tsc_conversion tc = { .time_shift = 0, }; Fixes: d110162caf ("perf tsc: Support cap_user_time_short for event TIME_CONV") Signed-off-by: Leo Yan <leo.yan@linaro.org> Acked-by: Adrian Hunter <adrian.hunter@intel.com> Cc: Alexander Shishkin <alexander.shishkin@linux.intel.com> Cc: Gustavo A.
