This in term can reduce sampling overhead and the size of the perf.data. Changes since V1: - Break up V1 patches into three patches(parse option changes, partial time support and partial callgrap support). - Use strings 'fp,dwarf,lbr,no' to identify callchains - Add test case in parse-events.c Changes since V2: - Rebase on 60cd37eb10 Changes since V3: - Replace OPT_CALLBACK_SET by current existing callback mechanism. - Using perf_evsel__set_sample_bit if possible - Change the expression "partial" to "per event" - Using global variable to indicate if 'time' is set per event. If 'time' is not set, enable it by default for perf record.
