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 callgraph 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. Changes since V4: - Fix issue of setting callgraph_set Changes since V5: - per-event settings over global settings in general - support for event post configuration structure Changes since V6: - Add error infor for per-event time - rename the option to call-graph and stacl-size - refine parse/config callchain functions, and reuse them for per-event callgraph setting - Modify perf test Changes since V7: - Rebase on 6ea3269c58 - Enclose callgraph reset codes.
